Have any of you EFI guys used a DCNF style throttle body? I'm curious to know which set you used and why. From the quick research I have done, there are only three manufacturers for this style of throttle body....Jenvey, Borla(TWM), and Weber/Redline. I'm really looking at the throttle arms and how to adapt to a VW type 1 throttle linkage. Any info will be appreciated....

Buddy of mine in Germany used the Jenvey 40mm set on his 1200 Challenge Motor. They look awesome!
Other then that I really can't answer any of your questions.. sorry.

I would like a set myself still though, unfortunately they are pretty $$...

Thanks for the info... I'm looking at these for an option to feed a 2332. I just need to find a set of Berg type 1 DCNF manifolds.

Sold some stuff and got a set of Jenvey DCNF's in 40mm because I could get these awesome (custom one-off's, not for sale) intakes



Its for the 1200 N/A project

Since Max has subscribed I felt obliged to update a little..





Super proud of this as there is no airfilter for sale anywhere. I made these from a set of round Pipercross filters that I simply cut with scissors (spelling?) and glued together again with superglue




The engine is in my buggy, but this 1192cc is so short (6mm flycut into 043 welded heads) that it would fit in any bug with these manifolds anyways.

Building a header and exhaust system for this atm, trying to keep equal length as much as possible and still allow for proper spark following at the 4-1 piece.


Its a crazy and totally useless undertaking to do all this on a 1192cc, but we have a dyno Challenge for 1200 engines each year here and of course I try to win the N/A class

Was looking to make a similar intake for my bus with fabricated manifold with individual 36mm throttles on 70mm centres and much longer runners
I think the DCNF are 48mm centres

Yeah, longer runners in the manifold would probably be better for torque, but these were as is. And it keeps the engine somewhat less wide (although not a problem with this platform (Buggy)).

Still, longer stacks could help a little too was the idea, so had these printed in 10cm (4") height:

Love it
