why do you want to defeat a safe guard from over reving your motor??

oh,i guess it's that little thing of being controlled.do you think that going over will float the valves? i think it has more to give than ford says ,could be wrong.then again 155 mph is fast enough:D :D :D when we are only going 55-65 anyway right?.....i would just like to know that everything is there at my beck and call when i need it.......doug.

With a screw type blower like the eaton there is no reason to rev past 6200. Actually the guys at the track are getting their best times shifting at 6000 which is really 6200 when you actually shift. You are never going to float valves in a 32 valve engine. What you are really fighting is spark blowout and detonation. Both of these can lead to a piston problem. HTH

I have only done accelerated runs up to 6K 3-4 times and you need room and almost no traffic to do it. From 4-6K this snake starts to go really fast, really quick. There are gonna be very few situations in normal driving where you will want to go up to 6K.

I call 4-6K the "go zone" cause that's when accelaration is just awesome. I am running the Bassani X-pipe(w/cats), Bassani catback and the C&L 95mm MAF unit w/K&N. It runs like a scolded dog..................
