Boss intake where your limiter?

Hey guys I just decided to pull the plug in a boss manifold and jlt intake. I so hyped up but I want to know where u guys have ur limiters set so when I get my new tunes after I buy the parts in March. I want the limiter to at safe level that in cause I bounce I can sleep at night. I a lot of sprited driving and some auto cross and I have to admit I've hit my 93 bama races tunes a couple of times it happens but any info thanks guys

Also interested to see what people are running up to and especially if done in a track environment for extended periods of time. Would love to take my engine to 7500 rpm or so once I get out I warranty

I'd probably set it to 7800 and try to shift around 7600, i like the cushion.

That's a little extreme, even with the boss intake, unless the motor is running the boss exhaust cams with the tune optimized for them.

I think I'd max the revs at 7500.

The springs are the issue after 7500 the stock springs can cause valve float at that point

Interesting conversation. I have read some of the engineering specs on the coyote version of the 5.0. Some people get away with 7800+ but 7500 should be the "limit".

This. I spun mine 7600-7800, it's the only way you actually see gains.

If you're not wanting to rev it that high, remove boss intake and re-install stock intake and have a faster car

kinda my thought. I wouldn't put a boss intake on my car for just three hundred extra RPM.

A coworker has a 2012 Boss with longtubes and full exhaust and was dyno tuned, [no canned mail tune] it make 459-461hp and redline is set at 8000rmp. Car ran 11.60s with some 2.0 60 foot times until he gets sorted out.


Ill post some of his videos after I get them.


EDIT: Just noticed this is a Boss manifold on a GT question.

I'm not seeing any hp gain after 7k. Why spin higher?

Wrong look at 5500rpm to 7300rpm there's a huge diffrence

Let me state that differently - looking at the improved readings with the tune, the tune flatlines about 7k. So why worry about spinning higher than 7k? Why worry about 7.6 - 7.8?? I don't see any hp gain past 7k....
