Big time ..Swap them for gsc 2 cams and expect huge gains..

 

Thats a small turbo to warent the high rev's.

 

OP I don't mean to jack your thread but I just needed a little feedback...does this look like valve float?
The log doesn't show anything out of the ordinary, but the power just dips.
Stock IX turbo, S2's, meth, and the usual boltons.

 

Yep you got it valve float for the win..Get yourself a upgraded valve train..your losing like 50 whp easy,

 

Thanks for the insight guys. I'm pretty excited to get rid of these cams. They have to be magic cause these were touching awdmotorsports 6262 power record with a pretty mild tune but we have a better quality e85 here. And by better quality I mean hand mixed. No pump guessing

 

thought so, thanks for the confirmation...I think I'm gonna go with a set of supertech singles.

 

Wouldnt valve float show up as exh valves hitting the pistons?

 

With s2 go with the dual set they make 2 a 96lb and lower one go with the lower one.

 

Sometimes that will happen in extreme situations.

 

hey whats up if i have the hks 280 cams and brain crower springs can i use the oem retainers with this setup

 

No. The springs should come with retainers.

 

can i use the stock valve springs and retainers with the hks 280's
