just been talking to a lotta guys on 3.8mustang and they said meth is a great way to make more power on a boosted car... but is it safe??? see my sc doesnt have a cooling system and the thing thats killing my power most is hot air.... so what the guys on 3.8 mustang are starting to look into is meth injection. some are pulling 25* of timing and geting 15 psi out of it. from what i understand is meth sprays only when i would be in boost and the further into boost i get the more it sprays. its set up like n20 where it just sprays into the intake before the TB to make the incomming air cooler. the snow meth kits are the ones im looking into that have a low water light. this is my dd so im going to have to get a HUGE tank and make it as safe as possible. what i was going to do was get a 3 or 4 gallon tank that will lay in the spot for my spare in the trunk. i heard that 2 gallons can last a couple weeks if u drive like you would normally drive?
