The Allison......

You used to be able to buy these cheap (military surplus), so they got stuck in everything...

And if one was good, then 4 is better, right ?

And the Infamous Novi V8 Indy engine. 

Run from early '40s, to 1965, and along the way killed several drivers due to the peaky power band.

Many later drivers refused to drive a car with this engine, as the boost from the Paxton blower would come on hard at high rpm, and break the tires loose.

#1535108 1974 620 Ultra Quiet Exhaust: Adapt 720? or?

Posted by G-Duax on Yesterday, 08:20 AM

Add a good thick layer of sound deadening, like DynaMat, to underside, doors, back of cab, and under the whole bed.

These trucks were not made to be as quiet as a Lexus while driving.

All that tin amplifies any noise made by the engine.

 

Either that, or remove the dirty, noisy internal combustion engine, and replace it with a Green Planet electric motor, then fill the bed with 1000 lbs of batteries.

And then there was the 1931 Duray 16 cylinder supercharged 2-stroke Indy car.

Know to be the loudest car ever to run the brick yard.

Was a total failure....

1950 #61 Indy car with Cummins sponsorship, and diesel engine:

They returned in '52, and took pole with this:

Unfortunately, turbocharging was in it's early years, and the one on this car failed due to tire rubber clogging the compressor inlet.




#1534381 Best coil-over option for '76 620

Posted by G-Duax on 12 December 2017 - 01:30 PM

Why don't you think an S13 R200 diff won't take a measly 500 hp ?

I know of many 700+ cars with that size diff in them, and they don't break.

 

Just don't use one with the Viscous diff, they don't work for anything....Good idea, that just never worked right from day one.

They barely hold 150 hp when they are at the right temp.

Too cold, they don't hold, and too hot they don't hold.

 

And all you have to do to put 1000 hp through one is to install an S15 helical, as it has the larger 30 spline output shafts.

Plus it being a helical, there is nothing else out there as good for road racing.

 

The IRS is worlds above in handling over any solid axle set-up.




#1533903 Coil over conversion

Posted by G-Duax on 09 December 2017 - 12:51 PM

I've seen a 510 diff & sub-frame put under one.

But why ?

Weaker diff, which probably goes for the Miata one also.

 

Would be easier to turn a 240 into a pick-up.




#1533511 Electric cooling fans - Two pullers or One pusher?

Posted by G-Duax on 07 December 2017 - 09:46 AM

Yup.




#1533372 Alternator wiring

Posted by G-Duax on 06 December 2017 - 04:02 PM

Or just use a 1-wire alternator...

 

PM06-300x200.jpg

 

But, on an all out race car, I still use an internal, but then I use a full throttle switch to cut the field coils,

so that under full throttle, the drag from the alternator goes almost to zero. (belt & bearing drag still there)

 

On a little 4-cylinder, 6-8 hp means a lot.




#1532927 Electric cooling fans - Two pullers or One pusher?

Posted by G-Duax on 04 December 2017 - 02:02 PM

A stand alone ECU is kind of out of the question for many Datsun owners.

I run a separate 30a relay for each of my fans on the 620, and 80 amp relays on my Cressida.

Never a problem....

When using a fancy, multi-function fan controller, I always just use them just to turn on & off secondary relays.

Very little amp draw to turn on another relay, and if something fails, and over loads the system, such as a fan failure, the secondary relay takes the abuse.

The controller never takes the death blow.
