Yes Inventor FTW.

Looks like a fun build!

^see this man knows

He sold the car to a friend and now the car is back together with a new heart.I'll try a get him to post about it this weekend.

Total Cost? I am really wanting to do this. I was interested in a RB20 but this is slick!!!

Then you figure it out, with your money, and quit whining. Ok? People do stuff for a reason, Money, not because some kid on the InterWebZ is Gonna give him a smiley face or some dumb shit. Get real.

This isn't exactly rocket science. Well in a way kind-of. But if you want something done right you have to do it yourself. Didn't your mom ever tell you that???

DGTRIALS513 · 11-05-2009, 09:15 AM

Damn dude you should calm down. I just wanna know a rough estimate so I can make a choice on the winter project. I use to work at a machine shop so I have a decent machining connection. If it gonna be super expensive then I'll stick to the RB swap. And yeah Im sure the tolerances of the bolt positions have to be pretty tight to get it right the first time. Plus I don't think anyone can help tune that setup around me. I could be wrong though. There is a reason it is a rare build! Plus I am pretty lost on the methane/ water injection. what does that do exactly? Seen it on another setup on you tube...
Thanks

I also have a H20/meth injection setup going on along with a high / low boost controller switched inside the car.

should get me close to 300whp!

How the heck to you use a cockpit adjustable boost controller with a supercharger? The only way to adjust boost is changing the pulley sizes.

Updates with fresh KA please!

this is tight. cant wait to see vids.

I'm totally down for some super custom electromagnetic actuated 2 speed hydraulic clutch with a high boost pulley on the end of the M62. flip a 2 or 3 position switch an voila!

Changing the blower speed is not the only way to control boost level. Its common to see a bleed valve on setups with a blow through style MAFS. Ideally you would measure your engine belt speed and find the P/R and desired CFM, given a certain percentage of loss across compression, and decide on a pulley ratio to achieve this output. The bleed valve gives you the opportunity to change the blowers output without affecting the belt/pulley dimensions

Nissam MAFS are not up to the task of handling pressure. Subaru, Mustang or the awesome 85mm - 97mm ABACO MAFS would be the ticket to handling the boost.

You could control boost through a MAXFLOW Mondo (or your fav adjustable bov) on a blow-through, as long as it installed (far before) before the MAF. By the time your sort out all the ideal distance between components, the intake plumbing would be a mess... Not at all impossible though.

I'm considering a centrifugal compressor... TopMount Turbo setup may be for sale.

I've seen 350Z's holding boost on centrifugal setups; its not impossible but requires a little attention.

It you look into Rotrex, hit me up I get dealer pricing....
