update Project scorpion II
Now here is a car that has literally taken years to complete, so when I give Danny Torres a badd time about not completely his cars, I should not be giving him a hard time because well, there is this car that I started around Christmas of 2005.. I started this car soon after I realized that show cars were not for me, when I was building this Speedster, I had visited Joe Horvath at Revmaster and asked him if he would sell me a 3 liter, I told him I was building a kit car and he said he was not interested at that time in supplying a motor for that car but if I wanted to go drag racing he would reconsider. I finished the speedster and had a lot of fun with it, the power was incredable but in actuality it just made me want more and I knew that if I was to do anything with the kind of power I was craving it should be done on a track. I purchased the body from Small Car Connection up in the desert, a 57 oval window that was used as a trampolin and also had seen some serious Baja action. The pan was not included in the sale nor anything else for that matter, just a semi rust free shell for me to diesect. This is going to be a really long article, so keep checking back cause there is no way I can do this piece in one sitting.
You have to look close, the top is really smashed in badd. Oh well that just means it needs to be chopped.Typical of me, I not affraid to call myself out. I though well as long as I have to replace the roof I might as well get it chopped, so I made a few calls and quickly learned that gettting a car chopped was very expensive and would take up to a year. I was having non of that so I got on the ol Intra Web and started researching “How to Chop a Bug” I found a step by step that looked fairly easy. Next thiing ya know I am at HomeDepot getting a carbide blade for my skillsaw. A couple days later I was done with my first chop. 4″ at the windshield.I think my wife hates body work more than me cause it makes a gnarly mess. The best part about that is that now when I chop a bug I do it completely different to avoid all the dust and bodywork. In the future I will do a chop article on here to show.All blasted up, alittle body work then I will get it sealed.I made a frame table in my garage and got to work, fitting the body on and off atleast a hundred time. Used all chromoly tube and tig welded everything to meet a 6.50 NHRA certification.I went with a different driveline setup in this car, if I ever break this it will not due to excessive power. Its a Currie 9 inch Ford.Getting the rear end all set up, typical four link like most back halfed V8 cars. Setup for Strange coilovers, etc etcTime to de Baja Bug it, I replaced the sheet metal rear apron and fender inners. At this time I made a rear wing out of aluminum that matches the contour below the grills, we luh them oval window grills and could not cover them up. Behind the car is a W decklid that I made to go under the wing, dont even trip cause when I got that decklid it had been run over by a truck, its a rescue item that if I wouldnt have saved it would be at the dump.Oh I study the history of drag racing, these Spindle Mount Cragar Super Tricks were the wheels of the 70′s and 80′s for Funny Car and ProStock, I powderd coated these black and yes they only cost me 60 bucks for the pair on Ebay.
On the rear I went with a standard CenterLine Convo Pro, 15 x 10″. While getting the car going we will use a 26 x 12 and eventually switch to a 28 or 29″ tall tire when more speed is needed.
Time to tackle the front end, I almost went with a fiberglass front end but opted for all steel body just for kicks. In this pic you can see a Liberty 5 speed shifter in the car, if the trans would have fit I would have used it, it was just too wide.Loads of body work, so if anyone ever ask why did I cut up a perfectly good oval, I will laugh. I saved a perfectly destroyed oval.
Finally loading it up for a trip to our buddy Earl Schieb for some color. While the body is being painted the chassis goes back to the Revmaster as Joe and I start maching the driveline parts to mate the Jerico 4 speed to the R3000 motor. This was the last time to the body was off the car. You can see that at this point most of the front end frame supports and motor plate mounts are not in the car yet.Here you can see the rear end set up, anti sway bar, panard bar, this car should launch very good and be stable. The 4 link bars are nickle plated. Another super funny tid bit, I spent so much time blocking out the car and skim coating it. It was soo straight, when I took it to Earl Shieb the hit the whole car with a DA Sander and ruined all the blocking I did. Of well its a race car right!Next we made a bellhousing, its made out of 1/4 dom tubing and 1/4″ plate. we tacked it together then checked it for alignment. After we finish welded it we decked it and machined the bore for the transmission to locate to. The bellhousing is pretty stout, NHRA gave it a thumbs up.All welded up and in the car, the clutch is a 6″ dual disk slipper clutch by DZE. The Jerico DR4 trans and the clutch will make this car super fun to drive, bang bang bang in the waterbox.Here is a shot of the clutch itself, it is pretty much a piece of art.I cant even begin to count how times the body was on and off the car, the motor plate and bellhousing are in but still no support bars in the front half of the chassis.
Finally time to start fitting the motor in, we did all the front half frame struts around a Big Block 180ci R3000 motor. The car will make its debut with a much smaller 153ci motor.In the early stages of this build were looking into running a Hard Anodized 4:71 blower from BDS. Also at this stage of the build you can see the sheet metal is being fitted and installed.It really looked sick with the blower on there.
Eventually we came to the conclusion that the 4:71 was just not going to give us what we wanted as far as boost. Man did it look good though.
In this pic you can see the belly pan is in the car, also the clutch fork and clutch linkage is being handled as well as the firewall being wrapped up.
Here is another pic of the drivers compartment after the belly pan was installed. We made a custom Tranmission top cover, its a helping hand.It only took a couple of times putting the trans in and out of the car to realize that a system was need to aid with servicing the clutch. The tranmission only weighs 60lbs but this little picker makes all the difference in the world. I should also note that we put the entire stock dash in the car, just becuase we can.Now we have the rear half of the car with all the sheet metal work done, brake lines finished and the wiring going in. You can slso see the battery which sits where the motor should be.All the rear suspension is wrapped up and ready to go. Moving to the back of the car the parachute sack is mounted as is the wheelie bars and a couple pages of todo items. If you are wondering why the we chose the paint scheme for the cars its because of this man, Sir Joesph Horvath. He served in the Marines and worked on fighter and trainer planes, the cars are painted like F4U Corsair war planes. If you ever get a chance to see our cars up close you will find that they show all the signs of being in battle but yet kept in fighting shape. Joe says the cars have hanger rash, even though the sedan has never been down a track it looks like it has been to hell and back and won its battles.Even though we expect this car to be absolutely stable we put a panic button on the steering wheel, if for some reason the short wheelbase car starts to get out of shape there is a big red button on the right side of the steering wheel that when pushed launches the parachute via a air cylinder.There’s the red button I was talking about, as far as gauges we have oil pressure, oil temp and brake pressure for staging the car.Here we are fabing up new oil and fuel tanks where the spare tire would be, the wireing harness is under way. The additional chassis supports for the strut towers are in place and the blower drive is fitted in the car.
Finally getting time to start making a motor, we started with a R3000 aluminum case to make the 90mm x 94mm engine. This car will run the new CNC 049™ Heads, Revmaster Barrells and soon The New Revmaster Forged Pistons. The compression is set at 10:1 and in this photo Weisco forged pistons are in it. The shaft sticking out of the front of the crank is what drives the ProCharger directly, no belts.Here are a couple pics of the heads as I was making them, first a semi hemi cut was done, then I started prepping the heads for dual spark plugs. With the exhaust gas temps we are expecting, we cnc’s the exhaust guides off in the exhaust ports to prevent them from burning off.
This is what the chambers look like roughed out, 44mm titanium intake with a 40mm titanium exhaust, dual plug. There is still a lot of work to be done on the chambers as far as blending and unshrouding around the valve heads.Here is a trick Revmaster has been doing to there turbo airplane engines since the early 70′s, a thickwall tube is pressed into a bored hole where the head stud pass’s thru the finned area of the head to eliminate the head from flexing under high cylinder pressure. The tube then acts like a solid mass of aluminum between the rocker box and the mass surrounding the chamber. You have to look to notice the thickwall pipe.
With the heads comming along we started began doing all the clearencing needed to fit the 90mm crank in the case. I think we should skip all the motor stuff for now, this post is already pretty long and the motor prepping could be a post in its self. So one last motor prep picture, the 6″ rods are chamfered to clear the cam better, we also fit these rods with ARP2000 3/8″ bolts, the good stuff.Again its late and time for bed, I will continue tomorrow.
