Steve from SNL/Monster Clutches emailed me about a post I made on ls1tech and we got to talking. One thing lead to another and I was given an offer that was ridiculous to pass up, so I took it. Steve sent me a level 2 twin with 28lb flywheel, and the made me some disks that would be better suited for my current builds end output.



This is some's standard level 2 twin I pulled from Google


This is mine



It's a sintered something metal lol. It looks like my buddy's level 5 disk from his VR4, but his was a copper/bronze color.

I'd say this is better suited than the RXT hahahaha. Steve told me that this setup even with the 28lb flywheel is still "considerably lighter" than my monster level 3 with their old chromoly 15lb flywheel setup.

Hurry up and get to the turbo work

Nice work man. It will all be worth it once you hit the boost pedal

sabastian458

I'm delaying the turbo work for a bit, need to get another DD on the road within 6 months. I know if I put the Vette back on the road I will never finish it, so I am going to get the cummins up and going. Nothing like 20-22mpg out of a 7-8000 lb tank hahaha


I need to keep an eye out for some C6Z06 or such cat pipes for the flanges. Or I may cut the flange off the manifolds and run some pipe into a v-band connection. Everything hinges on me getting the block to the machine shop and back.

Finished the DoD tower tapping, made sure each NPT plug screwed down below the top by 1 thread (to give room for sealant) and then used a fine triangle file and knocked the top of each tower down slightly, had a bit of a bur from the tap. Now I'm going to get it to the machine shop to hone/bore the block. I want to take my own readings for each bore for my records and to make sure the machinist doesn't screw me.

Anyone have experience with an Eastwood 200 TIG welder? I want to pick one up and it's in my price range I can spend. This will be used to do at home things, and finishing my build. I know after I get better at TIG. I have a Harbor Freight special TIG that I haven't hooked up yet, don't think I will either. I know I don't have the funds for a Miller or Lincoln, new or used.

I have one of their Tig 200 ac/dc units. No complaints here at all. Easily have over 15 125cf tanks, and 6 250cf tanks though it wihout issues. Pedal pivot is backwards compared to lincoln/miller/etc. but have found it to my liking since it's like the gas pedal in your car

Only 2 additions I would recommend. Get a quality gas lense setup for the torch (WP-17 style comes with it), and replace the ground clamp with a tweeco or equivalent.

One of these days when I feel the welder is actually holding me back, i'll upgrade. Until then I regard the only set-back being between pedal and torch

I was looking at a water cooled torch but couldn't find someone who listed what they used to make the switch.

Great looking welds by the way.

JDS99

Honestly I don't see the need for watercooled, unless you plan on loooong runs or almost no break between runs. Which you can't do with stainless anyway or it will overheat and warp to ****. The only time the torch has become a bit too hot to hold was when I was trying to weld up my welding table. Giant sheet of .25" 6061 with a 200amp tig.. I was running flat out on max for minutes at a time to get it hot enough to wet, and after several minutes it finally got too hot to hold. Was wayy too much job for the 200amp welder. Even during that, the machine never missed a beat. The big cooling fans on the back do their job well.

Awesome to hear, I'm going to place mine on order

andyyi

your build looks awesome. when you get your turbos on...oh man it makes the driving experience all that much more sweeter.

sabastian458

I have been day dreaming almost every time I'm in a car about driving my car. I am axious to get it back going. Waiting for some rewards card money to come through and then I will be buying my welder (need that to do some modifying to the radiator cradle and build the turbo system)

Just hard to do 2 builds at the same time and now I have to pull the head on my use to be rock solid truck. Thankfully I have an electric car to drive as a DD for now. I leased an imev from Mitsubishi.

I picked up an ECS Torque Tamer as an added safety margin. Came without installation instructions, even though it looks pretty straight forward it cam with 2 self making nuts for blind holes and an extra strip of metal. I sent an email via their sight the other day but no word back yet.

I found a machine shop I'm comfortable taking my block to finally, but I'm going to have to wait a bit longer due to my Yellow Truck. I'm buying a reman long block for it for $3200 with warranty, which is just a tad over what it would cost me to patch the truck up. First financially intelligent decision made lol

C5R UZR

Subscribed! Enjoyed reading through your build. I was gonna comment that yes you can tap and plug the oil towers (I did mine last Spring), but I got further in and realized you'd already figured that out. What did you learn from DTE on the upgraded washers? I'm looking at their price list and it looks like they've dropped from the 2004 intro price of $50/PR to $11 each, which after shipping makes them about $30, compared to the C6Z (19132817) at $14/pair... not sure how much better the DTE's are though. I've heard some say significantly, others say they look almost the same.

sabastian458

If memory serves me correctly they said if you werent running their clutches they didn't advise their springs. I went with the C6Z06 clutches and springs due to price and I got them quickly.

So it's settled, S366's are for me. The S256 wouldn't flow enough lb/min based on my calculations and the S366 should handle it.

Calculations are; estimated hp 1300 x 15% estimated drivetrain loss = 1,495 flywheel hp.
1,495 / 10 = 149.5 (fly hp / 10 hp, 1 lb/min = aprox 10hp)
149.5 est lb/min / 2 (twin turbo) = 74.75 lb/min needed.

Desired psi 25 (max effort) + 14.7 = 39.7 / 14.7 = 2.7 pressure ratio

This puts me at aprox .62 efficiency and on the threshold of the choke point. I can life with that for the max effort level hp of near 1300 wheel hp.

Same formulas for my DD level of aprox 850 whp.
850 x 1.15 = 977.5 / 10 = 97.75 / 2 = 48.875 lb/min needed
(15 psi + 14.7) / 14.7 = 2.02 pressure ratio
This puts me in the .74 efficiency in the turbo, just below the island of .76 which is much better. I think I can live with this more than the S256.

Granted I know there are a lot of other variables that will contribute or remove potential power/torque, this is just to help me estimate what will most likely work better.

I will try to order turbos soon, have heard Borg Warner will be increasing the price of the AirWerks turbos soon. $635 shipped for 1 turbo is a terrific price.

sabastian458

Ordered 1 S366 to see if it will fit. Should be here in about a week or so.

I sold my LS9 cam and my unused Hinson transmission mount and an old engagement ring so now I have some RACECAR money lol!

Looking for opinions on the Johnson Lifters. I read about them having a lifter that was using a bushing instead of needle bearings and that's what I want, but the ones in the link are the only ones I can find for sale. If anyone knows what I'm talking about please chime in!

Also looking at going with a bigger cam. More I think about it, the more I want a noticeable idle. Now that the Ls9 cam sold, I have a reason to get another cam lol. I'm looking at the England Green Typhon (25x duration, .630 lift, unknown LSA) or maybe a custom specked cam. Any thoughts on what works for a low compression 403?

Rkreigh

nice build, time to plan out how to hook 1300

I'm going with boost by speed to ramp up the power and hopefully keep the build 4l65E RPM tranny alive

I think comp make a nice solid bushing lifter but not sure they have it yet for the ls motors

good luck and thanks for posting the pics!

So zombie thread revival.

So some updates, been forever since the last.

I have the block back from the machinist, began file fitting the rings and test fitting the rotating assemy then back to the machinist for balancing.

Top end work began earlier this month. Sent my heads, I take, and throttle body to Tony Mamo for some of his work. He is also going to supply me a set of his short travel lifters and will spec a cam for the heads and my goals. Shooting for as close to 500 wheel NA as possible. Those should be back to me by end of July mid August.

sabastian458

Bore all cleaned up


Deburing




Oil crossover


Rod bolt clearance


Cam bearings installed


Last set of rings to be file fitted- Top= .020 2nd= .022
