Engine/Transmission (1994 - 1998) No Torque Plate???

well, i picked up the pump today and installed it. the idle is too low at 625rpms, but it sounds awesome (like a slower HeberRam's idle). the motor seems to be a lot louder (or just that i haven't driven it in 4 weeks).



the plate is different than a "regular" plate. i dunno if i'll get around to putting my ground plate in there as i'd have to break the tamper-proof screw in the rear to adjust the arm up. the rack travel is less as compared to my 180 pump.



as for performance, the thing is as laggy as a 24v:eek: once above 2100rpms, the fuel finally gets pouring. i *definately* need to adjust the AFC. my boost went down from around 34 to around 29. egts are at 1050 unless i let it wind out. the fueling is down on the top end, but it feels almost as strong as my stock pump.



governor springs: they're heavier weights, but heavier springs too. it doesn't run like a stock 12v, but it's not 100% as good as the 3000rpm gsk; maybe 85%.



Overall i'm very happy to simply have my truck running again. it's going to take some playing with, but it'll work. Big thanks to all who have helped me here!!!

i pushed the stock plate full forward and adjusted the afc. the throttle feels/acts very weird. the first 3/4 throttle goes up to 2100rpms and hits a breakover point or something. from that, my shifts are a little more harsh. the last 1/4 throttle fuels the top end quick and hard. my transmission really hates life at full throttle (no major slippage though... yet). i did keep in front of a 6. 0 chevy that wanted to pass this morning. Oo.

Since this is a marine pump - it will act a little different.



I imagine that this pump wasn't really designed to accelerate/decelerate like an automotive application would require. Most marine engines get up to a certain RPM in a pretty short time and stay there all day long.....



I could be wrong - I'm just doing a bit of a brain dump... .



OR - it could just require a bit more tuning..... which wouldn't be a bad thing - you'd do some research/learning while you're doing it.

yeah, it does fuel quick. the thing i really notice is how fast it start: immediately. my old pump took about 3 turns of the motor until it caught. the exhaust also smells different (NOx has increased).



i've got a little bit of smoke coming out to get it up to speed, and it does smoke at WOT at 34,34. 5 pounds of boost.
