Dyno sheet of a stock block 6.1 Jeep SRT engine vehicle with addition of Mondello heads! This is a all wheel drive dyno result. The results on a 2 wheel LX type vehicle would be slightly higher.
No......By stock I mean the engine block and cam. The vehicle had a cai, catback and Diablo tune installed in both tests.
still outstanding to see that much of a power gain! Especially without headers. It is almost unheard of (key word almost because I have seen similar gains on other platforms) You so rarely find this kind of bang for the buck.
I will ask for this data. I do know that they flow approximately 350cfm. Most of the work is in the exhaust port.
god they come alive at 4 grand...mix this with a vortech and ill never get traction...Steve we need to talk more
About 3800 I can really feel the heads come alive, then matching it up with some NO2...look out at same rpm!
