As you who have followed my build know, I have had some start-up issues with my build.
I have promised updates but with finding out the cause of the problems I have felt that it was better to wait until I had a handle on the problem(s).
First I should say that with a full tank of gas (
) this car starts, drives, idles, and pours on power like no Cobra I have owned before. I fact any car that I have had that was not a late model car, I would say this engine and induction system is better, a lot better. More on that later.
One BIG issue I have found is that the A1000 pump is a gravity feed pump, and it does not suck, except air if it gets a big gulp of it. The air drops pressure to the Dynatek system, and it then runs bad. So I have looked into a swirl tank with an auxiliary pump to keep it topped off, but I really do not like the sound that the A1000 pump makes.
Having wanted a larger tank anyway, I contacted Rodney from this site as he had previously constructed a 22-gallon tank for his Superformance, and asked if he could do it again, except this time with a Aeromotive Stealth sump built in. So today I got the 18651 unit in from Summit (pics below) and I forwarded it off to Rodney to be incorporated into my new tank.
Aeromotive normally recommends the unit for rear tank mounting in any race car application, but this one will get mounted in the bulkhead of the new tank, as I am not crazy about the race car look.
Features include a dry primary 100 micron filter (you can change it without draining the tank), the pump is in the tank (I am told by Aeromotive’s engineer it is much quieter), and the all important surge area. There is a pump baffle that goes over the pump which I did not take a picture of. The surge volume works out to be around 5 gallons.
I very much appreciate the positive help that you guys on this forum have provided! Thought you guys might like to see
