Grateful thanks to Mark at Abbey for a spin in their supercharged ginger ninja.
The best way to describe how it feels to me, is like a decent sized V8. Very different to Dave's turbo which while I really enjoyed it, (and it has a fair bit more grunt) I just preferred the delivery from Abbey's Harrop. In it's standard tune, as-is, it's not mid-blowingly quick but has a great surge of low-down grunt that builds and builds. It's plenty fast enough for my needs and I'm sorely tempted, but haven't decided one way or the other. Yet.
If I could have two cars on the drive, I'd do it in a heartbeat, and keep a NA and get a S/C car too. I'm just concerned that I'd miss revving the tabs off my NA engine - I really enjoy it the way it is. It's just the rare occasion when it would be nice to ride a wave of torque from what feels like a lazy, yet urgent V8.
At the moment I'm a definite maybe. It'll be a month or two before I make a decision anyway - plenty of thinking to be done.
