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!

 

I really want this exhaust system. When will it be released?

 

I WAS TRYING TO RELEASE IT ALREADY BUT RAN INTO SOME OTHER PROJECTS THAT TOOK ME OFF THE EXHUAST. BUT NOW I AM GETTING BACK ON IT SO I MIGHT LET IT OUT AT THANKSGIVING.

 

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?

 

that exhaust will kick some ___...JON...thanks for the intake...and i cant wait for that exhaust...(another happy customer)...

 

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

 

WHEN WE TESTED IT I WAS AROUND 85 DB'S. AS THE STOCK SYSTEM HP MY CAR WAS AROUND 88.7WHP.

 

wow. almost 15 whp gain just for an intake and exhaust. Just imagine adding headers, net hp gain will be almost as much as a blitz supercharger but a fraction of the cost.

 

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

 

is there a freeway drone @ about 3000 rpm? Is there some type of resonator?

 

NO AT 3000 RPM'S THE EXHAUST IS AT 88DB'S IT IS VERY LOW TONE SOUNDS NICE.

 

sounds great, when and where and how much?

 

STILL WORKING ON THE PRICE I AM TRYING TO KEEP IT AROUND 350 TO 400 FULL RETAIL, IT IS A MANDRELL BENT PIPEING AND TIG WELDED. WE WILL HAVE SOME PICS UP MAYBE BY TONIGHT.

 

Well, what if the piping is 2.25 from the header back with high flow Cat and High flow resonator? Will the cure the funny motor surge your talking about?

 

mmm. 2.25 all the waythrough would work fine. Like a stylis exhaust system! J/K SPFRBOX didn't mean to take the spotlight away.

 

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?

 

Are there any pictures anywhere of the intake yet, looked but have not found!

 

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...

 

Are these going to be available for both cars?

If so, I have an xA, and have been waiting for a nice setup to be available.
