The HP line looks likes its pretty wobbly past 4300 rpm's do most tunes from the RA community look like that?

 

Your numbers look good to me. Your torque curve falls of fairly quickly after your peak, and looks a bit bumpy on its way down. This leads me to believe that you have more of a restriction in your exhaust than you think. I'd be willing to bet that you'd net 10-15 whp just by deleting your cat.

Most people understand the following principles, but I offer them as a basic reminder.

Don't forget how horsepower is calculated, it's just torque x rpm / 5252. Your torque curve is directly related to your boost level, and your boost level is governed by the rpm of the turbo. All turbos have a max flow capacity, but based on your numbers, you're not there yet.

Like all Ralliarts, you're hitting high boost early on (at your torque peak) after which it tapers off. This happens because you need to flow more and more air as rpms increase, therefore your boost drops even tho your turbo is working harder. The trick is to make it taper less. To hold boost longer, you need to spin the turbo faster, so you need more exhaust flow. To get more exhaust flow, you need less restrictions in your exhaust.

Here's the numbers.

At about 3000 rpms, you're making max torque (273). Multiply these two together and divide by 5252, you're at 156 whp. You can take a ruler to the dyno chart and get more accurate than that, but it gives you a good idea.

At about 5900 rpms, you're making max hp (224). Your torque here has fallen off to about 200 ft-lbs. If you follow the hp line before the peak, there was another peak at 4800 rpms, just after the mivec changeover point. Between these points, the torque falls quickly.

If you remove some restriction from your exhaust, you'll notice that your torque curve becomes more smooth and won't fall so quickly after 4800 rpms. If you smooth out that torque curve, you might be able to hold 210 or even 215 tq to 6200 rpms before it falls off.

215 wtq at 6200 rpms = 254whp

Have a look at some of the dyno sheets posted by other members on here. The torque curve peaks at the same place but the bottom doesn't fall out of it so quickly. This is where the power you expected is hiding.

 

Here's a link to my graphs, they are very smooth:

you are missing a peak of power around 55-5700 like slee and most of us have. IF you look at the graph it looks like you leaned out too much there, or have a boost leak, because you should have had higher numbers in that area.

 

I'm running at 5500, no leak.

Also I have no cat, just 3 resonators.. but where the 3in ends is just before the muffler where it drops to 2.50 piping and then in to duel 2. 50 output magnaflow.

 

you clearly didnt get what i was saying.

 

I meant "I'am running lean at 5500, no leak." <-- i was told by the tuner that I was running lean in the higher RPms

Also I have no cat, just 3 resonators.. but where the 3in ends is just before the muffler where it drops to 2.50 piping and then in to duel 2. 50 output magnaflow.

I has typing off a phone, so it corrected it..

The weird thing is When I floor it my AFR goes all the way to 10AFR and stays that way, but doesn't the lower numbers like 10-12 mean "super RICH" and not lean?

 

do u have black relay? or the Blue one for fuel pump?

 

The lower the AFR # is, the richer your car is running.

 

u should ask this to your tuner, its his responsibility to explain to u...
do u have the AEM gauge?

Was ur tuner reading ur AFR from the same gauge/sensor?

 

Seems inline for what mods you have.

In reality, you only have three power adders at your level, the boost controller, test pipe and tune.

 

That's what I'm saying so if I running lean at higher rpms when I floor it then why would it go all the way to 10 (the rich side) and stay there?

 

What should I be looking at if I get the EVO X turbo?

Possible 260 somthing horsepower, and a lil more Torque?

 

Wont get too much more torque, but will get more HP.

 

Go get an AMS eflash or call them. Still opening up the exhaust with a proper system is gonna net you better gains.
