Not sure if this is the right place, mods move if you feel necessary.

Been tuning more and more Evo's lately, and I worked on one of our employees cars last friday.

Since I don't claim to be an Evo master, I've been taking this crazy slow. But I figured I'd ask what ya'll thought.

This is an '03 Evo 8 with a catless downpipe, catback, Ebay FMIC, intake, cams, running around 20 PSI on 93 oct.

Note, we don't use dyno corrected numbers at our shop, and the temperatures are 99+ degrees during this tune.

Personally, I think it's great! Especially for an uncorrected number. But, I'd rather here it from you guys if I'm on base, or way off.

Untuned, but with the cams, etc. I want to say the car was around 270's when it was baselined back in February (uncorrected again).



Thanks for looking!

not bad!!
I need cams!

 

93 oct, you need to up the boost and you will see more gains.

 

We did, and it unstabilized. It didn't through any knock counts in Mitsulogger, but the curve clearly started to wander around as it was on the verge of misfire/detonation, plus the car felt like *** on the dyno.

Consider this.... correct that 310WHP, like every other shop in the world, and it be somewhere in the 325-335 range.

For me at least (tuning being subjective), I'd rather deliver a car that leaves 10 less HP on the table, but drives like butter, then one that is ragged, but fast.

I think it is alittle low. My car without alky and with the stock 03 turbo put down 343whp at 21psi with a boost leak.

 

Interesting, well to give you a form of comparison (at least as this dyno reads), we've had people here who rent our dyno for dyno days from Al from Dynoflash, to Adam over at Devo tuning (formally from AMS), and they average around 280-310 on similarly tuned cars over the last 12 months.

While that's the only bench mark I can use, it's incredible the type of numbers you've gotten! If that's the case, I want to know where they've failed!

I can crank boost, and flood the car with fuel, and it sure does go up in power fast, but maybe I'm just used to how Subaru's drive, and I'm trying to tune Evo's to that standard. Wrongfully, maybe, but nonetheless.

Thanks for the input!

what were your conditions (temp, humidity ect.) SAE or uncorrected? what mods did the car have? Cuz if it had everything else in you list in the sig. thats more then my car has (the one Jorge tuned on friday) i have a boost leak too, at the throttle body. Regardless 343whp is a pretty sweet number . the car did have more power in it, with a 1 or 2 count up in higher RPM. The way it is now, is the way i wanted it with 0 knock counts from start to finish. I like to drive the car hard, and i dont like knowing the car has a 1 or 2 count during a 3rd gear pull on a dyno. Because in 4th or 5th at the track it might be knocking more and then it pulls timing . If i can talk Jorge into it, we'll do 100 octane on my stock turbo and see what the car can do .

 

that's some low vertical resolution there...
I say give er more boost, put the cams to work. Unless you have bad 93 there...

 

it wasnt happy with any more then 20~22psi. It was starting to throw 1 counts at higher boost levels, maybe i had a bad tank of gas, but the temp of the dyno room defiantly wasnt helping. But I definatly need a bigger turbo to get full use of the cams i have. maybe a 20g or 30r
