yeah, the rotrex has its own oil circuit and as mentioned, the traction fluid is damn expensive but in this case there's actually a reason for it. that fluid has pretty special properties. if you look up the "traction drive" gear increase mechanism it's pretty neat stuff.
 
The heavy lifting for this kit is definitely the pulley set and the turbine mount. The rest - intercooler and intake, Rotrex oil cooler and reservoir, would be DIY'able for me.
If you put it like that, I'm the same. As I've got an f40 lid I've no space constraints so would likely use a larger intercooler or charge cooler than others. All that kind of stuff I can do myself.

Wow, talk about a long complicated road. I've been able to get my hands on the Lotus supercharged oil lines needed for this installation. I was even able to get a couple dollars off so i can sell them for retail price without losing money. They'll be going for $160 and i'll have them in my hands tomorrow. More should be easy to get at this point but easy isn't quick. these have taken about 2 months to get.

Picked up the lines today, they are the correct lines for the application so if any of you guys need them i have 5 in stock right now. these seem like they'll take 8-12 weeks lead time to get so i'm pretty happy to be able to make them available for you guys.

I owe you guys an update. I know many of you guys are waiting for this thing but i'm running into excessive manufacturing cost issues. This is actually the same issue I've been running into for the 2AR-FE swap kit for the MKIII. the solution there has been to find different manufacturers to be able to pick up different manufacturing methods like castings instead of getting everything machined from billet.

Unfortunately that means more delays for the 2GR supercharger project and i apologize for this but it helps nobody if this kit is so expensive to buy that it would be cheaper to buy the Lotus supercharger.

(if anyone's currious to keep track of the 2AR stuff, it's right here: spyderchat.com/forums/showthread.php?116977-Thoughts-on-a-2AR-FE-swap-kit-for-the-Spyder )

So it's been brought to my attention that the whipple chargers are about $3000 new and i think they do get used in several stock applications. I'm not saying I'm changing direction yet but i want to make sure i explore all my options.

The big issue is these brackets are too expensive to get manufactured and what's changed since last time i explored this is i can get a casting made for a "reasonable" price. previously this was way out of the question.

so with this new info, let's explore which superchargers are available used from an OEM application and yet are available in the $2500 range new. i don't want to build a charger that requires digging for used parts because that's no different than the immobilizer issue. that requires people to hunt for used parts and most people hate doing that.

I also want an efficient unit, I'm not considering the old M90 units from the GM 3800's. It would also be very preferable if the OEM snout configuration was available aftermarket so only one configuration needs to be made.

The motor wants a supercharger at least 1.2L per revolution and a large pulley could be worked out on a charger up to about 3.0L per revolution. for the whipple this means the W100AX(1.3L), W140AX(2.3L) and W175AX (2.9L) would work. the W200AX may be workable if the used application is particularly fantastic but the 5" pulley required to keep the boost under 10psi would start to be a bit big and annoying to fit.

I'm also open to other suggestions. the new production methods may open up ideas I previously rejected. Some of the ones with high tooling costs may require a group buy style setup.

Have you contacted Harrop at all? They have the HTV1900 (The big brother to the TRD supercharger) for $3080 AUD (~$2300 USD)

https://www.harrop.com.au/shop/automotive-performance/superchargers/htv1900-supercharger

You can get the HTV1320 for the same price too.

Cheers,

No, i had not thought about that. this is why i decided to bring this up again. My capabilities have really improved since the beginning of this project. The lack of ability to get castings made was really holding me back and now that is out of the way.

With that said, the TVS units are nice but do they come in any stock applications to have a cheaper offering possible? This isn't a strict requirement but it would be nice to have a cheaper option available for those willing to search for parts in the junkyards.

I believe these are also used in the Audi 3.0T engine and Jaguar's 3.0, but with built in intercoolers.

can you post a link to that so i can look at it further? I suspect for that price it does not include the intercooler. i also think it's probably a bit too big to fit under the hood.

got it, so it does not include the cores when purchased new at that price.

Also now that i look at it some more i think the snout is a bit short to reach over the cylinders without a really complicated intake. I think we should keep looking elsewhere.
