The AFR is still very rich and that's not the only aspect changed.

We run less ignition timing targets and this brings down the EGT's. It is EGT's that burn out valves.

Stock Euro E46 M3's run...

Very nice. I hope more datalogging is performed on these engines!

Of course the IAT will always be incredibly stable on an NA car with such a brilliant intake system.

Your ignition timing is...

Look very much forward to hearing from you!

This could be nothing to do with the BOV. It could be be related to how the DME has been calibrated. Who knows?
I doubt that BOV is the cause having seen it being used on other kits. It is a very...

what about cylinder heads?

and just to add to that,

We all know what stock cars do on a dynojet on average. 430-440 approx. Talking about S85 here just to make clear.

Dinan engine comes along quoted at 611 HP according...

Now you know what a graph looks like where the engine is really making an extra 80hp over a stock motor and it's flywheel calculated.

Now, someone care to draw a graph to show what the graph of a...

Your dyno comarisons are kind of going in the same break away from the original..... and it's about to get way more entertaining in your case!

Indeed.

And you can clearly see from the graph how safe I tuned this one and still made +80hp.

OK cool, I was getting paranoid there!

I think you are confusing this with wheel HP somehow.

This is not a 700rwhp suggestion by Dinan, it's crank HP. It's on an engine dyno which is measuring crank HP as it's attached to the crank.
...

Here's another one for you guys from our dyno:

Flywheel calculations but you get the point. ...

If that is happening, the plenum would blow. If it's too strong the excess charge would blow by the impeller in the supercharger.

The throttle bodies would be closed in any case and there is no...

:)

Soon....

This thread gives us, somehow, some motivation. I cannot think of why !

92 only difference is the larger intake but this has no effect at all and was only done where larger intake sizes were being used.

Tried using that already, did nothing.

You will see a different power curve to what you may think. I am confident in saying we are very good at maximising the efficiency of the setup especially at the higher rpm's :)
We will probably...

Got some time finally to post. Currently in Finland on work. Cold here!

For us atleast this is not the first time we have seen such information but never on a public forum. Without sounding...

Talking about S54 Superchargers - well... we will make one now. It was already in development some time ago but we dropped it because other stuff was going on.

As for the subject of this thread,...

Thanks Benzy.

Just a small correction - S62 Supercharger kit is in production for some time now and running successfully on cars.

Actually no. He knows we are perfectly capable of the tuning ourselves as we do alphaN on NA cars like the E39 M5, E60 M5 and E46 M3 way before any of this started. Then he also knows that if you...

I should put up the images of the one we are installing here right now.

ok,

some interesting questions coming through from some people.

Can we use a charge cooler instead in our plenum?

Answer - yes we can, very easy. All we need to do is make a new base plate...

Absolute zero slip issues.

However, with an 8 rib setup... belt slip is absolutely minimal anyway.

It's released.

From the initial response, looks like more european customers want this kit. All but one of the first 10 have been sold in Europe who are just waiting for delivery.

list of main parts in image:


1 x Crank Pulley (8 Rib conversion)
1 x Water Pump Pulley (8 Rib conversion)
1 x Alternator Pulley (8 Rib Conversion)
1 x Tensioner bracket with wider idler...
