You won't get better customer service than Atomic on here. He got my L86 with a 218/226 cam dialed in great.

Pat G in Victoria TX. He has done mine for a while now. Just shy of 700 to the tire with all the mods. He did my buddy's truck as well and with cam headers and converter he laid dew 425 to the tire on 93. It on E85 now and it makes more. Pat is conservative as well.

Slapps do you have a build thread. And what fuel lobe do you have and are you just running LT4 injectors and not LT4 pump?

Slapps74

No, No build thread. LT4 Injectors, +32 on the fuel lobe and low side upgrade. It ran 15-16 psi for a long time before I broke a piston about a moth ago. It wasn't out of fuel either. On 85 @ 6800 rpm and like 210kPa or (15.5 psi) i was at 29% duty cycle on the injectors with like 75+ psi on the low side and 2900 + on the high side fuel pressure. New motor will need the LT4 high side pump though...…..

I was always wondering with my 32 over fuel lobe if I would be out of fuel without the LT4 pump at around 600rwhp on my 6.2. I figured I would need the low side and LT4 injectors. Anyway all future plans, I want gears for towing and my heavy rims and tires first. Then I'll boost it once it's paid off.

93 you will be good for sure. I was surprised how far it has gone on e85 with the stock L83 high side.

That's crazy it was only at 29% at 15.5 lbs with the fairly little you did to the fuel system. Thanks for that info too.

Im curious if the LT4 injectors or the fuel lobe made the most difference. Either way it's obviously got a ton of head room with that setup.

What all is done on the low side?

Slapps74

It was the injectors. I was pretty much out of fuel with the stock L83’s. No way e85 was even an option before the LT4’s. Walbro 340 external on a hobb switch set at 5 psi. Armageddon Turbo has a low side in tank 460 or 465 that I would if they had had it before I would have just done that. That should be enough low side for 900 to 1k on the low side even on E85.
