Its actually the side seals that bear the most stress on the RX-8 - not the apex seals. Common misconception

@8020Media 3 ай бұрын

That's valid - side seals do go out first a lot of times and take out the apex's with them

@ve2430 2 ай бұрын

Most of the things he said in this video are misconceptions

@jaredrule1431 2 ай бұрын

Like any rotary, the apex seals bear the brunt of the abuse due to the nature of the ignition process and spark plug position. However, you’re right that the side seals do have to deal with a lot, unlike the earlier the rotary engines. This is due to the side seals passing over the exhaust port.

@8020Media Ай бұрын

V - Are they though?

@AlecFloyd-se8de 3 ай бұрын

The biggest limit to power is the exhaust ports, earlier rotaries with the peripheral exhaust ports could do ~300 hp n/a with a good peripheral intake port added. Unfortunately with the renesis exhaust ports being in the side housings and the water jacket running really close to the ports you aren't able to do much to them in terms of porting. The intake ports already flow an enormous amount in stock configuration, way more than the exhaust ports can expel. The rotors are also pretty weak when it comes to additional horsepower, so that is a reliability concern. Also, contrary to popular belief, apex seals are not a problem with the renesis, like they were in earlier rotaries, as they don't pass over the exhaust ports. The S2 engines even have a 3rd oil injector on the rotor housing providing additional lubrication and cooling to the apex seals. As long as the omp is properly functioning and/or you are running a quality premix at the proper ratio, you should never have apex seal issues in the rx8. The side seals and oil control rings are the main point of failure in these engines.

@James-iw2zp 3 ай бұрын

how do side seals and oil control rings go bad. Is there a preventive strat ?

@8020Media 3 ай бұрын

Premix is a good point that I didn't get into in the video, but essential for maintaining some semblance of reliability. Thanks for all the additional technical color

I'm an Rx7 guy so I have to use a standalone. Do they have tunes for Rx8 that will allow you to run half bridge on stock computer?

@Pimpin_grannys Ай бұрын

Cause the ports on the rx8 are already hella wide stock u don’t have to tune unless ur full bridge and getting overlap the stock ecu will adjust as long as there is no overlap on timing

@dr_tal 2 ай бұрын

Speaking of straight pipe. Never run ioen headers. Omg that was the worst 5 mile drive of my life. I do have a question on tuning.i plan on running a fi setup. The setup is similar to a nos setup as it will only give power when activated. How do you tune for that? So that when the fi system isnt activated it runs on a stockish tune but when you activate the system it will compensate for the added air and keep everything properly fueled. Would just running a standalone wmi with the Fi setup be best? so that i know extra fueling is being added only when they fi setup is on.

the only way youll get to 230 at the wheels and beyond is a turbo or engine swap I went the cheap route and went engine swap for a 1.8t audi engine and its the best thing I've ever done its so good to drive especially with a nice large turbo on it like mine

why take the engine out of the audi?? you destroy the heart of an 8 with a piston motor and think thats doing something? you're right. you destroyed the heart of the 8. if you want an audi motor, just keep the damned audi. this is dumb and makes literally zero sense.

@@dethangelishere394 my renesis motor was destroyed and getting renesis parts in my country is wildly expensive I completed my whole engine swap including going big turbo and stand-alone ecu for less than just importing all the renesis parts I needed, I would rather have an rx8 with an engine which has similar weight rpm and fun but with none of the downsides than scrap the shell and buy something else For reference my entire swap cost me the equivalent of about $1500 I couldn’t buy and import all the parts I needed for that (I carefully priced it up and it was gonna be around 3700) much to repair my rotary so I’m glad I swapped and actually the car is much better for it

Why does no one point out N/A with an injection kit as a bolt on mod?

@8020Media 3 ай бұрын

Meth injection you mean? Virtually no benefit on a NA car. Nitrous? Rx8 responds decently well to it actually but its only good for short power gains - not really something that will consistently increase power so I don't consider it much of a worthy mod. And can damage your engine pretty easily if you don't know what your doing.
