FM turbo testing, intake manifold shootout! - MX-5 Miata Forum

VICS vs flatop with GT2560:

Wow so impressive to see so little difference between VICS and Flat top (price lowering sound)

 

I still have a hard time accepting FM's dyno results, especially when they show a GT2560 performs better than an EFR.

 

I thought the whole point of the flat top was for big power... 178hp, I wouldn't think there would be a big difference anyways.

 

They make more power even on NA applications.

 

Don't think I'm being a dick because of other threads, but I get that they make more power on NA. My point is that it's not really a huge amount (probably not worth what they are selling for, and the difficulty getting them). But for higher power applications the power increase would be more dramatic, making it worthwhile. So a comparison at low power levels doesn't seem that helpful, and a bit misleading on the point of a square top.

I admit I could be way off here.

 

From what I gather for "big power" people go to the Honda manifolds.

 

So get VICS and spend the money on Supermiata/Skunk 2 TB, you'll get some dough for cat food......
