I know they are about 8kg each compared to stock 10 to 12g without tyres am guessing
Stock wheels are 9.695kg (according to Mazda). I'd like to see someone weight a PZ wheel, because I'd be really surprised if OZ managed to get it down to 8kg. That would be exceptionally light for an 18x8 wheel.

That’s 3 years and 7.2 months right?

Surely that depends which month. I'd say it was 3 years 219 days, but 2016 was a leap year so I'm not sure how that should be factored in. Come on Eddie, we need to know. :?

Re: supercharger centrifugal

Yes, you're both right. But I don't think the situation is dire. It's due to an advantage a Rotrex has over a turbo; A turbo can blow 15psi or 20psi (or whatever) at 3000rpm, and control this level of boost all the way to peak revs. It therefore generates hot compressed air all the time, and an inte...

Re: supercharger centrifugal

Back to some sums. As mentioned before, the Rotrex could, in theory, boost to around 2bar (absolute), or about 15psi gauge at high revs. In theory that could give you over 470bhp, but a supercharged engine won't really make this much power. One of the key reasons is that a supercharger consumes powe...

Re: supercharger centrifugal

Sorry, I should have said, my boost numbers are absolute, not gauge. Your 1.3bar will be gauge, which is 2.3bar absolute, which is loads. And the fact that yours makes it from 3300rpm is what makes turbos so...... :twisted: (Compressor maps are always done as pressure ratios, which is basically abso...

Re: supercharger centrifugal

I decided to look at the kind of power curve that a Rotrex could give you. Firstly, it's important to understand the difference between the various boosting technologies: 1) A screw-type supercharger is "positive displacement", so will force air into the engine at low and mid rpms, but at high revs ...

Re: supercharger centrifugal

I've been having a look at the compressor maps. I think the Rotrex would be a great solution. For safe low end torque a C30-64 would do. It would make about 290bhp at about 5500 rpm and 15psi. It would choke off at higher revs. For stupid power (and an exhaust full of apex seals) the C38R-112 would ...

Re: Identifying/loosening alignment fixing nuts and bolts

It's the bolts that seize. The nuts usually come off fairly easily. The bolts need to be free to be able to do the adjustment. My suggested process is: - Wire brush the loose rust off the bolt threads (it's amazing the difference this simple step makes) - Firmly (but without damaging the threads) ta...

Re: T200 CAD Supercharged RX-8 Engine Renaissance

Mine is obviously very stiffly sprung, and it's super-sensitive to any wheel imbalance. So it could just be because of your suspension setup. One easy thing to check. Look at your tyres, and check they are correctly seated all the way around. You will see circular markings on the tyres, just near th...

Re: Armourall headlight restorer - don't use!

The headlights are polycarbonate, which is inert to almost everything. It would be very hard to find a "normal" chemical that would damage them.

They are just the same as all the other "Power Flex", "Strongflex", "Floflex", "Polybush" kits out there. A bit crude, and only really of use on a race car. Also note that those MRP bushes don't come with inners. You'd have to chop the inners out of your current bushes, clean them up, and fit them i...

The s1 bushes may well be the same but (if I recall correctly) the ball joint is different, so the s1 arms don't fit an R3.

If cruise control is a key reason to choose the R3 then you might be surprised to find that it can easily and cheaply be enabled on the s1. If you join the Club you will find all the information you need to do it.

I'd swap your tyre round before worrying about your uj. That's exactly the sort of symptom that a reversed tyre can produce. (Even if it's a rear wheel it can cause pull to one side).
