Hi guys,
It's been a while since i've posted on the forum, but have been checking in every now and again.
Some of you may remember when I converted my e34 540i from automatic to 6 speed manual in 2010. 5years of fun was had going to track days and enjoying her.
In late 2015 I was thinking about supercharging and started looking into options. Unfortunately I couldn't locate one, at which point I decided to build an M60B44. This is using the M60 heads, valve train and timing equipment and a M62B44 bottom end from an E38/E39 etc.
I chose to regrind the M60 cams to something more aggressive. Standard cams have an advertised duration of 246 intake/242 exhaust. Franklin Cams reground mine to 272/252.
The M62B44 headgasket was used and an oil feed for the original "U" timing chain was blocked as the M60 timing guides are different.
Most things that could be replaced, were replaced.
Several months into the build, I found a supercharger in the USA and thought to myself...why not? It took approximately 2months to arrive, but this gave me plenty of time to actually get it running and iron out some of the bugs. The supercharger arrived ~3weeks ago.
The clutch setup has been custom made/modified by Autoclutch in Auckland.
I have now done 1300km on the rebuilt engine, and it definitely pulls stronger in all gears up to the current redline.
I tried to dyno the car 3 weeks ago, but unfortunately the radiator blew a hole just before the dyno run was about to start. New radiator and heavy duty fan installed as a precaution.
Tomorrow (27/6/16) I have a dyno run to see how it pulls out of the box. This is using the factory ECU/DME for the M60B40. I know I didn't need to do it as I will be installing the supercharger straight off the bat, but I wanted to compare with my Auto dyno run in ~2009. Another run will be done after the supercharger and piggy back ECU install/tune. Aiming for ~400whp with the blower.
A 320lph AEM fuel pump and 42lb injectors arrived last week.
Enjoy.
