We are running a phatshaft turbo, 90hp injectors, and 16.5 degrees of timing on our fummins conversion with a 4" exhaust and a 3k gsk. Truck is used for heavy towing quite a bit in the range of 32,000-40,000 lbs gross. We plan to install head studs soon. What would b a good fuel plate for this application and also how high can we go with the boost. Its set at about 22psi now. I was thinking more in the neighborhood of 40psi. Also looking for good fuel mileage when not towing. Any suggestions would be greatly appreciated.

 

holyballs 40k lbs gross?! PICS!!

 

I run a 100 plate and luv it it's not jumpy on take off like a o or no plate and it don't smoke a lot when your trying to be nice but u still have good power and all the smoke u want on demand

 

Thanks for the input. I was thinking about using that plate or a #5, hadn't decided yet.

 

try stock at full advanced and play with your afc and star wheel a little bit before buying one, but a 100 would be good other wise, also you really don't need head studs until mid to high 40's just retorque your stocks

your right thats a lot, but i know few people including myself who have red lighted for 40k+, fyi note a cheap ticket

 

haha pics would be swell

 

Yeah, its quite alot. Its a work truck that we use to pull heavy equiptment and materials. We've bumped 48,000 a few times. Of course Not legally. Sorry no pics though.

Yeah Thats what we were doing for awhile with the stock plate and tuned afc, until now, its time for a tune-up. I decided to try and regrind stock plate myself to a tst#10. All I can say is awesome. Now if i can get the phatshaft to spool to 40 psi we'll be set. Thanks for the info on the headstuds, I was wondering about that.
