RE-Amemiya and Apex seals......
Just read a interview in one of the new import magazines with Mr Amemiya and this question was asked of him.
"do you prefer 3mm apex seals or ceramic seals?"
his reply was " the stock seals are all that we use, they are good for 500hp. its what we use in our race car also"
Well that pretty much challenges every thought on this forum about what stock seals can handle.
another interesting note was that he said that their D1 Drift car uses the Apexi power fc and its piggy backed by the HKS PFC F-con V-pro. so they can utilize the best parts of both computers.
Now thats alot of tuning, I guess thats how they get 500hp on stock apex seals

thats a poor article to base your thoughts of stock seals on because when he says stock seals in that article, he never specifies which stock seals he uses....it could possibly be the 1st gen 3mm or the 2nd gen 3 piece 2mm or just the stock 3rd gen...there are a lot of stock mazda seals to choose from...so dont convince yourself into believing that the stock 3rd gen apex seals can handle 500 horsepower...tunning as transam said is also very important and with RE amemiya he is a very experienced rotary tuner. hope this gives you a little more insight of the broadness of his statement.
Peace out

I don't know where the idea that the stock (FD 2mm, 3-piece) seals can't handle a lot of power came from. It is a rumor that has proven to be false time and time again by high-HP cars using them successfully. It isn't true. Don't believe it. And please stop spreading it!

That's the March 2005 "Import Tuner," with the krazay new hip hop look -- hotties every other page and even an ad for a male sex enhancement supplement.
For what it's worth, it sounds like Amemiya even uses stock seals in the 20B #7 JGTC car. Of course, you have to have faith that a car mag with sex ads is paying big bucks for an accurate translator of Japanese.

In japan they have super high octane at the pump. If we had that here i'm sure almost any seal would be adequate for 500hp

All FC and FD apex seals are the same part number from Mazda.
Why would someone use the older (technology) of an SA22C apex seal?
For a 2mm, 80mm wide (i.e. 13B) apex seal, there is only ONE part from Mazda.
I'm going to discount even bothering with the RX-8 engine, cause we all know that engine sucks.

[QUOTE=Evil Aviator]No, the Japanese just use a different octane rating system. It's basically the same gasoline we get in the US.
/QUOTE]
When I was there, right on the pump it said 100(r+M), how is that different from r+m here...
Even if they were confused there and put the mon number up, 100 Ron is higher than anything we have here, our RON numbers locally at best are typically 96 and at selected stations with ethanol blends 98, giving us a PON of either 92 or 94.. So either way, their gas is higher quality or at least is rated higher than mine locally..

Yes, 100 is still pretty high for RON. I think that most super unleaded in the US is about 98 RON at this time. Note that different local regulations may have an effect on the fuel's octane rating. This is especially true of "winter gas". Also, gasoline vendors may change the octane rating for a fuel when it is sold at high altitude. Even inside the US there is a strange distribution of various regions with different fuel regulations:
http://www.mobil.com/USA-English/Fil...p%20100102.pdf
For example, Exxon Supreme is rated between 91-93, and Shell V-Power between 90-93, depending on the region in the US.
Unfortunately, all of you high-boost guys are really more interested in MON, so a higher RON does not necessarily mean that the gas is "better". At least the PON takes MON into account, although it would be nice if the gasoline vendors actually published the MON more prominently in public.

In other parts of the world, their climates for the most parts are alot less extreme, in swing, with concentrated refinery capacity, their gas probably ends up being alot more consistent in grade than ours, hence the ron rating. Its interesting in the Japanese article to see the comparison, their low is just about spot on to our regular, same with the mid, but there is a spread in the premium of about 2 or more octane points depending on what grade of North America fuel the premium is rated to.
I read the article on RE in "import tuner" or what ever that rag was called, terrible layout, I think the editor needs a good does of ritalin...
I questioned some guys over there what apex seals they use, 99% of the shops used stock seals even in their dyno queen tuner cars, if they were gonna get real trick they used scoot NB seals, but those were even rarely used..Mazda is best according to those guys and they are probably right....Max
