Sorry it's taken so long for me to get on here and give you guys the details, but I'm not behind a desk all day anymore, instead I get to build motors and work on trucks, the stuff I really love to do!!! So anyway, I'm limited on the time I have on the computer, but I definently wanted to get on here and take the time out to say thanks for all the support! :hug:
Anyway, the weekend before I made the dyno runs at meridian motorsports I ran 11.67 @ 118 mph on fuel only and ran 11.255 @ 124.77 mph on the spray. Now when I got back from the DHRA nationals I dyno'd the truck with the same setup and nitrous jets that I ran in utah and put down 938hp on our superflow, it also put down 757 on fuel only. I then changed one jet from a 41 to a 99 and put down 1034hp and 1755 ft lbs on one stage of nitrous. I decided to hold off on hitting it with both stages untill I went to the meridian dyno day, that way if I did blow something up it was for a good audience!!
Anyway, I have some changes that I need to make to the truck and setup to really get it to run this kind of power, one of them is the valve springs and retainers to eliminate valve float at the upper RPM and need to add a roll bar for saftey. I've been lucky so far and don't wanna push my luck with a truck as capable as mine.
But with any big HP build there are things to learn from and changes to be made, whether or not I step the bar up in the future is yet to be determined. One thing is for sure, I'm definently not hanging up the towel, I enjoy this waaaay to much.
But thanks again for the support guys, I appreciate it!!
Cheers,
Wade

Sup Wade! Did you start your own shop? Where you located? How do i get ahold of you now? I lost your old number.
Congrats Wade. When you call tomorrow if I don't answer it is because I got court. Leave a message I'll call u back. A buddy bought a new D-max in Idaho and saidthat he might stop by your guy's shop.
Hows Parkers old truck treatn ya? It was fun watching him pull with it at the sled pulls. He has alot of time and money in that thing. Let me know when your ready to run them

All in time. It has alot left in it for the strip but need to pull the 100hp sticks out and get some smaller ones. Needs cognitos, centerlink and a tune. He kept the EFI. It's real dead until 2300 rpm then she will light off. Ran 12.3 in Denver in sled form so that ain't to bad I guess.
You ran a 12.3 in it? Timeslip? What do you mean he kept EFI? He pulled all the tunes out and kept his V2 controller? Weird he didnt leave you a street tune.
Parker ran the 12.3 at truck fest. The tune that is in it is for the s400, 135lph injectors and high stall tq convertor but all that is on the shelf. Haven't had time to work on the truck yet. Taken it out twice and it runs good but needs a better tune. Truck is real hard to spool. Been working on getting the motor in the 01 d-max. Got any stock injectors?
