badly in need of more turbo. little mp70 has been great, but is out of breath at 605rwhp. will push the 4.8 to around 750rwhp, both of those will easily do that. looking for any experience with them. price is fairly close, more about service and reliability from both companies. I know bw s475 would be cheaper and make the power. fitment just would take a lot more effort. like the smaller frame of the others.

 

I have a pt88 with low miles and minimal track passes on
I'm near Pittsburgh

Either one of those will carry better then the little mp70

I ran a pt88 on a 4.8 many moons ago, with right cam and trans it will fly or bust rods

 

We sell the precision units.
Can't say about tnetics but the
Precision compressor discharge is 3".
it's a blasted aluminum not polished.
And is slightly larger then your current turbo compressor.
Needs a -4 oil feed line -10 drain is fine.

The exhaust is same size and with fit the same area.

 

i'm running a pt7665 billet wheel and made 727 on a 4.8 i didn't have my boost controller set up correctly when i went for a hi boost setting on the dyno, i have no doubts it can make 750-775 where i want to run it the turbonetics turbo i wouldnt have any problems trusting there new 78 or 76 to get that job done either.

 

What psi to make 600 wheel? Any meth?

 

I have also considered the 78/68 turbonetics. smaller exh. journal bearing unit is about half the price, just worried about making over 700rwhp with it.

peak around 16# falling to 14# about 4000rpm

rick shoot me a price on the pt76/75 journal, unpolished unit. I knew the physical size is a little larger on the precision.
