And so it begins, C8 twin turbo kit at ECS
 

https://cimg5.ibsrv.net/gimg/www.cor...c7589b5a69.jpg

Most of the kit has been CAD'd already and is going into production. I don't know exactly how long this will take to be able to sell, but our goal is a 50 state legal turbo kit that you can bolt-on, download a tune file and go.I'll update this thread as we progress.

You'll need to add one of these to the C8 kit! :D

Oh my, I am going to want one of these.

Any estimate on rwhp?

Any idea of potential tuning options, fueling? Thoughts on the strength of the internals vs the LT1 cars?

I’m curious too. How are you handling the tuning side of this?

Sent a PM guys

I would assume they are not tuning it at this point. Race gas and a stock tune on 4-5psi might work until tuning is available to turn it up.

All questions I will happily answer as we generate the answers, thanks for the interest!

Hi Doug and team,
Something of interest would be to understand how compatible the LT4 or aftermarket LT-style motors are with all the rest of the C8 bits. For those going FI, buying a complete swap-in setup like that might be preferable to upgrading the LT2's internals.

The tuning part is what really interests me I know it will make power and sound great

how about a halltech or other aftermarket computer to add another set of injectors like the lt5 did?

the factory computer likely will still complain but you could use another standalone with wide band to give more fuel for the turbos

unlocking the global b isn't in the cards yet

torque limitations in the factory computer will still be an issue.

let’s give Dave Steck a chance. :cheers:

even when it gets unlocked and it will you know how much they are going to charge for a tune?

I’d guess $3k. $2500-ish in hardware, then labor. Fair price for an “uncrackable” ECU. :thumbs:

:lurk: I’m looking forward to the results!

From what I have read, the DCT is the weak link, as it's not able to take a whole lot more torque than stock. Of course like with cracking the ecm, all it takes is time and money, probably LOTS of it.

We are already on that! We are working with some DCT pro's to beef it up.

Will you offer any warranty on engines with the kit installed? Do you plan testing to determine the effects on engine longevity?

why should they?

It has been in my experience that aftermarket warranties basically have you pay for a catastrophic problem upfront, those who never have one, which is most, simply threw their money away. Look at some of the companies that offer it, their install price is double of those who do not.

We will rely on our 27 years of experience with installing and manufacturing forced-induction kits as our guide while testing on our own vehicle.

12 years later and the only part in the kit to fail was a bearing in an idler. Engine and trans still unopened.

The C7 wasn't different enough to have alongside the C6 but the C8 has my attention. Especially if you guys can put something together.

My C8 is on order once the Plant re opens she will be built hopefully. Any coupons available? lol ;)

That's great to hear, even at your power level so many of these are still going strong.

You would fall under the friends/repeat customer category! I didn't know you had one on order, that's cool!!

Slap Chris around for withholding information

Any updates with pictures?

Left side header is completed, welding up the right side now. I'll post up more when I get a few minutes.

Looks beautiful guys!

get real.

Right side is complete

Any chance there will be room enough to do this setup in the convertible C8 ?

That looks awesome! The fact you will be able to see it thru the window is great.

I’d love to see how the final costs come in for the kit which we won’t know for a while. But if you guys can sell them like you did with the blower kits in the past (lot of performance for the $$$), I’ll be a very happy camper!

great work!

Your guess is as good as mine at the moment, but I can't see them using this area for a top, too hot already.

So do you plan on obtaining a HTC for possible TT development then? Not sure I understand your comment on the retractable top and engine bay heat.....apparently GM feels it’s safe to have the top stored there with the shielding they have over the engine. Are you saying that you thing adding a TT setup would add to much extra heat that top could not handle? Thanks !!

I'm saying I have never looked at a convertible C8 before, I have no idea where the top goes at all.

Got it....well hopefully you’ll be able to work your same magic on the HTC . You’ll have a customer here if you can!

nice job! gravity drain, nice manifolds, looks very sweet. keep crankin!!!

Pretty sweet, got a depot on the C8, just not sure how long I'll wait, this may change my mind...

I like that its up high instead of on the ground near the rear bumper. I have no experience or engineering reason to like it better.

I would think that with two turbos and all the header work and plumbing, this kit will exceed the cost of a SC kit by a decent amount.
I'm also very interested to see what kind of power it will make.
I'm sure ECS will knock it out of the park.

Doug watched your ECS Youtube vid last night and it was professional and informative! I also watched LMR's vid about their upcoming turbo kit and it was informative as a wet noodle and totally useless! Total waste of time.
I know that your system will rock the C8 FI arena!

Between the greater expense in materials and the tuning costs, it will definitely be more than say a C7 supercharger install. We are also working on a supercharger option though which we feel will be more reasonably priced. Tuning will still be what it is though.

Thanks Nick!! I have not seen their video, but they do make some fast cars, I'm sure they will do great.

Can you post links to the videos?

Turbos look great. Can't wait to see the results

Just search "East Coast Supercharging" on YouTube, or there is a link in my sig. Thanks for your interest!

Awesome work guys! If the Z06 is NA like some of the latest rumors are suggesting, you guys are going to make a killing. I know I'll be giving you a call if that's the case. Would love to be able to hear a little turbo whistle during normal cruise and be able to handle 20-30 min track sessions. You think we'll see either of those in the final product?

Yeah I totally agree with you!
C8 Z will go back to its roots and be a car designed for road course lap times.
I say this BUT McLaren and Ferrari are making turbos work on the road course BUT remember these magazines are doing one lap wonders. Nothing like a SCCA 25 minute race

Doug on another note, I wonder if the C8 has a sensor in the engine bay that will put the car in reduced engine power if the temp in that area get to high?
If this is the case I am sure it can be handled even without tuning.
I know the Lambo Huracan can monitor this area.

One more thing...
Doug let's make some "Mexico" vids. Turbo system should be in soon for my Huracan.
No hero kit, boost levels will be low as I am sure yours will be too at first:cool:.

Looking forward to some FI on my new C8, have to finish the 2650 install on my C7Z first though.

not sure which part of California you’re in but if you’re close to the Bay Area and want an extra hand when this is all over let me know

That would be cool. In today's traffic I'm only 2 hours east of SF. :-)

Just finished up tuning buddies C6 ZR1 with Kong 2650.
Heads cam 2" headers and E.
CAR RUNS ITS ASS OFF!
Kevin your goingto love it!

BTW
Twins on the way for my Huracan.

SORRY DOUG for hi jacking!
https://cimg1.ibsrv.net/gimg/www.cor...e15135541.jpeg

Motech for tuning Nick?

Since Doug is lazy..lol

Lets be honest you’re not sorry or you would not have posted.

Ah yes I got your attention. Was reading that you have been playing with Motec!
Will be in the market.
OH but wait, according to others I was being dishonest.

So Doug Motec will build a Standalone for the C8 as will Syvecs. ]
Both companies have new C8 in their possession or will soon. One is a container heading across the seas now!

Sexy!!!

C8 development continues... as you can imagine, we are having to design and make most of the components for the C8 ourselves. Here is a set of exhaust flanges we designed for the turbo downpipes, 3D printed in plastic so we can test fit in a matter of hours, then laser cut in metal in a matter of days, not weeks, thanks to using the latest in technology available from CAD design to rapid prototyping here in house. We are not just making a turbo system, we are bringing it fully into production at the same time.

Great work/innovation! I can remember back when they said CAD was just a FAD. :yesnod:

Thanks, thinking back how we used to design things 15-20 years ago, it was so primitive and time-consuming. Now we had the CAD files from GM and made most of the system before applying any of it to the vehicle yet. So much nicer, cleaner, and more efficient.

https://cimg1.ibsrv.net/gimg/www.cor...ef4b341008.jpg

I thought a polished PD on top of the motor under the glass would be choice, but damn, those twins are purdy. Nice work Doug & Crew.

Twins are the way to go....

weight savings
 

Wonder how much weight a c8 could save if an engineer went over final drawings and did smart little changes ?
ie. the flanges in picture.
You could use only 3 bolts holding adapter AND the pipe/bracket going out to the right in picture..dual function for two bolts ? Clamp and hold bracket...
Bolt length etc.

Doesn't seem much to shave of 15-20 gram of each bracket/bolt setup..... but material cost and weight savings of a few percentage could actually be measurable in final product.
I always looked at my previous C5, C6, C7s and wonder why a bolt has to be twice the length, or why door bracket had to be that solid , thick and material everywhere.... :-)
2% saved weight would mean 72 pounds and less material cost...
Oh well its nitpicking on a wonderful machine for a fraction of the cost vs others...

Just did an comparison.
GMs number show that they expected 3.3 billion USD sale 2020 Corvette with a 16.5% profit margin, lets say average sale price is 75k, then cost of every car is 63k, so base cars will net them absolute nothing or close to nothing.
Now take Porsche 911(992), they have 47% gross margin on sales of 8 billion USD (6.9 billion Euros), average selling price 140k and cost on car 74k USD......

Thank you GM for delivering a extremely good value performance car..... forgive me nitpicking, but you have more to extract of same investment :-)

Bracket design
 

you shorten the hanger and weld directly to the flange thereby eliminating both bolts, holes, flange etc. Then you slip the grommet onto the hanger and bolt to trans. Change the sequence and eliminate MORE mass!

Can we just get one on the car and make changes of that nature before final production runs are made? :rofl::rofl:

Same goes with our supercharger kits, we streamlined things over the years, but we have to start somewhere and changing the 160 lbs (or close to it) exhaust out to something a 1/4 of the weight will mitigate any extra bolt or extra flange anyway.

It was never against your build, it was a general note on GMs design. :-)

:lurk:

another week gone by, any more teasers for us :-)

Cant wait to see this running !

regards
Rune

Hey Doug! It's been so long. I hope all of you guys are doing well.

I imagine the supercharger isn't readily feasible due to the front of the engine being right up against the firewall?

Turbos look great there. Looking forward to the results.

I saw Nick Yoskin made a cameo so I thought I'd get in here too.

The shaft faces front but the TB mount faces rear. It's only a design constraint that the shaft faces opposite. Whipple will have a nice unit made for the application. LT 6.2 liter motors make 800-900rwhp using their 2.9 liter units so I imagine the C8 will be a 0-60 in 2.4 second monster. All you need then is a little ECS tuning magic with a meth kit.
https://www.speednik.com/files/2017/...49-640x427.jpg

Holy shit a SpinMonster siting. I haven't seen you on the forum in ages. I am kinda wishing for a feasible supercharger setup for the C8 as well. PD blower would be ideal.

Me too! We are working on the CARB certification now while we wait for the tuning. we really do not have much of a choice but to be patient, unfortunately.

Hey long time no see! We are doing great, I hope the same for you.

We are going to work on a centri kit for the C8 once this is finished utilizing a jackshaft and mounting the blower down under the exhaust, but the turbos were an easier fit so we started there. That said the turbo kit will be fair amount more money than a centri kit so we want to offer both.

That twin turbo kit of yours is going to be sweet!
Well worth the money, IMO, and I don't even know what it will be priced at!:thumbs:

A friend who builds turbo kits took me for a ride in his TT Gallardo. That is insane power delivery. I can live with either. Doug's location for the turbos is better than the Hennessey location so I am interested. Regardless of either power adder, I have seen behind the scenes at ECS and they are really good at the art. We are fortunate to have so many top shelf tuners around the country.

I'm fine. Staying out of trouble.

I get the cost thing. I think the turbo install this application is better for me though.
I'm hoping HP tuners gets through the tuning barriers soon so we can see some results.

What do you think the clutch will hold?

Hey, one more thing Doug, will this void the warranty?
https://beatingcowdens.files.wordpre...lol1.jpg?w=760

Doug, obviously your not ready to at the moment, but would you be looking to make cast (hopefully stainless or Inconnel) manifolds for the kit? Would offer much better strength and heat retention than fabricated headers.

The final revision will be Inconnel, it was the plan from the start. :thumbs:

So cast Inconel manifolds?
That would be sweet and, just a guess, fairly pricey.
Still think it will be worth the extra bucks.

:auto:


I pray for Dodson Sportsman not to be pricey like Huracan Sportsman 9!
Embarrassing to admit what I paid.

We wanted to make a top-shelf turbo kit, we are undecided as to whether or not we will offer different levels of it until we see what the market calls for.

Sub'd.

So you acquired the CAD from GM, or GM gave you the CAD?

If GM gave you the CAD drawings then I would guess you and others know a bit more about the tuning situation than you are allowed to say.

I would assume all we will hear is crickets from this post. Thanks, Jason

The CAD drawings actually come from SEMA, but you do have to explain why you want them. They won't just give you the drawings of the entire car unless you can give a good enough reason for needing them.

We do not have any super-secret sauce on the tuning, we are waiting like everyone else. You may have seen another C8 that finished the turbo kit and made pulls on the dyno, but you won't see any track times until the tuning is available because it won't shift. We are applying for CARB certification on our TT, we are hoping that gets us that much closer to getting the tuning, but we are not exactly sure. It will come, but I don't know exactly when but in the meantime we are going to have the turbo kit ready for production so we can hit the ground running the day that it is.

Thanks for the explanation, Doug. Much respect! Jason

Everything is coming together, currently, we have the air filters on the turbos themselves but we plan to make the next set of manifolds pulling the turbo's back just a touch so we can get a duct on there and place the air filters in the cold air inlet area on the side of the car.

Count me in.

I like the way that's all tucked in there.
Very well done.

Nice. Looks like it might also fit the HTC.

Looks great. How long until the weak tranny gets solved

We are already on that, of course, everything still goes back to tuning, but we are working on the mechanical portion of the trans with the help of some DCT pro's.

need a beefier clutch solution (on the way), and ability to tune both the engine and the torq management for the tranny and shift calibration. Some "posers" slap turbos on and call it a day which right now is a waste IMHO.

This is a very well thought out setup with the turbos up tight to the exh port. Be nice to do a cold air solution for the inlets. Good work guys, keep up the solid engineering, the tune will come some day!!!

My thoughts exactly.
This thing is going to be responsive.

very interested ! watching all the C8s with add ons, N20 or turbos videos.. while they make 300whp more over stock, they are pulling horrible 60-130 times and 1/4 mile times. You take a GTR from 470whp ( 122 1/4 ) to 700whp and its a 10.1 @137-140 in 1/4 .

the Vette being lighter it should run easily 9s at 140 on pump. I am sure that all the tuning .. for right now not impressed with the MPH gained.

my GTR weight 3770 making 820whp( mustang Dyno) ran 9.5s @ 151 at 6000DA ( I was on E85 which is huge advantage )

will be looking for a slightly used Z51 😁

I agree with you. Late model racecraft in Houston built a bad ass TwinTurbo set up, but it’s slower than stock. Show me some dragy times. Their transmission is slipping like crazy.

Steven will say it makes 670 hp on the dyno… OK, it doesn’t make it on the street. All it takes is watching his video. He claims it is wheel spin… No, transmission slippage.

Steven, do you disagree?

Respectfully, no need to clutter up Doug's thread.

Steven has been 100% up front that the blue car and the red car have tranny slipping issues. He said they had to turn the boost down to get the tranny to cooperate. No car is going to perform without tuning, regardless what any shop says.

They have the engine and tranny out of the red car to strengthen the tranny. Without tuning right now these builds are just marketing and preparation for when there is tuning.

You are correct. I will back off.

what's up bro!! ?? where is Nick Y ?
