Ethyl Roars

Ethyl is a 2004 GTO I bought her new in November 2004. We put 95,000 miles on her with 80,000 of them being at 450+ rwhp. In May 09 we decided to go completely through it. First off the original LS1 running heads and cam for 85,000 miles only required honing, cam bearings, and rings and is back in another GTO making nearly 500 rwhp with forged internals, heads, and cam. In our build we initially started to put a 91 mm Borg Warner Turbo on but switched to a PD twin Helix Harrop HVT2300 supercharger. After getting it together we decided to go with the 4.0 Liter Whipple to see how far we could take the Texas Speed and Power built 408 LQ9 Engine.



The engine. We started with a LQ9 Iron Block built by Texas Speed. It has Diamond Pistons, Eagle Rods, and an Eagle Forged Crank. The entire rotating assembly is coated and the pistons are a -28cc dish. We put ETP 245 heads on the car and retained the 1 7/8 inch Kooks Headers.



Fabrication. We relocated the ECM to inside the drivers compartment and fabricated a coil pack relocation scheme with some modified GM Performance Valve Covers to clean up the appearance. We fabricated a reservoir with a front mounted heat exchanger. We fabricated the intake for the supercharger and the brace for the snout pulley,





Forced Induction. We started out intending to put a Borg Warner 91 mm Turbo on it but went with a Harrop HVT2300. Our goal was 20 lbs of boost since the engine was built to go to 1500 HP. The Harrop maxed out around 18 lbs so we went with the Whipple Sand Rail 4.0 Liter Supercharger Kit. That Supercharger is a beast. We have seen 19 lbs of boost on the engine on the Serpentine belts with the OEM pulleys. We also replaced the 2004 GTO radiator with a 2005 Radiator to eliminate the large fender mounted catch can.



Cooling Includes an 05 GTO radiator and a Moroso remote mounted electric water pump. We used an aftermarket heat exchanger off a Cobra and a Moroso Heat Exchanger Reservoir which is trunk Mounted. We wired three fans behind the heat exchanger to pull air through them. A Flex-Cool low profile fan completed the setup.



Cog Drive. The Serpentine belts could not hold so we added a custom foabricated cog drive using Procharger and some custom designed and fabricated parts. We had to work through a serise of issues including the snout not holding up to the demands. We designed and fabricated a unique cradle for the snout and top sprocket. Once we were with the cog drive it became apparent the 80 lbs Siemns injectors could not keep up. Also the IAT's were high and the car did not respond well to meth. We installed Bosch/ID 2000 cc injectors and converted the car to E85. We've been able to consistently hold the car at 23 lbs of boost though the Aeromotive A1000 is max'd out. The current setup is a fuill return system using a combination of Aeromotive and custom fabricated parts.



Transmission. We could not get a T56 to stay together so we had RPM transmissions build a T56 Magnum with a GForce 9310 dog cut gear set, micropolished by Liberty Gears. The setup was awesome and scheduled be installed with a Monster Triple Disk clutch. Unfortunately the Transmission took so long to deliver we had already gone to FTI for a Stage 5 TH400 by the time it arrived. Reluctantly we dissassembled the T56 Magnum and sold the parts for scrap. We have the TH400 in now.





Drivetrain. We overpowered the OEM drivetrain so We turned our attention to GForce1320's 9 inch Ford IRS. We are using a Wavetrac 35 spline differential with 200 mm GForce axles. The car has tubs, and a GForce1320 coil over kit, We will be running 14.5 inch slicks on 15 by 10 Holeshot Rims with 15 by 4 inch skinnies on the front. Currently have MT ET DRs, 295 by 55 by 15s on it.



Finishing touches. SNL put a Kook's afterburner 3" exhaust on the car. We added a FireCharger fire suppression system and Prosport AFR/Boost gauges. We've installed an RPM Rollbar and B&M Quicksilver Shifter. We also installed a 100 shot on top of everything as it seems to help IAT's a bit. We have a shop standing by to do the hood when we get everything else finished.

Suspension. Lovell's suspension components from Kollar Racing will replace every component in the suspension with new bushings, and fittings. We are also going to the Lovell's 90/10 struts as the car will work mostly on the strip once completed. We still need to complete the hood, add the Roll Cage, and completely repaint the body to finish the build.

Back to the fifties in Minneapolis St. Paul. It is held every June by the Minnesota Street Rod Association. Was a huge show.
Re Plumbed the fuel filler line, added a vent to the tank. Took her out to blow the dust off of her

Kind of trying something new. Recently built a solo guitar kit. Didn’t turn out badly. I use it as a road guitar now. The shop where most of my work is done does some awesome vehicles. Recently they have been building a Studebaker Truck. I am in love with it and thought a guitar that matched it would look awesome.

Went to Texas Thaw in Wichita Falls Texas yesterday. Some pretty cool Gasser action. First video is a timeworn Walk through which some of you might not enjoy. Video 2 and 3 are taken during the Drag Racing, and there is another with all the cars at the car show plus a cool wheelie clip. Enjoy

Highlights and still shots

More Guitar/Hotrod Porn. Finishing two Guitars for friends cars. The studebaker is almost done and the latest one for the 55 Chevy wagon is coming along

My cousin had a beautiful wedding and they used my Hot Rod as the getaway from the reception. Kind of brought a tear to my eyes to see how much they enjoyed it.

A few miles on my Hot Rod so went through the Steering Components. Replaced the original gear with a complete Borgeson suite from the rack input shaft to the steering wheel. Took a little figuring, some grinding and sanding drilling, and of course locktite. Several advantages over my OEM Factory five equipment include a slip shaft to compensate for forward and backward pressures caused by the rack being stationary (bolted to) with the frame. Borgenson has a 40 degree UJoint not advertised in their catalog I used to connect the outer firewall shaft to the rest of the assembly. This joint is very beefy and seems to operate much more smoothly than the original 30 degree joint. The input shaft is problematic as in the past, pressure from the different flexing of the assembly compared to the frame resulted in a tendency to pull the UJoint off the input shaft, Next problem was the boots on the tie rod ends were worn out and literally falling apart. With no real guidance as to replacement part numbers and it being late on the weekend when I started, I discovered Flaming River boots/bellows to fit the rack. After replacing the entire steering assembly and the boots, we aligned the front. results are rewarding, car tracks straight, feels steadier, and has no lag in the steering assembly.

One thing that has bugged me for some time is the appearance of the glass in the fitment to the windshield. This weekend went out and bought some cheap rubber chrome stripping and detailed the edges of the windshield. Could have done a better job on the corners but overall for $20 and a couple of hours of thinking it through I thought it turned out well.

Hi Bill, I like the look of the chrome trim on your window. Good job. I was wondering what the part number for the 40 degree u joint was. My lower steering u joint works but it is really tight at full turn. This would be a good problem solver.

You have to ask Borgeson for it, they don’t advertise it, call their tech and ask for either Jeff or Dan. The joint is massive compared to the typical joints. You’ll have to be careful of the geometry after the install, look for binding. One thing I did not save the receipt on, go figure.
