You had the XR rebuilt with that HP and tq, and have 30+ hours on it. That is great. I may need talk to Mr Gadgets. about updating mine

GPM

I *HIGHLY* reccommond Mr Gadgets.
Now back to your thread, I think you will be very happy with your Procharger.

I am still in awe of a 7500rpm 598. You wouldnt happen to have a video with good sound of that laying around would you? It would have to sound wicked. mine sounds pretty sweet at 6200rpm, so I can only imagine.

Back to the thread. Don, have you discussed the cam specs with anyone yet? I would be interested to know what kind of lift and duration you had in mind. What about compression ratio, are you planning on keeping it low, like 8:1? Or even lower due to the boost you will be running?

DonRoc

I am having Mike Jones of Jones Cam Design build me a cam (they even balance the cams...)
I will get some spec's and post them. The compression will be 8 to 1, I ordered a pulley to give me 10 psi boost (should be close). I am told I can get away with 12 psi and pump gas on a long run and up to 15 on a short run. Of course that depends a lot on the cam and tuning. I think 10 psi will be enough for now. When I get the SCX I may boost it up some and run race fuel for the radar runs.

GPM

Not much for videos

DonRoc

Sounds good.

GPM

Thanks,

Don, have you spent much time tuning the Accel DFI ?

Mr Gadgets

Don,
Red Zone EZ wheels, make sure they are the Jim Oddie wheels.. otherwise.....

DonRoc

Yes nothing but the new Red zones. isky is saying they are getting 40% more time between failures. over there needle rollers. That should give me 125 hours between changes. I am really conservative I would rather be overly safe and spend a few more $$ than have a mess. once I pull them at 100-125 hours and take a look and adjust my service intervals from there.

Looking forward to some parts comming in and posting some pictures.. Maybe by Christtmas.
