im wondering...i only had my evo for 3 month and the only mod i done is the Blitz SUS power intake... it been driving fine for weeks..then today..i noticed... my evo doesnt accelerate at 3000rpm anymore..i hear the turbo spool up but i dunt feel the boost... im in second gear by the way... and when im in 3rd gear...i can feel and hear evo accelerating at 3000rpm... something wrong?

 

I dont feel the turbo until 3500?

 

Get the intake off the car if you have not tuned for it. It throws your MAF signal all out of wack. Most likely it's making your car very rich to compensate for the increased air flow or you could have a boost leak.

 

Check your intercooler piping.

 

i find intakes to be of no use, i installed a jwt popcharger intake on my 350z and it stalled my car, i didn't get any whp gains..maybe like one, but driveability sucked...i would just go for a drop in filter into the stock airbox where theres no heat soak going on...when i trade in my evo in december...i'm not gonna touch the intake

 

when i first installed it...it wouldnt accelerate at all..then i find the pipes flew off...of i took them and tight them up...everything is workin ok... i mean...for the acceleration... i don't FEEL any boost at all in 2nd gear...i even went up to 6000...nothin...
but when i change to 3rd...wahh lahh...i felt it good...

 

if you dont mind my askin why you tradin it in?

 

Those intakes take away from low end and give it back up high RPM. It's normal I think.

But my turbo really hits when I hit 3500 RPM.

 

really doent make sense to me. works in one gear but not the other? Like everyne else said by max 3500RPM my heads in the seat.

 

yeh all gears except for 5th. 5th at 3500 rpm is fairely soft.

 

you have a leak/disconnection in the intake somewhere between the maf and the intake mani

 

yeh, but he's saying it's only happening on 2nd gear.

The leak don't skip gears, if it leaks on 2nd, it should leak on the rest of the gears.

 

I noticed similar effect after my open intake install.

But after replacing stock bov with aftermarket Forge VTA bov its much more responsive. I thing stock bov leaks.

Also, you should install a boost gauge to measure the boost.

Do you have an Evo and a 350Z now?

 

omg its the guy from srt forums who troll'd 350zmotoring lol,

i'm trading in 350z for evo 8 in december
