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:-)

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

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

Renault Etoile Filante (yes, a French car held the world speed record for turbine cars at one point - 190 mph in 1956!)

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...
