turbobanditen VS kkd manifolds
turbobanditen VS kkd manifolds
does anyone have experience with turbobanditens exhaust manifolds ?

holy crap!! thats really expensive! ill take the KKD manifold just cuz its like 100 bucks cheaper
KKD has 38mmx2mm, but can also be any other size you might need. Other common size is 42,4x2,6mm. Manifold can be twin or single entry and wastegate option as per customers requirement.
I always suggest to go with the smaller pipe for much better response. Does it flow enough? We've seen 1000hp gasoline engines using that size, so yes it does
His manifolds are mild steel and he's certifies welder for any material (except titanium, dunno for sure though) and would be able to legally weld any component to a nuclear power plant for example. Dunno about that for the Chinese MoFo, who made Turbobandit's manifolds.
Not saying they are bad though! But I feel KKD is more at the safe choice side and fully customisable _prior_ to welding.
Hope this helps.
KKD make alot manifolds around the world so those are used outside of Finland as well what i know all been satisfied the guality at KKD.
He are made those alot for just racing use as drifters or drag race cars.
Just don't put any wrapping on a mild steel manifold.
The debate for mild vs. stainless is not so straight forward as many thinks. The austenic form in 304 and 316 suits high temperature applications better than mild steel and withstands heat better in chemical point of view. And they are prone too crack if the larger expansion isn't taken in account in the flange and overall design. The most important thing for any manifold is to support the damn turbo!
And for any manifold, It's not the point 'if they crack' but 'when they crack'.
I would like to make mine of 309 or 309S as it has good chemical properties, doesn't need root gas. Basically it has the good points from both worlds (sst - mild)
Good to know Anton ;-)
But as you know I will have very little time for playing around with my car in the next month... :-(
Yes they are (Russians that is). To be honest, it's no matter where the product is being made but that matters if the QC is good or even exists...

Please tell us more about not wrapping KKD manifolds. What would you suggest, a coating of some type?
Would it be possible for Kalle to use 304, 309 or 309S instead of mild steel since he is likely certified for those materials?
I would much rather buy a manifold from KKD rather than Turbobanditen, I just wish KKD could use some grade of stainless, then I could use thermal wrapping on the runners. I used thermal wrapping on other project cars, and it does improve response, documented from datalogs before and after the wrap from less thermal loss, and lowers ambient temperatures within the engine compartment. I do not care about how one looks over the other, it should be mentioned

This confuses me a little bit.
Actually, at least from what I know referring to turbo technic, most of cracking in turbine housings occur due to fast changes between hot and cold.
So from this point of view, a wrapping should actually help to prevent cracking because of the heat isolation effect.....???

42.4 mm is outside or inside pipe diametre? Thanks

Outside is the standard measurement

Why? will it get too hot and crack or twist?
