Re: Smoother shifts at maximum torque rpm: why?

Lots of possibilities, nothing definite. several things are tradeoffs and that's the balance point I'm guessing. along with a bit of timing thrown in for good measure. factors include: -time it takes the main and layshafts to accelerate/decelerate. -time to slip the synchros, engagement characterist...

Re: Snow/Ice and Stalling

Keep in mind when you're stuck, you aren't going to get moving if the tires are spinning. If the clutch is out and you aren't moving, the tires ARE spinning (or something's broken). It sounds like you're trying to get moving when stuck by modulating the gas pedal with your foot off the clutch. If th...

Re: Is it possible to mistake a near-stall for lugging?

Actually, it's probably a combination of low revs and wheel hop. There's a little slop in the drivetrain no matter how good a car. Just how it is. at high speed, there's enough torque to keep the wheels spinning continuously but at low speed the release of tension when traction is broken lets the ti...

Re: Being agressive with the clutch

At the physics level, the rpm drop is caused by torque is being transmitted to the wheels therefore; all other things being equal, more RPM drop = more torque at the wheels. As to whether transferring 5% of torque available at 1500rpm vs 50% of torque at 1000rpm, that somewhat depends on the engine,...

Auto-cross video

It's to quiet here, lets add some music. https://www.youtube.com/watch?v=VAj0oNL0yYU 1994 Firebird LT1 6 speed. colder t-stat, true duals w/ H-pipe, SLP-tuned Bilstein shocks. Since then I added WS6 springs. Needs better tires and a cornering-friendly alignment. And, you know, not to be an F-body go...

Re: New manuals...

Random bits and pieces from reading the replies: I know entirely too much about vehicle/engine development. I work with #$%^ing engineers all day on engines. It's depressing to think about. Just numbers on the computer screen The problem I have is not the amplitude but the speed of response. Those s...

New manuals...

Rant against new cars AKA the real reason stick shift isn't popular. it's not because it's hard, it's because newer vehicles are harder to drive like an expert. I've been driving stick for close to a decade now, most of my vehicles have been that way, exclusively for roughly the last 5 or 6 years. m...

Re: Slipping time when getting going in first gear

What he said, at that low RPM you aren't doing much damage. That's prtty much my normal driving style: let the clutch out at idle and start feeding it gas as I cross the friction point. 2-3 second is probably a bit long but as you say, you're just learning: as you get more practice you'll notice you...

Re: clutch wear during upshift

A lot of these questions will become moot in time as the action of shifting becomes muscle memory. Just do what makes the shift feel smooth and right. A lot of the answers depend on your timing and the vehicle characteristics. For advanced drivers experienced with a particular car that can shift qui...

Re: Post your oil changes here

Most of my vehicles get the oil changed once a year (checked a bit ago, 2500 miles combined between the bike, truck, and firebird) except the wifes mazda which might get it twice a year (10500 last year but 90% highway). It's going up though since I now live 8 miles from work instead of 1. I use mob...

Re: windshield washer fluid pump

Sure they wear out. everything wears out eventually. they don't wear out often though. If you can hear it, it's probably fine but either it's iced up somewhere or a hose fell off and it's just peeing on the ground. There's a small chance the pump itself is bad while the motor's OK in which case you'...

Re: clutch disc thickness question

Short answer: not difinitively. I know 2 ways: 1: old clutch vs new clutch thickness is less than that of a dime. Old clutch defined as the vehicle not being able to get over 60 mph due to clutch slippage. new one still has paint. 2: .020" step on the flywheel is the difference between my car not ge...
