Well I read this entire thread yesterday,all 1200 posts!
I noticed no one is running this engine in an oval car.
Im running an Ofna ULTRA GTP DIRT OVAL Late model on a dirt track in So Florida. I broke in the engine like the manual suggested and have about 5 race weekends on it so far ( a little more than 1/2 gallon).
Its runs incredibly strong and I have actually posted the fastest lap time of the day twice with it. After reading the thread i get that in different conditions it may run what some would consider hot. Though I have been racing for some time, this is my first Nitro car so I can only go by what I hear or read.
Im running a 97t with Oddonel 30% and the stock pipe that came with the Ofna kit. The track I run at is a loose clay oval with a 250ft runline.
Since we are running oval i am running full throttle most of the time and the engine seems to run best around 280-290 deg after a 4 min race. last weekend however i came off at 325 and toward the end of the race i came out of turn 2 and lost all power.Power came back by the middle of the back straight. I managed to finish the last two laps by taking it easy and it was idling high.The LM body has a 3 in hole in the windshield right in front of the cooling head but i dont know if i need to make it bigger or maybe cut an exit hole in the back window to let some heat out.
I have smoke all the time and it very responsive.
What can I do to help bring down the temp?
What is too hot ? I dont want to hurt the engine but I really like how it runs at 280-290.
All the other drivers think Im crazy running it that hot since they are running mostly Vspecs and come off around 210-225.
Any advice would be greatly appreciated.
