Nick is keeping quiet about his times - they must therefore be either very poor or he is being modest. Come on Nick, how did the new engine go? Also noticed the air scoop has gone so your dad has been busy again. Geoff

Yes well spotted Geoff.
We realised during the Curborough test day that the intercooler wasn't doing what it was supposed to do, so we ran a couple of laps without the nose and bonnet and it was noticeably more powerful. It was the same on the rolling road, no bodywork and a massive fan blowing on the front gave us 189hp.
So at Curborough and without doing any research we hacked a hole in the nose right in front of the intercooler and made a hardboard duct to feed the air directly into the intercooler, that must be better, but it wasn't.
A bit of Googling when we got home showed some wind tunnel images that pictured a blob of high pressure air right on the nose but over the bonnet it was a lower pressure area, so expecting air to enter our new opening was completely wrong thinking.
The upper opening has now been filled in again and a new opening cut into the nose lower down, you cannot see it in Rogers pictures but it is just a slot above the radiator intake in the nearly horizontal part of the nose. Inside the nose the air is now divided between what is going to the rad and the new supply to the intercooler, interesting stuff all this. It made a big difference at Goodwood with intercooler input temps above 40 and output just over 20.
In one of Rogers pictures the bonnet is lifting a bit at the front edge so somewhere about there we need to make an opening to let the hot air out of the rad and intercooler.
I will leave Nick to post his times but we had a good day, cut a bit short by a Honda S2000 having an off https://www.youtube.com/watch?v=5ZSXjM5VWKo

Sorry to have left you all hanging...

Great pictures Roger, was good to see you.

Practice at Goodwood is two laps back to back - on lap one I caught up with the car in front, which was having technical issues, but he peeled off into the pits at the end of lap one giving me a clear run for lap two. Unfortunately they only time the 'out lap' and as i was bunched up behind someone the time keeper didn't note my time.

The event ran like clockwork, so first timed run before lunch, 104.15s; I was pleased with the time but felt it ought to have been better. Speed along the straights was higher than last year - but the time didn't reflect that!

T2 after lunch, this run was much better, making an effort to carry more speed through the bends, and faster on the straight. Time was 105.somthing.... queue much head scratching! How was is slower!

After all cars had finished T2 I was informed that as I'd caught the car in front and crossed the line only moments after him (rather than 10+seconds) the time keeper had 'guessed' when I had crossed the line, so my time may not have been accurate and offered a re-run.

T2 re-run was tidy, albeit I put it into neutral by mistake and fluffed a gearchange. A new PB of 101.6seconds. Certain there's room for improvement there too. 33/90 overall, and 0.22s off a turbocharged RX8.

Based on gearing and revs i was getting 125-130mph on the lavant striaght - almost flat out in top.

More to come next year!

Flat out in 5th? Nice work 8) ]

Sounds like a sub-100 is within reach then - cracking work by Team Keyser!

I can assume you're now getting used to the hike in power?

Well done Nick, not quiet the exclusive 100 sec but much better than last year and ever so near. You are obviously getting the hang of Goodwood!
I see Corky is also threatening to go to Goodwood so perhaps next year we could get a good turnout and give you some competition on a proper fast race track.

Done OK I 'spose.

Time to stiffen up the back end? Looks quite squatted under power what with all those extra ponies and torques.

Well done Richard on filling the letter box back in so promptly. I was a bit surprised when the DIY occured at Curborough!
