hey there bartkat, what a coincidence! I was just over at another thread looking into some power mod applications. You posted a web link to a Lexus performance shop that puts turbo and supercharger packages together. You posted the link like a year ago. Link still works for the info!!
So after looking into it I have decided to go Forced induction after all.
Yeah, I've searched the web up and down to find out all the performance gains and pros and cons of each. There are some interesting combinations out there, but for the money, sure seems like alot and a crapton of work for so little. So, rather thatn waste my time and my money, I just tonight decided that I will return the Typhoon by K&N. I'll skip doing the ICU Programmers or a piggyback power chip of some kind, and go with the Raptor V supercharger.
My IS is an everyday driver. So I don't want to mod it to race only settings. I figure if I can get between 300-350 hp, I'll be happy. I was going to look into headers and exhaust, but I really like the quiet of stock, so I'm not really sure what I'm going to do there. Also I want to put anti sway bars on to help stablize things. Maybe upgrade shocks and springs if I need to.
Right now I'm in the planning stage of all this, I want to have a definate starting point and a finish point. Even if I decide to add or change things later, I atleast want finish one thing at a time. Heck the halo's for the headlights aren't even here yet!
So, I figure it will take about four weeks for them to build the supercharger and assemble all the parts for the system. ( Piping, blow off valve, oil cooler / intercooler, etc.etc.) I figure less than five grand will cover it. And I will get to 300 hp atleast for sure with no problem!
