Methanol or Not to methanol?
Methanol or Not to methanol? I'm trying to ramp up my STS kit and I just bought an electronic boost controller so I can up the lbs. I'm using from 5 to 8. I was told it's safe enough for my car running only 8#'s w/ my 42 lb. injectors and my intercooler. Should I be able to safely run 8#'s or should I look into getting the methanol inj.?
from what i hear, its honestly in the tune. i dont think you will need it for 8 #'s, however you could run more boost with meth and get lower iat's, which would produce more power.
id say if you can afford it, go for it, it would just be security. if not, its not a big deal, more of an alternative for an intercooler.

Thanks, slowhawk, and cablebandit and 2000 tran. I get what you all are saying and each of you make sense. Slowhawk, Is that the first car you've put methanol on and had it not gain anything? or Is that typical? Thanks.
I think a turbo car can really use it best. If the limit of pump gas is 10psi for you because of detonation, meth will let you raise it to say 12-13 psi. This is just an example. Turbo car is just a **** twist away from more boost whereas a s/c car needs new pulley so that's why I suggested it is better on a turbo car. If you don't want to go up on boost, you can add more timing with the meth generally which is GENERALLY more power. Also, if you are getting maxed out on your inectors and or fuel pump, alky adds fuel so it takes a little load off of the injectors/pump. Now these are very general things i am saying but pretty true none the less.
Installed Meth on a Zo6 with a Magna Charger on it an we really didnt' gain a bunch of hp but a little and all the KR was gone. We did pick up 67 lbs of tq at 2000 rpms with the meth and timming etc... was just a 400 and now 467 at 2K its a torque monster. I know this isn't the optimum way to use it as it is still heated back up by the blower itself , but it still was working and it did this consecutive (5) pulls in 100+ degree air. They were all with in 5hp so it also made the car way more consistent. First car I have worked with it on and I spent all day on the dyno to get it right and also do some learning.

So far, what I've gained from this is... yes it works, no it doesn't, and it's good (sorta) That being said thanks for everyone's help on the subject. When I can muster up the cash I'm going to buy it. If nothing else maybe it will lengthen the life of my all ready high mileage (72K) baby. See ya on the street.

meth definately lets you add more boost and make more power. on my set up 11psi is the limit on pump gas and i have been up to 16psi so for with meth. at 16psi my turbo is maxed out so i can't say for sure what the limit on pump/meth is but it is higher than 16psi. i gained about 90rwhp using it and turning it up. i now have a larger turbo and will be finding out exactly how much more i can crank it up.
my alky kit suplier tells me i will be able to just keep on turning it up. says there is no limit, if i see knock then i just need to flow more meth. the real world limit would probably be how much meth can you flow without distrubition problems. i plan on pushing it hard with meth and pump gas. it is just soo nice to not have to buy race fuel.
i recently broke my 4l80e input shaft on pump gas with meth(and a new, larger turbo).
, seems to be making good power.

The reason that most people say i didnt gain **** from meth is cause they jsut add it to thier current setup. What happens is that it lowers the IAT's BUT since you are adding more fuel you jsut make it too rich. So ya have to lean it out a little which will make more power then you have to raise the boost and add more timing. Then you will get alot more power. Meth by it self with no other changes will not do ****. Slowhawk knows his **** i have NO clue why he is saying that meth didnt do **** for his car when he knows how it works and all of it benifits.

I just put meth on my truck this weekend. I was getting alot of nock retard on 8psi with all the heat we are having. After installing the meth. I can run 10 psi in this heat and get no nock retard. The motors runs alot smoother now. After I get it on the dyno and track. I should see the differences in numbers. When my 44lb injectors get here, I will strap it to the dyno and make some adjustments. We'll see what she has then.
reocamaro your numbers are way off my car made 450 at 5# and stock injectors. did they tune you for the 42 lb injectors looks like your running pig rich also what your afr on the dyno.
