Double 65mm Throttle Body

[Granddaddy Marq]

My questions are, Is the horse power gain worth the money? Would it be enough of a power gain on a N/A motor? Would there need to be an injector or tune upgrade? There is a used one for sale near me for $225. If the gain's not enough to justify on an N/A motor, should I buy it, put it on the shelf and hope some day a supercharger falls out of the sky on top of my motor.

That was one of the first mods I did. Glassman's BBK twin 65mm TB. It only improved throttle response. Not HP. I had to port match the upper plenum too or the blades won't open all the way. Not worth it NA imho.

I agree. Good for throttle response and that's it......
