Fiat 124 Dyno Day ONE.

Time to answer a few basic questions including:

1. Baseline Power at the Wheels for MANUAL Trans Fiat124
2. Does change of muffler help?
3. How does Fiat124 compare to Abarth500 with same motor?
4. How does Fiat124 compare to ND Miata on same dyno?

Does muffler change add power? Yes, we hacked up a RoadsterSport Race muffler to make it fit the cutout of the Fiat just to get a test done, this muffler is effectively just a 2.5 inch straight pipe. Muffler adds about 5HP and 11 Ft/lbs Torque.

Fiat 124 BASELINE POWER...145 HP, 169 Ft/lbs torque.
Fiat 124 Change MUFFLER.....150HP, 180 Ft/lbs torque.

Comparison STOCK FIAT with stock muffler to STOCK ND Miata with stock muffler. This really drives home the comparison that the Fiat makes a lot more power under the curve and yet it is slower in all magazine 0-60 tests....figure a mix of factors including a bit of extra weight, gearing, lower redline, etc.

Fiat 124 with stock muffler, Fiat Abarth500 with stock muffler and SPORT button engaged.

Fiat500 Abarth with Sport button ON/OFF. Curious if Abarth124 gets a difference this big, Sport button helps the party get started earlier. From driving the Fiat124Abarth at the Press Intro day my guess is that we see something similar between normal 124 and Abarth124.

I did not see any results, just answers to questions on his forum thread. From pg.5 & 6.

It apparently didn't serve his purpose.
