Well for anyone who is interested in 6 port bridgeport figures, the engine shown in the picture I posted finally got a run in tune today, it made 201rwhp at 6500rpm and 170ftlbs of torque at 6500rpm, the owner said they didn't take it above 6500rpm and all the figures were still on an up slope so it should have a bit more in it yet, I think they just want to put some miles on it before reving the crap out of it. Keep in mind this engine is a secondary pridgeport, it is using the factory manifold slightly modified and megasquirt ecu.

Ill post up the dyno chart when the owner emails it to me.

 

heres the dyno chart

 

^Thats not a bad looking chart! What happened to the rev range though?

 

What did you moddify on the manifold ? What exhaust set up has he got ? Cheers.

 

I asked the tuner about that and he said it flattened off at that but he also said that the owner turned up with the gas light on and it was running out of fuel before he got to tune it fully, so I don't really know, it looks to me like its still ramping up, anyway the owner is going to get it retuned in the future after he has run it in a bit so Ill post up a full rpm chart then.

 

With the manifold I removed all the valves that control the extra ports and filled the holes from the shafts then opened them up to match the engine ports and sharpened up the leading edges where the flow splits into the individual ports and generally rounded sharp edges and imperfections,

As far as the exhaust goes, extractors long primarys with a reso in each joined at the diff and then to 3" into a large muffler not sure on brands?

 

I just got emailed these pics of the exhaust

 

Awsome man, That exhaust look's good ... Loud ? Any vid's of the car running ?

 

Im in Nelson the car is in Auckland I have not even hear it running Ill try and get him to put a youtube video up

 

Heres a video of it running, yeah its pretty loud!

 

Sweet Is the exhaust one piece ? And what's the little pipe for off the front header ? Be interesting to see what it make's once the rev's start going up ...

 

Im not sure Ill ask him about the exhaust next time I here from him, I wanna see it opened up as well and that fan gone, that will give it another 5hp straight away!
