Bryan,
Yep! that's what I've heard as= well.

George,

The side seal tolerances are many times greater than th= e traditional seals. =A0Plus they have a =93keystone=94 shape to them.=A0 I= have heard that many racers use the longer seals in an attempt to close th= at gap.

Bryan an= d Jeff,=

I have s= poken to a number of people about the Renensis and they all tell me that no= ne of the compression seal sizes( lengths) completely seal against blow-by,= hence the need for the extra O-ring type seal in the rotor sides. <= /font>

=A0

There ar= e a number of lengths available and it has been suggest to me to use the lo= ngest, as at our usage, as compared to racing,=A0 their never going to reac= h their maximum length. Their length is governed by the fact that=A0their b= eing more exposed the exhaust heat, because of the side exhausts. It's = my feeling that that little cut away in the exhaust side ( of the rotor) ma= kes them even more exposed.

I hope t= hat makes sense.

George (= down under)

=A0Jeff,

The grooves for the outer water jackets are in the roto= r housings vice the side housings.

The rotors have an additional outer ring.=A0 Some of th= e tolerances are not in the DVD due to the fact that these components are u= nique to the Renesis.

I can get those to you if you decide on the Renesis.=A0= Otherwise, pretty much the same.
