Any progress on V8 engine swap options?

My charge coolers are at the sides of the engine. I looked into having intercoolers by those side vents, not enough space and I'm not convinced they draw enough air.

I'm not planning on making any changes to the charge cooler system at this point. The only potential idea I have is to plumb in a heat exchanger that uses the A/C to cool the coolant. Tesla use one for their battery cooling. I've got one on the shelf. Because you use the a/c to chill the coolant you can get it down to bellow ambient temperatures. All the same charge cooler limitations apply though, you'll put heat into it quicker than it can recover, if the coolant pump isn't fast enough might not improve things towards the top end of a pull, etc. You basically just start from a better base line. If I could plumb it in myself I'd give it a go but I haven't been able to find the fittings. Ultimately, with the WMI proving so effective, what's the point?

I'm not sure if I said it on here already so if I have please forgive, but I don't like the idea of using wmi to fix a problem. The issue there is that of you run dry or your system malfunctions, it may cost you a motor. I'm certainly not trying to criticize your setup, I think you've done a fantastic job.

I've got a level sensor wired into my screen wash light so I'll know when it runs low and have got a flow sensor which will flag an error if a pipe came off (set up as a boost cut) and also I have knock control which will pull timing so I don't consider it much of a risk.

Well I’m going to test this theory; the red box in this image is about where the side vents are. I am hoping that the vents can supply some fresh air to both the air filter and to the area around the charge coolers in the front. I am thinking of augmenting with some slim 6 inch fans to increase flow. If I find a recipe for stable IATs without AC cooling or WMI, I’ll let you know. Though I do agree that WMI is pretty magical.



The stock ecoboost turbos should put me in the B5 S4 k04 ballpark with great low RPM spool, but there are some drop-in upgrades that I’m pretty excited about too. Here are some 42/56 units that should be comparable to the RS6 turbos that you are running. One step at a time though… need to get this embodiment put together before really pushing performance.

Fueling is currently my bottle neck… I’ve still got stock injectors and fuel pump in my build. Which injectors are you running?

I've currently got my air filters sitting in the side ducts, I don't think they'd supply enough air for air to air intercoolers though.

I'm running a cheap 340lph fuel pump and Bosch EV14 550cc injectors. They are OEM fitment on some cars so can be had cheaply. I'm near the limit of the injectors, they are hitting around 85-90% duty cycle.
