Sooo... 13psi w/ Meth?

 

Gains would be negligible at best. Meth = safer AFR's. The last car we built & tuned w/ ProEFI (built motor PowerLab GT35R) had meth injection. I can dig up both graphs and hp/tq #'s at the same psi w/ and w/out meth are almost identical, while the AFR's are better.

Yeah, please share. I gotta get a grip on this Meth thing. Also Darren, were you running 100% as well..just so we compare apples to apples?

 

That 13 psi was without meth.

 

Every car we tuned with meth made way better gains than negligible that for sure..We were able to run cleaner AFR's and a few degrees more timing for more power...

 

I know. Randy was wanting comparabel graphs at the same psi but with and without meth. You stated you do not want to rune a motor above 15psi on pump gas (Which I agree with) without additives.

Sooo.... We already have numbers @ 13psi w/o Meth, so how about 13psi with meth?

 

So are you saying on the graph you posted, that the only difference between the two curves is just the addition of methanol? No more boost, no more timing??

 

Someone stated earlier.....

Zoni went from 13psi and NO Meth (575rwhp) to 17psi w/Meth (648 rwhp).

So an increase of 4psi and meth = 73whp

 

so 4 psi bump?, not bad.

 

Makes sense! It looked like he was saying the gain was from meth alone.

 

Once again, meth does not make power by itself, it is not a "power adder"..Meth simply allows to run mre boost, more timing and a more agressive A/F mixture, a little bit safer on pump gas...

It also cools the AIT and boost charge a bit more..

Basically I added about 2 degrees timing and a conservative AF ratio of about 11.8, and raised the boost to 17 psi, something i would never do on pump gas, cause the amount of timing i would have to pull in addition to "SAFELY" run 17 psi on pump would negate the gains alot..

 

I think what people are saying is that your first post reads as if you made 100whp by just adding meth, that's all. Great tuning Julain -- everyone here knows you're top shelf.

LOL, I like that term..Top Shelf..Kind of like Johnny Walker Blue label...

I probably should have clarified my statements..

I should have said "we were able to make alost 100hp additional tunning on meth".
Previous numbers on the car were 555@15psi the year before...

here is the old dyno..

 

I understand all of that, your original post was just misleading....that's all. The addition of Meth definately makes a huge difference for how cheap it is compared to race gas!

 

I actually preffer meth to a mild 100-104 octane gas. The meth also has cooling properties as opposed to the slower and more predictable burn rate of race gas. Its a cheap detonation control and cooling additive.!

 

What about meth and C-16 at the same time? Just for a good race gas tune, not a daily tune.

 

Thats like mixing crack cocaine and meth! sounds like a good idea =) jk. sorry for OT

 

 

I plan to run 100% meth and 93 octane.
Julian you still didn't answer my question...was Zoni running with 100% meth or a mix?

 

50% meth, 50% Water.
