And  I am sure  Paul enjoys the "blank check" that  Doc gives him on each and every design idea..  ; 8)

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.

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? :-)

-- Jim



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.
