Have an old phamspeed kit with a 88mm turbo what kind of power can I expect on 370 inch motor
L92 carb intake
l92 heads
9 to 1
comp cams 224 222 .581 .581 114+2

What a great post.

I'd say exactly 622rwhp. But only 620rwhp if you are using AC Delco spark plugs.

I did 624/678rw with a 70trim on 12lbs with an old phamspeed kit.

It's a good thing he didn't tell us anything else about the engine, because the only thing that makes a difference in power is the maker of the kit, size of the turbo, and the displacement.

Depending on compression ratio, heads, cam choice, fuel system setup and octane the compressor could easily support 800-900RWHP on that setup.

sorry updated

CHRISPY

Couple more questions for you:

Pump or race gas? Meth injection? What exhaust config?

At 15#s boost I would think ~700RWHP will be easily doable with a good exhaust setup on that motor

Race fuel and its also in a Mustang the exhaust is 4 inch into a 3inch dual exhaust with magna flow mufflers

Also have a under dash a2w cooler.

Race gas? I would say 800 easily...

he didnt state if it was the tubular header kit or not.if it wasnt you can still use any factory fitting shorty header like i did.

tubular headers

ddnspider

with what u listed thats what i figured

CHRISPY

Doh! sorry I forgot they made the tubular version too!!

There better than just running reverse shorties?

ddnspider

iTrader: (26)

the tubular phanspeed kit?definitely better than shortys

dmracing

iTrader: (78)

what would tubular be worth power wise as compared to reverse shorties?

ddnspider

honestly,thats rather controversial.people have made 1000rwhp with stock truck manifolds and people can make a crapload with tubular headers.Tubular headers are supposed to be much more efficient but unless your really pushing the setup i dont think you'll see that big of a difference.everyones goal is to make the most hp at the least amount of boost with the lowest backpressure so that that as u will.
