Ok yes just because its track dedicated but I was not referring to track dedicated XB2's I mean this car is totally gutted out and practically weightless..... now put that setup in a DD and there is no way ( my opinion) you gonna get those #'s just saying

 

ahh finally a glince of hope wit some evedience to back it up lol.. thanx.. but im thinkin since u guys say im not gonna add alot of hp from just the bolts(which i kno) do u think the unichip (piggys r supposed to b crap right?) is helping out big time in the performance field.. i installed my strup 4-1 header nd unichip at same time and literally u could feel the gains.. it waz like nite nd day, intake u hear not really feel the power, maybe a lil on top end but not much(least to me) nd exhaust(didnt feel any diff just noise.. headers nd unichip installed same time, nd i went damn i feel something now lol.. my box really gets going around 4-5k rpm oo btw my unichip has the map for headers,intake, exhuast if that may help answer my ?

 

He's auto like me. IIRC 3rd gear tops out around 115mph.


I agree! The is250 is a dog! 204bhp minus 25whp for the AT and another 25whp for awd and 3500 lbs vs 3100lbs for the AT XB doesn't look good for the is250.

You're right but my main point was that, despite appearances, the XB2 only weighs 120 lbs more than a TC. Cory's XB probably weighs over 3200 lbs and still runs 12.8 in the 1/4. That's pretty quick for a toaster!

It's all in how you look at it. Obviously there are better platforms upon which to build a fast street car but IMO there's nothing wrong with buying a platform you like and making it faster and more fun.

 

Actually dyno testing on the XB has shown that a CAI provides a lot more hp and torque gain than a header. Here's a good link:

Here's a thread to watch for Unichip dyno results:

Based on your mods, I'd guess youre putting down about 150whp and 150lbs of torque which is pretty good for a AT XB that starts off at 126/128 at the wheels. More importantly, there's a lot more to going fast than peak hp/torque numbers on a dyno. A nice flat torque curve trumps peak whp any day...

 

anyone know of a dyno spot in the cerritos area of southern cali.. ill get a dyno and it will shed some light on the subject.. and prove wat kinda numbers im running

 

First: Learn English. Learn how to read it, then learn how to type it properly.

Second: xB2 is not a box, far from it, and has decent power to begin with.

Third: I'm hungry.

 

Cookies?

 

He's eaten enough.

Marlon, AIM?

 

Petros, sure
