deciding on a intake for a sbm weiand stealth or air gap

Agreed.

If this is a street car that has no heating or cooling issues, you've only got two questions to ask yourself, with a corresponding answer;

- Will this engine be used in 40°F or lower weather or do you have exhaust manifolds? - If so, use the Weiand.
- Will this engine be used in 90°F or higher weather or do you have headers? - If so, use the Edelbrock.

I disagree with the Weiand to be used with exhaust manifold and not headers.
I disagree with the RPM not to be used with exhaust manifolds. This thinking demotes both intakes in there capabilities and there flexabilities. Either intake can be used effectively in any application. (One may out shine the other. This is application & purpose dependent.)

I own a RPM A-G and a LD340. Between the two, application dependent and if used in a similar mild/medium powered engine, there is no real differance between them to argue about. The diff. Is the RPM doesn't like the cold and will take a while to warm up if at all in the cold.

The heated LD works year round without issue and losses a little HP on hot days.

The heat cross over in a intake is best used in a flexable double duty car and blocked when max power is sought from the intake. The heat cross over is not a detriment to performance in many if not most cases. Then Again, if your racing it, LOL, are you really concerned about drivability?
