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

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

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.

13BAce

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

relvinnian

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

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

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!

13BAce

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.

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

peejay

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

HWO

i get that **** too.....

oppressor666

Albuquerque Huh, I live there, whats your Rex look like maybe I have seen you before. i didn't think there were too many ppl who like rotarys in ALB.

rotorracing

ya the pics are still PENDING APPROVAL , if u look at see all pics by rotorracing then u can see my car, and turbo,

is your engine full bport or half? did you take pictures of your ports?

rotorracing

it is a 1/2 b port and i have pics of the porting, it will take a day or 2 bec i have to put them on the net
