Thanks Mike I think putting the stock muffler back on hurt a bit though. FWIW I monitored the AEM boost gauge as well, it's hitting 7psi vs. the 7.5 - 8psi on the DJ reading, it's amazing what .5 psi can do.

In my case, my boost fluxuated far more than Drew's, that's why I adopted the fitted curve approach. Drew's boost does not fluxuate as much as mine ...

fluxuation (def): having unpredictable ups and downs, this could be a change or variation in a quantity over time.

I read this as boost oscillation. I'm sure you know you should not have any. How come ?

[MarvelPhx]

CFM output is linear in any gear driven SC setup. The differences and variation of boost through the RPM range is mostly based on vanos configuration and throttle control. Some engines (like the 4.6L I assume) benefits from more overlap in some areas than other. If you look at PencilGeek's torque curve it is very smooth and strong throughout even if boost varies, this indicates advanced vanos calibration has been done to optimize VE vs filling in the various RPM ranges to achieve an optimal and smooth torque curve.

Drew nice gains (again) I really like the fact you picked up an extra 9 pounds of torqueGreat job man keep it up! So my car is at the shop having my kit installed. I dynoed my car on a Mustang dynamometer, the best run was 349.7whp. My vehicle currently has Fabspeed HFC's/resonated x-pipe with a Gintani race rear section and an Evosport pulley. What do you think I'll put down after the kit?(should we start a pool?)lol

Nice gains over EI xpipe!!!

Good move brotHer!

Either way I made more with the Gintani Catless xpipe/Stock Muffler combo! I think with the Borla back on or another HFE, I'll pick up a bit more.

Here's the results in all three CF's, I gained around 15 peak WHP, but as much as 22 whp gains at spots throughout the P-Band!

DREW.

are the number increased just on the x-pipe alone? that is an awesome gain for just a x-pipe swap!

a big congrats!

nice numbers !!!
i just put the dinan xpipe and you can really feel the difference..

Thanks buddy. You are correct, that is just the xpipe, but twith the stock muffler in place of the Borla I think it would make more with the Borla, I may redyno soon.

Thanks man, congrats on the Dinan xpipe it's a good piece. I may get the Dinan muffler cause the stock/catless combo sounds kinda weird, lol, Larry (biglare) says it doesn't drone and is quiet when cruising.

Drew! I've been hearing kill stories of you taking out GTRs and some other heavy modded M3 during Mfest.

if its true good Job

The heavily modded M3 was not at it's full potential but the runs were very close, the GTR is such an awesome car, fun times.

I hope you brought your DV cause I am subscribed to your youtube account

I heard Brian did the 2nd fastest lap in his Gintani Set up!

Yup, there is no drone at all. Driving back to Phx today was nice and quiet until I kicked it down a couple of gears to pass some cars!

BTW, great to meet you on Sat. We'll have to meet up again next month when I'll have my car in SoCal!

[m33]

i wasnt able to make it , sounds like you guyz had some seriouse fun , would have been nice to meet u guys !

im running the dinan xpipe with stock exhaust untill my dinan exhaust comes and boy that thing made a seriouse difference compared to the meisterchaft gt2 ...
when boosted you really need back pressure and it looks like the dinan setup does just that ,very well blanced

Special thanks for Roman and Larry for pointing me in the right direction

You coming to Bimmerfest?

Larry or M33, if you guys can, please do a vid with the Dinan catless exhaust setup! Inside cabin and out!

[TheKosherStogie]

great vids drew!!! cant believe you raced a highly modded gtr and hpf stg 3 and won....even if the hpf car wasnt on race gas still very impressive!!!

Thanks, I appreciate that! Looking forward to seeing more stuff about your car as well.
