For real tho, if you are selling a car and say "you arent allowed to mod it", then why are you selling it? When the money hits the bank, he shouldn't care. None of the PO's business what you do with your car.
@@zandot4776 you can make whatever terms and conditions you want when selling as long as its not illegal. dude probably had an attachment to it and didnt want to see some dumb ass teen stance the fuck out of it
"the gentlemen's agreement" was not to exceed 270 HP. At least in rally manufacturers culture. The idea is that research and development had far exceeded typical power gains in a short time and to keep things interesting they limited the out right power the engines would make in favor of more technical efficiency gains for accomplishment. In other words everyone could just engineer for more power, but making one that makes that power by fine tuning the characteristics of an engine, that is an accomplishment.
There's not a lot of video information on supercharged NAs, as someone who dreams of this setup I really appreciate that someone took the time to make a good video and proper review. This really cemented in my long term plans for my NA. I'd really like details of this exhaust setup as well, it sounds great and not stupid loud
As far as I know, I'm the first to rotrex an rb25de neo. No information out there so had to engineer it all from scratch. It is faaaantastic I must say. I am definitely not sorry that I didn't just throw a turbo'd engine in like everyone else.
I feel like the only reason turbo is more popular is because it makes more power and more kick in the back, people are looking at the numbers and always want more and more. In most cases superchargers are similar to turbos, similar cost, similar reliability, but more versatility due to the lack of turbo lag
turbo kits make far more power for the money, and the availability of parts and info is a lot better as its been done a lot more than supercharging on this platform. im really happy track dog makes these rotrex kits now so you can call up the manufacturer for new parts, data, issues etc.
You moded the car, client Eastwood would be so disappointed! (Gran Torino came to mind when you said that, if you haven’t seen it you should great movie how racism really comes from a lack of understanding, and people can change. Plus Clint Eastwood who is a real life BA just look at his plane experience when he was serving, but was a BA in the movie)
From my experience, the 6 speed isn't "mushy" but it's not as smooth as the 5 speed. Its kinda notchy and fights you a little when you don't rev match just right. I'm sure a really low milage or a rebuilt unit with fresh synchros would be better. Also Ford motocraft fluid is a must.
'99 6-speed (10AE) with 110k miles, a brass bushing and weighted knob feels fantastic, nice blend of notchy yet smooth. After adding a lightweight flywheel it's even smoother, I'm inclined to believe the notchy complaints come from inexperience in feeling the synchros engage through the shifter and/or impatient shifting habits. Overall much more fun to drive with better acceleration and reliability to boot.
Dream car for me right there! I'm planning on getting a Miata in the next couple of years and will go supercharged for two reasons: linear power/lack of turbo lag and ease of install. Sick car man!
Hey Patrick! How does this car compare to the supercharged NA your brother built power wise? I know that the NB2 engines are vastly superior in terms of efficiency and usable torque, does VVT actually make a massive difference when combined with boost? It's a dream of mine to have a VVT swapped supercharged NA like you guys had, although I will probably resort to buying another Miata to swap, my current NA8 is pretty clean and I feel bad modifying it haha. I wish I could have bought your brother's old car, I hope it's being well taken care of! Cheers!
The NB engines are a great upgrade! Naturally aspirated you'll notice a huge difference between early 1.6L and 1.8L, forced induction they can feel similar. I bet if you drove them back to back you could notice a difference though, I'd imagine VVT makes a good bit more power with the same setup
@@pattyboi My long term plan is to get a good NA shell to swap an engine into and add a Rotrex C30-84, so I think I'll go with the VVT engine since the wiring is fairly straightforward. I think VVT will help a lot with low end torque, which seems to be a weakness of the rotrex setups. Your old videos on the supercharged NA are inspiring 😎
Took me a while to figure out who the guy behind the camera sounds like. Close your eyes and just try to tell me that's not Ben Lin from Gears and Gasoline.
I am doing a somewhat similar build in my car. I would love to get a few more details than were in the video. I am doing a 99bp4w in my 97 na8 with a c30-84. Should be done soon so this makes me super excited
This is awesome! I've just picked up a 1.6L NA6CE V-Special, really want to do something to the engine (as everyone does) but no idea what to do. Rotrex seems like a good idea...
Okay I'm no engineer, but "it makes 190 something ft-lbs of torque" and the rods can handle 200 something (i forgot exact numbers). Isn't that including the supercharger losses? So the rods wouldn't be good for 200 something torque to the wheels because the supercharger robs some of the torque going to the wheels?
great vid pal have watched it over and over. What's the owners insta would love to see more of the car in Ireland and looking at building a rotrex into my show eunos will be the first in Ireland.
Did they really pick the smallest supercharger they possibly could for that thing? A smaller one wouldn't have the silly lag. I couldn't believe they'd be that incompetent to not understand centrifugal compressors and put too big of a pulley on too small of a supercharger unless there literally wasn't a smaller one made.
Honestly it's hard to say, a turbo set up feels much faster because of the powerband and torque. I think they would actually be pretty close but this rotrex car is a bit more high strung. Might start to pull away at high speeds
