Oooo, 100mph trap speeds are all good! I too doubt they will fit a blower under a stock hood. The intake manifold sets too high already. A cowl hood would look very aggressive on the SC400 IMO, and the car would still look classy. Lumps in the hood are just obscene, especially for the SC.

I think they would use Eaton MP112 supercharger. MP112 (4th generation) is being used by 2003 SVT Cobra. M112 is being used by the Ford F-150 Lightning. The only different between the two is inlet opening. M112 open on the top and MP112 open in the back. In order to save height space, MP112 would be perfect.
Currently, the 2003 Cobra with MP112 with pulley change, exhaust and chip is pumping 498 rwhp. The new Muscle Mustang and Fast Ford Magazine. (MMFF). clocked the minor mods with 11.98 at 1/4 (this MMFF cobra only 465 rwhp with slick).
Anyway, MP112 have a lot of potential. The number 112 mean an additional 112 cu inch to the engine. If the SC400 have 240 (i think), therefore with MP112 it will be 352 cubic inch. The is about 5.8 liter.
With gaskets and head bolts change (SCE .093" copper) will lower about 1 compression ratio. Stronge studs like ARP will help to hold down the gasket and heads. 15 PSI is not a problem at all. With 15 PSI you are doubling the HP of stock. Stock is about 170 rwhp, double that is 340 rwhp.
One draw back about root style supercharger is that it can not provide high boost. Secondly, major amount of heat production after 9 psi.
Overall, i think its a good news. It will be great for dialy driver and street use. All out power still hands down to turbos.

Thankyou for your interest, the marine kit will not fit the car, but we are developing the car kit now.
We will be taking orders shortly so we can get the tooling started so we will be intouch in the next couple of days.
The supercharger is what we call a YT 1500 which is actually an Eaton M90 rotating group assembled with Aussie cast body components under licence. This configuration has better mounting points and a little more efficient in operation.
But for the real performance enthusiest the kit will also take a Twin Screw Opcon if big boost is required but this is not necessarry for street application.

Subject: Supercharger kit for Lexus 4.0
Hello,
There are many people in the United States are interested in your Lexus 4.0 Marine Kit. I have few questions for you.
1. Would your kit fit the Lexus 1UZFE cars. ie Lexus LS and SC 400 here in United States
2. What type of root style supercharger are you using? ie, Eaton? MP112?
3. If everything fit, can we do a group purchase? Once again, we have alot younger Lexus owners are very interested in getting power adders.
Your response will be greatly appreciated.

I'd look to weapon-R to tune the ECU w/ a piggy back unit... but let's not get into a ECU battle 
As far as the price tag, I'd be thrilled to see it stay @ 2.97k but I'd expect the price to go up... esp. for the first few buyers (paying for R&D)
None the less, we know the 1UZ can handle the boost, and we know that the tranny is halfway decent (JZA80 orgins) but the JZA80 AT will @ 450 RWHP start to fade over time... It'll take a ton of abuse, but sooner or later the 1-2 shift will get longer, then you'll bounce off the revlimiter a few times....
but w/ 450 @ the crank, it should be less of a problem, and for goodness sake! Change the AT every 15k like the manual says!

Final Thought: If you build it, they will come.

Well, here is one of the main reasons that I haven't bought a weapon-r ecu. They are located in Cali. Basically, for every mod I do, I want the ecu custom tuned. That is kind of hard to when you are on the east coast. Luckily, I am near swift racing. Hopefully, they will have something for the sc400 by december (probably not likely since they are so busy lately) or the ecu that may come with the supercharger is easily programmable so swift can help out.
But I am very excited about this project and saving every penny I have right now.

I visited a very reputable tuner today, who does a lot of supercharging for street and race applications (including IS200). They are / were quite successful in DTM and Formula 3 racing also. So I would think they know their stuff ...
I had them look at the SC4 to figure out if and how it could be supercharged and also told them about the kit that appears to be in the works.
They are willing to either do a custom setup (based on a 4th generation Eaton) or install and eventually modify the kit. They said that they would highly recommend an intercooler, even at a very moderate boost (4-6 psi). Although obviously cooler air is always better, I thought that the benefits of a intercooler at such boost levels are neglectable. What do you think?
Also, they suspect that with the stock exhaust, there would be too much back pressure. They would be able / willing to custom fabricate one, but that would obviously again add to the total cost. How would you feel about running 6psi with the stock exhaust?

I have been planning for this kit too. I have basically given in to redoing the exhaust and buying the headers too since they too are made in austrailia. even if the kit is gonna cost 3 k. I am planning on spending around 5 or 6.
