Cheers people. That just about clears it up. By the way, just for the record, I was aware that the Vtec system of a second cam differs in concept from the variable valve technology, I just wasn't aware that the VVC operates over the entire rev range - if I've understood it right!

My Girlfriend's sister bought a hairdryer, sorry, an MGF VVC, a few months back and her new boyfriend drove it at the weekend and said it didn't feel or sound like the VVC was working. She doesn't know what VVC is.... I have an Integra with the Honda Vtec system and the second cam makes a huge difference - you couldn't possibly miss it. Should the VVC feel similar? And, if it's not working, is there a cheap fix? Help please

😬 thanks guys

I have a Honda Integra Type R and have noticed that the second cam doesn't seem to come in if the engine is cold. Is this normal? Is there an explanation for it? Or is there a problem with the engine? By the way, I don't normally rev the engine when cold, but have done so twice now and noticed it both times. When hot, the second cam kicks in perfectly.

ha ha ha, sorry Nifty, ten thousand apologies! 😳 😳 Still, looks like Richard's not biting! I don't get it!?

nice try Ernie 😬 Try 2015...

Sounds like the ideal car to replace the SL I sold last year, eh Nifty! 😬 Must check those Wednesday Lotto numbers 😬 ............damn, only 1 number.... ☹️ ☹️ I guess you won't take a packet of Jaffa Cakes instead Richard??

*confused*Crumbs..... So, really, the answer to my question is to run whatever octane fuel the car's engine was designed to use: in this case 98. 🤔

Strange that AVGAS is so expensive then, especially as there is cheap diesel for boats and agricultural vehicles. What do formula 1 cars use then? Isn't that very high octane stuff?

Thanks Peter, that's interesting stuff. Thinking about all this 'RON' stuff, led to me recalling something I read in a book about D-Day, where a pilot (I think) was saying that the Aviation fuel they were using was only 97 octane back in WWII. I may have misheard, but it certainly surprised me whatever the figure actually was. It seemed very low. Is that likely?

Thanks, thought it might be

I filled up with SuperUnleaded at Sainsbury's this morning (OK, I just wanted to buy one of those breakfast packs!) and noticed that it's 97 octane. My [says quietly] Integra Type R has a sticker on the inside of the fuel filler cap saying that it needs/prefers 98 octane. I was wondering whether I should stick to Optimax (I usually do) but wonder what octane rating it is? Can anyone remember? And, by the way, yes I do hope to buy another Se7en soon!!!

According to the Caterham internet site, it's a "Wheel 7 x 13 Minator Black"

Crumbs, now you're asking...Um, not sure. It's got a black rim with silved inside, with black spokes (from memory). Does that sound normal?

Yep, just one wheel, shod with a single tyre. Both were almost brand new when bought as spares, neither used since. The wheel looks grotty and needs restoration (darn thing was new but was left in a damp garage! ) Tyre looks like it's done a few hundred miles only. Anyone want to offer me something? I'm in Suffolk.
