Cheers guys, you could say the last ten years of ownership have been very interesting and testing indeed. The great news is I'm nearly *there* with car and *myself*, as far as getting to know the car inside out is concerned - and am starting to enjoy the ZR-1 experience again. I took my fourteen year old son on a 120 mile journey last weekend and gave him the 'full power' 3 grand pull away while cruising. He loved it and his words were " Dad it sucks the air out of my lungs "
I took the car apart a few years ago having dyno'd it at 546 flywheel hp - I've since added a better flowing top-end with larger valves but am running it with standard cams at present and plan to locate and fit some more radical cams at a later date. I will also be fitting some 4.10's in the next few weeks along with refitting the 3" B&B which I took off because it was too noisey.
I've tried four exhasts so far, standard, Corsa, Borla and B&B. I found all except the B&B to be possibly too restrictive, and the Corsa too tinny at WOT. I can live with the Borla but again it's restricted so I'll explore ways of trying to make the B&B a little quieter without obstructing perfomance.
I'm also thinking about replacing the injectors for new ones although we don't have the dreaded ethanol in our pump gas. The Zed always gets the highest octane on offer too.
Once I sort these small duties I'll hit the dyno again.
------------
Keep on cruising.
