All those mods on a stock cam and street tires? I would think that without the cam the head and intake work would be wasted potential. I'd bet if you slapped a decent cam in there and some sticky tires out back you'd have a totally different beast. Might want to invest in some gears as well.

don't dump the clutch, you have to ease into it. Get that 60ft time down, with some practice you should be able to get 2.0 60's and that should net you about .50 sec. With the car in my sig I went 13.60's on a 2.0 60ft while running the worst 245-40-18's that money can buy and that was before the headers

OK, I put a panhard bar on the car, and ran mickey's this times so I was not spinning off the line anymore. I kept running a 13.8, with a 2.6 60ft. Where should I be holding the rpms for launch, I kept it around 2000 to 2300 and I kept bogging out badly at launch.

Practice practice practice. Once you get that 60' down you'll be deep into the 13's. I'm not really sure how it's possible to get a 2.6 60' on MT's. And that's coming from someone that's best 60' (I've been to the track like 3 times in my life) is a 2.2-2.3 on Sumitomo 315's

See you droped your 60ft and your time came down. Now keep on doing it.

I dont want to tell you to race on the streets but try to get off the line quick at stoplights, when you can!!!.
I used to punch it half way and than wait a sec before i would go WOT. You need to try a mess around to see what works best for you.

a 2.2 60ft should net you a 13.3 or so.


what was your trap speed on the 13.8 run??

Like everyone has said ''it's tricky and takes practice''. If you are bogging then you need to raise the rpms a little at a time 'till it doesn't bog anymore. With traction and a manual trans you need just a tiny bit of wheel spin when you launch.

don't dump the clutch. I was pulling 1.99 and 2.0 with my car just easing the clutch out on the launch. I kind of roll into the throttle and out of the clutch at the same time. I hold mine up around 2 to 2500 and roll out.

If you want to dump you'll need to raise your rpm up a little more.. probably around 3 to 4k I would think. You're trying to move a heavy car remember

I trapped in at 103, i have a video of me racing where you can see how badly i bogged, the car stopped dead for a second.

when you run sticky tires you will have to deal with the bog you ll get sometimes. But the fact that you trapped 103 from 98 is a 5mph gain. Now things look more like they should.

Did you tune up the car?

Have you been on a dyno to see HP/TQ curves?

Aside that all you need is practice. Search for launch techniques, this site has stuff going back a long time.

I think he has some problem though. Whether it be a tune up problem or not. With his mods, he's running trap speeds that people have surpassed with a CAI and a muffler delete easily. There's something wrong, or he's just shifting too early.

I've been shifting around 5500 to 6000.... Is it possible my heads are actually hurting me rather than helping since I'm on a stock cam?

Could just need some practice. I doubt the heads are hurting you... but I guess it depends on what was done to them. I'm an A4 guy, but I would recommend shifting no lower than 6000. 5500 is too low on a 100% bone stock motor, let alone yours.

And maybe I missed it, but why are you running a stock cam in an engine built for 10-11 second passes?

Agreed. I shift at 6200, right at the rev limiter. Mine's an LS1 so it's a little different, but run that thing up as high as you're willing.

My LT1 with just headers, short throw shifter, and a K&N was trapping 100-101 and running consistent 13.5-13.6 times. I suspect there is something wrong with your car and my first wild guess is that your valves are not properly set. I say this because one time I had a buddy adjust mine and my car went consistently slower by full half second than it did before with no warning signs except for a lack of power...

the first motor I built I ended up destroying because the cam got to my head from the first time I started it up so i broke in this motor with a stock one

as for the valves I'm getting a new cam in a few weeks so I'll be redoing them soon
