Identifying Knightsports twins.

[Matt_K]

How many different versions of knightsports twins are there? Can they be identifyed by look or something?

I\'ve been stripping my engine down today in preperation for taking it out and I saw this. Any clue to what they are? There is some faint engraving on there, but I can\'t for the life of me remember what it says.



Thanks in advance - Matt

Ya lucky bugger iv just payed £1200 for a set of ks twins haha

They only do 1 off the shelf conversion to stock twins and the specs they use are pretty dam good
 
They are called the RF420 high flow turbines. They have reinforced internals aswell as a larger journal bearing compressor wheels that are 20% larger than the stock ones.
 
Hope that helps.

Thanks great help - I was told it had high flow turbo\'s on when I imported it, but it still has a stock fuelling system, so I was unsure as to the truth of that.

Pip could only map it to .8 bar to keep eveything safe. Time for a new fuel system I think...

Yeah sort the fueling out and have some fun with them they are great units.
 
We have had great results with the twin SARD fuel rail kits not the cheapest mind you but very good. We did a kit for a guy in last week. He had a TO4E on his so we sorted him with the Twin fuel rail kit, 800cc primarys, 1000cc secondarys and Bosch 044 pump. He was very happy with it.

What kind of power can you expect from the KS twins - say compared to stock twins, full exhaust, IC & fuel mods which is usually around 320fly?

mr hudsons running 350 at the wheels isnt he?

[jm-garage.co.uk]

John Hudson made 369.9 (436 @ fly) @ 0.9 bar boost at the wheels on stock ports which are restrictive as you know over say street port.

[interloper393]

wow! thats great figures, so porting you`d see about 400bhp at the wheels nice..

I translated the text on the badge for you bud.. it says.. " Give the turbos to Craig!"

[jm-garage.co.uk]

There fantastic turbos indeed

dude, I had 320 RW with those mods (+ WI) so better get cranking up that boost :3gears-rh

[John_Hudson]

RF420\'s for the win : )

[JBerg]

How do these compare to the BNR stage 3\'s?

Nice numbers for the stock ports! :Thumbsup!

Ha ha ha, indeed my man! :Giggle

Must say im interested in these KS twins.  Stronger and more air, sounds ideal! :cool

edit - 320 rear wheel WTF!  I managed 275RW (I think) with the mods!  Ok i\'ll see what the new engine does
