Wow neato, here you go...

 

I definitely need to make a trip up there.

 

More like 300-305 tops with just a tune, CAI and exhaust

 

ehh....LTs and the TB should get him a up to 315......i assume he has UDP also though

 

And unfortunatley, none of these numbers mean squat outside the track. Put the numbers to the pavement and then see what's what. But then again, now we need the same weather, track, driver...endless.

 

Dyno number mean more than track numbers. But dyno numbers don't mean anything without the before numbers. If you have both before and after on the same, reliable dyno, then that definitely means more than numbers from the track. Way too many variables at the track.

 

Honestly neither number means much is certain situations.....track has many factors that come into play, mostly the human factor. You can have a car with low 12 potential but you can only get it to run low 13s. The same car driven by a different person runs low 12s right after you run it.....this is where track times are misleading and when someone like Brenspeed breaks into the 12s with only CAI and tune and maybe tires, they have the "good driver" mod and not everyone with CAI and tune and tires should shoot for 12s or be disappointed they didnt get as good of time.

The dyno numbers are good to compare HP gained by an upgrade....if you take a car run it on the dyno, install UDPs and CMCV then dyno it all back to back, you see how much HP those mods adds. Using this type of data allows you to project what a similar setup should get you on a different car. Comparing Car A dyno to Car B dyno takes out the human factor that is added when comparing track times but unless done back to back will lose a good deal of its certainty when you are talking about 5-10 HP differences

 

Don't see UDP's plus 4.10's take a little HP away.

 

It's just as Darkfire mentioned ! dyno numbers don't mean squat, without the stock numbers first.

Otherwise how can you really be sure, what your car gained from stock to modified..

 

Yup. If you see my mods for my '07, when I say I threw down 284HP, it doesn't sound all that great. But when you realize I put down 241 stock, it sounds pretty decent. You need a reference point, and since dynos differ, it has to be from the same one.

 

Take it to the track, and rule out ET but instead, focus on the MPH. Driver skill, tires, traction, etc. all will affect ET but MPH is hard to screw up.

Dyno's vary too much..... unless like some of you have said, you dyno before and after and have that reference point, there's just too many variables. The track is the same way with ET; however if you know the weight of the car, the MPH at the track is a good indicator of what kind of real power you have.

 

This is what a little K&N can do (STD correction).

I know the numbers are lower than the Steeda, but considering the size difference I am not all that impressed.

 

all i know is the headers claim around 30-40 with the o/r x , the steeda cai+ elbow add around 25, and figuring around 285 stock, I figured that was about right, like I said i dont really care about dynos

 

i do have udp and cmdp's installed also

 

i need to update all that stuff, i have cams and new heads ready to go on before the supercharger this winter, hoping for around 600rwhp

 

You can't stack mods. Alone each item may add that much. But when you put them together, they give a little here and there, so once you already have a list of bolt-ons and you add on headers, you may not achieve the advertised gains.

 

 

Here are the numbers my car produced before being modded (stock) and after the mods were installed. These dyno numbers are what my car produced during the process of being custom-tuned at Swanson Performance. I have the Ford Racing 90mm CAI, which is the same as your Steeda CAI, but I also have the high-flow inlet elbow and other mods listed in my signature.

As mentioned by other board members, STD smoothing produces higher numbers than SAE. My dyno numbers reflect SAE smoothing on 5. My best dyno run showed 300RWHP 308TOR, but that's because the shop had the SAE smoothing on SAE 3. When the SAE smoothing was adjusted to 5, you see that I made 294RWHP 307Tor.

In comparison to your dyno numbers you made with STD smoothing on 5, the numbers my car produced with SAE smoothing on 5 may be slightly better than yours.

Either way, I think comparing my "stock" dyno numbers to "modded" dyno numbers is an accurate way of seeing how much HP you can pick up from the mods. The other factor to consider is that the "stock" dyno numbers were done when my car only had 700 miles on it and I'm sure the engine loosened up a bit by the time my car was modded three months later. It feels like my car has loosened up even more since it was custom-tuned 8 months ago as I am now approaching 9000 miles on the OD....

Sorry about the two different formats of my dyno runs.

my two cents,

Looks like bamachips was almost right on.

 

exactly right.
