The pulley should be a straight swap, but you might need some heat to get them changed over Sent from my SM-G950F using Tapatalk

Am I right in assuming we can press off the old one ? For refit was thinking the new one needs to be heated up in oven (say 180c) and then tapped firmly home. Sound right Vocky ? Sent from my SM-G903F using Tapatalk

Is there a thread down the center of the shaft ? Sent from my SM-G903F using Tapatalk

You can pull them off with a press or puller, heating the replacement in the oven is ideal. Remember to wear gloves and be quick. Sent from my SM-G950F using Tapatalk

Hopefully the shafted relay did not put to much heat in the engine, and warp something.

When my relay stopped, the intake temp skyrocketed very quick. I monitor it via my phone and torque so was quick to stop the car before it could do damage.

I found even heating the pulley hub up as much as I could in the oven, it didn't go on easily, and required a lot of force to try and drive it on. Therefore, I'd try get some kind of contingency bolt to drive on the pulley.

 

The worst case is that the hub cools part way on, and becomes very difficult to budge.. I found the Smoothflow hub to have a very tight tolerance, and therefore not easy to install.

Shouldnt have caused any damage, when IAT's go high then knock is caused which is picked up by the ECU and timing is retarded, net result is a drop in power but no damage.

 

More worrying for the engine is the coolant which now resides in Neils intake manifold - hence we have not started it since realising where it is going.

No they are all really tight. Haven’t got correct screwdriver head to remove. Will try local engineering place for bolts

 

Hawk Fasteners in South Bank, they have almost everything.

You could also try packing some bags of frozen peas around the shaft (as well as heating the pulley).

Thanks Nev good idea. Sent from my SM-G903F using Tapatalk

Update. Spent the day at John’s yesterday. It’s all coming together. So replaced and re situated the charge cooler pump relay in an easier to reach place. I’ve a feeling the charge cooler hasn’t been operational for a long while so it will be interesting to see how my intake temps are on track with the WI now. Replace all the o rings on the laminovas with quality items that John specced and they fit snug! As my giant foam air filter had come apart from it base on John’s recommendation I’m going to replace with a Saab one from the 260bhp 9-5. Nice and oem and fits well. I’ve got the front lights here to reseal, we need to top the gearbox oil up, fit the 3” pulley and put it all back together. John has helped so much it’s embarrassing. But without his help I would have been selling the car for parts. Sent from my iPhone using Tapatalk

Should also say that we discovered a small split in the charge cooler hosing that won’t have been helping. Luckily John had some lying around that could have been specifically designed to fit the space so that’s another thing sorted. Sent from my iPhone using Tapatalk

Looks like you found a good one in your helper acid

Had I known the scale of the issues then I may have thought again. Sadly I cannot unsee things that are wrong, not working or out of place. OCD kicks in and I have to correct the issues, there were lots to correct. Sent from my SM-G903F using Tapatalk

Question - will I need a smaller SC belt now I’m changing to a 3” pulley and if so what size? Sent from my iPhone using Tapatalk

From what size? From the standard 3.35" pulley, almost definitely, or you will get belt slip.

 

It depends slightly on a few things, but around a 1270 - 1275 belt is about right for a 3" pulley.

Yes from standard pulley size cheers for that dude I’ll have a look. Sent from my iPhone using Tapatalk

Presume we will need to extend the pressure range in the Dutch due to more boost Standard is 0.9bar ? What will this produce on the 3" pulley ? Sent from my SM-G903F using Tapatalk
