Procharger crank support info

Bolts for ac pulley, they go thru the non-threaded holes of the damper hub:

Bolts for the mandrel and blower pulley, they thread into the damper hub:

Looks like this:

I have reversed the bolts and it didn't have any issues either.

Tweaking things here and there as the car is going through the break in process.

Well the transmission was giving me fits, but got it sorted out (after the third time working on it while it was hot AF.) Put a good run on the car to get it up through the temp. Stopped for an oil change and some beer

It's so exciting to be out on the road in the car again.

Breaking those miles in

 

[SolarFlare]

hell yea!

No miles tonight, only an oil change and the front license plate was put back on....stupid state requirements.

That’s still progress in the right direction brother! Maybe you can squeeze in some more miles soon. Perhaps a run down I-35 to the Minnesota/Iowa border and back (602 miles round trip) and you’ll be ready for the next oil change and ready for some good oil and a track outing.

Chopped down a 70 mile sprint after dinner.

120 mile trip today. Celebrated half way with a beer. So smooth that the pup got a nap in. He loved the air conditioning

Mustang is grounded due to a bad rotor hat. This must have been machined wrong from the start but just showed signs of issues. I reached out to the manufacturer to see if they can help me get a new one.

Was it causing a vibration ?

Was it causing a vibration ?

I felt it on the steering wheel. I thought it just needed an alignment since I took the steering rack out during the engine swap. Someone flagged me down on the highway to tell me to pull over. They thought the lugs were loose. When I jacked the car and spun the wheel, it was obvious how out of round it was.

Alright who knows enough about specing out converters, converter slippage, rear gearing, power delivery of a centri supercharger, etc.. to make a recommendation for me.

Car weighs ~3500
TH400 gearing 2.48/1.48/1
Rear gear 3.15
Tire diameter 27.8
1/8 mile slip earlier this year off footbrake, ~3200 rpm:

• 1.550 60'
• 6.089 660'
• 124.34 660' mph

Car would benefit from hanging around in the higher rpm for the procharger.

I think the converter slip may be way out of spec for the car or said differently, the car needs a different rear gear. Maybe 3.73 - 4.10

Anyone educated enough to pull out some facts/logic?

I called ATI and they argued that it's fine. That they specd it properly. Car is dropping 1,600 rpm per gear change which is not keeping the procharger happy.
