The ATP's are still well within their comfort zone being in the low to mid 20 psi ranges.SHOdded said:I would actually drop to the 8-10 psi range with the ATPs and work up from there. Yes, 8-10 psi is OEM boost zone LOL.

EcoPowerParts said:After all I've seen over the past few years to me the CHRA is the best solution long term for a stock block SHO and someone who doesn't want to build the bottom end. The ATP's add around 500RPM of lag while the CHRA/upgraded billet wheels don't. The ATP's can easily take out a short block after about 6 months when you think you're good and then all of a sudden you're not. The CHRA are maxed around 480WHP on race gas and within the comfort zone of the stock block and even more importantly transmission which has no upgrades available.
These are my opinions after selling and participating in many builds of the ATP and CHRA to compare now. The biggest thing is no matter what there's no solution for the transmission unfortunately and TQ takes it out quickly, weeks on the Flex due to additional weight and months on the SHO.
Nothing like replacing the trans every 6-8 months...
No I highly suggest a tune, they spool faster and make more boost.stealbluesho said:EcoPowerParts said:After all I've seen over the past few years to me the CHRA is the best solution long term for a stock block SHO and someone who doesn't want to build the bottom end.

That is my concern with the ATPs... which is why I would want a dialed in dyno tune.
The CHRA’s can be dropped in without modifying your tune correct? And how long are your CHRAs lasting?

If so do you know at what boost level they move out of that zone?
No idea, just knew a made more power and more boostFoMoCoSHO said:Mike, does the efficiency island change?

My "record" times of 12.4 (12.3 75 shot) in the Flex turbo only (5800ft DA) was on the upgraded stockers, not with ATP's.
I'm going to say again for the record, in better air that would have been the first 11 second transverse vehicle as well as the first to make 600HP![]()

Dang what track was that? Not too many people that feel the pain of terrible DA like i do up here. 5800ft is as good as it gets for me :boom:
