Astra VXR Nurburgrin
Love the car. What race are you entered in? I wanted to enter time attack but would prefer actual racing against other cars rather than a clock.
I couldn't possibly tell you that! It's not gonna be a massive money build. I need a spare engine anyway as after whats happened to everyone else's this year I'm thinking mine is living on borrowed time! So I could build up another the same spec as my current lump but I might as well make a few tweaks to it while I'm building it and it's in bits anyway. Light weight and reliability is what I'm looking for, things like a 197 bottom pulley and proper key-wayed cam pulleys to stop the timing slipping little improvements like that.Any hint's on the spec of the engine build Russ?
Seems like everyone is adding power for next year.
Is the 197 crank sprocket keyed? I know you can buy a 172/182 keyed crank pulley from ED, Pauls crank sprocket slipped at snett (not heard this happening a lot) that seriously damaged the valve train.
Is doing away with the VVT an easy job?
No it's going track only, fancy racing in the Tricolore ultimately but I'll have to assess my budget in the new year and make a call.If you know a bit about cam timing then yes. Wouldn't recommend it on a road car though.
197 crank I've got has a key way on it but it's a simple machining job if it doesn't.Megane crank sprocket is def keyed and it a direct replacement, providing the crankshaft has a keyway, 99% of them do but a small few didn't. Not sure about the 197 crank though.
The f4r is a pig to dial the cams in on due to the cam cover holding the cams into the head as well. You need to be able to access stuff and get the dti in there to do it properly and the only option available currently is the catcams kit.If you know a bit about cam timing then yes.

They'll work with any as you have to drill the end of the cam to accept the dowel.I think the catcam ones are doweled too, hard to make out from the pics. Do the piper pulleys work with catcam camshafts?

The catcams kit just holds the cams in place and allows them to be timed in as there's no cover there at all. At the horseshoe end there's a adjustable horseshoe that allows you to then replicate the desired cam timing position with the cover on.How does the catcams kit work Mark?
I have an old cam cover with holes cut in that I can use to dial them in but you still have the problem of getting the proper cam cover back on and to do that you need to remove the pulleys from the cams again IIRC. I was thinking I'd get an old horse shoe, cut it in half and make some sort of plate to fix it to. I could then take a reference of the timing that can be used to get back to the dialed in timing when you put the cam cover back on. Is that how it works?

Thanks mate appreciate the comments.Just read through this entire thread and watched some of the video's. Very inspiring stuff and a good insight to racing a clio. Will keep an eye on this going forward
I can get it somewhere near with the equipment we've got but normally have it done at the start of the season properly by Blink and if i have it in bits mid season i'll get them to do it again. They've done it twice this year and then i had to do it roughly after cadwell myself. I do take the geo seriously as it makes a massive difference to the car.How often do you have the geo setup done? Everytime you remove or mess with the suspension? Or do you set it back up yourself?
