looks like somebody has got some 6 port bridgeport templates for me....

[oldone]

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

My thoughts to M,...... :rollin

[travellinbob]

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.

That motor will def win the brapping sound off comp.......... :Typing

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 ?

My post was tongue in cheek bro.....sic sense of humour..... :evillaugh  :spank  :rollin

[MikeLMR]

I know ... but you got me thinking

[oldone]

That motor will be \'happy\' just to idle at 4000rpm,airflow will be pi$$ poor..... :Nono!

wow, this is turning into an informative thread for me....

Im sat quietly...ya wanna begin with the difficult stuff now?  :wave  :Hammer

Aint no dificult stuff bro.... :Nono!  just common sense... :cool

[dubber91]

yeah experience cant hurt tho bro  :p
i bow down to your jedi-master-like wisdom!

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!

yeah i beleive ya can go over the top if you, say, extend port a bridge....
bet its the same case for 6 ports when ya join them in the middle...

[mattmaclennan]

Bridge can be incredibly thin, it\'s the depth that will kill it. Anyway... PP + Nitro, like we were saying on the phone. Picture

[mullins]

Have a guess how much hp that 6 port bridge put out at the wheels...
