LET Motorsport Flash Stage 1 - First to dyno on this side of the States!

Today wasn't the greatest day to dyno a car, here is why:

Ambient temp was around 70F
Humidity was a power destroying 86%!!!

average for the area is 62%

Which explains the lower than average numbers produced. However the delta is what we are truely after here.

The car: A 2008 E92 coupe with manual transmission
Modification: None



228.7 hp
271.6 tq

LET Stage 1:

268.6 hp
298.8 tq

The LET Flash Stage 1 made 40 more hp and 27 more ft/lb of torque at peak than stock.

In the curve, it made 44 more hp! and 37 more ft/lb! of torque, great numbers for a flash running 11.7 psi of boost.

During some back to back dyno runs we saw significant drop in both hp and tq, heat soak of the stock intercooler was the cause here. We lost 18 hp and 12 ft/lb of torque at peak. In the curve, we lost 24 hp and 22 ft/lb or torque. By adding a nice intercooler, such as the Code3 Spearco unit will solve this heat soaking issue.

Retail price on the LET Motorsport Flash is $699.
