I currently have a 83mm benson b18c5 block (9:1 cp's & pauters) w/ stock '97 itr head and ctr cams, as well plenty of fuel (750cc rc's/hondata/walbro255/aem fpr/rail) and a t3/t4 turbonetics .48 exhaust and 60 on the compressor with a sfp manifold and 2 1/2" intake plumbing.
Also my exhaust is a full 3" downpipe to a 3" thermal.
On a mustang dyno the car put out 292 whp @15psi and 331 @ 19psi when i still had my full 2 1/2" downpipe/exhaust.
When I upgraded to the full 3" downpipe + 3" thermal, I got 310whp @15psi and a misfire @ any higher boost kept me from upping the boost. At this rate I figured it would probably take me 25+ psi to hit 400+ hp. I have since changed plugs and wires and regapped (.26) on a 2 step colder plug and the misfire is no longer an issue.
My questions are: 1)will an sc 61 help me achieve 400+whp (on a mustang dyno) without having to boost at crazy psi levels (25psi+)?
2) at the 400hp level are my ctr cams gonna need adjustment (I have skunk cam gears but they are not adjusted)?
3) is an itr intake mani and throttle body limiting my #'s?
4) will my piping/downpipe need much modification going to a sc61 from my t3/t4?
5) will my wife divorce me soon if I keep spending...oh who cares

 

any input would be greatly appreciated...

 

the sc61 will easily produce more power at lower psi.

 

we have the same bore, same benson block, i have 3" downpipe and exhaust. At 8psi on a sc61 made 300...at 10 made 331...i have a dyno chart of 368 forgot what boost that was on..it was before 14 all I know

 

sc61 is a good turbo
but you could always go with this

I have a precision sc-61 and I put down 397WHP at 10psi @ Abacus.

 

thanks to all that have replied...any input on my other questions?

One last bump

 

I used to have a .48 t3/t4 turbo and I upgraded to an SC 61 a year ago.
I have a B18c 81 mm block.
I want a larger turbo now.
