Ok now that I got you to open the thread.
as you all know I moved from SM-2 to X Prepared this year in SCCA SoloII. Street Mod was nearly any engine any size as long as it was Porsche. Prepared has a displacement rule of not over 1.4mm Bore increase. Guess that leaves the 96mm pistons back on the shelf. So how do I get more power ot of the racer. I am getting lighter with better wheels and stickier tires etc. Prepared has no limit on Compression ratio, valve size, ingition, induction, exhaust, piston must be metal and that's about it. Engine I was building was going to have 71 stroke 96mm chinese pistons in german cylinders hastings rings, 11lb flywheel, 6 puck solid clutch, 86b 86b +5 cam, 44 IDF's 2.0L ported heads with dual valve springs, Tangerine header. So I guess what I need if it exists is a 1.4mm bigger piston with hiddeous compression. |

Hey Joe,
I guess I'm not sure what you mean by "X prepared". Is it a local indexed prepared class? If so, which index are you going to be running under? EP or FP? Each preapred class has VERY specific allowances as to what you can do to the induction side of the motor. And valves sizes are specified most of the time. With the bigger pistons you mention, I'm guessing that you're going to be building a car under FP (2.0L). Basically, for a competitive motor in a prepared category, you need a full-tilt-boogie race motor. And that, costs $$$$. -Josh2 |
