This was a 2007 STi we just finished tuning after installing the fuel upgrades and the new Perrin performance rotated turbo kit. We are running pretty mild timing up top and only 24psi on the currently 93oct tune. He is thrilled with the results as the butt-dyno was more impressive than the heat soaked dyno plots. Either way figured some people would like to take a look! He has a EL big runner manifold and race gas tuning on his agenda in the near future. He is also discussing some cams to help keep pulling up top.

40hp increase is easily a different dyno away. Plus, look at the ambient temp!

Heat is a killer guys. This superflow seems pretty low reading, and the dyno cell needs improvements in airflow. Not only is it hot, but we arent able to bring much fresh air in. Needs more fans. We will have some race gas numbers out of the car eventually from the sounds of it, which is when it gets really interesting imo.

Thanks,
Alex Goodwin

Thanks Juan, hope you have been doing well! That is definitely down like 100whp based off what we made on our evox.

Thanks,

^^^^^ Definetly. A hot day with high humidity and a dyno that really doesnt have sufficent fans is a killer if your looking for realistic dyno numbers. 100 Degree day with 40% humidity yelided my Dom 3XTR on meth 370/350. lol. I want winter

I can vouch for heat. Retuned my 1.5xtr with EL headers and made -30whp from my last tune...in January! This is on a COBB mustang dyno. Intake temps were 130.

So, nice tune! Any idea what the intake temps were?

I'm waiting for a fully temp-controlled dyno chamber......

Thanks for your feedback. A lot of people don't realize what heat and humidity can do when trying to make power. I don't actually tune the cars myself, our owner Todd handles that, so I am not %100 certain on intake air temps. I can tell you the dyno cell was WAYYY too hot with minimal air flow.

We are actually going to be moving to a new 8000sq ft facility and at the same time installing our new AWD in-house dyno. We are focusing on optimal airflow for the room, but wont be able to add climate control at this point and time.

Thanks,
Alex Goodwin

Was it even on the same type of dyno? If not its completely worthless of a comparison.

Second look at conditions of both runs, probably very different. As mentioned heat is a killer. I wouldn't except big power on our dyno these days as even shop temps are 78 degrees by noon with the doors closed and cooler running 24/7. Put a car on the dyno and temps go up in no time.

I gotta say, I would love it if the whole shop was climate controlled. We have a clean room that is climate controlled for our motors, otherwise we are sweatin it out.

Hi all,

This my subaru, on that note...

I was at the dyno during the tune, and not only was it hot, it was sticky.
3sx doesnt have anywhere near sufficiant fan power to feed my system...suprising considering all of their builds are turbo applications???

Anyway, the car drives great and has more power than anybody needs. When that gtx hits stride the car pulls like a nasty beast lol. Almost beyond my expectaions. I can vouch for motionlabs, both with their work quality AND power output/tunes. Todd knows his ****, and Alex always makes sure everything is in the customers best interest.

Im thinking of bringing fans with me to te next tune!!!! And i could only wish i was joking :/

Pics of the car to follow.

What was the temperature when you put down those numbers? And every dyno reads differently. Was it a dynojet? Lol

I've been tuning for 7-8 years, professionally at least (even longer if you count the years as I was crafting my trade). Anyway, every year it never fails, the HEAT just saps the power during the summer months!

We've had a an interesting time this year with our dyno investment. We bought a newly designed AWD dyno (this will be the 3rd one to ship of 5 made to date) back in the middle of February and there has been delay after delay. It is FINALLY coming to fruition tomorrow, Wednesday July 18th, and being scheduled for pick up by Friday to Charlotte. We are told "only and act of God would prevent this from taking place" lol).

Well, I feel this is worth mentioning since having an off-site dyno usage agreement really takes away the element of control. For example, we are also moving into a new building August 1st. It has a room that we are installing a large exhaust fan to move air out of the room. We already purchased $3k worth of fans to move air into the room, and another mammoth fan to push air across the front of the car. The fan placed at the front of the car is considered a 'high velocity fan' and moves about 17i000cfm of air but in a very narrow concentration. This will provide excellent cooling for the car. The other large fans at the front of the room simply move fresh air in and expel at the back of the room with the carbon emissions.

This type of control will better enable us to perform better and safer testing and provide more consistent results. It will also allow for longer test periods while running steady-state tuning tests. This becomes a lot more important with the higher powered and unique component set ups.

My impressions of Ethan's STi is that it hits hard, and should prove some pretty quick track times. We are tuning it on some mild race gas soon so it should be interesting. This motor was built by another shop several years ago, but runs strong IMO. It does need more mods and I know that he is going to be picking up an UP and header soon. Those two components are holding it back in its current state.

What do you mean by that? I think the tune would be safe to run at an HPDE even or something like that if thats what you mean.

The car will actually be back this afternoon and we will finally have the race gas numbers on MS109. Last time on the dyno we had the OEM clutch slip so since then we have installed a exedy stage2 heavy duty clutch kit and lightweight flywheel. I also didnt realize I didnt post up the pump gas re-tune we did. We ended up making 385whp on pump gas before calling it quits. No need to push it on pump gas when you are bout to fill it up with some liquid gold like MS109.

Race gas numbers coming up soon!

Thanks,
Alex Goodwin

Hey Alex,

I realize this is an older thread, and your newer thread mentions the change to your new dyno. (Congratulations on that btw)

Indeed temperature can make a significant difference in realized power, especially in a car where there are multiple feedback control systems that are critical to the end power factor (boost being an important one).

On your most recent tune post, I noted that you list the corrections as: "Default Corrections". I am curious if this reflect the SAE J1349 standard corrections from 77 Degrees F and 29.23 in/Hg and 0% Humidity? Some dyno software systems allow selection of a couple of different correction methods, with the SAE version being the most common.

I wrote an extensive thread about the use of dyno corrections a few years ago:

http://forums.nasioc.com/forums/show...no+corrections

I noticed there were a couple of posts from other tuners that were using significant correction factors, in part because they were at altitude. Unfortunately this leave such an incredible misrepresentation of the results. The uncorrected results are the results. The correction does not provide a pass on the laws of physics. The cars make what the cars make.

In your particular case the correction may not be that big, although a quick mental calculation says that 103 degrees and 60% humidity is about 7-8%.

I do understand the 'business need' to have numbers that match what other people get, and of course being in a hot climate puts you at a significant (and as you demonstrated under appreciated) disadvantage.

I am curious as to your thoughts.

Cheers,

Jeff Sponaugle

Put some ms109 in and crank the boost to 29 and make another 260/220 more.

We actually re-tuned the car on both 93OCT and MS109. The engine is a bit noisy from the drop in pistons that were put in at another shop so we ended up rescaling the knock sensor when we put it back on the dyno. Once we did that we were able to safely pick up more power. We still didnt spend much time on the 93 tune though because he had 55gal of ms109 sitting at his warehouse

Thanks,
Alex Goodwin
