ok, I need help. currently I am about 3 to 5 seconds off the pace in my local club events. I know most of the time is due to the driver. I think that there is some time in the car also as it is mostly set up for the long track.
Here is what I know so far, if more info is needed..ask... 73 914, blue. bolt in cage, just the 4 plates plus the seat belt for tie in points. stiffly sprung, Koni yellows, I think 250 lbs in the rear and 21 or 23mm torsion bars in the front. Delrin bushings everywhere, I have needle bearings, just not installed. lowered, see pictures for height. 4 inches in the rear to the bottom of the engine mount bar, 4 inches in front to the bottom of the front floor pan. 205 50 15 tires, not sure of the wheel width, 4 lug. my tires are about 8 year old khumo v710's that have been in the garage and have 4 autocross days on them now. air pressure I have been running, 22lbs front, 20 rear. see pictures for chalk. looks like I am using all the tread. Camber is close to -2.4 degrees front and rear. Front toe is 0, not sure about the rear, perhaps 1/4 inch toe in. Motor is 103 by 80, nickies, split cam, le200 heads, tangerine header, 6800 rpm redline, 11:1 compression, so plenty of grunt. Megasquirt with twin throttle bodies. Transmission is open diff, with a flipped 5th gear for 3rd and standard 5th. no camber plates, See pictures in the following posts.. |

Looks much better. There are places you will NEED to coast a bit. Don't let that bother you. In some places it is the faster way around. When you learn better throttle control you will be on throttle in the coasting spots but slowly, and controlled. I would say the loose rear is too high of tire pressure. I suggest going lower before going back to the higher pressures. In my opinion, your pressures are 5 pounds too high.
Do you have the ability to lower the rear ride height? |
