1.5 Roller Rockers

[dgoodhue]

I have been thinking about adding 1.5RR's when I goto do my valve seals in the next few weeks. I have two questions.

Will the 1.5RR or 1.52RR affect my drivability because of slightly addition lift that my truck will have (the stock stamped steel 1.5's are usually 1.45:1-1.48:1) Therefore I will have a little more air flow which inturn will change the MAP calibration in the ultimate.

Will the 1.5RR kick me out of the stock turbo class at syty meets?

BTW my truck is mostly stock with the recommended mods & ultimate and I will be adding a high flow cat & exhuast and auxilary IC in the coming weeks.

technically 1.5 is stock so no I wouldnt kick you out. Id put 1.6's on there and keep it to yourself. the change is very small and the ultimate has the ability to compensate. it's on the rich side anyway.

In that case maybe I'll put on a set of L35's and "keep it to myself" :wink:

Even with 1.6RR's you'd still be in the stock turbo class. You just couldn't compete in the stock class. Which even with the Ultimate you couldn't do that.
