I don't understand how an adjustable guide plate is gonna quieten down mechanical valve train noise?
I don't understand how an adjustable guide plate is gonna quieten down mechanical valve train noise?With all this talk of big pressure numbers from the M112 and my goals to achieve that end, we breezed past some issues that need to be addressed. The main issue in my mind is the valve train noise, the last thing i need is to bend break or bind something while i am 100 miles from the house...
So to remedy that i bought some AFR adjustable guide plates to install today. I sure hope this fixes the noisiness it is driving me crazy! Of course i will snap some pics along the way.
I also got some plug wire terminals and boots to cut the existing wires to length, I am going to use the yellow wires i got from weapon-x.... not my first choice in color but they will have to do for now. maybe i can hide them with wire loom.... lol
Same guide plates I used on the last build, they have a ton of slop between the pushrod and the guide. Allowing the rod and rocker to move around on the valve stem. This totallyI don't understand how an adjustable guide plate is gonna quieten down mechanical valve train noise?
That's an interesting point. Complaints about roller rocker noise seem to be very common around here; maybe you have found the fix for a common problem...Same guide plates I used on the last build, they have a ton of slop between the pushrod and the guide.

High impedance circuits (100KΩ or higher) like sensors are sensitive to signal interference from radiated EMI. The fuel injectors are low impedance because it takes a fair amount of electrical energy to pulse that solenoid. Electrical interference radiated from an ignition coil doesn't pack that kind of energy to make the injector pulse or change the pulse width or characteristics.Found a problem.... I pulled the plugs and #4 is near fouled... #8 is slightly darker than the front 6. Only thing I can think of is the fact these injectors sit directly under the coil packs, I am going to create a shield on the injectors back there with tin foil. This will at least rule the coils out as interference, I am also swapping the coils and plug wires to rule out weak spark. If a new plug in that hole fouls again I will be forced to assume it's a bad/leaky injector.
The front 6 plugs look perfect, I may have to try something different... like using a plug slightly hotter in those two holes.
Nope. They were new though... maybe I should just send them out, what kind of turnaround is there on this service?Have your injectors been flow tested?
Not sure, there’s a place by me that’s good (injector dynamics I think?) and there’s another dude on FB that everyone says does great work. I’ll probably send mine out too pretty soon.Nope. They were new though... maybe I should just send them out, what kind of turnaround is there on this service?
No idea when the new pulley will be here, i have not received the invoice yet.... may need to call them again, a company like that stays pretty busy. once i have everything working i will do a few dyno runs, no meth with the bypass open, then pulls with the bypass working and meth. at 10:1 i dont want to try 13 psi with no meth or intercooler........Looks like you are moving right along. I remember doing the heater core in mine...fun...fun
Timeline on the new pulley? Dyno session?
