Update 7/21/22

I confirmed the squeaking pulley is something in the serpentine belt system and not related to the timing belt. Neither the idler nor tensioner pulley feel like they have a bearing problem but I’m replacing the cheapo tensioner because that seems the more likely culprit. I installed the rear facing airbox and K&N filter. It cut the intake tubing length by about 75% but more importantly it moves the intake away from the driver’s head. I’ll wrap the lower half of the airbox with reflective foil tape but it’s at least 4″ from the center muffler so it should be … Continue reading Update 7/21/22

Update 7/17/22

The motor mount and throttle body changes were both big successes. The throttle is MUCH easier to modulate and there is almost no vibration through the new motor mounts. I might want to tweak the throttle body bell crank size but drivability is more affected by the poor idle so I need to fix that first. The clutch pedal is very light and doesn’t have much feel, so it’s still difficult to feather it at the engagement point but before I get a bigger clutch master cylinder, I need to make the car idle better because it often stalls when … Continue reading Update 7/17/22

Update 7/14/22

I suspect the reason the throttle is too sensitive and difficult to modulate at low RPMs is that the throttle body I’m using is too large. The symptom is that I have difficulty letting out the clutch from a standstill without either stalling the engine or sending the RPMs too high. When I blip the throttle in neutral only a couple millimeters of pedal travel send the engine to redline. There is a relationship between horsepower and airflow described by the following formula:Air flow (CFM) = (Horsepower × 0.625) × 1.1104 Under the best circumstances my engine will put out … Continue reading Update 7/14/22

Update 7/10/22

I put the first 10 miles on the car today. The last two months I’ve been doing lots of small things to get the car ready. First impressions up to 35 mph: Throttle response too quick off idleNot much feel in clutch point of engagementBrakes stop very well but no feel for point of engagementSteering is very heavy—two hands to turn the wheel when the car is stoppedCar tracks straight up to 35mph; Car brakes straight from 35mphIdle still a little unsteady after starting engine, but evens outRelatively supple ride with no body rollBumps didn’t seem overly harshSqueaking from front … Continue reading Update 7/10/22
