Another chainsaw dyno...

[srcarr52]

I’ve had a few vent issues with TRX 450s, I bet you pick up some HP just fixing that! Are you by any chance trying Q16?

No a friend became a Renegade fuel dealer so we can all run the SX4+ for cheaper. I was running VP T4. Plus it sounds like we might have 3 turbo bikes to take snow biking this year which will all need 110.

Yeah, it's just two 5/16" holes covered by a stainless reed for the crankcase vent. One of the holes only partially opens due to the reed limiter, I'll be cutting the bridge out between them and probably doubling the amount of air let out from under the piston into the rest of the case. Hopefully that will stop the oil belching from the vent and help with ring seal.

I haven't got it torn down far enough yet to tell but I bet it pushed the right side crankshaft seal out. Then the case pressure relieves into the gear case and wont let the oil drain down from the head. Then the oil escapes out the breather into the air box and you have a smoke machine!

Had county fair this week.

One of the higher placing pigs we sold. Reserve champ in his weight devision.

Had 3 pigs in the top 16 out of 150+ pigs
12 sold/shown at the fair all 5th in class or better.

But back to the saws/dyno now.

Fat!

 

[Red97]

Fat!

Ahh, he was only 270...

The trend is more towards the porky massive pigs.

No wonder he won. Just about perfect. When I get back to pigs they will have white points. If I have my way. She is stuck on mangalitsas or the little kune kunes. It will be much smaller than your operation and probably a lot of pasture.

[dustinwilt68]

390 stock is 6.5hp, that's a little over a 40% gain at 9.2hp.

 

[RI Chevy]

Wow. That's a decent gain there!

 

[PA Dan]

That Rattler venom is potent!

 

[RI Chevy]

Yes. Some strong recipes for sure. [emoji106]

 

[Red97]

Have a stock 500i coming to play on the dyno.

Need to get a stock 390 now.

Only ported 390,and a ported 500i so far.

 

[Red97]

Ported
390 vs 500i



Feel these 2 saws could go either way.

 

[Woodpecker]

That 500xs impressed the heck out of me when I ran it last year

 

[MustangMike]

Could not get any closer if they were both the same model ported by different guys!
