High RPM type of deal? Or decent gains throughout power band? Building a ls3 now for a 88-98 truck and this would be sweet. Won't turn anything higher than probably 7k with this build. Jake do you have a link to that build? Only one I've seen is Holdener's with a 416
That's the one with Holdener. But the fact that it doesn't really lose a lot down low to the LS3 like everything else is a miracle. And then runs away from it up top.
Man for the price I'd like to try this over a regular Fast.. My build isn't anything crazy but that top end gain is convincing. Plus it looks like you can change the runners. My build is a 229/240, lift right at .600's on a 112+4 with stock ls3's. Truck is probably around 4k based off other stock 88-98 single cabs
Still amazed how well the factory LS3 intake performs. All of those aftermarket intakes have trouble keeping up until around 6k rpm.
A radius rod LS3 is pretty amazing.
I can't help but wonder if the 90mm snout was cut off an LS3 intake and a ~ 100/102 mm snout attached how much the LS3 would compare to the aftermarket intakes.
