They're a nice looking intake, but they just don't move enough air to be serious performers....even ported, they just physically don't have the material available to remove. My stock Track Heat makes even the most heavily ported Cobra or GT40 intake look silly by comparison.i really like the gt40 also,i regretfully had to let it go also with my set up...
If I ever change the intake it would have to be appealing to my eye, so there are only 4 ones of now that I physically like, cobra, gt40 tubular, saleen and the tfs r last. Yes I can always upgrade the intrake to a top end pleaser at some point and time. But a dyno n/a with the cobra is going to happen. But to see the numbers in that form will be different, I get it. But if I ever need more I can slap on a S/C and still be extremely happy cause the Dart 363 can hold that S/C in whatever appearance form I want to give it. But lastly, the intake is probably the most easily accessible variable, so I can always change it pretty fast
Trust me i would have put a Systemax II on my stroker if i didnt have the powdercoating already on my Cobra intake which matches my valvecovers but in the end im glad i kept my cobra. On a stingy mustang dyno my unported cobra made 364 rwhp 385 rwt corrected without correction actual numbers were 382rwhp 402rwt. And in all the intake shootouts on aggressive 347 stroker motor the GT40 which flows identical to the Cobra did make 20 less hp on top than the Holley and TFS R the TFS R made 20 less torque so really its what your after a little more hp but spinning your motor over 6000rpms to get it or more Torque hmm.
