I took it to a track once, the 15.7@87 hp calculates out to around 150 - 160 rwhp, based on the weight.

The DCOE 40's do have 36mm chokes, they aren't really quite the total determining factor in how much air goes in, but those are larger than typically setup on a pair of 40's. I got my 40's set up for a B18, they had 32mm chokes.

I did the 'top speed run' on a level piece of road. It took a modest amount of time to get up to speed, and by the time it kissed 6500 on the tach (the speedometer is wildly inaccurate, it was pegged past 70 mph anyhow) in OD it wasn't accelerating very quickly any more.

Wind noise was epic in nature, but really, the PV felt very stable, the steering was calm, the car wasn't wandering, it just felt hunkered down. All the windows were shut, and my PV has no rear view mirrors.

It might have gradually gotten a bit higher, but traffic that had previously been *way* ahead was approaching, and I sure wasn't going to fly by anyone at such a speed, so I lifted.

I think I had a Volvo 'R' cam in it then, now it has an Isky VV81 (one step peppier than the VV71 IPD sells as their Street Perf cam). I'm not sure if it has less power or not now, it sort of feels like it.
