sup yall.......ran my car after the dissapointing times last time i posted.......i ran again today and hit 15.598......best out of three runs.........i stll want to know why my trap speed is so low though? i am only at 84-86mph at the most when im done for the quarter mile.....things since last post before the track........i changed both o2's, cap rotor, pcv valve.......plugs and wires i did before.......what else can it be fellahz about my trap speed?!?!?! i should be around 90mph +........thanx

 

what did you run last time?

 

16.8-16.7-16.5-16.2

 

did you get ur car dynoed yet..?

 

At least try a compression test before you throw more parts at an unknown problem. Clogged cats can also really hurt performance.

 

nope no dyno yet, i already did a compression test..190 all across.........cat is still stock 89 si hb 1 1/14 in cat i got 2 1/4 in piping

 

Wow that is rough, I recently ran my friends EG this past Sunday he has a 1st gen b16 with full interior, with just i/e and he is running a gsr p72 ecu and I hit a 15.03 on 13 bald steelies with a 60' of 2.2 and a trap speed of 90.xx, how is your traction and ****, good tires will help A LOT ,my first run in his car was a 15.8 ( bad traction ), next was a 15.5 ( lil better ), then the 15.0. With some good tires I am sure I could bang a 14.8, on the 15.0 run my reaction time was a .894 which is horrible

 

reaction time doesnt make any difference on your et

 

An inch difference is a big diference. Try going with a high-flow cat. That might help a little.

 

adjust your timing to stock (it may be off)

 

Last time I went to the track I hit a 15.5 too. Except my mph was 90.67. Are you sure that cat is not clogged?

 

post ahead the whole numbers on the best timeslip
that way we can tell if u loosing low end power, top end, u missing a gear, or what
its hard to predict whats wrong with ur car by just a ET .....
i have seen a lot of fast cars runnnig slow.. and its drivers fault....
like RSX T-S runing 16, as a CRX B16 and a CRX ZC... and a 00SI on 15.7's///
so just post the timeslip and we can predict where ur loosing power and give u better answer..... IMO dont really take our guessing opinion.... take it to someone that can really look in ur car and knows.... that might give u better answers

 

r/t .613
60ft 2.401
330ft 6.459
1/8ft 9.954
mph 69.71
1000 12.990
1/4 15.598
mph 85.98

 

there it is fellahz........seriously considering b18c1 soon.....very soon

 

Are you sure that your timming isnt off? Some guy had his off by one tooth and he was running 15.8s. This is a rumor, but maybe you have the auto cams?

something is pretty strange with that timeslip........

here is my best time so far:

r/t .317
60ft - 2.49
330ft- 6.5
1/8 - 9.953
mph- 73.32
1000 12.82
1/4- 15.2 @ 93

 

compare that with his............

seems like his gearing is a lil weird......... what trans are you using??? maybe he is shifting way tooo late and not getting any more pull out of his setup.......... try shifting a lil sooner

 

y1 tranny.......hasport shift linkage.......3rd gear slight grind.......

 

car runs clean.....no bog.....no nothing........but i kno it could be runnin better.........idles fine runs fine.......new o2, plugs wires cap rotor....pcv.....the thing that i want to kno is that.....why does it rev up slow from 1-5rpm........the rpm's should jump up quicker.......
