Hey guys,

I'm going to have Jerry Hall build me a inframe pipe for my dune ported 363 sphynx, were looking to find as many pipes as possible that guys say works good on the sphynx to see how the engine responds to different pipe dimensions. You can ship it straight to Jerry's shop in Phoenix,AZ. As long as it cool with Jerry all dyno info will be posted. I'll pay Shipping and can give you some extra for the help. Let me know if any of you guys can help me out.

Thanks,
Mike

If you are paying for shipping then I probably have a inframe FTZ drag pipe I can send, I will even let Jerry cut the end of the stinger off that necks down from 1-1/4 to 1-1/8 for the stock silencer. that way both stinger sizes can be compared

I may be able to help out with a shearer sphynx out of frame depending on when..

That would be awesome, I can pay shipping no problem. It problably won't be for another month. Its so dry up here in Northern Arizona their going to shut the forest down real soon, so I'm trying to get as much riding done as possible now.

That be awesome, I probably won't even get my bike down to Jerry until after Memorial Day so maybe in a month or so. Let me know if that will work for you.

That probably will be bad timing for us and Mr250sx since our season is just winding up

I have a Sparks MX that you can borrow, it's all clapped out but will work for your needs. Although you might blow up the 363 with this small of a stinger and header diameter lol

I have got a couple old LRD pipes that came with the last 250R I bought. They're standard stinger. But if you'd like to run those, then just let me know.

I am in Phoenix and have an ESR TRX 11 CM and an LRD Team B you can borrow for the day if interested, although both are standard stinger size.

I have A TRX11...It's an out of frame pipe but should work for what you are wanting to do.....Let me know

The TRX5, TRX9, TRX11 will probably fry the piston if the sphynx is trying to make more than about 55 hp on my dyno unless they have the 1 1/4 18 gage stinger and silencer.

These big bore engines need the large stinger with the larger through hole in the silencer core. Any of the 250 pipes with the 1 1/8 od 18 gage stingers and through holes in the silencer will also be two small and will also hurt a piston.

We need a selection of pipes that are big bore pipes or 250 pipes with big bore stingers and silencers.

When I had Mat Shearer build me a 370 Sphynx a couple years back I was on the fence about what build I wanted.... Dune port on gas, or drag port on methanol. He said for the dune/gas motor I would be able to get away with a Trx-5 CM pipe, he actually complimented that pipe very well stating it's the best "off the shelf" pipe he's tested. I ended up doing a drag build and went with a shearer OOF. Just thought that was interesting.

Not sure what your saying here...Maybe my ESR 350 cylinder does not qualify for Big Bore Status but I have run it and run it hard for over 4 years and never had any piston problems running the TRX11 straight from ESR....It might have something to do with my complete package as the cylinder and cases were both modified...Either that or I'm just lucky?
