Just so everyone is aware, recently I ran into a bit of a situation with my f*cken fuel gauge sender. It said I still had fuel as the gauge was showing between the red line for empty and the next white line. Is this an eighth of a tank?

Anyways because I have the process west surge tank with the pump outside, I noticed a different noise that morning.

I thought the surge tank pump was playing up. It did this for about 5 minutes or 3km, then I ran out of fuel and the car came to a stop.

Warranty job at fraud got the sender fixed or replaced.

Had I experienced this before hand, I would have known that my tank was empty and I would have pulled over right away.

When there is fuel in the tank, the surge tank is quiet. The only time I hear the pump is when it is priming up and when I run out of fuel in the tank.

That being said I am glad I had the surge tank because in those 5 minutes I did give it a bit of WOT.

Next time I hear that noise I shall pull over and fill up.

someone once upon a time was telling me surge tanks were a good way a few years ago to get big fuel pumps in the system.

now that tuners have all sorts of cool technology in regards to logging fuel flow and the like; the issue with surge may have just been they couldnt get a big enough intank pump to work. I know Ratter has some of these cool tools in his shop; he would have more insight than me

I have also been reading a bit on how fuel temps are affected with surge tanks if not paying attention to the rest of the system

Aftermarket Industries who sell a lot of fuel systems around the world are releasing their own twin pump cradle setup shortly. I am keen to try one.

But on a serious note stripes

we need data on why!

I've heard of grenaded Ts with surges.

without data it's becomes silly to postulate why it blew up.

Every serial killer drank water therefore water causes serial killers (I know it's an exaggeration but it's an attempt to demonstrate my point)

True, it's worth remembering that correlation does not imply causation in either direction.

True but 20 seconds is a long time to be on hard acceleration and full boost

I bet you sh*t Steve when you went to to 1000m sprint. Bet you backed off. And I don't blame you

Not true. Our Nizpro car has a custom Intank swirl pot and an Intank 044 (2006) The difference is the inside of the tank is full of open cell foam to stop fuel slosh.

Remember years ago tanks had internal baffles. The ford tank is a poor design for performance applications

how different are the tanks and cradles in the coyote cars? There's a few out there running sh*t loads of grunt and they don't typically do the turbo surge tank...they don't fit

Yeah the issue of lean out was brought up pre event by Luke who advised 20 seconds+ of WOT is a strain on a fuel system. I hadn't thought of it. We tried to get an AFR gauge he was willing to lend me in there but I couldn't get the bung welded in time.

I did indeed back off at 800m during my solo 1000m run primarily due to brake fade concerns but also rolled into it a bit instead of hard launching to reduce fuel movement and time spent at WOT. Timing gear f*cked me anyway and I had to rely on OBDII data for top speed result (223kmh vs 222kmh on 800m drag races). The true 800m runs were roll on from 60kmh drag races so no launch effect there either. Felt confident enough to go WOT for 800m in those circumstances. Was a small gamble though on my part.

I stopped playing entirely once I got a bit under half a tank. Need something better for next year...but back on topic, interested in the Coyote (Miami) question!

I was just stirring the pot and sitting back to see what happened.

There's a big thread on this going on over an AFF at the moment...It's getting pretty heated and CAT-man Dan is putting his money where his mouth is to purchase a KPM unit to test KPM's claims of it's "benefits over surge setups without any downside" (paraphrase).
