- Well more firewall work today as we figure out the geometry for the proper fitment of the Hydro Boost for Ruby. We are starting from scratch and modifying everything including the brake pedal assembly, brake pedal bracket and making a custom hydro boost mount to weld onto the new firewall.
If you have a project you would like to showcase at the end of one of my videos just email me a few pics and a short description to: foothillpaintandfabrication@gmail.com
The brake system is so crucial but you took your time and gave it a lot of thought, I have no doubt it will work perfectly when all done. Nice having a cnc plasma table to make precision parts too. Great job!
Thanks
Having sketchy brakes on Ruby after all the hard work is the last thing I want. I will be testing everything several times.
I just watched a video not too long ago... part of an excellent build series over at the channel Fanatik Builds. That guy is FANTASTIC... and, in my opinion, - if not the top build series, then at least one of the top 5 build series. He's trying to squeeze an LS into an old BRG Spitfire or something... anyway, because space is at a premium he mounted the power brake booster transversely and came up with a bracket/lever to change the direction of the force when the brake pedal is applied. He managed to find room back in where the windshield wiper motor usually sits. It's quite ingenious... but seriously, if you haven't seen that build series you might want to consider checking it out. It really is excellent - inspired by the Binky build series over at Obsession Motorsports. I think your build series will probably make it into the top 5... but you haven't gotten far enough along for me to figure that out. You are doing such a thorough job and teaching us every step of the way... like Fitzee, you know?
Thanks Tyler,
You mentioned him before but I haven't had time to check out his channel. I am making myself a note right now. Back in the day when there were cab over trucks still around they would mount the vacuum booster parallel to the firewall under the dash on the non air brake trucks like you mentioned. Pain to work on but it worked. Love watching Tony use whatever he has laying around to fix rusted out cars. He kills me with that 24 grit though!
I really enjoyed this video Mark. Figuring out problems like this is super satisfying. I’ll be interested to see the clutch master go on. I was surprised that the threads were metric on the clevis.
Picking up my gas tank from Bo on Tuesday. I’ll email a photo.
Thanks for the feedback Robert. The clevis is 3/8" NF originally but the shaft on the hydro boost measures out at 9mm so I ordered an M9x1.0mm tap and die. Odd numbered metric exist, just not common. Probably will be the only metric fastener on Ruby. I have a pretty cool thing to do to the firewall and then I will get to the hydraulic clutch master cylinder.
Getting the tank dipped was a smart move, especially since you are running fuel injection if I remember correctly.
I rebuilt the original carb and will use that in lieu of injection. I’m staying mostly stock on this truck.
Picked up the tank. Looks great. A little undercoat is still attached. But it’s super clean and I’m very happy! Got back to Gig Harbor today. The tank is in the house. I’ll get the shop up to temp tomorrow and get some primer on it.
Undercoating is tough stuff but is pretty weak after Bo is done with it and should come off pretty easy. I have car parts in the house too. Once the tank is done it is one more piece of the puzzle done and ready. Must feel good to be moving forward. @@robertmazzei2412
That booster nut socket is $100.00. I hope you do not end up needing to 180* the booster for the 400 valve covers. Very nice work.
Thanks. I have heard those sockets are ridiculously priced, I think we can make one for free out of a piece of pipe laying around here. I had an 11" vacuum booster on Ruby before with a 1/2" clearance to the M/T valve covers. I haven't decided which way I will clock the hydro booster yet but once I figure out the clutch master cylinder I will know what I can get away with. Ideally I would like to put the spring housing on the outboard side which will give me plenty of room.
That was amazing stuff Mark! Way above my level. Where did you get that plasma cutter? That was fascinating to watch!!
Thanks Doug,
I got the table a little over a year ago I guess. Very helpful and will come in super handy when I start on the chassis. It is a small one but plenty for what I need to do. It is a Langmuir Systems Crossfire table.
@@FoothillPaintandFabrication Very fascinating!! I'll be looking forward to watching that in action some more!
That was awesome Mark! Did you get a new toy? I was thinking of hydroboost because I have a blower and no manifold vacuum but I have electric P/S so I'm going with a scroll vacuum pump and under cab M/C and booster. Thank you for your time.
Thanks, I picked up the Crossfire table a little over a year ago I think. I knew I would need it when the chassis work starts but is is nice for a lot of other parts too. I know you are going for drag and drive on the truck and I am no racer but don't most guys run manual brakes? Smart move on having one less thing running on a belt drive on the truck, especially as fast as it will be spinning.
A lot of drag racers run manual brakes and steering. I want the drive between tracks (usually about 200+ miles) and normal street use to be comfortable for me and the random hot chick. With the blower I can easily run a wide range of power levels. I plan to drive the wheels off it. Maybe even do some auto-cross. I have a spool and a Gleeson Torsen diff for my Frankland QC. I'm also running an electric A/C compressor from down under with an "Old Air" inside kit. I even have power windows and bluetooth radio and phone. I'll be running in the 8.50 second class (about 170 mph) and I have plenty of power so weight isn't a big factor for me. It should be under 3300 lbs. If you want to run much faster the cage becomes quite confining. I just want to have fun. Sorry so long. @@FoothillPaintandFabrication
When it stops being fun and feels like a job/chore then you went to far. So you will have a couple of different sets of blower drive pulleys and belts?@@lazyhoundracing9621
Yes different blower pulleys for different power levels. The belt tensioner has a lot of range so one or 2 belts will work. I'll have 2 fuel systems, one for pump gas and one for race gas. I'll have several timing curves in the EMS. My built Frankland Quick Change has a possible 128 gear ratios that can easily be changed in 10 minutes. Switch from drag tires to DOT tires. So 1200 HP at the track and 500 on the street in less than an hour.@@FoothillPaintandFabrication
