any dyno numbers also give me your feelings about them?

 

you don't run those cams with turbos..
too much duration

 

Really? Well, the 402's are what Crower lists as turbo cams. The 403's do have a little too much duration, although someone here on HT said that they yielded higher dyno figures using them over stock.

Anywho, I have the 402's and they're real nice. Unfrotunately I can't compare them with stock cams on a turbo LS since I never had the turbo without them. I'm going to the dyno soon so I'll let you know how things turn out.

 

Crower 403 cams kick *** for turbo. I had the 402s before them and it is a huge dfference. i am actually selling my 403s right now to go to 404's so if your interested give me an email. Boosted3g@aol.com

 

how would ctr or itr cams compare to the 402/403's for turbo?

 

Well I don't know jack about an ls motor, but I just tried out the 403's on my turbo'd b16a. Performance on the small cams was okay at best. The problem was with vtec. The duration was so much (256 degrees) to be exact on the intake that once vtec kicked in at 4600 rpm, the car just fell on it's face. It was like hitting a rev limiter. I didn't try using cam gears.. but it just wasn't worth it. Slapped the stock cams in and it's a world of a difference to say the least. I will be in search of true turbo cams soon.
