Good Lord, Bruce.. 60mb mpg???? I'm downloading it now. I hope it's cool. :)

I'm still not sold on big, huge bridgeports. I think what you've got now works pretty well, but if you want to try a larger spec, let me know.

I agree, half bridge is the best for street use

Sorry for the size! I hear bigger is better?

By the way, I couldn't get the video clip to work.

Are you running Divx?

BDC 10-10-04 11:45 PM

Took some better videos today. Give them a look, guys. Should be much brighter and easier to see.

No sound. Which codec are you using?

wankel510 10-11-04 03:49 PM

How much would it cost to put together a complete motor like yours? The sound is amazing, throttle response looks sick, and you seem to have a great reputation on here. I'm looking for the motor itself, normally I guess you'd call it the shortblock?

I used Divx, worked fine

Jeff20B 10-11-04 11:30 PM

Which version?

Why do you keep dodging the how much hp question and just answer the ones that suit you? If you haven't had it on a dyno just say I haven't had it on a dyno.

I am just curious as I have a full bridge turbo set up and wonder why you didn't go that way.

I'm not dodging a thing. I haven't had mine on a dyno. I have to parts of the powerplant I still need setup.

Just a question for thought: How does a half-bridge compare to a semi pp in terms of power, reliability, powerband, and streetability? I am considering doing one of them when I rebuild my motor, but not sure which one yet.

Thanks,
Aaron

I have not drive a semi pp car, but I have a half bridge car and it is very addictive. I am currently running a very small single turbo, just a TO4E 50 trim, but it has a great powerband and the sound of it is just pure sex. Prepare to spend lots of timing tuning it, that's a given, but it's so worth it in the end.

half bridge idle
 
I recently rebuild my fd engine with new apex seals and new spring and a half bridge....the car was very hard to start and when it does start it idles at 3000+ rpm....if u drop the idle it will die and would be very hard to start back...i am running a pfc ecu...I drove it a few times like this but if I put some more miles on the engine would the idle level off with out cutting off? is this situation normal?

cBigganz 08-18-14 12:02 PM

That does not sounds normal. You should start a new thread for your issue. This one is 10 years old.

You have low compression, nothing related to the port. The idle is also a huge vacuum leak, or poorly adjusted throttle. Once again, nothing related to your port.

Thanks...i guess i just have to put some more miles on it....

t-von 09-06-14 12:47 PM

I would check the compression. You did face the small piece of the apex seals away from the bridge in the rear housing right?
