People who have Jb4

I wouldn’t spend the money unless you live where you can get 93 top tier petrol at the pump. If you do, there’s a big difference.

trust me no difference. Wait for something better to come out.

The box is tightly pushed into a couple of grommets. One grommet popped off when I did mine launched itself into engine somewhere finally bounced out haha.

How did you get them to pop off?

 

[Pagliam135]

bro don't waste ur money its not worth it. I've had it and I daily it on map2 and feels like stock. best i got 0-60 is 5.20 lol

You are the first person I heard saying it does nothing

I have about 95 octane for these tests and this beasts MOVES!!!!!!

I personally wouldn’t mess with it because the manual says it’ll void your warranty

It wont. I had it installed and then took it out and the dealer never knew I had it in

I have a friend who works in the shop at Audi and yes they are not able to tell if anyone ever had it but when something serious goes out like an engine and they send it or when Audi sends someone over for thorough investigation they catch this things all the time and void warranty.

It would be difficult at best to determine if something aftermarket such as the JB4 or DS was installed unless it was catastrophic and the engine stopped running. If issues arise and the engine still runs, you remove it, and run the engine for a bit and it will overwrite anything that may “seem” odd but they would need absolute truth to deny the warranty. Otherwise they’ll have a lawsuit on their hands and in court they have to prove their case.

Just my two cents after working at Mazda corporate for 6 years

Just know I’m giving y’all a hard time, but writing / admitting to having these installed and removing them will be used against you. Nothing is secret on the big ole World Wide Web, lol. You already know this though

I have tried not many people have it. I’ve seen one bald guy promoting it and two installation videos.

I think we have seen the same videos with the same interest/questions. Berger Tuning did one recently, just watched it tonight.

They talked like 93 octane was this elusive rating. I guess in some states. Here in Texas, it’s just normal Premium. It’s all I feed RHOnin.

Yeah here in Miami, we have either 87/regular unleaded, 89/middle or 93. We don’t have 91. At least that I’ve seen.

How are you launching?

Was talking about e85. Idk if they’ll ever know about that either tbh

Did you just push the airbox up hard and they pop off?

 

[JS59]

How are you launching?

I actually surprised we aren't seeing any better 0-60 times. With map 3 and certainly map 4, this thing puts out near TRX whp - but I haven't seen a 0-60 time that even sniffs 4 seconds. I think some of the magazines were getting 3.7 0-60s on the TRX - I expected someone to get 4 seconds or better by now. My guess is there is more hp & tq under the curve with the TT vs supercharged - so same whp should be equal or better 0-60. Maybe the gearing is different? Who knows.

Perhaps the RHO doesn’t make full boost during launch control, whereas the TRX is supercharged and ready immediately off the line?
Tuners may have to play with launch control programming to get it to build more boost.

Also, on the map 4 setting (kill mode) with the right fuel, the trap speed in the 1/4 mile should be indicative of the power this is making compared to the TRX.

We realistically probably need a side by side race of a JB4 RHO vs stock TRX.

I plan on doing just this next week
