What do thing my red 93 r1 would run in the 1/4 mile with 350 horsepower.

 

Well, other than that if it's pretty much stock...
350 rwhp = high-11s to low-12s
350 flywheel hp = low-to-mid 12s

 

i don't think you can say what you could run from just horse because i have around 300 to the wheels and run 13.3 and my friend has around 550 and runs 13.1 its all the driver really

 

Yeah, there are WAY too many factors, that's just a general figure though that shouldn't be too far off I gave. It really could vary a lot.

 

550 rwhp=13.1 ,, 550 "rwhp" in a properly tuned car I really believe that it is capable of a mid to low 9..
Streetdreamzny, show your friend how to drive...

 

unless its a supra....13.1 @ 125mph or something ridiculous like that

 

Ya show him which pedal is the gas and which is the brake. I mean with 550rwhp you have to TRY to get that slow of a time. Maybe hes trying to make you feel better

 

my friends car is a mustang with a pro 5.0 engine and 14 pound vortech supercharger, also running skinnys + slicks. his 60 ft were good like 1.7 or 1.8 i don't know what his doing wrong - maybe his car is tuned really bad?

 

Oh no hes donig fine. Its the mustang you have to replace.

 

Lol, good one mane.
