As some of you may know, I cobbled together an epoxied adapter intercooler for my build that allowed me to bolt on a M122 supercharger. Fitment is a huge issue with my giant intercooler core (am using a stock cobra core), and I always fully intended to replace that piece with a properly done machined/welded aluminum piece, and the time has finally come to order the raw materials...so the question is, should I order 1 set of plates, or multiples?
So why do this? Turbo power levels, without sacrificing the awesome low end torque and instant response of the supercharger. Secondly, cost. Third, convenience. M122s can be had in like new condition on ebay all day long for around $500. The TVS blowers are harder to find and still run $1,500-2,200 or so. Obviously you will need supporting mods, but you do with a turbo as well, so I don't count that part of the cost when comparing to a turbo setup. Theoretically, this could be installed in a couple hours vs the 10 hours it takes to install a basic turbo kit.
These plates will accommodate either the M122 supercharger from the earlier GT500s, or the new TVS2300. They are 35%, and 55% larger than the stock m90, as well as having much, (MUCH in the case of the TVS) larger inlet and outlets and higher efficiencies. They have a 10-rib drive pulley, at this time I am running mine on an 8-rib ZZP setup. At this point, you would be on your own for the throttle body side of things as my setup is significantly different than the northstar TBs or whatnot that most guys use.
As an added bonus, the adapters will come drilled and tapped for 6 1/8" NPT water injection ports, and 6 1/16" NPT nitrous ports for direct port applications of either type. All you would need to do is drill your lower intake accordingly, and if you don't want to utilize them, just don't drill your intake. Put plugs in them if you feel the need, but if the holes in the lower intake aren't present, there shouldn't be the need for that. I have yet to see if there will be fitment issues attempting to install either or both of those setups, but I intend to build the option into the adapter as best I can anyway.
As far as fitment goes, you would need an alternator relocation bracket, and probably in the neighborhood of 1, possibly up to 2" cradle spacers (which I can provide, plus longer bolts), to clear the hood. Granted, my setup needed 2" to clear the hood, but my present intercooler is like 4.5" thick and buried a couple inches into the lower intake whereas the new plates will sandwich a 1.25" thick bell intercooler core and have a total height of 2.25".
So, what's the cost? Well frankly, this first one between all the crap I've bought trying to make it work, will probably have cost me well over $5,000. I think I can get that number down to something that could reasonably compete with an entry level turbo kit. I won't know final pricing until I have one built...but for a first run, it would be around $1,300 for an intercooled version and $1,000 without. If I had a large enough group buy situation going on, I think we can shave a couple hundred off those prices. In addition to that, you would provide your own supercharger, figure out your own intake situation, and your own alternator relocation bracket, various other little odds and ends, and modify your own lower intake as you see fit (basically cut as big a hole as you can in it). I can provide thick cradle spacers and longer bolts at an additional cost of approximately $100 for 4, $150 for 6...you're on your own for camber bolts/alignment or whatever you'd want to do on your setup. 3" doesn't appear to have caused any major issues on my car (although I'm not saying it's "right", I leave that decision up to you).
So, basically I want to know if there is any interest. If there are any serious buyers, I will order the extra materials for a $200 non-refundable (except in the event I scrap the idea and offer no finished product) deposit. Reply here, and/or PM me. I will want to order stuff fairly soon, so let's put the end of February as a tentative deadline. Thanks for reading!
