Roady with Performance Clutch and Charge Cooler

Re: Roady with Performance Clutch and Charge Cooler

But k_o your 0-60 times are only that low as you dont have the crippling gear chage at 58mph. Because you can rev over 6200 you can just eak out that last few mph before that change.. anyone can achive that with a remap.. the truth is my 1.5d megane is quciker 0-60 than the roadster but never feels like it as my derier (a$$) is closer to the road in the roady

That's what I meant. The gearchange can be improved.
And to all, the times weren't the best posible. I missed the change in one gear in echa try but wouldn't continue doing it just because I was afraid of wearing the clutch too much.
they can be much much better.

And, each to their own. I find it expensive too. I now focus on other things than powern like handling or stopping which give you greater advantage than power unless on a drag race or the motroway(two things I don't like to do)
SO for me it was the need of the power to handle the car right on a curve and I'm well pleased, I never felt the roadie needs more. BUT I'd love much more power just for the thrill of getting at bigger machines that just destroy every effort you've made on the bends in a straight line in the circuit. It's just not fair...:wag:

Re: Roady with Performance Clutch and Charge Cooler

Seen all this talk about quicker changes by changing JUST the clutch....WTF.
Please explain HOW that works!!!!!!
Also , why after having the clutch fitted do you then have to go to a smart/Mercedes dealer to adjust the clutch electronically at more cost?

Re: Roady with Performance Clutch and Charge Cooler

In terms of cost benefit analysis - if someone came up with a quick box for the smart - I would get that. You'd get better acceleration through the gears permanently and that and a remap/better induction is all that a smart needs to get some real performance.

The current box is ****, always will be!

If one uses the same cost/benefit analysis on performance - you would be looking at buying a 'proper' car with 'proper' performance in the first place.

Ian, it is not just the clutch, its the whole assembly.

Explain? You of all people should understand.

Coo chill out dudes! smart beat may turn into smart punch up.

Right I am of to open a bottle of red!

Explane? You of all people should understand.

but it is still controlled by the same computer program as the old clutch - with the same gearbox! I know the benefits of the lightened flywheel but the clutch - that I am going to buy at some point - is still controlled by the same software. I can again understand that it is faster (marginally) than the normal clutch but not as much as a quick box (if such a thing can be engineered) and new software would make it.

In the Berkeley world, as spares dried up, everyone realised that the chassis was fantastic and could handle more power which is why there are mini, renault, triumph bike engined, etc berkeleys about. My Berkeley has 75bhp approx with a 363kg all-up weight. So go work out that bhp per ton and go weep when you discover my 1959 normally aspirated car can beat yours for that honour.

If you want performance and a wolf in sheep's clothing get a Bond 875 with an Imp Sport engine - it will wipe the pants off even a 120bhp Smart Brabus in a straight line to well over 100mph. Shame about the corners though!

Re: Roady with Performance Clutch and Charge Cooler

Chill, if I wanted any of the options you offer I would be doing it. My point is that the smart is my chosen car and I will do what I want to it. Regardless of what is better, faster, lighter etc. the smart is what I enjoy.

You do not have to justify your opinion to me. You are welcome to disagree and have your own views.

As for the speed of the clutch, well, nothing is perfect but this gets very close.

Re: Roady with Performance Clutch and Charge Cooler

My thoughts are that it wont speed up the *actual* gear change per-se, but it will lift the clutch up, and 'snap' it close quicker, so reduce the overall gear changing process.
Unless you play with the drums which change the gears themselves, the time in the physical act of the gears changing will not alter.

thats what I think anyway

brrrrrrrrrrrrrrrrr

it's kinda cold just now!

Nice to have some debate here. What you must remember is that I'm not disputing the benefits of the clutch or chargecooler, just that there are better things to spend my money on (until my car needs a new clutch and then I'll be getting a bonalume clutch or even the better one that may come along in the meantime).

Massive, we at least agree on something. :silvertri are great!

And if all the mods cost less than a grand all in, we'd all have them - but they don't. I'm not after the next big thing - just a comfortable, fast and stylish car to get me from a to b or sometimes just from a to a! And I'm lucky enough to have more than one car to choose from.

Out and about tomorrow - Wellsmart, Poole then home - roof off all the way:p

Re: Roady with Performance Clutch and Charge Cooler

Intrestingly I am suprised no one has come up with a way of cooling the throttle body and air inlet manifold!

Smart-related friend of mine has a Aquamist water/alcohol injection system installed in his 4/2. It's Dutch, but I think you can make sense of it only just If anyone needs translation, let me know. I don't think any smart 4/2 nor roadster has been modified like this on the standard engine as this one:

P.S. That's 104 hp on the wheels, not the flywheel, by the way.

Re: Roady with Performance Clutch and Charge Cooler

I know a guy over here with a 4-2 which is 140+hp,

very very fast indeed! gulp, is having me roadie for breakfast :redface:

My Roadster has water/methanol injection, water sprayers on the Intercooler and Forced Fan Intercooling. I did this some months ago! See here:

Plus more recently uprated the fueling supply with a rising rate fuel regulator and gauge. see here:

I understand this perfectly which is WHY I want you or Paul Murphy to explain HOW changing a clutch and flywheel will speed up a gear change. Even Bonalume(who I was the UK distributor for) say it is a STRONGER clutch.

but it is still controlled by the same computer program as the old clutch - with the same gearbox!

says Campbell McC

Therefore it CANNOT be quicker!

Tilton make a clutch plate that fits the smart. It is a stronger plate NOT a quick clutch.

Physically a flywheel and clutch assy CANNOT make your gearchange quicker.
A lighter flywheel,which one is it BTW alloy or steel?,will allow the car to produce less TORQUE but allow the revs to rise and fall more quickly....thats IT nothing more.

I am sure that there are some people that doubt this, so go get in touch with clutch manufacturers and ask then if their latest supa doopa clutch plate will allow for faster gear changes.


Just as a side issue, the nitrous set up we put in a friends car works perfectly.Intercooler is also cooled by nitrous. Photos have already been seen by a select few.....:star:

Re: Roady with Performance Clutch and Charge Cooler

To whoever it is going on about a track and a Smart Roadster of any origin - you'll be wiped by anything with a manual box and decent handling - 1st Gen Elises can be had for Roadster money, and if you're shrewd, Toyota engine'd models too for the price of a new'un, and both of those will walk all over the Roadster on a track.

Overtaking in a Smart is downright awful, no matter how much you throw at it. I'm running 120bhp, 105lb/ft torque, and that's not enough to overcome the appalling changes.

I am also with Big - the clutch won't do jaff to the gear changes, in fact, I'd be as bold as to say I'd want a heavier flywheel as the amount of time the car stays off the power changing gear, the lighter flywheel is more prone to spinning down so I'd suggest there is a fine line to tread there as to whether acceleration is going to sacrifice straight line speed because of gear-change deceleration!
