    ESS VT2 550i - 6psi 420rwhp/392 rwhtq !!! Video Pictures

    Found this to be very awesome because I have a 4.8iS that might get graced with this beautiful ESS r1900 (ZL1) supercharger someday. Especially after these stunning results...


    First dyno run was only at @4-4.5psi due to cat-less long tube headers. Apparently the factory exhaust on the 550/750/X5 is very restrictive. He made a respectable 400whp/360wt at 4-4.5psi. The kit advertised as he got it (32" pulley) claimed 7-7.5psi.



    After the installation of the smaller pulley 32" to 30" he went from 4-4.5 psi to 6psi

    This is what it put down. Still 1.5psi short of where it falls and not lean at all!!

    Not bad, was not sure if this was still coming. 420 whp is decent, glad there is an n62 option.

    Whose car is this? Would do a bit more without those big HRE's.

    His name is kernelmaker on bimmerforums. He only has a few posts but has kept his thread up to date with pictures/videos etc. I'm sure he'd respond to a message to get on here via youtube or what not.

    This kit is just oh so tempting. The power under the curve is awesome and at the advertised psi 7-7.5 assuming he gains something similar from the 32" to 30" pulley with the 30 to 28" he has sitting there he's looking at a bolt on 440whp/420wt @ only 7.5psi give or take.

    He's still running the stock exhaust?

    No supersprint catless longtubes, quad tips. Nice set up, that's why the boost was only reading 4psi when he originally put it on.

    Myb N62. I knew that, you can edit

    He said the whine definitely got louder during the pulley increase, should definitely make a nice scream at 10psi

    That's good. Combination of V8 rumble with SC whine is what you never expect from a BMW lol.

    This is a roots blower though, not sure how efficient it will be at those higher boost levels.

    I'd guess pretty well because we all know what CTS-V's and ZL1's are doing with pulley changes, and I believe they are using this r1900

    Ya but they make much more power when they switch to a twin screw.

    Also, this is higher compression.

    Hi guys. Cool forum you have here...and there is even an N62 section. Click here to enlarge

    The 21 inch wheels are a bit overkill but the car actually feels quicker with the HRE 21's on versus the OEM 18's (with RFT's). Even though the rolling circumference is a longer on the 21's than with the 18's, the 21's are significantly lighter than the 18's. Would be nice to find some 20's to clear the 405mm brakes or downsize the brakes to some M5 brakes and run a lightweight 18" wheel/tire combo all around. Then that way we could put the original fenders back on so it looks more like a 550i again.

    The car is a pleasure to drive. Here to answer questions if you guys have any.

    Nice ride, you must be enjoying it.

    Let us know when you do the water/meth.

    Decided not to do the meth route. Decided to always fill the tank with Trick 101 unleaded and run a KillerChiller. Below are a few photos I was able to snap of the KillerChiller.

    The air conditioning system is basically used to cool the superchargers intercooler by routing coolant and A/C through that little black box. Might run a bypass valve to remove the heat exchanger from the coolant loop since coolant temps are much lower than ambient and the heat exchanger now works in reverse with the lower than ambient coolant temperatures. After a nice drive you can open the coolant tank, stick your finger in it and it feels like a cold beer.

    Very trick!

    How is it working? Do you honestly feel a difference?

    The temperature of the coolant is noticeably cooler when using the finger test.

    One advantage of the KillerChiller is that the power does not feel reduced after the first couple pulls like it used to before the KillerChiller was installed..the power stays. Also, on the dyno we saw the power increase pull after pull when the KillerChiller was turned on. This is opposite of what you sometimes see with heat soak.

    The noticeable difference in power was felt after running the unleaded 101. The car idles smoother and feels stronger.

    A couple more. Slow work in progress. Hope to have the block stripped in the next week or so.
