Dyno Results - Current Setup vs (Later) KLG4 & IM & Cat

**TwoPedalWarrior** · 1-19-13, 17:41

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

This is my first posting to give back to a great site. I am a heavy user on the MX6.com site, same nick.

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.

Will a custom ECU bring back my mid range and some more top end? = I sure as heck hope so!

STAND BY - Xtremethings ECU Dyno results to come in the next couple weeks!!

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.

Would love to see G4 vs. Millenia #s.

**TwoPedalWarrior** · 1-19-13, 23:46

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.

**friendsofdonr** · 1-20-13, 1:51

Btw what was your torque?

**Justin L** · 1-20-13, 2:39

I want to do it now!

I emailed them back to find out if they forgot the include the torque screenshot. Air fuel ratio is interesting, but not as much as torque.

**NickR** · 1-20-13, 11:52

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.
