What kind of Alfa?

I learned how to drive stick on a GTV (God bless my father). My first car was a Guilia Spyder.

Synchros were delivered gone I think.

Mike,

I have a '77 Spider Veloce. Love it, but am now thinking of selling it because I'm driving the you-know-what more than I thought I would and now it's sitting more than I thought it would.

I tracked the car often (DEs) and put a whole lot of road miles on it...loved every second! And the sound of the DOHC through the Anza twin tips with the top down and the dual Webers roaring...whoa, really intoxicating! But I guess I can't complain too much, considering what I've got now. BTW, those GTVs are still cool to have. You still got it?

I think double clutching is a huge pain in the *** and I don't do it!!! not even in a car with no syncro's. I have found that a monster blip is suffice. I have never ground a gear.

I guess given the time and the effort I could learn to double clutch properly but hey..
That would make my track driving even harder..

I mean, just imagine...
Double Clutch Heel n toe downshifting while threshold trail braking into some trailing throttle oversteer while looking ahead and adjusting steering and throttle input that's a lot of work...

And since there is no need to double clutch modern cars, it's a thing of the past. I think it's actually more important to know why you should double clutch than it is to actually do it.

and btw, Danny Sullivan has been quoted as saying he has never double clutched a day in his life. He just monster blips...

good luck

It was a '67. Long gone, after three teenage boys managed to trash it on my Dad.

I know the sound you're talking about. I used to take the air cleaner off just to hear those Webers gulp air in 2nd.

That's when the GTAs led by Horst Kweck used to regularly whoop the 911s in Trans-Am
U2L.

I've often thought a GTA would be fun for Vintage racing.

I am also an expert at double clutching (meaning I also had an Alfa. Guilietta Spyder). Alfa synchros worked perfectly, as delivered, and for the next 200 miles.

Zum,

A heel n Toe downshift is one of the most important things you can learn to become a smooth, consistent, high performance driver.
Aside from looking ahead and threshold braking, it's something you really should learn.

WHat heel n toe downshifting means is: Using your right foot to simultaineously brake and blip the throttle at the same time. Your not actually using your heel and toe, rather your using the inside and the outside of your foot to press both pedals at the same time. Thing of hitting the brakes really hard, while you are doing so, use your knee to throw your foot to the gas pedal. Your outside of the foot should "blip" the accelerator to get the revs up.

The reason this is important is, lets say your going into a turn. Before every turn you should be braking which normally requires a downshift. You can brake and downshift at the same time. But if you brake and just release the clutch, you have not matched engine RPM's and the car will JERK or UNSETTLE. But, if while you are braking, you blip the throttle (while the clutch is engaged) by the time you unengage the clutch, the rpm's should be matched to where they were in the previous gear. Or if you dump shift, you need to blip the throttle appropiately to match the amount of gears you drop.

A dump shift is if you go from 4th gear to 2nd gear and skip 3rd. Or from 5th to 3rd, or 5th to 2nd etc.

You can learn to heel n toe blip downshift in a secluded street. I don't suggest trying to learn it on a track. Remember though, you have to be carrying some speed. When i first tried to learn I did it at slow speeds and that doesn't work. You need probably about 40-50 mph.. One of the reasons for this is, the brake and the accelerator are at different heights. The Accelerator is lower. So, if your not depressing the brake hard, you probably will not be able to blip because of the height differences.

Hope this helps..

that's because he's not driving his OWN car!

I do agree though you don't need to d/c a street P-car.
