[quote name='Newguy707' date='Aug 30 2005, 07:58 AM']I don't know the racing class rules, but that sounds weird. Would the only "legal" way be to grind the N/A diffusers out? https://www.nopistons.com/forums/pub...1047683358.gif I would think the housings are equivalent to a piston engine's cylinders, which are the same between N/A's and turbo's, right?



Ahhh, the joys of all the rules against the rotary engine...



Why don't they just ban the rotary completely? ...Like they did in the 24 Hours of Le mans... Punny piston lovers!

Within the confines of the SCCA's rules for ITS the only legal thing to do is use the unmodified NA housings. I'm sure other classes and other sanctioning bodies have different rules. But j9fd3s specifically referred to ITS.

Ahhhh like the old saying "It ain't cheating if you don't get caught" people have been adhearing to that rule since the beginings of automotive racing.

yep, but we run nasa, and didnt have any good na housings

we run nasa, ps1 is the class which is supposed to be the same as its, but nasa doesnt print rules so we dont know.

What's wrong with running sp or gt-1?

lol, well other than that aspect!



back in the 90's most of the rotary guys in this region were running gt-3 and were out of control, to say the least.

I'm not trying to be an ass but you could certainly be leading some people down the wrong path. The NASA rules are published ( http://www.nasaproracing.com/rules/ps.pdf ) and the intent of the PS rules is to adhere to the SCCA ITCS except where exceptions are made by NASA. This particular part is not one of them. Your engine is illegal for NASA PS-1 as well.
