Higher port timing will cause wetpipe to rev higher than it typically would

Higher than a dry pipe?

Dry will be higher than wet on the same engine, what a pipe revs to depends on length and temp of pipe

lol which is it

Just like there two bpipes/sizes. Then tuned with water

Lets educate DAG
Numbers I'm using are for illustrative purposes only and not accurate
A drypipe will make the most power when built for the engine porting as it is stuffing more fresh mixture into the engine and has no water to dilute the kj per cc of mixture.
An engine with 200 Exh port duration and a wetpipe could rev higher vs an engine with 180 duration and drypipe.
High port engines can make power down low if fitted with a long/cold pipe. This is the reason that Tim doesn't recommend his pipe for DASA engines unless they are large cc, typically you would run a larger jet on DASA vs other lower port engines to compensate, but this means more water entering your engine.
The cc of your engine will contribute to determining pressure and heat in pipe, so a 701cc with the same porting as a 1000cc would typically need a smaller jet in a wetpipe. Carbs, reeds, etc will affect gas-flow too.
Ignition timing will affect heat in pipe, advancing timing at low revs cools the pipe so it acts as a longer pipe.
A difference in the size of an exh port(time-area) will also move where the powerband is on two same sized engines with the same exh port duration, so you can't rely on port timing to give the range of the powerband of a pipe on an engine.

There are a lot of variables that make a pipe/engine combo work, pipes should be sold with porting parameters. This is why I build my own pipes.

Just curious why are you contraticting my post about a wet pipe signing off earlyer for a dasa 888 with high port timing when you know all the information above?

Where does he state it is a high port motor? A race motor is not necessarily high port, width and radii of the port also affect rpm

I just guessed the port timing was higher. Spoke with the original builder of the motor and he said it was a podium race motor in world finals back in 05 06 07 and if I wanted to use it for freestyle I should remove the spacer plate to drop the cylinder and cut the domes to drop the ports down.

Be careful of cutting domes, they could crack while engine is running. How thick is the spacer plate? Check piston skirt when dropping cylinder, you might open crankcase to exh port when the piston is at TDC, you need at least 2mm overlap onto sleeve.
Pick a pipe, fit it and ride, then decide on mods to make it do what you want

 

[brad95]

For reference I run a rrp in my havoc. Its tight but does fit.

So decided just to go with a standard TNT manifold and v3 chamber. Its going to go on a ported out 701 for a while until I figure out what motor im gonna upgrade to eventually...the dasa is looking like more work than I want to deal with so trying to sell it off...

Good to hear you went with a TNT setup. Best choice I ever made after two PFP pipes, also helps because I have him a few hours away and is extremely helpful/knowledgeable. I have never had any issues with welds so maybe that was something with the V2 chamber since they had a lot more welding surface than the V3 that I run. Once you get familiar with the pipe and the jetting you will be able to slightly tune your setup and will make a difference to your riding. I think its a great beginner friendly pipe since you can run it more wet to give you the bottom end and then when wanting more power up high you dry out the pipe a bit.

 

[Ochocoronas]

Just out of curiosity... is a PFP and a RRP Carbon Pipe chamber interchangeable? I have a PFP now but would not mine trying an RRP chamber. Would I have to move the waterbox?

 

[OA5599]

The manifolds have different internal diameters, so with a RRP pipe you would have a very rough transition from mani to chamber.

 

[DAG]

You can punch out the RRP sleeve and run but typically best not to mix and match

RRP manifold does not have a sleeve anymore.

 

[Ochocoronas]

I am very happy with my PFP so I will just leave it alone. I was just seeing if I could try the RRP on the cheap. Oh well

Interesting, did they change the pipe flange or is there a huge transitioning step between the 2 now? Curious as to why they would remove the sleeve
