Run of the mill average H/C/I LS3 should be right at 500whp. That race is what I would expect out of a max effort 5.0 vs max effort LS1.

Nice runs.

V8EATR

He told me he ran it on two different dyno's. One was 420 with an unlocked converter and the other was 490 or 495 and I think that was locked. Don't remember what type of dyno's they were.

Car runs strong! You did well for being outgunned!

CamOnlyJabroni

Sounds about right then. Since most people don't go all out that want it to live and be reliable. I think the numbers I have seen were M6 5th gen cars. Which would be comparable to a locked converter.

Good runs Tye.

What "should" it run then? Especially without knowing the specific details of the car. Weird how you could know that. Or, are you assuming every single 4th gen should be setup exactly the same, every time, no exceptions, no matter what?

FYI, not every car is, or "should" be setup the exact same. Why can't you wrap your head around this?

R6cowboy

Yep, especially without knowing DA and track conditions. Apparently everything "should" be the same every time, everywhere.

Wait a minute. Are you saying different setup LS3's can vary in performance, power output, etc.? No way....

R6cowboy

Every chassis dyno "should" read the same too right?

Lol @ comparing dyno numbers.

The car ran 11.20 with a tight nitrous spec'd converter and geared for nitrous...That's slow... Again lol

CamOnlyJabroni

Close enough that the dyno where the converter was locked on was 5-10 hp off from what I said a average one should be. Thanks for playing!

Well....his rw and mine are similar. So it's good to know I'm not holesawed to death. Ported stock ls3 heads are pretty damn good. I would use gmpp heads as they are proven to make well over 600 crank hp.
I arleady said what it should run.

I wrap my head around what it should run. Realistically a bolt on ls3 should run his numbers easily in that car .

I'm just getting a kick out of all the "should be" nonsense. Now, what you say here I agree with.

R6cowboy

Does DA, track prep and other details make a difference in e.t.? Realistically, without knowing details no one really knows what it should run. Of course, same goes for mods other than engine mods. Put your LS6 and exhaust in an otherwise stock 4th gen and call it a bolt-on LS6 car. Without all the fine details as, lets say your car, it'll be a ton slower.

CamOnlyJabroni

Well we both know who the king of that is.

Motor swapped race Catfish barely wins and the forum loses it. Just another day on the tech.

5.br0 needs a boss manifold to compete with GMs finest. Boss manifold gains 100whp.

V8EATR

I heard 150whp and 15mph in the quarter.

Exactly my point......i know what my bolt on ls6 ran in many different configurations. Which is why i can say with confidence that car should be way faster. I ran clean to 11.5 with out even a dr on 18s. It woulda maybe ran a 11.4 that day but it was hitting the rev limiter at the 1000' mark. Still was on a ls6 intake, no rockers and heavier.

Sure da and track prep make some difference. The funny part about great da is that the track is usually cold and shitty. So alot of times it's just a trade off.

Damn good runs V8EATR! your car runs damn good and that was an honorable death. Imho all the cars in this vid ran damn well and sounded badass too. For a reliable dd ls3 hci 4th gen I think those numbers are impressive and on point. I was going to do a very similar build back in 09 when my 01 ss coupe blew it's motor. I bought a complete l92 engine, and spec'd out a cam and dod (vvt delete kit),All said and done I ws hoping for 430-460 rwhp (t56 car). I ended up selling the car and everything and went overseas for a year and a half. **** I would have been happy if my car ran like this 4th gen.

So you got yanked by a 420rwhp catfish. Sounds about right. Glad that's settled.
