I'm trying to get my times down...

so far my best run on the track was a 16.4 at 86 with a 2.4 60' time


I think I can get that down a little bit

also trying to figure this out cause there is a race this friday


will take advice from anyone but please trying to get more info from the 86-89 N/A guys w/o a lsd

 

what are you doing now? Is your car stock?

our cars do not have enough torque, so your best bet is to rev her up pretty high and not let the rpms ever get low.

there are several methods -
1. rev to 6K, drop clutch (not a good method, things tend to break)
2. rev to 6K and feather clutch to get going, then drop the clutch(also not a good method, clutches do not last very long)
3. rev to 3K and drop clutch(works well) - less wheel-spin is better
4. rev to 3.5-4K and feather clutch to get moving, then drop clutch(works well, but clutches do not last long)

I prefer method #3

My main method, that has got me my best 60' times of 2.3xx is to rev to 4000, then drop the clutch. Yes, you get wheel spin, but if you get enough, your rev's wont drop back below 3800, and you will clear first gear pretty fast.

 

I use method one, but I have a parts car...

 

Method four is the best, rev it till its in the secondaries and baby that **** with finess. The clutch in my car is over a year old and its fine with DAILY multiple launches.

 

i try to do method #3, but with a bit more feathering then just dropping the clutch staight... ihave a TII S5 though...

i notice if i don't feather enough it bogs teh engine.

notice how i said i try? i fail miserably at it every time

 

on my car right now all I have is a bonez filter, replaced the intake tubing with PVC, header and pre-silencer. so not fully stock

most the time I either dump at 3-3.5k or feather... seems like the times for either is the same


when I pulled the 2.4 60´time I dumped the clutch at 5500 rpms... I h ad massive wheel hop though and spun through most of first it seemed


also for a drag launch is it better to have new tires with lots of tread or tires that are a little worn?

 

what where the temps of the trak when you ran the time listend in your sig


I´m curious where I should stand with my car right now.

 

i have a s4 turbo and i reved to 4K and droped the clutch and got a 60 foot time under 2 but i cant remember what it was cause it was my first time ever launching and every one was impressed

 

damn that is a very nice first launch!! My first was a 2.4. On Toyo Proxes FZ4, I launched at about 4 and dropped it. Not a very good 60ft. time, but I'm workin on it

 

4K and feather it out, no dropping got me a 2.0 in my T2, though the model of Rx7 is kinda irrelevant. On street tires I avoid boost in 1st anyway.

 

It was in the lower 90's when I acquired those times. I know there is a 15sec 1/4mi time in her, it just needs to be about 60-70 out when I do it.

 

i rev to 4k and feather...

 

well then I guess I'm not getting into the 15's


but I will try anyway

 

Just dropping the clutch will not get you a good launch unless you have two things:

1) drag slicks or sticky tires that will not spin easily
2) A solid rear axle so you wont get wheel hop

You *may* get an *ok* launch from dropping the clutch at 4k rpms ( I personally just spin the tires and get wheelhop), but probably not. If you rev to 6k rpm and feather the clutch, your most likely going to fry the clutch. Just dropping the clutch is not the way to go with launching these cars. All that is going to do is spin the tires, and tires spinning= car not accelerating. I personally feel that the best way is to hold at about 4k rpm and quickly feather the clutch out. When I launch I get no spin, no wheel hop, and no bogging. Maybe a slight chirp and then Im gone

 

You've stolen my avatar.

Not quite sure what to make of this situation....

Oh well. I need to change mine anyway.

 

hehe....dwarf hampsters with wings are awesome

 

When autocrossing I tend to rev between 4-5k and slip the clutch until I am going then drop it. Anything lower than that bogs my car down.

in my 86 TII I launch at about 6000rpm.

rev drop clutch, get spinning and kind of go sideways but it grips pretty fast and im up at 7500rpm in no time, i won't be able to get some good times until i replace the tranny though, 2nd gear syncro's are gone.

 

Stickgoat - You could always add a body kit and "Type R" sticker to the dwarf hampster to make it look different

 

Next time at the track, I am gonna try slipping the clutch out fast. The last time I tried, my car had almost nothing done to it, and I pulled out of the hole sooooo slow. I think it will be a tad different this time.
