The torque down low is a lot of fun. Full throttle in first gear results in some tire smoke and a sideways car. Sometimes it happens in second gear.

Here is the dyno showing Actual, not corrected horsepower, remember corrected for temperature it's 265 rwhp.

OK so the front end is grand.......gimee, gimee, gimee, but how long will the gearbox and diff last with the kind of abuse that that lead foot of yours gives?

man thats excellent power for 7.5 psi.

Great job Greg - that is more than a mild, but fresh 24 valve 3.2 running 10.7:1...

Just awesome for "bolt on"...!

What size is the water/meth tank - How long do you run around with it? How do you know when it is empty? Is there any protection for the motor when you do run out while under throttle...?

[Greg Gordon]

Thanks Patzo! We are getting a lot of power per pound of boost.

JJ: I guess it is technically a bolt on. I think it has a little more than a 3.2 at the high end and a lot more at low and mid range rpm. I don't see these two things as comparable because they are not mutually exclusive. One can bolt to the other. If only someone would come up with a way to make the driveline handle a 3.2 24valve with forced induction!

Quite a few water injection questions. Here are the answers.
1. The tank is 1.5 gallons
2. It will provide enough water for A). about 2 tanks of fuel in normal street driving. B). About 1 tank of fuel in agressive street driving. C.) about 30 minutes at the race track, probably more.
3. We know when it's empty because the big red "empty light" comes on. There are also two secondary indications in the event the system fails for any reason including running dry.
4. There is massive protection for the motor when it runs out. This car is pretty mild so the water meth is extra protection not the first line of defence. In other words with a total failure of the water injection system in most cases the car will be fine. I think the motor could survive a total loss of either the intercooler or the water injeciton in almost all conditions.

Suppose the water inj. sys. does fail. The driver will know it and can avoid using full throttle. Even if he does use full throttle as long as the supercharger's discharge air temps are low enough there is no danger. There is a temp gauge in the car for this reason.

In short, the danger of a failed water inj. sys. is trivial compared to the danger of a clogged fuel injector, engine management problem, or blocked intercooler neither of which will give you a warning sign in most cars.

Greg,

The A/F is very stable! I think an aftermarket EFI should be high on the list when boost is added.

[Greg Gordon]

This EFI system is really nice. I just can't say enough good things about it. Good old L-Jet does work pretty well though, at least up to 10psi. It all comes down to the user's choices and budget.
