Best / most efficient intercooler configuration ???

[J-1]

As above, what's the best / most efficient set up possible, taking in to consideration air flow?

Are rear mount intercoolers better or worse than BMIC's?

Does anyone have any photos of the Phoenix Power style rear mount intercoolers, that shows how it positioned and how pipe work is routed?

Considering a change of design on mines.

Let's put it another way. You'd have to really, really, screw up the design of a FMIC to make it as bad as the average SMIC. With SMIC everything is against you: air flow, size, heat soak. But you don't have much choice!

Renault and, I think, Lancia, played around with combined charge cooler/intercooler set ups if you want to get really creative. Otherwise you can leave the IC fan on all the time, fit a bigger intercooler, shrouded, bigger fan, phenolic gasket, do some heat sheilding, etc.

The main phoenix power demo car (the red one) actually ran a front mount intercooler set up. I would imagine this would possibly provide better change temps than a BMIC but they had to run the pipework right through the passenger seat area and to the front. That's a massive distance. And I dare say had a little more lag due to it than I'd personally want to have. But that's what the gearbox is for

I take it you mean the ones that drop right out behind te rear number plate but instead of lying flat they are sitting upright?

I dare say that they would be routed similar to mine but the intercooler is sitting at a different angle. (Rotated 90* on the pipework sitting down through the bootfloor without the ducting)

Intercooling on an mr2 is tricky, I ran a horrible greddy copy and got 50c+ intake temps Then added 50/50 water methanol and got 25c and lower, the more i was on full boost the colder my intake temps got (my record was 18c on a plus 25c ambient day) .
My top tip for intercooling, plus many more benefits , 50/50 water, methanol injection

My setup is so simple, at 0.4 bar it starts spraying through a 0.7mm jet, cost me £120, bargin

Ps. Much extra horsepower was found using this setup

I run a greedy copy on mine, do you have any more details on your water/meth system?

How do you monitor temps?

What size tank did u have and how long did it last?

Also where do u get the mix from?

[GeorgeL]

Buy medical grade methanol and mix it with council juice

Tank is 4 to 5 liters off the top of my head. Dont sound much but it lasts weeks of on road driving.

Mix, eBay search methanol 5L £18, 10L £25 delivered. If you live near enough to pick up, 25L can be yours for 25/30 quid

Water, I use reverse osmosis water because we keep marine fish but most use distilled water very cheap on ebay £24 will get you 25L delivered.

Temperature monitoring, I use a k type thermocouple like this.. http://www.ebay.co.uk/itm/TM-902C-K-Typ ... 461be2eced

Looks c*ap but does the job, plus no need to wire it to the car, it has its own battery. bought mine well over a year ago and its still going strong.

I run a simple Auamist s1 with race pump, Like this .. http://www.volvoforums.org.uk/showthread.php?t=154782
Old technology now but still works great.

Are you using the original ecu and were do you spray it.

Yes and I also used a mines ecu

Wow this thread has gone off a tangent!!

The OP was asking about boot mount IC Vs rear mount IC.

Where front mount IC and side mount ICs mentioned in this thread have come from is anyone's guess.


I have run neither, but i imagine this.
Rear mount, it's mounted outside so a plus, but will sit closer to the exhaust (heatsoak), with that and subframe blocking potential airflow, it will be hard. I'd expect a custom duct to help direct air to it and block off radiant heat from exhaust.
Bmic: confined to the boot, would need airflow to and out sorted via vents and fans. Still have exhaust heat worries. But should be less pipe work so less possible lag. You've already gone this route, so maybe think of better airflow and/or add water/meth injection.

I'd stick with bmic as you've already cut out stuff for it.

With boot mount Jim, a lot of guys route the exhaust out the side.

I put together a frozen boost cc system a little while ago, worked well.
I wouldn't call it expensive though or hi end.
