Water/Meth injection

Jordo!

For what you'll spend on the kit and methanol to mix wit hdistilled water, if it's just for track days, I'd say just fill up with 100 octane on those days.

Guys, go back and re-read my last post on W/M and also click on the link I posted -- there's a lot to learn if you want to experiemnt with it. You can't just slap it on and call it a day.

There's no replacement for octane!

Just run a slightly richer tune and higher octane fuel, and you will be just as well off as a with a complicated W/M system.

Chris, We will have to do some data logging at the track. It will be interesting now that the car will be supercharged and it fricken hot out

We've already addressed oil temps, now we need to work on the cooling system!

Yes, they are correct. Water/Meth injection really should be reserved for race applications. it is not easy to tune with this sytem and if you go to use for cooling effect only you will find youself down on power. Not worth the money.'

You already have the the oil cooler so you should be good to go. If your at the track dump ice in your inter cooler between sessions. Otherwise on the street it will opeate well with reasonable temps.

car is pretty much a track and it will eventually be a complete car, gutted and caged. Plan to boost hard so just exploring ideas I have seen to help with engine heat

Dial everything else in first. Honestly, if everything is tuned to the limit, there may be no more power to be made.

Before I had an intercooler on my supercharged 2ZZ, I picked up 15 whp with W/M direct port injection -- but I was overdriving the blower and had no IC, so I desperately needed some cooling at that point! Moroever, the ECU was pulling some timing. The W/M fixed all of that.

I had a nice coolingmist progressive controller with a W/M injector ported into each intake runner -- worked great!

However, after I had an A2W IC installed, the W/M made absolutely NO DIFFERENCE in power. We experimented for an hour with the tune on the dyno, and it just diidn't matter -- timing was optimal, and adding timing yielded no extra torque. I would have uninstalled it and sold it off a that point, but it was too much of a PITA, so I left it on as a safety measure as it wasn't hurting anything

If you were non-intercooled, I'd be more of an advocate for it. If you are intercooled, you probably won't need it.

In fact, I'd say the time and money would be better spent upgrading your IC components -- is it A2A or A2W (I recommend the latter, although the former can work well too)? If A2W, you could upgrade the pump or add another heat exchanger to further cool things down -- or as one person noted, you can get a larger reservior and pack it with ice for track days!

Also, what kind of track are we talking about? Road course, drag strip, autocross???

Does Oklahoma have access to 93 octane? What oil cooler are you using?

Since Chris is going to be doing the tuning for you, you might consider having two maps, one on pump gas for the street, and one a bit more aggressive but with 100 octane for the track...You could take advantage of the UPrev multiple map features and just change out the map when you're at the track. This is something that we've talked about but for various reasons we aren't able to offer the CARB legal, warrantied kit as an adjustable kit.

Chris@FsP

Nope, we have the same craptastic 91 that you guys do. We had 93 up until around 2006 though.

We do have a few stations that carry E85 though

Jordo!

You guys have an A2W kit, right? How efficient is the current set-up? What are post charge temps looking like?

The OP should definitely have an air-temp guage installed, ideally pre and post charge, but even just post would be incredibly informative.

Not worth it on a Z with FI unless you intend to use high boost , lots of timing, which generally the 'average' end user here will not do.
Having said that I would go with an aquamist kit if buying one.

I have asked it before but still have not seen on this forum, does anyone have any EGT data from a boosted Z?

Personally like my sig, E85 would be a better option then a meth kit for thoose wanting big boost and aggressive timing, but both have there limiting factors and pros/cons.

I hate 91 octane with a passion! It's amazing how crappy it really is.

Question for those people in Florida and other parts of the country that get 93...What is the cost of the 93 octane in your areas?

Does anyone know why CA is limited to 91?

We have found that the air to water intercooler is EXTREMELY efficient. As you can imagine dyno pulls put a lot of heat into the system and one of the quickest and simplest examples of an efficient intercooler is how long it takes for the car to cool back down after a hard pull. For example, we have been doing a lot of supercharger installs and custom tuning with the new Camaro's. Those cars are TERRIBLE on heat soak. We will do a pull, then have time to actually get out of the car, walk to the computer, get back in the car, keep on waiting...It's insane before the temperature actually comes back down. With our 370Z and G37 we can do pull after pull after pull with very little down time between runs.

Also, during our development we did insert temperature probes post blower and post intercooler (in some of the prototype/testing photos you will see the yellow wires.) We saw decreases in temperature of well over 100 degrees and at idle the IAT's were within a couple degrees of ambient if I remember correctly.

If stillen still plans to offer pulley options for more power. I know myself and will eventually get that larger horse power pulley. With all that added heat, the oklahoma heat, black car, hot tarmack. I am sure I will need to upgrade the raidator/A2W intercooler to make the heat is being handled. I plan to add a vented hood help with air flow through the engine bay. I am just trying to get a feel since I have seen it and they said they like and it works great. my car mostly drives on the track. It is not a DD and will never be one. I appreciate all your guys input and opinions on this topic. thanks
