Suspension Mod Question

[Steel2686]

I'm going to have my car dynoed in the Spring. The only mod I have now is the exhaust, but I plan on getting a couple more before late April when it's going in. I'm just going to go with the SLP airbox and bellow, plus a couple suspension mods (STB, SFC's...).

My question is, how much will SFC's affect RWHP numbers on the Dyno? I know they help to give back some of the lost HP by putting more down at the rear wheels. Is this something that won't really register as much on a Dyno, but will be a bit more noticeable on the street?

Also - With the mods listed, what kind of numbers should I expect to see?

Thanks in advance.

i don't think sfc's will add any power or help put any power to the ground.

SFC's do help put "power to the ground" somewhat by eliminating chassis flex. This helps to plant the wheels a bit, but you wouldnt see any difference on a chassis dyno. SFC's will help handling and may help a bit at the track to plant the tires, but their main purpose is to keep the drivetrain from twisting the unibody.

Technically, if the body "twists", energy is consumed. But it isn't enough to be measurable on a chassis dyno, IMHO. Don't worry about it.

It's kind of what I figured. Thanks everyone. I'm still going to go through with the SFC's, but I just won't look for any signifigant increase in Dynoed HP.
