I have to make sense of the dyno charts so I'll post em up this weekend, but the numbers were - 271hp and 280tq
I can tell you that this thing is wierd to dyno. Originally we got the tach signal from one of the coil signal wires, but for some reason the calibration was off and it didn't record the correct rpm so we then chose the optical pickup off the rear tire, but as we found out the torque converter locks - but it doesn't stay locked through the pull which I think ir reducing the power to the ground capability.
Also, when the power valve opens, the engine actually looses power instantaneously then picks it back up which you'll see in the graph. I wanted to try and run it with it off for the whole run, and again with it on the whole time but I ran out of time since it was a non scheduled dyno.
Also, the Air / Fuel ratio was wierd as well. for some runs it was pig rich down to 11:1 and some runs it was up to 13:1 - again need to make sense of the graphs before I can have an idea why.
Also, 3rd gear will carry to 6900rpm but 4th gear stops at 6600rpm, I think that it was possible the speed limiter was kicking in, but again, need to check the graphs to be sure.
All in all it was fun. all I wanted to do was make more than 250rwhp and I did, definitely didn't loose power like most would have thought. I guess you can mod these cars, just have to do it correctly.
I expect at least 7-10hp with the cutouts open and when it finally gets tuned - possibly another 10hp +
good times!
ps: the weopon R intak looks to be the closest representation to my homade intake, I'll do some more research to figure that one out, but I definitely wouldn't use their filter media - swap it out for an AFE oiless or amsoil nano oiless filter
