hey whats up guys i need help cant find the problem i got an evo 8 so when im driving a hit the gas and get to 4000 rpms the car drops power and then gains the power outa nowhere what could it be?

 

Is it when you shift or just when you are boosting to 4000 and then it dies and hits hard? Do you have a boost gauge? What is the reading as you are climbing to 4000?

 

im driving regular then i hit it and when it reaches 4000 rpms it feels like it loses boost then but one thing it does it jumps the from 4000 rpms to 4500 rpms quickly i dont have a boost gauge i just got the car 4 months ago but yea it loses boost at 3500 to 4000 then from 4000 to 4500 it does it quickly

 

Does your car have a boost controller on it, or has it been reflashed and maybe boost was changed? You may be hitting boost cut, or a coupler is loose and maybe when u hit peek boost its opens up and you loose some psi. Maybe sparkplugs.

 

What evo do you have?? Your info says "xii" which is the number 12??

 

^i think someone doesn't know his roman numerals...

 

XII is 12.

 

clutch

 

Me or the OP?

 

Mine did that... it was the clutch.

 

So what you are saying is the clutch is slipping in the transmission to cause this intermediate power loss? Seems like if the clutch was slipping, the rpms would go all the way to redline if not paying attention. i.e. motor pushing too hard and the pressure plate cant hold the clutch to the flywheel.

Just my 2 cents,

Sounds alot like clutch slippage.

 

drive up a hill and put it in fourth or fifth, hit the gas and see what happens.... experimentation..

 

LOL

 

Spark plugs!!!
