If you can build audio gear, building a car is easy. He's a shot of my baby moving under her own power for the first time. I still can't wipe this stupid grin off my face:

Very cool! Is there a Cobra skin waiting to go top, or will it always be nekkid like that?

wow - awesome - nice sound!

Sounds even better in person;-)
427 cubic inches of high compression testosterone!

427? I can't get a good enough look in the pix to ID the motor....Side-oiler?

Displacement is 427 but done on the 351 Windsor "style" block. Technically, this motor is called a 427w.
Bore is 4.125 x Stroke 4.00. Motor is a custom build on a 9.5 inch Dart aluminum block. Forged pistons and crank, snotty cam, and Brodix STS 225 heads, topped with a Holley 850cfm carb. When I get it broken in enough to put on the dyno, I'm expecting 500 to 525 ponies at the rear wheels. More than enough to propel a 2200 lbs car due to a very favorable power to weight ratio.
-
That is just awesome. Gonna need some very sticky tires, very sticky.
-
Amazing!
How hard is it to build one of these babies? Did you start with the full kit? I wonder how I'd get something like that registered in Mexico!
Please tell us more!!!
-
Nice work! It has a great sound too. I've heard a 427 Cobra and this sounds smoother.
I got a ride in a Supercharged S2000 today. It is only 350 Hp in a 2700 pound car. The stock car does 0-60 in 5.4 seconds. This is obviously faster.
-
Ken,
Sounds mighty impressive! Is the body modelled after something I might be familiar with? Something like a Chevron or original Shelby Cobra is coming to mind, but it's just a wild guess.
Are these typically built on some kind of donor chassis?
A very long time ago I was considering building a Sterling GT on a VW chassis and powering it with a 180 hp corvair engine, but life intervened and that never got further than acquiring the engine and tranny adaptor plate.
Hope you enjoy the new ride!

This is a Factory Five '65 Cobra Replica. There's several ways to build, but I chose the non-donor, "base" option. Basically received a powder coated chassis with a bunch of parts. I installed all tubular suspension parts, high performance brakes, independent rear suspension, hot motor and tweaked gearbox.
It's been a real hoot blasting around the neighborhood while correcting and adjusting things. Definetly overpowered, but fun!
To get it running I didn't spend alot of time or thought in wiring, just basically got it ran. Now that everything is working, I'm redoing very carefully so as to make it permanent (and pretty). Hope to get the car registered (legal) in time for Christmas, but will not get it painted until this Spring.
-
Ken,
Hah, so I guessed correctly on the
Cobra body. Very cool!
I'm sure it is a blast!
Have fun with it,
Jim

Hey Tickwomp; Great choice. Here's a story about friend Thomas Long's Shelby Race car that sold for $2.3 Million last year.
http://wheels.blogs.nytimes.com/2011/07/18/for-an-owner-of-a-shelby-cobra-a-bittersweet-return-on-investment/
He now owns a 1967 Ferrari 330GTC With V12 & 5 Speed Trans, completely restored and running the roads of Santa Barbara and beyond. I once drove a friend's Ferrari Rossa 6 cylinder between Ensenada(friend had inbibed too much) and Tijuana, before turning over the driver's seat to him, as the alcohol had worn off, and had only my learners permit at 17!
Love your car, but lust for something smaller and lighter, like a Lotus Eleven.
Cheers, Hank in Eugene

Cool story!

Yep, at first sight of the wheels, pipes and rear frame, it just screamed cobra.... HAVE to say, it is sitting in the top 3 of my all time favorite cars.... just an absolute stunning car with an amazing history.. if someone here isnt familiar with the inception and history of the shelby... they owe it to themselves to look it up and do some readin..... Carroll's original test driver was Teddy Teabags from jolly ol england... haha... wow, Lee Iacocca (Ford) literally gave Carroll a 'blank check' to develop a car that would beat Enzo at leMans.... Can you imagine how much fun that must have been for the Shelby team back then!! Just like rock and roll back then, things like that just do not happen today.... That kind of "free spiritedness" if you will..... I hope i am wrong, i hope that spirit is not lost.... I really dont think it is, it is just that accountants have taken alot of that "free spiritedness" hostage.....
-
And I am sure Paul enjoys the "blank check" that Doc gives him on each and every design idea.. ; 8)
-
Dang, I was hoping for a funny "quip" from Paul, but i guess he didnt bite...
-
Paul doesn't get a blank check. Dan holds him to a targeted price point. Otherwise Dan would sell only about 4 kits.
This is not to say that Paul doesn't enjoy the challenge of getting the best out of a given price point.
-

Lol! Its hard to get Paul to bite!
-
Oh, Doc and I go back and forth on who wants to trade what for better sound. Yeah, I still want to do an ultimate Paramount at $10K+, but remember Paramount started out as my way to make the cheapest possible 300B amp. It ended up in the middle.
-
Yes, of course all you guys are correct. and yep, the mark of a great designer is exactly what Doc and Paul are doing... get the BEST possible sound for a set amount... It just highlights how much fun it must have been for Carroll Shelby to have gotten the green light and blank check from Ford to build the fastest LeMans car they could...

I want to know if Ken is going to go with a dogged clutch? :-)

I went with a Quartermaster lightweigh racing clutch and aluminum flywheel.
Used a Super Alloy T5 customer transmission with 2.87:1 first gear, and a .80 fifth gear (basically a high performance close ratio box).
A lot of people simply use a Tremec TKO 500 or 600 (to safely handle the power), but they shift like cr@p. Normal Tremec T5 transmission can't hold serious power, but they can be rebuilt using hardened parts. If you're going to build a transmission, you can pick/match your gear ratios exactly like you want them. And finally, the SA T5 is one of the best shifting/feeling transmissions in the world.
The 2.87 first gear matches up well with my 3.55 rear gear and the .80 fifth means the motor won't fall on it's face between 4th and 5th.
As a bit of a project update.... I've pulled the front end apart to install power steering. Inititally, I thought I wanted manual steering, but I found it too slow and too heavy. Using a quick ratio Mustange GT rack and a modified Toyota MR2 electric power steering pump with aftermarket reservoir. Could have gone with a simple pulley driven PS pump, the electric can be mounted where I need to add weigh anyway (right front). Advantages of this setup is that it looks trick, puts weight were it's needed, power assist can be adjusted, and doesn't sap any power from the engine:-)

Electric power steering saps more power from the engine than just running a pump on a belt...through the alternator.
Going to have to disagree with you on that.
-
Please keep it friendly, folks. It's not worth getting into an argument over.

Watch it, the thread is going to be locked again.
I Googled "Electric power steering pump" and searched for specifications. The only one I found with a current rating had "Peak current 60A, Continuous current 12A." So it takes a peak of 60A to start it turning and 12A to keep it turning. For those who are not familiar with electric motor characteristics the peak current is "locked rotor" or dead standstill. Once it starts to turn it produces a Counter EMF that lowers the current enormously.
-
Yeah, I know. Disagree with anyone, and just have a healthy discussion...bam! Hammer comes down! There is a constant load on them generating pressure. When the steering wheel turns, current goes up. They don't draw only 12 amps. They are not more efficient than a pump on the engine. The pump is still doing the same amount of work, but if it's electric there are losses in the alternator, wiring, and the motor.
Okay, pick a number (how about 100 amps?) 100 amps @14v = 1400 watts. If 746 watts = 1 HP, then 1400 watts = 1.87 HP. No way a pulley driven pump pulls less than 2 ponies.
-
This brings up a question maybe both of you can answer for me.... It is probably a dumb one and you can hammer me all day long..., i love cars but not technically proficient.... I had before an aging car... it had power steering and was running like a POS... (it was running as bad as wax's quickie looks) hahaha joking Wax.... and when i would turn the steering wheel all the way,(lets say to the right), the engine would immediately bog down and the car would die..... Is that kind of what you guys are talking about? in other words something with my power steering pump had a direct effect on my weak running engine.... to me, i thought that the power steering mechanism must be putting a drain on the engines already struggling power??.... Am i a moron?...... Can both of you help answer? I have always wanted to know....
-

Actually I agree with your view on the subject at hand. Simply put it's about conservation of energy. But it's not the position you take that pisses people off, it's the petulant aspect of your posting style. Just leave the "why am I so much smarter than you?" attitude out of your posts and you will do OK. If you were smarter than me I wouldn't be having to tell you that.
-
hey all, maybe i'm outa line here but why is this gotten to be such a car oriented forum? and pubescent muscle car crap at that? how about lettin' this stuff go and getting back to tubes and speakers and such pubescent flea powered stuff as that there???? don
-
ok, now i'm wound up. here in long beach washington where i live every year about labor day an event is held that is called THE END OF THE WORLD ROD RUN. three days of geezers (i am 70) and their classic old rods. three days of sleeplessness for us locals. these arrested development types arping up their motors and paying $500 for the thrill of peeling out. and then these gd fools have the gall to resent the fines when we all know perfectly well that they would never think of doing that in their own neighborhoods...........we get eighty inches of rain per year here so on the years that the event experiences rain these morons cannot even move their heaps due to "environmental stress" give us all a break and put these things where the sun don't shine. any doubt about how i feel as to the question of muscle cars i am available to discuss (and cuss) this issue. 360 642 8853 don pettit

and please don't get me started on the pubescent activities of dirt bikes and gun shots. your neighbors do not wanna hear these idiotic antics!!!!!!! please be neighborly!!!! me, again

Wow! I just got caught up on this thread... No problems with 'low testosterone' here!

I'm not weighing in with an opinion, just a suggested reference.
I just read the Dec 2012 Car and Driver, pg. 54, article titled
'As car makers switch from hydraulic to electric steering assist in pursuit of mpg, are we losing touch?'
Quote-
'Makers are moving aggressively to EPS because eliminating an engine-driven hydraulic pump increases gas milage by about 1 mpg.'
Good article.
-
Consider me just an observer here. I DO enjoy all things physics, and so, this thread has interest for me. My only question here is about the 'general discussion' rule. It does say that we can talk about anything and everything in this area. Does that only apply to audio related subjects? I did not think so, but someone has raised the question before me, and I thought a clarification would help. Thanks in advance
-
It is indeed the general discussion area and is for off topic stuff as well as audio stuff that doesn't seem to fit into other categories. As long as tolerance and respect is shown by everyone any subject is fine. I do feel that politics, religion, and other incendiary topics are not really germane to this forum - and besides that there are several million other URLs where one can dwell upon those subjects.
Staying somewhat within the original topic here, I have been taking a few days off to decompress and one of the interesting subjects I have been reading about are the turbine cars that were developed in the 50's in Europe. To wit -
Fiat Turbina

cool pics! - amazing how far we have come!

Actually I was thinking how maybe we should a take a couple steps back, at least in terms of design aesthetic. For sure the turbines were noisy and terribly inefficient. But look up the drag coefficients of those cars...

i am totally chagrined. it has been pointed out that i have breached protocol. i humbly withdraw from these environs. i shall never darken these doors again. don

I saw a demonstration of the Chrysler Turbine at Lenox Square in Atlanta. It was said it would run on anything combustible, gas, "that good ol' mountain dew" (Moonshine, although a great waste to burn it) and the then popular Jade East.
The presenter poured in a bottle of Jade East and I ran to the exhaust, I could smell it coming out. He didn't pour in any moonshine.
I was most impressed with its lack of vibration. They put a quarter on the air cleaner and revved it up. It didn't even jiggle.

Don,
I was only asking for clarification about this site, nothing more. These fine gents/ladies here are good enough to accomidate all of us, as long as we don't 'get into it' with each other. No one here is asking for you to leave, and I, for one appreciate your contributions.
-
I appreciate the comments of those who are willing to look back at their posts and offer that they may have been able to word them a little more diplomatically. I have not threatened to ban anyone and I'm not asking anyone to leave. Yes, if any thread gets out of line I will lock it. And yes, if someone is being intolerant and can't make a point without belittling other posters, I will call you out. We all have a responsibility to look at how we word our posts with a thought toward how others will perceive it, not just how we intend it.
One of my responsibilities is to look at these threads as a future resource for others. If there is too much stress and strain in the conversation like has happened in this thread I usually make the determination that the static overwhelms the signal. Thus I am locking this thread in spite of the rather interesting initial discussion. Tickwomp, your project is just f***ing awesome.
