On a 12a?Thats nuts. rukh- your sig says rebuilt 12a.Why would you want to tear it down to port it?Rebuilds are expensive.Just wait till she blows up.Theres lots that can be done to any rotary before porting.Start with a simple header and exhaust swap.With all the little mods done to it you might even change your mind about porting it.[/quote]

hes probally not satisfied with his HP..im not.so porting and turbo next

I just got a magazine from as local race shop saturday...its called Drag Sport....and it has rotarys in it with Racing Beat cars in side...this is going by racing beats testing...

.................................................. ...........................

12A-- POWERBAND 13B-- 20B--

STREET PORT (220) 7-9K (250) (375)

BRIDGEPORT (260) 8-10K (290) (435)

PERIPHERALPORT (310) 8-10K (340) (510)

.................................................. ...........................

I know I have seen diffrent stats all over the net....BUT peopel uses diffrent size ports..and they didnt tell you what set up they ysed to test this...(Stock set up..or aftermarket)

The HP seems to be a little high ..and the Powerband range...btu this si from RacingBeat..

I've read that too.But when you port you are increasing the exhaust flow so yeah a muffler will stop that flow which would make it useless unless its a straight thru muffler.

Depends on the port job itself dunnit! Buddy has a B/P 13B in his gen 1 with a weber. Makes about 240, comes on at 3500, is MUCH faster with open pipe.

I had a PP 12A in an R100 years ago. Was flat & frustrating like a 2 stroke off the pipetill 5000 then went insane! Did about 8 mpg too

my friend has a bridgeport 13b in his rx3. it puts down 230rwhp@9500rpm (thats where the dyno stops), it isn't loud, its gets 23mpg (if you stay off it).

it does idle kinda roughly at 1500rpm and its powerband starts at about 5k.

its a car you could drive everyday, but you probably dont want to
