    2005 Wiper arm - change?

    I'm taking a slightly different approach. I bought a spare set of Viper wiper arms and a set for something else with the common shepperd's hook blade attachment. Going to cut and weld.

    So I decided to check my compression and here is what I got..........

    Those results look fine, well within 10% Viper cylinders are numbered correctly (unlike Fords) front to back. Since the left bank is farther forward, cylinder 1 and all other odd cylinders are on the left side.

    Exhaust Sounds Different On Each Side

    Exhaust leaks work both ways, depending on where it's at in the firing order and RPM, it will allow exhaust to escape as well as pull air in.

    another Transmission noise thread.

    A lower brake pedal is an indicator of a bad wheel bearing also. A slightly wobbling rotor will push the pads away from the disc.

    another Transmission noise thread.

    Transmission noise usually drops considerably in 4th gear since it's 1:1 and the gears aren't loaded. Yours sound like it could be a wheel bearing.

    FINAL answer on Gen V Viper Differential lubricant...plus a Gen IV tip...

    Selecting manual trans lubricant is kind of a balancing act. One that protects the bearings and gears, inhibits the function of the syncos, and vice versa. One that allows the syncro to grip the gear doesn't protect the gears as well. I've pulled apart dozens of Chryslers old 4-speed, the...

    Gen 3 vs 4 blocks and cranks

    This is definitely a confidence builder when grinding.

    05 rods not fit 03 block

    It's common practice (non-Viper) to clearance the block with a die grinder when installing a stroker crank. Is it possible to do the same here?

    Clutch or something else??

    Couple of things. LTFTs get updated in just a few miles, has to be in closed loop with the engine at operating temp. LTFT is not just one number, it's a matrix, MAP vs RPM. Here's a snapshot using HP tuners logger:

    Clutch or something else??

    From Chrysler tech training manual (the complete manual is too large to attach).

    Clutch or something else??

    Since it's the same on both banks, it's unlikely to be a plug, wire or injector. Clogged air filters, restricted exhaust (CATs) or MAP sensor could make it go rich and be the culprit.

    Need input for hi flo cats

    This is the standard test every shop uses to check CATs, normal should be ~200F before, ~400F after, checked with an IR thermometer. Much easier on a non-Viper with everything exposed.

    Gen 2 overheating in Texas sun… go figure

    A 160 thermostat starts to open at 160 and will be fully open by 170. A 180 thermostat will be fully open by 190. So, at 200, both thermostats are fully open and do not provide any restriction, they are the same. At this point the cooling is determined by the rest of the system.

    Clutch or something else??

    A couple of things. If you unplug a plug wire at the plug, you should get CEL almost immediately. If there is a plug that is not firing (shorted, fouled etc) the upstream O2 sensor will detect the excess unburned oxygen from that cylinder, the engine controller will interpret this as...

    Clutch or something else??

    The "rotten egg" smell is the classic complaint with catalytic converters. Been that way since the 70s, always hated it. It's normal, whenever I witness a Toyota (or anything else) go wide open in front of me, I get a whiff. But, your metal exhaust tips or pipe is actually expanding?
