Egil,
Thanks for the info. I was afraid you'd say that. Now my quest for a 6 speed M70!!!

Well, how is your trip to DC coming along. Inquiring minds want to know....

Peace!

since there are 1200 M73's made I would not get my hopes up.
Johns kit is for the M70 only.
The M73 is quite different, it has a higher compression ratio which means it cannot be supercharged without some internal work.
You may be able to get a small supercharger, but you would be limited to 4-6pi pressure, and you would be lucky to get 400hp in the end.
The M70 has a compression ratio of 8.8:1 which is perfect for forced induction.
The M73 and S70 is around 10:1, charge to much and you will blow gaskets.
it can be done, but without lowering the compression ratio no huge power gain is possible.

Thank you! I just sent John an email.

Are you aware of anyone on this board who installed a supercharger on their M73? I'm hoping it has been or can be done.

Peace!

Noggie,

Congratulations on the Supercharger. I look forward to hearing about the results gain on your E31.

Do you have the contact information for the person you bought the SC kit from? I'm very interested with some specific questions.

Thanks!

When I first drive the car I get a dull shuddering/vibration apparent when I apply the throttle, it diminishes when I back off the throttle and disappears when I get past 1500/2000 revs or when the car is warmed up. I suspect the propshaft rubber thrust ring - has anyone had this problem?

Does it sound anything like this

I can vision that with a bit more flair extending rearward....

Peace!

Looking good although I think it may look better curved on the ends rather than angular as the rest of the rear of the car is curved.

if you could run the curve parallel to the roof line it would be perfect.

Carry on.

Depending on the mileage of the engine (let's say its 50k or more miles), I'd do (and have done on my car) the following:

1. Put "Motor Clean" (http://www.liquimoly-direct.co.uk/userimages/procart6.htm) in the engine oil. Run the car for like 15 minutes and flush all old oil out (remember to run the engine hot before the drain).
2. Put new, full synthetic oil in there. Your pick.

You'll be fine as the change from mineral to synthetic is nothing major at all. It's an "upgrade", anyway. Just remember to use thicker oil grades.

IMO- Unless you race or drive your 850 hard on the autoban, anything over 40w is overkill. You don't need that thick of an oil. Especially with sythetics. I run Moble 1 10w40 during the warmer months and 5w30 during winter.

Magnaflows with straight pipes from the Cats back to the cans. Center resonator delete.

I love it! Car is quiet until stomped on hard. No droning, too.

That's it! Very nice sound. Here is one on a V12 w/o the resonator.

Hi Everone,

Just revisiting some past post regarding exhaust/mufflers. I found it to be helpful for those that are looking replace their stock setup. Mine are starting to show some rust holes for its age so I just thought I would throw it out there. Anyone care to share their setup?

Noggie,

Welcome back!!! All in all being on the road with your favorite 8 after being gone is well worth the effort.

Thanks for sharing your day

Hi

...and even better in person!!! And your car looks fantastic as well.

I hope you guy's made it safely through the pass coming back from the 10th ARRWBTT in Santa Rosa, California. I enjoyed meeting everyone!

Very nice!!! I would love to do something simlar.

Why not use the passing lights as such? Anyone done this? Any warning lights.

Looks like a great meeting in sunny California!

I had a great time! I met a lot of people and made some new friends. Thanks to Dan, Peter and Steve for organizing it. I'm looking forward to the Central Coast Wine run. I hope soon.
