Can you add a cam to the kit and some meth and get more power? With the Edelbrock. They claim 599 FWHP what is that to the whells? What kind of power are you getting? Does it create alot of extra heat in the cabin?

 

You can get more power by just tunring up the boost a bit. You can also add Meth injection too. You can add a blower cam but it depends on how much power you are looking at. The base kit will produce 525-535 on an Ls2 and 550-565 on a stock LS3... Hope this helps.

 

I would like to get around 600 rwhp. Is that doable on a dailey driver?

 

Edelbrock's numbers are flywheel HP not wheel. PM member Motorhead-47. He has this SC with cam and headers. He'll be able to tell you quite a bit.

 

PLEASE don't give fairy tale HP! If the number does NOT mean RWHP, then don't try and fluff it up with the GM method of horse power rating. I want 500+ RWHP with the Edelbrock kit. Short of that, I won't buy it. Simple as that.

Thanks,

If all you want is just 500WHP you could save your $6500 and just do a cam and some mild head porting on your LS3 (I am assuming you have an LS3 since that is all the E-Force is made for right now).

BTW the E-Force was most likely developed in an engine dyno so there is no "fairy tale" about those power numbers. Yes they are crank but that IS the industry standard (which has nothing to do with GM; the SAE (Society of Automotive Engineers) comes up with the guidelines for the test). It still translates into low to mid 500WHP on a chassis dyno too.

 

RWHP or don't talk numbers. People don't want to ask what the numbers are calculated to represent. I refuse to say my car has 400 HP because it doesn't. I will toss it on a dyno someday and get a RWHP number and use that when people ask. My old 98 Camaro is running 635 HP, want to guess if that is crank or RWHP? I'm not trying to start a fuss but I've used RWHP for far too many years to get sucked in to the SAE guidelines for horsepower computation. SAE isn't doing squat for me for a cam, heads, or forced induction horse power calculations.

I don't want a lumpy cam or head porting and my 2007 has the LS2 AND the Edelbrock is being ordered now for release on the LS2 this month.

Owning a Corvette does not require me to speak SAE for HP numbers. When I talk to fellow enthusiasts about horse power, it's always RWHP.

I just finished up my install of the e-force 1591 kit on a 2008 LS3 Corvette. I added ARH 1 7/8 headers, blower cam (226/246, ~.600 lift, 118+4), and the included Z06 fuel pump. I haven't driven it yet as I need the tune and right now I'm scheduled for Tom Wong to do the tune on Aug 2. I'll provide dyno numbers once it is complete. I have the baseline on Tom's dyno so I should be able to show the power difference.

From what I've read the 1591 kit will get about 520 to 525 rwhp once the tune is tweaked. With headers and a tune I've seen some posts with around 575 rwhp. Redline Motorsports had around 630 rwhp with the 1591 kit, headers, and cam, at 7.5 psi.

My goal is 600 rwhp with the stock pulley. I wouldn't mind adding meth for the insurance. But, I'm not sure if anyone has done that on the TVS rotors. I don't know if it would damage the rotors.

Motorhead-47 installed his a few months ago and does his own tuning. He is a good resource on these kits.

 

How much did that cost you?

 

 

I'd guess a little over 10K for the 1591 kit, headers, cam, 921 spring kit, katech chain, pushrods, and tune. I did the install myself (with many phone calls to Motorhead-47).

You could save a little $$$ if you go with the ZR1 cam. LPE sells it for under $200 and you may be able to use your stock springs. It would probably get you to 600 rwhp (or close anyway).

 

Thank you

 

We just installed the 599 LS3 kit and made 513 wheel with stock blower pulley and stock exhaust on a seriously HOT day.

On the same LS3 in a Camaro with LT's and a cold air kit and smaller pulley we made 595rwhp and 605rwtq. STOCK CAM so great drivability.

PM me for details or any tech questions you may have. We have sold dozens of these systems and even have a few more stock orders coming in soon for the 1591's!

 

I am thinking of going with the STS turbo. I am torn on what way to go.

 

$6.5k for the 1591 kit shipped to my door
$1.7k for the complete LG Motorsports G6XE cam kit
$1.6k for the Kooks 1 7/8" Coated headers with cats

...plus a few bloody knuckles and a lot of brain cells expended...I do my own wrenching and tune my own car

 

Thank you so much. Are you happy with it? What is your rwhp?

 

Wow dude, you need to slow down there with your coffee cup. Take a deep breath, calm down... The E-Force was developed on an engine dyno, so they quote the engine horsepower it produces. If they gave you a RWHP number, for, say, a manual C6 Corvette, the guys with automatic cars would be crying about not getting those numbers for example. Quoting crank power makes sense in that situation.
No one is talking about taking a chassis dyno result and multiplying it by a fudge factor to come up with an imaginary CHP number; the numbers quoted are measured and they are a hell of a lot more accurate than any chassis dyno you've ever been in.

Factory engines are developed and tested on an engine dyno, so the power number manufacturers quote comes from that. The ridiculousness of using RWHP numbers for everything becomes glaringly obvious once you realize even something as simple as tire selection or the inflation pressure on your tires can show a gain or a loss of 50 or more horsepower on the dyno. Quoting RWHP for everything is also pointless because you'd have the exact same engine showing wildly different power numbers for different cars with different powertrain configurations such as auto vs manual, AWD vs RWD vs FWD, different final gear ratios, different stall speeds, etc. Its funny because fast drag cars always show much lower RWHP numbers than a car with a stock drivetrain since the high stall converter and higher final drive soaks up a lot of power, as do tires with soft sidewalls. So what does that RWHP number really tell you when making modifications that reduce it actually makes a car go faster?
And that's without mentioning the fact that the each different dyno brand reads differently, and even the same dyno can read differently in different shops. You are glorifying wheel power numbers without realizing that they are much, much, MUCH less accurate than an engine dyno...

 

I'm too old too slow down. If I slowed down any more I'd be taking a dirt nap! I still will use rwhp. I can relate to it and it is a hotrod standard, even as terrible and inaccurate as it is.

This is my car that A&A did in the attached links. It's a 1590 kit with a 3.5 inch pulley and Boost-A-Pump. The car is / was stock except for the B&B Fusion Exhaust. Otis Edelbrock Jr. lies about his tunes producing said power/torque. After Andy straighten out the tune the car made 513 WHP / 506 WTQ with his conservative tune on 91 octane.
I ‘ve read another post on the forum where England/Green did a similar install with headers with I believe 506 WHP / 520 WTQ. I hope this information helps.
The torque is a killer from 1600 RPM up.

If I interpret the original thread correctly, they got 482 at the wheels, and working backwards predicted 567 at the crank. Sounds like if anything Edelbrock underestimated the output?

Or is that a tongue-in-cheek comment? I ask, because I've got money down waiting on the LS2 kit to arrive at EnglandGreen and am curious if you feel the kit is underperforming.
