Derek, have you tried any of the 2-step options?

Like? I mean I use the 2 step to launch off of. I bring timing down to 0-1 degree as wellThis thread seems to be a bit relevant https://www.yellowbullet.com/threads/building-boost-on-footbrake.2357586/

If the rear tires aren't turning they won't push the fronts through the beams.

Correct. I was agreeing with your post that I quoted. But the only way to stop the rear wheels from turning is a drives shaft brake, that I agreed with also, or a double caliber setup like Jamie mentioned. Drum brakes alo e aren't going to cut it...
Truck does best with least amount of timing. I just can't make it fire after top dead center. Part of the reason I am going CNP. Like I said I pull down to 1 degree of advanceIt seemed some of those guys had luck changing the timing around to get more boost. Just curious if you’d tried that.

It would really just be lying to the ECU. I could set dizzy at say 10 degrees and tell computer it's at 8 it something. That would let me yank 2 extra degrees out. But hopefully when I get the CNP conversion done I can command whatever I want.Can you retard the timing at the distributor to get it where you want it on the brake and then add it back in the tune for when you aren't on the brake?
What rpm does the converter flash to when you stomp the go pedal without being on the brakes?I can get to 3k as well but I would like to get to 3500 on stock motor. Got a motor being built that I'm sure will get to 3500+ but that won't be for quite some time. Trying to get into the 1.4x 60' on boost if possible.

I would have to check the logs to see what rpm it gets to before I start moving. I can brake stall to 3000 rpm. It is a 3500 stall but it is built for my future motor which will make alot more power.What rpm does the converter flash to when you stomp the go pedal without being on the brakes?
I’m curious to know.
I had a 3600 stall in my c4 but it would flash to 4000 and hold until the transmission caught up to the engine rpms. IIRC I could easily hold it on foot brake up to 3500 or so. And trans brake into high 3000’s
Yeah I usually leave on a 100 shot. Stays on for less than a second. Been 1.47 to the 60' when I ran 6.53. last time out with new trans I ran 6.59 but didn't use any nitrous. 1.67 60' was the end result... Turtles leave harder than that lol. Next time out I do plan on spraying it again. Would like to break a 6.39 on a stock shortblock.Adding the N2O to mine took care of any boost building.
Nitrous will definitely spool a turbo in a hurry. I'm hoping my new motor getting built will spool my planned turbos better though.I can't remember if I went 100 or 150 shot, but either way I was ready to try more. I had mine turn off at 8psi boost,same as when the W/M started.
Looks like I'm going non intercooled on my current build, so a good chance it might get a shot of juice also.
What’s the new set up and who’s building it? Sorry if I missed it somewhere else.Nitrous will definitely spool a turbo in a hurry. I'm hoping my new motor getting built will spool my planned turbos better though.
No you didn't miss it. Wasn't going to do a build thread most likely. I got ZSR building a 427 with all the good stuff. Man o war block, solid Roller cam, hi port 225 heads. Going to do twin 67/66 precision's with it that I will fab. Motor should be done in 6 months or so I'm guessing.What’s the new set up and who’s building it? Sorry if I missed it somewhere else.

I may snap a few pics at some point. I will be using this though.... Shearer fab intercooler for Holley base.
Way cool looking part.I may snap a few pics at some point. I will be using this though.... Shearer fab intercooler for Holley base.
