98 Z Bolt-on Results and a Question Dynoed my 98 Z at Dynolab yesterday and it put down 322 rwhp and 339 twtq. This is through an automatic transmission and the car has nearly 58000 miles on it. The car has the following mods: FTRA, MTI lid, PACE MAF with screen, MMS TB, HPP3, MAFT, Hooker Headers with RT 703000 cats and a Dynomax Racewelded muffler. I probably could have picked up some more power on dyno by unsealing the FTRA/Lid and putting in some fresh plugs. The current TR55s have over 13000 miles on them.
On another note, has anybody watched the oil pressure while running on the dyno? At WOT the pressure would be fine, but when returned to idle it would read between the first mark and 40. If the car was shut off and then restarted the gauge would read the normal 40. It did this repeatedly even after the oil was topped off over the full mark. Any ideas?
Thanks

Re: 98 Z Bolt-on Results and a Question Sounds about exactly right. I wouldn't expect any gains from the FTRA on the dyno since you're not actually moving. I have pretty much the same mods as you except with different brand stuff (FLPs w/cats, directflo lid, etc) and I put down 323rwhp. You just have the MAF and the TB over me.
