Downing Atlanta Supercharger (DASC)

[Alpine003]

For anyone else though . . . even if you paid 10k it would probably be a better deal than buying a car and doing the same stuff to it . . . mind you its been repainted, has HR + Koni suspension, and kick-ass 10lb BBS wheels.

$9500 since it doesn't have the original Recaro seats.

[Hey-u]

anyone interested in trying to get a group buy going once the kit comes out for the e30?

Did anything come of the group buy querrie re DA supercharger? I would be interested.

+1! Conditional on CARB cert...

I still find the HP figures a little optimistic. 127 at the rear wheels is 93% of factory rated 136 for a stock M42. Even so, the final 187 in the "real world" is  about 170 HP.
Downings latest ad indicates CARB legal also.

Pray tell, what did GRM do to address the lean condition?'

I found some more info on the GRM car. This follow-up tells about what they did to deal with the lean mixture . . . no small task:

The PDFs of the articles are also posted there.

Someone should really buy this car. They've put a lot of work into sorting it out.
