Finally got a new "better" quality radiator. And by that I mean, it cost more, hopefully the core is not epoxied like the last two crap Chinese radiators. They promised it wasn't....




Polished it out. You can see the new head sitting there too.



Sneak preview of the intercooler I'm building. Man, Mini's are tight when they are bagged...

 

It is a smaller intercooler (technically an aftercooler), but it is plenty big for the CFM that the 22re needs. You have to remember that the CFM does not go up as boost is added unless the gas is allowed to expand to a lower pressure.

While it might be prone to heat soak easier, the smaller core is what will fit.

And as far as the Water Methanol negating the need for the intercooler, that is also mostly true, except that any heat I can dissipate before the methanol is added only adds to the fuels ability to cool the charge, AND I can spray less because the temps are already under control at lower boost. Because of that, I can raise the boost number at which the methanol starts getting added, making the amount of mixture I can store last longer.

What are your plans for your turbo install?

 

If you max out the volume that your head can flow at 1 atmosphere, then boost is the unused volume being converted to pressure. So, your CFM is not rising, your boost is. Pressure is unused volume. Now, if you unpressurized 100CFM @ 12 psi of air you would have more volume than 100 CFM @ 0 psi, but we aren't talking about that. Once you start adding boost, the CFM post compressor won't change, the extra volume will be converted to boost.

 

But I think you might be looking at this differently than I stated. I specified the need that the 22re has as far as theoretical flow. I read recently (wish I could remember where) that the theoretical maximum volume the 22re could flow was something like 265 CFM due to it's low VE.

So, 265 CFM is 265 CFM at 0 psi or 100 psi.

 

Got my intercooler and plumbing done. Now, just some minor tuning, and a few other little things in the engine bay and she's done. Weird, never thought I'd actually say that. (I do need to build my water methanol tank.)

I also painted the intake manifold with my new Harbor Freight airbrush...









You can barely see the IC in the front of the wheel well. I have to play with some ducting to get a bit more airflow through it, but the temps under boost have dropped 50 degrees, which is great for the airflow it sees. If ducting air to it helps, and I can't find a clean way to keep the ducting there, I have a few James Bond ideas for increasing air flow.

 

It kinda has some ducting from the center openings in the bumper around to the IC. I pickup up a buddy's go pros last night and plan to do some testing to see what kind of air flow I currently get. As I said before, it has made a big difference in temps under boost, but at idle cruising slow in traffic, the temps are still higher than I'd like: 120-140 ish. Then I have a few ideas to try, one of which is the same as your's Nam.

 

So far so good. I've adjusted the shift cable to raise the shift points a bit to provide for a bit firmer shift, but other than that, I haven't had any issues.

 

Not sure yet. I did some tests with my Gopro and a few streamers behind the core to see what kind of air flow it sees. There wasn't much difference between doing nothing, pulling the turn signal, or adding a small scoop. There seems to be a bit of flow through the opening of the middle of the bumper around the bumper brackets and out the wheel opening through the IC.
So, I may add a puller fan to the core just to make sure there is adequate flow at lower speeds. If so, I'll use one of the programable outputs from the MS2 ECU to trigger it on above summer ambient temps.

 

Well, was doing some routine maintenance on the truck when I found this...











So I built this for a temporary fix until the turbo gets back from Turbonetics. It will be covered under warranty.

 

Thanks. It feels like I'm heading backwards right now. It's going to be a long 3 weeks.

With the turbo off, the exhaust sounds like poop.
