clean install inside with the dash and stuff. nice. never heard of anyone messing with peformance for one of those rides.

 

Yes - put it before the TB - I centered my nozzle on the divider in the TB (see pic I posted on page one of this thread)

I chose to relocate my AIT sensor a little upstream, instead of leaving it in the path of the alky nozzle. If I left the sensor in the stock location, it would be getting blasted with the alky, and I don't think I'd be getting a true reading of the AIT. Besides, I'm not sure how well that sensor would hold up, or if it would even be accurate it you start hitting it with alky.

 

Right now im tossing the idea of a meth kit vs an FMIC or a small air to water cooler. The kit im looking at is from www.snowperformance.net .. There kit comes with a nice pump and tank, I was planning on putting the tank where the battery is and running the lines straight to the vortech elbow before the IAT. Battery in the trunk ofcoarse. The main reason I want the meth kit over and intercooler is because of the octane it provides and the protection against detonation to a certain point. I have 42 LB injectors and those arent really enough either, the meth kit would make those work. I want an intercooler because they are so simple and it cools at idle and cruising, meth is only injected at WOT or under boost.. I really dont know which one to choose.. I was talking to a few shops and some said its corrosive to your oil and stuff.. others have siad it burns clean.. Dont really know what to do at this point. no $$ for and intercooler.. right now im running 145 degree intake temps cruising around and it gets up to about 165-175 beating on it.. need somekinda cooling! its late and im bored.. sorry for the long response.

 

somehow i don't see it hurting the oil at all. WWII they used a alk injection system on fighter planes. plus all the guys running it on Grand nationals with no problems. just my thoughts.

 

from what people say 24* total time is where FI like, on a dyno how much more timing could you add..

What amopunt of boost would be nice to run with alky, i was thinking of 15lbs..

 

To clarify, it be better to not compare the injection the buick crowd uses, with that used by the WW2 fighter planes. Those planes used water injection, not 'alky' injection, as is the popular 'buzz' word, to describe the water/alcohol injection made popular by the Buick crowd. The alcohol used in the planes, was a minimal amount, used solely to prevent the water from freezing. Any performance gain achieved (from alcohol), was secondary.

EDIT 01-18: In regards to last two sentences, now that I've been exposed to conflicting info, not too sure what to believe.

 

NOthing is fixed in stone and it will depend on the final engine setup... some like more, some like less...

 

i run mid 600's rw on pump only maybe 14psi and have been 20psi and 836rw on 93 oct. + 100% methanol with a snow kit. also my best mph of 144.6 was on pump gas + methanol

 

Can you benefit from and alky kit if you are running low boost numbers. I am thinking of getting another camaro since mine was totaled and might do the sts kit but im gonna have stock internals how much boost can i run im not sure if im gonna get an lt1 or an ls1.

 

Mighty Mouse, could you go over set by set how you add in the alky and add boost and timing....

 

nothing fancy about my set up.

i have one 625ml nozzle and one 375ml nozzle
both come on at the same time when the pump is given voltage through a relay triggered by my boost controller at whatever psi i set it to.. like 5 right now.

i dont have a speed adjustment, the pump is just run at full tilt.

i leave my timing at the same place it would be on race gas, and just run the boost up to the same place i could on race gas.

you will get a huge drop in a/f when the alky is added but thats fine since stoich of alky is really low like 7:1. do NOT let your computer pull fuel when the alky is added. if it does, drive the a/f to 10.0 or so instead of 11.5 for example... i had to do this with my dfi.

with a stock computer the 02's dont influence wide open so you should not have to touch anything. i would just get the a/f where you want it on race gas with the stock computer then switch

 

David,

I was thinking about leaving my tune as is at 10 psi, but adding a meoh kit to allow me to raise the boost to 15 or so psi, have hte kit activate at 8-10 psi to add the required extra fuel. Is that something I can do with the kit? or would I ahve to switch tunes again? I have a wideband to monitor AFRs but what should I aim for? just that it maintains 11s AFR?


Thanks,

 

you will want to see like 10.0-10.5 max on your wideband

depending on what kit you get it can come with an 'on' controller

if your 10psi tune is on pump gas then i thin you certainly could leave it the same and add meth and 5psi.. just watch that the a/f doesnt go anywhere near 11.5


i wish there was an exact number for both our sakes, but its a lot of calculatin' and it changes for every application

 

haha, yea, I understand.

I was looking at going with one of hte snow kits.

my tune right now is for pump gas
thanks for the tip on the AFR.
