So I am coming home in a couple weeks from Afghanistan, I bought a small pile of parts for my 2008 X GSR and I am looking for a ball park as to where the car will stand after a good tune as far as HP/TQ and 1/4 ET. Granted I know there are about 6 million variables but like I said I am just trying to get an idea of what to expect.


FMIC
U&L IC Pipe
Grimspeed BCS
AEM intake
Full turbo back exhaust (test pipe)
Stock wheels and rubber ( I am going to get a good gripping all around tire but nothing really purpose made )
I bought that blue fuel relay replacement (I read it was good to do so)
I have the stock DV and and HKS SSQV BOV (VTA) not sure which would be better to use.
I am planning on staying around 25-26lbs of boost or pretty much in the "safe area" HP/TQ for a stock motor.

 

I'm in Afghanistan currently (two more months to go) so congrats on going home. As far as the parts, are you going to get a tune? I would say around 300 or so

 

350 whp and in the 12s if you know how to launch her

where are you getting it tuned and what kind of dyno do they have?

 

Yep 350 is about right. I'm going to say 347 but only because I want to win the prize.

 

Well ihave two tuners i am looking at, one has a hub dyno and the other is a mustang dyno. obviously the hub will show more hp/tq but I'm going to shoot for 400, so I will probably add more boost, if thats the case. It will take time to lauch it right because I only put 300 miles on the car when I was home on leave. Thats for the input I will get numbers up as soon as I can. Any other bolt on parts you recommend?

 

From everything I've read don't VTA the BOV

Recirculate it.

 

I have the recirc kit already, just wasnt sure if it was a bit much for a stock turbo, sometimes less is more.

 

The bov is completely unnecessary for a stock turbo really. It's more of a sound factor at that point. You can use the stock bov for awhile.

 

And speaking from the experience the stock BOV is the best.

I tried switching it out and ended up coming right back to it lol.

 

youll make about 305 on a mustang

 

309.343333 repeating, like pi. HP. You'll make infinite HP but never 309.344...

Start with those mods, drive it a bit, then add more as you figure out where you want to take it.

 

I would guess around 315....

 

I'd say 350ish and in the 12's for 1/4.
