Talking JB1/JB4 EA888 Gen3.B??? - 05-04-2018, 02:36 PM

Hi!

I have a 2017 Audi A3 with the new EA888 Gen3 B-Cycle engine. Iím waiting on parts to come out like for example, Intake system (this engine has a MAF on air box). I was wondering if there will be a JB4 for these engines. From what I read, this will completely replace the 1.8t and also the 2.0t on some vehicles, and become a mainstream engine. Any news on jb4 development?

Hi,

Yes, we have already been working on the unit for a while now. I reckon late in June to some time in July pending production speed.

Thanks,

George

Hi

Will my existing JB4 work with Ea888 gen3b later on with a firm-/software upgrade?

The Gen3B uses a different circuit board.

Any update on how the the fitment on the Polo GTI is going? Some ball park numbers in terms of gains over stock....🤩

Are you able to defeat the budack cycle without getting inside the ECU?
Guessing thatís key to getting more power🤔

Does the Polo GTI use the IS20 Turbo? & Does the higher compression ratio effect how much power you can get from the engine??

We managed to buy our own Polo so are doing thorough testing on it. The JB4 works well on it although the car has serious heat soak issues due to the tiny front mount cooler that is going to require some unique tuning that only a piggy back like the JB4 can do.
On the exhaust housing we can see its IHI IS20 although the compressor side looks a bid different. We will only know when the wheels eventually get measure but it looks to have large power gain capability.
Below is a wheel power dyno with the car cooled down on 91ron using map3 with 5psi average over stock.

Looks very nice! What should I expect from the jb4 on my 2017 Audi A3 EA888.b? It has the big intercooler and it looks like a IS20 too.

With more cooling power gains should be similar if not more.
