Hymee Supercharger Owners Thread
As I understand it, more of you are finally receiving the balance of the Hymee S/C kit and have installs underway. Some have PMed me and I am happy to communicate in that fashion but I thought a thread to exchange ideas and compare notes might be helpful.
I know that Danny already has some modifications in mind and I'm sure other experienced modifiers will have their own ideas.
Feel free to drop in here and share them...
To kick it off in a minor way, I am shortly to install a second oil cooler (we don't get them standard like the US cars) and some gauges for oil temp/pressure and boost. What add ons are the rest of you planning for cooling and monitoring purposes?

Still waiting on the final shipment here....but ready to get started.
As for monitoring, right now I'm only looking at boost and AFR. I won't be 'tracking' this car and living in a cold climate, I'm not too worried about oil temp at this time. I'll do some measurements on oil temp and intercooler discharge temp with a separate thermocouple right after the install, but no plans for a permanent gauge on either right now....
Have you been having oil temp problems down under with only 1 cooler?

Our climate is temperate, so I'm not worried about street driving...
Pardon my ignorance but 'AFR'?

AFR - Air/Fuel Ratio, also expressed as a numerical value as lambda, with ideal lambda being 1.0. A measurement of the actual stoichiometric value of the fuel/air mixture for a given fuel vs. the ideal ratio of fuel and air for complete fuel burn. Smaller AFRs and lambdas indicate a richer than chemically optimal mixture; larger values indicate leaner mixtures. Target AFRs for pump gas are in the 12:1 ratio range.
AFRs are best measured using a wideband O2 sensor in the exhaust and are used in dyno tuning to refine fueling maps.

I'm predicting at the start these owners will see 275whp with more later on after they get their tunes dialed in, with a lot of clinking of cans of Fosters
I may have to test my manhood and get a pack of Fosters to toast their success...

In place of a second oil cooler, install an oil cooler plumbed into the heater core heater hoses.

I just want to see some Aussie FI.
Preferably accompanied by pics of scantily clad Aussie women.
Oh, ****, there goes the civilised part, sorry
Well, now that I"ve shot the genteel part to hell, let's start a pool on who hits a 'roo at speed first

The stoichiometric (chemically optimal) ratio you allude to above sets a "target" of 14.7:1 for gasoline (1.0λ). Optimal AFR depends on a multitude of factors, but I am unaware of any condition on any sort of RX-8 where 12:1 is optimal.
On an NA vehicle, optimum power generally occurs around 13:1 (.88λ). On a boosted vehicle, optimum power is around 11.5:1 (.91λ).
The actual "mean" target is bracketed by rich and lean values that are also considered "optimal".
Oh, sure. When a product comes in from one of your neighbors, you suddenly want us to go all civilized?

I'm not telling
If you and dan get your crap installed quickly, you can join us in Portland for a supercharger throwdown with dondo - if I can get more people to sign up that is....
