I am running a 74 914 with a 901 trans with a quaiffe. Running in Blue and really wanted to go to white so I was really pushing and showing that I could be agressive. Running at Summit point, WV which is probably the same as most tracks. Long Straight followed by a 180 degree turn.
Going down the straight in 5th gear, shift light comes on so I am close to redline, full throttle, 500 feet sign, 400 feet sign, 300 feet sign - off throttle - full brakes, 200 feet sign, 100 ft sign, clutch in - Shift from 5th to 3rd with a throttle blip and turn in going about 50 mph. My problem is sometimes I rake the gear. I read in an article that you should pause in the middle of the shift to smooth it out. I think my eyes were wide open and I was trying to hurry the shift because I was taking the turn fast - MY instructor even said that was hotter than I take it but your car really holds. One time he even yelled that I was spinning but it was just trail braking and I throttled out of it. At the end of the session he did say I was ready for white - will probably get moved up next event. Is there a good way to learn to shift smooth?? - I dont want to screw up my ride. |

Don't mean to be argumentative (it's just not my style!) but I have no trouble skipping gears on my race car. Going into turn 7 at Road Atlanta I drop straight from 4th to 2nd,and going into 10a I drop straight from 5th to 3rd. Going into 10a I can actually brake much more effeciently by not dealing with the extra downshift. Going into 7 there just isn't time to go through 2 gears without getting out of the throttle a bit sooner.
The big breakthrough for my car was to hook the Rennshift to the JWest linkage with a fresh rebuilt tranny with all new synchros and sliders. It helped tremendously too that I gated the neutral travel at the shifter. That makes every shift identical and much more precise. Since I did all of the above prior to this season I haven't missed a single shift, or grabbed the wrong gear. Swepco gear lube too. |
