I would have thought that you could see sixty in a little over 4 secs, but that is purely a guess.

My 0-100 isnt great because I currently need to get into 4th to get to 100, with lower profile rear tyres I should get to sixty abit quicker.

Cheers

Yer I am also pretty sure I can get the 0-60 down but need to practice, like I said in a previous post lower profile tyres are gonna help as well when I come to change mine for the 225/45 R13 R888's.

I have been doing some research on gearing and I reckon I can get to 100mph in third which should shave a load of time off. I got my gear ratios from HERE (K-Series, RSX Type S K20A2 is the gearing) and then put my tyre and wheel info into HERE. For everyones info that cant be arsed to go back through the build diary the rears are 205/60 R13 and the final drive is 3.9.

The gearspeed program only goes up to 8000rpm but working it out I should get exactly 100.12 mph @ 8800rpm so next time I am out on that same bit of private road ;-) I will try resetting my maximum recalls (SPA speedo records maximum revs and speed all the time so if you set a new high speed it will then be available next time you press the button for max recall) getting it into third and seeing what the max recall is when I stop. if it comes in at 100 mph like it should then I will re-try for the 0-100.

I am waiting for the next dry weekend to try and get some footage of the car in action and hope to be adding to the lonely video I have on You Tube curently.... keep em peeled.......

Awesome build......

Just out of interest, how much does something like that cost to build if you don't mind me asking, because I have spent an arm & a leg on mine and its

nothing like yours...

Thanks.

I have spent approx £35,000, I say approx because its somewhere a bit over that mark.

When I look at that amount it makes me shudder as other than the house I live in thats the most I have ever spent on a single item, well lots of items becoming one. I couldnt have afforded to do it without releasing equity from our property and now I am back to being broke again, just in a lot more debt than I was before. Even more unfortunate was that it took the death of someone close to me to realise that we are only here once and life is to be lived, even if that means living it at break neck speeds - yee haaa.......

Yesterday I decided to go out for a run with two of my mates (they were on sportsbikes so I didnt have to wait around for anyone). As my photoshoot for Miniworld is coming up soon I was going to leave it in the garage but damn it was nice yesterday so I had to go..

With the photoshoot in mind I hadnt yet done any timings for the car and as my SPA speedo gauge allows me to do whatever timings I want I thought I would give it ago. So I found a nice flat and fairly smooth bit of road (private road of course :) ) and then first I set up for my 0-60, then 0-100 and then 40-60 as these are the most talked about numbers. I hasten to add at this point I have my speedo calibrated to within 1mph of my GPS speed camera locator so its pretty frickin accurate.

The Results:

0-60 = 3.4 seconds
0-100 = 8.0 seconds
40-60 = 1.6 seconds

I only had three or four attempts at the standing starts and the 40-60 is just from one run and needs a few more runs to see if I can get it down with different gear selection. The standing starts were done taking off in first, minimal slip, no wheel spin, drop it and go. I reckon I can get both times down with practice and a clutch I didnt care too much about, still there not bad for an amateuer......

Car is now off the raod for a cleaning session ready for the photoshoot, so keep em peeled for the article in Miniworld sometime in the future.....


Brilliant figures, ive been watching this for ages now its amazing.

Keep us posted when the mag article is out.

Thanks Rick

Its frustrating currently as the weathers so rubbish that I cant use it as much as I would like. I did go out in it the other day when it looked like it was going to be dry but the roads were still well damp and it is somewhat lively on damp roads, only if you push it, if you drive normal/sensible then its fine. Just if you gas it too ealry on a corner it'll snatch round a bit, or away from the lights and it'll twitch sideways. Great fun though and a good experience.

WHEEL FAILURE:

So my run of good luck with the car came to an abrupt end with a POP and a HISSSS from the rear O/S tyre on the weekend, with what at first glance looked like a regular puncture. Fortunately I was only doing about 50mph round a long sweeping bend (hardly any lateral g-force) and was able to bring it to a controlled stop.

I friend was passing and collected me, we went and bought some tyre wled with a view to it getting me home, but two cans of that didnt work, Del then went off and got a bottle of nitrogen at 50bar and we tried pumping it up with that, the tyre went up and then straight back down again, at this point we noticed the tyre weld solution coming out the centre of the rims as they meet the centre wheel part.

I took a closer look and found one of the twenty bolts that hold the wheels together to be loose, so I gave it a jiggle and it come out in my hand, I then put my fingers through the wheel to check the nut side of the bolt to find that 7 of the bolts had snapped. These aren't monkey metal bolts either, they are 12.9 High tensile bolts.

Anyhoo, I have loaded some pictures below for you'all to have a look, I have emailed Image Wheels with the photos and await a reply, I will keep you posted on that.


So here are a few snaps, firslty of the car with the flat, one of the wheel on the car and the rest of the back of the wheel:

Ouch, that does not look good at all! Hopefully image wheels have something to say! Glad to hear you managed to catch it before it got any worse...

Been in contact with them and they are being good as gold, I think I am going to fix the wheel myself and then double check all the torque setting on the rest of the wheels. Harry at Image has explained how there production line is unable to overtighten the nuts and that they order the bolts in the hundreds of thousands and they havent had a bolt failure before.

It'll get fixed and thats all that matters really.

I am gonna chalk it up to an unexplained.

I know what you mean but you get to a point when so many things have gone wrong that you just take them in your stride.

It's called acceptance. Stuff happens and you can't change that it did, but you sure as hell can fix it!

It's a lot easier to listen to someone's problem when they are not shouting down the phone >_<
