Its on ........ I'll let you guys know if it was worth it in the morning      

 

 

What are the complete specs on the turbo?

Went from a clipped 63/68/14 ED to a similar 66/74/14 ED turbo ....

Lag and spool up wasn't bad ... i still have too much fuel though. I'll either have to dial it back or go twins ....

60 psi out of the 66 .... pegging 1400

Cast 63 on left and billet 66 on right

So what are you doing with the 63?

Oh and I like the 66, very purdy!

Probably keep it as my secondary and stick a s478 under it .....

Not 100% sure yet ....

LOL... I was wondering the same thing about the spare turbo 

Have you done any 1/4 mile runs with that bad boy?

No ... The truck made over 1000 hp on twins and with timing advanced further ...

I'd guess it's closer to 600 hp right now on a single .... but thinking hard of putting twins on it ....

Biggest surprise for me was how good the 66 was at the bottom end .... Spooled much quicker than I thought ....

I guess because of the pump mods?  

 

I would think 7x.012's would fit that 66 perfect.

Yeah I definitely have enough fuel ... it's more just about the size of the turbine. Be being you have to push so much fuel into it from idle before your on top of it ....

That was surprising bit ....

I'm actually thinking of going bigger with a spool valve ....
