Hello,
Thought I would put up a few photos of my Sylva Riot at Knockhill's Super Lap Scotland championship. The championship is based on power - weight
with all cars on 1b listed tyres. I got the lap record in my class at round 1 but after a trying time at rounds 2 & 3 with handling issues and a
damaged throttle cable it got beaten by a 10th in round 3.
As far as I am aware Knockhill is the only circuit in the country which has a license to run in the reverse direction which means for double header
events you run one day in the normal direction and the other in reverse.
Cheers
Steve
Nice work. I like the knockhill circuit in reverse. Your a brave boy with them kerbs they are especially brutal!!
Great pictures and you are certainly giving it some beans
Nice exhaust solution too...why have I not seen this before?
Good stuff
Do you have any video?
How do you find the ZZS compared to other tyres you've used?

Thanks a lot for the info - seems all the feedback from the ZZS has been great so far...
Re: exhaust - could you just reduce the length of the plain section between the manifold and can, then make a 180 loop out of the can to get the exit
a bit further back, rather than re-engineering the whole thing? Should end up same weight overall hopefully, and keep your weight distribution the
same (good idea, btw).

Slightly off topic..... What size wheels/tyres with what hubs are on your Riot?

I run 13" x 6" front and 13" x 8" rear. It originally had 6" wide all round but I couldn't get any balance with the car roasting up its rear tyres while the front were still cold.
Thanks, explains why It doesn't look like I can get 13's on my riot. (On original set up) :-(
Well it's been a while since I saw that car. Previously owned and built by my brother, some bespoke bits on their like the rear uprights. Great
to see it looking better than when it was sold, and competing too.
Keep up the good work. Does it still have the 1800 zetec in?

Very nice looking car. I guess the exhaust would be a lot noisier and smokey for a passenger on the road? That's if it passed an IVA!

My brother and I made the exhaust in this style to counterbalance the weight of the engine and driver instead of having it hanging out the back.
I got pulled up at the last round and told to change it for next time as it is not compliant with the MSA blue book which states, 'all exhaust outlets terminating behind the mid-point of the wheelbase of the vehicle'.
I would of been tempted to double silencer that exhaust. On can on the run forward, 180deg bend, then another can on top running back. It would be
nice and quiet then.
Then only disadvantge would be the weight, which it seems you dont mind adding if its in the right places.

All Avon ZZR tyres are now List 1C (expect two specific OE coded Caterham ZZRs).
On a track ZZRs will likely out-perform ZZS but around 1 sec per lap.

They are the same compound as the normal Medium ZZR (rather than the A24 compound sprint). I've used the mediums and they are the best old 1B
for more than a couple of laps.
There is an argument that the MSA will restrict the OE ZZRs to the car that is was OE on, ie certain Caterhams. I understand this was their intention
but it wasn't written that way in the blue book so expect that to change.
So... It's been a while since I've posted up here...
The Riot has went under a bit of a transformation. Over the winter, well, actually the end of the summer, autumn, winter, spring, and summer, I have
removed the Zetec and went for a 2.0 Duratec with SBD throttle bodies, mated to a 6 speed sequential box with a paddle shift.
Still a lot to do to tidy it up but it runs and goes. After an unsuccessful 1st outing with a clutch failure I've got a track day booked for the
30th September so hopefully get some videos up after that.
Cheers
Steve
Great choice of engine, what output have you ended up with? Only ask as the inlet being so close to the bulkhead must sap some power
Thanks, it made 196bhp on part throttle on a standard engine. Only realised it wasn't making full throttle when someone pointed out that the cable termination on the throttle bodies was stopping the full travel, apparently it's a known issue with the SBD throttle bodies which I didn't know about - my own fault.

looks fab
Have always loved the 'purposefulness' of the Riot. It looks like it was designed to do just one thing - drive feckin fast!
I think if I was to build again, then it would be right up there on the pick-list. Either with CBR1000RR and chain drive, or a Sigma / Zetec-SE
engine to keep it super-light.
So...
A lot has been happening with the car... huge amounts of teething issues and with the car being a race car and not road legal it has taken a lot of
every resource I have to get it to a point where it's running and reliable (fingers crossed).
It's Superlap Scotland rounds 2 & 3 this weekend so hopefully the Scottish weather stays on the favourable side of the kit cars and we have a
reliable round - as always couldn't have made it this far without my brother there to help.
Hopefully be able to post up some good results and videos after the weekend.

Nice one, good to see it evolving and hopefully it will do the business in competition, good luck
Been a while since my last post...
Competed in the first round of Super Lap Scotland on Sunday. Super Lap Scotland is a series based on power to weight which consists of warm up and
practice sessions, with a 15min qualifying and a final single lap shoot out.
Firstly, I have to thank my brother Matt Henderson for his continuous support with car preparation and track support.
Warm up / practice
With the Riot having corner entry oversteer and mid corner understeer I was very happy to finish the session with a 56.8sec lap, my quickest official
time round Knockhill
Qualifying
With a time differential of up to 15sec per lap between cars, I knew the issue for qualifying would be getting clear track for flying laps. With only
a 57.1sec lap on the timer and ultimately a driver talent failure, with the session ending with me in the gravel at the exit of Clark’s, I was over
the moon to be 2nd, albeit 1.2sec behind 1st place.
Final
The final started off well with but unfortunately ended with a 360° spin on the exit of the chicane.
Pretty chuffed after all the reliability issues we’ve had, and after almost two years of driving the car competitively, to have gotten 2nd in
qualifying was amazing!!! Gutted that I spun in the final...
I’ve got over a second to find and hopefully once we get the handling issues sorted out we can make our way into the 55sec laps.

Great update and in the second picture you are certainly 'exploring the track limits'

Nice car and thanks for sharing progress. Where did you get your cage done and is it MSA compliant? I’m looking to fit one to my riot and any recommendations would be welcome

Will do thanks, I’m just 5 mins from circuit. I’ll come along to next SLS on 15th June or let me know if you will be there before then.
Cheers
