Thank you for clarifying, I know they ran out of meth and did turn it off at the switch. They really love running these kits and love the eye candy under the hood, not to mention the sound they provide.

If you happen to run out of meth with a gen 1 kit. I suggest filling it back up if possible or limping home without going into boost.

With our new kits just drive moderately.

When you say "with our new kits drive moderately" ... Are you referring to gen 2 kits? I have a gen 2 stage 2 with NO meth. I drive moderately 80% of the time, but from time to time I like to rip it up and give it a go. As you stated, YES you can run gen 2 stage 2 without meth, but you have to drive it moderately? I don't see point of having the kit and only being able to drive the car "moderately." Please clarify just a bit more? What do you consider "moderate"? I just want to fully understand what you're saying....I don't want to end up on the side of the road with issues bc I went over 4k RPM without methanol. Thanks!

I think Andrew meant if your 2nd gen level 2 kit has a meth kit installed, and is tuned for it, you should drive moderately if you run out of meth.

Ah, that would make sense. Andrew, may you confirm this statement true?

Yes correct.


Our kit wasn't designed to be driven moderately. Pedal to the metal my friends!

Thought I'd help with the difference in Gen 1 HKS (older) and Gen 2 Rotrex (Current) kits

-Older kits
-HKS Gen 1 Stg 1 Water/meth NOT needed.
-HKS Gen 1 Stg 2 Water/meth NEEDED.

-Current kits
-Rotrex Gen 2 Stg 1 Water/meth NOT needed.
-Rotrex Gen 2 Stg 2 Water/meth NOT needed.
-Rotrex Gen 2 Stg 3 Water/meth NEEDED.

-The Water/meth mix ratio is 51% de-minealized water to 49% Methanol
-If you run out of fluid or have an issue with the Water/meth system... the tune has safeguards but doesn't mean you can keep pushing the car. Drive moderate till you can fill up or fix the system issue.

-Here are some photos so you can see the differences in the blowers.
First photo is pulley side of the blowers and second photo is the bodies of the blowers
