turbo lag

[edlugz]

i recently did an sr swap, my cars running okay but the lag is killing me. i just wana know what simple things i can do to reduce the lagg

Well, what do you have? Full 3" exhaust and intake would help, maybe a boost controller.

[edlugz]

well its totally stock, i only have a test pipe. any recomendations for an exhaust? how would a boost controller help?

Lag is lag. Without increasing exhaust pulses per cycle (IE adding cylinders) or increasing the strength of the exhaust pulse (Increasing displacement or focusing each pulse so that it hits the turbo at the best velocity with a twin scroll setup or equal length runners). Lag is pretty much at a minimum if you car is functioning properly. If not, check for boost or vacuum leaks.

stock turbo should hit full boost at about 2700rpms

[edlugz]

yea i hooked up a gauge. it does reach 7lbs early but the power doesnt seem to kick in untill 4k rpms

[idahotuner]

yea i think you should be looking fora vaccum leak or soemthing casue that isnt normal

[Spegt]

if you are feeling laggy and you just did your swap, check your timing. You might be too advanced.

Sounds like you have other issues.

[edlugz]

im still running the stock fuel pump and filter, so im gonna swap that out and see what happens

[idahotuner]

good cal lsee waht that does

im having the same problem.. its not lag.. does it feel like the motor isnt keeping up with the turbo? the turbo hits its max boost and the car bogs a bit and when u hit a certain rpm then it takes off.. i dono wtf is goin on

Sounds like you are having issues with your knock sensor, check your ECU codes.

Sell your car and get an LS1 camaro.

A full exhaust and intake manifold will help out a lot... Probably the best way to explain this theory is "full ins and outs". A better flowing intake manifold and better flowing exhaust will improve your spool x2.

The Faster air gets into your motor through your intake manifold and out through the exhaust manifold and turbo and through the exhaust pipe provides for a better spool which equals more power...

When I first did the swap the car was so sluggish I didn't even think the turbo was making boost'

So ya what your going through is natural unless you really do have something wrong. I hope this helps and good luck.
