Jag supercharger for jag engine?

[rocket5979]

The idea is we are going to run 5psi on Stage 1.
Stage 2 - 8psi with the Snow Performance cooler.
Stage 3 - forged internals and such.....

Man custom forged internals = some serious mula for these cars! I talked to Oliver(yes I know, super expensive) and I was astounded at the price they quoted me for a set of custom billet connecting rods alone! Whew! I think I will wait for someone else to get the ball running on this one before I join in. I will stick to 6-8 lbs boost on a centri for a while once I start mine.

That's exactlly where I'm coming from. Just more daily driving hp.

well seeing as were on the subject of a supercharged 3.9-liter... did eny one else see what ford had done with the concept 2003 thunderbird Link

What ever happened to that setup?

 

[Quik LS]

it died with the McLaren LS - not enough demand from the dealers to sell a high-pro version of a vehicle that is already hardly selling.....

Exactly! I already got a vehicle I plan to race. I would be happy with about 375-400 fwhp on the LS for "passing power".

screw the supercharger if nobody can figure one out, how did that guy get the rear mounted turbo, i would be happy with that. i want plans

not sure why you say " if nobody can figure one out " ...

The intake mounted supercharger will be a heck of allot harder to fab up than a centrifugal supercharger. A centri is pretty simple actually, you fab up the mounting brackets and then fab the tubing and your good to go. Allot more leeway for custom placement and design with a centrifugal than a positive displacement(Eaton roots) supercharger. The turbo is another route to go too. Getting a turbo or supercharger itself is not going to be the hard part of a project like this, it will be tuning for it and also making sure you dont have any breakage.

If the centrifugal is so simple why hasn't anyone done it? I guess I could answer that myself because there is basically no market for one. Just a handful of owners who want more out of their daily. Also, another main problem is lack of space to mount a turbo/supercharger(centri) in the engine bay. I have yet to see a centrifugal type supercharger or turbo(in engine bay) installed on an LS.

Correct - plus the $$$ for a centri is much more.

IF a person knows what they are doing and knows the constraints of the project they are working around and keep all of those in mind while they are building it then it will be relatively simple. You are right that there is no market for one. That is why it is going to be done custom. From the high compression to the lack of aftermarket for these trannies to the TBW for the 03+ LS's all do lead to some hurdles to cross. Those hurdles already mentioned would have to be crossed with any aftermarket forced induction. As for the centri fitting into the engine bay? Well I know it is tight and all but things can be relocated. Stock for stock there will not be much room but once you clear out this little fluid tank or a few other minor things you will find a way to make enough room to get the head unit and its intake ducting in there too. There is a possibiliity that the stock hood will have to be modified to make it fit, but rest assured it will not be anything crazy like a 4" cowl hood or anything that will make the car look like crap. There are hurdles with the centrifugal too, but they are allot easier to get over while not having a CNC machine available to you is my point. Take it from a more creative and outside of the box POV and you will be less skeptical. I may be new to this site but I am not new to the race crowd and to custom drive bracketry fabbing or just general overall fabrication with metal. There is a way, you just got to see it and not be so apprehensive to take it.

Not at all! Figure that instead of getting a centri kit, your just getting the head unit. Most of those go for less then $2,000 from the Vortech S trim($1,750) to the Novi 1000 for ($1,550). Considering that the Roots types are going for usually well over $3,000 at the lowest and you really have a viable alternative! All the bracketry will be made in-house with having to order one or two ball bearing pulleys for the tensioning system. Then the actual tubing can be done at a local, yet reputable, exhaust shop or by yourself if you have access to a TIG welder and are pretty practiced up. The exhaust shop I got my trucks exhaust done at was going to hook me up with a custom piece for my other custom supercharger installation before my vehicle was totalled. After that it is a matter of grinding it and sanding it to make it smooth and then send it off to be powdercoated in your favorite color if you so choose. Tap and run the oil lines(if needed) from the OPSU and to the pan and then do all the rest of the normal forced induction mods such as injectors, reprogrammed MAS, base tune with Xcal2 and datalog it in normal driving conditions for drivability, then take it to the dyno tuner for fine tuning and safety and that is pretty much the gist. I dont know about you all but it sounds like a blast to me. I have been itching to do a project like this again for the last 2 years.

Anything is possible with cars. It's all about the dollars though, it's always about the dollars.

To put it this way, if I had the money to heavily modify a LS, I wouldn't own a LS. Maybe something along the lines of a XJR, M5, S600, etc.

The thing is that what I am talking about would not cost that much to do. I mean it will not be like buying a Happy Meal at McDonalds or anything but it will not be really expensive either. It would cost less than a conventional supercharger kit would because some of the expensive stuff like the bracketry which runs usually a little more than $1,000-$1,500, will be fabricated at the home steel workshop with a oxy/acet torch or plasma torch drill press, chopsaw, 4.5" grinder with cutoff wheel and brush wheel attachments, tap and die set, very accurate measuring, and the charger head unit and car (or very accurate template) sitting in front of you for measuring reference. A person would be surprised what kind of quality stuff can be made in a humble steelshop with simple tools. Sometimes people forget that you dont need a $50,000 CNC machine to fab metal parts. You cannot mass produce stuff this way but then again you only need to do just one.
