Whats the limit of a SPS 62, were putting one on my buddies truck. Anyone have dyno numbers or timeslips for this turbo?

 

My guess would be 500-550? My 64 is rated at 575-625.....

 

Manufactures ratings are like snake oil cures...worthless

 

I did low 500's with a SPS62 and crazy larry on my CR i used to have. Got to 530hp when i stacked TST and it was getting warm. At that point it started blowing past the wastegate and sounded like it was pumping its heart out. I have a friend in Colorado that did 560hp with his but he was also blowing past the wastegate and heard funny noises. 500-525 is a good area for that turbo, any more and you'll need more air.

That may sound funny since guys are hitting the 500 mark with stock turbos these days, but im sharing what I found from my own experience. Personally I don't see how you can get to 500 on a stock turbo without being at its extreme limits. The perfect tuning may get you there, but you really need a turbo upgrade at that point.

looking back on it, i should have gone to atleast a 64/14/71 for what i wanted to do with the truck.

 

Hence 500-550......anything above is pushin it

 

Probably the 15-20% correction factors I keep seeing people use. 500X.85=425. My buddy is looking for right around that power range for his daily driver. Sounds like thats what we will probably go with. Hell be running without sticks for a while so I dont want him to get a 64. Maybe I can get him to get both at once...
