Has anyone tried placing the water heat exchanger where the stock Lotus Exige intercooler mounts?

I won't be installing the Hex, just the water heat exchanger with the fans that comes with the REV400 kit.
BOE has it being mounted on the passenger side above the wheel.

That is the hex. You're just opting for the standard side mounted hex as opposed to the optional front mount hex. Unless I have no idea what I'm talking about.

The Hex for the front is considerably different, and larger.

Yeah, the Hex front mount is for the high horsepower REV400 builds, which are typically utilizing a built engine. IMHO unless you have a built engine you can't take full advantage of the REV400's capabilities, unless you want to roll the dice and are willing to blow a stock engine.

Yea I understand that, just clarifying that it's still a hex. It's just the side mount version.

I was just confused because use you said, "I won't be installing the Hex..."

How hard is it to install this rev400? Can it be DIY for someone with basic maintenance skills (i.e. oil change, brakes, fluid flush)? Or do I need a shop to do this install?

I am fitting the side mount hex and the front mount proalloy (no cut, keep a/c) heat exchanger in series.

Side hex first then front hex. Will do a check to see if the front hex on its own is more efficient. The proalloy radiator kit comes with sucker fans rather than pushers.

Don't want to chop the front crash structure and want the air to travel through the initially intended path. The pro alloy stuff is exceptionally made. Just waiting for an ECU to run this magic.

Point of clarification, the heat exchangers were designed around boost...

The side mount that the kit comes with is for ~10psi boost in track conditions. That's the boost setting for stock motors. It's great for that...

On lower compression built motors, we'll sett he boost to about 15psi and the front mount is requisite for that level of boost and best performance on the track. We have many folks running the side mount on 15psi on the street. The side mount can deal with short bursts of 15 psi, but it's simply not big enough nor does it get enough high pressure air to shed the heat generated by 15psi boost for long periods of time...

The front mount is big enough, that we're shedding adequate heat on the REVX in track conditions, which runs 25psi boost!

There's no reliability problems on the stock motor with the way the kit is delivered. We just can't run as much boost (boost equals power) on the stock motor as we can on the lower compression built motors. The heat exchanger should be increased in size as boost goes up...

Hope that helps.

I'm excited as a little kid, can't wait till the kit gets here....
I have almost all of the removal work done, and the surge tank installed.
Keep up the great work Phil.

The REV400 kit arrived last Wednesday. Installed the REV400 over the next few day's, I had previously installed surge tank, new radiator, and rear oil cooler. Took car for initial drive yesterday. What a difference. The change in power and torque is very noticeable. I highly recommend this upgrade. Not that difficult to install, and everyone at BOE was very helpful with my many questions and concerns.
