We had a few extra minutes today so we threw the car on the dyno for 5 runs, before Dzenno had to leave work. We are battling serious misfire and correction issues only in cylinders 1 & 4 which are usually the quiet ones :think:, even with those issues, causing ugly graphs, the car made decent numbers, and managed to break our N54 WTQ record which was 654WTQ in 5th, our previous 4th gear record was 629WTQ so we put almost 30 on it. So far we cannot seem to get the misfires squared away, all plugs look good, fuel pressure is good. I have to give my brothers car back, as I have held it hostage too long already so this is prob the last time we will put it on the dyno. We should have the shop car back up and running soon, and will continue testing. Not being able to achieve a clean pull to redline is really hurting power output, as you can see in the graph, it really wants to go from about 3800, but the misfires end the party early. For these few runs we decided to go flash only, and I told Dzenno to Wedge me, crank WGDC way up in the midrange, drop it at redline to keep boost in check, you can see he had to quickly drop it up top to keep boost at a manageable level up there. At redline the gauge was showing 22-24 psi or so, and we are just above 50 WGDC. The wedge map was showing just under 50 for a little less boost up top. Either way the car has to go back to its owner (happens to be my brother, which is why he lets me beat on it. Thanks Dave..:)), and he will try to find the misfire issues. He of course will never run the maps we dynoed on, that is as usual for our R&D, his car will be delivered back to him with a safe flash, and most likely a JB for boost control.
Full Disclosure as always.
Boost according to the gauge was about 30 psi midrange to 22-24 up top
100% E85
VTT intakes
VTT prototype CP
Shotgun Double Barrel
Fuel-it Stage 3
4th gear pull (if we did one in 5th on this map, it most likely would have made 670-675 or so.)
We look forward to getting the shop car back up and running, with a fresh motor, and testing some more! Stage 2+ with these intakes, and some serious boost should open up a few eyes...:)
