I am so happy with my tunnel ram I can't see why I wouldn't put 1 on the race car. I also need a Max Wedge port tunnel ram. Is a sheet metal one better or less expensive than an Indy?
I do believe you’ll pay a good bit more for a sheet metal intake over a cast intake. The sheet metal intake, if properly made will make more power. A lot of the “How much more power do they make” question is way to hard to answer since it is combination dependent and cubic inch dependent.
The easier answer is, how many seriously fast racers use a cast intake compared to a sheet metal intake.
Then there is that question to you. How much power are you making and do you need the sheet metal intake.
Then there is the rarity thing. How many cast intakes are out there for your particular engine?
