I was browsing the net this a.m. (shoulder in splint due to reconstructive surgery), and saw something relatively new (2013). It's a manifold offered by a couple of brilliant English engineer/fabricators, so you can mount an OEM BMW Eaton blower on an A-series 1275 or 998: http://www.podifold.com

Best of all, you can go EFI, as they offer an injection-specific setup! I am going to contact them to find out about the height of the unit toward the front where the unused flange over the pulley sits. But one could simply cut that off to match the slope of the bonnet. At worst, one would need a little power bulge--but in this case, I wouldn't mind it!

This may, at long last, end my desire to opt for an engine swap.

Happy holidays!

Joel

About $500 gets you a used blower from Ebay. With the left side blower outlet maybe a right angle fitting could route pressurized air to an intercooler just behind an RB-style vent in the valence, then back around the right side to meet up with the carb. One of these with an appropriate road cam would make more power than my mildly cammed A15 Datsun, with no chassis mods. And my A15 makes the car one hell of a lot more fun with the ability to easily and safely pass on remote curvy two lane highways. Maybe put it all together for less than $2000.

Dear Tom,

The picture I added is not the best of the few they have posted - sorry. Here are a couple more showing the kind of zany intercooler pipes people resorted to on Minis. But as you note, there's a lot more flexibility for the ductwork with a Spridget. And a blow-through system has the intercooler benefit which the Moss draw-through lacks. Never liked that shortcoming of their design.

I agree that the cost could be modest with a used blower, and I appreciate the link. But I note that the pull-n-pay lists superchargers at $44.99 plus $6 core. (I know that sounds wrong, but it isn't; they sell engines for $250 and trannies for $109 (with core)). So, we're talking a really cheap hot-rodded engine if I had the machining done and assembled it myself. No biggie. I mean, a set of low compression pistons isn't that much, I wouldn't think.

This is exciting.

Joel

Argh... I now see that the website has no live links to add a manifold to the cart, and no contact info. There is a lengthy post on another mini forum with lots of photos of iterations of the design as they worked their way to the fuel injection version shown in the lower two photos. The top photo shows the carb version.

Here are a few of the fuel-injected version showing where the injectors go. At first they had them where the carb resides, using the Specialist Components throttle body, but it was too far from the intake ports. Now, they're roughly where a carb or TB would sit on a mini cooper manifold, as in the DIY EFI setup I'm working on for naturally aspirated 1275s, also attached.

The inlet manifold was changed to allow use of a simple 90-degree silicone elbow to connect the dump valve from the same BMW that the blower came from. It connects to the big top-facing port near where the return from the intercooler goes--or the carb if not running injection, in which case the port is blanked.

OMG! Joel, this is the answer to my prayers! I have a '72 Midget 1275 that needs an engine rebuild or swap, so a stout blower motor rebuild on the 1275 with one of these would be terrific.

Thanks for bringing it to our attention... I'm so psyched to use this setup.hot smiley

Trevor - thanks. Does his car have one of these podifold setups?

Shawn - no worries. I'm going to grab a blower from the pull-n-pay for $50 next time a BMW of the right model/year gets wrecked. It seems like a worthy investment--assuming the podifolds are still being made. Clearly, marketed via their website, but as I've said, weirdly there are no live links to order one or make inquiries. Well, even if they aren't being made, I want a $50 blower to fiddle about with. I spent last night dreaming of an intercooler behind the front lower valance, where I was planning on putting the oil cooler. Maybe now it'll just stay where it is!

Great find Joel! Are the M45 blowers exclusive to the "S" Mini's or did Bimmer run them on other cars? Haven't been to a local Pick n' Pull in a while but around here, I think the BMW/Mini wreckers usually get a hold of wrecked Mini's first. It does seem like there are a lot of "S" models being parted out on CL although the ads are mostly posted by dismantlers.

Kent,

Luckily, the answer is 'no.' The M45 was (and is) made with lots of air intake configurations, and fits a wealth of cars, such as the version for 203 Mercedes SLK 230 (post face lift SLK's):
* Displacement: 0.733 Liter
* Max. Outlet Pressure: 2.0 Bar
* Max. Speed Cont (inst.): 14,000 (16,000)
* Flow at Max. Speed @ 1.8 Bar: 630 cubic metres / hour

Here is a link to some Eaton models: http://victorylibrary.com/supercharger/super-eaton-data.htm

Now, if Podifolds turn out to be no longer sold, and a simple DIY draw through was the resort, why couldn't one of these or the Mini's configuration mount sideways next to and down from a Minispares manifold, using an adapter and mount setup, and with the throttle body aft as with the Moss setup?

As for availability, yards have differing policies, but the multistage pull-n-pay I like refuses to hold parts for anyone, including dealers; it's first come. You can set up car alerts though, so you can hurry down there. So, I'm getting a couple configurations to fool around with, as $50 fits my budget just fine!

The one in the video link is not a podifold IIRC.

Very interesting! A guy in Nunnawading (not far from me) called Hans Pedersen runs a business next door to Link Automotive to supply and fit superchargers. I don't know of any progress by him on fuel injection mods though.

I'm glad you still have the bug!

Joel,

I did some digging and I don't think the Podifold manifold has made it to production yet. The designer was still making design changes to the manifold just a couple of months ago. So there's still hope.

It does appear they are "stalled" in bringing it to market. Joel, I'm with you on trying to source a nice Mini S blower and stuff to possibly fab an intake.
If we can get ahold of these guys and ask about production, I was thinking if we could do a group buy of 5 or 6 say, and that might make it more attractive for them to have a run made at the foundry.
I've been trying to go on sites that have messages from them about the Podifold, in an effort to get contact.
This really does get me excited to try! Hell, l'd even try to do a suck through system, just to get it up and running... oh well, to dream!
