The JWT flywheel is really good. And can hold up to a ton of torque with the right disk. I have the geometry modified on my pp and with sintered iron I've held 400wtq.
You running E85? Every tune I have seen running E85 has shown that there really isn't much power loss running rich like there is with Gasoline. You can run a 10:1 AFR and run really strong, where g...
E85 DOES NOT like running lean. Run more advance, but keep it a little fat. Otherwise you will melt things. E85 relies, in part, on the extra fuel to keep temps down and raise the MON and prevent d...
As far as I can tell, the pintle covers are supposed to help with atomization? I don't think they are required, and I know of several people with the same issue and their cars run just fine.
Looks like the 4b11 guys are having issues with ring gaps being too small running 2bar boost lol. .004"-.008". Ya, too small. The rings supposedly butt ends and cause pistons to crack. Or perhaps p...
Using NA specs is perfectly fine for a boosted motor. Even at .015 and .017 I'm sure you will be just fine unless pushing 30+psi boost. Stock DEs come with tight specs, and although the pistons don...

The puddle I referred to is called the "Tau"? puddle, and is referenced in a lot of tuning books I've read. It has been very difficult to actually piece all of this information together for me. It ...
