Does anybody have a Bridge port, running a T-78?? What port would you perfer for max HP on a T-78? Everybody talks about street ports, but no bridge ports, wouldn't that be more fuel/air = more HP over a aggressive street port???

I think with a turbo that big you should be able to get away with a bridge.

Sice your in so cal just try to give xs engineering(714)698-8300 a call they build and tune rotaries ask them what they think.

They do good work.

Pro's, You get more HP out of your engine. Con's, You reduce the live and driveability of the car. I know guys that have "driven" bridgeport fd's in he past as daily drivers, but I wouldn't consider them practicle. I say driven instead of drive because both of the fd's i'm thinking of have had different motor's put in since the original bridgeported motors.

go with a large streetport..... then, you wont have to change blocks every 10k miles!

That's what I decided on going with. Anybody have a rear housings for sale(4 port)??

I would recomend u go for a "Torque port". It's street port that is ported for Torque. I have tried both and Torque is the best. U get more low end power, compeard to a laaarge streetport that will give u more top end power.

I like to have it all over the rpm range, and not just on the top.

i have a bridgeport with a T51...i would go with the large streetport if i were you, more streetability, and much easier to tune....we are still having problems getting mine to run smoothly.

what does a "torque port" look like?

jantore

Well im not sure, but u should ask the guy that ported my engine

Changing housings every 10k miles is quite an understatement. Bridgeporting doesn't reduce the life of your engine that significantly unless you are just beating the hell out of it, which has no relation to the port. Yes they will wear out quicker. I would consider going with a 1/2 bridge. The port one of the plates on each rotor, so that you maintain greater driveability and also gain a significant advantage over a streetport. It will spool the T-78 a lot quicker than a streetport, and won't limit you in the top end.

I agree. The only difference, I believe, between an aggressive street port and a bridge port is the flow area. In terms of driveability, an aggessive street port could be just as driveable as a bridge port. There are other ways besides porting that can help spool your T-78.
