Holy bellmouth batman!
Post up a picture of the welds.I think it will be a bit smaller judging by the 1262r on there now.
I believe it’s just welded on a couple runners to allow for more room to port.
Yes.Of course there is a difference, but it's extremely hard to accurately compare the differences when using boost. A 40cfm difference in heads should make a huge difference in a NA engine, but with 10-15psi boost, the change is likely to be minor. The intake is critical for a NA engine, but comparing a 5500rpm intake to a 7000rpm intake, with boost in the same rpm range, shouldn't be earth shattering.
It might, but what does that prove? Perhaps you get more useable power with the "restrictive" intake.How do you figure? If the blower makes power at 11psi, and the intake change increases to something like 13, does that not prove a restriction?
I think you dont understand my point.Nothing? We waste are money running the box r or similar with a supercharger?
I dont understand your point. Results depend on the goal and combination. Are AFR 220 heads not worth it because they didnt produce more power on a near stock 302? Is the GT 40 intake worse than a Box R because it underperformed on a 7500 RPM 427 windsor?I find this one very interesting I have had a few people tell me it's a waist of my time to even test the TFR long runner that I have. They say it sucks. Crazy thing is it has the same lower as the TFR box. This is a prime example of why I like the GT40 intake many many times with a little work they out perform the aftermarket intakes. All but the box that is.
