Powefactor on small cc

[tipafew]

I am running a cast 7 port Lamey 5 mill stroker. 771 cc.
Curious if anyone has feedback on a similar motor as to what they saw when comparing PFP to B pipe. Is it worth it??

I have a lamey 8 mm 865 cc love the pfp with water injection, have not run it on a b pipe.

In general it will work, dry is mid to top, youll lose bottom end hit of b pipe, injected youll keep bottom end and lose top of dry.

Unless you run ECWI.

So basically not much different than any other dry pipe. My old race skis I ran Speedwerx dry pipe and Type 9. What is the big advantage over those beyond weight??
It doesn't sound like anybody is trying to talk me into making the switch........

the biggest advantage is that the PFP is a laydown pipe which make sit easier to work on the ski as the pipe is rarely in the way. And if you are flipping the weight is supported by the hull not the block. As for performance gains are all in the tuning between a SW/T9/PFP

I had a cast 8mm Lamey motor back in the day, 803cc, that I had one of the first PowerFactor's on.

Ran dry / no injection, along with MSD Total Loss.

Loved it over the Bpipe.

100% worth it, IMO.

Bottom around the same, but stronger mid-pull. Another selling point to me was Power Valve clearance. The Bpipe back in the day had to be all sorts of hacked up to clear (before the days of low profile valves / Bpipe spacers).

One thing to take into consider also on the cylinder, is the cooling trench on the exhaust post.

My cast cylinder would not have worked properly had we not modified it (I gave it to a local machine shop and they trenched it for me).

Here is that setup in my Rickter FS-1 back in 2009.

I had a PFP on JM781 a few years back with TL it was great IMO

Unless i was over powered, not sure that can happen, and riding strictly surf, wanted a 5 gal tank or larger, lay down is the way to go, more power everywhere if tuned properly IMO. Not referencing the other pipes mentioned here, as we have been having great results in the group with other Type 9 style pipes. Again PV issues, hood clearance, etc.

Run my wife's PHP760 on PFP wet setup. It runs great. Wouldn't even question a bpipe for it.

 

[Christian_83]

Ran a Dasa SS 850 with MSD TL, dual FS 49 in a carbon lens superjet hull, first with a b pipe, then switched to PFP. A little less off ilde bottom snap with the PFP, but overall much stronger.
You could make the switch to any dry pipe, but as @DAG pointed out, most aftermarket hulls only accept lay day pipes.

I am looking for a type 9 if anyone wants to move one

I saw video of you flipping that thing. Looks like it runs good.

Never would have thought of that.

Never would have thought of that.

I didn't either, until about 2 days before I was started to assemble everything...

I lined everything up and thought to myself "hmmmm this isn't quite right". I put a gasket on the cylinder as the template, colored it with red sharpie where the trench should be then drove to the machine shop. Think they charged me like $50 to program and knock it out real quick. Pretty cool of 'em.
