Project Tomahawk FTI's 2004 Pontiac GTO Buildup Phase I Phase II | Phase III |
We started the day at Mike Dez Racing in Seekonk Massachusetts (508-336-6588) so we can gather a baseline on the GTO's horsepower levels. Mike and Brian cinched down the bright yellow “goat” for a few tests and the party began. Power looked good for a new engine and after four passes the HP really didn't vary all that much. Peak horsepower levels were running around 286-289 RWHP so the stock flywheel horsepower rating of 350 is not far off! I'll try to get the files from Dez Racing and load them up later. After some “what ifs” as to the car's potential, we had some Cokes and pizza as we checked out the dyno sheets. The guys noticed a few items from the “Goat's” dyno graph that needed attention and once I have HP-Tuners in my greedy little hands, we'll have those problems rectified. | |
Around 2:00 pm I left Dez's joint and headed north on Rt. 95 towards New England Dragway in Epping, New Hampshire. There were a few traffic problems on the highway because of the holiday but the new toy ran flawlessly all the way there. What a great ride it was! The CD player blasting out the typical early Van Halen and older re-mastered Grand Funk Railroad that I love to hear. Fitting music for the old and the new venue of this GTO project car. I finally got to enjoy the car for more than just a short trip around town for a cruise night or just a craving for some speed...It was the best. When I arrived at the gates of NED, I was rewarded with about a one-hour “hang around” time just waiting for the track to open up. At least it allowed the “goat” a well-deserved cool down period for its brand new engine and drivetrain. Once in the gate, I breezed through Tech and drove right up to the lanes. There we waited again for almost an hour for the track personnel to get the facility race-ready. Guess I should have figured this all out since I've always known the NED routine was not the most “racer friendly” but at least it gave me time to cool the engine down even further and spend some time answering a few questions about the new “goat”. At 6 pm the lanes were officially opened and I was finally strapped in heading up to the starting line. I did a slight burn out to clean off any pebbles, then push the button to shut off the traction control and dropped the "Goat's" shifter in “3”. A couple of seconds of gauge checking and it's up to the beams. I shallow staged to minimize the ET and brought the revs up to 1000 with the foot brake on, holding it on the line. The tree dropped and I was off with a howling of the rear tires. | |
The scoreboard showed a reaction time of .465 RED but hey, it's my first time down the track with this car so cut me a little slack.
The brand new LS1 engine sounded really sweet at the top of each gear change and both were consistent at 6000 rpm per the stock tachometer. I looked up as I passed through the lights and saw a first actual ET of the car. As I approached the time slip booth, at least I knew it wasn't a fifteen second pass. | Run #1 R/T: .465 60' 2.172 330' 5.985 660' 9.085 MPH 79.58 1000' 11.775 ¼ 14.049 MPH 99.19 |
I hot lapped the car back to the lanes to see what I could do if I tried something different at the start.
Other than getting used to the dynamics of this car, all I did was show that a hot engine does not like to be raced. | Run #2 R/T: .530 60' 2.141 330' 5.986 660' 9.085 MPH 78.76 1000' 11.828 ¼ 14.118 MPH 98.56 |
I upped the tire pressure in front to 45 psi and reset the rears at 35 psi. Just to see if this would help anything! Jumped back in and got I line.
Much to my surprise the lanes were moving quite quickly and again with little to no cool down, the car went its worst pass of the night. | Run #3 R/T: .524 60' 2.156 330' 6.029 660' 9.189 MPH 77.98 1000' 11.928 ¼ 14.242 MPH 97.43 |
This time I allowed the engine to cool down about a hour or so before returning to the staging lanes for another pass. I had been running the left lane for a true back-to-back test but this time I wanted to try the right lane at least once, since the left was not hooking at all with the stock tires. I also babied the car a bit more, leaving as if I was sitting next to a cop. The car seemed to like this approach as the elapsed time returned to the 14.0x time I had run the first pass. So close to a thirteen but I knew I needed more “bite” to get this car quicker. | Run #4 R/T: .732 60' 2.107 330' 5.939 660' 9.052 MPH 79.09 1000' 11.752 ¼ 14.027 MPH 99.19 |
This was going to be the last pass of the evening for me so I had to think carefully about my next move. I wanted that high thirteen and possibly a 100 mph pass. I was tired and had to look forward to a two and a half hour ride back home so I tried something a little odd as a final effort. I feathered the car out of the hole a little more before I planted the throttle. Helped a little but… | Run #5 R/T: .734 60' 2.125 330' 5.944 660' 9.048 MPH 79.25 1000' 11.736 ¼ 14.005 MPH 99.50 |
Oh well. The baseline is there so we'll see what a set of drag radials and a homemade inlet pipe will do. |
