BDT: B8.5 S4 Meth Injection Install

[@DamianSpeck]

Does TB wmi nozzle placement allow enough space/time for atomization and even distribution into the cylinders?

[@boostdynamictuning]

@DamianSpeck yes, but I would have liked more time for cooling affect. As for atomization, of course. That happens based on pressure, not time. As for evenly going to each cylinder, lol the world will never know, but probably as this car has individual cylinder fuel control and trims look fine per cylinder.

Hello friend, I would like to know if I have my s4 with apr stage 2 plus what would be the combination of set-up in control to make the most of it

[@72defender]

That acceleration at the end...🤯

[@moza6127]

Did you get any vibration noise inside the cabin from the pump ? I have the same setup and the sound from the pump is annoying

[@boostdynamictuning]

We did not

[@Mena6e.c7]

What’s the best setuop

[@ryanpass8020]

I have the APR stage 2+ Ultra and I'm curious what the gain would be for this (1000cc) meth injection setup would be. Thanks for the videos!!!

[@funnyvids4uman]

Thx for the s4 videos man! Does this car have a upgraded HX? Also wanted to ask u about the brembo q5 calipers...i installed and bleed them twice with a power bleeder but i have a mushy pedal...what do u suggest that i do? Thx!

[@boostdynamictuning]

funnyvids4uman heat exchanger is required for any dual pulley setup. As for brakes you need to buy ecs brake bleeder tool. Makes it so much easier and use harbor freight suction tools to catch the fluid.

Hey guys, did you actually have to drill the methanol tank to the car or not ?, I was actually thinking about putting it in the trunk but this seems like a better idea because I can have all the space in my trunk, also another question did you guys put the cover back on that section or what happens if it’s raining and water gets there, thanks !

[@aliriodiaz3182]

hello friend, what difference is there in installing the nozzle after the tb with installing it before the tb. and what would be the setting in the proper control

[@boostdynamictuning]

This really depends on your goal with meth injection. You can raise the ethonal level with meth. Doing so, I would bring the nozzle closer to the throttle body. If you're using meth for mainly cooling, then it needs more time when sprayed to actually cool the air. As for settings, this really is your tuners choice. Personally, as I am the calibrator, I'll set it at 10psi, then 15psi.

[@mastalee1776]

Where or did the port job on the sc?

[@Moe1985]

Hi, did you use a TB spacer to mount the nozzle?

[@boostdynamictuning]

No.

[@PedroSilva-uy4yz]

good afternoon. where can i buy an 80 mm butterfly body

[@yueyu1896]

nice vid！can i ask where do you get the boost signal for the aem controller？is there a kit to buy ordiy？

[@boostdynamictuning]

Yes, I bought the ecs boost tap for the 3.0t s4. Nice and easy to install

[@alexsauceda4128]

Is a retune required?

[@boostdynamictuning]

depends on cc, 500cc and more yes

[@berkekaanokutan9817]

I have 91 oct available only how much would meth benefit me in terms of whp on stage 2 setup

[@boostdynamictuning]

It's all personal preference, but meth provides an easy 20 whp gain.

[@brancocapitanich9562]

Cuantos hp de ganancia le dio el meth? Gracias

[@admiraldirtbag4336]

IAT before and after please. There were threads on Audizine showing negligible benefits (1-2 degrees Celsius). Really interested to see what benefits you have

[@boostdynamictuning]

MaxGentleman I’ll try, car is no longer with me.

[@admiraldirtbag4336]

@@boostdynamictuning thanks, I thought because you said at the start of the video "cool intake temps and make real horsepower" there'd be results including before and after. I really thought your S4 blower swap video was top notch with excellent detail. This video was a bit disappointing as the quality and content wasn't as high a standard. Appreciate the (free) quality content, so thanks!

[@boostdynamictuning]

MaxGentleman this is what happens when you have someone rushing you, compared to a calm collected video. We do things professionally but the customer who bought the car from me didn’t give us anytime to make a legit install video. Not much you can do but throw a video together to show people the jeist of it. Next videos to come will actually show gains and possible Dyno numbers. If it comes anytime soon.

[@admiraldirtbag4336]

@@boostdynamictuning Hey that's great to hear about the results. I can appreciate your customer rushed you, the video was still good.

[@boostdynamictuning]

MaxGentleman I mean, honestly I don’t like the video. Almost didn’t drop it because of the horrible quality. This is not how you take a how to video :( but again working with what I can and I’m just trying to help you guys.

[@Driftwood1478]

Is the meth injection setup only being used to cool IATs, or are you also taking advantage of the extra octane its providing? Are you compensating the AFR in the tune, or just letting it eat? Sorry for the questions, methanol injection is just super interesting for me, lol.

[@boostdynamictuning]

It’s being used for both. The nozzle installed in the video is spraying 1000cc’s. This means I definitely had to tune for it. I don’t get how people run it and hope their fuel trims keeps up. Not how I like to do things. I took out about 20-30% fuel in some areas in the tune for the meth. You can now know how much fuel it’s actually spraying.

[@Driftwood1478]

@@boostdynamictuning Thanks for clarifying. Ya, 1000cc nozzle is huge. I used to run the devils own kit with the dO3 nozzle (370ml/min) and still required a considerable amount of tuning. But it sure did wake up the car, lol. 👍

[@BigMotorLover]

@@boostdynamictuning which tuning platform are you using that allows you to add/remove fuel? Most tunes for these cars are OTS and they refuse to make revisions

[@boostdynamictuning]

@@BigMotorLover I actually do my own custom tuning using winols.

Butt connectors ???

Can you give us some numbers please. Dyno or dragy please

[@boostdynamictuning]

Coming shortly

Hmmm🤔im interested lol

Dyno dyno

[@boostdynamictuning]

I don’t have a Dyno near me. I just purchased one and will have Dyno of newer cars come January.

[@rickeywilbourn4867]

Boost Dynamic Tuning that cool. Keep up the good work and don’t stop

Rickey Wilbourn I’m trying 😎 thank you for the support, we couldn’t do it without you!
