Default 3.3 Ported crank and sleve pics

I have had this engine for 3 years on the shelf. The sleve porting was done after break in a few years ago. The crank was ported today. All porting was done by ME. The sleve porting gave some top end power with an rd logics dual exaust, now there is a resonator high rpm pipe on the jato. I have not run it yet with the ported crank- need to go to the lhs for some fresh fuel.

What do you think ??

Nice job. I tried it once and failed but I will give it another shot one day.

I ran 1/2 tank through it this afternoon and it seems to have quite a bit more punch. I can spin the rear tires at will on pavement. I need some more fuel and to tune it a little better. I will see about putting up a video soon.

Man... don't use a Dremel. Get a nice set of needle files, it takes a bit longer, but the end product is A LOT better.

LOL too late bro it is allready done and running. This is the reason the jato has been dusted off and fired up again, a OS NoS system that was cheap on bay I have a long stretch of road outside of town that is going to be the testing grounds.

OS never made one of those. That is made by RB Innovations, and is a pretty quick way to blow out the top of your conrod. Nitrous in nitro RC car engines leads to preignition, which is bad.
