Now how do you and miguel get around this problem? You guys are in the 25-40psi range Thanks for you time matt..
p.s is it the meth that helps make boost temps low?
Matt, I assume your running 93oct. If this is the case, you are octane limited which is why you aren't able to take advantage of higher boost on your current turbo. Methanol injection is one of many "race gas" options to raise octane level, knock resistance, and my personal favorite it's superior cooling affect as 100% methanol stays below ambient temperature. If you are looking for more power on pump gas, upgrade your turbo to something larger and more efficient, but if you want to push your turbo to it's maximum output choose one of the many higher octane "race gas" options such as E85, methanol/ethanol injection, 110oct, c16, etc...
