Does Meth Injection Make Power on E85? Dyno

We are back for MQB Monday!
This week we are hooking up meth injection, otherwise known as "Boost Juice" to the Audi a3, to show you what kind of power you can gain with and without it. In this video we are going to be performing a dyno run with E85 in the tank, and then later this week we will be showing you the same data with 93 octane!
We are curious to know, do you guys think meth injection is worth it when running e85 in the tank?
Let us know down below!
As always, Stay #bdttuned

With meth you can increase timing and boost more so than with just normal pump gas. My car goes from about 380whp to about 420 with wmi and still running colder air intake temps

[@Sinister6_cuv]

You absolutely answered my question. No real power difference when running a full flex e85 tune. I ran 93 and water-meth and went from 430hp to 546. Now I'm upgrading with forged internals, bigger turbo, and flex E. I will now sell my Snow Performance.

Glad the video helped! I will say cooling ghe engine down does help engine health in track day events

[@araxavionfinnie552]

What everyone is forgetting is that those lower temps mean you can run much more aggressive timing which WILL increase power

[@PGHPYROKNIGHT]

Great content, it’s time to get back to Garetts missle and finish up what’s left power wise. 😄

[@boostdynamictuning]

Should be next month. Is38 going on the a3 first. Then s4 3.0t time!

[@haroldbutler778]

He could probably add tuning for power.. add ignition power

[@coultl6556]

What was the AFR for both runs? If you didn’t pull out any fuel with a 500cc meth nozzle then you would be running crazy rich.

[@jasonjacobs8965]

I had this question also. I’ve never seen a car increase power with meth unless the AFR was accounted for.

[@Madmalchen]

@@jasonjacobs8965 correct you have to tune it or its pointless

[@jamiedavidson3648]

This is Rad. I just bought a 22 Tiguan 4motion and I’m trying to figure out how to get some good power like I had with my 2013 CC with Unitronic stage 1+ tune with DSG stage 1. So far with your videos it looks like a DV and down pipe with an ecu tune would be my best bet. I just can’t find any stage 2 tunes for my year Tiguan.. do you guys offer a stage 2 for my tiggy?

[@boostdynamictuning]

We do actually! Let me know if you need help getting setup.

[@n-i-c-k]

Maybe I missed it, but what W/M ratio and when are you starting injection?

[@boostdynamictuning]

50/50, you're right. I didn't specify that important faq. Good catch

[@RS3_WAY]

M1 or 90/10 would be drastic cooling and a bigger difference

[@mrmeadowsiscool]

colder air but no more power?

[@Madmalchen]

you have to re tune with meth otherwise its a waste you can run more boost and timing. Without tuning it will loose power as it will run rich

[@V8sareslow1]

I'm a full race at the track kind of guy. But wondering if y'all have comparison numbers between meth plus E85, and meth plus pump gas. E85 is hard to get in my area and 4 hour round trip to make just to get it. Switched from E85, to 93 octane plus meth. But makes me wonder what the numbers would be going to E85 plus meth and benefit from the cooler iat's and maybe increase boost/timing even more. Assuming y'all didn't make these changes that is where the benefits of meth would make the difference??? If you're not making the tuning changes to benefit the use of meth, is this test valid for the guys that really push it to the limit compared to the average guy that wouldn't mess with those parameters??? Thanks for the video though either way.

[@boostdynamictuning]

When on e85 you're already max mbt. So when you install meth you can't advance timing as again... maximum best timing. So on e85 no reason to run meth unless you need to cool the engine. If you look through my videos on I have a meth video on 93 octane.

[@V8sareslow1]

@@boostdynamictuning thanks. I was looking but there were a lot to scroll through. Lol. And valid point on the timing.

[@amkrill3129]

Called it 👌 I have the previous gen of the 2.0t engine for my A5 and everything I read about running meth with e85 didn't seem worth the hassle Love to see the MQB doing great. The stage 2 with e85 figures is close to my K04 + fbo custom flex fuel tune lol Hurts to see but excited to see how the platform develops overtime

[@boostdynamictuning]

These is20 can put in the work! Very impressive from this 2.0t engine. Can't wait to show you/others what is38 is capable of.

[@amkrill3129]

@@boostdynamictuning Any chance the Garrett PowerMax GT2260s is after the is38? 👀 Would love to see what others do with it besides IE

[@boostdynamictuning]

@@amkrill3129 possibly, I might just say f it, and buy all the turbos aka xl, boss 500, and the gt22 just to show you guys what really makes the power and spool up.

[@amkrill3129]

@@boostdynamictuning Can't wait! It's awesome to see all the info and charts in the videos instead of having to swarm through forum posts 😆

@@amkrill3129 preach! I'm just like you guys, cruising through the forums finding so much conflicting information! Glad I can provide valuable information, instead of a biased review. Also thanks for the positive feedback!

Pre-turbine injection is what I’m interested in seeing
