Switching from the X3 to the X4, going to see what it can do over the X3, will post results within a week when it gets here!! Man I can't wait!!!

 

Wow, what made you want the change?

 

Car is too slow

 

You gonna sale the X3 cam??

 

im hoping to have my x4 up and running soon too

 

DAMN good luck with it

 

Formula383 - Yep gonna sell the X3, got a couple locals interested, if they fall through are you interested? Has maybe 8k miles on it if that.

nspr8td lt1 - Let me know how it goes, I have a friend that has the X4 and his car runs strong!

Pdd - Thanks dude, I hope to gain some power all over the place, and hopefully run a little quicker

 

What are the specs on the X4?

 

Who knows, bigger than the X3

 

Heads, nitrous....quit messing with the wussy stuff..

 

haha, heads are too much money for the HP you acheive, and I will add nitrous too, just want to get the baddest cam first, then the nitrous will make it SHINE Heads can eat me

 

Isn't that the point, to put to gether a combo that matches? Heads would be a solid part of it if one wants to make more power.

 

Yeah but they cost a ton, and you get what, 40hp maybe, I can spend $600 and get 150hp if I want.

 

Let's see, people go from 400 to 450 horsepower with the addition of heads that cost less than $2000. That is $40 per horsepower (of course, give or take a few). And you can get cheaper heads if you want. Good stainless headers, for comparisons sake, would be $35 per horse if they gained you 20 rwhp. So I don't think it's fair to say that heads aren't worth the money. They allow you to have fulltime power (N/A) while retaining drivability by not running a huge *** cam. But if you would rather lose drivability by running a bigger cam to gain a little power, be my guest.

 

Who says big cams lose drivability? My X3 drives like stock, just fine, a good tuner can make a big cam drive great. I would do heads on a new motor, say a 408, but a stock bottom end no thanks. A nice big cam will make me happy, and nitrous will suffice in a bind.

 

What about pov clearance on your stock shortblock? If that cam is as big as I suspect it is then I suspect you may have a problem.

 

No clearance problems, it's made for stock heads.... at least that's what they tell us

 

I agree I streeted a TREX in an A4 in my daily driver. It wasnt bad at all

 

Possibly interested, let me know if the deals fall through.

 

orange peel post up how it goes. it should make for a nice comparrison between X3 & X4.
