the 5SFTE that pressure2 did gets 1/4 mile in mid 13s....a 1994 corvette LT-1, w/ 300hp 340tq, (auto) get 14.1's? pressure2 has 235hp and 274 tq i think, and he would beat the vette...how is that possible?? theres a huge power difference and i just dont understand...

its just a question i had and im wanderin the logical answer to this....B/c my dad has a 94 LT1 vette (stick) so he would run 13's, and i wanted to race him as soon as im done doin the same thing pressure2 did...

if you can explain this to me any one then thank you

Lots of factors:
* Peak HP doesn't mean ANYTHING. What's more critical in ANY racing (and especially during acceleration in 1/4 mile) is: "What percentage of the time is the vehicle running in it's power band?". If you have a car that has 500 peak HP, and is in it's power band 15% of the race, and I have a comparable vehicle (in weight) that has 300 peak HP, but I'm in my power band 60% of the race, who's going to win?
* Gearing & knowing when to shift is SUPER important in 1/4 mile for the same reason as above. One of the reasons VW bugs are so capable on the 1/4 mile is not just their weight - their gear boxes are damn near perfect for keeping the vehicle in it's power band during most the race. Sure, they may only get 100 HP to the wheel, but it's keeping 80 - 100 of that HP to the wheel the whole way down.
* Driver skill - in the 1/4 mile, it takes more than stomping on the gas to win.
* Is the Vette worn out? A 94 is 13 years old.
* Reaction time, reaction time, reaction time - some people are just SLOW off the line.
* Weight is also VERY critical in the 1/4 mile. Even the weight difference of the drivers (sometimes 50-100lbs) will make a big difference. Let alone the weight of fuel... 1/4 tank, 1/2 tank, full tank. Rotational weight - running aftermarket or HEAVY tires? Vettes have a lot of rotational weight in their tires, they're designed to keep the power to the ground during autoX like racing.

^^^ Just a few things to think about. There's more... but my brain's not working this morning.
