that spike is more like an ignition coil... as the field collapses across the trans brake solenoid, it spits a secondary voltage spike back up the line.. light bulb works but just about any resistor will work also ..
Transient voltage feedback Spike. The transbrake part you buy from Holley can actually be made out of simple stuff for cheap however they do put it in a nice compact rigid package so for 95% of people I highly recommend just buying it and being done. That actually stops the high-voltage from the transbrake from frying the input by dropping down the voltage with a resistor to ground. The light bulb that you were talking about is usually done with a diode put across the leads called a snubber diode and that allows the energy that comes back out of the electromagnetic coil when it collapses to loop around and dissipate instead of feeding back up into the system as a transient voltage feedback Spike. Just think of your coils you charge up the coil it's an electromagnetic coil and when the field collapses bad as second part where it jumps over into some other windings what multiplies it but it's the same principle basically. Oh and I'm pretty sure the numbers on your bumpboxx are the milliseconds for how long the unit is shutting down the signal to your transbrake there for the larger number being a longer time moves the car further her pulse.
Man I love how you show how to do things in a turbo setup. I have always been all motor and we know that it is impossible now. So i have recently built a turbo foxbody and I have no one to ask so im learning on the fly. Thanks again
Its a known youtube fact, the more aggressive you rip your hand off the brake switch the faster it works. If you throw your whole arm off, it goes from sportsman to pro brake instantly.
glad I sub your channel, just found this. I am thinking about pulling the trigger on a turbo set up, the more info you provide the more I have learned. Thanks!
Good video. The solenoid for the trans-brake is an electromagnet, so when the magnetic field collapses when you release the button it works just like an ignition coil and induces a voltage in the circuit. The light bulb is an effective 'drain' for that voltage.
john school is always in session wen u talk racin ur trans brake release has got to b much quicker with ur index finger. hope these begineers b herein wat ur sayin thanks man nerry christmas, oh ya ohio billy with the old s-10 said he was coming to a race called dig or die here at 710 track will u b there?
Hey John! I am looking for the video that you were talking about converter flash, but I can't find it. Trying to learn more about ideal RPM for getting the car to leave as fast and smooth as possible. 1000WHP twin turbo coyote with a powerglide.
I like the TH400 2-speed Turboglide I like the Powerglide as well and both have their ups and downs but I think the longer gear set in the TH400 whether it be a 2-speed or 3-speed set up in it people mainly like them for 1/4 mile racing and like the Powerglide's for 1/8th mile racing
For sure the turboglides will help quarter mile stuff. They also work great in the 1/8 if you put a lot of rear gear in it. Allows more rpm out the back, but keeps the starting line ratio in check so it’s not too aggressive!
Thanks for this video John. Helps clarify how things are working. It was the Holley manual I read through and they kept talking about bumping forward relative to distance and I could not for the life of me understand how that would work since to me a distance is something measured in linear units (inch, foot, meter, mile, whatever) and I was trying to relate something I was under control of over a very small distance while sitting in the car. And something that was very accurate or you would roll in too far. The way you explained it, its very clear it becomes an "on/off" controlled electronically by those pulses and those pulses accurately control how far the car can move as there is a direct connection to the trans brake. And I think I got it, its the length of the pulse that is important initially, correct? As opposed to the number of pulses.
John I have access to a Borge Warner s475,the hot side is a t6 twin scroll with a 1.35 ar.on a 6 liter what back pressure could I expect. I'm looking for 1000 hp
Best racing channel on UA-cam🖒.. also i don't really understand the relation between a trans brake and stall speed.. don't they did about the same thing
Thanks! Trans brake locks first and reverse together. Without a two step rev limiter, it will flash the converter up to the stall speed. I like to leave on the two step, 500-1000 rpm lower than the stall speed. This will flash the converter and leave harder, similar to dumping the clutch on a manual.
This is great info. Thanks for sharing your set up and routines. Was thinking about your last test and tune rainout. Maybe you could find an industrial area near you to go and do some 60 or 100 ft hits to tune your suspension, tire presures, ramp up settings etc, and it would be a no prep surface. Use google earth to find a place. Thats what I would do.
I don't know why everyone doesn't run that pulse leash... your car stages way more smoothly than most.... seems like your car would work better because your chasing is usually settled when you leave ..
Because there 325$ and a simple stage is 99, or just use the Holley to do the bumping, I use the Holley for bump if you have a spare input it works great, but the tuneabilty for the leash is really nice, you get what you pay for I guess
Thanks for this video, I’ve seen allot of questions on this topic and it has covered how it works very well, one question, can you do the bump function through your Holley unit?
So I've always had a TCI Sportsman brake in my Glide and one weekend I I broke my Glide and a friend of mine loaned me his spare so I could get through the weekend. His Glide had a pro brake in it so I had the borrowed Transmission in and I checked to make sure that the brake was working before firing the car I hit the transbrake button and didn't hear any noise of the brake engageings so I checked it with my test light for power when the button was pressed and ahad power so I checked the ground and the ground was good. So as I couldn't figure it out I called my buddy that loaned me that trans and told him and that's the first time I heard that the pro brakes use transmission fluid pressure for the plunger I guess I just assumed that all trans brakes were the spring loaded type like the Sportsman valve bodies boy did I feel like an idiot. I aldo like thst with my sportsman brake i don't have to push the trans brake button to back up but the pro brake you have to hold the trans button down to back up
Great video once again John! I got a cool video of my old turbo Jeep Cherokee bumping in and yanking the wheels ua-cam.com/video/H2UMana_2uU/v-deo.html
Very informative. Thanks
Here cause of Bill!
Most technical low budget racer Ive seen. GJ
Thanks

@@TurboJohnRacing welcome
Tj, your a smart dude man,with a bad fox!
Thanks
Man I love your channel bro. Learning a lot from you

Excellent video.
I learn so much good stuff from this channel.
Cool, thanks for watching
Good vid John. Just picked up a Boost/Pulse Leash combo for my TTSaleen for 2020. Excited to get it installed so I can leave on boost!
Nice, you will like it.
glad I sub your channel, just found this. I am thinking about pulling the trigger on a turbo set up, the more info you provide the more I have learned. Thanks!
Thanks for the sub! That is awesome. I try to show everything and my thought processes to try and help. Sometimes I just screw it all up though, lol

Merry Christmas! Yes, I’ll be s as t dig or die. We are doing final testing tomorrow.
Very very informative! Thank you.
Thanks for watching
A diode is the input protection
This is awesome tech man. One question is this tho. Why not automate it since u have the Holley? Wouldn’t there be less to do?
Great info but the 6 commercials are killing me!!!!!!!!!!!!!!
Sorry, they should be the 5 second skip ones. Thanks for watching
Very informative video
Thank you John I have been waiting for this video all day
Thanks

1000WHP twin turbo coyote with a powerglide.
Great explanation.
Great info.
Thanks
The No Prep race that you're going to is it on Dec 21st at 710 Dragway if so Billy the kid from Street Racing Channel in the S10 is going to be there
Yes, it’s the same one. Gonna be fun
I like the TH400 2-speed Turboglide I like the Powerglide as well and both have their ups and downs but I think the longer gear set in the TH400 whether it be a 2-speed or 3-speed set up in it people mainly like them for 1/4 mile racing and like the Powerglide's for 1/8th mile racing

How expensive is the electronic set up like yours. Rough estimate
Thanks for this video John.

Yes, how quickly that solenoid cycles will dictate how far the car moves with a single pulse

Do you leave against the convertor or below your stall speed to flash it?
If so how much below the stall speed do you set your 2 step to?
Cheers
Below stall speed do it can flash!
@@TurboJohnRacing thanks for the reply mate 👍

We have another chance to test this weekend
What trans are you using ?
I don't know why everyone doesn't run that pulse leash... your car stages way more smoothly than most.... seems like your car would work better because your chasing is usually settled when you leave ..
Because there 325$ and a simple stage is 99, or just use the Holley to do the bumping, I use the Holley for bump if you have a spare input it works great, but the tuneabilty for the leash is really nice, you get what you pay for I guess
I run the boost leash pulse leash combo! Leash is the best company I have ever dealt with!!! Best costumer service period!
I love the pulse leash
How does the AC work
Not good enough, lol...
Use a diode on the brake and you wont get flux spike
I love this guy . Will you be at 710 this month ?
Yes, on Dec 21st
Thanks for this video, I’ve seen allot of questions on this topic and it has covered how it works very well, one question, can you do the bump function through your Holley unit?
I don’t have enough inputs and outputs left to bump. I have the HP, if I had a dominator it could do it.
Iwas guessing that was the case. Thanks tj, can’t wait for the no prep action, love watching those type of videos.
Thanks T J. Their are people that charge $ for your teaching sessions .
What is a good price for a used powerglide?
It depends on the internals, start case stock planetary usually go for 1200 to 1500. Ones with a good cases an aftermarket planetary’s, 2800 to 4000
Hey John I always foot brake but if I use my transbrake should the gas pedal be on the floor or just push it till gets on the Rev limiter.
Yes, go 100% throttle when on the trans brake
Make sure you have a two step, not just a rev limiter.
Which bump box would you recommend? I’ll be running a single turbo with an eBoost2 and TH400. I’ve heard good things about the Smooth Stage bump box.
I love the pulse leash
You never showed the roll control deal. Great video as always tho, reminds me I need all that shit. But I'm still having fun with the footbrake lol
I forgot about it, I got distracted.
Bumpedy Bump Bump=. Gay!!!
LOL, you must be a Nitrous racer.....hahaha

John, are you running the classic 1.76 first gear in that glide?
1.80 straight cut
Great video once again John!
