Re: The "4.9 liter turbocharger, stage 1" thread.

You know what I've just realized? We're getting nowhere fast with this project! There has been about 140 posts pertaining to pistons and camshaft changes that I will not use at all for stage 1

Let's get back to topic here and start to figure things out. I mean Christ, it's just another engine with the same characteristics that almost every other V8 has in terms of moving parts...So I'm not getting all fancy. It's just a tune before the real deal if you please...

Ok, for stage 1:

a.) No intercooling whatsoever. Tom has stated time and again that for 6 simple psi that it won't be needed.

b.) Fuel. I'm just going to order the Megasquirt self-programmable system and get with it. I have most of what I need and will run with an auxiliary TBI system to add more fuel. I'll add the extra fuel pump and lines too.

c.) Timing. So I'll keep factory settings of 10 for idle. The MSD boost timing controll can take care of the rest.

d.) Turbocharger. I would like to have the compressor map done, but I really feel that the turbo I have will suffice for now.

e.) Tubing and pipes. I'm installing the turbo via the crossover pipe from a Deville. There will be Deville front and rear exhaust manifolds feeding the crossover pipe, which will in turn feed the turbocharger.

f.) Boost level controls and a blow-off valve. Done. The turbo I have has a dual-port wastegate system and the boost control should work out fine.

All that is really needed is for me to order the Megasquirt and build it. Welding pipes and other things together is easy. Or at least I hope so.

Okay people, let's get with it here. If I'm going to blow this thing up, let's do it in style!!!
