If you do not mind, what size is the turbine wheel & the A/R of the turbine housing of your turbo?
Do you have a topic here with your build info on your Mustang or is it on a different forum?
Thank you.
Its a Precision T4 88. Its the smallest 88 they make. The housing a .96 ar and 4 inch outlet. Most of the 88's are T6.. like the X275 cars use. Those are way larger.
Dont know if I have a build info on it here. Basic run down on engine its a A4(4 bolt main) block, .040 over, JE off the shelf pistons, JE rings, Eagle crank and H beam rods, Holley Heads cleaned up, Victor Intake with Wilson elbow. Cam is a hydraulic roller from Cam Motion. Specs??? been 4 years.. its their largest hyd roller before going to solid roller. Double roller chain. Has Ford roller rockers, FMS(Ford Motorsport) graphite head gaskets, Block was o-ringed previously thats why the graphites. And they've been holding up. Maybe do some coppers on a future build. Balancer is a Proform.. Meziere electric water pump.
Transmission is a powerglide and has the 1.80 straight cut gears, JW bellhousing, and added clutch packs. Converter is a TCI ProXtreme. Rear end stock 8.8 with Moser axles and Eaton posi. 31 spline. Engine management is an XFI I took of my TTA. Runs TFI distributor(stock) and bank-bank.
My only fights have been boost control.. and that is getting handled. But aside from that.. no issues. Just plaqued by oil pan plug leaks(yes its the little things
) .
One of the big helps is having 1/2 inch head bolts vs 7/16 stock. Like on a Buick. That seems to have helped keep the heads on. Tq on those was like 110 ft lbs.
Turbo kit hot side was from Pony Down. Was originally designed for a way smaller 76 turbo. The cold side was redone recently locally. Exhuast.. 4 inch DP reduced to 3.5 DP to a bullet muffler by the rear end.
