Just got to run the car for the first time and after installing the lower pulley when accelerating spiritedly the SC belt starts to slip and squeal.
Question for the group, will the belt break in and this will stop or is it something else I should be looking at. Tensioner seemed in very good condition taking a breaker bar to pull back.

I have not installed the tune yet. Only lower SC pulley.

 

You may have a belt that's too long. I have a 2016 and VAP did change the recommended belt for my VIN based on a change made by JLR. I didn't notice slippage at first but did once the air got cold and density went up. Check with VAP for your hybrid engine/chassis configuration.

 

Thanks, it is a cool night here. Will check with them tomorrow.

 

good catch @lizzardo . Turns out the engine I got from the junk yard was from a type S. Score with the smaller upper SC pulley. Boo that I didn't know that and so requested the wrong belt.

 

According to VAP, it's not an S vs. Base issue but a change at a certain VIN.

 

Yeah I had mine done about 4 years ago and the wrong (previous) belt was put on, I got it nearly home from the install and it stripped the belt, ended up like a tangle of spaghetti and I had to send it back to the mechanics on a truck.

 

Yep, it's to do when JLR changed over from the "silver" crank pulley to the black one. That's why on the VAP web page when ordering a larger crank pulley one of the first choices/selections they ask you to make is silver OEM pulley vs black OEM pulley, as they are a slightly different shape (one is more offset than the other) and require different length drive belts.
Hard to tell exactly when this change was made but my best guess is some time in 2016.

 

ok, I was asked about the lower crank pulley and confirmed the proper type on the donor engine. Working with Mina Gallery now to sort it out.

 

I have a 2014 V8S. My lower pulley is black. Do you know if the pulley for this year was silver or black. I'm trying to figure out if it's been tuned. App on my phone said I have 600 hp at the crank. Not sure if that's accurate.
Thanks.

for my 2016 with the lower pulley can anyone share what belt it is? getting impatient and want to see if I can find a belt locally.

 

The information I have from my correspondence with VAP is that I now have a "1438" belt. This is the "short" belt, and "long" is 1485. When I originally ordered my kit they included a 1461, but JLR changed the break in VINs and mine is quite close to that point.

Other specs on the belt? There are no numbers on the one I removed, so that's all I've got.

 

I have a 2014 V6S MY 2015 built Oct 2014 and my OEM pulley is silver with a thin strip of black rubber running around it (for damping/balance???), so suspect it would also be silver with a black strip on a 2014 V8S.
AFAIK all after-market pulleys are solid black and with no rubber strip.
Which suggests you now have an after-market presumably larger pulley, but of course I could be wrong and it could still be the OEM pulley.
They only way to be sure would be to measure the diameter of your current pulley and compare it to the stock pulley diameter (which I don't know without researching).

 

Hmm, standard size from gates is 1438MM long.
Gates part number 85501033
Gates® Micro-V® Dual-Sided Belts | Gates Corporation This is double sided though
Gates single sided - K080566HD FleetRunner® Micro-V® Belts | Gates Corporation

 

I plan on doing the plastic to metal coolant pipe swap soon. As soon as they are back in stock at EuroAmp. I will look at it then.

Thanks.

 

The belt sizing isn't to do with the change to the crank pulley, it's a change in the tensioner assembly. It has a VIN break for each vehicle that the engines are fitted to, although JLR themselves have changed what VIN their system indicates several times.

 

Can't speak for other companies, but our pulleys are silver or black depending on the specification.

 

Just to be 100% clear - the title of this thread says VelocityAP Belt Slippage. If you ordered a pulley from Mina Gallery it is NOT a VelocityAP pulley and NOT a VelocityAP belt either.

 

slightly off topic, but if there is slippage due to the older non-griptec pulley (upper) do you guys offer replacements or credit toward the revised pulley? Suspect mine may be in upper RPMs in some conditions but going to do some logging to confirm.

 

Correct, but I can't edit the title of the thread after learning this fact from you. To be clear VAP has been helpful in me understanding the differences even though it is not their product.
And I have asked the Mod's to update the thread title.

 

One of the moderators could edit the title to something more appropriate such as, "Mina Gallery Belt Slippage".
