Quest for 11s stock motor

[mike diesel]

99-103 mph won't even get you close to an 11.99, I think the slowest speed I've seen break into the 11's was 112mph. And that was with some pretty nasty 1.60 60's. You need ALOT more power.

How big is the pulse on your tune now? Timing?

I think I was at 111 or 112 on my 11.86 pass cutting a 1.6X 60'

Hell, I ran a 11.900 at 104mph lol let off in a bracket race

Sounds like your truck isn't setup well for drag racing

Yep.

Track bars fabtech upper control arms stock height terra gappler tires on 20's I would be happy to get down in the mid to lower 12's

Definitely not set up for low 12s, let alone 11s.

Mph?

Just over 91mph. Would have been a 113mph+ run had I not let out at the end. 1/8 was right on track for a low 11.8

Poor ol' stock motor made 8 passes on that tune just that day alone. She was a strong one.

 

[unionmax481]

2683us max duration and 23* of timing

2683us max duration and 23* of timing

Pretty conservative... Your going to need more off both with your goals.

 

[unionmax481]

What do you recommend

 

[Dirtymaxx03]

3300uS and 33* of timing. Or some bigger injectors lol

 

[unionmax481]

Thanks ill try weds at the track

 

[unionmax481]

How much rail pressure you talking 180/190mpa

 

[Burn Down]

Thanks ill try weds at the track

He's jerking your chain a little... Try upping the pulse and timing slowly while logging rail, when you can't hold rail anymore, no need to keep going.

180mpa rail.

I forgot you have a stroker pump... So it should hold rail till the rods shorten/exit. Anywho just move up slowly and work on getting the 60ft down. 60ft is the key to 11's on a stock engine.

 

[LWATSON]

Stroker pump on an LB7, not a problem but be careful my friend:hug:

 

[SickLL7Crenshaw]

Getting closer

 

[CaptPhil]

Nice, turn that tune up a little more and you got it.

 

[DMAXchris]

So close! Drop half a tenth on the 60' and youre there!
