Porting Lower in Progress....

[Prince95GT]

got a stock lower intake the other day and started to port using the good ol dremel.... its time consuming but eh... My question is now with what I already have done, what kind of gain should I expect?

Depends on how good a job you did. I've seen ported stock intakes support 220RWHP up to 272RWHP.
