Does anyone have some proof that the Popcharger or Nismo intake has improved your 1/4 time ?

Sound clips would also be much appreciated.

 

What's the best you can really hope to get at the wheels 5rwhp? That's a 2%gain. You think you can accurately measure a 2% hp improvement? No way. There is too much error in any every day drivers driving for that really to show anything on a 1/4 mile. My $0.02

 

Agreed. You gain/lose too much time with your pedal work and/or shifting to notice a difference with an intake.

FWIW, the Nismo sounds better than the JWT.

 

it might not affect your et, but if i understand correctly it should show up in your trap speed, even if you butcher the launch

 

Nitrous yeah... and if you butcher your launch, it'll show up in your trap speed for sure

 

Drag racing takes practice but eventually the average will show an improvement --- but for 5whp in a 3300lb car it would be lucky to show maybe a tenth off the ET

If the car was lighter 5whp would have more effect so focus more on the sound --- I have yet to hear either so I am still debating which one to get for my 06

 

you will improve .0000005 seconds and +.00000067 mph

 

That a question for me ?
If it is.... then yes, and my question to you would be what does that have anything to do with my topic ?
Thanks to the guys with insightful replies.
