As much as you hate FB, this might be the golden ticket to getting the site shut down. Just make sure you post a video of you running backwards through a cornfield too

Do any of you have dyno comparisons with a open cutout on a bolt on, H/C LS1? Gain wise. Tom didn't dyno mine with it open and after doing multiple freeway pulls with it opened and closed, there is a noticeable difference compared to when the car was cam only. If I had to guess, I'd say the car is putting down well over 450@ the rear with it open. Gotta get it back on the dyno!

mine was dyno'd with it opened

at english's dyno day and at PSI a while back i had them do a pull with it opened and one closed it only showed 2-3whp more with it opened. I might have the graphs somewhere, i'll check

A ls6 block makes no difference in power from a ls1 block they have the same pistons and rods year for year. My setup was 1 3/4 arh headers, fast 90 with a stock ls2 throttle body 2.5 ls6 heads and a tqv3 with a TOM WONG TUNE =)

That sounds about right with a stock cube motor and a good exhaust. Todd its probably just the extra noise that makes it feel like a Nascar car LOL

Haha. Well there is def some noise that's for sure. I'd say it's putting down more than 2-3. There's definitely a noticeable feeling power wise with it opened.

Unless you have some crazy bottlenecks somewhere my guess is 2-5 whp tops. My 402 in my z06 gained 6whp at the very tippy top peak with the exhaust disconnected.

Well *****. Either way it sounds like a NASCAR @ WOT

This just makes me want to cut the exhaust off of all my cars... I mean less weight and an extra 3-4hp is a win win in my book

The car really pops with it. Compliments my EPS cam nicely. If it adds more power then I'm good with that I mainly use it to substitute my horn. The factory horn in the Bird is rather embarrassing.

The first thing that had to go on my camaro was the polite horn.

on a dynojet, my LS2 GTO put down 17RWHP/20RWTQ (more) with the cutouts open

running shorties and catless mids with the cutouts before any bends

so yeah, i had good gains. i'd have to find the charts, but i did back to back runs with the cutouts open and closed. open was the way to go for sure.

That is a lot to pick up from a cutout I would think, unless your exhaust was pretty restrictive to begin with. ?

capped still had the exhaust going through the resonator and mufflers, so somewhat restrictive. open cutout was just shorties dumped to the ground

and the car was tuned with just a handheld diablo, so nothing really involved.

my placement.. as close to the engine as i could get (while still being able to reach and cap them)



here's a crap video with my longtube/cutout setup. the camera can't pick up the noise, but that's just at idle. car was ridiculously loud and painful to drive near redline. had the cutouts welded to the collector of the headers..actually cut a few inches off them..so that's about as loud as a stock LS2 can get

That is an insane pick on a relatively stock motor set-up.

I put down 27rwhp with just my slp sticker on my rear panel. this was using my hamster wheel dyno of course. I think you are getting robbed!

That sticker sure didn't help out when you ran Phil

Don't forget you also had a trunk full of dumbbells. Which would explain why your arms are so stacked.
