Re: 540 in the werx!
Today is Dyno day 
Brad ran break in last night and today we see where the A/F mapping is. Will likely have to send the ECU out for tweaking, looks like Dustin will do it, Mark is covered up.
For those who slapped me silly in this thread and elsewhere- thank you. The small delay and investment is worth it in peace of mind for quality time on the lake and resale should I ever face that day (used to lust for twins but not as much lately).

Re: 540 in the werx!
Cattitude , have fun on the dyno , it's the best way to get her set up right . Let us all know how you make out , give us some dyno results . I had Jo rig my dash with boost and pyro gauges even though I have a carbed 540 now I will be ready for a whipple or maybe rtech , I can't wait to see what your new motor will do in the boat . Got to go mid to high 80's right ? When will you splash?

Nothing worse than having to do a rebuild job than to have to do it a second time. Keep us posted.
My exact thoughts. Dyno is not just for numbers

Re: 540 in the werx!
Mapping was so far off/lean we could not run much past idle. Sent ECU to AS&M, ECU should be back this AM, should be Dyno'd today- will advise
I've been a way the last two weekend sso did not miss any boating- plan to splash Sat.

Re: 540 in the werx!
Well, we ran enough to get a good impression but could not get close to full throttle- the fuel system could not keep up and pressure was falling off. we did see 680-720 ft/lbs early in the mid range (before boost) and carrying high, hp got up near 680 , but again, part throttle.
Speaking with Dino at Teague (it was late and he hustled to ship me some parts next day from CA) he told me the P/N's I had for the aeromotive pump, pre filter and regulator were relativley good stuff, but automotive, mismatched and inadequate for our project. (All of that came with the new to me engine) So I bought a complete sytem from him which he recommended- same as they use on their Teague 900 EFI, will run later today for the bigger numbers.
Looks like it'll cruise with a bigger wheel on it though
Par throttole A/f at 3000 is a bit lean and will have to be recalled, the rest looks good so far.
Good thing we went on the Dyno- thanks again guys- posterchild story for why you should dyno.

Thats why I went w/ JC Perf/Zul. I knew I would't run into any of those problems.
I'm glad things are coming together for you.
Your boats gonna rock.
