I just finished installing our new power pulley for the range rover sport superchared its night and day difference on power

The car is much quicker off of launch and went doing full throttle the truck keeps pulling like an ape. the entire power band is just so different
in park hitting the pedal the engine spins quickly without hesitation at part throttle its amazing car just pulls so agressively. It has increased throttle response by more than 20%


All we need to do is finish up the software and really add some aggression 2006 Range Rover Sport Supercharged Speedinnovation Custom upgraded supercharger pulley,exhaust, tv mod,smoked lights, smoked side markers, 23" rinspeed wheels, 315 tires all the way around, arden kit

nice...were you able to get a baseline of your RRS before you did this? I'd be curious to see how much of a gain you got.

and i like the analogy of "pulls like an ape" my buddy once called his home brew of race fuel and how his car reacted to this concoction as "it drove like a raped ape" www.vip-culture.com | 06 RRS HSE | 06 Odyssey Touring

nice!
what size underdrive pulley are you using? are you planning on dyno'ing it soon?
keep us updated, plz

Right now we are trying to finish up the software so we can do a dyno another issue is that we need a dynapack or a 4 wheel dyno as the rrs is all wheel drive do you guys know if we can unlock so its only rear wheel drive I have tried to figure this out on the 4x4 screen but cant get it to work


Yea we made the pulley as small as possible the supercharger is running 12.5 psi now!!!

pulls like an ape seriously not kidding took it out again this weekend and a 350z thought he was going to get to cut me off as we were at a signal I took off on the green and left him as he tried to pull off the green light as well but he quickly realized that he hade no chance at getting in front...

hahhahahha

we will see how testing goes this week as its supposed to rain and we have alot of cars that we need to finish custom software on 2006 Range Rover Sport Supercharged Speedinnovation Custom upgraded supercharger pulley,exhaust, tv mod,smoked lights, smoked side markers, 23" rinspeed wheels, 315 tires all the way around, arden kit

It's full time AWD and you have no manual control... you can't make it rear wheel only. It does frighten me a bit you are working on this car, including "custom software", and you don't know that.

Please post real numbers when you get them.

I also see you posted this thread in the Europe specifc forum? Now I'm very confused... [now moved by moderator - yay]

Whats the details on the pulley and the install? Did you use a pulley removal tool? or just wrench it? Also post some pics of your 23's please. I would love to see how the fitment is. Thanks!

I am surprised you have found such an improvement although we have gone a slightly different route to produce 14 psi the actual bhp gain is only about 35bhp ( we had it on 4 wheel dyno as standard and with changes). We are busy on the rolling road with the programming - then there will be a big difference.

theres a suprise nothing good to say but question others at least they are not afraid to come on here as who they are ie names and profiles etc so whos the royal WE or is it a bit secret squriell orare you just a a wanabe teaboy come on come clean

I hope that you price it well, my pulley is inexpensive:

My Pulley is also the smallest that you can go, since the Blower housing goes inside the pulley. B.T.W. Eurotoys was the first Company to have this small upper pulley for the Jaguar 4.0L, then the Jaguar 4.2L and now the RR & RRS.

I have noticed that their is a kit on Ebay that includes a Tensioner, Belt, Remover tool, Installer tool for about 2.3K USD. All of that is alot of stuff that you do not need and for a lot of money.

Well this one is for grommet why would it scare you that we are doing custom software for RRS

Why wouldnt we www.speedinnovation.com

We are hardware and software engineers
"SpeedInnovation" hence the name


I cant tell you exactly what we are doing but there is an extent where you cannot make the upper pulley any smaller without turning down the eatons nose ( we wouldnt do that anyway ) however we have found another way to add plenty of boost but we are currently designing a few new parts that are key to longevity and plenty of fun 2006 Range Rover Sport Supercharged Speedinnovation Custom upgraded supercharger pulley,exhaust, tv mod,smoked lights, smoked side markers, 23" rinspeed wheels, 315 tires all the way around, arden kit

as far as eurotoys you can take the advice either way but hopefully you take it positive. I know all about your hardware


business out there sell products for example

honda civic 20,000 new

Range Rover Sport Supercharged 76,000 new

theres a big difference in price but theres one that has obviously better quality and engineering in it

so honestly guys would you risk the engineering for the price or would you sacrifice price for engineering on your 76,000 RRS

Thats the response I give you regarding your pulley

and as a last note we didnt claim to be the first to make a pulley for the RRS we make the second pulley but better  2006 Range Rover Sport Supercharged Speedinnovation Custom upgraded supercharger pulley,exhaust, tv mod,smoked lights, smoked side markers, 23" rinspeed wheels, 315 tires all the way around, arden kit

It does not really matter to me what the RRS costs, in the end the Upgrade is just a small Steel Pulley. Not much to make different unless you make it out of Titanium.
