ok i finally finished up my car and took it the the track. only thing is im very dissapointed with my time but i cant figure out whats holding it back.

setup is as follows:

91 crx si
b18c1
b16 tranny
skunk2 IM
3" intake tube to stock airbox with k&n filter
dc 4-2-1 header
thermal exhaust
chipped p28 (5300 vtec 8600 rev)
jimfab bar

tires were falken azenis (195/60/14) at 25psi. i know the azenis arent a drag tire but this isnt a drag car either. i really just went to the strip for fun.

the best out of 6 runs:

r/t .789
60' 2.303
330 6.394
1/8 9.734
mph 75.10
1000 12.555
1/4 14.944
mph 95.01

its not the driver. i had 6 runs, and this was the absolute best i could pull out, i even got a 2.2 60' on one run. i was shifting at 8000. i dont know whats wrong. pretty much everything in my setup is new. new dizzy, new plugs and wires, new fuel filter, suspension is new and has pretty much no wear on it, clutch is new. i mean i know the azenis are hurting me and causing me to lose some time, but even despite that i should be faster then this. i year ago my best was 15.0 and that was with a terrible setup(stock IM, stock ecu, ls trans, stock exhaust manifold, crappy shot suspension, no traction bar). but after it was stolen and i rebuilt it to better then it was im still no faster? whats the deal? the car runs and idles perfectly. last time i checked compression it was fine at 210, 225, 225, 215. no check engine lights. no warning lights of any kind. something is causing me to lose power, but i cant think of anything that would cause me to lose power without throwing a code or showing some signs of the engine not running properly. any ideas?

the only thing i can think of is that my timing is somehow way off (i didnt check it since last time i set timing a few months ago), or the compression recently took a dump. i will check both this weekend

 

That is not very good for a b18c1 in a crx. Not to rub it in but for comparison I ran a 14.8@94 in my 91 b16a sedan. I would check compression, leakdown test, and also check both cam and ignition timing. Who chipped the ecu?

 

i know its not good. and i know its b16 times im running. im just so pissed that i spent so much time and money rebuilding this thing and making it faster only for it to not get any faster. i got the chipped ecu from a guy on here. his chip isnt the problem. the car feels perfect when driving. and another guy on here droppedcrx si made 178/130 with one of his chips on a gsr. i just dont know what could be robbing power without showing any signs that something is wrong.

 

try using a stock ecu for a gsr.

 

i did on one of the runs. 14.95. no change. and with my setup a stock gsr ecu isnt ideal anyway, because of the low vtec engagement at 4400. that why i switched to the chipped p28 with higher vtec point

 

Hmm, does it feel alot faster than 14.9?? I pulled 14.6 (2.3 60-foot) with shitty tires fully inflated on my B16 crx, and 14.2 with 555R drag radials. Maybe it could be track accuracy, thats why i asked if it felt faster... I dunno tho, tough question...hope you figure sumthin out soon

I was just wondering because i have actually seen some crappy ecu chips out there. What rpm were you launching at? Was it bogging or spinning off the line? The timing would be the first thing Iwould check since it is easy.

 

yea those are kinda slow but i was pulling 14.1's with 95&96 mph traps but i was getting 2.1 60's with 195-60-14 falken azenis on 24 psi so maybe you just need to get a better launch.

 

i think its more then the launch. i didnt really launch at any rpm, i just went off idle. if i tried launching at any kind of rpm it just peeled.

 

Possibly a blockage in the exhaust system? You're not running a catalytic converter are you?

 

Also, launching off idle is a sure fire way to go slow. The key is to let it sit at around 3k~ and go, letting the tires spin a bit and hook before giving it full throttle.

EDIT: Just noticed your 60' times. 2.303 is not bad for street tires, but you may be able to do better with a better launch.

 

traction into 2nd and 3rd. and track conditions. or you shift to damn slow wear them syncros out a bit

 

btw if you raced this weekend like i did.. i think every honda owner in the MD/NJ/PA area was running shitty times.

i ran 14.1@100mph about 1.5 months ago and this weekend i couldnt run faster than 15.2@95mph at a track that 2 hours away. i usually go to local maple grove.

 

i dont know. launching off idle seemed best. any time you spin the tires you are losing time. traction into third was fine. but i spun a little into 2nd. i didnt think i was shifting slow. and i raced at capital raceway near DC. i cant help but think something is wrong though. my 60 foots werent that bad. and the car runs perfect. is there anything that can make the car run slow without showing any signs that something is wrong?

 

after looking at my slip and your posted time.

your 60' and 330' sucks.. which is basically launching and 2nd gear. i think traction is your problem.

you may be shifting too late or too early outta 3rd. your top end isn't good. im just going by your #s

 

yea looking at my numbers i was thinking the top end was pretty bad too. i mean at the 1/8 i was at 75 mph, but only pulled another 20 mph in another 1/8. and the 60's arent that bad considering what tires i was using. azenis completely blow *** for drag. 2.3 isnt that bad for street tires in general. i did manage to get a 2.2 on one run but it wanst my fastest run.

 

I have a pretty similar setup, but I know my times were because of my driving skills (or lack thereof )

Your traps seem really low. I ran a 15.2, but at 101.5 mph. I couldnt get traction to save my life. Launching at about 3500 or so on falken ziex's.

 

what tranny are you using? jdm or usdm motor? what trim is your crx? my traps are low. but are on point with my times. you should probably be in the high 13's with that kind of trap, provided you get traction

 

falken azenis arent that bad for drag racing i had mine at 24 psi and pulled a 2.15 60' and when i think about launching i would rather spin then bogyou can def cut those times to a mid to low 14 with those traps but i still think the gsr should pull harder.

 

oh yea and i dont think your traps are on point with your times either notice i have 1 mph on you but 8 tenths in the time.

 

your car is also way lighter then mine. you have a 89 HF, i have a 91 si. im probably a good 2-300 lbs heavier. gearing has differences and causes a lot of differences in trap speed too.

 

video on the below slip me missing 3rd: http://www.psulpac.org/gallery...os=27



the parts covered by hosting site
1/4... 15.2
mph... 95.42

my 95 and his 97mph is the same you ran. but the turbo del sol couldnt get traction due to stock wheels and suspension. and same for me wheels/tires. track conditions werent the best either.

 

your problems look to be your 60'. 2.4 and 2.5 are really bad, lol

i think its good for bad oil pressure in head/**** tires/ and bad 3rd gear syncro

i have a jdm s1 trans and **** LeMans all season 185/70/13s i was chriping all the way up to 4th gear even.

and if you compare, your 60' is bad and your 3rd 4th gear area is bad.

It's a USDM motor, with a 92 GSR YS1 tranny, No LSD. It's in a 1990 DX CRX. Full interior.
