How to add more Hp to a 4.8i?
 

I would like to add at least 40 more hp if its some how possible and torque. Any ideas how? safe way :D

Forced induction, likely a supercharger, from one of the tuners. G Power claim +95 hp on that engine with their stage 1 kit, and go up from there. No comment on how safe it is, you'd have to ask someone who owns one.

I am thinking of buying the Supercharger System SK I, I sent them an email about the product. Does anybody know how I can get the price for that? it doesnt show in their website.

Look at this web site. It's $22K for that supercharger....

More power, reliability, low cost. Pick any two.

$22k ??? wow I thought it would be around 3-4k

Yes, I thought you might be (unpleasantly) surprised... I had the info handy because I'd previously tried to find any options for a hp and/or torque increase for the 4.8i.

Well, I guess I will have to take 4-5 months of work to save some cash lol.

Take the $22k + current X5 and make it into the X5M :thumbup:

Thank you noodle, I was thinking the same thing.
