i went to the track for the first time ever. i've never street raced from a solid stop or a rolling start so i didn't know what the ---- i was doing on my first run. best run, the last run was a 14.75. this is with a boosted 99'si, t3 .60trim at 11psi. dynod' at 246 hp 202 tq.pitiful but high trap speeds. does lower tire pressure make a good difference in street tires? what do you guys recomend for tire pressure?

this was on street tires, some champiros i got a good deal on they still had 70%thread in the front 50%thread in the back. my last run i put the front tire pressure down to 35psi. max psi on the tire says 44psi. i should've gone 25psi. i stil had fun even though i had some major traction problems. anybody know where i can get drag radials at a good price?

2nd

3rd run was against a mazda 6 stock which was i whooped dirty sorry no pics i wasn't taking the pics.
here i'm on the first run grinding 2nd after peeling out all through 1st almost...sucks

at the line

Damn those are high 60ft... did you lube your tires with mobil-1 before each run?

robs99si

you think i'll run better w/lower tire psi? i got champiros
tires"cheapiros" they're good for street but on the track they sucked. i'll be getting some bfgoodrich drag radials soon. think lower tire pressure will make a difference in the champiros?

A 14.75 run at 104.6 MPH



At that speed you should be well into the low to mid 13's. What's up with these times?

robs99si

shitty tires and lack of race experience i've only raced last night. i'll be going again to the track soon though.
you think i can get low 13s' on these same tires w/lower air pressure?

djfob

Will some practice I bet you will hit 14 flat with the cheapo tires. Lowering the pressure will help but it won't be too noticable with those tires. Did you drive through the water?

wow a 2.7 60 foot.... you dumping the clutch @ redline or something?

robs99si

no i rev to 3000rpm and then i drop the clutch feathering it out just a little. how do you think i should do it?

87na_rx7

i dunno, i only have raced rwd cars.. its a lil easier then with a fwd car

robs99si

then is there anybody here that can give me some advice on how to race down the track real good? especialy on the launching part. and if lowering my tire psi will make a noticable difference. i felt like going home after my first run of 16.7.lol i stayed though and i stil had a fun time there. crap there are some fast freakin cars there.
