Hey All. I have had my evo for about two years now and I'm lovin it every day! I have some pretty cool mods and am happy with the power. The only thing I'm not loving is the turbo lag. It's not bad, but it's there. What are people doing to decrease turbo lag and/or increase throttle response. Thanks!

 

Twin turbo, or super charger.


And before you ask, yes you can super + turbo charge.



Or if you want a cheaper option, intake, downpipe, and importantly an upgraded manifold. Basically anything that increases airflow

 

I heard about those twinturbo-blown Evo's...there nasty

 

bump ^^^ help me with this turbo lag! What about headers? My friend's ix has way better throttle response/spool up and the only difference between his IX and mine is that he has headers and I don't, and I have an ETS intercooler and his fmic is stock. Would headers like the AMS exhaust manifold help spool up/throttle response? I also have cams and he doesn't. Could it be in the tuning?

 

Any upgraded front mount will increase lag. However when the need to upgrade fmic's arises the benefits far outweigh the lag. And why are you complaining about lag on a stock ix turbo. Pshhhh

 

Have you considered changing the settings on the cams to shift the powerband a little?

 

Man! It's hard not too when my friend's IX has such an awesome spool up. Slow spool is just embarassing. It's spool envy!

 

turbo lag on stock turbo? i'll show u turbo lag on my gt35r

 

BBK Lite with a 2.3L Stroker

 

That's way beyond my skill level. I'll ask the guy that does my tuning about it.

 

Out of your power adders here I think some of the best ways to increase your low end response will be:

1) an upgraded o2 housing like helix or something

2) an octane adder say methanol or aquire the mods to run e85 (pump,injectors, etc..)

3) general weight reduction will make off throtle appear more "snappy" (spare tire and so forth)


As a general question out there do you have a wideband sensor? If so what kind of AFR's are you seeing at spool up and at WOT.

 

if you have a stock bov replacing with an aftermarket bov will help it spool a little quicker. and exhaust manifold also would help!!!

 

Aw damn i forgot about that one ported exhaust manifolds do rock

 

The one word answer: E85.

 

How to decrease lag:

1) Drive car with huge turbo for period of time

2) Get back in your car

Temporary solution. Yes.




But seriously porting and tuning are your friends for reducing lag.
