K-Series 1.8k states of tune??
Discussion
Hi All,
Quick question: what were the states of tune for the 1.8k from the factory? Would I be correct in assuming they were as below:
1.8k std = 120bhp
1.8k SS = 140bhp
1.8k VVC = 160bhp
1.8k R300 = 160bhp
1.8k VHPD = 190bhp
1.8k R500 = 230bhp
Is the above correct? Also what was the difference between the 1.8k std and 1.8k SS? Just different cams?

There are two '140' engines, the original SS as described and the 'xpower 140' which uses much tamer cams and an ally inlet manifold that is a very poor fit to the inlet ports, these rarely make 140bhp and the cams are way toot tame for any serious horsepower, you would need to upgrade the cams as well if you have those.

I know you got vast experience Dave, so I am probably meddling where I should not. But just how sure are you about the x-power manifold bit? Reason I ask is that when I bought my 2002 SV second hand, it was stated as an x-power and I got the original receipt and spec. sheet from Millwood where it is also listed as an x-power.
But it had a plastic inlet manifold. Power wise it was at 137bhp.

Typical case of badge engineering.. The 'proper' xpower spec. used the trophy 135 engine which had some mild cams and a VVC inlet manifold. I suspect that there were stocks of Supersport bits and standard engines that were required to be shifted , hence they were badged as 'xpower' to fit the latest idiom. Chances are if yo have an xpower badge and a plastic manifold then you are actually a Supersport spec. which has the better cams.But it had a plastic inlet manifold. Power wise it was at 137bhp.

Hi,
I am new to the pistonheads forum, but have been reading the forum about caterhams quite a bit.
Living in Germany it is quite hard to find good (and experienced) resources about the k-series engines so I started out absorbing Dave´s page (excellent source) following the links and comments on this forum.
All those tempting tuning options offered at the DVA homepage have one significant drawback if you live in Germany as they more or less all require a free programmable ECU which is not road legal in Germany. I ended up ordering a remap for my RHD Superlight 1.8 from ZandF since Mark does his work on the standard Rover Mems3.
How is this related to this thread?
Before reading this thread I thought all 140 bhp 1.8k had supersport cams (being the part that makes the difference to the 120 bhp version). I now learned that the x-power labeled engines do not have those cams.
I asked caterham for details and they answered the following:
"The engine came with an VVC aluminium plenum and 52 mm throttle body which is how we got 140 bhp out of it, the rest was standard K-series X-power 1.8 engine with standard camshafts not supersport."
So now I am basically stuck with the wrong mapping for my engine.
Can anyone tell me, if adding supersport cams to my engine (in combination with the long 4 in 1 exhaust that I have) will eventually be a noticeable enhancement?
Where can I get those cams, since they seem to be sold out at caterham?
Thanks for your help,
Felix

Hello Felix,
You will most definitely need verniers, if the cams are then properly timed you should have no issues with emissions. The cams use the stock hydraulic followers.
It is probably best to send me a mail for pricing.. Dave@dvapower.com. I didn't mean it to come across as a sales pitch.
