View Full Version : First time at the drag

Took my '92 gt-s to the drag strip yesterday, first time ever.
Didn't do too great, kept messing up the launch. I kept dumping the clutch a little too low. The tires would slip a little, then grip and bog down. I only got 6 runs in before I had to go to work, and only really got 1 good launch, but I had an absolutely terrible reaction time, my worst actually. My last two runs had a .1 reaction (which I guess is ok) but I fouled up the launch.

best slip;

Reaction .6250
60 ft 2.4219
330 ft 6.8881
594 ft 10.130
1/8 time 10.7140
1/8 speed 64.19
1000 ft 13.9151
1/4 time 16.7111
1/4 speed 82.27

That means that if I keep practicing and get a good launch and good reaction, I might be able to hit 16 flat? I'm going back friday with some higher octane fuel and see if I can speed it up a little and become a little more consistent.

Thats not bad at all for your first time! Unless you are bracket racing, don't worry about your reaction time. Take your time and make sure you get a good launch. Get that 60' time down and you'll be set.

Anybody with a 5spd 5sfe know when (if at all) to shift to 4th? I can't decide. I'll just about hit redline in 3rd as I cross the line if I don't shift. I just don't know if taking the time to shift to 4th would pay off or not. I crossed the line in 3rd on the above mentioned slip.

Probably shifting around 5300 or so is the best use of the 5s power band for a 92. By redline it's really not giving you as much grunt so I don't know that it's worth taking up there.

Thanks for the input.
I guess the easiest way to tell is just to get in several runs this friday and try both ways.

Does anybody happen to have a curve graph from a 5sfe, out of curiousity?

From what I've seen on 5s-fe dynos, you would get the most out of the engine by shifting at 5,800-6,000 RPMs.

97+.. or maybe it was 98, anyway, the later 5s, and maybe it's camry only, but.. memory is failing me. In any event, later heads made power higher into the RPM range. Earlier 5s are pretty much done by 5200 and on the way down.

Well done mate, compared to what I got yesterday with a 3S-GE thats very good going! It was my first time too, loved it.

Infact I think I'll put a post up so you can all laugh at me :)

What's the fastest anybody's heard of for a stock 5sfe down the quarter?
I've just got a cone intake and Borla Catback, aside from that it's stock. I doubt either really help at all.

Isnt some of the 5s problem bein too rich at higher rpms. I got a HKS AFR Im gonna try puttin on mine and seein if It can make any difference. I never been to a drag strip in mine but i imagine Id run about the same time. Me and my friend have the quarter mile measured out and i hit about 82 or 83 mph everytime.

I don't think being rich in higher RPMS is an issue.. it's very rich at WOT through all RPMS I think, so there might be a little power to squeeze out of it that way. The higher RPM low power is more due to the head design not being set up for high RPM power. (AFAIK this is due to cam setup and flow limitations)

Yea i know the head design is the definate weak spot but any gains up top would be great for the 5sfe. It sucks bein able to go thru 1-2 so quickly and then just getting progressively slower in the top end with each gear. Im thinkin about the 3s head swap too. Might be a good winter project next year.

I'll try to find my slip again if you guys want proof, but the 93 GT went 15.9xx just BARELY under 16. Trapped at 88mph, essentially a 2.0 flat 60'. Bone stock. Stock airbox. Stock exhaust. Stripped the back.

I don't think mine is the norm. From what i can tell, it was always a bit of a freak. It actually pulled hard as a 5sfe can pull all the way to 6k if i let it.
