Cam Timing- MCX Phazer

[rfabro]

I have an MCX kit for a Phazer I'm about to install, and they say to slot the cam sprockets to retard both cams to their original positions. I was thinking of leaving the exhaust cam advanced or retarding it less, for better bottom-end response. What do you guys think?

Could anyone who's done some testing with the stock cams like this, elaborate a little on the effects, in other boosted engines as well as the Phazer?

And yes, I did read Hammer's dissertation on cam timing, and it was awesome. I had to print it out and archive it in the sled section of my file drawer. I'm just looking for real world observations of fiddling with the stock cams.

Any other hot tips?

Thanks guys

I did the cam timing myself, Thinking of Removing the shim and unadvancing the timing. I'll lower the boost a few lbs. Comression should help it spool faster. I haven't rode one without the shim and timing, but sounds like the best for lag. ALOT easier install as well

I built a mcx phazer last year , did the head shim, and cam timing.
I also tried it with the stock cam timing ,did not notice any difference.
That said I would leave out the head shim , leave cam timing stock , start at 8-10 lbs of boost , av gas mix and tune from there !
The guys in Revelstoke last year ran without head shim , stock cam timing , c112 race gas at 14 lbs boost and had a blast !!!

Get in touch with Randy Swenson for the details.

I was really wanting to run pump gas.

Is the lag that bad?

Some guys swear there is almost no lag. What do you think that's all about?

The guys who say there "Is almost no Lag" have been
It's still a Completely different sled after boost, but the lag is VERY noticable with the shim.
