Shorter Runners for FAST Intake!!!

You of all people should know what you can spin aluminum rods to, Christian... If the crank is perfection then I'd say even 12k is a reality. It's all in the valvetrain... Or an OHC head that's 100% custom...
Anyway, I think it's a typo and it should say 7.0

Until I see all three runners, on the same setup, it's pointless.... and I doubt they are going to show all three because it would be pretty obvious to people the amount you lose down low, compared to the amount gained up top... if they did that, they wouldn't sell many of these new runners that they spent plenty of r&d and production costs on.
Buyer beware.

I'm not saying they don't serve a purpose, because they do for those people only interested in racing where rpms don't drop below a certain rpm ever, like drag racing where you launch at x,xxx rpm, and during the shifts, it never drops below that point, but for the vast majority of people, even road racers, we don't live above those rpms.

Still.....I got 3.70 gears on my A6 'SS'......so that's really just a minor concern.
The longer it takes Vararam to come out with their intake, the more likely I am to go with the FAST runners.

The only 'rub' I have is just how much would be lost below 3500 RPMs with the High-HP runners versus the Standard Length runners.

True....not like it matters to me at all. Cathedral stuff gets no love anymore. But the msd seems very promising for the ls7.

I doubt that's where the shift in power would be.
Looking at the graph between the high hp & race runners. I would think the standard runners would make more power, than the high hp, everywhere up to around 6000-6500rpm maybe.

but the standard runners start to die off at 6000 and are done by 6200ish. Many of us want to spin to 7000 - 7500 which only leaves us with a Super Vic as an option. I'm not really concerned with power below 3500 as I will seldom see that in a race. I very much care about performance 5500 - 7500.

Don't know if this has been linked yet but here is a vid of some testing:

Great video! It is all about the combo. As my motors power range is around 4500-6500rpm I would choose the longest runners. I don't think the bit of power up top, from the mid runners, would justify the losses through the band.
It's really awesome how you can tune the intake to the combo.
