last one i had that went ok was

289/315

that was before the exhaust and pullies. mods in sig. basically just a full bolt-on A4. no track times yet

the actual last one i had was 275/310 or something, with everything in the sig except the trans. and stall. dont really understand it but i wasnt there when they dyno'd it so i dont know if something went wrong. I had to run and get some stuff and they dyno'd w/o me

I would say that at least 9 out of 10 people don't degree the cam. Dot to dot gets you within 2 degrees usually.

It's been a while since I've seen a dyno test on this, but I'd be willing to bet it's less than 5 hp and probably not even repeatable on the dyno.

I've seen them off by as much as 5*,
that could mean up to a 15-20hp difference
depending on how far (and which way) it is off.

If you are spending that kind of money on a cam and time to install it,
spend an extra $30 and a few min on a degree kit.

270rwhp/292rwtq

Dyno seems to be a little conservative but maybe not you tell me. My signature shows what the car did with at these #'ers.
