The outlet for that traction fluid line, is it free of kinks and stuff? It looks like it could be in that one pic.

The kit does come with a restrictor. It is the black circular thing next to the pulley in the kit overview photo further up. It is required to have the restrictor fitted, for the kit to be legal in Denmark. Somehow I must have forgotten to put it in. Let's hope I don't keep forgetting it

I haven't done any boost leak testing. I'll try to make a tool, and get it done.

You're right, in one of the pictures, the outlet hose looks squashed. That's not the case, there is a nice gap between the charger and the bracket

Any chance your belt has become glazed? Or your pulleys?

i took off the belt to check. This is how it looks after 200-300 miles

That looks very worn, doesn't it? Almost like the teeth have been ground down.

I've indicated the belt routing in this photo. Note that the three center pulleys are flat, and the belt runs teeth in on two of the three pulleys. That's probably not ideal, but would it cause belt slip? I've also indicated the tensioner direction with an arrow.


Any suggestions?

I have no experience with this, but maybe switching the bottom smooth pulley with the center ribbed pulley would help? Just a thought.

All three pulleys in the center of the photo are flat. Only the charger and the crank pulleys are ribbed.

That might be part of your problem.
Flat pulleys are OK on the outside of your belt, but not really on the inside I think.
The important thing here is belt tension: you need tension to prevent the belt to slip.
I am afraid the flat idler pulleys sort of squash the high ribs of the belt and prevent you from getting proper tension.

without any prior knowledge, that sounds right.

I have tried changing the belt routing by rotating the mounting of the tensioner, so the tensioner movement is more downwards. Illustrated here.



This setup also doesn't seem to work, since the tensioner doesn't move sufficiently down to take out the slack, even with the shortest possible belt.

I'm lost here. Help.

If it's a cheap hose, a stock Miata at idle will collapse a silicone inlet. My old MP62 setup used to do it. I would hope the kit the OP has included a quality hose.


Something's really weird here. Did you buy this kit new or used? It almost seems like the bracket and tensioner system is not compatible with your setup...like the kit is for AC or No AC and you have the opposite.

Do you have proper check valves on all the vac lines? Could have one going bad that burps at ~6.5psi

Also, what kit is this? Every other one I've ever seen has the SC mounted significantly higher, plus I notice the one tensioner pulley in your system seems to be a good 6-7cm below the main crank pulley...

All the charge tubing and intake are silicone. Looking back over this thread, I'm still sayin its those hoses collapsing at 6000rpm.
