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?

 

[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.

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.

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

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

 

[katy81]

This is a bait post isn't it?

Your really going to argue over a factory stated 30hp?

The 0-60 times are literally within 1 second of each other

 

[katy81]

How are you only getting 200 miles out of a tank in the ST220?

That's about 15mpg, is it broken?

It says 220 (ironic) range out of a full tank.

Mostly says 19 mpg around town and about 33 on a run.

 

[katy81]

No that's about right round town.

I had the st200, around town i would get 18mpg, on a run though could get 38mpg.

The 220 has a whole 0.5 more displacement.
Lovely car for what it is. Much better than a similar era BMW.
