ESS VT3 Supercharger - Low Compression M3 S65 Engine Build Has Begun...

Drew’s VT3 project build is the end result of our work over the past 2 years to design a low compression option for the S65 motor. This design will allow the S65 to run 10:1 CR which will allow the use of higher boost safely on pump fuel. A requirement in our design process was the ability to use the OEM Alusil cylinders in order to achieve OEM oil consumption levels, cylinder noise and engine longevity. The only way we feel to do this is to keep the stock displacement and use a custom made Mahle Alusil spec piston that will allow a factory seal by using the OEM BMW piston rings. This requires a motor that is in perfect working condition as we use the original block and cylinder machining. We do not sleeve or bore out the motor for this upgrade as this will compromise the Alusil cylinder seal quality. As an added precaution we also upgrade the rod and main bearings to add another level of safety to the design.

Outside of the motor we have designed a custom fuel delivery system that will allow proper fueling for the elevated levels of boost we will run and a custom belt drive system that retains the factory tensioner. The combination of these upgrades will allow the Vortech V3 supercharger to make 700+ HP on our existing VT2 hardware while retaining OEM quality drivability to the vehicle.

That is about as perfect as it gets in describing the VT3 build process and your approach. This is going to be A LOT of fun, looking forward to seeing you at Targa Trophy next weekend.

so that's when the debut will be

so anxiously awaiting the numbers and everything

Sounds like a plan.

[0-60Motorsports]

Sounds awesome! This buils sounds like a solid one. GL Brother and looking forward to it even more now

[henryyxyu]

subscribed! interesting build!

[flipm3]

This looks like an incredible build!! With ESS' experience and knowledge, I'm sure that your car will be up and running with extreme reliability. I am looking forward to seeing things progress.

Out of curiosity, have you guys taken any closer look into the headers? I know RDSport developed headers, but unfortunately without much popularity or success. Do you believe there is any room for equal length-long tube headers to increase even more power?

Again, thanks for sharing!!

[KiokenM3]

looking forward to this drew, good luck!

good question. looking forward to Drew or ESS' input.

[bubu]

...truly insane

any concerns about the DCT not holding up in 700whp land?

[1cleanm6]

Wow, congrats!

When youre done....you and Josh need to set up a match.

Just a ?... Youve spent some serious money on this engine, how come you never thought about purchasing a porsche turbo?

Will you guys still be using the Vortech V3? ... What if you guys push it past the 750HP limit?

Thanks! The S65 headers are very good as is, I have no plans to go with AM headers.

Josh is a good friend, no doubt we will do some pulls. No interest in 6MT, I wouldn't mind a PDK, but too much IMHO, I usually get a new car every 3-4 years, but I plan on keeping this one for a good while, but you never know.

Thanks Man, we are using the V3.

The V3Si is capable of 775HP out of the box, even more with a custom impeller.

[Bob MG]

Drew, love your work!!

AJ, I want this!! Problem for me high altitude of 5500 and required RPM of V3 blower to make 12 psi. Will you be able to provide a different higher rated Vortech blower that can produce more boost? I would need blower to spin at RPM equal 16psi to make 12 at my altitude.

Last Q.. Is there a new high boost pulley and belt system which ensures no slipping? My 88mm pulley occasionally slipped on my last set up

[dizzyj]

Just out of curiosity, what would be the difficulty of going with a flat plane crank while your in there? Wha benefits would you see?

[datbimmerdoe]

this is how u do it! CANNOT WAIT!!!

This is a great build. Can't wait to see it completed

And just out of curiosity, what do YOU think the advantages would be of:

1) Scrapping the cross-plane and having to find a custom-ground flat-plane crankshaft (which would radically change the internal balance and configuration of the engine)
2) Getting custom camshafts to match the firing sequence of the new configuration.
3) Practically re-creating the the entire ECU.

$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ later , what do you have? All this so you can think your car "sounds more like a Ferarri"??

C'MON MAN

so excited about this.......

interested in fueling setup and pulley setup, my vt2-500 on my z4m uses a new ess billet crank pulley and im seeing no slip on my 85mm pulley ;-)

really excited about this, awesome news Ess....... the v3si is VERY close to Trim so their should be no need to swap the blower.....
