Hey Give Me Your Ets And Mph And Weight Of Car , If You Have Dyno'd Your Car. I Want To Test A Formula To See How Accurate It Is. Let Me Try The Formula Then Let Me Know How Far Off It Is!
Thanks

ET 11.946
MPH 118.08
3440 lbs w/ me in it
yes i dynoed..... 343 rwhp 349 rwtq
ive done the formulas for my car, and none of them add up :dunno:

I Came Up With 401.5 . But I Do Believe This Is For Flywheel Horsepower ?
What Is The Approximate Driveline Loss On Camaros W/6 Speed 17% ? If So I Come Up With 333.5 . Interesting Gets You A Ball Park Without Allthe Same Variables And Drivetrain Loss .
Very Interesting
Thanks
Et 9.96
MPH 134.96
WEIGHT 3100 LBS
470 RWHP
I dont think the formula works:dunno:

i think ive heard w/ a m6 in our cars its only about 12% drivetrain loss

MPH is a better indicator of HP than ET. If you make a change to you
car, the best way to guage your improvement is with MPH. The ET will
come later on.

Hey Rpm Try This Formula Out With 17% Drivetrain Loss 470.9 Rwhp
Check It Out Again Just Ball Park
(vehicle Weight X ( Mph)2) Divide By (10,000 X Et) = Flywheel Horsepower
Then Multiply 17% For Drivetrain Loss Subtract From Flywheel Horsepower And 470.9 ! Interesting Gets You Pretty Close Uh, Ballpark Of Course.
Things That Make You Go Uuummm!

theres really no good formula
im trapping 118 w/ stock internals and no spray. im trapping the same if not a lil higher then ppl that have cammed cars and even H/C cars.

Your numbers don't add up at all. I've yet to see a car, without weight reduction, trapping as high as you do, with as little of power as you have. Chris81 on LS1tech.com cut a better 60' then you, and only trapped 113 mph as I recall, and he has 370whp. Either your numbers are off at the strip, your dyno is ultra conservative, or you aren't telling us your entire list of mods.

i have weight reduction, i never said i didnt.
its all about putting it all to the ground. and your location.
dyno was exact. everyone else dynoed what they shouldve also. remember that the 12 bolt will rob close to 20rwhp.
Atco and Cecil both have correct numbers.
i have no need to lie over the internet for that matter about my car. i have bolt ons w/ Stock Internals.
ive said it b4 and ill say it again. Who ever thinks im lying about not being SI, they can fork out the money to have my engine torn down. not one person has stepped up.
i now have a clutch and aluminum fywheel, i didnt make it to the last day at atco, but i also removed the rear wing and taped the front(tape is off now) Im shooting for 11.6/7 at hopefully 119. then ill put a cam in and go for low 11s.

OK, I missed the part about weight reduction. My bad. I read your website's list of mods, and didn't see anything about weight reduction.

my original post was based off my buddys camaro...
414 rwhp, no weight reduction, slicks, stock fronts,stock sus,bolt ons, stage 1 heads and cam.
hmmm... i thought i had weight reduction down... oh wait i did, b4 i changed the front page, ill redo it now.

That is wild. Where did you get that formula from?

Interesting Uh! I Got The Formula From An Old Time Racer. But Didn't Give Much Info On It!
