electric superchargers will help but you need an SAFC-II if you are going to use them properly...

an SAFC is just an air to fuel ration controller... basicly it just monitors your air to fuel ration so that it stays aroun 14 percent... and sence the electric super charger is going to boost the intake with more air... then you are going to need more fuel... so the controllor will help with that up to a certian point...

they can be pretty pricey too...

now if you can just get a K and N intake kit for your car... you can get a good 10 percent increase...

now as for using the super charger out of another vehicle... i am not sure what kind of super charger the range rovers use... but seeing as they are a v8 motor... its probably a top mount super charger...

which means that it probably connects straight to the trottle body... unless its a side mount super charger i dont see it being any good for what you want...

i would have to explain this in person seeing as the internet doesnt allow me to really describe this in words like i need ...

most super chargers just bolt up with an extra pulley and you might need a longer belt... some have extra belts with the kits...

again if you increase your air intake... you need something other than the stock O2 sensors to control your fuel ration so i would recomend an SAFC...

but they are not necessary... but they help...

if you would like this saturday i am off... and i have nothing to do... other than clean house...

me you and some other car people can get together and talk cars... maybe just hang out... or if some one has something they would like to do to there car we can all work on it... i miss working on cars hahahahaha

what do you think darude... would you like to get together too... and talk about cars...

oh and i can take some pretty good pictures with cars...
