Yeah 750 isn't difficult with a 2200 I agree.

Seems like the majority of ECS 1500's are in the 650 range. I saw a video on one GS that was at ECS's shop that had a small blower cam as well. It made somewhere in the 700's. Probably best case scenario though..

i put down a little over 850 through an unlocked auto on a stock bottom end Ls6 with a 2200.

DOUG @ ECS

Basic break down of the 1500 here is;

550-575 with the restrictor plate in otherwise stock, 700 rwhp with removing it all together and adding meth & headers, and anywhere in between by modifying it. Removing the plate on an auto generally yields a high 9 second car @ 140ish.

Near or over 700 we use our stg 1 fuel system.

Adding a cam we have seen as high as slightly over 800 rwhp, but in the C7's Vengeance has broke 900 RWHP with the 1500.

The 2200 fully spun will make over 800 rwhp, 2200R/X 1000 rwhp.

Obviously there are many variables to this, built engines/manual or auto cam etc, but these are just some base numbers for you.

Hard to imagine. I have a 4" pulley on the blower, and an overdriven crank pulley. If The power is nearing the 850 and up range, I can install a restrictor plate.

slow goat

Thanks for that breakdown Doug. This should be interesting.

DOUG @ ECS

At 6600 RPM that puts the blower at 46,200 rpm, so you have some room to grow if you want to step up power later.

Now if you could just post a few of your tunes for us Doug we can let you get back to work

DOUG @ ECS

I offer the tune files N/C with the purchase of a kit.

schpenxel

Only messing around. Matt sent me a starting point back when I bought the kit. Between injectors, alky, cam, etc. that one is long gone.

i ran an 8"/3" pulley combo and shifted at 6900.

slow goat

The IW is 7.25" for the LS motor and I have a 4.0" blower pulley. I don't think I will be anywhere near yours. But I bet it was a blast to drive!!

What kind of torque did you make?

newvetteguy9

i'm def an odd ball but i've made about 830whp on a 1500sl. stock LS2 minus valve springs and cam. Stock sealed motor (not even head studs) the car is on e85 and is a manual. this is on a stock dampner and the 3.5 upper. car made many roll races, many dig runs, and drove almost 8-10K miles.... **** i was expecting it to pop on the dyno. I decided this year to go with forged 408 in the car just so I can search for more power. This is on a Dyno jet and a very well known and respected shop not someones back yard dyno voodoo.

slow goat

That's amazing! Do you have and dyno sheets? I'm really interested to see how and when the torque is delivered? What cam do you have? How much lift are those springs rated to?

DOUG @ ECS

I thought you had the 8" IW balancer, your blower RPM will be even lower then I posted above. I would think about a smaller head unit pulley, are you sure it is 4"?

slow goat

Doug, you are right. My mistake. I do have the 8" IW balancer.
Can you PM me pricing on a couple of parts I am missing? I need the extended coolant hose, the blower remote drain tube- I also ordered the charge pipe from the IC to the TB. I thought I was going to get it with a built in LS3 MAF slot. Is it possible to trade, and I pay the difference?

schpenxel

I have an LS3 w/MAF slot in black that I'm going to be selling soon if you need it

slow goat

Sure- how much and how soon?

schpenxel

Half of whatever retail is on it is what I'd ask for it price wise

I need it to get through annual inspection here. I'm going to put it on this weekend then get the car through inspection early next week, so by Wed/Thur next week I should be able to get it out to you

Doug will probably work with you.. but if you do end up wanting the one from me just let me know and I'll get it boxed up next week.

slow goat

Awesome, I have a polished kit, but I will contact you if anything falls through.
