I don't think it's impossible someone will create a manifold that has better top end than the stock ported, it might never come; but it's not impossible. Is it really a true split pulse manifold anyway? (better for a twinscroll turbo vs a single ?)

gadiel ftw

 

Did you mean low end??? Certainly someone can create a manifold with better low end than a stocker 100%.. however i highly doubt itll be a huge plenum and short runner and pick up on top like these do also.. Again im no engineer..

Not sure exactly version they tested.. Here is 1 of the new ones..

 

That's sexxxy!!! How much? And will it work with a 65MM T/B?

 

Yes it comes flanged for 65mm if you like.. This is gadiel's thread.. So its only fair for him to chime in with his pricing and availability.. I just wanted to post how sweet they look!!

UPDATE Graph with Stock intake vs Magnus vs Driven Innovations



Stock intake green line
Magnus intake Red line
Driven Innovations Blue line
I think with this graph everybody are going to see the complete results, I just arrive from the dyno and decide to print the 3 graph.
No more guessing.
The result against the stock manifold demonstrate that both units are great products, on my taste I prefer the Driven Innovations because the car have more area under the curve and more usable power but both unit are great products.

 

Nice thats what I think everyone was waiting to see. How much boost was being ran?

 

+1... ????

 

Was that the Stock or Stock Ported? And which T/B was used for each run?

 

The car use the same stock TB . This TB don't have been ported.

 

how much boost?

 

Yes sorry the way I phrased it was funny. I never believed the Magnus cast had zero low end losses. But I was compelled to consider it, given I thought English Racing would have conducted a good test.

 

Boost plot, AFR, and ignition timing log please.

 

I've said about 50 times at this point, NOTHING outperforms the stock intake ported or not ported, under 5500 rpm. In that range you have to look for the intake with the least loss.

These results look very similar to the testing I did. Looking at the chart, for some reason the stock intake testing wasn't started until about 400 rpm later, had it been started sooner I'd expect to see the stock intake with more gains from 3000-5500 rather than just that small area of gains from 4400-5500.

 

I don't blame you man.. you got to defend your purchase. I would too!

But it's deffo looking like DI is king of the hill right now. Norris runs them, and many others.
