a-1000, 6x .018's and n2o install

[Cschafer]

Well I spent the last two weeks workin on the truck. I bought a used silver bullit (66/74 .80ar) so I caould still make the dyno meet this saturday. I fliped the manifold and built a wastegate adapter. Rebuilt all of my cac tubes, put two stages of nitrous in the hot side tube, removed the afc lever and installed 366 spring, customized the throttle linkage to get real full throttle, built a co2 spraybar for the intercooler, turned in the fuel screw a lttle more to the verge of run away.

I set the wastegate up to be electronically controlled by a hobbs switch and come on with the nitrous arming switch. I left the timing stock to try and save the head gasket so I'll probobly lose some there.

After working out a few bugs the truck is real strong I think. Even with the bigger turbo I can hit about 57 psi now with the afc out and it is still fogging black bad. With the throttle mods it is still full fueling at 3600 where I let off. With the wastegate on it limits to about 42lbs. I havent hit the nitrous yet. I wanna see what it makes on fuel first and if all goes well I'll bring in the nitrous one stage at a time. The meet is this saturday so we'll see.

Wow, sounds like you have been busy, im liking the mods, cant wait to see what you dyno

That sounds like a sweet setup. I'll keep my fingers crossed for the headgasket. Don't forget to post the dyno results in the dyno results thread.

well not exactly what I was hopeing for but the truck is still together so I guess I can smile.

1st run fuel only 356hp 753 ft lbs. Boost hit 55lbs ran great, never cleared up the smoke.

2nd run fuel only, couple less hp didn't brake it to help spool. 352/740

3rd run 1 stage, wastegate set to dump at 30lbs hit 57lbs made 424hp 900 ft lbs

4th run 2 stages, pegged 60lb guage, made 487hp 1005 ft lbs before poping the fuse for the fuel pump at 2550 rpms might of cliped 500 but barely. Smoke cleaned up pretty good but still had some left.

So now what's the problem, I have huge amounts of air 55lbs on a low,low drive pressure turbo and huge amounts of fuel that is still not being burnt. I'm gonna guess the timing is the problem not giving the mixture time to burn. That and it's the only thing I have yet to do.

Oh well it was fun all the remus boys did well, Adam Cornell uped his record to 1374hp, Kevin Chaffey hit 908 and a monster vp truck they just built hit 651 with single turbo on fuel.

I'll get some pics and videos up as soon as I figure it out, if anyone can help with that pm me.[/img]

Here's the graphs and the video of the nitrous runs. The fuel runs are the youtube link.

Advance your timing.
Do you have an accurate way to check timing?
I would do only this adjustment and take it for a test ride.
Your boost should drop 3-6 psi.
