Tuning much cheaper SS and MS manifolds (16v)

Tuning much cheaper SS and MS manifolds (16v)

It is, the 1.4 has an ally sump instead of the thin one found on the 1.2 (and 8v) engines - presume it's down to the thin ones rusting a lot (also helps with cooling the oil.. a bit)
 
Got the final piece to start on my 16v Conversion.

Ordered it from MotorsportWorld back in late June.
They told me i would have the manifold by mid July, however that date came and went. Dropped them a few emails and it turned out that the order hadnt been processed at the Supersprint factory in Italy.

Trouble is though by the time by order was back in the queue and ready to be processed, the factory was closed for all of august.
So was told that the manifold would be here mid september.
It finally arrived last tuesday.

Moral of the story; dont scrimp on price. With SS you know what you're getting and you know its going to work.

This is sad.

As to the bends, if you can weld, there are a couple of ways around it. First is, find somewhere that can do mandrel bends in that diameter. Second is to get so-called hygenic bends, much as Craig did for his turbo manifold. These have the disadvantage of being short sections, so more grinding and fettling is required. Third is to hydroform the material -- essentially you do your calculations, weld two flat sections of SS tigether with the required bend, incorporate a fitting, and blow the thing to shape with water (do not try this with compressed air -- you'll kill yourself). It's more labour intensive than mandrel bends, but much more versatile. A lot of 2 stroke expansion boxes were made this way.

For the welded on the inside of the flange thing, it's easy enough -- V the flange, tack the pipes from the outside, weld in the V and tidy up. The flange wwill almost certainly need grinding, to make it flat and clean it up, but then, it should really be ground anyway.

The SS manis look as though they're done by a robotised MIG. Fast and efficient (if a little ugly and heavy), but much too expensive for short runs.

The set up time (and wait for a sufficient order) probably explains the long waits.
 
My research and questioning of ragazzon has revealed that their 4-1 manifolds for the panda 100hp engine fits perfectly into the cento bay.

Downside is 4-1 manifolds are only useful for top end, mid range is nowhere near as good as a 4-2-1 manifold.

Who would really want to pay £800 for a ragazzon manifold and race cat apart from me :D?

Thanks

is the panda 100hp mani from SS any cheaper than then 4-2-1?
 
Does anyone knows the primaries and secondaries dimensions for Supersprint manifold? I am going to build my own manifold and I need these numbers to start with. JA seem a little bit on the big side with 38mm primaries...
 
Guy Croft put them up on his site a while back -- look for posts with my user name.
I found the discussion, thank you very much for your input. Do you remember if the wall thickness for Supersprint was 1.5 or 2mm?
Thank you in advance.
 
ycming, did snapped that of the ebay, because someone stow one from me yesterday :eek:
