because thats ford's job

EDIT: On the other hand, an auto trans DOES have higher losses than a manual, so in hypothetical identical cars with an a4 and an m6, the m6 will have more whp right? Well I guess you were talking about CHP though...

oh God. please stop. i can't take it anymore.
LS1 f-bodys and LS1 corvettes have the same horsepower at the crank. f-bodys dyno a tad HIGHER because of their solid rear vs. the corvette's IRS, assuming they both have the same transmission. a magazine did a direct comparison. the f-body dynoed higher. the corvette will beat the f-body in a race because they are a few hundred pounds lighter and more aerodynamic.

anyone that tries to disagree with me is wrong. this has been PROVEN.

I was just about to ask this same question. So my 02 Z28 must have around 350 horses or so. I knew they advertised them as having 325 on the net.
How easy is it for the LS1 to beat a Hemi? I let my cousin use my car the other night for work, since he had no gas and he said a friend of his from work has a Hemi. Didnt say what kind of car, just the engine size. They did 3 honks on a rolling start. He did say, he let him get ahead some before he punched it and quickly caught him and beat him.

it's pretty simple for a stock f-body to walk an SRT8 charger if you don't horribly screw up the driving

Not to mention that SRT-8 chargers/magnums come with 440hp. Thats quite a bit more then the 385hp the Hemi comes with.
They are faster then 14.0 cars. Just because your barely in the 13s and beat one doesn't mean you'd beat one in the 1/4.

Another question, if i just decide keep the exhaust i have, am i able to put bigger tips on it?
When i get a chance, ill take some pics of the exhaust system. Looking at the Ls1sounds.com website, the only one's i can really compare em to by look are the Bassani Aft Cat or even the Magnaflow exhaust and the Borlamouth tip's look.

Also the LS6 intake difference so 01/02 cars came with more power..
Different heads on some year models, also the cam size differences..
Not for sure about this but i think that some years had bigger injectors also.

barely in the 13's? 13.6 isn't barely in the 13's, especially for a catback only car in the middle of the summer on a 70+ degree night. give me a cold day and with my mods know, i can likely turn a low 13 or better. i think that's pretty good for putting $400 i mods on my car, and i don't plan on much more anytime soon. you can have fun breaking your ****. i like my daily driver how it is.

I agree with you though that LS1s are LS1s and all kick a ton of *** give or take tenish hp.
EDIT: On the other hand, an auto trans DOES have higher losses than a manual, so in hypothetical identical cars with an a4 and an m6, the m6 will have more whp right? Well I guess you were talking about CHP though...

Ahhhhh now come on damnit! Don't try to hang me on a minute technicality. Before the ******' cars were sent to SLP thet damn things had the same horsepower. Of course when you send 1 out of every 100 made, to a performance upfitter....then they'll have more horsepower! What I have PROOF of and what is the standard practice with all GM employees and everyone that knows anything is.....before SLP or Anyother shop gets a hold of an LS1 powerd car....all LS1's were built with 350HP at the crank.
That's the last time I'll chime that one in.....if you have a problem believing that....then it's a personal problem within yourself. Good day sir.
