Wonderful!

I really enjoy what you share and really like your car.

I don't want this to sound bad about the challenger, but I like your car much better and the sound much better.

Thanks.

Nice runs. 

SAME FRIGIN fuel pressure problem as before GERRRRRRR

Rather than have you rehash things for the Nth time, do you have a thread on here where you're discussing the situation and steps you've taken?

Very nice Charlie.  Good weather down there on track day?

Thanks Russ ,YES very good, right at -1300  to - 1000 ft on my runs, all that said, the car ran its best yet, BUT with my fuel pump issues I think it slowed it down quite a bit, I am Still VERY pleased & happy with the results so far, No Roll cage ,this car is a drive it anywhere street car, AC, OD, 4.10 gear, 4100 lbs ,drove to & from the track again, 140 miles, drove there, put the long runners on & let the tires down to 20psi, all of 5 minuets work,the 512 is getting tired, been leaned out so many times from all the fuel problems I have had. I am VERY Happy though !!!!!

Thanks everyone for the positive responses, I have a Tanks Inc EFI tank with a Walbro 450LPH pump, return system, at 1st I had a 30 amp relay in the glove box area for the pump, time before at the track fuel pressure was spiking 0 to 50 psi the entire run, got home & found the plug to the relay was melted some, redid the set up with a 80 amp continuous duty solenoid in the trunk close to the battery & fuel tank & put a 450 lph fuel filter on it, did lots of fuel volume test & everything looked great I thought, tank was almost full for the runs, has to be I have a bad connection inside the tank at the pump or a defective pump, will drop the tank & let Y'all know what I find.

That's awesome!!!   Love your build and your twist on things....such cool package you built and designed.  Hope you work out your fuel issues but it sure runs strong now!   Congrats.

Great launch pic 

Interested to see what you find with the fuel pump.

Dang cool car and fast too. Congratulations on the best pass yet and it sounds like it will be even faster soon.

Looking good! And real fast!

[WHITE AND RED 69]

Awesome!!! That baby is hauling!

Bummer about the fuel pressure issue but that's still a damn good time and even cooler that you drive it there and back.

[c00nhunterjoe]

Having that car lift the tires straight without a roll cage is DAMN impressive. I cant do that. Mine twists way too much even with 2x3 weld in frame connectors that are tied fully to the floor.

I was sent another picture, Had to share with Y'all, it made all the work on my street car worth it, puts a big ole smile on my face even though I still have the fuel pump issue

[kent]

[funknut]

new favorite picture ...shame no sound with that one 

[BSB67]

That's a nice pic.  What's your 660 and trap mph? 

[cdr]

That's a nice pic.  What's your 660 and trap mph? 

660 , 100
1/4 , 120

On the log the fuel pressure starts dropping off & on at about 300ft, in 2000ft air my MPH has been 123, but that was also with fuel problems.

[BSB67]

Yep. History and the data suggest top end fuel delivery.  It looks like your 660' mph is pretty close to normal, right?

What do you think is the root cause?
