c 15 boost - 03 mbn flashed to 7cz 600/2050

Hi guys. Got a 03 mbn flashed to 7cz 600/2050 bs. new head gasket and deck plate. new exhaust manifold and none wastgated turbo. pulling 40 to 45 pounds boost. what will the motor/head gasket take? thanks.

 

Boost doesn't blow head gaskets

 

i think i see some room for one more.

 

This is PDI's Limo truck, which has actually been coverted back to a standard 379 with a 63" flatop sleeper

The engine is a C-16 600 hp, the only internal engine modificatios are injectors and camshaft. In this configuration it put 1665 hp to the tires

 

Mr. Haney:
Is the cam and injectors a guarded secret?
Thanks for the pics. Most impressive to a simple guy,like me...

 

The cam is a PDI Stage 3 installed one tooth advanced with the crank timing sensor disabled, the injectors are PDI Stage 3s that have been modified by extrude honing the nozzles a considerable amount for more flow.

 

I think 4 would have been easier to plumb, but may have been very sluggish. I haven't ridden in the truck, but everyone says this is sluggish to light up also. They also say once it spools, you better have some open space in front of you.

 

So they add two extra chargers and only gain 260hp, I know at that level its alot, but seems a traditional compound set up may have seen better results.

On another note, this tripple set up is different in the way they have been staging them on the pickups, and may be the reason for the lag, usually you see the two smaller turbos feeding the larger one.

 

The dyno lost the battle at 1665, it never pulled the RPM down. The power came on so fast the dyno pull was only 10-15 seconds long before the tires broke loose.


I'm going to keep quiet about the turbo set up......I don't know if PDI wants everybody to know how and what parts were used to build it or not. I don't think they'll have any customers for it and it was strictly built for hp and not drivability

 

Ok as I look at this I need just a min.......alone........to think
