The only time I’ve experienced something like this was caused by the airgap being to large on one of the sensors. Fine when pushing on, but triggering the abs at slow speeds/light braking.
@banhama have you had it mapped on the bigger throttle body? If you haven’t I’d suggest you get it done. The engine is showing improvements in airflow as it’s potentially increasing the manifold pressure. It may well be drawing more air in, but unable to burn it.
I’ll drop you a pm mate. And the clutch bracket welding isn’t an issue. I can just replace the upper half of the casing when it’s apart. 👍🏻
172 or 182 btw?
Well the 172 inlet is different to the 182, somyou need the 172 inlet with the 736. I’d replace all bearing shells and order standard thickness thrust washers. Main bearings bolts should be replaced as they’re a stretch bolt, but just measure the thread pitch and bolt length - then replace them...
I misread that you’re not using the 182 head. You also don’t have the vvt issue was talking about above as you only have on/off to think about, so easy to map.
I wouldn’t run the ph1 big port head though as you want gas exhaust speed. Ph1 head has far too large ports, but everyone thinks it’s...
All torque settings are as per a standard 172/182 motor as they’re all the same thing.
Order a 197 upper gasket set and a 172 lower gasket set. That’ll cover the bases.
But the issue you will come up against is the vvt. The system in the 197 works in a different way to the 172, so you’ll...
The best way I found to set the pms shifter up was as follows:
Select reverse gear and have an assistant hold the shifter fully over to the left with pressure on.
Undo the collar at the gearbox end and allow the shifter on the box to return to its natural position within the box, whilst still...
My advice is leave them alone. The exhaust cam journals wear more than the inlet and as a result, they then start to haemorrhage oil pressure due to the increased clearance.
Mate don’t even worry yourself about that. It’s only when the journals are heavily scored and you can feel it with your finger nail that you’ve got problems.
Those journals are in very good order for a f4r cylinder head - trust me I’ve seen way way way worse than that.
The exhaust cam always...
Something else worth checking is the tightness of the lower spherical bearing in the housing. Lift the front end off the ground and unbolt the 2x bolts from the lower spherical holder to wishbone. Leave the main nut for the pin tight! With those 2 bolts out, the ball joint holder should move...
Well, yes and no lol. The main thing is, all areas of concern were identified and rectified mate. But there was a lot of head scratching going on in my garage on sunday morning before the culprit was found - and it wasn’t even the actual real culprit of the issue in the first place 😂
I’ll leave...
Gripper is a plate diff with ramps that transmit 100% of the power to both wheels when they lock. The Quaife is a torque biasing diff and it transmits power to the wheel that’s spinning.
Erm..........? When are we booking you in?!
The gripper needs a service after around 2500 miles (ish) if it’s set up for trackdays. Regular oil changes help to extend the life of the friction plates in the diff as well.
Easy way to check the diff as well. Jack the car up and leave one front...
Any decent machine shop should be able to do that mate. If it’s not something that can be done, they should also be able to advise why it can/can’t be done. 👍🏻
