You're on about fixed 3 point harnesses, not inertia-type belts like in production cars (doesn't really apply to our types of cars) right? I get the focus on racing/etc but it's not something the average joe on the road really needs to worry about. In our types of cars, you have to be pragmatic for the general types of users we have; I guess 95% of sales are to road users. An inertia reel isn't practical because of the car design (you could get the mount up on the rollover hoop, sure, if GBS were that way inclined) but I'd probably err more on the side of strapping myself in so I don't come out. Submarining or not, I think if an impact was that serious in our little tin cans you'll be waving goodbye to your legs pretty quickly, whether it's a 3, 4 or 20 point harness :). A frontal is probably not too bad because there's a heck of a lot of front crumple (ie. the entire chassis forward of the bulkhead) but anything remotely side-on, or something that splits a chassis tube and had it poking into the passenger compartment.... I think the least of your worries is "damn it, I wish I had a crotch strap to stop me sinking forward" Just wouldn't want people worrying over nothing, or at least putting it into context. The guys who popped their testiles out thanks to a 6 point are probably very annoyed about it, sure, but I bet they're glad they were wearing something more than a 3-point intertia reel !! edit: I should say, you're totally right, a badly-adjusted harness is going to do next to nothing, and at least that's the one good thing about a 3 point, it's less prone to incorrect adjustment. I have an issue with the GBS/TRA lap straps, they constantly loosen, I was speaking to TRS at Autosports about swapping my harness for ones with reversed lap straps with motorsport adjusters on them... bugs the hell out of me

Can you elaborate? I get the anti-submarining idea of a 5 point (although I'd argue for a road car we're getting a bit over the top), but 3? How is it better?

They're typically used on wire rope/cable for suspending fixtures and fittings. I think if you search around that you'll probably have more success. Quick google : https://www.tecni.uk/wire-rope-fittings https://www.tecni.uk/6mm-Stainless-M8-RH-Jaw-Tensioner-Fitting-160.800.060

Me plus 2 please!

In my experience most Emerald maps I've seen are very conservative on the startup fuel map and enrichment. Assuming your throttle bodies are all balanced and in correct adjustment, I'd look at the startup enrichment and also the ignition map. I'm sure you'll be happy fiddling around with the laptop making a few tweaks here and there ;). A good way to see if it's that is to just up the fueling on the base map temporarily at the startup load sites (zero throttle, <1500rpm) and see if it suddenly improves... obviously don't keep the changes, but at least you quickly prove it's not getting enough fuel. Otherwise do the same with the ignition map. Given your location, if you get real stuck, you're welcome to meet up and I'll help

I would love to but looks like we'll need to spend the weekend prepping a house for tenants play it by ear with us but make us an "unlikely"... sorry

If you get really stuck/GBS won't sell you one.... https://www.aluminiumwarehouse.co.uk/aluminium/channel

Back in the warm here too! Car wash can wait until tomorrow <brrrr>

Bell/text me in the morning if you like, if it's just the two of us we can wing it there and then and figure out where we're going....

I'm up for a little run out - can't be too long, say a couple of hours maximum... run out somewhere for lunch and back?

We have noise tests to adhere to when competing and these generally state 100dB ~ 4500rpm, half a metre away from the exhaust tip (45 degrees). I don't know how sound dissipates with distance, obviously it does, so I guess that 74dB is a kind of pointless number without the context of distance being applied. "What did Europe ever do for us" etc etc <joking, before you all get on your Brexit high horse!>

My motorbike is 100dB and that's on the manufacturers exhaust !? WTF?!

Yeah, definitely not a 2B; looks like a Mk.1 S7 (sierra based)

Yup... https://www.rhocar.org/index.php?showtopic=41972&p=335327 Not sure if he's still around...
