I'm ordering my last round of parts for my turbo build and I've heard that the divided Hotside on the gtx series turbos chokes the power in the upper rpm. I have a PFab divided mani and the gtx3582R with a 1.06 divided Hotside. Should I swap that for a normal gt35 1.06 Hotside? I know I'll lose a little on the spool speed, but if it will be a 50hp difference on 93 + meth then I'll sacrifice a little bit of spool. Hoping for 550 on pump and meth and 600+ on ms109. Lets hear your opinions.

 

Top end really doesn't matter much unless you are going to just use the car as a drag car. For the street or track you want more low to mid range power and tq. I would stay with the GTX for it will produce more power throughout the powerband then the gt35.

 

I mean just swapping the Hotside housing. Keeping the gtx compressor wheel and all, but putting a 1.06 undivided Hotside on the divided PFab mani. It wouldn't be truly divided all the way to the compressor, but I am wondering if I would retain 80% of the "quick spooling" characteristics the divided mani with gtx series turbos have, but still have top end power for occasional highway pulls and such.

 

I like doing things different... you should have the divided housing extrude honed to increase its A/R and give it that "perfect flow texture" on the inside.

 

stay with the divided t4 1.06ar hotside. thats one of the best setups out there

 

i agree, seemed to work great for joey

 

True, forgot Joey had a divided gt35. He made 580 on pump and meth before switching to q16/c16 (forgot what he runs). I want to get a reliable, no meth 375ish hp, good fun 550ish street tune for weekends and a 600+ ms109 tune. We'll see if she gets there. Real Street should be tuning it late October I believe.

 

dont do meth, its bad for u
