LESS than 100 REASONS to NEVER DYNO a CHEAP MAZDA RX8

[@doctor2bob]

I wanted a yellow RX8 when I saw one at the 2003 Tokyo motor show. I settled for a Red 2005 MazdaSpeed 6 speed. Still have it. On second engine at 100k miles

[@ClwnJuNkY]

I miss my mazda speed rx8 6speed !!!

[@nickw0tup]

My theory behind the low compression at the start of the video is the rebuild is still just bedding in , it's choked up by the blocked cats , hence the misfire arriving 2nd to last pull so the run in has been ass , now that you cleaned up the plugs and gave it some beans it's building compression, clear the cats , clean the plugs run another comp test then power run it again

[@nickw0tup]

This comment aged well . Compression come up , as mentioned in his recent video rx8 hot starts

[@BushidoDriver]

.... except this "rebuild" already had 20,000 miles on it before he even took ownership....

[@Oborowatabinostk]

Hiqh torque starter is the single best upgrade for rotaries imo. Next, maybe coils

[@jerryglennie5375]

Odd question but since i just had my stock starter rebuilt a year ago what is a good replacement upgrade for the S1 renesis?

[@phillipliems7963]

Can't wait to see how exhaust and intake mods play out on the dyno! Thanks for all you do!

[@347windsor3]

Rad P & SRC are my two fav shows ATM, love the content !

[@surrrithux]

not many people show the dyno process, always nice to see that something extra. Be nice to see a dyno vid for the RADx7 next... so I hoped there is more you recorded.

[@1969gearhead]

Ernie is phenomenal with rotaries. He has a lot of seat time on my DynoJet 😂

[@overbuiltautomotive1299]

I love this video A++ no bs just great Hey the tweaked leaf blowers with tuned exhaust as silly superchargerZ would be fun to see lol but lol i love my rx7 1982 with that said i do get why folks get rid of the Wankel.but not me ill keep my 12a

[@wherestheleakmaam7291]

13:03 that's my rx8 in the background, lol

[@Oborowatabinostk]

STL gang?

[@wherestheleakmaam7291]

Yessir

[@rylandsilva]

Plugs, coils...Good to know! Catless, premix and intake should help achieve a few more horses too?

[@mx3fto]

Intake not so much, the stock intake is actually pretty good and hard to beat unless you want more noise. Decat can free up some horses but I have found it lowers the low down torque even further. Probably great for track but not so great on the street

[@vinniesmith7455]

I’ll tell you this … mine is at 144k …I’ve put bennet built coils and mid pipe to an rx7fc single muffler … only thing I’m fighting right now is the valves in the intake not opening when they should … try also freeing them or cleaning them … it may make a bit more …. And solenoids also for the emissions will be shit and are a detriment to any vehicle …. But yeah they can free up air flow and make things open up better … in my street port block I’ve cleaned up the intake immensely and plan on shaving some meat off of the valves themselves to open up faster …. But I feel the issue with rx8s are restriction to cure low end torque and it being NA it’s gonna have limits unless you swop a four port and itb it and simplify it … but you still lose low end till supposedly 5k but it’ll rev and gain without limitations … but it’s a new thing to put time into and research and trial an error ! Also stand alone ecu !!!!!! Huge game changer and running proper afr sensors and so on may be a better go to …to tune better for rpm ratios to afr’s !

[@RobotHotSauce]

Dyno the Green Machine? It’d be interesting to see what your track rat is putting down

[@RADPotential]

I'll bring it out before I take it apart for sure.

[@rotaryperfection]

You need to put that thing on the freeway bro. Wish you had an inspection camera to stick in the leading plug holes. I wanna see how carboned up that engine is.

[@MRJBTA]

Those stock compression numbers are better than my brand new stage 2 engine from Pettit Racing (located in Riviera Beach, FL).

[@ibrahimchukadze9684]

It would be awesome to see detailed rebuild rx8 engine possible with street or bridge porting .

[@pv4083]

Great video very informative

[@clintonlangerak7972]

Ssv/vdi confirmed working?

[@RADPotential]

Yes we checked both. And the aux ports. All working

[@swampyfox8688]

Remember when you really wanted Santa to bring you a shiny new bike… and he brought a 20yr old spray painted junker?? That’s kinda how I feel today. LOL But I get it. The motor isn’t worth testing all the swaps that were planned. 😢

[@RADPotential]

I'm still going to do the swaps. Just going to make some more improvements between now and then to better show the results

[@e.v.a.l.s]

lol i was starting to type 96 hp but then you said the number before i could finish this message

[@njs461]

Bone stock with used parts is not bone stock it’s old and tired. This is why good rotary shops only want to build engines with at least two new housings and seals

[@skaterboi8922]

the wood is halarious

[@mastercricket7626]

This is my , because I can't afford a FD future build 😅😢😅...peace and love bro keep it rad stay safe and build on l8z fam and have fun brotha

[@charlieshankles]

Blinded by science!!!

[@lugnut93]

My 2009 has 95 psi on both rotors at 114k miles. I’ll take it!

[@BushidoDriver]

Did you drive that to the dyno?! 😬 Hope you didn't encounter any steep on ramps....🤣

[@lochsloy217]

150 hp stock?

[@fisshuman]

Goddamn, my Mitshubishi 1.5l i4 engine from pickup truck makes more than the "Superior" Rx8 with less fuel to drive and cheaper maintenance.😂

[@Indio_Performance]

Why the hate?

[@ADudesRotary]

Baaa haa haa 😂😂😂 time for the crusher! Damn I own an RX8😢😢😢

[@patrickd.7880]

This was proven by racing beat when the rx8 first came out. They had no where near the 225hp they advertised.

[@RedLine_Renesis]

At some point your rear stat will start screaming.

[@dogi117]

😂😂😂😂😂😂😂😂 dyno on a blown engine 😂😂😂😂😂

[@harrod19]

I am deeply, deeply offended!

[@ryansmiley5495]

I have the same car.

[@ryansmiley5495]

Still in fuel learning mode.

[@Johnny_OSG]

That's a new low world record for a RX8. And I thought Vargas's 158 was rock bottom

[@zav8687]

Vid or link?

[@Johnny_OSG]

@@zav8687 kzbin.info/www/bejne/sH2Qp3Z7q7CLqK8si=BKgVmugQLuJFqhDN towards the end

[@Nitrocity7151]

141hp is my guess

[@Nitrocity7151]

WOW

[@samgarcia2207]

On the Rx8 4th gear is 1:1

[@RADPotential]

Everywhere I read says 5th is 1-1

[@whyshouldipickaname]

probably depends wether you have 5 or 6 gears version

[@TexasVexes]

156

[@tigerrider6711]

Pathetic.
