Hey guys i was on the xtreme rotaries website yesterday and they have a video of a 13b bridgeport making over 350 hp on.
My question is do they make 12a bp's and if so how much hp are they making.
Does anyone on here have a x bridgeport 12a or 13b,if so what do they have and how much did it cost to build?
I know i could just ring and ask but i want some feed back from previous customers and not just a sales pitch from the builders themselves
cheers

Hi Mate,

Yes they can BP a 12A and if you use the search you should find heaps of info on these combo's.

In short the HP figure you quote seems "suspekt" for a n/a BP, most would be making about 100HP less at the motor from my experience.

These motors are full on IPRA spec racing motors, running quad throttle bodies, and do like a rev to make these hp figures.

13B BP's were punching out a genuine 310+ at the flywheel 15 years ago in this class of racing, and have only gotten more powerful from there.

Your average decent street 13B BP with a Weber will make by comparison 230-260hp at the flywheel by comparison, but that's comparing apples to oranges.

Rohan's motors have consistently been making top hp for a long time, and his IPRA RX-7 held class lap records all around the country, so we aren't talking about some Johnny come lately backyarder here.

Fair enough then, hope you have deep pockets suspek!

Get in contact with Jed (buzzme)
The figures are correct from what I've heard
Jed is pulling good power out of carby fed 12a bridgeys 210-220rwhp
And to top it off a very good bloke
Jed and Rohan were having a comp to see who could pull the most power out of an na
I will have to ask if its still on next time I see him

Big HP 12A Bridgeport??

Matt Russell Race Engines.. The performance on the track speaks for itself.

Word of advice, if you are chasing big HP it will cost.. Remember the old mantra - you get what you pay for.

Go well?


Go Jed.
