Vargas S2+ E85 Maperformance Downpipe

This is Texas weather so it was 103 degrees and about 120-130 charge temps on the pull. Imagine what it will do in cooler weather. This thread is intended to show how much more power you can make if you upgrade your to a reasonable downpipe when upgrading your turbo. This is Maperformance Catted downpipe along with their catback exhaust.

about 25psi on this dyno run. I've been as high as 28psi (Peak)

Awesome! Sounds like an easy 400 RWHP setup on a cooler day. I wonder how my setup will do with crappy 91 oct gas augmented by WMI. I live in the Phenix area, so I'll wait until the fall or winter to dyno.

By the way, how do you like the DSS driveshaft? Is it the aluminum or carbon fiber version?

Like the DSS quite a bit works well and helps the car rev into higher RPM's quicker besides the safety factor of not having to worry about breaking it. Does pick up a little bit of gear whine noise but I've got a lot of stop the hop mods on my car as well that also pick it up. the Turbo Back exhaust is sexy for sure. Not too loud until you romp on it and doesn't drone.

Is this graph comparing stock downpipe vs map performance? Looks good.

Looks like it those are similar to my stock numbers with a tune.

I like the curve numbers, around 2500RPM he is making almost 100 more lb-ft of torque.

This was also about 103 degrees on the dash when I made that power. People in states in the north that are 10-20 degrees less would make more power. The Tune+ Dyno reads below most other dynos as well.
