AZB755V8 Posted June 26, 2018 Share Posted June 26, 2018 Dirty old hood just sitting around needing a cleaning bad. Waiting for temp to cool down in a month or so, to get out and blow a little smoke, about 110* today. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/53525-dirty-hoods/page/2/#findComment-401371 Share on other sites More sharing options...

The Superliner still has the custom aluminum and stainless locker on it. I got sidetracked for a few years, on my Cobra project. Think I need it more than a bunk, not ready to lay down a lot just yet. This is the Cobra, Yes that is an all aluminum 860 cu/in V-12 that was used in a boat. Stock 1150hp /1200ft/lbs and gets 3.5MPG just driving normal!! It is detuned to actually drive it on the street. Those tires are vintage correct but are no longer on it and 13" wide road race tires are used for traction. 3 Quote Link to comment https://www.bigmacktrucks.com/topic/53525-dirty-hoods/page/2/#findComment-401438 Share on other sites More sharing options...

This was a sled puller from Wisconsin back about ten years ago known as Thunderdog. The modes were done by Steve Trevetz the V8 Mack Engineer and the inline pump and injector work was at Antrum Diesel. Was wheel Dyno'd in Wisconsin once all together. Dyno quit reading at 1158hp with more to go. Ya, 1200hp was an understatement. I have a smaller turbo, still makes 65psi but at lower RPM's, on it now as it just would not pull a trailer and always "under the turbo" at cruise speed. The silver box in the top right corner is an added Liquid to air inter-cooler, after the air to air, that really helps for short periods. Flows 1.25 gallons a second of ice water for about 15 seconds then ice is gone in a 20 gallon tank in back locker. It does need a huge clutch and Rockwell lockers to hook-up!! It is a 93-94 Black CL700 motor with the factory chrome valve covers. 3 Quote Link to comment https://www.bigmacktrucks.com/topic/53525-dirty-hoods/page/2/#findComment-401440 Share on other sites More sharing options...

j hancock Posted June 28, 2018 Author Share Posted June 28, 2018 For years Rolls-Royce would say the HP rating for their vehicles was "adequate". The HP rating on your Cobra must be "Adequate Plus"!

HP Rated "Just About Enough" and detuned at that, down to about 1000HP at the crank. There are but VERY few places to crack it open due to street conditions, like the boys in blue, without drawing BIG attention. I got a CDL to worry about too. License Plate reads "Venomis" Misspelled but we only have 7 digits to work with in AZ. Funny but no one can USE that kind of HP in the car or truck that was 1000HP at crank or to the wheels. BUT it is nice to know that it is there if ever needed.... 👍 Edited June 28, 2018 by AZB755V8 1 Quote Link to comment https://www.bigmacktrucks.com/topic/53525-dirty-hoods/page/2/#findComment-401462 Share on other sites More sharing options...

ERA FE 427 SO with Toploader and Jag rear. A hell of a ride and I am glad she is gone. No damp roads here but oil at intersections is a big issue. If it rains it is like ice starting and STOPPING. Yes, a Cobra can get out of hand in a split second, that is what makes them fun and a hand full in any configuration. Not for the faint of heart to be behind the wheel. Have had people (women) screaming from first gear on and getting out with a smile on their faces and shaking, no wet seat yet but said close! That was after having them strapped in with a racing harness. This all under 75MPH and in third gear of course.

h67st Posted June 28, 2018 Share Posted June 28, 2018 AZB, is the Cobra body fiberglass? Is it chrome? It sure looks like it. Quote Link to comment https://www.bigmacktrucks.com/topic/53525-dirty-hoods/page/2/#findComment-401481 Share on other sites More sharing options...

The Cobra body is polished aluminum with brushed strips. Same material as the original ones built in the 60's. Kirkham Motorsports in Utah has the bodies and frames roughed built in Poland. They then finish the rest here in the USA the customer has to supply the engine. Copper and Bronze bodies are options but way more money and 400lbs plus heavier. This car is a little over weight with that engine at 2600lbs. Fuel adds 270 more plus me. It ends up about 3lbs per HP for power to weight ratio.

BillyT Posted July 5, 2018 Share Posted July 5, 2018 The LTL is a piece of art! Haven't seen one of those turn signals with the arrows and the little visors in 60 yrs! Let alone chromed! Speaking of "Off the wall tranny combos" I used to know a guy with a F 350 hotshot tractor that he swapped in a 5.9 Cummins with a ten speed road ranger! First time I've ever seen a Ford pickup with a ten speed "ranger" he had a little electric air compressor to run the range selector! 2 Quote Link to comment https://www.bigmacktrucks.com/topic/53525-dirty-hoods/page/2/#findComment-401972 Share on other sites More sharing options...
