Supercharger set up to 3.9

I agreed. Forced induction needs to be incorporated from the design up. These heads, valvetrains, blocks and sleeves are poor candidiates IMHO

LOL, I'm partially started on the engine, it will have O-ringed and pinned cylinders.

If one isn't going to overpressurize the cylinders, there will still be significant increases in power without overstressing the engine.

The valve train will see limited impact from the blower, but the bottom end certainly will.

Exactly PT, I'm glad we agree....

... You're augmenting the factory 'build' that fails to handle the mods your planning to run. Or you wouldnt be O ringing and pinnin.. Just strapping on a blower to a motor is a gamble at best. If I were to do it, I'd do it your way.

Speaking of which, is that something one can plan as an upgrade? I mean for my 04 d2, if when we decide to do the top end, as I'm sure I'll have to, maybe it makes sense to dive into this as a planned mod. What does your setup run $$$ and whose blower are you using? How do the pulleys work? will it work on my rig?

Remember to put oil in it.

definitely. I think the failure rate on the rimmers was pretty high.

Here's some pictures and any input where the rising rate regulator lines connected?

you gave me a woody this mornin...

Salvador:
The fuel pressure regulator should probably be attached to a straight source of unported engine vacuum. If you compare it to the stock setup, the fuel pressure regulator is connected to full vacuum that is not affected by throttle plate position.

Mookie:
I've done some looking around. There are some aftermarket setups that might be able to be adapted to our use, but the fabrication, machining and engine management system developmen might be cost prohibitive. There are many folks selling blower setups for Ford 5.0 litre engines that would likely be sized well if slightly underdriven. I'm afraid the lack of access to the fuel map of the Motronics EMS would require the use of an aftermarket EMS like Megasquirt of pro-jection. Of those, Mega-squirt would be the only one coming close to being affordable.

x2 on what PT said. I think just straight engine vacuum.
