Dyno results from my first cam install.. TR220 I had posted Monday about my first cam swap and that I was going to wait for a few days before I dyno'd the car...
Ok, I couldn't wait until Friday, so I called down to Walker dyno tune and asked them if I could come today. I drove down there and we strapped my baby down and did 3 pulls. My MAFT tune that I had when I arrived turned out to be the best one. The results were.... 381.7rwhp and 371.2rwtq!! That is a peak gain of 39rwhp and 12rwtq! The numbers at other points in the run were much greater than that! I can't wait to go to the track Sunday now. This was thru a full exhaust with NO CUTOUT, NO short belt, NO underdrive pulley, 17x11 wheels, and NO ported Throttle body! Once again... I love my car. The cam is a TR220 112lsa.

Re: Dyno results from my first cam install.. TR220 Sorry,... I forgot to post my sig. I have Jet hot coated hooker long tubes, jet hot offroad y pipe, B&B triflow exhaust, Spec Stage III clutch, and a MTI lid. That's all.

Re: Dyno results from my first cam install.. TR220 Awesome #'s! <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> I see no reason for using a TR 224/112 on stock heads when you can use this 220/112 and make nearly as much power.
BTW, your running a little lean in the 4-5,000rpm area. I wonder why?

Re: Dyno results from my first cam install.. TR220 I went 2% richer on my MAFT after that run and got identical hp and tq numbers with a better a/f ratio. The car has 14,000 miles on it and I have never changed the fuel filter on it! On the third pull I got the a/f down too rich (12.5 to 1) and lost 5 rwhp. I auto tap'd the car and it isn't getting any knock retard at the lean setting... so I'm going to run it that way until I install my heads and have it ls1edit tuned.

Re: Dyno results from my first cam install.. TR220 Yep, the 220 is a great cam. My car made 380/372 with it on a 114LSA.
gomer, it looks like your car is running a little lean up top.

Re: Dyno results from my first cam install.. TR220 You happen to have your old dyno sheet prior to the cam? I'd like to compare the two. Nice gains. I'm really happy w/ my TR220.
