Thanks guys, here's what I recieved from Ed and this is what it is for now!

Dyno based off of RPM



Dyno based off of MPH

This MPH dyno chart makes NO sense at all to me, I can't even interpet the real meaning behind it.
I'm also not sure if these are corrected or uncorrected numbers, so Ed would have to answer that, along with any correction factors and enviornmental conditions at the time of the pull.

Thanks Jim........At this point Will and myself are going to go down to Portsmouth to pick both of our cars up tomorrow morning. Will is going to trailer back, I'm going to drive mine back. I'll do my best NOT to get a ticket NOR break down on the side of the road ( doubt that'll happen). I'm going to do an Oil change ASAP, run the tank dry and run a few tanks of good super 93 with maybe some octane boost for a week or so, then try to see what happens after that. I'm happy that it's showing signs of being strong and I'll FINALLY drive it tomorrow and see if the SOTP makes me want to SH*T myself like I hope it always would!........Besides, I've never OWNED anything over 350hp before, so I'm sure it'll be a SHARP learning curve reguardless of WHAT IT IS!..... I'll see if I can get some data and figure out what's going on in the tables and also look into doing some data logging for the car. I'm TOTALLY open for suggestions as this appears to be a work in process for refinement. I spoke to Will and he's pretty happy with what he see's and believes that the motor is doing exactly what he wanted it to do. He wants to look into the hiccup and see where the source is and how severe before anything else! Either way, I'm in Portsmouth in the morning and I'll post my drive results tomorrow night when I get back home!

P.S. The bold type is for Rick, Jon, Jeff and anyone else that I snuck in and out of town on!........LOL

Well, Will and myself drove down today to pick up the car's.......and left with only mine. There were a few issues when we got there.
1. Under hard acceleration the car bogged down REALLY bad!
The car was out of gas......took it to the gas station and filled it up with 18 gallons, fixed that problem.
2. Throttle would stick open or rev up to almost 1500-2000 rpm once the car was hot
Cooling issue
3. Excessive oil leak from the bottom of the motor on the drivers side
This was due to the bolts in the oil filter adapter backing out and were loose
4. Car was overheating
Cooling system was in need of a serious burping
AND my Mezerie HD EWP was running backwards (Never heard of this one before)

The waterpump was wired with the Mezerie relay kit and the relay had the Orange (Constant hot) wire and the Blue (Pump Power) wire's crossed on the relay. Once I rewired the relay we were able to properly purge all of the air out of the system and she ran GREAT all the way home. This was identified when the waterpump was running, it was pushing water out of the coolant fill, vice sucking it down.

As far as ME needing a diaper, I think mine is still full and I'm not too sure how Rick (PDQUIK95) is doing, but besides the finger nail marks he left in my dash and the smell of poop in the car when I stomped the gas on the way to and from the gas station all went well! Thanks for showing up Rick helping out with the car to get it home and it was truly a pleasure meeting you.

There is still a leak of oil from the valve cover gaskets that we are going to fix tomorrow and I did not drive the car back home. I left that honor to Will, who PROUDLY showed me just how much 383rwhp is!........LOL (That's offical and I have a dyno sheet to prove it!) I also believe that he did not feel any ignition dropouts or missing with the car from his drive, but I'm sure he'll enlighten us. Just as a disclaimer, I've never owned or have driven ANYTHING this powerful before and I've driven ALOT of cars. I know there are bigger and badder out there but this car EXCEEDS my driving abilities EASY. I plan on taking it to the local track in Manassas this coming up Wednesday and run it through the 1/8th mile to see how it performs, besides that I plan on driving it and keeping it ON the road and in one piece.

I expect Will to add more information on how the car drives/performs as I have nothing to gauge this upon and my experiance is very limited at this time. Will seemed very excited and complained about the noise level that my Power Effects exhaust (He's a Corsa dude) made. I think it sounds great and I still have the can's wide open. The computer indicated that he was getting ~30 to 32mpg on the way back home on the highway and once the tank is drained, I'll compute to see if that is right on or not.

I'll post some pictures and video's tomorrow and close out the thread. One for the things that I MUST do is to thank ALL of the CF members that helped, advised, directed, lurked and even annoyed me LOL, during this build. Without YOU this would have NEVER been possible and I REALLY appreciate ALL of the help, input and participation in an unforgetable Journey.

Sincerely

P.S. You Guys ROCK!
