all of my mods are in the sig. i ran a 14.12 with a 1.94 60' @97mph. since then i have added 176 fan switch, pipes in place of cats, and slp1 3/4" headers. does anyone think that i will break 13's now? if so by how much and what mph?

thanks,

David

p.s. i know this is a general and stupid question but all of my friends keep telling me that i will only pick up 1 or 2 tenths but mph will increase a good bit. so im hoping to settle it(at least until i run it again).

 

Under the same conditions, there should be no reason not to break into the 13s.

 

You should be able to hit some 13.8's to 13.9's with that setup if you run under similar conditions.

 

You're close enough to the 13's that it's very possible you'll get a 13 second timeslip. I also agree that you'll gain more MPH than ET. I'd guess that you should get a 100 mph timeslip depending on the conditions.

Personally though, I think your headers are too big. You'd probably see more of an improvement with 1 5/8" headers.

 

i think you will hit the 13s

your already right there..

 

well i took the header size into consideration and after alot of research on the board it seems as if the 1 5/8 would give me more bottom end or torque and the 1 3/4 would give me more top end or horsepower. i thought about it and realized that i already have torque out the @$$ so i decided to go with the 1 3/4.

thanks,
David

 

Top end HP above 6000 maybe. I doubt your TPI spins more than 5500
