kit question

wanting to put alky on my car, What is the difference between a older non progressive kit and a progressive kit?

Well, the progressive progressively adds alky based on some varying (hopefully indicative of load) source such as boost, MAF, etc... Non progressive means the alky is injected in the same quantity across the entire boost range. Non progressive results in less power when you have a varying boost i.e. more pronounced with street driving because you end up injecting too much at certain points. At the track, boost is generally much more constant from launch till end.

Some progressive kits, since they are controlled with 'smarter' electronics, are much easier to tune instead of manually adjusting a hobbs under the hood. More money = more adjustability = more control = more power

The other answer is technology. The systems have seen new development making them far more reliable, easier to tune, and have negated having to subject the motors to tons of abuse "figuring" it out. This only applies to companies marketing specific kits for specific vehicles.

A look at performance on these cars using pump gas over the years should illustrate this feature. The search engine on this board goes way back.. and the progression into new style controller and performance increases are pretty clear. If your willing to dig through thousands of posts

10 second Buicks on pump gas are now everywhere. Probably would see more if it wasnt for roll bar issues, from owners not wanting a bar in their car.

This is due to better control of the injection process and an increase in volumes delivered to control detonation.
