Hi Boost C55
On July 15th, I will let everyone know if a 14-18psi C55 will become a reality.
The key question is if DynoComp can overcome the MAF sensor problems associated with running high boost through an 82mm TB. The E55s don't have this electronic sensor because they use physical air pressure to control the throttle.
If they can do this, then all SC'd or even turbo'd NA55s will have a much higher power ceiling and will be able to compete directly with heavily modified OEM 55K cars.

A set of E55 pistons and rods with ported heads and forged valves cost less than $4k + $1K for labor so not a bad investment to get it on Par with the most heavily modded 55K cars but with a lighter chasis and better handling. Of course you still need an aftermarket SC kit.

This sort of thing is getting pretty common. You can have a used ecu unlocked and married to the car. People are switching engines and transmissions or just engine or just transmissions. At this point I would not even consider a kleemann kit. You can get a used 55k motor and ecu for about the same price and install it. Start from there on the tuning. Heck there is a kid with a 55k engine in a c43 on the east coast and a guy that put a 55k engine in a cls500 that has the newer 7speed transmission. There has been someone in California with a c32 engine in a c class coupe for years. I know a guy that has a om606 turbo diesel from a 1998 w210 with the factory diesel engine management and a 722.6 in a w140 chassis s class that I think is a 1993-94.

What's the verdict????

Not really following Robert's car, but I see it at the shop when I'm there. Once or twice a week. Last I heard the wiring harness needed to be completely replaced. Pre-existing problem. I'll see I've Rich @ DC will answer his phone and get some updates.

I was supposed to pick up the car today but they still need to tweak the tune and possibly install the larger injectors as the car ran out of fuel at 3500rpm with an AFR of over 14+. Surprisingly, with both the 170mm crank and 65mm SC pullies, the boost only increased to about 10+psi. With the stock 150mm crank and 70mm SC pullies, the boost was only 4+psi so the modified pulley combo raised boost by 6psi.
According to my math, the boost should have been near 14+psi (1bar) but I guess the ported heads, larger valves, 82mm TB, lowered 9:1 CR, Long tube and dual 3" exhausts and 200 cell race cats dropped it back to 10+psi.
According to Rich, the car runs incredibly smooth after the wire harness was replaced and a custom throttle body inlet was fabricated and installed to smooth out the intake air flow.

Since "boost" is an indication of airflow restriction, this just proves my point that more airflow is very important. The more you increase flow, the lower the boost will be. (and the more air will actually get into the motor)

I would say failure as to time but final verdict is TBD until the end of next week.
I never realized how diifficult it is to get "hands on" time at DynoComp. They are just flooded with business but they did spend significant time debugging the electrical problems unitl finally solving the issues by replacing the burnt wire harness.
