car is a 2002 Z28.street use only.mods-347 forged short block 1cc valvecuts,(pistons setup to make 10.5 to 1 comp. with stock heads)mild ported heads with 2.02-1.60 valves,shaved .030 comp 918's,F4 Futural Motorsports cam 226-226 575-575@114+2(I've had nothing but bad luck with this cam)Yank ST3500,342's 90 hp dry shot followed with a TNT 150 shot, timing tuner,walbro intank.This cam I have now makes decent power up top,but I'd like to make more power and torque from 2500 rpm's to about 6000 rpm's.Also would like to keep the 918's.Any help would be appreciated.Let me know if there's any questions. Jim.

 

the tr224 .563/.563 114 and on the 112 make great mid range power. peak is about 6300 i believe. you can keep your 918's to. not sure how good it is with the spray but i know a few guys who run this cam with the juice and they havent had any problems.

what kinda issues were you having with the F4 cam?

 

My vote is for the TR224 112 LSA, Its a great all around cam. If you wanted a little larger you could always go with the TR 230. I think you will be able to keep the 918s with the TR224 but not sure about the TR230. Good Luck man sounds like you have a nice setup.

 

Run a custom using XE-R lobes. 224/222 .581/581. I have a custom 220/220 reverse split that really runs well. See below.

 

how is 220/220 revers split, thats a symmetrical grind. plus if he sprays alot a traditional split would be better then a reverse split

 

Power and torque at 2500??Your sig say's st3500 stall?I would guess the converter is slipping at 2500 causing a sluggish feel.I would suggest the TSP 231/237 for your setup with Nitrous.
