I was assuming that with an electronic boost controller, you would always run the Methanol. Then, if it ran out or you weren't using it, it would switch back to a lower boost setting (say 6psi with no meth or 10psi with meth)?.?.?

I'm curious as to why you don't run it all the time considering it's pretty cheap and adds a bunch of power?

Another question: does the meth get used up much if you're not boosting much?

The plain kit uses a cheap pressure switch that didnt work at all for me. I had to buy the controller just to get it to work. The alkycontrol kit is near the same price and uses braided steel line (so no leaks like I had at EVERY fitting) and a better pump.

You set the meth/ alky to come on a predetermined boost setting. If you dont hit that amount of boost, it doesnt spray.

If it where me and I could run 8 psi without KR I would set the alky to come on at 6 psi that way it has alittle lead time to catch up.

So it looks like Alky Control is going to be the one to get.

Is there something wrong with the kit STS supplies?

It sounds like no one has tried it. Unless its one already mentioned.

Nothing wrong with it. Just cost more than the alky control. Just trying to save a few pennies so i can put it on some other mod.

On the dyno, I saw a difference without any changes to timing. Look here for some dyno graphs:

Exactly.....

The GN guys really don't add more timing they add more boost instead. They can effectively go from 18-20psi without meth to 24+psi with meth but the timing stays the same in most cases.

Remember that more timing doesn't always equal more HP. Timing is just like it's name, it is timing the valvetrain events and once you pass the point of effieciency with a particular combo adding additional timing doesn't help.At least that's who I've always known it to be.

The STS kit doesn't have the adjustableness of the AlkyControl kit and it's awesome progressive controller. It's a big pain in the *** to wire up but it's a very cool kit. I lik the fact I can easily dial in more meth at the touch of a dash mounted ****. Makes for a more secure feeling on the street if I notice even a tad bit of detonation.
