Supercharger upgrade

[katy81]

Got a 2.3 clk bit slow.

It's like every other forced induction car. Nothing for ages and then it finally starts to go.

I've heard their are two options larger crank or smaller sc pully.

What are the benefits and negatives?

Surely a crank would cause all accessories on the belt to run faster? Potentially damaging say the alternator?

I've heard their are three options larger crank or smaller sc pully or buy a different car.

Fixed.

 

[katy81]

Fixed.

Yes but for £500 quid I couldn't say no and was fed up of driving the anemic 3 litre fwd st220 about

Is this the car thats in limp mode with a failed mot and an el cheapo cat off?

Failed on lights, limp mode was a dirty maf. Cats still there. Was going to decat the 220 because it doesn't sound very good with the standard exhaust

Sounds like a dream car

Which one? They are both good cars.

Clk was only on 90k miles, did 13k miles in its first 10 years.

Not like every other forced induction car. I had a supercharged SLK, it had all the torks from 1000rpm upwards. No lag at all.
There's something wrong with yours I think, since if I remember correctly the SC on that is always engaged? On my SLK the SC had a clutch and it only kicked in when it was required - and still, zero lag.

A larger crank pulley will cause accessories to turn faster, yes, but unlikely to damage anything.

The main plus of supercharging over turbos is that the power is there all the way across the rev range due to not having to wait for exhaust pressure to spool the turbo up.
Sounds like yours is broken.

As mentioned, a supercharged engine is always on boost. Or at least should be.

I think that these mercs have the kompressor supercharger, so that's a good starting point to investigate.

Bypass valve on the left was sticky. Freed it up. Closes the second throttle is applied now. And it closes properly

I'll see how it is on the way home.

**** it, stick a Whipple twin-scroll on that shed anyway.

He Bypassed the reply.

Because 190hp in the heavy CLK body offers so much more performance than an ST220?

 

[Diddums]

Yank the cat, +50hp and it'll sound well wikkid bruv.

Why do any of you reply to her, have you ever thought that if everyone ignores her she might take the hint and **** off

Would that work for you?

It literally offers the same performance. No where near as fun going round corners but acceleration is pretty much the same and that's with the autobox too.

And it gets like 300 miles to a tank compared to 200

 

[Kenai]

It literally offers the same performance.

This is a bait post isn't it?
