Took a dyno before i had the work done to my car.

First dyno was with APS TT, Cosworth internals, Haltech ecu. Car made 460 at the hub with 418 torque. Car set at 1.0 bar.

Took another dyno with the same but cosworth plenum, cosworth heads and HKS cams installed. car made 542 at the hub with 494 torque. Car set at 0.9 bar.


So what a difference car made over 80 hp at the hubs and 80 torque using 0.1 bar less. Which means the plenum heads and cams conbined really help the engine to relax a bit while producing more power



I will post a video of the dyno later.

 

Nice results mate! Get this posted up on nissansportz UK forums as i know alot of people would be interested!

 

Done

 

That sounds about right

 

wow! thats a nice difference.

 

holy monkey *****....awesome!

 

wow very sick!

 

nice gains

 

very nice gains!! i will be running my stock heads with stock plenum... budget is tight!! so now i have more hp to look foward too if i get heads/plenum!!

 

Wow, nice gains...

Did you ever think about any other heads, or are you just a fan of Cosworth?

 

I kind of left it to my mechanic/tuner to decide what he thought worked best and seeing that i have cosworth internals and plenum it just made sense. I didn't go with the new cosworth cams as my tuner said cosworth designed them more for a NA application which wouldn't have been the best solution for a lower compression.

 

That makes sense.

I didn't realize Cosworth had new NA cams. I will have to check them out. Thanks for the info.
