yes, indeed, the only financially responsible thing to do !! my Jerico sheets say precisely, you must use the clutch, 200 runs later i am not going to argue, it has not broken yet,

Hey Charlie, what is the difference in ET between stick and auto in your cars? If they were the same weight. I know you know. Care to share?
How about the Ficacci crew? Any thoughts or comments? Last edited by David Barton; 02-15-2010 at 08:30 PM. |

I would say that the autos and sticks with the same motor are gonna be within .03. The 40# break makes up for the radial advantage. If the radials were consistant with a stick, than there would be a noticeable gain with the manual.

David:
This is not really fresh info, but when I was racing /BS with some good stuff, I back to backed a Glide and a 4 speed Jerico at an Orlando test day both on the same day. The auto has a 5% weight break over the stick. ie: 150# (theoretically .15 sec) They were a wash as far as ET's. Now given today's 3 speed Pro Trans (-.05) and the radials (-.04 to -.06) Doing the math gives the stick .04 to .06 advantage (theoretically) at the same weight. As an aside, I wonder why the push for a clutchless wasn't put towards a 5 speed. Think this would have been more productive. FJ |

Anybody can bolt it a Pro Trans and an ATI converter and go fast. Only a handful can put a stick in and maximize it's potential. To Charlie's point, if you can get the radial to work on the stick car, it wont even be close.

2 speed was what we had at the time. i think if we had a killer 3 speed i might have changed my mind. although, comp has a 250 lbs. break and with clutchless it seems to be a wash. i still think that is the true test, cause those guys do not mess around. but none of it matters now.

one other variable is the rpm of a small modified motor, and lack of torque. If you take a 283 SS/K car, the stick will always be faster, but as you go up in the classes, and the power and TQ increases, the gain is minimized. Thats why the stick hemis have always been lighter, the gain isnt there in a higher classed car like it is in a SS/FM car.

If you are gonna run a clutchless gearbox, 4 speed or 5 speed, you have to have a computer and a "real" clutch with the maintenance equipment to maximize the performance. If not you are gonna be left behind.
What you essentially have now is a 4 or 5 speed automatic with a lock up converter that you can set up any way you wish.... only better. A combination like this, properly set up will outrun anything in the class. Period. |
