It could just be me, but why would you run a turbo that small and a supercharger that big, it's back to front.

No idea, but the fact that there's no intercooler just means by the time the already hot air gets to the supercharger and gets even hotter, the turbo will have a nice time...

That engine is going to die so soon.

Its prob running on methanol and has some sort of water injection to compensate for no FMIC.

The turbo is only feeding from 2 cyclinders also so it would be slow to spool up.

That said, they are americans so who know whats they were thinking!!

a few points i noticed:

1. blower looks like an eaton M90 or M112 lysholm type.

2. that's a big enough twin-screw on a little 4cyl honda on its own, let alone twincharging it like that.

3. no aftercooler between the system and the engine = ridiculous intake temps, it must run meth or C16.

4. maybe the turbo has a large a/r exhaust housing, the main reasons to twin charge like this are to spool up a large turbo very quickly, and to keep intake pressures above exhaust back pressure, so the theory is you can run a larger snail for a smaller engine, with no real drawbacks.

all in all, a very strange looking twincharge, but the principles are the same as my setup.

perhaps there's a water/air intercooler between the blower outlet and the inlet ports on the head? they don't have to be large in volume and can be packed with icy water for quick track sprints. i like the remote-drive they set up for the eaton there, very innovative.

      If there's enough meat in the housing where you want to put the M12 adapter, then do it, but be aware that if/when you f**k that up you'll probably be repairing it before doing anything else. I'd just drill it out and tap ina 1/4" thread. No need for rocket surgery when the next most obvious thing will do. You could throw a 1/4 x 1/8 bush in there and use the same fitting you intended to use.

      What should I do next to hold the head on

      By Murray_Calavera · Posted

      Is the only issue that the oil catch can is getting filled on hard runs? I'd be thinking more about oil control issues rather then the head lifting, especially as you aren't seeing spiking in the coolant pressure.  Do you need restrictors in the head, or better drains from the head? Does the sump need venting to the catch can?

      Tried to make 1/8npt threads into compressor house of the turbo for my EBC. Threads got fu#ked and ended up with and elongated hole, so I do have good amount and nice threads 90% of the hole but 10% I only had 1-2threads there and rest of it is flush on that side of the hole.. So my idea is to do M12 x 1.25 to AN4 with braided lines instead of 1/8npt to 4mm vacuum silicone hose.  and hopefully get a better thread. M12 is quite big and AN4 is a little bit bigger than 4mm (4.9mm inner diameter braided PTFE hose). but this should work. Thoughts? Otherwise I will weld and adapter onto the turbo.
