Strange dyno results, need opinions

Put the Formula on the dyno today and got some very odd results...202 hp and 426 ft/lbs. The dyno operator didnt seem to think anything was wrong, and he said a LS1 TA just dynoed 220 odd hp the other day. I thought that the hp and torque curves were supposed to cross at like 5250 rpm, but they obviously come nowwhere close to each other. So my question is, what kind of hp and torque should the car be making? Its a 95 A4 with ported heads that flow 240/190, 224/230 .503/.510 112 lsa cam, and a CAI. Completely stock exhaust for the time being. Thanks

You should be making between 280-320. That dyno is messed up. I'd ask for my money back.

That is odd, What type of dyno you used? There are two type mustang dyno which shows a low rwhp compare to a dynojet which everyone seem to use much more. A tuned cam/head LT1 should be well over 310rwhp.

It was actually one of these http://www.mainlineauto.com.au/products/2wddyno/

310 rwhp was actually right about what I guessed of I should have. I dont know about the torque though. Is the torque reading as much too high as the hp reading is low?

that dyno guy is a moron. your car should be around 330-350 or so. and even a stock ls1 should be around 300. what gear did he dyno the car in? auto or manual? that dyno is screwed.
