Mach1 13.0 runs....tips?

[Skip01]

2 runs a friend of mine got at a test n tune....looking for some tips on gettting a lil better times.

Weight Reduction.

Did you slip the clutch or drop it?

Those times are about right for that trap speed. A 107 trap is good for 12.8s on some shitty slicks. Which is what my friend ran in a 99 GT with 3.73s, SFC's, TB, LTs & Xpipe, pullies, and 22" slicks off a sentra (which numerically raised his FD ratio to probably 4.10s if I had to guess.). He pulled a 1.76 sixty foot on those slicks still spinning.

You should be trapping higher with those mods though. Not sure what is wrong with your car, maybe the tune?

I ran 13.17@103 with a 1.91 sixty foot in my Auto Mach 1 with just an X-pipe, JLT RAI and a 3,600 stall. I now have American Racing Headers 1 3/4" to matching offroad 3" X-pipe and a new built transmission with a 4,200 stall. I put down 300/322 on the dyno Monday. I'm shooting for 12.8 or better.

damn, thats better than me in my mach

i have intake, tune, x-pipe, 4.30 gears, some suspension, ALOT of weight reduction and only go 12.9 at 111mph with a 1.9 60FT..

boost

 

[Skip01]

Thanks for replies, ima respond too most when I get home. Phone lame for typing.

Powershift that bad boy.. But really, he needs to shift faster into third and fourth. Would help out.

 

[Skip01]

Yeh hes talking about weight reduction....but really would like too run 12s full weight first.

Any tips on the launches?

 

[sam92lx]

work on the 60ft....plenty of room for improvement. Play with air pressure and launch points. Are you slipping out of the hole or complete dump?

Dont give up and keep practicing. My WS6 went mid 12s on regular radials at about the same MPH. You get that 60 down and your 330 and you will be going much quicker.

this.. every tenth off your sixty gains you about 2 tenths on the big end so get that thing to hook man! lol drop the PSI in the radials down to around 12 and launch higher and he should have no problems hitting 12's.

Just work on your 60. I ran 13.0 at 107.8 as well leaving at 4500 and spinning all the way through first. Anything below 4k i would bog. I slipped the clutch and i had 275/45/17 mickey thompson et street radials with 18psi. This was my first time ever racing on drag radials and i only got 4 runs that day. My car has an o/r x pipe and a catback that made 290/309 full weight with just lowering springs and bilsteins for suspension.

1.9 sixty sounds like it must have been spinning? Get rid of the radials, and put ET Streets on it. The radial tires have too stiff of a sidewall to take to the shock launch of a stick shift car.

This

 

[bigjohnson4.6gt]

that seems about right, my automatic ran a 13.5 in stock trim and street tires, I got stickies and will be getting a tune come spring

exactly, 15psi.

 

[crystal_SVT]

he should be able to cut at least 1.7's even with the radials. although slicks would be better especially on a stick car i think there is a lot left with what he has there.

 

[blackgtcp]

Im going to run my mach for the first time tomorrow. Im basically all stock with stock tires. You think I should launch at 3300?
