As long as you can use 2xxx series pipes in sanctioned events I would not touch anything starting with 3. They restrict way too much and even if there is better economy in some cases the lack of power pretty much destroys the benefit. Problems with the 3xxx series was the reason EFRA re-approved the 2xxx series

Thanks Brian, glad that you were impressed with the motors that you got to see! We put a lot of time into developing it and I really think that when it comes to bang for your buck there is no better value on the market at this time!

Hi All,
I've just got my B5 this week and getting ready to break it in. It's going in to a D8 and i'll probably start with the stock carbon clutch and 1.0 springs and then try vp-pro aluminium shoes with different springs.
Before installing the B5 should i take it apart and flush it out and then re-oil it. I was just thinking to take the head off and back plate and flush it out that way.
The other thing should I seal it up straight away? I've done that in the past maybe not straight away but after the first tear down and inspection.
Do you need to replace the con-rod after break in?
I'm not sure which pipe to run with have three to choose from Dyn 086, Go 0801 and Go 2072. I'm thinking the 2072 it's been pretty good on the Go engines i have.
Any way looking forward to running the B5.

Sorry, forgot to get back to you about this yesterday. Regarding the pipe extender, this was only made for (and included in) the 2057 pipe set, not the 2013. These are not sold as stand alone's and honestly I'm not sure why you would want to run one on the 2013, that pipe makes PLENTY of bottom end already lol! In this case I'm going to have to say you don't need it, even if you could find one save your money.

Poinas2 hit the nail on the head with his comments (thanks!). The 3014 will really smooth out the power band on the B5 and also increase the run time. However it's going to do this by being a ton more restrictive. As long as you can get away with using the 2000 series pipes as he mentioned I would probably recommend that you stick with them (unless you are for instance running on a small, super slick track or something). The 2057 or 2056 are in my opinion much better choices which will give you similar run times but with superior performance. Hope this helps!

Thanks Ron for the reply. I won't seal it straight away or flush it out, it looks pretty clean right now. Thanks for the tip about the back plate and the piston.
Anyone that's running a D8 what thickness shims have you used between the flywheel collet and front bearing? I've just tried with out any quickly and flywheel rubs top of crank case where the car inserts. The shims I've got now are 7x12mm are these okay to use or the OD is too large?
thanks
Jason.

HI Guys,
Found some shims for the flywheel collet. Using a 7x10mm shim from the ofna clutch shim it's 1 mm thick and another 7x12m shim for a total thickness of 1.5mm. Tried only using the 1mm shim but it looks like the flywheel was a little close to the carb.
Can I ask what other people with a D8 have done?
