94supercam Posted January 8, 2008 Report Share Posted January 8, 2008 I have a 01 banshee that came with a 68mm cub cylinder. I blew it up cause the water pump gear stripped where the roll pin holds the gear. Anyhow I decided to go with stock cylinders that have a 65mm .40 over bore. The cool head that came with it is a trinity with 19cc domes. That says 69mm, then 19cc and 9 deg under that. I also have a adjustable timing plate. What compression will I have with the stock cylinders an 19cc domes. also what should I set the timing at? Will i have to run race gas with the 19cc domes? Thanks Later Ryan H.

Bansh-eman Posted January 8, 2008 Report Share Posted January 8, 2008 (edited) your comp has many factors. its hard to give u any numbers not knowing if they are ported and or how much, plus temps altitude and other factors will make a differance ... aa far as running race gas or not it would all come down to getting it together and doing a compression test. we could guss all day long but the only way to know for sure is to check it. edit: the nossmachines site has the chart your talking about go to the bottom Link Edited January 8, 2008 by Bansh-eman Quote Link to comment Share on other sites More sharing options...

94supercam Posted January 8, 2008 Author Report Share Posted January 8, 2008 Already sold em sorry bud. Thanks for the link!!! At what PSI do you need to run race gas?? Also theses are stock cylinders with no port work. What do you guys with stock ports set your timing plate at? I think mines set up at +5 degrees? Thanks for the help guys Quote Link to comment Share on other sites More sharing options...
sheerider1026 Posted January 8, 2008 Report Share Posted January 8, 2008 heres my setup, trail/play port, stock cylinders, noss head 19cc domes, +5 timing, 2 into 1 carb, t5 pipes, K&N.. i run 93 pump gas and its a fast mofo, i would be afraid to stretch my tune anymore on it, but it is safe right where its at.. so yes i have ran 19cc domes on pump gas, but it also depends on altitude, i am about 500 ft asv.

Bansh-eman Posted January 8, 2008 Report Share Posted January 8, 2008 at 150 psi, i start mixing race with premium. some guy will go higher but i feel more comfortable running the race gas. its cheap insurance and peace of mind knowing my motor isnt going to break down.

jbooker82 Posted January 8, 2008 Report Share Posted January 8, 2008 I ran 155 with 4 deg of timing on 91. If ur running BB domes ur compression will be a little lower than with standard domes. Quote Link to comment Share on other sites More sharing options...
