Chassis dyno (why so expensive)

[Jason Heffner]

Dynojet makes one that is under 20 k but it will only do up to 500 rwhp. The dynojet 248 I have was around 28 k, 5500 for the hole in the floor, 1000 for the pit covers, 3500 for wideband oxygen sensor, 1000 for the computer to run it, 2500 for shipping, all in all ended up being about 40 k.

Yes, I bought it directly from Dynojet. It will handle up to 1200 rwhp.

Ours, as well, was purchased directly from Dynojet. It surely is a big investment, but one that's absolutely mandatory when tuning vehicles. If you're not using a wide-band O2 when tuning a car, you're just guessing. This is especially important on Vipers, because they vary so much from one to the other.
