500 Hp at the crank build...

[Steve V]

Okay guys,I am looking for what parts would you recomend to get the 200 live at 500 HP. I built a mild one and it lasted about 1300-1400 miles. It had:

.570 boost valve
10 vein rotor
rev kit
stronger PR spring
Alto Band
Teflon rings
roller ized low roller support
CK plate
BR servo
Stock frictions
And no extra clutches

PTC 3000,no WOT lock ups,no billet parts used

The unit was not built for 500 HP. Motor was built after the trans and it just kind of went wild:biggrin:. In hide site maybe I should've dual feed,extra clutches,alto frictions etc...

Hopefully I will get it back to see what failed in the next few weeks. All I know is that my customer says it lost reverse and makes a funny sound. Sounds like the apply ring in LO/Rev popped out and the piston overstroked hence no reverse. Or snap ring came out...

We also had no installed the trans cooler yet,and I believe this was a bad move also in hind site. The car made 438HP at the rear wheels on the dyno untuned running lean.

Get rid of the .570 boost valve, they are nothing but trouble IME.

Buy one of Chris's .555 boost valves or the standard .500 boost valve.
You'll want a billet forward drum, deep pan, dual feed the 3rds, and I would use a billet servo. Retain the cushion spring.

I use the wide band, but 7 stock tan clutches in the direct will work fine, do the 3 clutch OD, it's too easy to skimp on.

What's the problem with the .570? I was getting about 275 @max TV with one in my personal GN. Only a low 12 sec car.

I get 275 psi with a .500 boost valve... It's $4.

Every .570 I've ever dealt with had ****ty machining and would stick.

IMO the sleeve also gets too thin.
