HP/TQ claims of modifications

Papethova · 01-12-2009, 04:09 PM

Can we start a thread of all the claimed gains from various parts and manufacturers. A one stop comparison of all the various intakes or exhausts, etc etc so we can compare the expected gains. Preferably gains on a stock 135, but I know thats somewhat difficult.

Independent dyno results would be best.

Borla Exhaust

p# 11763 rear section = +8 hp/ +11 torque according to Borla
p# 12655 race system which deletes cats & therefore not "street legal" =
+24 hp/ +20 torque according to Borla

Also, here are the weight savings:
Borla p#11763 saves 15.5 lbs (Borla 14.5 lbs vs. 30 lbs OE)
Borla p#12655 saves 25.6 lbs (Borla 33.4 lbs vs. 59 lbs OE)

My personal dyno shows a gain of 12HP at 3800RPM and a peak gain of 7HP with the axleback. No dyno yet of the "race" system.

I have the BMW Performance exhaust and on the Dyno in Dec 08 (with an ITG foam air filter fitted) I Dyno'd 312 BHP but here's the weird one 480 NM torque.

480Nm equals ~ 354 lbs

That is an excellent idea. Looks like Borla is being truthful about their system which is very refreshing to see. Many of the products marketed towards us are the biggest F'ing lies I have ever seen. Big thumbs up to you for going out there and testing on your own!

I know.... its supposed to be 300Ft Lbs so it up quite a bit and I don;t know why. Not that I'm complaining as I would take Torque over BHP any day in this car.
