Theres this blue mach 1 in my town thats been reving at me but we've never had a chance to line up. i sound nice, not sure if he has any mods. ashuming that he's stock how would i do against him with my mods?
if he has for example intake, x-pipe and catback how do you think?

 

well with the times ure puttin down im hopping its just eh alt and stuff effecting your car. Stock for stock an ls1 is a little faster dependin of drivers and cond. etc. but if hes got what u got on paper u should beat him. run him and find out

 

You won't beat him running 14 sec. 1/4 mile times at only 98mph...

 

read post above you and look at sig 4200ft above sealevel

 

yea its the altitude, it suxs every thing here is prety much a second slower,
freaken bolt-on z06 run low 13 to high 12s, Ws6 and SS average 14.0-13.8,
my friends bolt-on 04 cobra ran a best of 12.9 before his kenne bell.

 

Ever hear of DA?

 

You might need to find out what he has done.

I do well against LS1s with your mods.

 

I had a Mach 1 rev his engine at every light. I did nothing about it for 5 stop lights. He frustrated me so bad that I finally lined up with him at a long straight away. Can you guess the outcome?




















Yeah I put about 3 carlengths on the guy.

 

i'll try to talk to him and see if we can set up a race

 

i feel you're pain 00formLs1, i'm in el taco, err el paso and since cruces is just a hop, skip and a jump away i also had similar times.

there's a few mach 1's around here as well, never have had a chance to line up with one though.

just run him and see how you do...

 

drivers race

 

ya i will, i just got my pacesetters and tsp ory in today and will be putin them in first thing in the morning

 

I've heard of it, but don't really know what it/you mean by saying "DA". Care to elaberate or point to a link explaining ?

 

i have a real good friend with a mach 1, hes got a couple of mods. we race all the time and the best he's ever done is a cars length jump from a dig that i over took by third. launch good and you'll be fine.

 

i raced one last fall, with an intake and a catback, while i had, nittos, headers, full exhaust in the ws6, i put about 2 1/2 lenghts on him. Even if you run 14sec 1/4 mile, dont forget his car will also be a second slower

 

If he's stock & can drive worth a ****, you should edge him out by a bit with the Long Tubes installed (assuming you can drive too).

If he's not stock & can drive, it might be a little bit closer than you'd like...

"DA" stands for "density altitude".

It's basically a calculation that takes:

Altitude
Humidity
Temperature
Barometric Pressure

At a certain location & converts it into the corresponding air density above sea level.

So say you ran at track "A" a month ago, and the conditions were:

535 ft altitude
38% humidity
65 deg
Barometric Pressure 29.9

DA is 1179 ft.

Same track, different day:

535 ft altitude
20% humidity
58 deg
Barometric Pressure 30.56

DA is -87 ft. Which is like racing below sea-level.

So DA can have a HUGE effect on how fast/slow your car runs - even if nothing changes except the weather.

This is why it's (usually) misleading to compare uncorrected ET's and Trap speeds from different parts of the country to one-another.

For example, my uncorrected ET/Trap speed at my local track (where DA is often 1400 - 2000) wouldn't compare very favorably to someone who always runs at a track where the DA averages -700 to -50.

 

thanks.

 

let me set this forum straight....i raced one at the track. with 315 nitto dr's, aluminum driveshaft, intake and exhaust, a 5 speed, he ran 13.16. i know because i asked him what he had done to it. he pulled in front of me out of the hole but he couldnt pull on me after that. without those nittos i would have whopped him

 

Yeah and the look on the guys girlsfriends face in the mach 1 is always priceless when ya beat um.......I love that

 

Theres a guy near Cols OH that has a yellow mach 1, ran 12.6@109 with H pipe, K&N, and Nitto DR's at a crappy track
