I have to admit, that I was concidering that upgrade in the near future until I saw an episode of Two Guys Garage in which they installed Roush Intake. I thought I'd get that one. But I don't do quarter mile, I do however race my friend from time to time against his C5 he keeps Modding so I add **** to mine to stay ahead. Half the time I don't know what I'm doing. That's why these threads are educational, atleast for me.

No ****in' way. Sad that you had to lose $$$ to figure that out - I could've told you that months ago.

Thanks for the well thought out and informative post.

Speaking about redline, are you using a tune that increases your redline to 7500?
If so, what is the torque like at that lat 500RPM bandwidth? Does it help in allowing you to hold onto a gear a little longer before shifting to the next gear?

the last 500-1000 rpm goes by so fast i dont even know whats going on haha.. but yes, i think its set to 7500. I could mostly hear the difference more than anything, engine really screams now. as far as feel I dunno.. most of the time i have to let off because my rear end is coming around on me.

Hey Guys,

I don't want to hi jack the post but we have seen some great gains with our Boss intake with our CAI, Tune, and stock exhaust. The gains were very noticeable. Here is our Dyno sheet with all the mention parts.

Expect peak power gains in excess 50 horsepower over a stock GT on stock exhaust. With the Boss intake top end power never falls off, giving you a car that just keeps pulling hard shift after shift.

Just wanted to give you guys a piece of mind if you are considering the intake.

ive had this conversation with a few people. i don't think most folks will miss the 10 wtq you lose, you will feel the power up top though. i still think most of the benefit for this is road course guys since as you can see the peak power is very flat through a wide range all the way to redline. flat power and torque curves are betting for road course work than peaky curves.
