RPM Airgap vs. non-Airgap?

dave
is that a true calculated 10.1 CR? If it is and with the cam you have 244 it will bleed off some compression at lower rpms, so if the advance curve all in is delayed to 2800-3000rpm you should be okay - on the verg though.
The Air-gap is supposed to be worth 5-7hp over the Performer - but in cooler weather like we have in most of the year (okay 10mths) they are a bit of a pain waiting for warmup - if it ever does.

With the RPM and 650demon, you will be amazed at the overall performance difference - going from boggy low speed to tire ripping is my speculation - that and a little first hand experience. Save yourself some work - just put it on and let it rip.

On another note:
Your outside garage setup pisses my off everytime I see that pic -LOL
I've had the forced air heater in my garage going for a month already and its only early Nov. - I can't wait until January!! :cussing:
