Hi guys. With all the buzz on the Boss intake going around, I wanted to take the opportunity to share our own finding and opinions on this intake.
The candidate car for our dyno's was not completely stock. It already had an intake and tune package making well over 400 at the wheels. The vehicle in question had stock exhaust and no other power modifications outside the Steeda cold air and tune.
We switched to the Boss intake and made many pulls to optimize the tune and get the best results we could. The results are below.
As you can see, peak to peak numbers went up 20 horsepower. As expected though where the stock manifold falls off, the Boss manifold is no where near finished. The highlighted point around 7250rpm shows an impressive 53hp gain. Peak torque is down 14ft/lbs, but points in the midrange loose as much as 27 ft/lbs of torque.
Is this worth it to upgrade if you already have a cold air and tune? For many I think the answer will be yes, but this is definitely not for everyone.
An owner with a cold air/tune, and 3.31 gears that goes to the Boss manifold, tune, and 3.73's at the same time I think will be more than happy as the gears would absorb the feel of the torque loss. It is all going to matter on perspective and intended use.
I may have missed it, but I dont think I've seen anyone do a dyno on a stock intake/stock airbox/stock tune car vs the Boss intake/cold air/tune. We didnt have a car available to us to do the test this way.
We have speculated that compared to a completely bone stock car, the boss intake/cold air/tune combo would give up little if any torque compared to a car that is already making more torque because of tuning.
Looking though all the stock dyno's we had, all of them shut off pretty early due to the stock rev limiter so there is no way to compare how much top end power you make compared to a completely stock car.
I did find a dyno pull from one of our very early dyno development days. The pull is from a car with a stock airbox and very minor tune tweaks as we were just starting the development work. This pull was making around 10 to 12hp more than stock. Because it has a tune, the rev limiter is not an issue and you can use it just to get a vague idea of what the possibilities are.
Disclaimer: This comparison is in no way scientific. It is not same day/same car. Only same dyno on completely different days and weather conditions. It does give us a vague idea on what the gains may possibly be compared to a mostly stock car. Not accurate, but useful enough to give us trend.
As you can see, the torque curve is pretty close. This is not same car/same day as I mentioned earlier so I wont go as far to say that the Boss intake setup actually made more torque than stock, but the trend certainly points to near stock levels of torque. So for owners satisfied with the stock torque curve and want massive horsepower gains, this comparison tends to trend towards that exact result. Based on this comparison you are looking at the possibility of 80 horsepower at high RPM with near stock torque levels. Very interesting to say the least.
