Dyno Results - Current ATX Setup vs (Later) KLG4 IM, TB, Cat, MTX Swap

Hi all Thread @ PT http://forums.probetalk.com/showthread.php?t=1701311944



I know many people have wanted to know what dyno results could be for a similar setup to mine.

I will update the details as I get them. show the before and then the after dyno (When the Mods are done, for the KLG4, Millenia IM and new Magnaflow Cat)

Current Setup:

- 1994 MX6 V6 2.5 KLDE ATX w/ 136,000 Kilometers
- OBX 2.5 Headers
- STOCK Cat
- Brullen CatBack Exhaust
- Short K&N RAM Intake

Below are the results:

- appears I am running a bit lean in the mid range, might look at a fuel pressure regulator : Should add ~4HP gain, at atleast more gain in the midrange
- Magnaflow HiFlow Cat should add ~5 HP Gain
- ATX kills HP. Approx 30 HP is Lost. Plain and simple. I'd be getting lower results with out the boltons.
- Yes, I am already planning a 5 Speed swap early next year - that should yield ~20+ HP

I am still awaiting for my KLG4 IM and Millenia TB. Cat is arriving this week. Once installed in the next ~month, I will dyno again.

Car pulls bloody strong and runs damn well. Looking forward to any additional gains. Turbo will never been in the future for this car.

Dyno Results Test #1 (No KLG4 IM/Millenia TB/ HighFlow Cat.... Just Headers and catback)

Also dug around here and found this below as a potential base line comparison prior to my header & cat back upgrade on other ATX probes

Dyno Results Test #2 (With KLG4 IM/Millenia TB/Hiflow Cat/CatBack/Stock ECU


Dyno Colours : Green = Last Dyno Red = This Dyno

Horse Power Comparison




Torque Comparison




Air/Fuel Comparison




Summary of Dyno Comparison

- Is there Gains = Yes
- Are there Losses = Yes

Why are there gains?

Like Michael @ Xtremethings thought, you get more at the highend and loose in the mid range.

Why loose in the mid range between 3800RPM to 5900RPM?

The VRIS points are different for the KLG4 vs the KLDE IM. You can see that I lost 10HP+ in the Mid range, but gained 5-10HP in the top end over 6000RPM. I also lost the same % of torque in the mid range as well. And my VRIS is working right.




Dyno Results Test #3 (MTX SWAP w/KLG4 IM/Millenia TB/ HighFlow Cat/Headers and catback)





This includes all THREE major dyno runs from each test!



This MTX Swap is using a 626 5 Speed Transmission with a Fidanza 9lb flywheel. Current milage on car is 150,000KM


Please note that the Check Valve is now installed correctly, as it wasn't for Dyno Test #2





Here are the dyno results broken down into a spreadsheet. All three dyno's are represented here. I've tried my best to determin the exact #'s based on the graphs




As you can see, the Swap has netted me 30 to 50+ extra HP and torque at all sort of goodness RPMS


Dyno Results Test #4 (VAF vs ODBII MAF SWAP)

This is the offical ODB2 MAF Swap provided by Scott. As you can see, win all over. Not posted, but official dyno @ 172.8WHP. This graph shows the best Torque gain


Dyno overlayed with last dyno #3 MTX Swap. As you can see there is full truth that the VAF goes dumb, closed fuel and air mapping, over 4200RPM. The MAF just takes over where the VAF leaves off.

Gains
- 15-20 WHP
- 18-22 Torque

Why do the screen shots say Flywheel Horse Power? Unless the engine was pulled out of the car, it's impossible to calculate the flywheel HP.

Anyways, if it really means at the wheels, that's not bad at all. You'll be getting some nice numbers when you get the CAT and 5-speed in there.

I have no idea why they say Flywheel Horse Power. I will be doing two more dyno's. One with the new IM and TB, and later with the 5 speed conversion. The 5 speed is going to be at least a year away.

I wanna run a dyno after I install my walboro and afpr.... and then after I get that head done... just waiting on money to get the valve job done...

Seeing this makes me want to do it more. I hope mine is close to this.

Btw what was your torque?

That first picture does show torque. See the flatter graph, which you read against the right hand side scale? That's torque. You are getting just under 140 ft lbs of torque at 4,750 rpm. Sounds about right.

(The steeper graph, which you read against the left hand scale, shows horsepower.)

I dig around for a bit and found some Dyno ATX numbers on ProbeTalk. These are two figures, one with a Borla Exhaust w/ no Extras and the other looks stock.

So, after my current bolt ons, I've seen a decent recovery.

@Joeyv - Huh....? The first dyno was the stock DE IM....

The actual difference, its posted up top :)

First Dyno was just CATback and Header. Second Dyno was with new KLG4 IM and TB

Looking good. The mani looks like its more consistent along both hp and torque curves.... I wonder how my fs would compare.

@Mika - I won't be doing the install myself. I am going to have 5252 Motorsports do the install. Unless in the next year I buy a house with a garage, then maybe will try.

Talked with Mike @ Xtremethings and he seems happy with what he sees

Did ask if I had changed out my injectors due to my A/F ratio being different. I haven't, so it is strictly more airflow. As for the it being lean, I am hoping that his ECU will tweak that a bit. IIRC the normal ECU is 10:5:1 and his will be 12:5:1

Now that the dyno graphs show that I had lost mid range, it is good to know that I wasn't nuts thinking I was loosing mid range. We shall see with the new ECU and the new VRIS points.

I suspect that if the new ECU returns my mid range power, the data on the dyno will possibly be the same as my DE IM with stock ECU, but the higher end RPM will be different.

So adding a KLG4 is possibly only a gain for the highend range.....
