BRP "Hotside" Supercharger

Yep, I should have mentioned that I'm hoping for the coldside kit that Fast Forward Superchargers is developing, not BRP. FFS says $3700, a lightweight kit (37 lbs?) and CARB. They use a 5th injector to cool the charge and supplement fuel.
Lots of advantages to this setup. The only downside might be that without an intercooler/aftercooler option, you will be limited to the max power you can make. I'm ok with that though, as long as it can deliver >300 whp and a nice fat street torque band that the PD Eaton MP62 should deliver.

IIRC, the FastForward coldside is actually the original BRP (now SOT) design. I'm not sure which caused the other, but BRP dropped the project and the guy that 'owned' it moved to FastForward and brought the design with him.

I don't like the 5th injector method of fueling. What's to say #4 will get the same fuel as #1? With 11.3:1 compression, this isn't something I'd like to fool around with. It could work for a low boost setup, but I'd rather have all 4 injectors putting their own fuel out to each cylinder.
It would be great if they could incorporate laminova coolers into the plenum/runners, but I just don't see that it's a cost-effective solution.
The FFS coldside will not use the stock intake manifold. I also wonder about how good the 5th injector setup has been for Fastforward's Miata customers. They might be bumping fuel up at the stock injectors and then just adding a little for evaporative cooling. I hope they check AF at each cylinder. Maybe its time to post some questions over there.
I won't need CARB but I will need to be able to read the OBD, so if the BRP setup works with a piggyback control then all is well.

I honestly do not see how an MP62 SC will fit on that side of the engine. The adapter manifold (part that replaces the intake manifold and that the blower bolts to) will need to be no more that 1 to 1.5 inches thick to clear the stearing linkage, brake master cylinder, etc... This will leave very limited room for the injectors and it will need to have some very thin intake runners to get air to each cylinder. Then there are also hood clearance and other issues to contend with.
I hope FFSC is succesful, but fear it will end up not happening. If it does I will take a hard look at it - even more so if it happens before my BETA BRP/SOT kit arrives.

I'm also holding out for the coldside setup, mainly due to light weight and much lower cost.
Dayum these SC kits are taking a long time to finish.

As has been said, don't count on that for the S2000 any time soon. They're trying to finish their S2000 hotside and 3rd-gen Miata centrifugal kits at the moment.

Any news on this?
I will hopefully have it on the road by the weekend and provide a detailed install report soon there after. I am very impressed with the fit and finish of the kit parts so far.
This is the non-IC kit, I will update to the IC kit when the parts are finalized in a few weeks.
Right now I am waiting on them to send me the crank pulley assembly and piggyback.
Here are some teaser pics:
