Default Dyno guess anyone?

2004 GTO M6. Put down 290.6rwhp & 304.4rwtq.
Added torquer v.2 cam, non-ported Z06 243's w/PAC. 650 beehives and of course its gonna be tuned all tomorrow. I'm just getting kinda anxious and wondering what it might do. I've decided I'm going to let them set the limiter at 6800.

If the cam adds 40rwhp & the heads 20rwhp and then a tune I'm hoping for maybe numbers around 360-370hp/350-360tq.

What do you guys think?

those seem like really low baseline numbers... was that on a Mustang dyno? I think 60-70rwhp sounds about right for that H/C combo

Not a mustang dyno but they said the numbers were corrected to make it read more accurately. He said he could make it read more like a dynojet But it'd inflate the numbers. Just got a phone call telling me it'd be Wednesday instead of tomorrow because of the weather.
But yes on my part I felt the numbers were a little low originally.

Id say with a good tune you should make 400 rwhp easily. My numbers in sig were at only 6k rpms. (125k stock bottom end) on a mustangdyno. And it was still pulling hard when we shut it down.

Not with a baseline of 290hp he wont. Fortunately, dyno is just a number, what it runs at the track is really the only important number.

Yeah, plus I have stock manifolds and exhaust. No bolt ons except K&N cai. I don't expect it to be a demon, just more of a sleeper decent gas mileage w/ high 3xx rwhp. I also need some wider wheels/tires. My car ran 8.99 @84mph in 1/8th. Spun bad leaving at 3.5k rpms. That was on some 225's. I've got 245's now which is as wide as my wheel will hold. I'm not going dr's cause this is my daily but I'd be happy with mid-low 8's.

Honestly I don't think you'll have any issues getting that kind of HP if you have a few more bolt ons. When I add headers and a few other things I believe ill be up & over the 400rwhp mark. Until then ill be happy with what I got.
