I have had this supercharger for almost 6 years now!!! it is an rmm kit that was custom retrofitted for a gs430. I am yet to see another one like it. I actually finally have my tuning appointment set for next Wednesday. I should be around 400whp. But I will be tuning on a dynodynamics (heartbreaker) which is one of the best dynos with which to tune a car, only problem is they read very low (hence the heartbreaker) but maybe after its tuned I will run a dyno on a dynojet or mustang dyno (those are known to show up to 20% more power on paper. But I guess what really matters is the way she drives so I will provide more updates this coming week.

So I got my car tuned but there was a boost leak so I had to cancel the tune midway (as I was getting charged by the hour). Well went home tightened all of the couplings on the piping and removed a vacuum hose that was going from the throttle body to the air filter. It was just robbing boost. So now car is running great. Though I still need a proper tune. But I have no cel lights and car is pulling stronger than ever.

I made a video earlier, but it's kind of hard to get good runs in with all the traffic where I live and all while holding my blackberry to record it, that plus massive wheel spin and looking out for cops is a big no no.

But here is a video 0-60

I had wheelspin right away so I had to let off the gas to grip. Also I didn't power brake at all. just stepped on the gas. Correct me if i'm wrong, but i went over the video on my video editing program and the speedo starts to move at 1.65 seconds, and i hit 60 at 6.49 seconds = 4.84 0-60 

Maybe someone else can double check that for me. Either way its a fast 0-60 for having had so much wheel spin and letting of the gas in between shifts. Here ya go!!!

I havent decided on prices yet, but I would think the sc unit will be in the 5k range. This is the ONLY rmm kit that I have ever seen that has been modified to fit the 430 engines. I also had to have a few more parts custom made and added a few accessories to the sc kit since I purchased it to make it work and to make sure it is completely plug and play. (no splicing injector wires, and interceptor will come with a custom tune making the car completely driveable with the larger injectors , though a fine tune would still be a good idea to maximize power but it could be done in under an hour since I already have base tuned maps, therfore tuning should be at most an hour on a dyno basically $150 or less)

I am going to sell to the person with the highest offer seeing as how rare this kit is and all the money that has gone into it to make it work properly.

Also I need as much as I can get to move onto my next project. But I think the 5k range is good specially since the car can be daily driven and be pushing close to 400hp at the wheels (could be more or less depending on exhaust, headers, pulley size. 

Oh yeah also kit will include 2 pulleys. 

I am also getting interest from ls430 members seeing as how this kit should work with any 430 engine. Though a few pieces of the intercooler piping might need to be modified to work with other 430 model lexus'

I will post prices when I get back from boston next week.

I actually installed it at the end of august. And I have had a street tune (no dyno) which is why it runs good now and not running rich or any type of cel light. The car drives good (which you should be able to tell from my 0-60 video) but I am selling because I am going to upgrade to a new car, new project. I thought I would keep the gs430 forever but after riding in one of my friends cars I want to upgrade. it's a bit pricier than my gs so that is why I have to sell off my parts and car to save up as much money as I can get. 

And I actually might be getting it fine tuned next week seeing as how it shouldnt take much more than an hour to tune now that there is a good base map to start with. Also it seems that their is always a lot of talk about people wanting superchargers for their gs' but then it takes a while to actually get sold. So I still want to be able to enjoy it in the mean time, and I can uninstall the entire charger in one day, so I will remove it the moment it sells, that way any locals can also ride in my car if they are interested in purchasing it.
