Rusty,

In response:-

The 38mm is for dirt racing not = track, he=20 suggested this was the best all round size, but has a hesitation at = around=20 4,000 to 4,500,

which he is yet to identify the = cause.

What RPM are they running during the races? =20

Top of 8,000 to 9,000 = - which=20 coincides with Jerry figures.

I hoping for 115 to 125hp at = 7,500 rpm, I=20 think that's achievable!

Isn't it also achievable with the stock = Renesis=20 housing? Why make this harder than it needs to=20 be?

Is it achievable in a single rotor = ?- well your=20 telling the story!

However I will take what I can get, if it's = more.

You tend to forget some very important = points Rusty,=20 please remember I'm working on aluminium end/side housings (=20 without ports) - so too is Richard Sohn. It is much easier and = cheaper to=20 do it that way. So naturally we need a port=20 somewhere.

I following your advice ' why make it = harder=20 than it needs to be".
