check out free drag simulator. it's based on manual, but you can add about .3 sec to the 1/4 to get the automatic. just because there is a little more power loss in the drive train for an auto. www.speedshoppro.com

yer probably dropping the clutch. you need to slip it. I've been practicing letting out clutch until right before it's about to engage (which is pretty far, by the way). then I hold it there until I'm ready to launch. when I'm ready to go, I squeeze down on throttle and let up on the...

download free drag sim and you can race gto with the stated mods. sim says 13 flat for gto and 13.3 for gt. you'll need gears and drag radials to beat the gto from a dig--which you can add in the sim. btw, you'll need excel 2003 to run it. http://www.speedshoppro.com/freegateway.htm

tough choice and probably comes down to personal preference. I think the '02 SS has a slight performance advantage stock for stock (~.2 sec in 1/4). and if you plan on modding them both, it may be more economical to mod the SS. I keep hearing that 05+ performance bolt ons are more expensive than...

good info cat. might also check the gear calculator link which allows you to change gears, tire specifics, wheel size and rpm and automatically see the speed. www.speedshoppro.com/

hard to say. taller tires reduce gear ratio but improve hooking. theoretically you could see big improvemetns with a taller tire if you can get better short times.

I want to run an experiment to see which physical factors most help 60’ times. I have a hypothesis that tire diameter plays a much bigger role than people think. Basically I want to get a lot of data from you guys, and then run a multiple linear regression (sorry Ima geek) to see...

just to give you a $ range, my SSR GT10 18" cost me 4K when wrapped with kuhmo's on front and bfg DR's on back. ouch! so wheels alone were probly about 550-600 per. and they weigh 25#, not 18! you can get to 18# but probably not unless you go multi-piece forged wheels. that'll be pricey...

your top speed is power limited (due to aero drag) not gear limited. without boosting your power dramatically, lengthening 5th will REDUCE your top speed not increase it. it's because force to the wheel is a product of engine torque and overall gear ratio. at 550rwhp you'd max at 187 at...

thanks for the feedback! If you have suggestions for other mod's and cars, let me know. on the mustang times, two things to keep in mind. one, the model is based on real chasis dyno curves for each mod (no rule of thumb estimators). two, the model assumes an expert driver (perfect launch...

Some of you may know from my posts on other forums that my buddy and I have been working on a drag race simulator. Well, it’s finally up and running. www.speedshopPRO.com Check out the video tutorial to see how it works. You can download the free version that let’s you race the stock...

my procharger was originally making 525 at the wheel. now I didn't ask for that. Actually I asked my tuner to get me to mid 400s' cause that's what I heard the max safe limit was for the stock bottom end. I drove it at 525 for a few weeks. man, it was a beast. but I was having A LOT of...
