MAZZURI headers to belgium part2
After driving a few days(150miles) with the mazzuri's a already did some pulls with my IS250 and my vector fx2.
First i want to say that the car sound is louder then before but not too loud.
The performance is changend!!! i Did not do a dyno but i tried to do a before and after together with the vector fx2.Here are some first results
BEFORE ,Best run
tank 1/4 full
0-60 7.22 sec
1/4m 15.58@91m
AFTER
tank 1/2 full
0-60 6.80 sec
1/4m 15.15@93m
(did not want to post in other mazzuri thread is more a IS350thread)

wow that's impressive. did you feel that there was more power?? also how is the engine check light comming along? On the other thread? the is350's were having problems such as misfiring in the engine... are you having any of these problems?

Just did the install and everything was ok!!No problems yet.
I feel that the car has a flatter torque curve the extra push around 4500/5000rpm is gone .i think that's because there is more power/torque before 4500rpm ??

I try to have the same conditions.But for the before i did more then 10 runs and took the best.the after is only my second run.I know that weather can do something to performance but not in that way.With turbo engines it does,that's what i have been told.
If you know the dates of the runs you can look up the conditions online usually
(Not to say yours -are- just from weather, but it's a pretty large factor in performance)

I suggest you check Caymandivers drag journal...you'll find differences like yours -just- from weather on the 2IS. Compare his 6/1/07 run with his 4/6/07 run for example, 0.3 second difference in the 1/4 mile and almost 2 mph difference in trap speed, and the only difference listed was the density altitude due to weather

All these tests are very good!
This is some great feedback on the headers
If you could do tests at different temperatures and amount of gas in
the car that would be awesome! I think I've replied to your posts on my.IS
The 0-60 has substantially improved, and the power curve you speak of
will most likely be visible on a dyno.
Thanks for the updates!
I want these header now!

Any more 1/4 mile or 0-60 runs?
It sounds better than I thought
