First ESS Supercharged N52 Z4 dynoed

[bmwZ]

any engine bay pics so we can see what the hardware looks like??

Yes, of course

There was no space for the airfilter to be mounted in front of the supercharger. So ESS have buildt a new steel tube before the airfilter, they have also changed the supercharger belt position vs E90 setup. Having electronic steering, it also have a different belt. Can not feel any heat soak, but will try to run a cooling line to the air filter soon.
The air have a shorter way into the supercharger now. That gives more power if it's not running to hot.

Is the kit available now to buy? I assume it is developed/finished? I'd like to order one, so have been watching your threads with interest.

Not yet, but they will produce a kit for Z4 soon.

That really is an interesting layout... probably be too much effort/ cost to pipe the airfilter next to the radiator.

It is not enought space on the Z4, the N52 engine are mounted closer to the cockpit than the S54 and M54.

Just thinking back to when i had my front bumper off.. where the M brake vents are there was a lot of space in that vicinity.

Yes, that is thrue. But it is space between supercharger and struthousing that is the problem...

yeah not to keen on the air filter placement tbh...... thats sucking in alot of engine bay heat.... on a non intercooled car i think that needs some development, maybe you could use some sort of slimline carbon airbox unit that has a flexi piece, loops back where you can't see and take from low bumper.. however its a relative minor, the rest of it is super clean looking as i expect from ESS. That engine with a blower is a win for me.... must be awesome! Can you make some video clips of how it idles and sounds with the blower reving and other situations ??

You would get more benefit from cooling the air post supercharger rather than pre air filter, its the compressing of the air that heats it up so i think a cold air feed would only have a small effect, have you room for a small air to air intercooler in there?

Bonnet vents??

To be honest for a first stab im impressed.

You could always get an air duct from the grill to the filter and make a heat shield on the engine bay side of the filter

That will be my next mod

or to really chill it down.... water injection?? bmw using it on their new gt4... could work here too

That will be my next mod But don't think bonnet vents will be clean enough

Yeah, but very little space...

 

[Beedub]

water injection uses little to no space under the hood.... most systems lot mount a tank or use the washer tank, its literally just a line with a atomised spray nossel, very neat and very easy to implement.

 

[NeilP]

That bay looks fantastic.

 

[Brasseye]

Looks great. Got a drive by video yet ?
The linear power of super chargers are just so drive able compared to hi boost turbos

Thanks for sharing.

I have looked around for maby doing water injection after you came with the idea. Thanks

Here's my water/meth injection:

Apologies for the dirty engine bay, as the car was a daily driver.

The water helps cool the intake temps while the methanol is effectively like running race gas all the time. The progressive controller is set so the spray comes on at 4 psi on my car (9 psi is max boost). I used about 10% of the water/meth tank after 2 full tanks of gas. It doesn't take much. Setup is key.

 

[bmwZ]

Thanks for the pics and info. Do you have a nozzle before and after supercharger?

Think I will do that in spring time next year

 

[pokeybritches]

Only after. The nozzle should be positioned so it's not spraying directly onto any sensors (I'm not sure what sensors the N52 has). The trunk-mounted tank and pump are actually fastened to a carpeted board, so I can pull the whole thing out in less than a minute. It's very clean.
