Juiced Coupes 306

Nice!  Glad you got it back to the track!

Got the new fuel pump installed today, along with a wiring update.

I got a deal on a nearly new Holley Black pump, which should be more or less equivalent to the Aeromotive pump that was on it before. While the Aeromotive pump served me well, I just can't see spending $200+ on a non-serviceable pump, whereas Holley will sell you damn near anything you want.

I had also been using a generic relay from the parts store, so I took this opportunity to replace it with a waterproof Bosch piece. After taking everything apart, I could see some pitting on the terminals of the old relay.



Since I already smelled like gas, I decided to go ahead and remove and inspect all the braided lines on the car. I have been thinking about replacing all of the hose on the car, so my intent was more to make sure that none of the hose ends were galled or otherwise needed replacement.

It turned out that the lines and ends were all in good shape. The inner liners are still pliable and I didn't see any signs of degradation. So I cleaned everything up and put them back together with Corrosion Block spray.

There was one thing that I noticed. My car has a few different brands of hose ends on it, depending on what was available at the time. The newer ones are Redhorse brand. IMHO, they are much better than other brands that I've used.

Not exactly a update on the car but this seemed like the best place to put it.

From the "Things I enjoy" thread:

Finding stuff that you misplaced or just forgot that you had.

Last year, the shaft bearing on my Aeromotive fuel pump went out and chewed up the seal with it. At one time, I knew that I had a parts pump laying around (from a friend's car that went underwater in a hurricane) but couldn't locate it. I figured that I must have thrown it out.

Anyways, I put a Holley black pump on the car and have since bought a Mallory Comp 250 for future plans. As luck would have it, I stumbled across the old parts pump while digging through some boxes. Even better, it had two regulators laying there with it.

Between the two pumps, I was able to salvage enough parts to build one good one (I think). When I get bored one day, I'll hook it up to check pressure and flow.

One of the regulators is a very old Mallory 2 port, not even the current design. Nobody at the current Mallory/MSD/Holley even knew another design existed. So, I made a thread on the YB to see if anyone knows if the new style kit will work on the old regulator.

The other regulator is a Summit brand two port, made from polymer. I remember that I cracked the housing by over tightening one of the fittings. I replaced it with a Holley 803. I thought that it might use a Holley sized diaphragm but the holes don't line up. So, if anyone has one of these and needs parts, PM me and its yours.

With a few modifications, I was able to retrofit the old Mallory regulator with the new style kit.  With the exception of not being able to adjust above 7# (the new kit has a flat diagram, compared to the original concave design), it worked quite well. While hooked to my flow gauge, it was able to adjust to below 3# and didn't have hardly any creep when the valve was closed.

I tested it with the above mentioned Aeromotive pump, which also seemed to work well. It primed fast, made no abnormal noise, and didn't leak.

So when is it test time ?

So when is it test time ?

If it happens this year, likely late November.

I start 7-12s in a few weeks, until June. Then the same thing in the fall. So, I'll be working during the good weather.

I need new tires right now. I couldn't bring myself to putting a few passes on a new set and then have them setup in hopes of getting in a few November passes.

I started to go anyways the other day on my worn tires. Then I found out that they are doing track renovations. My other local track has been running a bunch of no prep stuff.

I don't know. I don't typically like summer racing, but I may do it anyway.

I've definitely thought about it. Its probably closer 1.5+ for me, assuming that the parkway isn't backed up.

I'm also not crazy about towing through the tunnel and across the parkway. Its like people forget how to drive when they get there.

After watching all Rodney's videos, I'm definitely going to make it over there one day.

I think I've got everything that I need to revamp my fuel system. I'm on straight night shifts until June, so I'll only have an hour or two at a time to work on it.

After my Aeromotive pump died, I kept an eye out for a better replacement. I got a deal on a refurnished Mallory Comp 250. Then I got deals on a nearly new Holley 704 and brand new Quick Fuel 803 regulators. I also picked up a new MagnaFuel filter to replace the Earls filter that is currently on the car. The MagnaFuel has a little smaller micron rating but has a ton more surface area.

At first I was just going to install and/or replace only the plumbing that I had too. One thing led to another, and I decided to replace everything except for the fuel cell and the aluminum line that runs along the frame. Both of them will require modifications as well.

My car currently has a mix of Earls (mostly), Aeroquip, Russell, Redhorse, Big End, and Jegs hose ends on it. The Redhorse are by far my favorite and that will be all thats on the car afterwards. Most of them are full swivel and are sooooo much easier to assemble than most of the others listed (Earls are the hardest).

All of the stainless braid is coming off and being replaced with nylon braid. I bought the -6 Vibrant first, and planned on using that hose for the whole car. Then I ran across an online speed shop that had really good deals on their house brand hose. It had several good reviews, so I bought it for the -8 and -10 lines. Most of it will be covered in heat sleeve anyways.

I also decided to replumb the regulator manifold. The old one is made mostly from brass fittings. The new setup uses a -10 MagnaFuel manifold and the associated fittings for it.

If anyone is wondering what the green thing is, that everything is sitting on. I'm finishing up a new transom for a 14' aluminum skiff that I recently acquired. Its three layers of 1/2" exterior plywood laminated together, sealed in four thick layers of marine epoxy resin, and primed/painted to match the boat. I'm also adding a section of aluminum flatbar across the top, where the motor attaches.

I've got pics, but the damn site is acting stupid with uploads tonight.

We're going again this Sunday, traffic should be lighter on the weekends

I'd drive over, but..........

I'm on straight night shifts until June

And while this Sunday is actually my day off, I don't think that my wife would appreciate me spending my one day off in Pensacola, at the track.

Understand, I think they do one more test n tune on sunday this month, they've been alternating Friday nights and sundays every weekend. Starting in May it'll be Fridays only, and I work at night too, so the only time I'll be able to go is when they let us make passes between rounds during bracket events on Saturday nights.

Mobile may be another option. They are back open, under new ownership. Now using the name US90 dragway.

I don't know if it's been completed, but I heard that they were extending it back to full 1/8 and were extending the shutdown area.

I think that they are running grudge racing on Sundays.
