Re: car is boosted, but not moving at all under 8psi HELPPP
i am but i wound't know how much, to compensate the milled head...
i mean even with the head slightly milled, and timing done right
car idles fine, and everything.
i was also thinking that it could possibly be a bent valve, i was adjusting my vavles to the crower cam spec again.. and on 2 of the vavles... they were too tight at all time. i tried playing with it, but they were not moving much.

Re: car is boosted, but not moving at all under 8psi HELPPP
here's what i did today..
i did a compression test COLD, i got 171, 170, 164, 170 across
compression seems to look good while cold..
so then i finally decided to swap to stock oem ls cams, and adjusted the vavle to stock oem spec
drove it around, and it was the same, no difference.
did another compression test after swap cams, and drving it a bit i got 185 across again
i dont know what it could be

ok so you advance the cams not the dizzy? if so how much? did you just just advance 2 degrees or till it knocked? have you thrown a wideband on there or checked the plugs? if you did this stuff then i am stumped

Re: car is boosted, but not moving at all under 8psi HELPPP
yes when i had the stage 2 cams in there, i advance the exhaust cams 2 degrees and retarded the intake cam 2 degrees.. even 4 degrees on each. made no difference, yes ive checked the plugs.. i did a few 5th gear pull on the freeway (since i have a b16 tranny) and checked the plugs afterwards, and plugs looks good. yes i have street tuned it with a wideband, and my friend that tuned it was stunned.. we got the rigth A/F ratior we wanted before boost, and during boost. i check the compression often, to see what numbers i read (they look perfect). nothing has changed. played with the timing on the distributor, nothing has changed... ive tried everything you guys told me and even more.
then the next thing i did was slapped on the stock cams, since i thought it would possibly make a difference since id idnt get ont he dyno. nothing, still the same
i slapped on the stock cams and had the stock timing done. street tuned it again, and still did not pull.
car is reliable as hell, no CEL, never stalled out, no wierd noises, never over heated, air fuel aratio looks to be exactly what i wanted it to be on a wideband...
i drive about 30mins straigth to school and back to school everyday.. (staying out of boost, since my car isnt really boosted)
i even drove an hour back and fourth trips, nothing,... i talked to eveyone i knew locally to see if they could help, they had the same responses here and etc.
im stunned myself, i dont want to up the boost when i already have seen proven numbers ppl are making at the wheels with just 8psi or even less even though its a SC61
i really dont know what i could do next, enstead of buying some oem ls headers and going back to all motor again...
