more boost = same trap speed?.....FIXED....11's inside
 

went to track today w/ some slicks, used the pre-loading technique(which worked very well once i got it down). there was hardly anyone at the strip and i got to make 20 passes, which was a nice change from the ricer fri and sat nights of getting 4-5 passes all night.

here's the problem, i've gone from 12-13psi to 20-21psi and haven't really picked up any trap speed

old best w/ 225/50/15 BFG's.........................12.62 @ 113 @ 12-13psi.........2.1 60'
today's best w/ 22x8x15 slicks.......................12.40 @ 115 @ 20-21psi.........1.86 60'

recently i've changed cams, got gm 3bar working, and pulled some timing from the higher boost areas. street tuned w/ WBo2, bre, ostrich.....approx 11.0 AFR's @ 20-21psi. feels good, pulls ok, but the butt dyno is telling me i fail............i really need some dyno time for fine tuning.

brief rundown:
crx hf 2180lbs w/ me in it
y8 bottom/z6 head/y8 int.......scat, wiseco, bisi 1.2 cam
t3/t4b turbonetics h-trim compressor, 3" turbo back, no cat or muff..........MI emissions testing FTW
walbro 255, dsm 450's...........maybe time to swap in the bigger inj???........not leaning out so i wouldn't think so

maybe i just suck at cars and need a "pro" to tune it for me

Re: more boost = same trap speed?
 

you answered your own ?

Re: more boost = same trap speed?
 

how hot are the IAT's getting?

Re: more boost = same trap speed?
 

not sure, can this data be monitored w/ a datalogger? running OBD0 stilll, what can be done to check it? resistance check after a pass?

Re: more boost = same trap speed?
 

Have you ruled out the obvious like suspension/driving/clutch?

Re: more boost = same trap speed?
 

suspension should be ok, i run omni power drag rears, DZ/tokico blues up front, every bushing is energy/prothane, jimfab tracbars, alignment is in check, clutch is brand new as of 1-2 months ago, not slipping or at least doesn't feel like it

im sure my driving could be somewhat better, maybe faster gear shifts, ran pretty consistent 12.4-12.6 all day.

to 88dx.........maybe IC is too small?......i always check it after a pass and it feels cool on the outlet side.....idk

Re: more boost = same trap speed?
 

bigger slicks :)

Re: more boost = same trap speed?
 

i know that.........in the plans for next season

why trap speeds not getting any better w/ more boost?..........thats the real question

Re: more boost = same trap speed?
 

how much are you spinning off the line what do your 60ft times look like on low boost and high boost

Re: more boost = same trap speed?
 

60' times are listed at the top, low and high psi

spins like crazy w/ BFG's, lots of throttle feathering

hardly any spin off the line w/ slicks and preload, felt good, best launches i think my car has ever seen





why do my traps suck??? even spinning off the line i should see an increase w/ more power.......right??
