i dynoed my partial bridge port with the 60-1
 
well i live in albuquerque NM which is 4,946ft up here and i dynoed at 269.0hp and 209.7torque, and at sea level it has 336.0hp and 254.4torque. now rember that i have the stock intercooler and the stock mass air flow sensor, with the 60-1 with a .81AR, and only 10 psi and it went down to 7psi when the run was done. now another thing to rember is that i built this motor and made the turbo manifold , and im only 19 years old so this is the first motor i have built and ported. i will have pics with in the day, thanx

How are you running a BP w/ the stock ECU?

Crusader_9x 05-23-02 09:22 AM

hey you have what i want. i was wondering if you could elaborate on our setup, how long you have been driving it, is it street? all the normal questions cuz i want to do this to my car eventualy. so what did you use to do the prting? where did you learn or what did you use? thanx

rotorracing 05-24-02 02:20 AM

well the only thing bad about the stock ecu is i cant do the timing, but for fuel i have a HKS aic, and apexi safc, so i have the fuel but no timing and when i dynoed i did not do the timing all i did was the fuel. when the pics come up u will see that the hp went up, all the way to 8rpm and wanted to keep going {keep in mind that i lost boost, it went to 7psi by the end of the run...} but the b port has power to the red line and good power. as for the street driving its so nice i like it but for the people that dont like 12 mpg than the p bport is not for them.

Your engine must be choking with a .81 a/r which most likely why your boost drops to 7psi.

Yeah, .81 sounds a little small for a bridgeport.

relvinnian 05-24-02 01:38 PM

I'm not sure what the stock ECU runs for timing, but I would not be surprised if you blew your motor due to this. The intake opens much sooner, and you have to adjust timing to account for this.

And yes, a .81 A/R is small!

Anyways, good luck with everything.

Crusader_9x 05-24-02 05:04 PM

cool glad to hear. yeah i always thought that you could go witha divided 1.00 minimun on a stock motor and even bigger for a bport. anywho i onlly get 214 mpg at the moment so i wont be mising much

rotorracing 05-24-02 05:48 PM

well the thing is i have a stock mass air flow sencer on the car,, and the inlet on the turbo is 4 in and the inlet on the stock mass air is only 2 in,,, so and the stock intercooler is a bad thing to bec it sets on the motor just getting hoter and hoter. i am saving for a AEM but u know how that is!

Yeah, that air flow meter is a definite retristion. Once you go with a standalone system you can get rid of it. You're still using a stock IC? You're brave.:eek:

How the hell are you guys seeing those dyno pics?&nbsp All I get is "Image Pending Approval" "pics". :(

Theoretically the stock I/C will cool ok compared to a steet-ported engine making the same power because he's running low boost.
