Klotz (KL-640 Nitro Power Additive

I run a supercharged v8 . Yes dual exhaust , even methanol injection , snow system , i use 93 octane sunoco etc. . It is a sleeper . I find it difficult to get consistant gas . I can monitor the motor and see when knock sensor is cutting back , indicating a knock condition . First what your not going to see , smoking tires , whiplash power increase . What i see is less timing change because of poor fuel , smoother motor , reduced hesitation etc. You donot need a lot and running more is not going to make a huge difference . Unless your anal and have a lap top hooked up , like me , you maynot feel a big change . It does smooth out idle, seems to burn really clean , much better than just pump gas with out klotz. Is it worth it , ? to me yes . I think anyone into performance will notice it . Yes , small motors , like lawn , chainsaws etc , will run better, even cooler , cleaner, just don't over dose them . Start with half of recommendations . Don't expect your prius to out run a vette if you use it

I use this in my Raptor 700R and it definitely makes a difference in power and throttle response. The only thing I didn't expect was the smell of the exhaust. There's nothing wrong, it just smells different.

I tested it with a DRAGY and it didn't do anything .I have better results with E85 and putting on a TURBO now to get more HP.

Klotz is a very good additive , I use this in my dirt bike ktm 250 , I race harescrambles , adds a little more pep ,and smells like you are using high octane race fuel.

I've been running Klottz products for years. They are pricey but as the saying goes. You get what you pay for. I just wish they had a repeat customer discount

This stuff is strong. I can pull 4th gear power wheelies on my Ninja 400 now.

This would be my second purchase of this item. It smells great just like at the track.Klotz claims a 7% increase in power at the 3oz per gallon starting mixture but I feel like it was double that on my application.

I use it in my 12 against 1 chevy big block. it doesnt work as good as 114 octane 5 gal pails i get locally but its a lot cheaper and if i can only procure pump gas ill need this as a backup plan.
