EVO IX At Switzer Performance

Eric, so stage one is going on now. Then stage 2, and then stage 3. Exciting things man, talk to you later...hey see if you can switch those IX seats out for my VIII seats...jk
It looks like the IX doesn't pull boost like the VIII does. Is this the case?
Edit: Okay after looking at the graph, maybe it pulls a little boost somewhere around 6500 - 7000 RPM. Not like my beloved 2003 that calls the cops to shut the party down at about 5500 RPM.

I knew that somewhere down the line someone who be the first critic on the numbers. Fact is that this was a car driven directly off the car lot and onto the dyno. It does not matter what the number is I guess as long as you know the baseline and have the starting point. From there on out as long as you use the same type of dyno (not a 2-wheel, mustang, etc...) the power increase for mods performed will still show the horsepower increase. If it dynoes at 275 HP baseline and I add an exhaust and it dynoed at 315HP, it still shows the gain in power. Some places are in the game to make big number, but what customers really want to see is how each part effects the car individually. Big numbers are great but the track is what proves the power.

Ok...let me help out everyone.... FIRST I sold this car to them and know it had 16 miles on it when it left to get dyno'd today. I drove over there and watched a baseline! 275 awhp on the awd dynojet. The HAVE had a 05 that did 260 (some cars are stronger then others). Most stock 05s would do 240-250 awhp there . This 06 is either a strong runner right off the bat or it is way underrated which isn't uncommon. I drove it and it felt way stronger then ALL the other stock evos i have driven....even flashed evo8s . I bet that car stock would trap 105-106mph in the 1/4 . They are modding it now and will have some stuff on it most likely before the nopi event this weekend at norwalk. This is real stuff guys ....these 06s with the updated turbo and mivec aren't going to be a joke especially with switzer's hands on it!

It seems to me that the IX has a flatter torque curve than previous Evos (especially the ole '03s). Kinda hard to compare, though with a mph graph. Could you please repost a chart that graphs rpms instead of mph? ...or better yet, upload the runfile.

notice on the sides of SPI's graph does not say SAE torque or power? This would inflate # on a cold day for sure. Check out HKS' comparison of EVO8 MR vs. EVO9 MR and their graph is SAE corrected, peak power is not much different but the 9 definitely has a nice increase from 5-6k rpm:

I know we have been through this before, but just incase anyone has missed it, These are Tyms words from that WR thread that was closed:
"Since it was mentioned in this thread, I feel it necessary to let everyone know that all of our test results and posted dyno charts are ALWAYS posted in SAE format. This accepted standard of correction from the Society of Automotive Engineers was established to maintain consistency in test results from location to location with relatively repeatable results from one atmospheric condition to another. Although this standard of correction also corrects for altitude as well, our dyno is located very near sea level which keeps our results relatively uncorrected for altitude. Testing centers located at higher elevations would obviously have SAE corrections applied that would be more aggressive."
Hope this clears this evil8, what I believe is different car, different day, different dyno

i'm not quite sure what you mean. but i pulled it in all 5 gears up to 140 mph and it seemed to pulled very strong and consistently up to redline in all the gears.
