Riss Racing Axle Back Dyno #'s

Hey guys, well as I've been dynoing just about everything we can get for these cars, I finally was rewarded with some great gains!

Before Dyno: Car made 346 RWHP 252 RWTQ

After Dyno: Car made just over 360 RWHP and 260 RWTQ!

It was nice to see a bolt on set of Mufflers add 14 RWHP & 8 RWTQ.

You can also see the TQ below 3,000 RPMS is considerably more... and is what is most noticeable driving away from the stoplight.

When I added these mufflers, I'd find myself 'forgetting' to put the car right into M mode... because it felt so strong & responsive down low!

I've now sent my ECU to PowerChip, to get their Flash Tune, and will try to get back to the Dyno to post those gains in the next week or so.

The Riss Racing Mufflers do have some drone noticeable inside the car. In speaking with some others... we've discussed the possibility, if DynaMat in the trunk would help to reduce it as well?

The sound outside the car is amazing, and the Dyno Gains are very impressive.

Peace,
Dave
