Hello everyone, looking for some help.
I have a 19 850 that was built from the ground up, everything was gone through and replaced. Has an indy specialty long rod in it the whole nine yards. at the beginning of the season we got it running and noticed the rpms were 7950 @ 645 meters but we thought the rpms would come as the motor broke in which was not the case. So i have been chasing the issues for the entire season trying to get this thing to run proper. it makes ~8050 @645m and @ 6500m. I have 66grams in it for pin weight and i have tried pulling the magnets out all the way down to 63grams with no change in rpm what so ever. The sled has been in for multiple TPS/EV relearns and nothing has changed, Had a new wiring harness put in it, and a new voltage regulator, new Tmap,New water temp, tried different ecm's, new fuel pump, the whole nine yards. It will not rev over 8100. Im being told it something electronically holding it out, but the only three things i have not replaced is the stator/trigger coils, injectors,and EV motor. Everything else is brand new. There are no engine codes, i have been through the machine like 7 times looking for signs and I, along with everyone else cannot seem to figure out what is holding this engine from revving out.
Im hoping someone on here has seen this before or knows where the culprit could be? Im at a total loss here.
Keep in mind that i cannot get it to over rev on a stand @645m with no load it should be able to rev to the moon.
Any help would be greatly appreciated
