Aha, she lives!

Loving the wheels too. They look a bit Comp MO ish, what are they?

Rods saff is pretty nice, but the new reyland escort is a much more inovative in engine tuning, should do 200+ at brunters as well.

Stunning... 8)

 

Bet that's gonna be a little lively to drive... :D

[Scruffythefirst 0]

Turns out its a bit of a pussycat to drive, took it for its tracking and camber setup and it has loads of grip and only lights the rears in 1st with your foot all the way down.

 

Quickish tho, need a bigger turbo i think

[billinjah 0]

[Scruffythefirst 0]

I'm still picking the flies out of my eyelids and the muddy puddles outo of my hair :lol:

 

 

 

Edit: and I've got that pic your dad took on my phone, but no lead to transfer it with at the mo - will get it up next weekend.

[dinkus 10]

And here it is...you look a bit worried :lol:

[bcstudent 0]

So the SVA test went well?

[Scruffythefirst 0]

Sva test went really well, only failed on the speedo (which I knew wasn't working before I left) and a few minor things, like labels for warning lights etc.

 

Trouble is they've all buggered off on holiday and I can't get a re-test untill the 12th. Good news is it goes nicely though, all the way upto the speed where you can't see.

[CoxyLaad 0]

feck me the track is really wide on those things isnt it

looks a good couple of inches wider than a standard seven - could be an illusion though?

[dinkus 10]

Aye, it's a wide boogar :)

That's excellent news, congratulations :thumbleft:

Yup, standard sierra driveshafts - the widebody westys have to have them shortened, and the offset of the wheels onthe dax make the track wider too.

 

Probably why its so lardy - 752kg with a full tank and me in it.

Had the Dax mapped at dave walkers Emerald in norfolk. Turned up at quarter to 10 and was greeted at the door by dave. We discussed a few things and got the car on the rollers. Dave got the idle and light throttle sorted after setting up the basic settings I'd missed. Dave did the first power run at 80% throttle and we got about 220Bhp although it was reading 280 (dyno set on the wrong setting) The next power run at full throttle and there was an almighty bang at 6000rpm and sparks flew from the front of the engine, which died like a stone. I was really worried that the engine had siezed, this was made worse when we tried rocking the car in gear and it wouldn't move - whoops wrong gear Embarassed the engine wasn't siezed so we tried it on the starter but there was no speed signal, and we discovered the trigger wheel was completely unattached to the crank pulley. BUGGER.

 

 

Into the shop and the car wouldn't fit on the lift so out with the trolley jack. I manged to get the crank pulley off after much swearing at a 3 leg puller. The welds holding the steel timing wheel to the cast iron crank pulley had let go, mashing it. Dave was an absolute star and got the whole lot cleaned up and drilled and tapped equally spaced round the edge of the pulley with a milling machine and bolted up tightly with countersunk bolts and loctite. I suspect you might see something about it in PPC.

 

Back on the rollers and the mapping completed and all sorted. We stuck with the current boost level as its mad enough at the moment, but we couldn't go any higher anyway as the amal valve needs re-jetting. Got 236bhp @ 6541rpm and 218ft/lb @ 4388 rpm so well chuffed with that seeing as I built it myself. Got a fair bit more there with only half an hours work if I want, but that'd be silly, wouldn't it Very Happy

 

Dave was absolutely fantastic and very reasonably priced, even without all the work above and beyond the call of duty.

well done! must be a great feeling driving something you put together yourself and know inside out. Its been a very interesting thread to follow and i'm pleased you got a good result at the end of it.

[s.g 0]

congrats mate , well done :thumbleft:

[Kevin Bacon 5]

Excellent!! One of my fave cars on the forum.

 

That's a damn impressive car for a home build mate, you should rightly be proud of your achievement. You're very modest!

 

Looking forward to a spin :-)

 

752kg isn't lardy, well, I suppose it is compared to a Caterham R500, but heck you've still got 313hp per tonne!! The all new 911 turbo can only muster 304hp per tonne, so you can kick one of them quite nicely 8)

Oh dear...whats happened?

[Scruffythefirst 0]

Throttle pot disintergrated. It'll idle, but thats it. Fortunately had the laptop with me and could diagnose it, otherwise it'd be a real head scratcher. Phone call to the RAC was fun - "just send a flatbed i've broken it again"

 

Unfortunately sams clutch went just as he was leaving but as he live just up the road he hitched a lift :D

Dohh! not fun!
