Modified 6.5 Build

[6.2 turbo]

Have to take the turbo and intake off,so I can install a charge psi gauge and crank it up slightly.

 

[6.2 turbo]

Not enough timing at idle,so would like to see 75 psi mininum.

 

[6.2 turbo]

Well I got 40 psi at idle and 80 psi at higher rpms. This is where a 30 psi lift pump would be perfect, instead its more like 5 psi.

 

[6.2 turbo]

Swapped the charge pump regulator with a previously modded one. I also upgraded the spring. Now It has 85 psi at idle ,and max psi of 125. This advanced the timing enough to enamble the ip to be at the line.

Yea, the nozzle was leaking compression into the fuel. I heard it can happen, just never seen it.

30K on leaking compression into fuel line injectors with Red China nozzles looks like this:

This advanced the timing enough to enamble the ip to be at the line.

What do you mean, "the ip to be at the line"?

 

[6.2 turbo]

I had the ip advanced 1/4 inch past the line,now with more charge psi ,the internal advance moves farther. This eliminates the need to have the ip past the line.

Gotcha. Thanks for clarifying.

Well we drove it a few miles. Makes 20 psi boost ,prob will do a bit more, but kept blowing off intercooler boots. Has a bit to much timing at part throttle , and hazes a tiny bit at idle. It has a nice exhaust sound also.

[MrMarty51]

That sounds very nice.

 

[6.2 turbo]

Well it makes 28 to 30 psi boost. The timing needs some fiddling with . The lowered compression,combined with a big intercooler makes the idle timing a bit complicated. I'm going to have to bump up the idle speed . Also the clutch slips , ceramic,but stock pressure plate.

 

[MrMarty51]

I was hoping to see pics of the tube/hose routing for the intercooler and the intercooler itself. is that one of the units mounted behind the front bumper ?

 

[6.2 turbo]

Yes it is behind the bumper. The bumper is from a semi,so we had lots of room.

[MrMarty51]

OOOOH YEAHHHhhhh, I like that. LOL

 

[6.2 turbo]

Got the timing pretty good now. It's either the 3500 psi pop injectors,or the .040 shaved pistons plus .010 over gaskets,thats delaying idle ignition timing. The pump internal advance is all the way maxed at idle,and the ip is advanced alittle past the line. So it has a ton of injection advance at idle,to get clear exhaust,only after the motor is warm.

At a local car show today .

Do you have a Ferret or something else to measure your timing or do you just do it by sound?

Sharp looking rig.
