Last time I took it I kept running 15.0 consistant, with this new setup Im kicking a new 2013 Si by 3 car lengths and a 2011 Mercedes (??) by 2 cars... so I should be in the mid 14s.

Do you have time slips we can look at? You should definitely be quicker than 15.0 even on stock tires.

I need to look for the slips...I was getting 60fts of 2.5

This is where you will need to learn how to slip the clutch on launch. Looks like you're getting WAY too much wheelspin. You would probably cut a better 60' just rolling off the line with a 3k clutch slip..

Yea I got the hang of it already but the track down here sucks ass, I got rock chips on my front bumper and fender so I dont think Ill be going till I get my clear bra installed.

Practice...practice....practice. Great launches come with a lot of practice. Try different tire pressures (no lower than 20-24psi). Are you power shifting?

Your car DEFINITELY has a faster run in it...you just have to coax it out ;)

Thanks... Took some practicing. Getting the perfect launch RPM is the key to a proper 60ft. For me, a good burnout along with a 5.8k rpm launch is the key for it. Tried raising the rpm more, ended with a worse 60ft due to wheel spin.

Check the vid and u will notice how my launch was done:burnrubber:

Btw, my car has 165whp and 132tq

Here is my best 1/4 results first time drag racing my FR-S at Fayetteville Drag Strip in NC. Temperature around the 70's.

Reaction .6924
60FT 2.3735
1/8 72.64
1/4 15.4469
1/4 RPM 91.35

The only thing I removed was the spare tire, had stock tires, Perrin LCP. Nothing else fancy. Launched the car @ 3000RPM without causing any spin issue, no burn outs to warm up tires. I will try to hit 4K, work on my reaction time more, and reduce more weight in the trunk to see what will happen the next time. Hopefully under 15's. Tire pressure I don't know what the best psi would be suitable for 1/4 mile.

First and only run, base tune FBM Base kit, 9psi, automatic, tons of tire spin:

14.9 with 9psi turbo??? you should be running over a second faster. I'd say mid 13's.

you need to practice more:happy0180:

I'm a bit concerned myself, not being new to running ET's. Things I could have improved:

- Base tune (runs rich and less power)
- Turn off TC completely.
- 1/4 tank instead of a full tank.
- I was shifting around 7300, perhaps I should have waited longer.
- Hot tires

I'm a little sad that I came in that slow, I'm really hoping the car is capable of more, even if it is an automatic.

no offence - I don't think the car is the problem. 14.7's have been pulled off by a good driver in a bone stock car.

as I said - I think you need more practice

Edit: just noticed you are in an automatic. stock autos get low 16's I think. in that 14.9 is OK, but with 9psi I would think you would be at least in the low 14's or better. (not much practice needed in an auto where you just mash the throttle)

We will see soon enough. I have another tune file waiting for me from Visconti Tuning.

13.71 @ 106.3 with a full blown base kit at 7.5psi base tune. Stock tires with a 2.3 60ft. At BIR at the maperformance event.
