Good point. It just seemed like less that running everything from the front to the back - and you need scavenge pumps for the oil anyway, and maybe a water pump?

You could run a water pump if you wanted...but it's just one more thing to add to the complexity of the system. Boostlogic does not run water pumps: they've been specifically told that merely having water in the cartridge-core to transmit heat away works well enough & that water circulated heavily through the center cartridge is nice but considered over-kill.

So do you (either of you) currently use coolant flow from the front of the car?

Johns kit does use coolant flow from the car.

Keep in mind that johns kit is a front mount set up

I did: works fine.

Depending on how its plumbed I bet that could really wake up the heater inside the car. ;)

Mine too, works well.

To be specific, I run a pump in my setup that also remains running for 5 minutes after the ignition is switched off. This helps cool the chargers down after shutoff...that's the worst time for the turbo due to heat soak.

That is a yes .

Any updates??

Still working on it. I gutted all the original turbo oil and water lines on the car as I'm replacing them with braided stainless lines and Earl's fittings. Re-routing some wires for the boost control unit and scavenger pump inside the car instead of running them under the lnegth of the car by the exhaust as they were when it got here.

Installing extra breather ports in the valve covers for the crankcase vent system to minimize oil lifted out of the engine.

The exhaust and turbo are hung back into the car and tight. This AM I will be fixing the muffler and installing it back into the car and then running some of the braided lines into the car.

The EZF is going to be upgraded with a new MAP sensor so I have some resoultion over the map from vacuum to boost. Existing MAP sensor will bottom out when vacuum is completely pulled...leaving only one row of RPM cells to tune by when in boost...real crappy for runnng multiple boost levels. The WOT ignition signal will get a vasectomy and I will tune it on one map only. I will be installing a 2 BAR sensor so we have ignition mapping capability to about 15 psig and can still have off idle vacuum mapping. In addition, there is some work being done in the UK to get SuperMAF capability for the 86.5 system and that should be done very soon. I'm sending two MAFs over there today to have them upgraded to SuperMAF. When it was running this summer we were nearly pegging the map on just 6-7 psig...that leaves no place to tune on 12 psig.

Big project for sure...nearly a new development project. I'm anxious to see how well it will run with all these upgrades. We may have added a tiny bit of lag with the bigger plumbing and intercoolers, but there will be big dividends upstairs for sure. The bogey is over 500 horse on the tire and I think it will do it.

Sweet post, thanks for the update & work, keep the info flowing as you have and as you go!!
Sucks being over here by myself as a Hp motor head and learning as I go!!

What ever happened to this project? Sorry if I missed another thread, but I'd like to know how Abby likes it:)..
