Dyno'd the Jeep today

[zfinger]

So I am a member of a Nissan 240sx car club. And today we had a big dyno meet at F1 Dyno in Portland Maine. But my Nissan has no engine in it at the moment, so at the end of the day I ran my Jeep on the dyno. Once I can get on my moms computer and scan the graph I'll post it up.

144.7hp and 198.2 ft-lb. Thats not too shabby with 190K and 33's.

What are the stats on your Jeep? Any engine mods?

 

[OT]

What about gearing and trans?

 

[zfinger]

Automatic, I dont know what gears either, 4.0
Flowmaster 50 Series and Magnaflow high flow cat
K&N drop in filter too
and the 33's

 

[Dr. Dyno]

Those are respectable numbers for an auto XJ 4.0 with 33's. Which gear did you use for the run?

Honestly I'm not sure, I wanna say second.

 

[YMMV]

THey should have used 3rd gear. You want the gear with the closest ratio of 1:1

4.0+auto XJ would be 3.55s unless you have towing package/fuel economy package

When was there an econ package? 3.02s came with manual trannies, 3.55s came with auto trannies, anything else is aftermarket.....towing package basically just added a Class 3 hitch & standalone tranny fluid cooler (as opposed to the integrated cooler in the radiator)....

'87's & 88's had a chance at the d44

Manuals came with 3.07's not 3.02's. 4-bangers came with 4:10's, and I have personally seen an 88 with a factory 5 speed manual and 3.73's...
