Just installed CTR cams in my lsvtec with chipped P28.
Car is bucking of the line. Check timing 3x & it's dead on. Intake cam advance 4 degree, Exhaust cam retarted 1 degree.
Still adjusting VAFC.
Do I need dyno?

 

Can anyone help?

 

why do you have the cams advanced and retarded for ?

you might have to add more fuel, because with a stock ls vtec its already gonna run lean but then you add ctr cams and get even more air going in, its gonna be runnin ultra lean.

could be your chipped p28 not mixing to well with the vafc, idk just saying.

 

My ITR cams in my lsvtec are TOO small, After the dyno tune my cams were adjusted +4 int and -1 exh.

This was my dyno run last night.

ITR cams are nice for a street setup, not small. you can easily pull 180/190 whp with them.
you prolly need tuning, timing is prolly off in the program.DYNO

 

same problem..except I put it on too loose and it sounded like a water boat with engine problems...thats why I brought it to a shop....leothelowerlip

 

what pistons are you using???

might not be enough compression to get the power you want out of those cams

 

whats the rest of your setup, and what cams DID you have?

will ctr go that high or should i get high lift cams</TD></TR></TABLE>

Man I dont know but 11 grand is a lot on a stock block. Search rod stroke ratio

10:1 c/r B16 pistons.

I had stock B16A cams w/ gears, B16A 10:1 c/r pistons, ported B16A head, Akimoto intake, DC header, Skunk2 catback exh, MSD ignition, Apex'i VAFC, B&M fpr, etc..

 

yeah, you need dyno, your b16 pistons if being 1st gen(pr3) will yield about 11.3/4 compression on a b18a/b block.

 

i would start off with +2 on the intake and +1 on the exhaust. set your timing ignition timing at 17 degrees. fuel pressure should be around 44-46 psi with vacumm on. hope this helps.
