Those are ugly *** numbers. My motorcycle has almost that much HP. and it only weighs 470LBs.

I bet my N/A with 201k miles has that much HP ... there is somthing wrong with that dyno, or more than likely somthing really wrong with you car... need alot more details though. Are you even hitting boost?

Yeah, those are some sorry numbers for a TII. The N/A's get that stock. Its probably the cats if everything is stock.

It can also be a stuck thermowax that's not letting the secondary throttle plates open up. You got some wrenchin' to do.

Why not even remove the Secondary Throttle Plates all together. You'll gain .5 hp to the rear.

Why didn't you get the chart on print out or on a disk? I'm sure the dyno operator saved the graph, go ask him for it on disk and post it.

Even on a Mustang (load bearing) Dyno, those numbers are low...

Can you post the dyno sheet itself?
Sure, the numbers are low, but the graph itself will easily tell us if something is definitely wrong.

True you do have some wrenching to do, but at least you know where you stand now. By the way those numbers are pretty close to spot on of a '86 N/A stock (the tq is a little high)...so you definately have some work ahead, but it'll be fun!

Just removing the plates won't get you much... just cuts out a point of failure. But, removing the plates and porting it (or having BDC do it bdc196@attbi.com) will show some VERY nice gains....
