Boss intake here and 32,000 miles and no issues shifting the auto at 7750-7800. If you shift any lower you are wasting the Boss intake. You also need to gear it properly to match the goals of your car.

Oh boy. I just can't do it man.. no doubt these 5.0s are tuff, I just got bad luck lol. If anyone is willing to run them that high there's no comparison. More power to you brotha! 32k on yours and no problems reassures me how much of a beating they can take. You need to post that around more often :)

150-175 passes in the car at the track and a few road racing events too ;)

i liked my boss intake when i had it, i say if you stay NA, go for it.

i didnt notice any tq loss down low and seemed to not stop pulling up top until switching gears. even with my booboo manual tranny, it was all good. maybe i got one of the good ones!!

I want to see what a dyno tune will get me before I go boss. Losing up to 15+ ft/lbs and only gaining half that in HP between 7500-7800 is silly to me. You are in the 7500-7800 rpms for less than half a second. Don't see where 7hp more up there will do any good. I am interested to see the curve gains from Tim though. That's what really counts.

thanks

thanks everyone for info

There is a reason why they put them on the road cars (boss and boss ls) and not the drag car (CJ). Danny your right your only in that RPM range for a short time in a drag race but you could be in that RPM range for a good amount of time on a road course. If anyone doesn't want theirs I'll take it off thier hands lol

how did you get a picture to pop up when you post

Actually the CJ has an intake very similar to the Boss but moves the rpm range even higher

Exactly so you can be in the power band longer due to not staying in an RPM range as a road car would.

From what I've heard is that the CJ intake didn't extend it but rather moved it so if the Boss was 5400-7800, the CJ is 5700- 8100 now.

Hmm either way I'm sure the engineers at Ford are a lot smarter than I and know what would be best lol.

That would scare the shit out of me holding 7500+ rpms for more than a second or 2. My point was tailored to drag racing. I can definitely understanding holding higher RPMS much much longer in road racing scenarios but still scares me, when I see that gauge go red I shift!

Isn't there something with the engine that will shut down the motor or starts triggering knock if its held at 7k+ for more than 10 seconds? I might be speaking out of my ass at that one. Just something I thought I heard.

There is a setting in the tune (10 second item you mentioned) from Ford that is easily bypassed in the tune. Make sure your tuner changes this no matter what you do to your car.
