I will sure do that...goin by comps numbers with stock heads intake and exhaust they give 50 plus hp
Don't believe all the hype you read. With UDP's, K & N Typhoon CAI, aluminum drive-shaft and dyno tune I had 289 rwhp. I installed the stage II Thumpr cams last fall, motion delete plates and larger Steeda CAI and gained less than 10 HP. This spring I had 3.73's installed along with Kooks headers W/catted H-pipe. Car feels tons quicker now. I won't have dyno #'s till around June. The cams really need a free flowing exhaust to work well.
Some of the info you don't read usually is that if you want stock drive-ability leave your stock camshaft in. Don't install a rough idle cam and then be surprised it does not drive like stock. With a rough idle cam you will need to downshift at or before 1500 rpm. If you lug below that coasting or steady throttle you start getting into the cam lope which translates to the car bucks. You will also need either 3.73 or 4.10 gears to give you better slow around town drive-ability.
I don't think I would go the Mother Thumpr route as you could expect worse drive-ability than the stage II thumpr's. If I lived in a high traffic area where I did lots of slow clutch in/out driving I think I would leave the stock cams in.
OK, now having said all that I really love my Thumpr cams. After my gear & header install I have almost perfect drive-ability with Brenspeed's tune. I am glad I did it and would do it again.
The sound of the Stage II Thumpr's is just fine. http://cobrapages.com/camheadres.MPG
If you want max HP from a NSR cam there are better choices.

I am goin to have truly a free flowing exhaust no cats and no mufflers..im still lookin at headers right at the moment...i do plan on putting 4.10 gears in the car but also getting the t-6060 transmission kit..which will come with aluminum 1 piece driveshaft short throw shifter bell housing...the car is mostly goin to be a show car but will see some track time...heads and intake will also be getting changed along with a 302 stroker...so perfomance wise i will have a stronger car buti know it would be better with different components but for what im wanting it will work out good
