Can you supercharge a mazda rx8

The ProCharger gives you a 'more powerful naturally aspirated' feel which assures the driver with confidence. Of course the power is right there with a blip of the throttle all the way to the RPM redline. Our ultimate aim was to extract power without losing any of the high revving character of the Renesis rotary.

After all that is the reason you love rotary power , right? Unlike the turbo, D-1SC does it easily with only a fraction of the boost. The Renesis motor in the RX-8 runs a high static compression, therefore, keeping boost low was one of our primary objectives for a reliable daily driven RX ProCharger D-1SC is self-contained. Meaning, the oil needed to lubricate the gears is self-contained within the ProCharger unit itself.

Other supercharger systems require punching a hole in the oil pan and running oil lines into the supercharger unit.

Re: Rx8 supercharging vs supercharging Z or gt86 Post by SeriousSam » Wed Aug 29, pm It's not about it 'now' being possible, it's just nobody bothers because you've got to invest ten to fifteen grand in a car that's worth a fraction of that. Puts people off somewhat. If my engine chooses to let go at some future point, I'll be going with an FD swap, but there's plenty of other stuff I need to sort before then.

This would bring you up to a solid and reliable BHP, in a package that's not too far removed from what Mazda were aiming at with the RX-8 in terms of handling and balance. If power is your aim, then the RX-8 isn't an easy car to hit the numbers with, so your ideas of a Z or GT are sound enough. Neither of those engines was built for boost from the factory, so may require further engine mods to support bigger power, but if a modest lift is enough then that's probably the easiest and cheapest way.

I'm still tempted by the idea of a SX for the same reason - easy modification to release more horsepower. Re: Rx8 supercharging vs supercharging Z or gt86 Post by Dr. FrankenRex » Wed Aug 29, pm Fair play, apologies for repeating what I'd heard on the internet!

Re: Rx8 supercharging vs supercharging Z or gt86 Post by Kellytm » Wed Aug 29, pm From what I could see on the gt86, the cossie kit was the best one. Think it was good for Bhopal before the con rods need replacing or there abouts. I think after looking at the racing beat site, there were a fair few other mods required before supercharging or turbocharging the Renesis.

If I can get something similar to the old 90s jap sport car performance out of the 8, by supercharging, engine swap Re: Rx8 supercharging vs supercharging Z or gt86 Post by njkmr » Wed Aug 29, pm I have been looking on YouTube of late at some of the engine swaps done on an RX8 and LS1 conversions seem fairly popular in the states. I think its a Corvette engine and obviously they are putting out mega bhp with reliability.

Does get the mind thinking! From a reputable dealer. The higher the boost level you desire to run, the greater the likelihood you will need to address the issue of a lowered compression ratio. In our experience, we have found that 5 psi. As the above comments would suggest, we do not recommend supercharging an otherwise stock, "non-turbo-based" unmodified engine.

When you weigh the anticipated power gains against the very real likelihood of a premature, and costly, engine failure it's likely not worth the headaches. If you are willing to build an engine that is capable of handling the increased heat loads that superchargers develop, the following tips will prove beneficial, increasing the likelihood of a long-life engine.

Increase oil pressure to approximately psi, or to psi or more if the engine is bridge-ported or peripherally ported we use to psi in the HP 3-rotor engine. Use the oil pump assembly found in the engine, or a dry sump oil system. This requires using a front housing because of the extra passage at the bottom of the pump. Perform the water jacket modification discussed previously in the Rotor Housing Tips section to improve heat transfer. If it is possible on your year vehicle to do so, adjust the output on the metering oil pump unit to double the flow at 2, RPM.

If the flow cannot be adequately increased in this fashion you will need to pre-mix oil with the fuel. Intake Systems. Carburetor Applications. Fuel Pressure. Carburetor Tuning. Misc Tips.
