There is a dual plug head for one of the 911 Porsches. I think it's the 935 which is the race version of the 930 which is a dual turbo 911 (depending on which version you have). I'm not sure why exactly the dual plug is better?
They're only about 450 under race prep. It was the 917's that were 600 something hp and they are flame throwers also.
My 84 930 was only rated at 285hp stock. I'm right at 400 now with this TT and it is blowing that elbow off under pressure, not stepping off.
The elbow and the intake are both machined to set the clamp against a "curb". I just threw a code for a lean intake. I have to check to see if I split something or the clamp is ready to slip off again.
There is something going on with the elbow under deceleration and we do think it is collapsing the elbow. I need a camera under the hood on the thing.
The 935's are the cars that if you are behind them on the track, as the driver steps off going into the turn, throw about a six foot flame out of the exhaust. You don't want to get too close unless you don't mind singed eye brows.
The problem that I had with the Paxton was based upon engine rpm, it had to be limited to 6,000 rpm otherwise you would toast the fluid. Since it is automatic trans fluid, it would smell like a bad automatic transmission. After 3 rebuilds, it was time to move on to a different solution.
Now the blower in my SVT Contour, stripped the splines off of the input shaft on the blower. The solution was to "update" the blower to the tune of $2,500.
Supercharged cars just have abnormal issues.
I'd rather stay with my 2x4's and my Webers. Those don't snap crankshafts in half.
Incidentally, broken in half 289 cranks is the reason Ford revised the firing order on the 351's. How many broke is anyones guess but for Ford to take notice of an issue means more then just a few.
They can be a bunch of numbnuts. Consider the '68 428cj's running out of oil.
How long was the 428 in production before they noticed that they had a problem?
I'd consider going to a 351 firing order on a supercharged 289/302.
