you must really be bored at work. you should thank the IT guys for not monitoring your web browsing

 

Thanks Jan

 

Actually your right, one day I'll get in trouble Back to work

 

yore!

 

Not all pumps are the same, with some pumps if you use straight meth you are going to reduce the life of the pump - make sure it can handle 100% methanol. Some companies advertise the use of WATER/METH mix due to potential issues with the valve inside the pump. It is important that the valve can tolerate a steady diet alcohol, while providing sustained high pressures.
But the higher the % of meth the more power particularly when you tune for it...

Also I forgot to add in my experience if you are running a 50/50 mix you need a smaller jet than running straight meth to get the most out of the system....but there are heaps of variables, pump type, flow, jet size, your engine and most importantly the tune.

The advantage of the RMW kit is that it will be tailor made for the mini and you won't (hopefully) have to play around with the system to get the optimal balance.

 

Thanks for the info D-MAN. Knowing Jan and how he works all the variables are being covered. I know this system will work different than previous systems from talking with Jan. His idea will work great for me with track use and regular driving.

 

There are many options on the mix. I've had friends run 50/50 and blow the motor on a cold morning. One hydro locked the motor as well.

We tired 50/50 1st on my hotrod and didn't gain anything. No timing could be added. We switched to 100% and picked up 40HP after the tune.

Remember water doesn't compress and doesn't burn.

The kit I use is from Alkycontrol and he highly recommends 100% with a kit that supports it.

I look forward to the RMW kit.

 

There is more to tuning for meth than the mix - you have to take into account a whole range of variables.

In my experience with meth kits what works on other cars does not necessarily work on minis.

I have been playing around with my kit for several months and we are still trying to find the optimal balance. I am currently running a Haltech interceptor on my mini and will eventually be running dual maps one for meth and one without. We should have everything sorted out in by the end of the month. We have been using different jets and meth concentrations and have had the car on the dyno and data logged on the road.

The pumps Julio (Alkycontrol) sells are high quality shurflo pumps that are custom modified to run 100% meth not all pumps cope with staight meth...that is the reason most meth kit suppliers suggest a 50/50 mix, to prolong pump life.

 

D-MAN, I'm interested in the Haltech interceptor. Please keep us posted on your progress.
In the days of mechanical injection, we would add a tablespoon, per gallon, of castor oil to the meth to keep the fuel from destroying the pucks & pump. I kept the same practice when my son started in go-karting - running meth. It sounds like you have the pump end under control - no need for castor & there should be no wory with any other component in the system - engine wise ( there's gasoline for the engine internals ). Where are you injecting the meth? If its in the intake, at 100%, I'd consider coating the inside.
If you are able to run dual maps you'll be able to take full advantage of the 100ron of the meth.
I like it

 

Will do
I originally had a Dimsport custom tune but it was a total waste of time and money (due to a tuner who had no idea what he was doing). So I went with a Haltech as most Aussie shops are very familiar with the system. I got a 23kW gain from the tune and I am now putting out some serious power (thanks to my Thumper head). There are a number of Aussies running Haltch's on their minis and have for years with no problems. It also has the advantage of running several different maps which I like.

Thanks for the tip...that is something else to think about

The idea is to set up the meth map so it activates automatically when the meth system is turned on. I also want a separate on off switch for the second map. This will give me the options of running the meth injection with the meth tune, running the meth with the normal tune, and running no meth. That way I will have all my bases covered! Can't think of another system that will allow for that...

That's cause there isn't 1.

Haltech was bassed in Texas a few years back ( 80's ). I have used several of their stand alone systems in the past. They make good stuff, not much learning curve for their software either.

You'll have to start a new thread when you get this project on the top burner.

i installed the alta v2 in my car today, got a crazy deal on it that i couldnt pass up...

after modifying the hood scoop a bit more than what was required i was able to see the entire core of the intercooler through the scoop when looking straight on at it...

also after reading this thread a few times i devised a plan to "seal" the intercooler to the scoop so that maximum air flow could be achieved.

As of today it as all together, the full core is exposed and it is sealed to the scoop, there is little to no room for the air to be able to run around the intercooler and not flow through the core, im not saying its "air tight" but it is much better off than with the rubbers that are provided with the kit, i would be interested in seeing how this setup compares to the setup they ran when testing the ic in this thread, from the way it looks and responds after heat soak it seems that it is performing alot better, still, im waiting to find a grs, but this will do for now. I'll post pics when i go back through and get the sealing set up more cleaned up and refined than it is now...

that is all..

 

The differences between the various a-to-a IC is minimal. Regardless of the IC - get the most air threw it possible. No doubt your is performing better than it did before.

 

thats what i was going for, that and the aerogel heatshield i think will help out with the keeping the temps down in the warmer weather, like i was saying i was in the market for the grs or m7 but this alta came up at a good price so i figured i'll try it out. We'll see how the car dynos when jan comes back around..

 

 

looks great.... now the real question is::::::::::::::::

HOW LOUD IS IT?

 

WOW - great looking piece.

 

How do you manage to drive with it? I know it is cold this time of the year over there, but doesn't it affect the coolant temperatures? did you have any problems with the pipes disconnecting from the rubber boots?

 

Graham, I WOULD LOVE TO TEST THAT SUCKER!

Seriously, looks really good! Love your quality. Let me know when your sending me one

 

And it's loud too?????? Cool.

If Intense doesn't want to test it I do

 

We should do it together!

 

That would be fun Fact is, I realy want to retire in the SW.

For testing you are in a much better inviroment than here, the NE. A good example would have been Wed - went to Albany - 39F ambient, IAT 44f average ( RT 90 @ 72mph with lots of elevation changes), this car loves these kinds of days. In July no 2 days were the same - had heat but the water could be a 20% change day to day w/same temp.

I'll send you a PM

 

Very interesting thread - thanks for doing the testing.

I haven't had a chance to read every response so maybe this has already been said. When it comes to the issue of pressure drop, isn't it important to consider the fit of the intercooler boots because the performance of any intercooler can be adversely affected if there is pressure loss through the boots? I've heard that stock boots fit better on some intercoolers than on others!

 

Thanks works and yes, the boots fitting nice and tight is always good. Most aftermarket intercoolers are made with the stock boots in mind from what I've seen.

Pressure drop was one of the things I wish we could have tested. Just didn't have the tools to do it maybe one day I'll revisit it. We had a great time doing this and we learned a lot

 

Can anyone tell me how much room there is between the Forge Intercooler and the hood? and, what is the actual core size?

Thank You
