About my GTO

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.

Cooling Pulled the trigger on a Moroso Remote Electric Water Pump with all the fittings to eliminate the LS1 style water pump. Expect the shipment to be in sometime next week. We are also going to move the AWIC reservoir to the rear of the car, putting it in the trunk.

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 an AWIC reservoir with a front mounted heat exchanger.

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. That Supercharger is a beast. We have seen 19 lbs of boost on the engine thus far with the OEM pulleys. We also replaced the 2004 GTO radiator with a 2005 Radiator to eliminate the large fender mounted catch can.

Fueling. For fuel we went with 83 lbs Accutron Injectors fed by an Aeromotive A1000 pump through a -10 an line. The -10 splits into 2 -8 an lines into the rails with an Aeromotive Regulator sitting on the other side maintaining constant pressure. We used the OEM fuel system to complete the return.

Clutch/Tranny. One of the reasons we built the car was to stress prototype Monster Clutches. Monster Clutch and SNL Performance have done all of the fabrication on the car. The T56 was built to go to 1000 ft lbs of torque using carbon fiber synchros, brass shift fork pads, steel shifting forks and face plated components. The current clutch is a Monster 11" Ceramic that went straight from the rack to a WOT pull on the dyno. That clutch has held for over 3,000 miles now. See a couple of Dyno pulls below.

Drivetrain. We turned our attention to the drivetrain with a complete drivetrain by GForce1320 including the 3.5 inch carbon fiber driveshaft, 8 inch tubs, coil over kit, 33 spline stubs and hubs, 300 mm CVS shafts, and a 33 spline spool using 3.46 gears. 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 modified the GTO Shifter by adding a GMM Race Unit with an SNL developed Hurst shift lever adapter. Currently we are still trying to figure out how to get a hood on the car.

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.

Measuring and masking it off, had removed some of the sub bracing Friday. Initial cuts are well inside what we expected the ultimate dimensions were. Kept the cuts small and closed the hood frequently to judge measurements. Undecided about covering or leaving out in the open until we saw what we had to work with when we got it to close. I will be looking to see what it would take to cover the blower and intake. Next major hurdle was the intake and Throttlebody. Inexperienced worker was a barrier, a few unnecessary dings and scratches And here is the hood closed, next stop body shop.

Okie the Whipple is 100% so we are going to start trying to get all the parts working together. Here is a shakedown romp through the gears.

Trunk didn't have enough in it so we added more. I didn't want anyone to be scared so we went for the stealth look.

Began mocking up the fan today. Belt and tensioner are in and installed. Its a matter of hooking up the fan, plumbing the cooling system, hooking the evac system up and the crankcase ventilation.

Pretty good day today. Bruce finished the trunk and back side wiring then moved to the forward engine compartment. He completed most of the cable wiring from front to back as well. In the engine compartment he linked everything to the distribution box and fed from there to relays for the accessories (as you suggested), fans, pumps, etc.

I am looking for an electric twin fan with a very low profile, preferrably less than 2.5". Without that we may have to modify the radiator mount and or build a new radiator. Any ideas would be appreciated.

We had to weld tabs on the bottom of the valve covers to prevent them from slipping off under pressure. Other than that they bolted right up after fabricating them to fit beneath the vacum on the driver's side

Fabulous day today. Got the bulk of the remote water pump fittings mounted. All that is left now is to resolve the heater issue and string the hose. I think the pump mount was pretty cool, drilled a hole in the frame and fed the -12AN swivel fitting through the frame. This way if the wheels somehow get up and we bounce hard, the water pump will have a backup brace to hold it and keep the unit out of the belts and hoses.

Got some more welding done today for the Power Steering Reservoir and the drivers side valve cover which needed to be notched. Should finish the valve covers by Saturday. Hope to finish the battery mount saturday and the hose installations by next Wednesday. With that done the machinist is moving forward on the final tension pulley bracket. Actually can envision getting her on the dyno soon.

Got a little more done today. Began to test fit the -12AN fittings with the remote water pump. Have one issue I will heave to solve with the driver's side lower fitting. Solution may be to reroute the belt, the 90 degree -12AN swivel fittlng hits the belt on the traditional tension pully mount. Still waiting on 4 -12AN Fittings from Jegs. Also got the plugs for the back of the remote thermostat and the temperature sending unit opening.









One of the biggest projects was to weld the heat exchanger coolant reservoir to the XS Power battery tray. I think it looks pretty good and gives me a place to mount the tank flat and secure in the trunk.SNL is working with a new fabricator who does an excellent job.

Pulled the trigger on a complete Moroso Electric Remote Water Pump with all the fittings today. Saw the SEMA display and an actual electric mounted on a BBC last Saturday night, in lust with the look. Hopefully we will get the shipment from Moroso this week and start laying out the install. We have one spacer still being fabricated for the tensioner pulley.

Really happy with SNL visit today. Things moving forward. The upper cog drive and shaft are fabricated and ready to go. We have the tensioner and need to resolve mounting it. Right now waiting on belt and a couple of spacers. The best news is once everything is lined up we may not need to change the radiator.
