Ok, its not 500WHP from a turbo kit like alot of posts on todays pages, but...........
PERRIN EVO 9 Intake Test and Tune
We have been selling our EVO intakes for quite some time now and while we have proven they do not screw up the MAF readings we never did dyno test it. In the past we had to go to someone elses dyno to test things and in the past this item wasn't on the top of our list to prove.
Times changed, we have our own dyno, we have time to do all the little tests we wish we could have done in the past, so its time to dyno the intake!
Recently we decided to stop selling both our Air box and turbo inlet hose separately and combine it into one part. We call this new/old part the Complete Turbo intake. Since we haven't ever really dynoed this back to back on a car, we decided to do it!
Yes, black is the new color for our EVO 8-10 parts!
Before we get to the results, most intakes for the EVO are very well know to screw up the MAF sensor and cause the car to run erratic and or run very lean. Lean is not a good thing and neither is a car that doesn't run smooth. We knew why a lot of them didn't work and fixed the issue and have been selling them ever since. With that all said, the HP we were expecting was in the 10WHP area. This is what we normally see on most cars but the EVO would prove to be different.
Our Stage kits for the EVO have revolved around the AccessPORT and our parts, but we have left the intake out of the loop until now.
We first did some tweaking of the Stage 3 mapping (turboback, AccessPORT and FMIC) and before we finished, we prepped some of the clamps to be easier to remove for when it came time to swap the intake. With 7 runs done on this 92 degree day, we swapped the intake as quick as we could (took about 20min), then we did some more runs.
Run one was done while the engine was 170F, and it showed one very interest thing. More boost, oh and some HP. But we chalked it up to being a little cold. Run 2 the engine was fully warmed and same increase in boost, and even more power! In fact 30WHP! We were very surprised. We did 5 more runs to back it up and very consistently we got 30WHP!
First lets look at the boost. The boost is higher from 5500RPM on up, which is where we also see the HP start to climb. These runs were done with ZERO change to the mapping of the ECU. This means no change to the boost parameters, or targets or anything. These results show the stock intake is a restrictive part of the engine.
Shows how restrictive the stock intake really is in stage 3 form!
The dyno graphs back up the HP we consistently saw from run to run. In fact the run we used to show off the HP was one of the last runs of the set we did. This was done to show the HP gains on a slightly heat soaked car. There is no place the car lost HP. In fact it just gained power everywhere!
Not much to say here, more power!
The last graph we have is the AFR (Air Fuel Ratio) curve showing that the intake doesn't change MAF readings at all! This is one of the most important things to look at. There are intakes that screw up the MAF so bad that CEL's (Check engine lights) appear and they loose power. With these 3 graphs you can see that this is just not the case with our Intake system.
Safe AFR's means safe car, means its runs perfect, and makes great power!
So needless to say, the intake works! With a solid 20 ft-lbs and 30WHP from the intake, there is no reason why all EVO owners shouldn't consider this.
Keep in mind not intakes are created equally. Different pipes, bends, filters, and a few other things can affect how the intake meters air. Small turbulences will affect the readings and screw with how the car runs. The MAF on the EVO is a very sensitive sensor, and is known to not be happy with small changes to filters and BOV's. The above info proves our PERRIN Intake system runs the car perfectly and safely while making huge power gains!

Guys your not going to get 30whp without a tune. And besides if the car is stock already if you do a tune alone you will pick up the hp without this part. Stock air box has shown in the past good for 400+hp without a problem. For the new guys please search before you beleave in the hype.

Some truth there, this test was done on a car that was already tuned. The first graph shows JUST putting on intake with NO tweaking. The boost graph shows it all, no hype just showing our results on this one car on this one day.
"And besides if the car is stock already if you do a tune alone you will pick up the hp without this part" True, get a tune first. That is what this post was showing, gains on a tuned car with NO FURTHER tuning.
The stock air box is good, BUT if you are trying to get more boost it will be somewhat restrictive.
Also on this quote "Stock air box has shown in the past good for 400+hp without a problem" this is TRUE. But on the opposite side most every one is changing out their cats for a delete pipe when the factory cat or most high flow cats can also flow enough to make over 400hp. That was off topic, but it is a similar situation that most people treat differently than intakes, hmmm.

On a stock car you will probably not get 30HP, but you might. This gain was on a car trying to hold more boost till red line. We will always suggest a tune first.

This multi stage oiled filter is VERY good at filtering. This is the same type of filter provided on off road ATV's and Dirt Bikes to filter out dirt and sand.
Sorry, its on our site now also. But the price is $265, which is about $100 less than the parts were when separated.

Foam is one of the best filters. Look at the off road world. Every ATV and dirt bike comes with a foam filter because is the only media that can filter when dirty. The K&N and other types like that (weather dry or oiled) filter great, but as they get dirty they block air flow. With foam, the dirt gets trapped in the thickness of the foam and still allows dirt to flow around it.

Because we did our testing on our Stage 3 car with nothing but a turbo back exhaust, FMIC and ECU tune, i can say that you should see something very close to 30WHP. Our Stage 3 tune was done on 92 octane so if you have 92 or better, you should see similar results for sure.

Again, given the same parts as we had and same fuel, there is no reason you won't see something similar.

Well, yes and no. We did, we didn't fake the results, it was as back to back as possible with NO ECU tuning done between runs, and i can post up the other graphs backing up gains. You can get power from an ECU tune that is a given. But our car, tuned to Stage 3, was maxed out, wouldn't take anymore timing, or any more boost. We threw on the intake and got what you see. The increase in boost is for sure why it made more power, which shows the stock box was restrictive above 5000RPM. Also the filter that was installed had about 5000miles on it or less, and was pretty clean.
Saying that the stock air box is good to 400WHP is like saying the stock exhaust is also. Which it is, but changing them out does make power.
Remember our intake is not just the filter, its the turbo inlet pipe and filter with the air box.
I did expect some guys to doubt our results, and all we can do is provide data on our runs and hope people trust us to not tune between them creating fake data. I would even go as far as showing timing curves. We are not in the business to fake results as this does nothing but eventually blow up in our face.
I really like the way it appears to fit. I have an older bushcur intake with connical filter I was using, and despite my best efforts of position it, it constantly ends up crushed against the hood lining and even started ripping some of it off under boost. I ended up removing it as while there were definite gains after 5500, it wasnt worth the decreased driveability every day. Yours looks like a nice setup, thanks for going to the trouble of a stock to mod dyno.
