Hey guys. I was driving the Evo last night and it felt very weak and unresponsive. I was getting full boost and holding it (20psi), my check engine light isn't on, and i don't think my clutch is slipping. IT was not a dog, but I feel like I was down about 30 hp. Any ideas?

 

what mods do u have?

 

K&N open filter and MAF adaptor, AMS catback exhaust, SAFC II, hallman mbc.

 

Go drive a honda civic hybrid then get back to us.

Your just use to the current power you have.

 

My car also feels slow even though it's really probably not. It's just that you are used to driving a bad *** car everyday.

 

Possibly the gas station didnt give you premium gasoline...happened to me once.

What was the weather like?

Hot/muggy?

 

I like the bad gas Idea. You just never know, also drive a slow car for about a week then get back in the EVO.

 

i'm starting to think that this is the nature of the evo. i only have about 1500 miles on mine, and sometimes it feels a little slower than normal and i start to worry, but then other times i'm not even trying to push it and it goes like a bat out of hell. i think that airflow and ambient temperature across the intercooler can really effect how much power you're throwing down. just wait till the next cool morning, warm it up and let 'er rip. i bet it feels fine.

 

Bingo!

Ambient temperature makes a big difference.

As all of you that have cold winters can attest - force inducted cars love cold weather. Only thing to worry about in the cold is boost creep.

Conversely, hot weather is horrible for force inducted cars.

 

yeah the evo is very moody it has its good days and bad day i was reading a mag not to long ago and it said that the evo was running low 13's all day stock when she was not acting up i was like ? they said the times change from day to day and that the car is moody maybe it had to do with the weather

 

you could always do a quick compression test....pretty ez to do...nice piece of mind

 

that's always a good idea. I went WOT the other day and it didn't feel too fast, but I looked in my rear view and the cars that were with me had all but disappeared into the horizon. Sometimes, without something to judge perspective it looks/feels/seems a little slower. But it's always a good idea to check everything out just in case...

 

Nothing is wrong with your EVO you just used to the power.

 

I hope you guys are right. I'll take it out today and beat the crap out of it and see if it feels better.
