Starting to gather parts - Info needed

[bigredkacy]

Hey Guys,

Followed you all for years and now I am ready to make it happen. Building a two seater for the purpose of crawling, little mud, rock racing. Now I have no one on this side of the west coast to pull this info from so hoping y'all can help.

Since this will be a trail rig will a dual pass 31" twin fan Griffin Radiator mounted in the rear be enough?

Where should I get the steering wheel, looking at a 13" w/ quick disconnect and 14" Shaft?

Any specific oil/tranny coolers that you guys suggest for this BBF?

What stall should be in the transmission? Currently I have 1800.

I currently have two 20" coilovers in my current rig, i see alot of people running 16"s. Are the 20's just way to much for 50/50?


These are the specs so far

Dang that is big ol motor!

Joe's Racing products has steering wheel parts you'll need. PSC sells them and the steering column.

20" shocks is definitely longer than most I see. I have 14s myself.

Yeap, it was built for a 7200# truck, which spun the tires like no other. It has less then 100 hours on it and ready to be used on something skinnier.

This is the one from Joes I am looking at -

With their quick disconnect..

What I am really lost about on the steering, what CC orbital should I look into? I see alot of people selling them to get bigger

Ford power!!!

As for your steering that depends on how big your cylinder is.

I looked at the steering wheel in the link. I don't really know one way or another as far as which one to get but did you notice the weight listed at the bottom of the page?

I am looking at a 2.5" ram with a 8" stroke

 

[Eddyj]

Are there any rigs that you are using as a guide?
That seems like a lot of motor/weight for Dana 60'housing unless it is built and trussed heavily.
How many turns lock to lock on your steering are you looking for? You can use that and cylinder size to calculate orbital size.

I really like what you're thinking with 10" of up travel!

14" shocks have better spring choices available and are easier to package. If you want more travel, you can mount them on the links and pick up some motion ratio.

Do you have any pictures of your old rig?

 

[bigredkacy]

There is no real rig that I am using as a guide as of yet.

The math that I am coming up with is referenced from here

2.25 (diameter)
1.125 (rod size)
8 (stoke)

pi= 3.14

Volume = stroke * pi * ((diameter/2)^2)

Cylinder volume - rod volume = fluid volume (total displacement)

Cylinder volume = 8*3.14*((2.25/2)^2)=31.79 in^3

Rod volume = 8*3.14*((1.125/2)^2)=7.95 in^3

Total displacement = 31.79-7.95 = 23.84 in^3

Total displacement / desired turns lock-lock = 23.84/2.5 = 9.5

9.5 cubic inch valve to get 2.5 turns lock-lock.

So it looks like a 9.5 or 9.6 will be my best option.

Will the griffin 31"x19" be able to keep the BBF from overheating on trails? Is there a equation to figure this out as well?

Here is a few of the rig that the driveline is coming from

She weighed in at 7200#'s with the 60 and 14 bolt and I have had no issue with them. So with the tube chassis i feel okay for now using this setup.

521 - Going in

4 Link Done - 20" Coilovers 50/50 split travel

Here is the trussed 14 Bolt

20" Coilovers coming through the bed

As much as I enjoyed this rig, she was just way to heavy

 

[Eddyj]

Ramp champ!!!

 

[poolman]

That thing is HUGE!! :****: and shocks for days!

 

[bigredkacy]

She was fun, but was always to large... Like my ladies, i like them lighter
