So my tuner and I used evoscan's virtual dyno for this, and it said I was only making 290whp and 276lbs of torque. The car has full 3" exhaust, 10.5 hotside, Wally fuel pump, Apexi intake, upper and lower I/c piping, hks 272's, Megan o2 dump, test pipe, mbc set at 24psi, and a cool looking spark plug cover.

But seriously, that seems kinda low doesn't it? Or would that be accurate? I was thinking mid 300's???



Figured I'd slap the graphs up here for people to see. Thanks again to Matt.

 

should make more yes. but if you don't have a good FMIC don't get a new tune until you install one.. it will help greatly with lower octane fuels.

 

you are on stock injectors i assume... don't worry i only made 291whp and 296wtq with my 9 turbo, 3" tbe, ebay CXracing IC, 255 walbro, injen intake/icp, boost solenoid set at 24psi stock injectors stock cams on 91 cali pump.... kinda dissapointed but ran a 12.7 107mph at sacramento for my best time

 

OP, did you and your tuner do a boost leak test?

Was this on 93 or E85?

 

I'll be boost leak testing today, and yes that's on 93 octane. When I bought the car it was making 286awhp with a dyno graph to prove it. Since this I added cams, test pipe, and the o2 dump. Maybe there's just a God awful boost leak. Will post after the test.

 

Yeah, there could be a boost leak somewhere in your IC pipes and/or the throttle-body seals could be leaking which is a common occurrence on the Evo.

As for adding the HKS cams, as far as cams are concerned, those are mild cams. You're not going to see a big power gain with those.

 

use the standalone VD software not the one in evoscan i think the standalone one is more accurate

 

I tend to disagree with people that arent fans of the HKS 272 They are a very solid cam and compliment a stock turbo broad powerband evo very nicely, They are usually worth 30-40WHP on stock turbo EVO8, and thats a pretty good chunk of power.

VR4 Definatly sounds like something is fishy, i noticed you didnt mention a upgraded DV or BOV in your mod list, they can really cause some power robbing issues if they are opening as they turn your turbo into a flamethrower making it work twice as hard, and heatsoaking the intercooler, causing you to run less timing to negate the heat. I had a metal one that was opening a LOT at about 24PSI on my car and caused some pretty rediculous power loss.

Also tuned an EVO9 last night that was getting surging/boost fluctuation in long rpm pulls that we ended up tracing back to the Stock DV opening and closing during pulls, Im starting to wonder if the springs in them get weaker and weaker as they are getting older.

 

+1

Yeah, your numbers are low. Should be least 300s. I made 310 in VD with just Evo 9 turbo, 3" TBE, filter, wally, mbc and tune.

sorry man i have to disagree, ive been on these forums since 2006 and i have never seen a pair of hks 272's add 30-40whp on a stock turbo 8.... and you wont find one if you search, what you will find though is gsc s2's and kelfords making 30-40whp on stock turbos and its usually closer to 30whp.

if you disagree then why are there so many threads about how much people gained when they switched from hks 272's to gsc s2's.


anyways to the thread starter, i suggest you talk to tscompusa he is a great tuner and always has consistant good results. I dont know who is tuning your car now but if they dont specialize in evos or only tune evo's id probably stay away. and +1 on the intercooler and i suggest going to 26psi, thats a pretty good level of boost and its not going to get you into any trouble with a competent tuner.

 

 

yea something isnt right then. i would do a boost leak test, maybe change the spark plugs, if you have the tools compression test the cyl. then if everything checks out new tuner you should be at-least 330whp

 

It does have an evo IX bov. Forgot to put that in the list of mods. The hks are mild, no doubt, but the AMS cam test had a 38whp difference (different turbo of course.) even if I only gained half of that, I still come short to what it should be. Not to mention the other mods that were put on.

Either way, just made the boost leak tester so I'll have the results in a couple hours.

 

Is evoscan;s VD in dynoject or MD mode? I thought the numbers looked fine, but I was comparing to what my car did on a MD with similar mods...

 

There is nothing wrong with a IX BOV. I used mine up until 27 psi. They are just fine.
