2010 Front Engine Dragster Week 2012 10 20

REMEMBER TO CLICK PICTURES FOR MORE DETAIL / LARGER PICTURE

Once again I am behind in my updates,  there have been three more meetings of the Car Nuts. I am truly learning just how much I do not know. If I do not do the updates right away they get harder to do and I forget stuff (is that because I’m an old fat guy?)

We left off with the blower spaced up with 2X4 blocks.

Car nuts meeting 10 /20/2012 had a great turn out. Lots of old members showed up.

Bob took on the task of unpacking new presents. Had a 4 inch spacer from Alkydigger, Pulleys, blower snout, two different idler pulley brackets, idler pulley and Pontiac crank snout form USA Supercharger, and a crank snout from RCD

First thing we did was remove the 2X4 blocks and install the 4 inch spacer between the intake and blower, and bolt on the snout. The spacer will need some machine work (burst panel installed and clearanced inside to the retro port on the blower.
DSC_0222_smallSteve, our technical advisor, held class on setting up a belt drive for a blower

DSC_0231_smallA couple of old time car nuts showed up, Dick and Don, and of course my son George
DSC_0229_smallAnd the fat old guy is still as confused as ever.WHAT have I gotten myself into????????
DSC_0240_smallWe tried the snout, snout idler, and crank hub from USA Super charger.We found that the crank hub from USA blower moved the belt way out in front of the engine, and would require the battery to be moved. On the really nice side, everything lined up in a perfect plain for the belt. The belt would clear the water pump with lots of clearance. The degree wheel was way away from the pointer so a new pointer would have to be made

DSC_0234_smallThe idler (blower mounted) bracket was tried and it was founded that it would have to be spaced way out to work.
DSC_0244_smallWe ponder this set up and decided that we did not like all the leverage on the end of the crankshaft, that we wanted to move everything closer to the front of the engine.

So everything was ripped back of, the RCD hub was installed on the crank shaft, the blower mounted idler pulley bracket was installed and we found that nothing lined up. The snout is too long, and cannot be used, the crank pulley needs to be spaced out by ½ inch to get the belt to clear the pump, and the idler pulley needs to be spaced out 5/16 of and inch to line up with the crank pulley, which just happens to be the thickness of the harmonic balancer retaining washer

DSC_0267_smallWith the RCD hub and degree wheel the pointer is not in a perfect location
DSC_0195_smallSo….. it actually took going back and forth several times with these setups to come to the conclusion that the hard way is the best way.So we started with this
DSC_0268_small                                            DSC_0270_smallAnd ended with this

The snout needs to be replaced with a shorter one, two spacers need to be made one for the idler pulley and one for the crank pulley, and then everything will line up, the belt is nice and close to the front of the engine and has a 1/8 inch clearance to the water pump. Now we have to find a belt that fits. In addition the spacer needs to be machined, which means I have to find someone to do it.

We are adjourned for the day, with lots of research to do and parts to find.

This is the next week’s Car Nut Update.
I am putting it here as it is almost a duplicate of last week’s except new parts have been ordered and installed to correct the belt alignment.

Below is a list of the new parts that were ordered

Ordered from Littlefield:
   Blower Snout 5.120
    3/8 pulley spacer for crank pulley
    Starter belt shield

Ordered from Good Vibrations Motorsports:
    3 Pack green gasket set for blower
    Burst panel frame with 10/32 screws
    3 pack burst panel
    4.25 idler pulley with standoff and hardened washer
    4 X 5/8 / 18 bolt
    t-nut

USA Supercharger:
    Belt, 190 tooth rubber with Kevlar fiber
    Top plate for single dominator carb

ARP:
    2 ½ / 5/8 /18 crank bolt

DSC_0302_smallWe bolted the new parts on 
DSC_0308_smallSpaced the idler pulley and crank shaft pulley out temperately and cranked the engine over to see where the belt would run 
Settled on the BirdCatcher injector hat as plan “A”

So now we are ready for some machine work next week;

Clearance the spacer between the blower and intake for the forward outlet of the retro blower, machine the front so that the burst panel can be mounted, open up a path from the front to the rear of the intake in the spacer. Machine a spacer for the idler pulley, machine a spacer for the crank pulley.
