Contour Enthusiasts Group Archives Forums Modifications Duratec Performance AFE Filter compared to competition + Pic's pg4

Dan if you look at the chart you will see the AFE has a big HP advantage over the Monster Flow from start to finish. The initial high blimp at 2.0-2.5 is the AFE Filter, not the Monster Flow, the only place where the Monster Flow showed some recovery was at 3700-4400 RPM. As far as the Tq curve, there can be numerous factors also including ECU. I don't know if John reset his computer prior to changing over to the AFE while dynoing, but that's a definate must as I found out with my Roar to AFE conversion. I felt there shouldn't have been much of any difference in airflow between the two, wasn't the case, the AFE was flowing much more than the Roar (by airflow readings on SAFC) that after I resetted the computer the difference was immediately noticeable. Dan I personally felt a definatel lag in the lowend on my car prior to resetting the ECU, but after I reset the computer overnight, traction was an issue!

Dan think about this for a second, if the Monster Flows flow capabilities are not the greatest, when the secondaries open up the demand for air will increase nearly twofold and will have less an ability to keep up with the demand, the AFE has no problem with that, in fact that was top priority in it's design. The Charts are real, the dyno was real and there's no ?ing a dyno, especially a reputable one. Just keep in mind that if the ECU wasn't reset for the AFE, that could be the answer right there as well and so the charts are really inaccurate as numbers would have definately been higher all around for the AFE...Sorry for the long Post

jcboekl you are on the right track indeed. That's what I'm trying to make who ever's reading these charts understand. If a filter creates enough backpressure than you will get an initial tq jump, tq and backpressure go hand-in-hand! The AFE was designed to minimize Back Pressure. Comeon Guy's if you spoke to someone who actually RACES on a regular basis (someone like me), I would tell you, 'Why would you be so concerned about driving this High Revving Motor in such low REV's, I sure don't!'

Micah,
Got to work today and saw my filter waiting, I installed it at lunch at took it for a drive!

I also added a new (used) Superchip last night for the SVT that I got form Kaisers turbo SVT. I am so pumped now!!!

The AFE Filter is about 2x the size of the S&B it replaced. It loks HUGE and seems to flow a LOT more as I hade to richen up the S-AFC 3% all across the board!!!!

I'm doing very nicely now.

Now for the 18's, camber adjustment plates and Mirko. Yes!!!!

Good to hear that STAZ!!! I know the Filter will come around, it's just a matter of time. Like they say, 'Out with the Old, in with the NEW!' By the way Staz wheather the Filter was big or small, the Filter just flows so well. With that size Filter you have, you're good till about 700hp ....If you ever get there.

By the way guys, Did I mention I'm working on bringing Skylines into Hawaii. Hawaii and Japan relations are very good and it's been an idea for awhile, some changes will need to be made to the car to make it legal for the US but Motorex (US supplier of Skylines is just a Ripoff) I hope to have my R33 GT-R within a Year, and NO, I'm not selling the SVT, they'll both have there place in my Race Program under MACH 2 Motorsports....

MMMM Skyline *GurgleDrip GurgleDrip*


How bout an R35 (When/If they come out)

Cool graphs. Since I drive like a granny, I'm keeping my monsterflow...

No high rpm use for me until the DMD goes in...

**Rubbing the Green Paper** R35, for you, sure!!! Like Jeremy McGuire said, "Show Me The Money!!!"

I'm Sticking with my R33, I like the look of it better and I won't be carrying a debtttt to my grave

When you're running up to 7600rpm like me, go ahead give me a call

Oh you didn't know! I plan on selling my body (Man whore)!

Kill joy here...

BTW - that's spike at the end doesn't count as real power made.

You knock that spike off and you have an average ~2HP/1TQ gain
