3 liter update- 2000 miles and counting
Posted: Tue Apr 05, 2005 10:58 am
Well I am happy to report that the 3 liter has ran for it's first solid month without being touched!
This big engine has amazed me. It's smoothness, its brute power, its cool running and it's 25 MPG!
I have logged 2500 miles on this baby, been giving it hell as well as driving is smoothly... I even put a dozen full drag passes on it at the SE Drag Day and still haven't adjusted it yet! Not even tweeked a carb!
Here are some averages that I have kept up with..
Oil consumption= 1.5 qt in 2000 miles
Avg Head temp= 305(what a testament to the DTM! This is a 10:1 engine)
Avg Oil Temp= 215 (it only has a 24pass mesa cooler and the stock TIV cooler in the DTM)
Avg MPG= 25 highway
Flywheel HP= 231
Flywheel Tq= 235
Wheel HP= 196
Wheel Tq=195
What is totally astonishing is that I am sure this engine would live atleast 80K miles with these types of averages, maybe 100K! The entire project is astonishing and it still has more left in it!
I have pretty much parked the 912E for a few months to get it back in concourse shape after she turned 71K miles with no maintenance.
I plan on driving this car the rest of the summer and racking up as many miles as I can before pulling it for a cam swap and some mods to the heads that will allow us to run a ratio rocker. I then plan on testing the engine plus heads against these as well as a set of 2.0 914 spec heads that have had every trick known to man in their composition...
I will add EFI and 52mm Throttle bodies by the end of April and a full data logging system as soon as my customer gets it finished for me... Then I can share data plots from actual in car testing much easier.
