Might as well pack that intake an send it to Crystal Lake, Il for the most hp per $ around(shameless plug).

Wow that's like almost 80hp with the honing
! Did you have any other mods to achieve that number? Also, how long did it take for the porting work to get done and is the pricing similar to what a port done by hand costs?
Back in the old days, extrude honing was the way to go. Intakes and heads were extruded and the results were always spectacular - at least on Mustangs. Just not sure why I haven't really seen it mentioned here with regards to the ZR-1...Seems logical to me
