Chris's 172 Cup Turbo

[Bmac]

Just be mindful of the post cat sensor. Mine was fine, then this weekend I fitted a new exhaust which has made the cat sit higher, that and pulling the engine forward has pushed the post cat sensor into the heatshield and gear linkage which then blows the fuel pump fuse when it shorts. Now I need a new sensor!

This worked for me also on my cup,losen engine mount and pull engine towards you and then tighten.I think its exhaust that knocks on the bulkhead.

Thanks all. Have tried and tested yet, but, I did manage to move the engine forward a fair bit yesterday.

Also had a chance to photograph top mount setup. Does all look correct?

These are the top hats. The nut appears to spin on one of them but is fixed on the other. No idea if that’s correct.

I’m sure that it’s separate to the knock and hopefully the engine position is the culprit. Will try tomorrow when the weathers improved.

Looks all good to me. Obviously, I can't see all of it, but I assume this is how it's assembled.

Yes from memory, this is exactly the setup/order. I didn’t realise there were two types of top mount until researching this past week.

Every 172 I’ve owned has already had the updated design without the spacer but. Cheers

So, i've taken both shock absorbers out, and unassembled both. The passenger side spring looks like it had been compressed to the point that the bump stop had split in two. Should the spring be compressing to the point that the coils rub together? (pic below)

Measures taken so far to try and cure this issue:

- New top mount bearings
- New upper gearbox mount
- Polybushed dogbone
- Swapped to OEM dogbone
- Swapped back to Polybushed dogbone
- Triple-checked steering rack bolts are tight
- Moved engine forward and tightened down the engine mount

Knock is still there. I will be booking the car in to be looked at by a garage... although I am wondering if larger outter arb bushes would help? mine look almost loose. I ordered 23mm outter bushes for reference and the arb on the car when dismantling looked to be new/recently swapped.

Bumpstops always fall to bits on these, as they are used as secondary damping when lowered. I destroyed a bumpstop riding the kerbs at Blyton.

Id imagine the springs are progressively wound so will touch coils a bit.

Wheels off and get at it with a pry bar of at home, you'll soon see something that's loose, much easier on a lift obviously if you can get the use of one

Turns out I was looking in the wrong place. Got my brother to take it to work. The ball joints where the incorrect type, and where moving separately from the arms. Not great!

It’s ok now, however, I’ll likely get some second hand Cup arms as spares just incase any wear occurs again.

In the meantime, I finally got some ramp pictures. Nice to see it from afar, rather than on the floor 🤣

Still a few bits like heat shields and trim to put back yet. When I can be bothered

Not much to update, but I've booked Snetterton for the 13th of August which is exciting. Took the car the scenic route to Birling Gap yesterday - the car was faultless.

No real plans to change it up with mods, other than getting the alignment dialed in properly with AW Motorworks in late July.

Cosmetically speaking, the car needs some love. I don't know if it's immediately visible here, but the door is not the same shade of Mondial blue as the rest of the car. The headlights are faded so will be replaced. The drivers side side skirt is also battered, so I need a new one of those too.

Jobs still to do:

• Replace headlights
• Replace drivers sideskirt
• Replace Aux belt
• Oil change before Snetterton
• Camber shims on the rear, camber bolts on the front
• Fit 172-cup door pillar badges
• Buy a new stainless exhaust

The list seems to never end, but I'm determined to just enjoy the car for the summer first, having already spent what I paid for the car and then some!

Epic.

I’ve done the same (spent more than the cars worth and then some) 😂

Poverty friends

Something I’ve had planned for a while; finally getting married after 15 years.

Naturally, after 5 Cups during that time, it seemed fitting that this one was the wedding car 😂

Got Snetterton booked for August and alignment booked in for 27th of this month.

As it was the big day, I tried to get the car looking as good as possible. So fitted some new headlights. Definitely helps make it look a little more cared for.

Long term I’ll retire the car from track duties and use it as a well cared for example on the weekends - respraying bumpers etc. Hopefully a track oriented 250/R26 will be on the cards.

 

[Matt Cup]

Car looks well. Congrats on the wedding too.

 

[Colin-S]

Congrats Chris! getting married to the Cup...I mean wife

 

[bowen86]

Many congrats to you and the Cup. You both look so happy.

Super clean as always.

Was mentioned in the speech. "I'd like to thank my new father-in-law for letting me marry the love of my life..... for those that haven't seen her, she's parked outside with blue ribbons on."

Got people laughing 😂

Took the car to see Alex at AW Saturday last week to get some camber dialed in and the alignment sorted - I'd been driving with the steering will pissed the entire time up till now.

He fitted some Eibach camber bolts and got it to roughly -2.5 degrees. Only 1 shim was needed at the rear drivers side to get it fairly square.

Oh my, what a difference it's made. For a relatively stock suspension setup, it's absolutely sublime on the road. No doubt it will be a little soft on track, but we'll see in a few weeks time!

Proper geo makes such a huge difference huh!

Huge. Like a totally different car now.

Did Snetterton on Tuesday. The car was mega. Reset the trip computer before setting off, and managed 340 miles in total.

130 mile journey to the track, topped up the car to full with £26 from the Esso outside, and then did the entire day and drove back on one tank. What a joke

By far the best Cup I've ever owned (so it should be!)

Everything feels so tight and sharp. You really know where you're at with the chassis.

Will be on the hunt for some 15" wheels and AR1's for next year. Also fancy a diff, but would rather put the money toward a Meg.
