I ordered the headers a few weeks ago and i already have them.Before they will be installed i'm testing out a few things to see what the difference will be.Inspired by the video "is350 in 4.9s 0-60" i ordered the vector fx2 for making some before and afters.
I know my car is "only" a IS250 but again in europe there is only IS220D /IS250 /ISF.The mods i already have done are K&Nintake/TANABE/eibach/workwheels19".
HERE are my first results done with the vector fx2 and settings done for the IS250.

0-60 7.55sec
1/4m 15.88s @88.1
est hp 225hp
Are this normal numbers or i'm i doing wrong??
After the instal off the headers (6 august)i will do the same again till then i will perform a new test every time possible because temp/wind will affect the results.

 

Yes, those numbers seem okay. I would look for the relative change after adding the headers and not focus on how acurate those numbers may or may not be.

I recently installed the Mazurri headers on my AWD and will be doing some of my own post testing. Probably around the end of August or so.

Regards,

 

Sounds nice!

I'd really like to see some performance results from the Headers.

 

Xhydra, what headers did u get? mazzuri or JUNTW? or something new

 

Oh no I haven't got them yet, I was refering to "edualc"
I want to pick up either one, I want to see what the performance gain in the IS250 is going to look like with the mazzuri, but I was also thinking about the JUN-TW Headers.

 

haha i dunno why i linked ur response i wanted to ask edualc what headers he got


so edulac, what did u get??????

 

sorry the mazzuri headers!
