Intercool vs Methyl injection

[John S]

I've been considering boosting my engine and after looking into different superchargers and turbos I feel the best option for my current setup is a twin turbo system.
I've talked with the owner of the shop that did my F.A.S.T tuning and who also is big into custom turbo and pro-charger systems since he is familiar with my drivetrain setup and he recommends the injection over the intercooler.

His argument is that the size of the intercooler needed to sufficiently cool the charge air would create more work and cost more than then the gains are worth. As well as the location would inhibit engine cooling by restricting cool air from entering the radiator and also replacing the cooler air with heated air from the intercooler.



His argument for the Methyl inkection is that even though it cools the incoming air charge an additional benefit is that it also raises the octane rating of the combustion mix.

I have not been able to find much information regarding the injection and am looking for opinions on it. I know that intercooling is the most popular but are the gains really worth the expense and extra plumbing?
