Yes that's a safe area to be in. Now take into consideration what loungn14 said. Octane!! That is very important. When I race my car is either on Torco 100 which has an octane rating of 100 or VP 109 race fuels which has an octane rating of 101. My car has 9000 miles and 90% of those mile were on race fuel. For everyday NORMAL driving then a mixture to run a 93 octane is forgiven by the ecu, but not in WOT driving. So if your tuned anything higher than 12.5-13.0 it should be mandatory to use 100 oct race gas IMO. You will have people heavily mod and still use regular pump gas. Might as well throw a match in the tank.

 

I've been so busy I am not on MBWorld.org very often and if I am its for a very short period of time.

Haha, no worries I expect nothing less. Hopefully you won't be gone for good. I like a little debate, it makes things interesting and far less mind-numbing.

 

that's the way i've always felt about any car i've owned. if you want to race, buy a car to race...

trailer...race...garage
trailer...race...garage

then your "driver" doesn't become your mod-race-break-repair.

 

That's exactly what I intend to do with the 55', and the occasional drive-in car show.

 

Huh? Since when is installing a single bolt-on considered highly modified? I think most would agree a highly modified engine would have headwork, cams, larger valves etc.

 

When your talking about a mercedes supercharged AMG motor that is already modified from the factory. It already came with the best components available and still reliable. This is not a new Camaro motor. A CAI or exhaust are bolt ons that don't require extra tuning on our motors. The rest should be tuned.

 

100,000+ miles on a tuned car? Surprised of what happened? Sheesh

 

The very best preventive maintenance on a highly modified engine (or any engine) is to spend around $40 for an oil analysis. A regular oil analysis program can inform you of abnormal internal wear, leaky injector or coolant leaks, etc...etc..

This is best done by maintaining a regular oil change interval and using the same lab - as they will keep your records and track the percentage increase in oil contaminants and viscosity breakdown from oil change to oil change. This will warn you of pontential falures and allow you to repair the problem before a catastrophic failure. If they know the engine manufacturer, they can even guide you as to what components are wearing down...

Changing your oil after every race will only mask the problems - it may delay the time to ultimate failure if the oil contaminants are contributing to the cause of the wear. But if you have excessive contaminants in your oil - it's a sign of some other problem that fresh oil and filter won't fix...only mask...

 

Yea I agree what do you expect.

 

If they are not going to change their oil regularly then there is no chance their having the oil analyzed. It's doomed from when they buy the car.

 

Do you have a link or name to a place that provides that service?

 

Even at 50,000 miles on the same oil, an analysis can still tell you what internal components are wearing and leaving deposits in your lubricant.

My A&P mechanic uses Aviation Labritories for the annual inspection on my plane as they specialize in aircraft engines and know the composition off most the overhaul kits...

Blackstone labs is popular because they provide free kits.. you just send them back the oil sample and check... Amsoil does testing.... Just dont use a middleman who collects your sample and sends it off to a different lab...

 

Thanks for the reply, I may try the blackstone test since they seem so reasonable. I'm almost at 140k miles and still running relatively well.

I'm a regular on the mbworld forum and there are some people that are quick to point fingers, but the op of the thread you posted never even accused eurocharged. I think it's because there have been a few cars recently that have blown engines and a lot of them had a eurocharged tune, not saying that they are responsible, but a lot of people believe that they aided in it.

I currently own a 2002 C32 and my dad has an srt6 crossfire. He was looking at getting a bmw z3, but when our neighbor got a crossfire he wanted one too and I found a way to convince him into getting an srt6 because it has the same engine as my car.
