Specs on the vehicle are an 84.5mm bore M54B30 with a balanced crank, PPF H-profile rods, 8.5:1 compression CP pistons, and ARP bolts. The cylinder is ported by PPF with +1mm Supertech intake valves, stock sized inconel exhaust valves, with PPF valve springs and retainers. The turbo making the power possible is a Precision PT6765 .82ar. The motor also gets S50 independent throttle bodies. The car is tuned on a standalone and runs E85 fuel.
Pictures of the car and dynograph below along with a bit of history on how it has come along and gotten to where it is. Congrats to PPF and @JimmyOberg :
This is the car back in 2009:
Looks pretty fast yes? I find the shape of it very aerodynamic.
In all seriousness, it's gone through quite a metamorphosis, starting like this:
At this time Jimmy was looking to do a very high spec N/A build, including the fitment of the S50 ITBs pictured above. (This was an experience we shared; the adaptation of an ITB manifold onto an M54) To say that this project was just a pile of parts bolted onto the car would not be doing Jimmy (or PPF) justice. The ITB project was pretty serious, with a lot of Jimmy's time spent here:
During the summer of 2010, Jimmy began to talk about doing another turbo project. (His previous toy was a 700hp turbo E34) So it wasn't a surprise in September of 2010 when the following build plan was announced:
*SPA Exhaust manifold
* Precision SC6262 Billet Turbo
* Presision 44mm Wastegate
* 3" Steinless exhaust with 2 SIMONS silencers
* PPF 50mm BOV
* 450X300x75 Intercooler
* BMC Airfilter
* Link G4 Atom EMS
* Audi ignition coils
* Siemens DEKA 895cc injectors
* Bosch 044 fuelpump mounted in the tank.
* Aeromotive AN6 regulator
* Modified fuelrail
The goal was 450rwhp on a stock M54B30 bottom end on E85 fuel.
Building the turbo manifold:
Installation completed at PPF, and on the dyno to start tuning:
Super clean engine bay:
Then I got this in an email, and I knew Jimmy and PPF must have been happy:
So that takes us to October of 2010.
The next step for the car was an M3 body for 2011:
Also in progress was a new turbo manifold and built engine:
Also, in the spring of 2011, a PT6765 turbo was added to the engine along with the turbo manifold pictured above. This netted a solid 516rwhp at 1 BAR (14 PSI) of boost on the stock M54B30 engine.
Over the winter of 2011/2012, a new engine was built to the following specs:
- M54B30 Block, 84.5mm bore
- CP Pistons 8.5:1 CR
- PPF Rods
- PPF Ported head
- PPF Valvesprings + Retainers
- Supertech +1mm intake valves
- Supertech inconel exhaust valves
- PPF M50 turbo cams
- VANOS delete
- ARP M12 head studs
- ARP for the maincaps
- SS Exhaust manifold
- Precision PT6765 Turbo
- Precision 46mm Wastegate
- 3.5" SS exhaust with two SIMONS mufflers.
- PPF BOV
- PPF Fuelrail
- Bosch 1700cc injectors
- Aeromotive AN8 FPR
In addition to the above, the S50 ITB manifold pictured previously was added, although using the S50 OEM plenum and runners instead of the billet aluminum pieces.
In April of 2012 the car was sold to Fredrik the current owner.
In May 2012 the car made 513rwhp @ 0.95 BAR on the built engine. (8.5:1 compression ratio) I'm told the car remained in this state of tune until December 2012 where it made 570rwhp @ 1.2 BAR before a head gasket issue arose.
Then the stock head gasket was replaced with PPF Coppering head gasket mentioned previously, and we now have an incredible M54 world record!
