My instant is not instant with either the sb or the velocity booster. Actually can go into a corner and hit the gas to the floor and shout 1 - 2 -3 before it goes full up.

The idea of using a cable tb Would be interesting but I considered that and decided that since the tb is driven by a 100 microsecond pulse train of both open and close pulses, that the computer would throw a code.

One of my other ideas was to adapt the hemi 4" custom tb (1200$) but calculated that it was only 30+% bigger and no faster, so I deep sixed (pun) that idea too. I have already laid out coin on my parts store and purchased a few goodies from Ebay motors to do testing on my car next month. I have a confidence of over 95% that it will be without issue and perform well.

If I get my goal of 100% faster, (half as much delay) and more power it will be good. Since the leaning thing is over for me now that I got that working, this is the next logical step to make the car compeditive. Remember that I used to get beat all the time in tighter courses, and that I will correct, so help me Forum.

Btw if your drove the tb with Nitrogen or gunpower, the computer controls the rate that it opens and that is very precisely controlled. I had thought about adding in a log OP amp to change the curve coming out of the throttle position sensor so that the computer thought that it was going TOO SLO and try to fool it into driving it faster. THat may work but could seriously affect drivability and bring on additional complications, so it went into the dust bin as well, along with many other half baked thoughts. { cutting the tb closing spring; changing the motor; adding more voltage to the motor circuit; adding a "on spring for more go"; adding a cable to the pedal and pulling it forward: all try to fight the computer......I fought the computer and the computer won.

THis car is an engineers sand box as there are many issues to improve upon. TO date the cooling, fuel delivery and camber settings are corrected now, drivability is the focus.
