Slim chance, firing up the car tomorrow and getting tuned on Thursday...I have signed up for SpeedVentures @ California Speedway ROVAL Nov 21-23 (all 3 days) which I figure will be the first serious test of the car. You should come!

Success! Fired up like a charm this weekend. Well kind of like a charm, I couldn't get it to fire until I put in a brand new set of plugs (doh) then it was perfect. Unfortunately a design failure on my part means that I need to swap the S4 waterpump housing on instead of the S5 I am using right now - the S4 has the radiator cap on top of the neck which is ideal for my v-mount setup. Right now it is impossible for me to bleed air out of the system because the radiator and cap are at a pretty low point.
Also when I swapped the main pulley some weeks ago I forgot to put the engine on its back, so I thought the bearing at the front of the e-shaft may have dropped. I decided to pull the front cover to check, luckily it was still in place and in perfect condition. I am going for tuning on Saturday assuming the new waterpump housing/waterpump/tstat/pulley arrives as it is supposed to on Friday!

****. Already ordered the damn thing and took the housing off (had to anyway I guess for the front cover). Thanks anyway, will bear it in mind for the future. Is there any flow difference between the S4 and S5 waterpumps?
I am loving the car, keep up the good work on a amazing machine!

Thanks!
I haven't updated in a while so here goes...
I've taken the car out a couple of times, and already rebuilt the engine once
We made 405rwhp @ 11psi last time on the dyno which is right on the ST1 class limit. I figure at around 20psi it should break 500 which is what I am hoping for this coming weekend.
I am still suffering from a fuel starvation/hesitation thing which, thanks to everyones advice, I think is either due to my having the fuel rails in series rather than parallel or tuning, or both. I'm converting the fuel lines to parallel tonight and will be on the dyno again on sat to try and recreate/cure the problem. It's possible that the primaries are starving the secondaries of fuel (thanks TrentO) which is what is causing the hesitation.
Next track event is on the 17th so hopefully I will have it all cured by then!
