SPFR Cat-Back Exhaust & Intake Dyno Results!
I just spent a few hours working on getting the SPFR dyno results digitized from the fax Jon sent me this afternoon - I have included the original scaned fax if anyone want's to see it (since the colorized version is a digital re-make of the chart), but since it's kinda hard to read online, i spent the time making a color, digitized version for everone to check out.
so here it is, 2 runs:
1 with the SPFR Cat-Back Exhaust system
1 with the Cat-Back and the SPFR Intake
keep in mind also that these numbers are for the prototype versions, eric m. recently swapped out his prototype intake for the production version and said it feels even faster! i'll repost when Jon has a chance to re-dyno with the production model!

right on Jon, if you can get them out by then that would be great. I emailed you a while back to let you know i was intereseted. whenever you have the first batch ready let me know, I got the cash and am ready.
thanks,

I had TRD exhaust on my xB and thought that I lost too much bottom end with it. Does your exhaust have good bottom end? Do you have stock exhaust dyno runs to compare with yours? Also, the TRD had a loud inside drone @ freeway speeds, how's yours? If your exhaust is 88 Dbs, what is stock Dbs?

you can see on the chart that the torque is phat with this system, 105+ ft-lbs! (the 2 upper lines are the torque curve) as you can see it pulls stong all the way through the graph

NOT SO TRUE THE PROBLEM WITH THE HEADERS IS GOING FROM BIGGER PIPEING BACK INTO SMALL AND THEN INTO THE BIGGER CAT BACK SYSTEM. WILL CAUSE FUNNY MOTOR SURGE LIKE A BUBBLE MACHINE, WE CAN MAKE A HEADER NO PROBLEM BUT I DON'T WANT THE PROBLEMS. BY THE WAY I AM NOT YEALING I ONLY TYPE IN CAPS

It's hard to compare without a stock engine as a baseline, but it looks like the Aem intake makes h.p and torque from 2000 rpm and up. This unit makes h.p and torque from 4000- 6000rpm. The fact that the AEM dyno is without a exhaust may make a difference. I would love to see a stock "vs" intake only dyno. This intake must make h.p below 4000, the exhaust probably drowns out the gains so you don't see them on the graph. Overall the combined intake exhaust results seem great.
Is this a Dynojet dyno?

YES IT WAS A DYNO JET. IF YOU USE THE ENTER SEARCH TERMS, TYPE SPFR IN THERE YOU WILL FIND THE PICS. LOOK IN THE TOPICS SAN FERNANDO VALLEY MEET AND GREET, AS WELL SPFR INSTALL PICS V 1.0. I DID NOT SEE WHO WAS ASKING IF YOU WANT THE INTAKE UP THERE LET ME KNOW YOU KNOW HOW TO GET AHOLD OF ME...
