Super Jet Ada 33cc domes on a 710cc...93 octane

[jloria]

Just wondering if I could run 33cc domes on a 1996 RN SJ 62t/61x with 93 octane

LPW built my previous ski and I am pretty sure he recommended 33cc domes but it was a 735cc.

dual 38's and planning on adding a msd enhancer

or should I stick with 35's?? no issues getting 93 octane here

thanks!

Not recommended according to ADA's Site. I could be wrong.

Yeah...I was on their site earlier but I figured I would ask. I thought i read a few posts where guys were running 33cc's on 93 but I could be wrong too.

Im doing 33's on my 83mm LPW, but the ports are raised a bit.

a friend of mine runs 33cc on 93 octane. no problems. msd enhancer, b-pipe, freestyle portjob,

It can be done, you just need to limit your WOT runs.

I run mine with 33cc domes on race gas, better safe than sorry.

I am running my fixed steer with a 61X/61X with ada head w/33cc domes.

running 93 octane pump gas and do WFO throttle all over the place. If it is jetted properly you can do it.

This is on a stock port motor out of a VXR pro. I didn't do anything other than plop a B pipe and head on the shortblock. Didn't touch the internals. If you have any porting done it should lower the compression a bit anyway.

Thanks for the input.

i'm running 31cc domes on my Rn and my wb1. both are 62t/61 x motors. One has OEM cylinders and the other has sport spec port job. Both skis are running msd enhancers and b - pipes. Compression on both skis is just shy of 200 and I run 93 in both of them. No trouble yet but I do watch my WOT runs.
