thank you myk. i knew there was a difference. and the Z28 i bought came wit the 2:73's and some of the others have 3:42 stock.

that was sarcasm

all ls1s are about the same as far as HP (around 345hp)

20camaro00

un actually no they're not thunderstruck507. i no for fact my car isnt pushing out 345 HP

Ya you have the car motor, not the corvette motor.

Mine has the truck motor, therefore it's not as fast as any others.

How do you know? Have you hooked up the motor to an engine dyno? T-struck is trying to say a stock LS1 motor, ANY stock LS1 motor, is the same as any other LS1motor and these things generally produce those kinds of numbers AT THE CRANK. Now at the rear wheels it's a different story but shucks, have you ever seen the 'mag article where a T/A out dyno'ed a 'Vette? Someone'll post that up shortly.

It doesn't matter if the LS1 is from/for a 'Vette, T/A, SS, WS6, Z28, Geo Metro COPO, whatever, and it certainly doesn't matter what kind of rear end gear ratio is there, an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1 is an LS1....

Irunelevens

It is. Or there's something wrong with it. All LS1s are basically the same.

20camaro00

yes i understand that an ls1 is a ls1. but then why did i lose to a bonestock TA wit a ls1.

Driver mod? Who knows, anything can happen on the streets...

we switched drivers after first race and then i won in his car

Very true. People are full of ****. All of the 12.8 timeslips that guys in the 5th gens are running obviously doesn't mean ****.

iTrader: (11)

how bad did you whoop him when driving his car? doesn't really matter though because if he was a bad enough driver...

any other details about your car? any mods at all, power windows, hard top, rear ratio still 2.73, weight reduction (or addition like a sound system)???

Not every LS1 is the same. It could be a factory freak. That is why we have some people dynoing 280rwhp out of the factory, and some well over 300. It all depends on the car, not to mention the gearing, he could have had an extra sport package w/o knowing it.

unit213

I don't buy the "factory freak" thing.

No, that's not why. Dyno variance is the main reason.

SStheBest

iTrader: (2)

i dont know unit...shortly after i bought my Z i was lookin at peoples numbers and mine did seem to dyno lower...320rwhp and 318 tq stock...after the mods it jumped nicley...362rwhp and 360tq. What im gettin at is the majority of 01's i came across was around 330-340whp+ with tq around the same numbers....lol i dunno apples to apples i guess...dont even get me started with the 02+ Z's

unit213

Forget about dyno numbers. They are irrelevant. When you talk ET and trap speed, they are all very close. The variables then become track prep, driver ability, and DA.

You'd really have to compare 98-00 and 01-02 though.

FlashLCD33

iTrader: (8)

Dyno numbers are pointless. For example, one of my friends car dynod 405rwhp at speed inc with a full boltons ls6 crate engine. We cammed it, took it to texas speed and it dynod 415rwhp. The difference between the car before and after, was HUGE. Definitely more than 10rwhp difference. Some dynos are optimistic, some are underrated.

Dynos are for TUNING ONLY. Not for measuring your (undersized) pecker.

Ouch!

the earlier engines had a larger cam and shittier intake, later cars had a better (ls6) intake and shittier cam

later cars also had newer head castings which might add a hair of rwhp...but as a general rule the ls1 is a ls1 as far as power output, which will be right around 345 flywheel HP

engines have tolerances so some run better and some run worse...but it's nothing to do with "corvette" this or "ss" that

as far as your race outcomes there a million variables...weight, gearing, options, level of maintanence, mileage/break in, ect

don't be suprised to get your *** pulled by a formula or a z28 just as easy as a ws6 or SS...they all got engines from the same assembly line

20camaro00

well some ppl dont consider fully synthetic oil stock so i guess my car cant be stock. its got power windows yes but hard top no. got t-tops. yes 2:73's and no it didnt have system at time. thats going to be installed friday

I don't either, however someone on a certain Third Gen site had a really good explanation of what a "Factory Freak" really is. It could really not apply to new engines due to new tolerance levels, but LS1's do still seem to vary by 5-10HP.

When every part is cast, its cast to a tolerance, this tolerance could range from 0.00%, -0.001% or +0.001%, whatever. We will use rockers for an example, as this is what was used as the example when I read it.

Machine casts 3 different sets of rockers for 3 stock LS1s on 3 different days. One is casted as a 1.695 rocker. One is casted at a 1.700 rocker, one is casted at a 1.705 rocker.

Car A makes less horsepower than Car B and C, however, if he were to upgrade to 1.8 rockers, he would gain more power than normal, as he would be making up for the original imperfection in the rocker.

Car B makes normal horsepower, makes normal gains when switching rockers.

Car C makes more horsepower, but makes less horsepower when upgrading rocker ratios.

This explains all the situations we get when different cars get different dyno gains but make near the same HP.

20camaro00: The car you raced was a TA and not a Formula correct? Formulas are apparently one of the lightest stock F-Bodys with the correct options.
