75 shot before tubro or intercooler?

[BLACK6PACK]

An alky system will work much better than spraying nitrous on an intercooler. For what you're wanting to do (cool the intake charge) get an alky system. It costs $5 to refill vs. $50 for nitrous. Alky systems are well known to get the intake charge to or below ambient temps.

If you're going to get nitrous, spray it in the up pipe, otherwise get alky.

that what I am going to spary in the up pipe, I wonder how propane injection is, and if anybody uses it, Ie not in the intercooler but in the up pipe.

alky has been proven to work better than propane on the buicks. Diesels on the other hand love propane.
