Back to the Dyno 3-22

[Pops Fun]

My winter project was new 60# injectors, 2.85 (from 3.3) vortech pulley, fuel rail and Snow Kit.
Went a week ago to be tuned and ran out or MAF. Put a BA 3000 on yesterday. They are "fitting me in" after someone else.... Hope his goes fast. wish me luck.

Hoping for 550 or so.

Ran out of fuel about 5200rpm... stock lines, walbo 255 and t-rex.. 60# injectors.

what did it make up until that point? what are your plans now to upgrade the fuel?

60# injectors and it ran out of fuel? that thing must be a beast. do you think the lines are the bottleneck at this point, or the injectors, or the pump?

It could be either but I think it is the pump and lines At about 5200rpm the fuel pressure started slowly down. The injectors looked ok at that point. Shop owner called Aeromotive about there 340 stealth and they decided it would do it but be close to it's limit... if I pull the 14# of boost I think I will.

Hell ya...sounds like a screamer...

it was a hot run so the computer was taking timing out so we don't know 441 was on the dyno, but with the timing pulled back that is not representative of what is available.
Plans..... darn wish I knew, a little down in the dumps, two choices I see.

1) put the 3.33 vortech pulley back on and tune with it and the meth. HP who knows
2) Spend the money on a fuel system........ They suggested dual walbo 250's and -8an line. I will look at that but may go the pulley route til it's done.

Suggestions... Glenn want 1300.00 for his.. too much.

I'll be disappointed it it not over 550 .... closer to 600 would be nice. They were pumping me up at the shop talking about 600...

with the fuel upgrades you mentioned i wouldn't be surprised with 600. i would put the smaller pulley back on and get it tuned up. once you up the fuel system you can always have the tune redone, but at least the leg work will be done. in theory it would be easier because all the tuner would be doing was making sure it was still good; maybe adjusting a bit more on the top end.

I think you are right.... step back and collect some more parts....

Bought the fuel system... no limits now...
Glenns performance dual walbro system.

Now the waiting begins...

Hi
Fuel system came in...
Worked with my son Jay til close to midnight last night... Got the pumps mounted to the tank cover... FYI... Washed and painted existing cover... was surprised how well the paint looks..

Got the new fuel regulator installed and the return line installed...
Pics later..
Installed the new rails.... already had Mallory rails nothing like doing things twice..

They miss the MSD distributor easy... might need a 45 degree fitting to miss the coil..

They want the feed lines going up the drivers side that will be today's project.
i'll take some photos of the tank hanging today... tired last night.

making good progress!

making good progress!

Thanks... Finished. Not the water pump is leaking... never ending.

Have a dyno appointment on the 29th.... might see if I can move it up..

Finished Saturday and put 5 gallons of 93 into tank (20 something for 5 gallons eek) and it started up after turning off 5 or 6 times and setting fuel pressure to 38 with vacuum line off.
