Swapped Cascade 2 into 1 for Graydon

[Bancheez]

Well, i have been running a cascade 2-1 intake with a 35 pwk all summer w/a 195 main. I swapped the cascade out for a graydon to see if there was a noticeable difference. WOW, What a difference! first thing i noticed was a HUGE increase in top-end pull. I figured i would take it out and do some plug chops to see if jetting was any different over the other intake. First plug chop (195) had NO collor. Jumped to a 205 and did another plug chop, still no collor. Jumped to a 215 and finally got about a 1mm smoke ring at base of porcelain. installed a 220 main and ran it (no more plug chops though, i had enough for the day). It definately makes a SH*T tone more power mid-top than the cascade, but i can't figure out why the jetting would be so different. Does it just flow that much better than the cascade? The engine is a ported 4mill w/VF3s and cascade stuffers. I ran a graydon intake a few years back on my stock port motor, and that too always seemed to run much larger mains than what everyone was running in their Cascade or trinity intakes. any input on this subject would be great. thanx guys.

I would have to say from my experience that a straight shot is always the best route for an intake runner. The cascade intake isn't very good in that aspect. But the graydon is very much better. The longer tubes will give a better midrange for the very small sacrife of an unnoticable amount of throttle response. see my jetting thread for pics of the intake I'm building to last me through to snowmobile season.
