The bottle would have to go in the boot. Underbonnet temps would heat the bottle to much and possibly make the relief valve pop.

Along with a CO2 spray onto the IC they also have a block to run liquid CO2 and fuel to chill the fuel. From there the CO2 would travel to the IC. There is also a sleve to place in the Air intake hose to chill the incoming air.

I wondor how this would work for track use but I'd imagine it's more of a 1/4 mile type setup. I'll have to ring them up and ask.

 

A timing light will still work on these cars you just have to supply your own marks. I use this set up on the dyno often. Even though the Mini changes timing on a cylinder by cylinder basis, you can still get a real good idea of what's happening. The other method that I use that's very reliable is to install a piggy back computer that data logs as well. You'll get live info on any parameters that you choose to view. The advantages of the piggy back are obvious in that you can record anything from a 1/4 mile blast to a 30 min rack session. Knock is also a good parameter to monitor.

 

Latte...I am using the Varicool controller but have not used the MAP tap yet as I'm not sure which cables to splice into...my controller is connected to the DFIC via a one foot tube...my bottle is a 7qt Snowperformance bolted to a 1/4"MDF in the boot...

DEI sells just such a kit but I'm not comfortable with carrying around a 25lb bottle of CO2 just for cooling...I feel the WI does a much better job of cooling AIT...during boost, I can see the AIT drop below ambient...

My OBD/Palm can read timing advance realtime (no data logging that I'm aware of)...what kind of degrees should I be looking for under WOT John?

 

Sid, The Auterra software will preform logging I think if I read the horrible manual that comes with it right. Not sure what you are using on the palm.

Next week I think I'll have a much better ability to capture logging data. We are installing the G2X finally with gauges and probes for all kinds of stuff. Now it's be just a matter of sitting down with the coupla hundred page manual and figuring it all out.

 

I'm looking into the manual too

 

Never noticed this nice little feature...:impatient

I just installed a "Snow performance " Kit. located the injector in the air horn after the i/c. The tanks and pump are in the rear boot, and the liquid line is under the side trim and seat... I did get the Vari-boost selector ( which I mounted in the eng. compt) , and the anti-siphon solenoid !!

Because the pump is adjustable and the injection has the min/max boost engagement.. I will tune the system ( not the ECU) on the dyno to see where I need to be... But man is there a diff in the 90-100 Heat here in Fl.

Just me......................................

pls. keep us posted . i'm getting a progressive from snows and would very much like to hear where and how much you've got the juice coming in .

 

Rocking...Tony of "HP Performance" is in Europe Tuning Ford GT's and I will wait for him to return to Dyno... probably next week, I hope! Wanna see some stupid?? go to www.turbofordgt.com , if you havent seen this... it is unreal!! click on the 21 minute movie!! and Hang on!! Welcome to the streets of Jacksonville Fl....LOL

you know ... i usually won't sit and watch a long vid. like that ; but it was very interesting . i almost puked when it was on the 1/4 ml. and lost bite . i've seen guys on a small oval waste their brand new cars on the last turn in grudge matches . it's heart breaking . that is one beautiful car .

 

i have had experience with devilsown methanol injection and i have nothin but great things to say about the system, and its not overly pricey, im sure we could even get a GP going for it to get the price down. By the way that is a beautiful tank' controller setup

 

this coolingmist kit is so pretty and user friendly (easy) compared to the snows , i just might have to go with it instead . it is a big bottle though . but.... wicked nice lookin' .

 

On wednesday we installed the boost cooler stage 2 from snow.
First run with just plain water and the 100ml nozzle, at 20°C outside air temp and full acceleration at 7000rpm in 5. gear, without water 60°C inlet temp and with water steady 44°C .

 

nice!!!

 

Curious...where are you taking your reading from? My reading always drops nearly 10 degrees below ambient during injection...

 

Thumper, does Tony have any ECU tuning options available for the MINI? That video was incredible - I was even more impressed after finding that from the factory, the Ford GT turns only out a measly 550hp and 500ft/lb.

 

Tony does.. the unichip he can tweek to what ever you need... I am not going to worry about the ECU till I finish " working it" on a stock ECU!!
Yeah.. He can make power from a rock!! LOL as a matter of Fact... He just came back from Europe, where he was tuning the GT's over seas.. cool??

But ...yes He can!!

I'd like to go back to a flashed ECU. With the Unichip, I was impressed with the initial results. Performance continued to improve after driving around for a couple weeks. Then, about 3K miles after the tune, the ECU seems to have learned its way around the Unichip, and I'm getting the occasional CEL. I'm sure Tony can do wonders with the Unichip, but it's the practical limitations of a piggyback unit that leaves me somewhat underwhelmed.

Back to WI/AI - it seems like for a trunk-mounted progressive unit with SS lines from Coolingmist, it would come out to ~$600-700 for the initial sunken costs. That doesn't include the cost of methanol over time, but it should replace the 1/2 bottle of Lucas Octane Booster I'm currently adding with every tank of gas. (It's amazing how the ECU will adapt to higher octane - now and then, I won't add any octane booster, and when the tank is half empty, you immediately notice that the throttle response isn't as crisp as crisp and the car feels sluggish off the line.) I'm wondering if it isn't more cost-effective to deal with pinging by simply going with a head that removes hotspots (at least, RMW head users have reported resolution of pinging after install) instead of trying to increase octane rating of the 91-octane through AI.

 

I was looking to increase power on a street driven ( hard street driven) MCS in 100* road heat and not too much air flow over the I/C. The w/m is great for that... no mater how hot it is outside , or how less the flow over the I/C, this seemed the way ...... 500.00 for the Snow injection/ variable boost/syphion solenoid vs the 800.00 for a trick I/C. Also as you are seeing..cost can be ..water?? windshield washer fluid..? Meth/ water mix?? and it is on only when you need it! Sit in traffic, build a lot of heat in the engine, get a straight streach and nail it!! The engine thinks is is 50* out side and pulls HARD!! Befor the "air can even start to cool the i/c" !! Works for Me.

We read the OBD output,
just for confirmation this was with plain water no alcohol
and the 100 ml/min nozzle.

 

I see...50% methanol makes a big difference in my case...my readings yesterday, ambient 84F, 5gal/hr (315ml/min) nozzle at 130psi, AIT=74F, 10F below ambient...

AIT from OBD, ambient temp from OBC...

 

I was cleaning the garage yesterday and miraculously found a canister of 100-octane fuel that still had about two gallons remaining. I dumped it the MINI, and had a blast - the throttle response was amazing, and it just wants to pull! For those times when I restrained myself, the throttle response was perfect even when there was only vacuum and no boost. That got me wondering, though - since the AI comes on only during boost, does the MINI ECU adapt and also help optimize throttle response (like with higher octane petrol) even during vacuum?

10F below ambient sounds like it would make the car feel crisp all the live long day, but do you need to be on boost (with the AI on) the entire time?

 

Anytime you get moving, you're almost always in boost to some degree...with a progressive controller, it ramps the injection from 1psi to what ever you set as WOT...in my case, at 13psi...anything above that is using 100% duty cycle of the WAI...

 

Thanks to everyone for the all the input! I ordered a trunkmount kit with the Varicool progressive controller from Coolingmist - the proprietor, David, was very knowledgeable (he's familiar with some of the NAM members who ordered from Coolingmist). I also obtained 20ft of stainless steel Teflon hosing and the flow/clog detector, and will be doing the install on the weekend of Jun 30th - I won't be tapping the IC exit horn myself, so I'll be making an appointment for that sometime in mid-July.

Also found a good source of methanol in the Bay Area. Priced at $3.25 per gallon, and you can bring your own container (min. 5 gallon). They also offer various racing fuels (for off-road use only, of course! ).
