heres my set up

b18b
ported/polished head/jg mani/camgears/crower stage 2 cams
bottom block is stock with arp rod bolts/10lb flywheel/ 6puck

turbo set up
rev hard mani/sc61// 2.5 downpipe/fmic/ssq/deltagate wastegate
ngk bkr7es11 gapped at 28

440cc's injectors/walbro 255lph/aem fpr/str rail/ aem fuel filter

for some odd reason.. everything is SET UP RIGTH. the first time it took it around the block it felt shitty as hell. boost guage is reading at -20 psi at idle. boost starts to built at around 3400- and full boost at 4700 at 8psi holding steadly to 7ks rpm's. It fells slower than the car as in all motor form.

my friend and i checked everything, no boost leaks/blown chargepipes/ or anything. didnt datalogg it just yet. but car is tunned with uberdata by a friend of mines. at ilde its about 14, and under boost its at 11.8 and retard it just a bit under each pound.

everything is done rigth, what could be wronge?
ive had a T3 on this motor once and it felt REALLY fast at 5psi, and this set up. It fells like crap slower than all motor.

i checked the compression.it reads 185 across, no check engine light what so ever . it blow off perfectly fine and loud. but car is not moving as it should. car doesnt BOGG or anything on me. it drives fine, but car is not moving at all under any boost. You can hear the turbo/bov from blocks aways.

my question is..
What could be wronge? Ive tried everything, and researched everything. In this case. it is not because of a vacumm leak, loose chargepipes, blown head, etc...

 

cam timing ??

 

is your wastegate functioning properly? you didnt say you checked it.

also. by posting pictures. of the setup. people would be better able to help you.

 

You don't get boost if your wastegate isn't functioning moron.

3.8 GPA ehhh? lmao

 

i would say my best guess would be cam timing. but even with the t3 turbo set up, it was boosting with stock timing. i didnt want to mess with it until ig et it on dyno. im just fustrasted
i dont know what it could be

 

how much is it being retarded under boost? and did you put in the new cams and gear after you already boosted or were they in there when before you were boosting 5 psi.

 

how much are you currently boosting? if its 5psi, that might be it, cam timing my be off. not running enough timing could be it. why are people using sc61's to run such low boost?

 

If it hits 8psi making noise and all then it should be ur clutch

 

yep, that's gotta be it! :1

 

sell me your sc61 nig
