Just A Heads Up! I Was Tuning On The Dyno Today And I Ran Out Of Methenal, So I Decided To Run Denatured Alky & Water. I Lost 30 Hp! I Normally Run Methenal Straight. Big Difference. I Just Thought I Would Let You Guys Know.

 

Interesting. I ran denatured when I did a dyno run in the Typhoon (stock setup) and ended up 307hp/455tq, would have been interesting to see if it changed with methanol.

Do you normally run 100% meth or mixed with water?? I know that when I ran a mix, it didn't seem as strong, so I went to 100% and it felt better, not to mention I hit 26psi on 87 octane with no knock... (and yes, I normally run super, but it was just an experiment as to the effectiveness of alky injection vs. gas prices)

 

I had the same result when I last dynoed with the Whipple, although I only gained about 20 HP. There was definately a difference.

 

This is very interesting. Where you able to see why the power loss occured? Did you get knock? Did it alter your A/F? Did your IAT's rise? I havent tried to get the most out of running meth as Im still on the stock shortblock, but Im very interested as to why you lost so much power.

 

Well, I think it is because we tuned my truck origonally with meth 100%. (From what I understand), meth is better for fueling. Denatered is better for kr. Both cool Iat's very well. It just depends on what you need most. My maps where leaner with the denatured/water. I didn't use full 100% denatured alky though. That would be a good test as well. I used to have two typhoons and one syclone. I love those trucks. I will be getting another soon. Denatered would be great for those trucks, Kr was a huge issue with my Typhoon. I was going to use the aquamist kit on it, but I did not like the kit, I ended up saleing it.

 

What about a Denatured Alky and meth mix? I want the HP of meth but I have a huge kr problem.
I run strait meth now and my Alky kit is turned all the way up. The controler starts spraing a little after 1 psi, and I'm thinking about another nozzle. lol

 

Wow! That is alot of meth! My gain and intial are set really low. Nice video in your sig! I dont think you can mix them. If you have alot of kr, I would try 100% denatured alky. If you still have kr after that, it's must be false knock. They both help with kr, just one alittle better. That is what I have been told.

 

How lean was it on the denatured? On my Lightning there was just over a full point change in A/F when swapping from denatured to methanol, both 100%, no water. The methanol was leaner and required richening of the maf transfer to compensate. I could run more timing on denatured so I kept it that way, other than trying methanol a few times.

I my tuner didn't say. What was your kr on both meth and denatured? IAT's? It may be because I originally tuned with meth, or maybe because I only used 50% denatured alky and 50% water.

Where did you get your tune done at? I am looking for a dyno tuner, or somebody that can just tune my truck in person. I live in Stockton, Just down the road from you.
Thanks
