it might look impresive but how does it drive ? no good making peak power 2000rpm after your engines blown due to being over revved !

Hmmm I reckon it wouldnt let too much moer fule/air in thana decent sized PP though? would it. Most big ported rotors, whether they be bridgies, J-ports or PP\'s usually idle very high compared to stock/mild port and they rev to the heavens if built well enough. i.e 10,000-11,000rpm.

Title: looks like somebody has got some 6 port bridgeport templates for me....
Post by: MikeLMR on May 24, 2006, 08:14:23 PM
Isn\'t it more down to port timing rather than size, I think that 6 port will close very late and open really early due to the bridge (I quite can\'t picture it in my head without searching for that website with all the ports drawn out with the rotor edges on it at open and close)

The brapping and poor idle is all down to the ehaust and inlet overlap, basically *I think*  Is the noise down to exhaust gas trying to escape out the inlet port or have I got completely the wrong end of the stick ?

I suppose it makes less odds at higher rpm\'s as you will have a pressure wave sucking the exhaust products out and a positive one pushing the mixture in

^ just thinking out loud .... anyone else know what really goes on and explain it ?

Look a good port job but it\'s better not to port a bridge, bridge look too long ,will collapse due to sonic vibrant.(spelling?? ).
Correct me if  i am wrong!

Bridge can be incredibly thin, it\'s the depth that will kill it. Anyway... PP + Nitro, like we were saying on the phone. Picture (http://www.mazdatrix.com/pictures/racing/r19-1.jpg)

Have a guess how much hp that 6 port bridge put out at the wheels...
Title: looks like somebody has got some 6 port bridgeport templates for me....
Post by: dubber91 on May 25, 2006, 06:45:10 PM
246bhp@7600rpm
Title: looks like somebody has got some 6 port bridgeport templates for me....
Post by: travellinbob on May 25, 2006, 06:54:00 PM
At the wheels, I reckon 180hp.
 so when do we find out???

Remember that an engine loses roughly 30% of its power through the drive train so 180 at the wheels in a lightish car is pretty good.

It\'s never been dynoed but here\'s what the owner told me about it....

hey mate, my friend who built the DAFF1E DX he originaly had a 6port bridgeport before his pp. his ports were slightly smaller than mine and he had 226hp at the wheels with an ida
his pp had 239at the wheels,

so mine would have been some where in between i would guess
but i never had mine dynoed

It seems daft to bridge port a 6 port when a 4 port bridgy done properly makes  more power.
