Our ligthen rotors

Here is a pic of our lighten and balance rotor going in one of a built semi-port motor

How much weight did you remove? It looks like they were just barely "lightened" for balancing purposes..

Maybe post up data for before/after of both the lightening and balancing?

What series rotor?

there's more weight removed on the face, didn't take a pic

it's about 70 thousand taken off, not that much in lower the compression, we are going to run 40 plus pound of boost on this motor with E85

sounds like you need the best apex seals...........

For sure in my next built

Not to be a dick or trash on you at all. Genuine concern.

Now isn't where you took all that material from going to interfere with engine operation?

Is that lowering compression? How much?

Anyone else any thoughts on that?

At dead center the chamber splits into 2 and forces the fuel air mixture through the exclusion to be ignited no? Would doing away with the exclusion ignite leading and trailing at once?

Also can it come away from the shaft like that?

You realise the tub in a standard rotor joins the two ignition points with a far larger/better flame path than any face machining ever will right? Any difference around the sides of the tub is inconsequential in terms of flame path vs the tub itself.

My concern is taking the weaker of the rotor series and removing material close to where they're very thin and like to dent anyway.

No concerns on this method! it was done by 2 well know shops

***TitaniumTT*** · 03-10-2015, 02:00 PM

Ah, so it's not actually your machine work?

So who did the work? By the way you initially presented this it sounded like YOU did the work involved, as opposed to contracting out to another shop.

Give credit where it's due man!!!

Goopy I'm guessing. The big boost PR cars do this to provide clearance between the rotor face and the housing. It's not about lightening the rotor. If you really wanted to lighten it, you'd also mill the sides.
