Rough guess without knowing the jet on the carbs and what sort of engine back you have going, I'd say 140-160 no problem.

bridgeporting is no good for daily driving.. unless u wanna spend 20 dollars a day on fuel..


just go with 12a turbo.. mild port.. and a full rb exhaust plus the extras.. rats nest, electric fan, ngk spark plugs etc..

youll have a more fun car to drive.. trust me

oh and if not FI, then a weber48 ida would be the best carb to use..


oh plus 50hp of NOS.. (not kidding)

only when needed..

that should be able to keep up or beat most honda ricers out there..

cheers

To the guy who said 160: you can get 160 on a MILD STREETPORT with RB exhaust.

I'd say you're definitely looking over the 200hp mark, though where I'm not sure. If it's going to be a street driver, you probably want to go with a large street port, because bridgies idle at like 2k and don't drive that well on the street. Good for track though.

12a engine - good choice

Bridgeport - already commented on

Sterling Carb - flows PLENTY for any port you could think of, again good choice

Insulated Intake - not really necessary.. Gives like 1hp, but if you're going full out, there's no reason not to I guess...

Engine-Back Exhaust - you want to go www.racingbeat.com "street port exhaust system". It'll flow more than enough for any port config pretty much. Just the RB exhaust on a stocker alone gives 25hp, which increases with your porting.

DLIDFIS - your engine will run smoother and burn a little less gas. Not much hp improvement, but a great mod. Stronger spark is always good

Rat's Nest Removal - again, like 1hp, but for reliability and stability, it's a great mod

E-fan - a couple hp, cleans up the engine bay, and can be set on a variable-temp thermostat, very useful.


The big things there that will affect hp will be the porting, the exhaust and the carb. I figure you can probably get at LEAST 200 with a large street port, sterling carb and exhaust alone. From there, a larger port or turbo ups the power (I'd go turbo, more drivability), and the sky's the limit.

Anyone else wanna add to this?

I have to disagree The racing beat streetport exhaust is mean for stock or streetported motors. A bridgeport does best when there it as little restriction as possible. ie dumping out the header. By putting this exhaust on it you will restrict power alot.

Dual 2.5" all the way to the muffler... I figured it'd be enough for even a bridgy. Didn't think it'd offer alot of restriction, and if this is going to be a road car, you *have* to have presilencers and a good muffler.

If it's a track car, dump out at the headers, get a megaphone, and go crazy.

I did say pending answers to jet and exhaust didn't I? I don't care if you took it in to FC3S.org and had Craig and Dave monster port it as much as it can go, if the exhaust is too restrictive you'll never see past 160. Plus the jet on the carb has to be right etc. Yes a bridgeport is CAPABLE of 240 and then some, but only in conjunction with proper tuning of everything else. There isn't one magic piece that makes your car a god.
Now, reassessment given more facts... I'd give it 220.
