I have a looong way to go to get to Coventry, so by the time I'm back in Scotland I'm already a third of the way there mileage wise, another third doing daily driving, and add the last third from the trip down... 
Just hope the mix of motorway and town driving is correct for a good running in process.
Btw is it actually temporarily rev limited to 3.5K (my daily drive tends to be this anyway), or are you wearing a Ski boot to restrict ankle movement, or sheer will power?
No, the revs aren't electronically limited - am truly sick of short shifting now and having to keep one eye on the rev counter all of the time!

It still revs so freely it is easy to go over. I had always assumed the engine would be less free-revving, based on what I had read, but no.

Your going to be in for a treat if you haven't gone over 3500 revs It still revs so freely it is easy to go over. I had always assumed the engine would be less free-revving, based on what I had read, but no.

When people say 'free revving' I think they are really talking about how fast revs drop/rise when in neutral, or drop coming off throttle. I guess its a feeling of eagerness, but at the end of the day this doesnt amount to much does it? I mean, if the car accelerates faster because there is more power and gearing is the same, then surely this is because revs are rising faster too. What do we call that? 
iirc you have the lightweight flywheel as well? Maybe that is helping induce that 'eagerness' as well. I got one too when the clutch went.
Sounds like you will be having a lot of fun v soon
Now back to looking for much needed cash to throw at this thing...

Yes, it's how fast the revs drop/rise and how the revs rise when the throttle is pressed - so have said it's slightly more 'lazy' like a V8, but I haven't experienced that. It's like the old S6 but better.iirc you have the lightweight flywheel as well? Maybe that is helping induce that 'eagerness' as well. I got one too when the clutch went.

I have Powers' lightweight flywheel, but cannot comment on any difference because I had so much done/upgraded at the same time. I doubt it makes a big difference, though.

Sorry, but it's a massive difference.I have Powers' lightweight flywheel, but cannot comment on any difference because I had so much done/upgraded at the same time. I doubt it makes a big difference, though.

Are you talking about Powers' or someone else's?

is same same as lightened. you can take the standard one and lighten it. will do the job.
you can take the clutch assembly and lighten that too.
hopefully rest means engine wise had been balanced well otherwise soso decission
The racing green flywheel is totally different to the powers flywheel, which looks like a machined standard one. I don't believe You could machine a standard one to the level the RG one is, you'd compromise structural strength. you can take the clutch assembly and lighten that too.

havent seen the RG one up to date...... would worry more about the occuring imbalance when using one Like Don says, it makes a massive difference.

@chris
now i do understand your point as you have a lightend one. if you compare standard flyhweel to lightend one it will
be a night and day difference. my comparisons with engines had been standard to standard.

I've had the pleasure of driving a few big engined lightweight cars on track and road inc a 66 v8 Griff and I also believe that a lightened flywheel can have a massive effect. One such car with an all alloy bored & stroked Ford V8 subsequently had a 'skeletal' alloy flywheel and small 7" triple plate clutch fitted in place of the somewhat huge steel affair that normally carried a full Mustang sized clutch assembly and it dramatically changed the driving characteristics imho. Pick up at any rpm was much much sharper and deceleration also was markedly different.(improved!)
It was eventually a bit of a pig to drive on the road in traffic though, as the clutch was almost on or off in operation. Too few revs and she'd stall, not even labour and a few too many and she'd leave big black 'II's all over the place. between 3000 & 7900 she was a beast and was still the best to drive on track (esp on wide slicks).
Congratulations on your conversion - sounds a blast. !!

Not particularly worried, out sourced rotating assembly balancing to Julian Godfrey Motorsport @chris
