60's style Gasser Willys build

[chevy2]

Using a spool in this type of car is pretty standard fare and in preference to an lsd,
running something like power levels of 800+ horsepower and similar torque levels through a transbraked transmission (basically dropping the clutch at full revs but with an auto) and through 12" or wider slicks designed to dead hook,
The result is often wheelstands and first 60' of track in around 1.3 seconds,
an lsd often wont handle these torque levels which in turn breaks one wheel loose and the result is rear wheel steering often putting the car into the wall,

Its not a cheapskate thing but a safety item,

perfectly usable on the street,
As this car owned by a friend below demonstrates,
1000hp, has covered thousands of street driven miles over the last 10 years including a 1600 mile round trip to Sweden last year,

This car was no expense spared build designed for street use with.....a spool.

Nah I'm to much of a cheapskate !!!

Had a stroke of luck on sunday I thought I was gonna have to make a grooving tool for the alternator pulley but chatting with my mate Brian and he said he had a grooving tool for vee belts, so had a borrow of it today and put the groove in the aluminium pulley I made up earlier

interesting stuff, sort of similar to the custom bike scene where quite a number of bikes are hardtails (no rear suspension), open belt drive primaries and so on, lots of supposition that they are not ridden any distance, but quite a few are and not trailered to rallies,you just deal with the idiosyncracies of the build and what the road throws up at you.
Really enjoyed working my way through this thread- inspiring stuff.

if the car has done many miles on the road i wouldnt imagine the engine would fare well with an open air intake without a filter eg rain dust and crap of the road

Reminds me about my first motorbike. I removed the air filter housing and put part of a pair of tights held on with elastic bands over the carb to act as a temp air filter. First time I reved the bike it sucked the tights into the engine

There are many that are hidden, There's a local guy I know called Sandy who builds wild raked out, hardtail, open primary, low rider customs, he rides them to every bike rally he goes to, distance doesn't stop him either.

I also know a local bike shop built a hardtail pan head with a kicker box and it took at least four of them to start it. . Another guy I know started it on the four kick.

Unfortunately that pic appears to show an open scoop but theres actually two air filters in there,
No filters and heavy mileage will certainly shorten engine life.

If you zoom in you can see the front filter

No filters and one stray stone/nut/bolt/small pigeon will drastically shorten engine life!
It always makes me cringe when I see open trumpets etc on track/race cars.

Well the Willys is tucked up in its lockup but still been making bits that have forgot, was topping up with coolant and realised I had no catch can fitted

I know I could use a coke or beer tin like some people use but wanted something a little better, legally it has to hold a pint but I made it hold 1.5 pints.

Was going to make it in stainless but as I don't really weld much aluminium I thought it would be good practise

Had a look in my scrap ally bin and only thing suitable was a piece of 5" diameter x 1/4" wall tube, A bit big really so I decided to turn it down in the lathe to .050" wall thickness.








Once the turning was done I slit the tube down the side and used a piston ring compressor to pull it down to 3.5" diameter.










Next job was to make some end caps, I didn't want flat ends so I metal spun some .050" flat aluminium sheet in the lathe to make curved tops, this is done by spinning the lathe at its fastest speed and pressing against the aluminium with a piece of hardwood dipped in tallow, Its gets very hot through friction, crude but it works
Once made the caps were welded in place, wasn't worried about the weld as it was to be scurfed off and radiused. I had a bit of a problem welding the .050" as I really needed 1.6mm tig rods but all i had was 2.4mm rods, the 2.4 rods tend to cool the weld pool too much and also give a higher and not so neat bead.








Next I spun up some threaded bungs for the top inlet and the bottom drain, also 2 more for the sight tube, these were welded in place, welding getting better with practise










I thought I would give it a polish










After spending time polishing it I realised I didn't actually like it polished so scuffed it up and painted it satin black, looks better know !!!
I also welded on a mounting plate but forgot to take a pic

Is the black paint a bit of psychology to make the competition think it's heavy old steel?

Hahaha, no mate, it's just the polished version stuck out visually on the black chassis and I wanted it to blend in plus my vacuum tank is on the opposite side and is black.

Some lovely touches.. I particularly like dishing the ends.. so many of the catch tanks and swirlpots I see in vehicles are just a flat plate, I appreciate for them its purely cost influenced but to see subtle things like that are so nice..

the conical shaping on the threaded bosses too for example.. details!! Its all in the details...

love it...

Thank you mate.

Managed to get the catch can mount made today in between nipping round to my mate Jason to help him progress with Wiggys T bucket, again its made in aluminium and bolts to the chassis with 3 x 1/4" unf bolts, just need to paint it black and bolt on.
Also got the bottom of my aluminium welding problems, turned out the AC cleaning dial was wired backwards on my welder so when i was selecting penetration i was actually using more cleaning !!! Had be going till my mate came over and worked it out.

hello , any more progress it's been awhile since I've had a look , been having a break ?

Sorry dickie but I don't come here very often these days, Yup its all running, just at the tuning stage, hopefully first proper run out next weekend.

Well that answers that question.
