If they do much of anything, then they'll require a tune to account for it...

 

How much HP gain is added by just adding a tune w/o the intake anyone seen any results?

 

just a tune on 93 octane nets about 20hp..

 

Go look at my FRPP tune thread. You can see what just a K&N and tune does on a dyno. You notice it for sure.

Going to a true CAI, improving the flow, and adding a tune for that goes one step further. All depends on what you want.

 

Exactly, mine even says "cold air" on it, AND has snow flakes, lol.

 

Steeda CAI and tune = 407 rwhp. Both combined are awesome.

 

An aftermarket cold air box will take it one step further, as Overboost mentioned. However you have to choose a system that will flow significantly more than stock. If it does not require a tune, its not giving you much over the stock airbox.

Once you have a system that requires a retune, compared to the stock airbox your gains will be small below 4,000rpm, but a good airbox will take off from there and make more power all the way to 7,000. So there is good usable power there.

 

Question - is the intake tube really the restriction of air flow?

Or is it at the throttle body and intake manifold? Seems to me those are the restrictions regardless how large the intake tube is.

 

Yes it's worth it

 

Yeah I would like to just see a dyno with the stock air box and tune, and one of the cai and tune. I would think the cai would make a bit more top end power but not much. I think as stated that the 93 tunes would yeild around 70% of the results. But I would like some dyno numbers to back that up.

 

Didn't AM just do a test between Stock vs. Bama vs. ProCal to compare tunes? I thought the Bama tune came to 373rwhp.

Is a CAI really adding ~30+ rwhp to that?

 

Do a search, thats been done already.

 

You cant compare dyno's from different cars/days. Do a search for the tests that have been done that are the same car/day/dyno and only look at the before and after gains. Don't concentrate on whether one guy made 390 stock vs 370 stock on different cars/days/dynos. All you will do is confuse yourself.

Theres plenty of data out there.

 

Plan on a Brenspeed visit in a month to get all these Steeda suspension parts on and a dyno test. Maybe a custom tune and boss intake as well. We will see.

 

It was the same day... same dyno... same car... same fuel... same everything.

 

Our auto CAI/tune only packages are anywhere between 370-385 depending on vehicle, gear ratio, dyno, correction factor, octane, etc. Manual vehicles are seeing about 5-7% above that. In the 400 range, depending again on vehicle, gear ratio, dyno, correction factor, octane, etc. Pretty consistent results throughout most of the top tuning vendors as far as horsepower/torque per combination.

 

Yes, I meant that as a general statement of what to look for during research, not a comment against your info, I should have been more specific, sorry.

 

Ahhhh, gotcha gotcha. No biggie!

 

So Chris a Bama 93 tune will net me around 20hp and if I add a CAI it will give me another 10hp. That sound about right on a stock 5.0 auto Vert

 

If you're talking about strictly gains at the peak, yes. Throughout the curve, there are alot better gains. You can go from 375 to 405 at the peak, but it's the spot at 3500RPM (an example) that you gain as much as 40+ that make the car feel that much better.

That, throttle response, variable cam timing, shift points and firmness, etc. That's where you get that night/day difference in driveability.
