Understanding Gains... looking for DP's + Full Exhaust Dyno's on Stage 1 Agg Cobb

rbsileighty · 11-17-2011, 04:52 PM

As stated I'm looking at mods and their gain potential. I really like Cobb and have it on my car so if someone could post up dyno results of dp's + full exhaust I'd appreciate it as most of the graphs have stock exhaust behind the dp's (dynojet is what I have access to here in town so that would be great).

Thank you for your help!

a dp back wont give you much in terms of power. maybe 10 whp max? dps and ic are the most important parts to change in order to run more aggressive.

Interesting, what is it worth in terms of tq?

You want gains?

PROcede V5 (pick your piggy) + Meth is the best bang for the buck. This alone will net you near 400 rwhp. Down the road add in DP's, FMIC, Exhaust.

I'm trying to understand what the gains found by exhaust would be on their own with Cobb stg 1 aggressive. I had seen the dyno thread but from what I saw no one had exhaust behind their dp's but it sounds like that doesn't make a real difference anyway

Terry from burger tested a set of 3 inch d.p's and gained almost 30whp!

Truth here.

For the Cobb guys hopefully they release the race maps to take advantage of methanol. I'm not sure where they are on making it public as it needs some refinement.

On Cobb stage 1 you aren't going to get near as high of gain with the mods as you will with the Stage 2 or Stage 2+. Stage 1 is supposed to be designed for a stock car so its not going to take full advantage of the mods. Mods allow you to push the car further which in turn results in higher gains. I think DP's are the next best thing to a tune, followed by Meth. In its current form though, you will get minimal gains from Meth since Cobb isn't currently mapped to support it.

Bang for buck, exhaust is probably the worse mod in terms of gains for this car. Cobb doesn't even require it for their Stage 2 tune though it is recommended. At most I would think you will see around 10 hp gained but the sound is where the exhaust earns it's $.

Take a look here to get an idea of approximately what mods will net you what HP. I know this dyno was done using Procede but I think it will give you what you're looking for.

That's very helpful thanks JStang! I would have expected a bit more from those dp's... but it looks like that car was already making quite a bit of power for basic bolt-on mods by that point anyway, definitely good gains none the less. I wonder what happened with the tq from 2.7k-3.2kish, looks like the dp's lost tq there which is odd... guess it could have just been a different roll-on by the dyno operator though
