Evo X upgrades

And the fueling system grows, lol.
It's like a tumor, for your trunk.

Bah, I haven't decided how I'll go yet. I'm looking around at options. Weldon got back to me and said they have many people road-racing with their 2015 pump...it was more or less designed for that since it's continuous duty and supposedly has no flow drop off all the way to 160psi, which is redonk.

Another thought is that the problem is actually related to fuel pickup and that Full Blown hanger. If the surge tank were to empty then it'd suffer a fuel pressure problem that'd also solve itself once the tank refilled. The symptoms don't exactly make sense for that but I will unload the hanger if a new pump setup doesn't square things away.

And here we are again, both of us back to where we were the same time last year :)

RR X's are cursed.

I got a few laps in. A $500 visit for a dozen laps isn't a great value but it's a good excuse for wings & beer with my brother. :)

I've been talking to Weldon today and they are very helpful. I think I'll order that up. I will also set it up so I can easily re-enable the second in-tank pump the next time that I'm at the track.

I'll keep plugging away at it. It's too much fun not to.

How about selling your FB hangar for a stock housing + cash, then going with a slightly simpler setup? DW300 feeding your surgetank which then feeds the injectors with the Jays?

The stock pump should fill the surge tank just fine. I want to keep the FB hanger if it isn't the issue because I like AN fittings and it'd require quite a bit of rewiring to go back to stock. I've never been comfortable with the BAP...I'd rather have a pump that actually meets the demand.

I'm not aware of anyone that has done a DW300 pump, either. I'll let Scheides be the guinea pig on that. If the 044 isn't enough for my setup then I doubt the DW pump would be, either...they are both 300lph pumps.

You need a level indicator for your surge tank I think :) Then you'd know exactly what the problem is.

haha. Wouldn't that be nice? You'd pretty much need a surge tank with a fuel level sender built into it, which doesn't exist.

I'm going to order a Weldon today. If that doesn't solve it then there's nothing left to do but get rid of the in-tank hanger. For what it'd cost me to get a stock hanger it might make as much sense to find someone that can sump the tank for me. I'll ask around about that when it comes to that.

A flow chart for the Jay Racing "342," which is their competitor to the DW300. I've ordered one of these and I'm going to pull the two 255s out of my Full Blown double-pump that is in the tank. This beast flows over 400lph at low pressures (to fill the surge tank) so having duals would be silly. I think I'll just use the Hobbs switch for the second pump to activate the Weldon pump speed controller when I put that in.

I've been doing a bit of research into installing a collector in the stock gas tank--either a plastic ATL one or having something welded into the tank. I hope it doesn't come down to that kind of craziness.

A custom version of this that is small enough to fit down the pump hole is a thought:

I also found out that they make a complete fuel tank replacement cell. It's only suitable for track-only vehicles and race gas. It's interesting, nonetheless.
