and everyone elses!

 

Well, next part came in. 255lph walbro pump, again off ebay, $99.

part 3 is here also. Inovative LM-1 and LM-3 aux-box combo. Ebay $469. saved 120 over everyone elses price. Just had the bung welded in late yesterday. gotta keep up with those a/f #s. pix later

 

test fitting the 4" intercooler. Had to relocate the transmission auxiliary cooler to just under the radiator support. next up...plumbing!

 

how much boost are you planning on running, and i assume there is a plan for a tune?

I will be closely following this thread because we are about to boost my buddies 2.8l VR6.

 

ill be watching this too as im saving up money for a twin turbo project

 

Well, with the airflow requirements of the engine over its operating range, the turbo will be able to supply 6to15 psig of boost, i will be starting near the low range as the motor has stock pistons and rods, but an upgrade later will allow use of higher boost levels. the tune will be done by the troyer gang.

 

Just remember that when you do two turbos, there is twice the likelihood that a failure can occur. Are you going for looks or do you have a reason for going twin?

 

yeah im going for 1000 hp... dont worry.. ive done my homework

 

Can't wait to see numbers when it is complete!

 

HI!... 1000H.P is easily done with a single turbo. A T-76 or larger will do it no problem.

 

why would you want just one when you could go twin.

 

you are correct, neal. a t70 will go up to around 800-850 at best depending on the buildand the rest of the components

 

One big single turbo or two smaller turbos can conceivably produce the same numbers on the dyno. However, the twin setup will start producing horsepower at a lower RPM. And, in a truck that is where you want alot of power at. FYI, I own a Nissan 300zx with two GT28's and it they start spooling at 2000 RPM, so that I have plenty of power off the line.

 

How much lower do you think it could possibly be? My friend just swapped over to a Precision 76mm snail and it spools so fast from a dead launch the 10.5 slicks are fighting for grip the first half of the track. Really no reason for a twin turbo setup either than just to say you have it. Performance gains will be nill...and possibly less as it's just added weight.

 

HI!... Most of the guys around here that have built or bought a vehicle from the factory with twin turbos, switch over to one larger turbo. I have a 3000 stall converter, so I couldn't care less at the H.P I make at 2000 rpm. A T-76 on my engine with my custom turbo grinds will make power from 2800 to 6800RPM. Lot's of power band there to use. Plus I have 4.10 gears so turbo lag out of the hole will be non existant.
