Powderfreak Head

[powderfreak]

Combined with full exhaust set up could be a total around 25hp...?

Hi Guys, Duane here from Powder Freaks. Glad to see the interest in the 850 head. Snow is building up in the mtns now. I expect guys will be getting out and trying out the heads very soon. Look forward to seeing the posts guys put up. I will be doing some dyno testing very soon with a few different pipes to see how they work with the head. I have a dyno port pipe, NPP pipe and a Jaws pipe coming and will post results on my FB page. Lots of guys still skeptical and I get that. Have 1 more independent dyno test coming just for the remaining unbelievers out there. Look forward to seeing all the 850's with my head up on the mtns this winter. Any turbo 850 guys out there that would be interested in trying my turbo bb give me a shout. Funnest sled I have ever ridden.

Post some long pull dyno runs when you do the tests. You have us all curious and wondering.

These numbers are starting to look a lot like the old HP claims from years ago.

I would like to see real world numbers, that’s what I care about really, legit no bull info. What does it look like in the 75-wot range, that’s what I’d like to see the numbers for. And a Big Bore Turbo sled...Landon loves his Big Bore, swore by it, and I love my turbos.

BB Turbo.....sounds like a good time...

Thanks for the reply and the info!

See Dyno sheets from NPP
LEft is head only, right is stock

 

[Caper11]

Humm, am I reading that right. 164.4hp at 7700rpm????

 

[FastFarmer]

So possible to hit 180-185 then?

 

[pfi572]

Stock hp

 

[DRD]

Curious one run is -2F the other 50F.

 

[canuck5]

Pretty sure it’s 42 and 50

 

[DRD]

Yeah, think you are right. No one wants to dyno that cold unless they want some cold azz air.

 

[canuck5]

Cold dense air will defiantly make more power but -2f is -18c so it didn’t make sense to drag a dyno outside or have it in a freezer. Though it would have been an interesting way to fudge the numbers lol.

I’m very excited for the CTEC head numbers, I believe the gains will be just as large as the 850 doo gains. Great job Duane

 

[Rab123]

any more developments or reports from people who have tried this head ?

 

[SicLoco]

Rode mine yesterday and after adding a little weight to the clutching , it sure works good!

 

[eagles22]

How much weight did you have to add once you installed the head?
