what ROF you pumpin with them 13:1’s?

It’s about 50 - 55 rps

Bump Bump Bump… Price drop. $350.00

Any proof of 50-55rps? That would take it into a dsg rof area.

Arent those red chi hai’s 30krpm @11.1v? That would technically put it in the 35-40rps area if everything is working sweet.

It’s the s460 black and red super speed&torque chaihai motor in there. It does about 37krpm. The tappet plate has also been modified to short stroke.

I dunno how to really test, I have run it through the chrono on the video. I’m not really sure though. Could be 45rps?

Ahh yep rightio. Yeah i think 40-45 would make sense but i dont think you would be in the 50-55rps area with that set up.

Have you got any photos of the modified tappet?? I’m doing a similar build that’s around 40rps so im interested in what changes were made to the tappet.:blush:

You should be able to set the chrono up so if you give it a burst of about 20rounds it should give you a rounds per minute then divide that by 60

That chrono should give you rps directly

Nice one! Might have to invest in one of those.

Whats the reason for the selling of this beast mate? Is it still for sale aswell?

Yeah mate. Still for sale.

Had it built a customer, they backed out, so have posted it here.
