Guest Posted February 22, 2022 Report Share Posted February 22, 2022 ...surprised nobody has mentioned sprint booster also has a pedal lock system that essentially works as an immobilizer with a 4 digit code...? Handy tool if car parked up for any length of time..... or out of town . Quote Link to comment Share on other sites More sharing options...

Simon_R Posted February 24, 2022 Report Share Posted February 24, 2022 (edited) Does it tuck away behind the pedal ok? Does look a great mod for the £ Edited February 24, 2022 by Simon_R Quote Link to comment Share on other sites More sharing options...
Guest Posted February 24, 2022 Report Share Posted February 24, 2022 (edited) Can't see it at all from the pedal....all you see is the control " handset " controller. Mine's mounted to the left of the steering wheel. Edited February 24, 2022 by skoosh1970 Quote Link to comment Share on other sites More sharing options...
944GS Posted February 24, 2022 Report Share Posted February 24, 2022 (edited) I’ve never heard of this until I read about it here but have just ordered one as it sounds like exactly the kind of modification my car needs. One of the only things I still miss from my Golf r is sport mode, sounds like good value for my £187, hope I’m not disappointed but looking forward to trying it especially as it’s something I can actually fit myself!

funbobby Posted February 24, 2022 Report Share Posted February 24, 2022 The people that have them fitted did you bother telling the insurance company given they have no actual power change ? Quote Link to comment Share on other sites More sharing options...

Don’t have a dog in this fight but I doubt that anyone would “win” the argument with an insurance company - When they say “ red cars crash more often”. they will be racing to the bottom line of “ undeclared modification “ if they can swerve liability. They are not (despite their marketing) doing us a favour. Quote Link to comment Share on other sites More sharing options...

Ninesomething Posted February 25, 2022 Report Share Posted February 25, 2022 I think yes but there's a bit more to it than that. They also speed up the responses in the ECU. The effect is sort of faster pedal with quicker responses to what the pedal is saying. Do you have sports chrono? A bit like that but customisable. And cheaper - but of course it only interacts with the throttle. Quote Link to comment Share on other sites More sharing options...
Menoporsche Posted February 25, 2022 Report Share Posted February 25, 2022 I do have it, which is why I ask. There are those who don’t like it as shorter pedal travel makes it more difficult to be precise with throttle input. If the software reacts faster then great.

Ninesomething Posted February 25, 2022 Report Share Posted February 25, 2022 Spose it depends on how your sports setting compares to the available options on the SB. Most people seem to think that setting sport 5 is the best option. IIRC correctly can you not set it how you want then remove the controller bit leaving the rest active?

944GS Posted February 25, 2022 Report Share Posted February 25, 2022 My sprint booster arrived today and I’ve just fitted it, settled on the Sport 7 setting for now and although I’ve only had a short drive to try it out I absolutely love the difference so far. I bought from Rtec Auto Design as they were £30 cheaper than Design911 even after using the 5% discount code. 1 Quote Link to comment Share on other sites More sharing options...

funbobby Posted February 25, 2022 Report Share Posted February 25, 2022 For the life of me I can’t see how to disconnect the throttle connection ? Hardly seem to have any wire spare and can’t get my hand round the back of the pedal to grab anything?! Quote Link to comment Share on other sites More sharing options...

I removed that screw you can see and took the pedal off so I could see the back of it. 1 Quote Link to comment Share on other sites More sharing options...

Not quite decided yet @BBB so I've run the cable under the carpet behind the pedals and round to the centre console then through the removable side panel to the front for now but not stuck it on yet.

The effect is sort of faster pedal with quicker responses to what the pedal is saying. There is no more to it than shortening the accelerator pedal travel. It can adjust the gain to give 100% throttle output over 30%, 40%, 50% etc of pedal travel in a vast range of "performance enhancing modes" (or giving 30% output @ 100% throttle in valet mode, 0% in lock mode etc etc). but that's ALL it can do. If you like this effect then go for it but it doesn't "sharpen" throttle response and the ECU will process the throttle signal in exactly the same way as it does without this device. 1 Quote Link to comment Share on other sites More sharing options...

944GS Posted February 26, 2022 Report Share Posted February 26, 2022 Just back from my first proper drive since fitting yesterday, 50+ miles on mostly fast A roads and I absolutely loved the difference. I know the car isn’t any faster but it certainly feels it and made me smile, that was on the Sport 8 setting. 1 Quote Link to comment Share on other sites More sharing options...

Given that it sits in the signal path from the accelerator pedal to the ECU then this is all it can do. It can't modify any other aspect of the car's behaviour. It's like wearing lead wellies when you drive the car. It magnifies small throttle inputs so they become big ones. This will take delicacy out of the driving, particularly noticeable when manoeuvring or driving in traffic, but will make the power more accessible when only pushing the pedal gently. It's very like the throttle cams that people used to fit on their 944's; people would fit them and report huge improvements in the way the car responds, as if it suddenly has gained a lot more power. However many people decided over a period of time that the pedal calibration from the factory was indeed better in the real world and took the cam off, replacing it with the standard one (if they had the good sense to keep it.) As with all things in life, you pays your money and you takes your choice. 1 Quote Link to comment Share on other sites More sharing options...

As with all things in life, you pays your money and you takes your choice. One interesting feature is the selection for use with manual or auto gearbox. Presumably if you run it in manual mode response input/output is totally linear, giving 100% output at partial pedal travel. If you select manual mode with an auto box, does it trigger kick-down at part pedal travel? In auto mode, linear i/o to 90% then delay the last 10% until the pedal is near fully depressed so kick-down is delayed until the pedal is fully depressed? Has anyone tried this? It could do other fancy things like momentarily producing say 80% output on any increasing pedal travel to make response feel more peppy. Who knows? There must be a website somewhere that has analysed exactly what this does. There would have been R&D costs involved, presumably an ASIC but £180?
