water to air intercooler

[turbo800]

Here's a link to the the Bosch pump Brad mentioned above:

You can check out Islandoo"s thread in the members build section, He did all this over a yr ago and would never go back..

Fred, slow down the pump some , You can use an aeromotive fuel pump manager to regulate the voltage to the pump and lower core temps another 30 degrees. The coolant flows to fast and using a restictor or thermostat is
intrusive to the fit and finish.

jegs has it all as per usual...

The managers control can be remote or dash mounted to adjust on the fly for differing condtitions.. delta delta delta..Burke LOL

Once you go this route you wont ever look at an air to air again..

little cheaper here

thanks for all the info

just waiting on pump to arrive before install, and want some seat time with new intake snorkel to see what that has done to charge temps before going with water to air system

looking at location to install of the barrel exchanger, i was planning to install where delete pipe had went, but it could be to tight?? has anyone have any ideas on mount location... thanks

looks like a aera of support is needed to house it

If you're into calculations, shoot for water flow through your cooler with a Reynolds number slightly into the tubulent range. Any less and you will not transfer heat very efficiently. Any more and you will be pushing with larger head pressures than you need and will start to generate heat through pumping. I work quite a bit with freezing systems and this is what we've found in the field.

Curious to see how it workls out for you

brad what was your findings on using your air to air intercooler compared to the others mention here at 10lbs

Fred W.
We currently use Air/Water in 5 applications. We are also currently testing Air/Water systems on the e-Tec. An A/W system will ONLY be release if the testing performs within our design parameters. Our current system was not intended to have an A/W system because BRP had certain requirements for the system specific to the Race Team.

Current water pump is a Bosch pump. Be careful of the amps!

A 1.1 psi pressure drop is probably not accurate and is excessive.

Here are some of my calculations and assumption that may be helpful.

800cc E-Tec, 7000ft or 11.3psia, 34f Ambient air, 110f engine coolant returning from tunnel (from test data), Water temp on a dedicated system 32f (again from test data), 10psi, 1.88 P/R, 12.8afr, 72% compressor Efficiency, 70% intercooler efficiency, and .5 pressure drop.

No intercooler, 307cfm, T2 170f (Compressor Out), 170f Charge Temp, and 213hp at attitude not corrected.

A/W, 363cfm, T2 170f, 73f Charge Temp, and 251hp

A/W W/ engine coolant, 329cfm, T2 170f, 128f charge Temp, and 228hp

No boost A/W, charge temp 33f

No boost A/W w/ engine coolant, charge temp 87f

Max delta w/ engine coolant 41f

Max delta w/ closed loop coolant, 40f.

Anymore info on this? Thanks.
