Well explain these dyno #'s with the TR 224/.563/112LS runs Well finally got the car to the dyno today for some tuning with the new cam. Well the car sucked all around as I almost predicted. NA best pull was 366RWHP and 362RWTQ SAE#'s and then the part that really pissed me off!! I getter ready for the Nitrous pull with the 100jets still in. Fuel pressure doesn't drop below 55psi at all with the nitrous on, bottle pressure 1050Approx as before, TR6 plugs all good, etc etc. All the same as the last time but 30degress warmer this time. I put 100octane in to keep things on the up and up just incase. Well here goes the DAMN #'s are 471RWHP and 515RWTQ. Yep take a look at the sig I lost 35ftlbs of torque to the rear wheels with my new cam and same HP to the rear wheels no gain. The worst part is compared to the old dyno pull of 550RWTQ there is ALOT of area under the curve compared to my new one. I'd say in some parts later in the RPMs its almost 50RWTQ off atleast difference. Soooo should I shoot myself now or later??? This almost explains the other post of times it ran.

Re: Well explain these dyno #'s with the TR 224/.563/112LS runs cantdrv45 you suck and I never want you to talk to me again!!!!! 
You can tell me it sucks I know it. hell I went to the extent to make sure I had the same tires on, timing was good, changed to a lower pill once 3200 and a 3400RPM pill no changes. She aint what she used to be!

Re: Well explain these dyno #'s with the TR 224/.563/112LS runs Hmmmm not many comments on this huh? Doesn't anyone have the reason why the car lost torque with the cam?

Re: Well explain these dyno #'s with the TR 224/.563/112LS runs Since the ambient temps were ALOT higher the PCM may have pulled a little timing. Those numbers are good however! You still made the power which is all that matters...

Re: Well explain these dyno #'s with the TR 224/.563/112LS runs Thanks for the replies....
No pics of the dyno sheets yet. The air fuel did go richer with the cam down low between 3800 and 4200RPM (dips down to about 10:1) then on the cam run its a bit richer across the board at about 11:1. The before cam air fuel went down to 11:1 at lowest and stayed for a bit then cam up to 12:1 then back down to about 11.5:1 at the end.
Old cam was a stocker.
Definitely gonna have to dyno in cooler weather NA and N20. Just money right?
