4-12-04 Single Thumper Project

I will start off with what I had and why I am changing. What I had was a Paxton Novi 2000 on my stock blocked 347. Here is a list of the mods on the car. This will surly cut down on the amount of questions I am asked later.

Comp Cams 1.6:1 Pro Magnum roller rockers.
Isky valve spring w/ titanium retainers and locks.
Canton Racing Pro oil pan w/ tray and scraper.
TFS 'R' intake w/ 1' spacer.
Accufab 75mm throttle body.
Compression is at 8.6:1 and the displacement is 347c.i. Redline is 7200 rpm.

Drivetrain:
Tremec 3550HD 5-speed transmission. (Swapping soon)
Steeda Tri-Ax shifter.
McLeod SFI bell housing.
Billet steel flywheel and Centerforce Dual-Friction clutch. (swapping soon)

Paxton .5' fuel rails.
MSD 96lb/hr injectors.
Aeromotive adj. Fuel pressure regulator.
AEM C2DI ignition amp.
Taylor .409' custom-built spark plug wires.
Factory distributor.

Power Adder:
Garrett UTV9406 turbo charger.
91mm inducer, 142mm exducer. 1.0 A/R hot housing.
Mental Addiction Motorsports extruded intercooler, 26Wx14Hx4D.
Twin Tial 38mm wastegates.

Engine Tuning:
AEM EMS (Engine Management System) stand alone ECU.
AEM dual channel wide band O2 sensor controller.
EMS internal data logging system.
Autometer gauges and shift light.

There was nothing wrong with the blower but the fact that I could not turn the power down was a little disappointing. The car made 11psi with the factory pulleys and made over 500rwhp. The blower was also loud. Not the head unit itself but the BOV (bypass) and exhaust was a little overwhelming at times. I did what I could to quite the car down without sacrificing too much power. The main reason for the switch was gasoline. The blowers Air Intake Temps were just too high to run on pump gas. A lot of it had to do with spinning the engine up to 7000rpm too. When I turned the boost up it was so hot that the car rattled on 100 unless the A/F Rs were below 11.2:1. Pretty fat. The Novi 2000 is also only worth around 1000hp to my engine. I wanted a little more.

The goal is to make 1000rwhp and to do it on a relatively low octane gas. 100LL would be perfect but some 112 mixed in for some kick would be livable. This car is a full weight street car. HVAC (including AC), power steering, ABS, hydraulic roller, cruise, stereo, and power everything have all been retained. The car will also be used for Auto-X, road racing (for some weekend entertainment), and for trips to Las Vegas and Cali. For those reasons I have decided to use two Tial 38mm wastegates for regulating the boost. I know I can probably use one Indy-gate or one HKS race-gate but I am on a budget and I think the twin gates will look cool next to the turbo. To get the car controllable I need to get the power down to around 400hp. After countless hours of thought about what to use and where to put it a plan was formulated.

It started out that I was going to utilize Garrett's new GT technology. After a few months of research and dead ends it turns out that the GT wheel that I need is not going to be released any time soon. I was looking for a mid-frame turbo that would support 1400 peak hp. Knowing that I would have limited space to work with it seemed the only logical choice. Working with John at Limit Engineering he decided that it was not possible to get my hand on such a beast. He did some research of his own and came up with the UTV9406. It's a Garrett turbo. I have no idea what it goes on. My guess would be an off-road machine or a generator. The turbo in question is an experiment. We have no idea what to expect. On the bright side of things, the kit will be designed around this turbo and it has the same dimensions as a Thumper.

The Dart block just arrived and the radiator, turbo, wastegates, and k-member should be arriving with in the next two weeks. The motor should be done and ready for install by next weekend. It is then that I will be starting the documentary. I will start with the turbo placement and how to start the header. Using steel plate to hold flanges in place and techniques I have learned over the years of watching and building custom performance parts.

It will be a long process with lots of long nights. I will post as many pics as I can through out the process. I know a picture is worth a thousand words.
