Yes modern cars are terrible with batteries compared to those from 20+ years ago. Not only do they drain batteries, but the alternator is set up to conserve fuel rather than recharging the battery quickly. So short drives are much less effective in keeping the battery charged.

Most rust is cosmetic, but rust on the outside of the hub can make it annoying to remove the rotor if the hub gets too rusty. Part of the reason it's rusty is the bare aluminum rotor has a bit of a galvanic reaction with steel. What I usually do is use a wire brush or wire wheel on the...

When I had the GT350 with the plastic oil pan and plug, I bought a new plug, put it on the shelf and re-used the old plug. I put 30 something thousand miles on it with frequent oil changes due to track use and always used the original plug. I think the design was slightly different than the...

Believe it or not, the 944 has a back seat and it leaves more room than the S550. In Mustangs I have the front seat touching the back seat cushion and would prefer to have more legroom. The 944 offers more driver legroom than I need. But no one would want to sit behind me in either. It's...

I'll just leave this here. Edit: and one thing I should say is I'm about 6'4" and I fit easily in the 944 with a helmet on. Great ergonomics in that car for taller people. Not only is the S550 large, but you sit really high off the ground.

I see you are in Winder, GA. Jon Kaase Racing is a place I'd like to shop in. Ever have an opportunity to check it out?

I agree. There hasn't been any recent marked improvement in performance or styling of cars that are in my price range. The only reason I have to buy new is wanting to try something different. I got a letter in the mail today saying that the trade in value on my 2017 GT PP1 is $14,000. Why...

It might have just drained all the fluid out of the clutch master when the brake master had issues. That could make it more difficult to get all the air out of the system. There really shouldn't be any connection with the brakes as far as damage goes. The clutch and brakes just share a...

That's what I was suggesting. Make sure the reservoir is full, disconnect the line at the transmission and let some fluid run out. I wouldn't leave it disconnected for long. If fluid comes out quickly, reconnect quickly. You don't want to empty the master. Then reconnect, fill and see how...

Not pressure, you are supposed to apply vacuum to it. And I think you're supposed to pump the clutch pedal a bunch as well. It's been a while since I did it. If you already did that, you could try gravity bleeding. The hose end at the transmission is easy to remove. Don't step on the pedal...

DId you use the Ford recommended process for bleeding? Applying vacuum and all that?

Sorry, but if I see a car with aftermarket forced induction being sold, my assumption is there's a problem. I would need it to be very inexpensive. But yes, I think the market for cars is low right now. It's not the best time to sell.

Yes I agree based on that information that there is a small change in VE with the CMCVs open at low RPM. For all intents and purposes it is zero. For VE calculations, we would only look at the highest point on the graphs, which is WOT. The rest are not relevant to VE.

You are right that Ford says the CMCVs increase turbulence. And I'm sure they do. But the question wasn't about turbulence or MBT. It was about VE. A restriction in the intake will change VE. I agree it's a small change. But if you are measuring VE, you will see a difference if you compare...

Yes 100% correct VE changes with RPM. Old school engines have a relatively simple VE calculation because cam position is fixed, intake runner volume is fixed, and intake runner length is fixed. The Coyote is a lot more complex. The way I understand VE, you can think of the air charge within...
