Thoughts? More responsive throttle

[Knuckles]

http://www.ebay.com/itm/261012243272

people on 197/200.net seem to be going giddy for this, was thinking of something like this the other day, but I was told it wasn't a viable option, then this popped up.

Sounds like a bit of a scam at first glance

 

[Knuckles]

Nobody? Chip?

 

[Feates172]

So you apply half throttle, but get nearly full??

If so Id buy one and stick it on the mrs car, she wouldnt know what the f**k is going on lol.

 

[Flat Eric]

Interesting......

 

[Scrooge]

I wouldn't bother, just put your foot down further.

 

[McGherkin]

I always wished it would be harder to balance the throttle through the corners.

Get a Ph.1 if you want a more responsive throttle, get the above if you want a badmanz throttle which you only push down halfway because you don't want to unleash all 400bhp.

 

[Scrooge]

Lol^

 

[Gorms]

Im one of the few members who didnt puke in their pants when they this came up. Im struggling to see how you can justify the £160 price tag for a .400th of a second difference and yet it has no effect on the proformance.

Yeah the throttle at times does seem a little slow but you adjust to it. 3 years of 200 ownership and i dont even notice it anymore.

Placebo effect if you ask me.

isnt there a sensitivity screw on the pedal gubins?

 

[Knuckles]

Recently, I've been moaning about the delay in throttle response, after speaking with chip he said there's no viable way to get a quicker responding throttle... When this popped up it intrigued me.

it is a bit steep for what it claims to do. But if it worked I'd say it could be a good product. The delay in the throttle is so annoying in my car when I'm driving fairly placid. I'd love the same response you get when driving higher in the rev range

 

[McGherkin]

I don't think it'll affect the ECU's response to the throttle input (which, correct me if I'm wrong, causes the delay), from what I can see it just amplifies the throttle position value.

It's not how quickly you can mash the pedal down, it's how long the engine takes to react.

 

[mitch1503]

so basically it just sends a signal as though you've pressed the throttle down abit more than what you have so say 50% may give you 75% instead, b****cks to it you may aswel just put your foot down more

 

[Knuckles]

It's meant to amplify the signal when you're driving slowly/pulling away etc. so it gives more throttle to overcome the 'hesitancy' the cars get when first pulling away

This thing looks to have settings too, so you can have it off, slightly sensitive or full on

 

[Dr HMS Derv Destroyer]

i'd rather put the money into getting a cable throttle of some sort that will work

 

[Knuckles]

Can they be retro fitted?

 

[Flat Eric]

Just floor it. End of

That will no doubt need aftermarket management, can't see standard ecu supporting it.

 

[Dr HMS Derv Destroyer]

im not sure. i would presume the mk3 cup racers would be cable throttle driven.

bit of research needs to be done me thinks !

saying that, its not like the 172/182 were you can switch to cable easy lol

 

[McGherkin]

ITBs?

 

[bright]

Surely you could adjust the pedal map for a more responsive throttle?

My very very limited experience seeing my dads Saab mapped has a mode to add a multiplier to the throttle map comfort, normal and sport. The sport multiplies the percentage by 1.5, meaning at 10% for example he'll get 15% throttle?

Cup racers run different management.

Also the loom will need altering to have some sort of tps an icv, the fbw thottle takes care of all of this. Swapping is not as straight forward as you imagine.

 

[Ed.200]

I would rather have a proper map than this, imho. It may work but being so plug-and-play will it? to pricy to be worth a gamble for me. Although i never really have an issue with the throttle response, just be in the right gear and go.

For ITB, from what I have seen, peopler have the current one bored out from 60mm standard to 63mm or 64mm

 

[not normal dan]

Whats wrong with putting your foot down? Have you tried switching the esp off? My old 197 seemed to be more responsive then if I'm honest, maybe just in me head haha.

As for enlarging you thottle body from what I've read in a recent thread its a waste of time an money, heres the link.
http://www.cliosport.net/forum/show...lio-172-Cup/page2&highlight=clio+197+enlarged
Read page 2, some good info from danny an chip.

 

[Ed.200]

Only seen ITB's mentioned in passing. Just read up some more on 197.net as well. Prices they are mentioning are ridiculous, and the problems list is just as long.

 

[not normal dan]

N/A tuning on the f4r is very expensive for not a very big gain, boosted converisons are usually more expensive (depending how diy it is) but you get more bhp for the money an alot of scope for future tuning.

Thats what I thought. But we'll fin out if it works at the end of the group but on 197.net.

 

[Matt W]

Won't be buying one.

If it's that amazing then Renault would have included it as standard.

 

[Knuckles]

I'm staying optimistic on this one. I'm sure they'll be pants, but since they've won so many over on 197.net I can't help but think there may be something to it

 

[Ed.200]

And the price they may be able to get them for, now almost makes it worth a punt.

Will be interested to see if they yield any results.

Exactly, the inlet is manifold itself is more restrictive. Accordding to "chip" it hits maximun air flow log before maximun thottle angle is achieved. People just assume bigger is better, an because its 200 quid it works! Renault spend millions developing these cars, if a bigger thottle was going to make the care perform much better why didn't they do it?

Has anyone ever hooked up a manometer to various parts of the intake system see where the biggest restriction is? I bet it isn't the thottle body!

How they going to test them?

Yep some kid rubbing his hands after a bit of cnc machining on a saturday morning haha

It's an electronic device you plug into your throttle pedal iirc.

 

[Ed.200]

From the website - http://www.sprintboostersales.com/whyitworks.cfm

Matt is correct. They plug into the throttle pedal, and increases the response time.

I was reffering to the thottle bodies

 

[scotty2hotty81]

Sprint booster have been around for a while now, loads get fitted to Mercedes to try and reduce the delay when pulling off "a bit eager"
Basically all it does is make you throttle more sensitive.

I'm not saying your wrong that the manifold is the restriction but an enlarged throttle body will give a harsher throttle and could be a benefit for out on track IMO when mapped. The reason Renault never done it as standard is the same as every other manufacturer and that's to not undercut higher spec models as in Megane.

You will notice that most manufacturers match power within say 5% of the equivalent car that the competitor is selling. They keep their cards close to their chest and slowly drip feed power and suspension updates to the public. If they went all out they would have no where to go next car. Obviously there is advancements in technology but IMO the 197/200 f4r could have easily came out with 220bhp if they wanted to.

 

[Gorms]

Of course they will say its amazing! They have just thrown £150+ at it.

I was confused there, I thought that was a dig at me wanting to make spacers lol (I've put a few threads up about them)

flol! Good point

Oh no doubt, you won't have to open the thottle as much as it will flow more air due to the enlargement but they'll be a point when the engine meets its maximum airflow capabilities due to another factor, an that will be before the thottle is at maximum angle, so why make it bigger? Just be quicker on the gas

Personally I'd rather spend the money on a set of decent brakes or towards some decent tyres that'll no doubt have a bigger improvement in lap times then an enlarged thottle.
