I went to the drag strip on Saturday for test and tune and could not break into the 13's. 14.1 @ 102 was my best run of the day(although I did it 3 or 4 times) Launching a SC'd Si is a PITA. My 60ft times suck, pretty much 2.3 the whole day. I didn't try the e-brake/pre-launch trick this time around but I'm thinking I can cut 1/2 a second off my time with a good launch.
I have I/H/E SC stg 2(3.3 pulley) all CT-E. I have motor mounts which helped with the wheel-hop but any time I tried to rev and launch it would just spin the tires...
This is only my second time to a drag strip so don't rip on me too much! :)
* many people at the track say it runs a 1/2 second slower then other tracks so I don't feel that bad.

What wheels and tires are you running? 14.1 still isnt that bad man, its a Civic Si !! How many cars run 14.1 and get our gas mileage?

I still have the stock wheels on Kuhmo summer tires. I'm going to get some RPF1's in the next couple of months, 17x8 so I should have some better traction with the wider wheels and tires. To be honest I know a lot of people on here say they still get good gas mileage with the blower but I would guess I'm getting about 18MPG on mostly city driving.

wow..

alot of cars..

the newish toyota camry v6, the ford taurus SHO... a slew of other cars that get high 20s low 30s mpg run in the 14s aswell.

i wasnt aware that a supercharged k20z3 was only capable of pulling 14's..

i ran 13.0s on a 50 shot with crappy tires all day.

do u have much seat time at the drag strip..

with 260-280whp u should be capable of running 13.4-13.3 in that area..

:facepalm:

Read the OP. He says it was his 2nd time at the track. And his track runs slow, in general.

I have no doubt that my car is capable of a mid 13 if driven better. I'd like to think I'm pretty good at shifting but my launch needs a lot of work. I'm going to try using the e-brake and preload next time I go.

I am going to Ocean City for a car show/mini vacation with my friend so I can't. Maybe another time though, thanks. I'm sure you could school me on the launch...

I don't see a 50 shot running 13.0 on crappy tires. I ran 13.5 on a 75 shot with Z1 star Spec 225/45 tires. 50 shots will only net you to 240-250WHP MAX...

Just keep practicing, you'll eventually managae that 13. Lay low on the throttle at start up cause the tires will want to spin.

I was going to mention that..

Cause a few other supercharged Si's that ran at the track with me still managed to trap 106-107 @ about mid 13's, which was on street tires.
It seems low to me too. I noticed OP is running the 3.3" pulley, but I would still think OP should be trapping higher. My trap speeds are right at 106-107 with the 3.15" pulley.

My installer actually ordered my stage 2 kit for me. I forgot to tell him that I wanted the 3.15" pulley. I'm thinking it would only give me about another 10HP anyhow. I'll probably end up swapping it in the near future but honestly I think the biggest problem is my launch. My buddy is editing the video's my GF took so by next week I will post them up. You can see how slow I come off the line. I basically could not rev it at all without spinning the tires.
