Timing and EGT ?s
When finding the inner base circle which was do you turn the engine? This article, http://dodgeram.info/tsb/1994/18-10-94a.htm, says counterclockwise from front of engine. Is this standing in front of the engine looking back? Or is it from a drivers perspective looking at the front of the truck?
Reason I ask is that if I turn it CCW while standing in front of the truck the dial indicator rises instead of dropping off as it says. Also I get a reading of 7-8mm this way and I know my truck cant be timed that far.
If turning clockwise from standing in front of the engine until I find the inner base circle and proceeding with the instructions I come up with 4.85mm give or take .05mm which is right about where I set it initially.
Background. 215s, #10 plate almost full forward, 3K GSK, AFE filter on stock tube and Dodgezilla turbo set at 42 PSI (factory settings from my understanding). With this setup I could hit between 1100-1200* WOT. I could pull local hills (MD and PA) at 70-75 MPH and maintain or pick up speed without going over 1300* as long as I didnt bury the pedal.
Picked up some Bosch 90HP sticks and swapped them out for the 215s and I could hit 1400* and rising before 65 MPH on a WOT run. Couldnt keep the EGTs in check. My guess was I should be in the 375 HP range with the 90HP sticks. I dyno'd the above set but with the stock charger last fall for 315/799.
I have since dropped back to the stock 180 injectors and I am still having EGT issues. I can get hotter now than I was with the 215s and I am down on power. I figure slipped timing plays into it but after tonight I am not so sure unless I am checking it wrong.
Sorry for the long winded post but I am starting to get frustrated with this truck. I go from a nice running truck to one that I cant keep the EGTs in check even with smaller injectors and less HP.
Any one have any thoughts or suggestions? Lift pump is new in the last couple months, overflow valve is also. Not sure what my fuel pressure is, havent hooked up a gauge yet. Fuel filter is also new in the last few months. Timing looks to be at 15.5* give or take maybe .5* unless I am wrong on how I am checking it. Using the Miller/SPX timing kit.
