Took my 91 ZR-1 to the dyno today

[Neat]

Made a trip to RPM Motorsports in Garner, NC today to strap my 91 ZR-1 to a dynojet 224 chassis dyno.

We made 3 pulls with the power key set to "full" and one pull with it in "normal" mode. The car made 371 RWP / 354 RWTQ on the third pull. All three pulls were within a couple HP of one another. With the valet key on sissy mode, the car only made 239 RWHP. Over a 100 HP difference, it was pretty wild to see the difference quantified like that.

It's kind of a weirdo car in terms of mods; it has:

DRM intake cams
Extrude honed plenum
Haibeck chip
Borla catback

It's still on the stock exhaust manifolds and catalytic converters, which is probably holding it back some. Overall though, I'm very pleased with the car.

PS - the guys at the dyno had never seen an LT5 before. They were impressed with the car, and were shocked when I showed them they could turn off 132 RWHP with the little key in front of the shifter.

Here's a video, the car sounds amazing in my opinion:

I was sort of surprised / impressed by how little the engine moves when making a pull. It was ran from 2000 (or so) to 7K, and if you watch the engine in the video it doesn't wiggle, rare up on the drivers side, nothing. With no audio and not being able to see the back tire, I don't know that you could tell the car was even running.
