BEWARE: Tom Borrink & The Rocket Pipes

I wanna see what you have thack. You had a frame built right? I would think if you've made any headway with it and this cheetah motor lots of people would be interested. Post some pics!

I haven't got my lightweight, long travel, chromoly frame done yet Guns but I'm working on it a little at a time when time and money allow. I'm building the new frame out of 1" and 3/4" OD .095 41/30 Chromoly, tig welded, gusseted, heat treated, and powder coated high gloss red.

 

After the new frame is completely finished I'm ordering a Stellar +4 Heavy Duty Arched Ladder Swingarm, the YFZ-450R Walsh Racecraft LT A-Arms, and LT YFZR Fox Float-3 Front Shocks and a Dual Rate LT Fox Podium Rear Shock w/ Remote Resi. Then I can take a weekend and transplant everything over from the old chassis and over onto the new chassis. I'm still a ways off from having the frame finished but my motor is done.

 

I ended up building a Pro-Trail Ported Short Rod (115mm) 10 mil 535cc Power Valve Cheetah that's setup to run 100LL Av-Gas. I identified and addressed every part of the Banshee Engine that could be improved and updated. I don't have a bushing in my entire engine. The cases were machined and bearings and seals were used in place of them.

 

I'm running a micro-polished, cryogenic treated, pro-modded six speed with straight cut primary drive gears, billet 2nd gear, upgraded transmission bearings, full bearing c-clips, 8-plate clutch setup with DL stealth lock-up (Rekluse Tungsten Carbide Ball's) heat treated to clutch push rod, dual ceramic clutch push rod balls, and all the clutch and shift upgrades available for the Banshee.

 

I ended up coming up with a bunch of cool mods that would increase reliability and performance and extend engine life. For example, I wanted to increase my crankcase oil capacity. So I bought bigger Direct Drive Aluminum Clutch Cover and I started looking for a larger crankcase vent/check valve that would allow a little more pressure and heat to be released therefore increased the crankcase oil capacity.

I could go on and on with all improvements I came up with and incorporated on the 535 Cheetah I built, and I know that a lot of guys will say that a lot of the stuff I did was unnecessary, over kill, or pointless but everything came together nice towards the end. I've seen a substantial improvement with some of the mods I did and some I didn't see produce any noticeable improvement, but none of them had any negative effects.

How do you like the intelajet?

I like it, it works very well. The Intelajet System feeds a metered stream of pre-atomized fuel/air; like a fuel injector VS a metered stream of raw fuel only like other power jets available on the market today.

Thacker have you reach out to his brothers for some possible resolving of this situation? I googled the last name and it appears he's the least normal looking one of the bunch.

I contacted Ron right after everything happened and he said he was planning on building a big set of pipes for a new snowmobile he just bought and he would build me a custom set of pipes when he did his, but summer came and went and I never heard anything. I did get to see the Hydro-Forming Process that Ron used and perfected back when he was building custom pipes and his business was in full swing and I engineered and paid for 90% of what was required in order to build custom pipes. A matter a fact I'm the only person that blew up a pipe the entire three months he was out here. So theoretically If I wanted to take the time to do it I could build my own set set of pipes. I might give it a try someday after I'm caught up and I don't have so much other stuff going on.

IF I was to have a set of pipes built specific for some shit show I was building I'd start with Arlen. He's in my backyard, wait, that's not a good analogy......... He's local to me, and his shit works. If he couldn't do it for whatever reason I'd probably reach out to CPI as they have done some very specific sled stuff for me. If they couldn't handle it, I'd rethink my needs.

I'm not disputing that Arlen doesn't make a great two stroke pipe, he's probably the best out there right now, but I don't know how well his pipes would perform and hold up where I ride.

 

I educated myself and did a lot of in depth research on two stroke expansion chamber designs when I was working with Tom and regardless of everything that Tom ended up doing to me I still feel very confident that his brother Ron Borrink was in class by himself when he was in the pipe building game. One of the main things that I feel gave his Pipes a distinct advantage over all the other pipe builders before after him was the hydro-forming method that he developed, perfected, and used to build his pipes.

 

The exhaust rarefaction and pulse waves travel around the walls of the expansion chamber at the same rate or close to the same rate that the engine is turning. These pulse waves carry the unused "scavenged" fuel that escaped though the exhaust port and into the pipe on the previous piston up stroke back up to the exhaust port where it's pushed back into the cylinder combustion chamber and mixed with the fresh fuel air charge that entered the engine where the fuel is ignited and the scavenging process starts over.

 

Every weld seam will cause cause a tiny disturbance in the pulse waves that travel along the inner walls of the expansion chamber therefore effecting the rotation speed of the pulse waves which directly effects a two stroke pipes performance. I'm sure the weld seams are accounted for when the pipe is designed but it seems to me a pipe that has a smooth expansion chamber that's free of obstructions would effectively scavenge fuel better at a much more consistent rate.

 

See diagram attached bellow:

I think FTZ Racing is capable of designing and building a set of their Super Fat Inframe Pipes for the Banshee that would compliment a the PV Cheetah and work very well. I need to contact FTZ, SCP, and Sniper and give them the specifics on my motor and what I do with it and get them to give me a price quote on a custom set of chrome plated BB PV Pipes, Stingers, and Silencers and get their input on my options and which one will work best for me.

Two thoughts.

No amount of engineering thought, theory, and Internet diagrams is gonna change the fact that LED's hand made stuff is capable of crushing an out of the box stamped options with smooth interiors. Look at the dynos.

 

Second being that LED = LRD. We both know they dug their trenches in the GNCC world and dominated.
