Good guess tbh mate. I've tried to get in there before, but i don't know what hoops to jump through. How did you get in out of interest?

Its a 197 inlet on a Megane 225 head mate. Different port profiles. The weld is there to strengthen up the flange after it's been machined to suit the 225 ports. That's just how it is when you convert the 197/225 head to run on a 172. The 8mm bolt for the tensioner is in a different position on...

JLR?

I don't have a cut off switch on mine I'm afraid.

More overlap = lower cylinder pressures mate FYI. :up:

@Gerben Visser yeah sport/race cams will affect the dynamic compression ratio. It's all down to the overlap. That's how mine gave a lower reading on Grp n cam timing compared to when it was standard timing. Nothing changed - just the timing.

No mate you only do the oil in the cylinder test to see if it improves the reading. If it does the rings are worn basically.

Did you drop a spot of oil in the bore as well when you did the readings?

@Gerben Visser Technically you have changed your dynamic compression ratio. The compression ratios stated by the manufacturer are static ratios, whereas they dynamic comp ratio is never as high. My Grp n timed 172 engine had lower comp readings and went like a scalded cat. Long time ago though...

Yes please mate! :hearteyes:

Yes please! Lol!

You will have a full guide before you go mate. I'll make sure I've reviewed it for you. :up:

Yeah raychem dr25 is what I used.

Incredible Hulk!! Lol

That looks very purposeful Fraser!

Tbf, they do have some pretty serious machinery rolling up there for a bit of street racing.

Let me know what you think to the AD08's mate. Considering a set as my road tyres tbh.

Yes. Lol

Yet bassetts pole is pretty much left alone! Lol

Is that not illegal in that area now anyway? Assuming it's classed as 'cruising' of course.

Degrease, new bolt, torqued up and fire it up. If it still runs now there's no reason why it wouldn't after you've done the work tbh mate.

Lol! They're not bad at all tbh mate. A damp cloth is what I usually use to get the crap off in hard to reach areas. It's a Hoover for the rest.

I decided to tackle the most hated job I have on the cup today - dash top removal. With the roll cage it's a complete t**t of a job quite frankly, but it had to come off so I could fit the gauge. Removed - fitted gauge - wired in - refitted. Here's a few pics of it fitted. It'll do! More to come.

Has it done it after each rebuild?

What are the engine/gearbox mounts like? What's the condition of the dog bone? It's one of the above - OR its internal in the box mate and it needs opening up again. The springs that retain the selector hub in gear have been known to go weak.

You just need to keep to the right mate. :wink:

No he's not. They're the wrong way round, but it makes no odds to how they operate.

I only have experience of it on the turinis and road tyres on a wet nordschliefe mate, but it handled no different tbh.

Yeah I was impressed with their strength as well mate. I've got to trim the return lip on mine. Lol! They're a bit too close on 888r's in 205/45 16!

It's like trax mate. Just a smaller circuit. Or fcs for that matter. Basically, wheelspin Wayne rocks up with his best trackie on and cap on back to front. Then proceeds to drive his 'slammed (insert hot hatch name here) on sick rimz' at around 94% of his actual ability. This in turn leads to...
