Emira JB4 Tuning Now Available for I4 & V6 Cars!

[sixtyy]

40whp for map 1 plus 91. Huge gain.

Why did the green hit the rev limiter earlier than other runs?

all i know is it smell great and feels amazing, also how are you getting your hands on toluene?

Common paint stripper you can find at hardware stores. Couldn't speak to its quality for such purposes though >_>

Nice gains! I also live in the Bay Area and would like to schedule a dyno session now that I have installed the JB4. Could you share where you had this done?

It's interesting that your charts are almost the opposite of mine. All the gains on mine tend to be below 4k rpm, while all yours really start to show above 4k. Do you have the 3rd cat delete?

Was this a V6 or an i4? I didn't see any big gains on my V6. Map 1 is pretty subtle like you say, although there is a nice lift in torque at the lower rpms.

We don't really know for sure because the dynos are taken on different days months apart with different ambient conditions. This is not meant to be a knock, I'm very thankful that he went ahead and got dynos. I'm just saying you can't compare them to each other

Didn’t he record before and after plots? Or were they on different days?

His before and after are from different days with different conditions

Got it. Thanks.

Does anybody know if there are any more ways to get some extra juice out of the car? Will the JB4 continue to improve? Will they make updates on it ? Thanks

Headers, supercharger pulley, 3.7 L sleeves and pistons, and or more RPMs.

Also, someone called jokerz apparently does porting for the supercharger.

Last but not least the GT4 car uses this engine with a bigger supercharger from Harrop the tvs 1900.

People smarter than me on here might be able to comment on using E 85.

I know for twin turbo 911’s its epic

@VF Tuner is working on a few things that many of us have high hopes for.
