Running 112 octane so should not be any detonation.
One mans season could be another mans month on engine hours.
Piston wear is also an issue due to availability. Riva still make an 85mm flat top but 85.5 and 86.5 have been discontinued by riva and R&D. Not sure how long pistons will last...
I tied chamber back to cases with heavy zip tie around stinger , back to en eyelet bolted to flywheel cover. Also put a block of rubber below hose going to water box to support chamber and keep hose from pulling it down. Could also resort to springs if needed. Would need to weld small ring on...
This pipe is awesome. Gonna have to go up some more on prop pitch. Snaps out of the hole hard with strong power all the way to 7550 RPMs. Hit 64mph with a skat swirl. Gonna stick the big hub concord in it and see what it does. In the past it was a couple mph faster than a swirl. Never had a...
You sure can any time. If it wasn't for you I wouldn't even have this motor or have bought one of the other three in existence. Will be sending the second motor to judge soon for lo profile PV update and 85mm setup. The second motor will eventually be installed in Hydro hull if and when the...
It fits very nicely in the 08 + SJ hull. I could see where pipe may hit hull on old style hull. Newer hull is wider below bond line. This pipe makes plenty of RPMs. No need for dry pipe. This ski is running close to 65mph. Plenty fast for a standup
Chamber stayed together today. Ran a heavy zip tie round tinged back o an eyelet bolted to flywheel cover. Also put a block of glued turf below outlet hose to keep it from pulling on chamber. Not that I didn't expect it to , but pipe works well. Pulls hard and revs . To rough for tach testing...
Had a TBM Grate on SXR for 8 years and recently switched to R&D Stealth . Had to cut the wings off so it would fit in Skat pump shoe . Like stealth better than TBM as it hooks up better .
I have not quite gotten around to installing this 144 yet . Expect to within next couple of weeks . Have no doubt it will work very well . The come tapped for 1/4 NPT which is the larger size fitting . Currently running a 140 skat mag that is flawless but am almost maxxed out on prop pitches...
Chamber barely clears stock tank . It clears it but no room to spare . Planned on doing tach test with pet 2100 and putting GPS on it , but due to chamber popping out did not . Last Sunday this ski did 62mph with Bpipe , LTD chamber with Xscream stinger mod .
It is Judge ported 8MM cast...
I used the stock hose and spliced in a section of tube so it would reach . I am thinking the reason chamber popped out is because this hose is pulling on chamber . It needs to be supported off floor of hull and chamber needs to be tied back to motor .
Thaere is no way I would take this...
First of all , in the shorft time I rode it yesterday I could tell right away it makes good power .
I have to work on something to keep the chamber from popping out of the headpipe . It never made it more thnan one minute before it popped out . One of the rfeasons the Bpipe is so...
Big hub Concords used to be rare . I've had one for over 10 years in a 140 mag pump They just came out with a new run of them in the 144 size. Impros has them .
In addition to compression ratio , you have to consider ignition timing as well as rpms ski will be run at . Are you going to hold it wide open accross the lake , or will you be putting around jumping waves . Compression guage readings are good for monitoring engine wear .Check it when its new...
Alright , I just ordered one. Of these Chambers. Will see how it does in a Kawi Dasa 4mm stroker . May also throw in in a Superjet with 8mm cast Dasa and see what it does in there .
