Actually the I was not refering to port closing, I was referring to cutting the bridge port down through the plate towards the port inlet at a slight angle. Your bridge iron is actually thicker than most I've seen. I just added that by leaving it thicker and shaping it you can benefit. It also seems to me that most bridge's I have seen are cut at a 90 to the runner and it doesn't seem right.



Basically I just put the info out there for everyone. I can't stand when people don't share info. I run across this alot in Japan.



The chicken comment was all in fun. Whenever I port something I always have someone calling me a chicken(Dragon and a couple of others not on the forum).



As a side note, all these people that say the secondary bridge is not going to drive as nice, you are way wrong. My car actually made more low to midrange torque with the bridge than with the side. The only reason I don't have one now is because they are to damn loud for the cops and my neighbors.
Ok. I must've misread part of your post, then.



On the bridgeport 90 degree cut, I absolutely agree with you in the gut feeling you've got in how it does seem wrong. With regard to fluid mechanics, it's most definitely wrong. I suppose the best way to do it would be to use a press to cut the bridgeport cut itself at an angle, similar to that of the port outlet. This is why I taper and wedge the underside of the iron (just below the water jacket o-ring land) prior to the bridgeport cut to help make it 'catch more air' as you suggested in your prior post.



I figured you were playing around with the chicken comment. I do stuff like that here w/ my friends all the time.



You know, alot of those naysayer types are the guys that have never done it and have no reason or technical knowledge to back-up what they say. I've run into it so many times myself with all sorts of things:



- "that air to water intercooler won't work. it's not streetable."

- "that turbo combination is too large and won't work for drag or make power."

- "you can't make a bridgeport streetable w/ a turbo".



Baloney!

I actually use a hand drill to the same effect.



What turbo is going on this setup and what is the target?

I'm not sure what turbo Rob's going to be using. I think he's got a TO4S derivative at the moment but I told him it'd be too peaky up high and run out of steam.



Power goal? Good question...

Thanks, amigo.



I really need to buy one. I've been eyeballing one on Harbour Freight but I'm not sure if it's too cheap or not. Got any suggestions on a good one I can save my pennies up for?

The Harbor frieght unit is decent. You can pop out the cheap chineese bearings in the drill head and replace them with some decent ones, Scalliwag has done it.



PS did you ask scalliwag about the press pieces for me?

I haven't talked to Mike since you and I talked last night. He had to go to bed early; he's one of those types that has an 8 to 5 day job.

Igy;s talking about cutting it like this.. and not like the second drawing.. The second drawing is the way you will see most bridge ports cut even though that way sucks and won't produce the power that could be had if the port was cut the right way..



LOL.. this was a really quick pic...

Absolutely agreed and good illustration even if it was a 5 minute job. The picture illustrates well how the cut itself needs to be drilled and made initially.
