E-Force 1590 Kit
Anyone have the 1590 kit installed yet on a LS3 A6 kind of curious what the RWHP and Torque would be on a completely stock engine with there canned tune. I'm guessing 460ish RWHP not sure about the Torque.

Edelbrock's claim is 554 flywheel horsepower for the 1590 kit. That number wasn't pulled out of old Vick's butt! It comes from testing in a very controlled, repeatable environment on an engine dyno and should be honest numbers. So if you assume an 18% loss (could be more or less) from the A6, this turns your 355rwhp LS3 into a roughly 460-ish rwhp Vette with a very mild 5psi of boost...a 30% increase at the wheels. Search the FI forum for 1590 and you'll find several builds with numbers to compare.

I have a complete Z06 exhaust on my car and if I throw on some 1.85 rockers on it and have the e-force canned tune tweaked would 500RWHP be a possibility
What would the torque numbers be?

If you are shooting for 500rwhp I'd change to the $35.00 3.5" pulley (1591 kit size) and add a Boost-A-Pump followed by a re-tune. That should put you right at 500rwhp, probably a bit over over.
I can't help you with the 1.85 rocker question....dunno.

Every car on every dyno on every day of the week is going to come up with different numbers. As I mentioned, I used a conservative 18% as a starting point. If the dyno numbers are a big deal to you I'd tell you to first put your "no longer stock" car on the dyno and see what it delivers. You do know the Z06 exhaust is going to affect the tune right? You are going to want to get the car tuned after the supercharger install. The canned Edelbrock tune will get you up and running but your fuel trims will be off. It was set up for a 100% bone stock car. The free flowing Z06 manifolds/exhaust is comparable to adding headers.
If you are shooting for 500rwhp I'd change to the $35.00 3.5" pulley (1591 kit size) and add a Boost-A-Pump followed by a re-tune. That should put you right at 500rwhp, probably a bit over over.

Thanks for the BAP instructions that you PM'd me the other day that still is a possibility.

Dyno numbers are really not a big deal to me, but I was hoping to get 500RWHP with 1590 kit with out changing the pulley and adding a BAP or a cam. I already plan on putting it on the dyno before I install it and I planned on getting a re-tune after the install I hear there tune is real conservative and they left a lot on the table and that's what got me thinking that 500 is attainable.

My LS-2 6 speed got 501 RWHP last week with the smaller pully, no BAP, bone stock otherwise, using a custom tune instead of Edelbrock's canned tune. My baseline dyno was 362, or a 10% driveline loss.
Your LS-3 should have 25 more HP at the crank than my LS-2 in stock form, but you also have higher driveline loss with the A6. So starting with 25 crank HP more than me, using the lower HP kit than I did, and getting higher driveline losses, makes me think 500 RWHP is not realistic using the canned tune.

FYI the Edelbrock tune targets a wide open/Power Enrichment AFR of 11.0 to 1 which is a bit rich. 11.5-11.6 to 1 is generally considered the sweet spot. There is also a ton of work that can be done with the spark advance tables.

I don't know that you'll see 500 RWHP through the A6.

No BAP your not running out of fuel?

Nope. My tuner tested the car without the BAP and found that with the 501 RWHP we were seeing, the data logs showed the fuel system was keeping up fine with the fuel demands.
Had we seen closer to 550 rwhp we would have moved forward with our original plans for the BAP.

think twice on the 1.8 RR with the E-force.
I made a post wondering the benifit of adding 1.8 RR to an e-force

My mistake, I was focusing on the text in your first post. Oops!

So when I go for the re-tune we could do a pulley swap and see what happens or would this not work on the 1590 kit and be a bad idea?

If you get the 1590 kit, the 3.5" pulley, and a BAP, you have just created the 1591 kit but with an alternate fuel pump solution.

....and without all of the hastle or labor expense of the fuel pump swap.

Also 62Jeff stated (Post #7) he is running the 1591 kit with out a BAP or swapping out the fuel pump. He stated his tuner said he had no fuel issues so the question is do you really need it if you use his example you could say no.
I'm new the FI world so I'm learning by asking questions.

There are hundreds of Vettes running around with BAPs without issue. It's a good alternative to those that don't want to replace the pump.
There isn't much if any cost savings if you are doing the work yourself but if you are paying someone else to swap the pump the BAP value is clear. Query the two high volume centri installers out there and get their spin on this one. They've seen a ton of cars.

I only make this point because I am not running a 1591 on an LS-3, I'm running a simulated 1594, minus BAP, on an LS-2. So I only know that my fuel system was adequate for my LS-2, not sure what an LS-3 would do.

To be clear, I have an LS-2 so I'm running a 1593, with the 3.5" pulley thus simulating a 1594 (the part number for the LS-2 big HP kit).
