7.3L 38R Turbo Wheel Comparison

Bill, have you tuned any pickups with pulsars GTP38R turbo? If so how has it done?


Cleatus12r. Careful what you say about the 6.4, mine might hear you and deside to lay down and die!! Its got a little over 316k and still runs like a champ. About 100k of it has been done without a certain hindering system on.

I have not specifically. However, one thing you want to do with tuning any larger turbo is back the ICP and timing down a touch to help get the turbo spooled. Too much ICP and/or timing at low RPM tends to reduce the amount of heat energy in the exhaust and makes the turbo a little laggy off the line. Reduced timing helps low end torque and improves the spool of the turbo. Once RPMs come up, normal timing and ICP curves are fine.

Thanks Bill. So I guess no data show what it is capable of. I am sure must folks are scared of the knock off version. After all, it can be had for under 900.00.
