Bullshit. Bad dyno operator.

That is a pretty healthy setup. The Kooks are just about the best for power, & the water pump & LSX are both good for up to 10hp, and the flywheel might trick a few more out of it by rpm-ing faster. But 400rwhp is a LOT from a stock motor. Maybe if this were true also:

LS6 block (25% OF 02's got them), 1.8 rocker arms (according to "the rules" this still qualifies as stock internals), MAF ends & ported TB....no cats, a cutout, etc. Oh Hell, just say bolt everything you can think of on it, and then MAYBE! But it would have to be a perfect match of parts. And it would have to happen in Texas.

Sorry, an HONEST 400 ft/lbs of TQ internally stock on a dynojet ain't happening.

from what i seen on the car the mods looked to be kooks 1 7/8 long tubes with a true custom mandrel bent 4 inch exhaust with a single 4 inch borla muffler and turn down, it has a big mass air and lid with no filter and a lsx intake with a electric w.p and no a/c belt and an edit tune and the car was low on gas if that matters those car usally make around 320 stock and add a set of kooks long tubes 1 7/8 with a custom cat back 4 inch id say you would get around 350 to 360 hp and the lid and maf combo im sure is good for 10 right so theres 370 or so and then the elect w.p gained i think 5 to 10 so theres 375 to 380 then you add the lsx intake there another 10 to 20 from what i have seen on here plus a good tune for all these mods that seems like it would make close to 400 to me i could be wrong i am not a ls1 master but?
sounds to me like he knows edit pretty good too. i know on a certin vette that did like 300 to the wheels then got a 1 7/8 headers and exhaust and a tune for the combo and pulled out 350 or so hp, and have seen it do it on only those mods but like i said who knows?
and yes i might get flammed for this reply but what do i care.

i hit the wrong reply, pardon me

DenzSS

You just can't add up the gains like that. If you hit 350rwhp internally stock you have done a good job. Anything else is BS or a bad/deceptive dyno operator.

HP gains are not linear. You can only go so far before you have eliminated all significant external bottlenecks.

and thats a reasonable reply in some terms sounds to be correct, but how with the car on the dyno and being used all day can he get the numbers to change in his favor im curious? i mean cause most cars there did alil lower than there dynos not to long ago? and also i thought dynojet is the standard for most hp number because you cant munipulate the numbers? right or wrong? and if the car went to a diffrent dyno place with a diffrent operator and still on a dynojet would that make a diff. if it did the same numbers?

H82BBad

people are not saying he got the numbers to change. They are saying that the car is not stock on the internals!

DenzSS

People lie all the time. What I, and others, have said is correct.

Keeping it conservative and giving a M6/10-bolt combination a 10% drivetrain loss equates a 440fwhp internally stock motor. That gives us a 1.27hp/ci efficiency. Considering many head/cam cars do not reach that level, a stock internal motor in no way may accomplish that feat.

1.25hp/ci is considered to be a good, well built motor. Internal work has been done. The stock compression ratio, cylinder head charactics, and cam profile dictate that 400rwhp from an internally stock motor is IMPOSSIBLE. I've seen and/or dyno'd around 100 LS1s and LS6s. 350rwhp is a very high mark that only a handful will meet. I've seen it, but it is incredibly rare.

I have 750-800 Ls1edit files in my computer, so I have done my fair share of dynoing I have NEVER seen a stock F-body dyno ANYWHERE near 400rwhp. I have had 2 cars, both 02's...that have full boltson, duals, ect....tuned to perfection, make 366-370rwhp. I can't see another 30 rwhp in there, anywhere!

I think Silver Slayer was looking for fact, not opinion.

I am the tuner and the dyno operator. I can assure you there was no funny business. Anyone who doesn't believe it can put your money where your mouth is.

There are a lot replies to his post from reputable tunners that state what they know from their experience in their day to day workings with the LS1. I'm sure that you have your own experiences working in your shop. So from what they've delt with it fact. I personally don't see how it could be 401/400 through a stock enternals motor with bolt-ons considering some h/c cars don't reach those numbers. Maybe the car mentioned was a freak to start with, and with your "X" package it made 401/400 some of them just said it was rare. If the "X" package is as good as you say it is and its on the cutting edge your going to have to endure a little :BS before you get the praise. If its that good you will have lots of business in the future. I think the thing here is repeatability. I know no two car are alike but if you can duplicate the numbers with your package on other cars it might be more believable. Maybe you should put your money where your mouth is!

H82BBad

how about that xxx package? Have you ever done one yet? 560 rwhp in a hyd cam 427 stroker?

1ORANGEWS6

Hmmm... from reading your sig I would think that you would be Brent. Who are you asking those questions to?

Unusual T/A

Total bs and nothing more. Someone can't operate a dyno correctly. I did 368/378 stock internal. 400rwhp is not possible with stock internals ROFL!

H82BBad

You're not fooling anyone who's been around the block a time or two. You can't get that kind of TQ internally stock. It just won't flow that kind of air even with ALL external restrictions removed.

Money where my mouth is? Sure..but how? Do I doubt that the car can come to ANOTHER unbiased dynojet and lay down over 400/400? No. Do I believe it internally stock (in my book that means LS1 cam, untouched LS1 heads, and never having had the valve covers off) and NA? Not on your life. I was pulling 11.5s internally stock 4 years ago when most of the rest of the best were still in the 12s. And I've put down 359 RWHP with an internally stock '02 A4 LS1. I KNOW all the tricks and I know what these engines are capable and 400/400 ain't it.

Electric water pumps and LSx intakes don't add that much to a bolt-on car for those of you who are buying this. All the rest of the mods are pretty standard, IMO.

The whole thing about factory "freaks" being factored into this equation, I still dont really see a way to get those numbers. Your car has something, whether you admit it/know it that is getting you those numbers, whether it be the actual Dyno or a mod. I say you take it to a reputable dyno and have some witnesses from this board go along if you are as confident as you seem.
