Greg

This Repo Dual plenum cost 600 Pounds?? How is its design compared to the Dahlback?

I think also that 600 Pounds is very much isnt it?

Mark: I'm not much into mechanics but aren't the holes too litle ? with all that trouble we are faced to make intake freeflowing without restriction in the end to face one plenum with 5 small holes ?

not sure what effect smaller individual slots would have over one large slot, but as long as the combined area of all the slots are equal or greater than the area of the throttle body I cant see it being a restriction?

dahlbacks new manifold still uses runners from a stock manifold.
Id definately buy repos one.
But if Mark will make me one like his LOL....go on Mark

How much does Repos cost?? Can it be fittet in an RS2 with Aircon in place?? Anyone runs with it?

I could be wrong but I think it was designed to fit with air con. You'll need to ask the maker or Aelred to know for sure.

Does repo one has velocity stacks as Mark H has ?

[repo]

Hei,

I see lot of interest for this product. Some flattering comments, some not so positive.

Yes, there are velocity stacks inside the manny.

Head flange and first couple of cm's of runners are cut from stock manny.

Price for such is 1100eur, without stock unit to start from, 900 eur, if You provide me stock one in replacement.

Lead times are long, as I work alone, and thanks to this forum, and friendly feedback, there are lots of customers ordering parts from me.

Pics of manny under construction

Offtopic, but once I started, I can also advertize these

We also provide exhaust mannies made of fireproof steel nowadays:

Happy tuning lads.

Thanks

Very nice wood floor

What's wrong with the runners then? The space is so limited they have to be short in this IM configuration. Or is it the inside diameter? The bigger is not always the better! Larger diameter means lower velocity and lower velocity means worse cylinder filling which means worse VE (volumetric efficiency) which means less power.
The basic principles do not change when boost is applied.
