Had my car dynoed today. Basically just has long tubes and or-y and ported tb. Made 305whp and 317 ft lbs on the full exhaust. Made 315/321 on open y pipe. Now i'm not too depressed with these numbers, especially since this particular dyno is known to be stingie with numbers. how does this sound to everyone else?

I made 310 on a dyno jet with full exhaust and a intake... It's automatic

Hmm sounds about right then. Mine was on a mustang dyno that tends to read 10 hp or so less than other local dynos. I am also still on the stock ls1 intake and lid assembly even

Every dyno is different. Dyno jets calculate HP differently from mustang dynos and usually dyno a lot higher. I know someone who puts down 400 on a dyno jet then puts down 350 on a mustang dyno.

I made low dyno numbers when my Z28 was stock but yet ran constant low 13's. 13.2 was the best. I didn't get it at all.

Looks about average for an ls1 intake car.

Just dynoed mine today. It's a 02 firehawk a4 all stock except for the electric cutout on the I-pipe. On a mustang dyno it made 311hp and 305 ft lb with cutout open.
