I would like to see how your numbers would look like with a little more boost and cooler weather. I say 380whp is possible, but until that happends we will never know.
Also you should consider comparing your numbers with other EVOs on the same dyno. By doing that you can see that your numbers aren't really that low compared to other EVOs on that same dyno. For example this EVO VIII made 351.32whp and 325.35wtq on 91 octane and on Tuning Technologies Dyno with the following mods-
-K&N Drop-in Air Filter
-Dejon Powerhouse metal intake pipe
-Forced Performance EVO Green Turbo (20g-5-IX)
-Dejon Powerhouse Manual Boost Controller
-APS Dual Vent Blow off valve
-[forum-restricted] Cam Gears (-4i/-1e)
-HKS 272i/272e Camshafts
-ARP Headstuds
-FIC 850cc Fuel Injectors dialed in at 713cc
-Walbro 255lph fuel pump
-NGK Iridium -Step colder- Spark Plugs (BPR7EIX) (Gapped at .021)
-Forced Performance Turbo Outlet Pipe
-Greddy V-Spec Intercooler
-Greedy Lower Intercooler Pipe
-AMS 3" Turbo Back Exhaust w/Testpipe
The other pull (416whp) is with race fuel.
And like I said earlier, with a little more boost and colder temps I am sure you could see 370-380whp.

Last thing, just to put this matter to rest. The record on that Dyno (Tuning Technologies) for any EVO with a Green or Stock turbo on 91 octane is a EVO IX that made 376.04whp and 329.80wtq and I can assure you when that dyno was done it wasn't no 101 degrees. So my point is your numbers aren't so far off, if even off at all, compared to other EVOs on that dyno. If you keep comparing your numbers to 93-94octane East Coast/Midwest EVOs your just gonna be disappointed.
The only problem here is having a built motor with 20g-LT and only running 21psi with 91oct. That's an enormous waste of time and money, imo. If you're going to build the motor and upgrade the turbo, then USE IT. You should be running 28-30psi on race gas, alky/meth injection, or E-85. 21psi with 91oct is completely senseless for all the money spent on mods.
Put in some proper fuel and boost, and that bad boy will be SCREAMING.
One note about the temps. I see that SAE correction was being used, so the true numbers are probably another 10whp/10wtq lower. Yes, the heat makes it hard to make power, but SAE correction tries to make up for it by giving you artificially raised numbers.

boost was 21psi. 91octane. I bought the car used and never had it dynoed before.
Compression was tested 8 months ago. 190 across the board.
The previous owner said it made 340hp and 307tq. same dyno
mods were same as above except
2.0 factory block
9.8 hotside
stock o2 housing
software XEDE with Smart
no port work
I assume 91octane 23psi.
I was disapponited because the car did make great numbers with the 2.0 and evo 8 turbo. And if you compare the numbers to the old setup to the current numbers= no such good improvement

how does the car feel between then & now? i had a dyno test performed @ a different shop, to compare cams, the dyno said it only made 10 whp more between 6k on up, but yet the within aem logged data, it made on average +8whp from 4k on up with a max gain of 19whp & moved the car .1sec quicker from 60-80mph!!! that .1 sec = basically pulling a car length in 3rd gear alone. from 40-85mph in 3rd gear was .148 seconds quicker!!
the dyno didnt show much of a gain, but the car was so much quicker via logged data.
dont get too hung up on dyno data, what did other cars dyno @ on the same day? were they down, average or high when comparing to cars with similar mods?
A few points that I would like to share:
1. Please stop talking about the impact of 102* F when the posted chart is clearly SAE corrected. If you really want to know what the car put down with 102* F, then trun OFF the correction factor and the numbers will be LOWER than the chart posted.
2. This is on a dynojet which, IMO, one of the worst dynos ever made. First, it is a no load dyno so you cannot simulate load under actual road conditions. What this leads to is great dyno numbers, but once you log your car on the street, it will more than likely KNOCK. It is very easy for the EVO to turn these rollers on the dyno. Running on the street with actual drag at work puts more load on the car. Do yourself a favor and buy a tactrix cable, download Mistulogger for free and log your knock sum on the STREET. Do WOT runs in 3rd gear on a flat surface from 2500-7500 rpm and see if your car is knocking. More than likely it is.
3. Check your Rom. I have checked three tuning maps from this tuner and they all have similar patterns.
First, he block tunes the ignition maps. He basically uses the same ignition timing for an entire rpm row or two from ~ load 200 to 260 on an Evo 8 and 300 on an Evo 9. This makes your car hit the same timing regardless of load. So if you have higher load (more likelihood of knock), you will still hit the same timing number. This is a recipe for knock under high load conditions.
Why does he do this? Because it is easy and quick to tune that way. It saves him time and money.
Second, he does not scale the injectors. I have seen two maps of his with bigger injectors still scaled to the stock 513 injectors. This has all sorts of daily drivability issues. Your fuel trims will all be out of whack. One of the car that he has tuned that I checked had negative fuel trims. This means that the ECU will remove fuel after a period of regular daily driving. When you go out and do WOT runs, then your AFR will be leaner than what was initially set in the fuel table.
4. One thing that you need to check in your ignition and fuel map is the scaling. The Evo 8 has a maximum load of 260 in its maps. Given your extensive mods, then you are more than likely hitting loads higher than 260. Make sure that you maps are re-scaled to 300 so the ECU has timing and AFR numbers to read when you hit those load cells.
Hope that helps you

Here's my honest opinion.
I"m sure the car is fun to drive........but..
My 03 evo on the stock motor and stock turbo (9.8) made 365/365.........on pump
It doesn't make sense to me that you have an upgraded turbo and a stroker motor and you're making stock turbo pump gas numbers......

I would like to see how your numbers would look like with a little more boost and cooler weather. I say 380whp is possible, but until that happends we will never know.
Also you should consider comparing your numbers with other EVOs on the same dyno. By doing that you can see that your numbers aren't really that low compared to other EVOs on that same dyno. For example this EVO VIII made 351.32whp and 325.35wtq on 91 octane and on Tuning Technologies Dyno with the following mods-
-K&N Drop-in Air Filter
-Dejon Powerhouse metal intake pipe
-Forced Performance EVO Green Turbo (20g-5-IX)
-Dejon Powerhouse Manual Boost Controller
-APS Dual Vent Blow off valve
-[forum-restricted] Cam Gears (-4i/-1e)
-HKS 272i/272e Camshafts
-ARP Headstuds
-FIC 850cc Fuel Injectors dialed in at 713cc
-Walbro 255lph fuel pump
-NGK Iridium -Step colder- Spark Plugs (BPR7EIX) (Gapped at .021)
-Forced Performance Turbo Outlet Pipe
-Greddy V-Spec Intercooler
-Greedy Lower Intercooler Pipe
-AMS 3" Turbo Back Exhaust w/Testpipe
The other pull (416whp) is with race fuel.
And like I said earlier, with a little more boost and colder temps I am sure you could see 370-380whp.

Don't forget the stock parts in the mix Stock air box, stock intake manifold, stock throttle body, stock exhaust manifold, stock o2 housing, & stock ECU!My car has lots more in her I just have to start taking care of the small things (along with with a new clutch)....I plan to use the 18lbs spring, port the exhaust manifold, port out the hotside, use an open element filter (aem w/dry flow), 2 step colder plugs, invidia o2 housing and then retune for pump/meth and C-16...
BTW here are the correct Dyno charts...when they posted those charts they used the last pulls but those weren't the best...we started going down a bit and stopped the session since i reached max boost for the mods/fuel...
This is the race fuel chart...
This is the pump gas chart with the 16g comparison...
Here's my honest opinion.

What dyno are you basing your numbers from? Also what PSI and fuel were you using?
