Re: Ceramic CATS and CAT recommendations

It has to be said that I can't think of any other trader who would start an open discussion on products they sell, then also recommend products from competitors! There are some great options out there, and some terrible ones. But if you need a cat then the place to start is surely RRP. Everything th...

Re: Ceramic CATS and CAT recommendations

So do the FIA have some minimum requirements for emissions ? I would have thought in racing, you could just decat and forget? No, there are no emissions tests. And no, you can't just decat. It would be impractical to try to emissions test race cars. But it's a requirement that all post-2003 race ca...

Re: Ceramic CATS and CAT recommendations

I'm not sure my contribution is very useful for people with road cars, but for what it's worth. My race car uses a Jetex, 100CEL, FIA approved, high temperature, stainless steel monolith, cat, with 5" body, and 3" pipes. It's not cheap (about £250 for the bare cat), but it does a great job. Jetex re...

Re: fuel economy 101

New Duke. If an s1 was doing 4500rpm at 70mph in sixth gear, then it would be at 9000rpm at 140mph. That's a long way from correct. In fact, even my 5.1 diff doesn't lower the gearing by that much (I do 3950rpm at 70mph in sixth). The RX-8 reaches its top speed of 146mph in fifth gear, and at very c...

Re: fuel economy 101

Right. At a genuine 70mph the various version of the RX-8 will be doing the following revs: s1 192: 3150rpm s1 231: 3400rpm s1 auto: 2700rpm s2 192: 3250rpm s2 231 (and R3): 3450rpm s2 auto: 2300rpm ( :shock: ) If you put an R3 gearbox in an s1 231 your revs will be 3200rpm If you put an s1 231 diff...

Re: fuel economy 101

New Duke. Fully agree. Your question was valid, and your assumptions are reasonable. Raising the gearing might help. Nobody knows, and it would be interesting to find out. I'm not sure about your gear ratio calcs though, so I'm going to do a couple of sums... Dan. Jeez, you like to prod the controve...

Re: Verdict on use of Shell Helix HX8 ECT 5W-40 synthetic oil without a SOHN/COFS

I use HX7 10W-40, and I think a few others do as well.

If I wasn't racing, and used my car in winter, I'd probably drop to 5W-40 or 5W-30.

It's all guess work though... :?

Re: fuel economy 101

This kind of discussion always makes me smile. No-one knows the optimum gearing for an RX-8. Mazda are the only people with enough information to calculate it, and they almost certainly didn't bother. They definitely had a free choice in gear ratios, so they put in exactly what they wanted, and ther...

Re: Paul's MX-5 NC with a 231 heart

Did it have aftermarket polybushes in it then? The RX8 OEM bushes are certainly sleeved, and I can't believe Mazda would use unsleeved bushes.

It must be a pretty scary situation. Glad you're through the worst of it. Japan gets more than it's share of major events, with earthquakes and so on, but this cyclone looked particularly bad. We've been following it closely at work, and could see by Wednesday that it was heading straight for Japan,...

Re: 370z help

P0725 seems a very specific code (engine speed sensor circuit fault). It sort of implies wiring rather than sensor issues. The trigger wheel looks OK. The sensor is new from Nissan.

I assume you are asking whether that oil is OK to use in your SOHN / COFS tank (or as pre-mix)? I believe it's fine for this application.

Re: Child Seat

Children must use a rear-facing seat until the they are 15 months old. Never fit a rear-facing child seat in the front if there is an active airbag on the passenger side of the car. That implies that it's fine to use a rear-facing baby seat in the front of an RX-8 - AS LONG AS YOU DISABLE THE AIRBA...
