How many psi would that 74mm make you think?

close to 14 to 15 psi

Looped rail and what other stuff do you recommend?

I have split cooling/HE and soon to be new fuel stuff.

fueling / cooling mods and a good tune

So if 89mm is stock size no tune is needed correct?

2000UZJ

You will need a tune in order to run a fixed supercharger pulley. Stock size or not.

03svtkiller

That doesn't make sense if it's stock size, only advantage to the fixed will be the loss of harsh clutch bucking engagement, I'll text Shardul right now and get the answer.

I think the tune would mainly be to help to computer forget about the clutch missing and throwing a error code. But i could be wrong.

03svtkiller

You are correct sir it would be just a flash so it can adapt to new settings.

But no actual tunning is required for stock size.

2000UZJ

What is the difference between a flash and a tune? You asked about a tune...then stated nothing is needed but a flash.

03svtkiller

That means it only needs to get flashed for the clutchless pulley, as in no boost increase or any additions to that but rather just to adapt settings for the "fixed" pulley.

Other sizes are different. For stock it's only a flash from clutch to clutchless viola

It gets rid of the clutch engagement and weighs a good deal less than the stock pulley (rotating mass at that). Power is instant with the fixed pulley and is awesome. Since you need a tune with it (a.k.a "flash"), you pick up a bunch of power. It's awesome. And when I say "instant", I really mean it. It's crazy awesome.

I get the instant boost I'm more looking at the stock size not to increase boost but just to get rid of the clutch engagement but a lot of people are still having issues with fixed ones

As my DD I am still a bit worried about the bugs. I am leaning towards the clutched pulley but I do love the idea of the fixed.

Sir what wheels are those on that black e55.

Just curious, the "74mm pulley" is equivalent to what size C/P. Thanks.

03svtkiller

Will be equal to a 185mm CP.

1. To which of these pulleys will not require a cooling kit?
2. What if you have an headers, will it make a difference with the cooling system for any of these pulleys, and which one?
3. Does that mean that the only difference in the stock fixed and clutched pulley, is getting rid of the clutch engagement and no power gain?

Please need honest responses. Thanks!

Your area under the curve (which usually the E55 doesn't need help with) will be improved since boost hits so fast with the FSP. But no, theoretically there will be no gain with the stock sized 89mm FSP

Headers will make a difference however YMMV type situation. You will be in some amount of boost as long as the car is running. With the FSP there is hardly a time you will be in vacuum. So there will be more heat produced. The extra heat shouldn't be much of an issue with the stock 89mm but like I said YMMV with location and weather

It sounds too simplified if you say only gets rid of clutch engagement. Its much more than that on the whole feel. The car suddenly feels half its weight and throttle response is seriously improved. yet it is smoother and feels like a well tuned NA engine (Aka BMW but more crisp)

just placed my order for an 89mm.... can't wait to try it out!
