Dont know if this has been up before, but here is a comparision test with different IC:s
For a Buick, but some may fit the TTA to. Does a V4 fit TTA ?
If you look at the test, you see that a stock looses 5 psi in pressure drop while a stocker with duttneck on looses 3 something.
That proves what many others there has seen, that a dutt neck gives you 2-3 psi more against the stocker.
The dutt neck is about 40 procent more effecient when it comes to pressure drop.
