Fastest 1/4 mile time w/stock converter,,no nitrous

[It's just a six]

Hello all,
I am curious, what is the fastest 1/4 mile time,no nitrous w/a stock 2100 RPM stall converter?

Syclone or Typhoon.

Thanks

I believe Josh Straub (Tooky Cat) went 11.7x with a stock converter and a pte 52? Before I had all my troubles with the 700r4 I went 12.38 with a stock converter/stock turbo

12.4 stock turbo/converter.

what size injectors are these stock turbo records with cause my stock ones seem to be maxing out at 20 lbs

The stock turbo records were done on stock inectors. I am pretty sure Tooky ran his 11.79 on stock injectors as well.

what was the fuel pressure at?...i need someone to tune my truck

the stock injectors are around 30lbs and stock fuel pressure is like 42 w/o the boost/vaccum reference, so if you have 20 inches of vacum at idle, fuel pressure is 22 pounds and at 15 psi fuel pressure is 57 pounds

Jeremy is running around 50psi base fuel pressure and a lot of meth to add extra fuel back in.

I ran 11.80s with stock injectors @ 62 psi base. Need a really good fuel pump setup to support 80 psi + of WOT fuel pressure.

at what pressure do the stock injectors go static?

i have to look at the datamaster log, i have to make a new one also because i have since got a new delco fuel filter and had the fuel pressure reset probally a little higher then stock. i have a walbro what of fuel pump do you need?

"Static" refers to the duty cycle of the injector (ie, 100%, full open), rather than the pressure.

Pressure limitations almost always come from the pump- All pumps degrade in flow as the pressure increases. The point where the pump's flow rate drops below the flow rate of all 6 injectors is your maximum allowable pressure.

i thought there was a fuel presure that the injectors would be forced to sty open. over 80lbs was hat i was thought

I am not sure about our injectors, but usually people run into those problems are with FMU's. I know some of the GM V8 TPI injectors in the 80's stuck open at 70-80psi. The later designs were better and didn't have those problems, I suspect it isn't an issue for us. I would more worried about the Fuel pump keeping up past 80psi than the injectors.

my truck i have ran 62psi base pressure and the gauge goes past 80 with E-85 and 22 psi of boost on stock injectors. but....i know they are going static at the top.

It'd be nice to see more trucks here

What do the last few post have to do with 1/4 mile times??

Re: Fastest 1/4 mile time w/stock converter,,no nitrous

My best is 12.80. I have plugs out right now that are showing rich. FP is down to 40 and I spraying with boost at 18. Still tuning... Wide Band is helping a bunch.
