Why does the JRSC make more power with 93 octane gas rather than 91? If it's because the ecu is retarding the spark due to knock, would water/meth injection help? Anyone tried this?

I think water/meth injection was brought up before, probably buried under the college class about physics, but, if I remember correctly, it was determined that it would be much more work and trouble for what its worth, unless you are going for a serious track and track only car.

No analogies?
I'm disappointed.

Yes, I tried to read the physics stuff, but it gave me a headache. Can't believe I made it through 95 pages. I just remember one post about it sucking air on hard turns & having to constantly top it off to make sure it doesn't, then grenading an engine if it ever ran dry or if you forgot to fill it. Not sure the idea has been fully vetted out, though, since there are a lot of very advanced, failsafe WI systems available now (Snow performance, aquamist to name a couple). Seems to me like an idea worth exploring if for nothing else than the extra insurance against detonation & the steam-cleaning effect on the pistons. It's like, if you dropped a ball off of the empire state building, the vertical wind shear picked it up and it hit a plane going 500 mph over London, it would take 85 seconds before the kid in seat 35B would start crying about the dead bird falling over France at 35 feet per second, which would accelerate the flux capacitance of the ionosphere 22 percent per coulomb, which is why you'd get orange instead of green northern lights in January during a rain shower in Alaska...

Dammit, I had to look up what you were talking about lol. Figured it was about sound frequency lol.

Because 93 octane allows for more timing before knocking.

Yes, water/meth injection would help, but it adds another failure point to the car. If you even have to ask about it, I would not recommend it for you.

So, do I understand correctly - even though CARB tune was designed for 91, using 93 would actually be better?

I'm just thinking if it would make sense at all to use 94 available at Chevron in our area. Will it give more power? Any other pros/cons?

I don't understand. You don't recommend adding water injection to the JRSC kit, unless I can do so without asking someone about it first?

I think what he means is, if you do not have the know how to judge for yourself if you should get water/meth injection, then you are not ready to do it. If you have not already planned out potential failures/potential problems and what it means to run it, then it might not be recommended.

That's what I got from his post.

[Coheed]

Water injection is a great way to add power, but the complexity of the system, and reliance without a proper fail-safe is a potential point of failure. One which could be catastrophic. A well thought out system can be very reliable and easily maintained, much like any fuel injection system. As with any modification, there is a risk to accompany the benefit.

Completed my first weekend on e85 on the track at MSR Houston. The car ran much cooler and made good power. I was not afraid of detonation at all. The power was smooth and kept on pulling when I was on it. Above is the picture of my dyno on e85 with remote tuning by moto-east. Blue is the after-tune red is the baseline pre-tune. All weekend I was battling with a race-car corvette ZR1 and all other cars I just passed up effortlessly. All of the bigger horsepower cars kept on thinking they could leave me in the straights and they all were surprised I stayed on their bumper.
