Kelly's 3.3L with those headers, single plug ported heads, EFI: 555whp on 91-octane pump gas

3.4L with those headers, twin-plug, same turbo, EFI and e85: 620whp and we maxed out that turbocharger.

Tom's UBER 930: 3.45L with those headers converted to twin scroll, twin-plug Xtreme-prepped heads, GT40R -- over 600whp on 91-octane pump gas, over 720whp on e85.


I'd recommend allocating those new header resources elsewhere for more bang-for-your-buck.

👍. Thanks. John

when you decide to "junk" your B&B headers, send a pm to T77911s, he may take that "junk" off your hands....
