I went to the track yesterday. It was 100+ degrees. I couldn’t get any decent 60fts. My best time was a [email protected] mph with a 60ft of 2.085.

How is my time and does it seem normal. I though with my shifting skills that I would land a low 12sec at least. Thank you.

My mods:
6-speed
Apexi Power FC Standalone/ still on MAF
HKS Exhaust Titanium
HKS Intake
Greddy 4 row Intercooler
Down Pipe 3 1/2 inch
MBC set at 18-19psi
Race Gas

What track and I take it the temps were high and so was humidity?

Your mph seems low for your mods.............

100 degree ambient temperatures are going to affect your numbers, A LOT !
Easily by as much as half a second from crisp cool days.

Hell it was 95 degrees outside and 90%+ humidity~! I bet if it were in the 50-60s you would have ran a 12 flat or even a high 11.

4row on stock twins will take a little while longer to fill up with compressed air, also on street tires dont expect anything faster than 1.9 or 1.8 60' at best. Practice!

Thank you all for your feedback. It was MIR track in MD.

Val, this was on Sunday. It was so so hot...

You're right Val, the traps are a bit low even for hot
and humid. But this is his first time with this car at
a track. With some more seat time he will see 117-118mph
traps even in bad weather at MIR. Remember that NOPI
race there a few years ago we were at? It was 102 degrees
and felt like 114 degrees with the humidity. With 100 octane
I was still 117-119mph traps in the old BPU 6 speed. I think
his 12.6 on street tires is damn good for first time racing the
car.
7thSign,
Put some drag radials on that car and run in better weather.
I bet you see some big improvements. That 12.61 is very good
for street tires and crap weather. You will notice higher trap
speeds as you get a better feel for running the car. Optimizing
shift points can gain 2-3mph. Congrats!

This damn weather is murder on supras!!!!! Fuck It!!! <argh>

George: Did you pull the headlight on the runs, I gained about 2mph just by doing that on my car, too bad I can't do it anymore?

Heck just wait till a nice coool 70 degree day and let her rip......you'll def be alot faster!!!!

Thank you everyone,

Val, I wanted to remove the light but didnt, I should have. I will do what you said and wait for a nice cool day and maybe some better tires.

Cool, I wouldn't risk running Drag Radials because you can easily twist the driveshaft or shatter the rear end then you'll be SOL at the track w/o a trailer. If your really into drag racing then i'd suggest you buy some Et Streets w/RX7 Wheels and some type of skinnies and then go all out.....

Good Luck!!!!

No.

Get drag radials.

Definitely do not do drag radials on a 6sp car. If you want to increase the chances of twisting the driveshaft or shatter the differential, then get them. Drag radials have stiff sidewalls and a sticky compound which is a bad combination for 6sp speed cars at the drag strip. Auto cars can get away with drag radials because their drivetrain is already pre-loaded somewhat. If you still want to take try the drag radial route, slip the clutch out of the hole or you'll be towing the car back home after a few passes.

 

[Blizzz]

Definitely pull the headlight. It also got me about 2 mph.

I don't know what to say about drag radials. They helped me alot and I haven't had any problems with them. So I would say go for them, unless you don't have an upgraded clutch. The stocker will probably take a pretty good beating.

 

[Project-SupraDupra]

pretty good time
it could be faster if it wasnt so hot
aim for around 12.00

And the tow is easily $300+ from MIR to Fairfax..... that will cover the cost of a good set of et streets
