Here is my old (only) dyno...



My car was owned by a 55 yr old female french teacher. I got it in April with 62k miles on it.

Anyway... ALL I had done before this dyno was drop everything BEHIND the cat, and replace it with a single bullet muffler.

The 240rwhp is the accurate number. The 259rwhp was with the throttle body totally open.

Well turns out the stock paper filter was still in... and so dirty it was not even KINDA white. The power was unsteady and dropped after 4500ish. Since the dyno I replaced that filter with a K&N stock replacement. I removed the cat and replaced it with straight pipe. That 4500rpm range got WORSE eventually, the car would jolt and lose ALOT of power. I changed plugs and wires and totally fixed it as far as how it FEELS. I did a pert shampoo mod and the TB bypass.

So basicly SINCE this dyno pic,
-Replaced a HORRIBLE air filter
-Plugged the air *****
-Bypassed TB coolant
-!Cat
-Fixed all noticeable power issues w/ new plugs and wires

Any guesses as to where I should be dynoing NOW? And anything else I should do before I try to dyno it again?

hmm, maybe 10-15 more hp maybe a little more.
