You and your friend both have TD exhaust, and both have intakes, only his is a much shorter and direct path. WHen you both hit it was it an even start?

If so and he pulled ahead at first it-Im going to say it was because of his intake. Imagine having to suck in water through a long a$$ straw(your CAI) or a short one(his pop-charger), you will finish the cup with the short straw first. Ive never really been a fan of CAI's, on my Z my pop-charger gained 10whp over my AEM CAI on the same dyno, both dyno's SAE corrected. In my experience when you punch it with a CAI @ low rpm's you get what you described, a slight bog, a hesitation. Try running your intake in short ram mode, and try the race again, I guarantee you wont feel such a pause in power.

Edit-I see you have also added subs and $hit (weight) that will slow your car down, especiallly down low....

 

LMAO and $hit!

 

If its not helping you go faster, or hurting your performance its $hit

No offense to any stereo guys....

 

I agree. No offense, but if you wanna be faster don't add weight to ur car! The whole point is to make ur car lighter. Lighter = faster!
Now about the intake, I hear all diff stories. I think they all add the same hp, give or take 1, 2 hp.

 

oh how we wish the world was the same

 

sorry i guys i know lighter=faster but i kinda bought the car the way it is so i have to deal with the system..... its pretty sweet might i add.

 

injen cai and exhaust are known to reduce power in the lower power band and then have a improvement highe rp.

 

I can almost guarentee that it's your Injen exhaust. 80% of the people who owns this exhaust has your same problem. People who doesn't, are running FI or a lot of bolt ons. In a way, this is because you have minimal mods, and you don't have enough backpressure to utilize the exhaust, yet. Therefore, getting a SC or TT will solve your problem

 

I didnt have this problem with my Injen exhaust when I also had my intake. I still think its his CAI, only takes 15 min to convert to short ram he shouild try it....

 

Ill convert it when it gets warmer out lol.... ill let you guys know what happends.
