Seeing your involved with rota's 20b??

Love the level of engineering that goes into your builds looking forward to seeing where this heads

NICE, an angry 20Bpp. And again a work of art. Will you be at time attack again this year?

350 to 400whp sounds good.

you gonna have a centre bearing on the shaft?

Yes I'll definitely be there in some capacity.

Hi James, with recent developments in this area it could possibly go well over the 400rwhp mark. A few weeks ago similar spec 20B PP made 520fwhp on 888 Racing's engine dyno! :twisted:

Time will tell what's achievable with my engine package.

I'm using a 20B block as opposed to an aftermarket 13B based triple rotor (short crank). I don't require an eccentric shaft bearing support between the second and third rotors...also you would require a custom eccentric shaft for this. As it will be naturally aspirated not too much engine strengthening is necessary...which is good in keeping the costs down!

Here's a Youtube video of a mate's 20B PP he built back in 2007 for his RX-2 sedan! Gotta love the free revving nature!

Cheers,
Danny

Yes, yes it is!

Probably not too good on a track with corners in this setup though! :lol:

Boostless! :twisted:

Ivan Mikac's 20B PP powered FC circuit race from the mid-2000's! :beer:

NICE!

Can't wait to hear the NC beast in action Danny, hope the build has found a new lease of life, it's certainly gained a whole new following!

Don't make me post a video of an ugly kiwi 323 with a 20b that sounds like an annoying chainsaw. :lol:

Thanks Peter. Yes the project certainly needed another kickstart. :oops:

Just gotta keep the momentum going.
