History / Build

So,

I have had my 2004 silverado since 2008, and it has seen quite a bit of action.

It started life as a 4.8L v8, with ~300hp.

I also added a touch screen in-dash GPS / radio, remote start, automatic door locks, a CB, and some other fun toys.
It also had a 2400 watt amp with a rockford fosgate T-2.

Since, I enjoy going fast, within two years of obtaining it, I installed a supercharger on it, as well as a custom exhaust system. Shortly after, I blew up the transmission.
Here is a video:

So, After I drove it for a few more years, I ended up melting a few pistons...

So, by this time, I decide to go all out and rebuild the truck piece by piece.

The first step was to get rid of the old...

And build up the new.

So, once I acquired a new engine and transmission.... It was time to get started.

The transmission is a TCI 6x warranted at 1200hp.

So, lets toss all of this in!

And, lets get it fired up!

So, at this point, I decided to make the decision to go ALL OUT instead of just making another fast truck.

There are 3 things you need to go fast.
1. Less Weight
2. More Power
3. Traction to put down the power.

The engine was built to sustain 1000hp, so, power is not a issue at this point. So, lets start with #1. Less weight.

Removing the interior saved quite a bit of weight.

Also, I am aiming for a 10 second quarter mile. The procharger P1SC will not cut it. Sold.

So, a bit of work done on the interior, before wiring started.

Acquired a replacement for the P1sc.

Acquired a new intake and injectors.

And, had it all put togather.

Some fabrication has begun. Started with the dashboard.

29340320_10216188588526563_1451347252650967040_o.jpg


Painted dash, welded on a bracket to hold Holley EFI, and TCI TCU. Did a bit of wiring management. More to come.

Got it started up for the first time in years. Basic tuning done to get it to start and idle.


A day later, after a bit of tuning.


35F Cold start test.

April 17th. Building the exhaust

Started with an idea.
20180417_192948.jpg


Cut a few pieces to fit.
20180417_194826.jpg


And, started welding.

Downpipe finished, and wrapped.

Majority of the wiring done.

Temporary tablet mounted, for guages, and tuning.

Finished the cold side today.

Had to cut up, and re-weld a piece of 3" 16ga aluminum to fit properly.

Pieces cut, mocked up.

After welding (And grinding)

Mounted.

I also ran a few test hit, to ensure timing/fuel was where it should be.

On the both trips out, the cold side blew apart in differant places.

On the 2nd trip out, it also knocked off the main belt. So... I got to put my main belt back on, with nothing but a valve cover.

Made a few test hits, couldn't get any traction.


Found some better tires, had to dispose of the old ones.

Broke a ujoint burning off old tires.
20180525_145815.jpg


Put a new ujoint in. Made a pass the next day. Hit the throttle doing around 70.

20180527_161358.jpg


Driveshaft snapped in half. Reviewed the logs. Was only half throttle at 12lbs of boost

20180527_190840.jpg


Time to invest in a custom made driveshaft.

While I am in the process of funding and acquiring a new driveshaft, I am taking care of a few random issues I have noticed.

Tonight's project was to correct two spots on the cold side, which were blowing apart while under boost.

Spot 1, was the area in the middle. It would be kind of hard to get two pieces of flat, slippery aluminum to stay connected, especially since the ends were not flared.
20180528_193045.jpg


But, since I invested into a tig welder, not a huge issue.

Problem solved. Will never have to worry about that happening here again.
20180528_200027.jpg


Spot number two, was at the corner. Again, there was no flange.

20180528_200105.jpg


Again, tig welder to the rescue.

20180528_200742.jpg


Not a pretty flange, but, will give the clamp something to go against.

Tonight's project was to repair my broken alternator bracket.

One of the bolt holes was complelty busted.
20180530_193022.jpg


I had a spare sitting around, so, this was a 20 minute job.

The engine bay looks so much nicer without the extra bracket, alternator, and ps pump.

20180530_193031.jpg


Done.

I didn't take a picture of the finished project.

But, since I have a tig, I did want to attempt and repair the old part.

First, I put a bolt in, and starting filling all aroind it, careful to heat the aluminum and not the steel.

20180530_211014.jpg



After I had enough material, I grinded the excess down.

20180530_211550.jpg

Successful repair in my book. It threads, and it holds tight.

So, It is time to get a working gas pedal installed.

I did look at putting a factory drive by cable gas pedal on the truck... But, after stopping by a Junkyard, and realizing I would have to remove the steering shaft, and quite a bit of other stuff to remove the pedal assembly from the truck, I decided to take another route.

To note- The "Factory" dbc cable would have still required modifications.

Here is my factory, DBW throttle pedal.

1.jpg


I started by removing some of the extra metal.
2.jpg


And, I used a hammer to "encourage" the DBW sensor to go away.
3.jpg


At the Junkyard, I did pickup a random gas pedal from a random make/model of car. Ignore the piece of steel hanging off of my gas pedal. It was an idea which did not pan out.

4.jpg


I reassembled the factory DBW gas pedal, and used a piece of 16GA steel to fill in the hole left by the DBW sensor. I also re-positioned the stop slightly, to allow for more pedal travel.

5.jpg


I mounted the modified pedal back in the truck, to check for travel distance, and any other issues.

You will notice the hole, and throttle cable was already in the truck at this time. The cable came from a v6 Silverado.

The only modification required, was to drill a hole.

My next challenge, is to get an arm mounted, to actually engage the throttle cable.

6.1.jpg

I used a chop-saw, to remove pieces of the other gas pedal, which were not useful for this purpose. I then used a cutting torch, to work with the bends to allow this arm, to work with my gas pedal situation.

After that point, I ran out of daylight. I will finish up tonight.
