Duel Relay Trans brake with a stock Converter: Before and After

[truebluedevil02]

So I finally got around to doing the trans Brake mod for our cars. I know most people that use them probably have aftermarket converters so I wanted to see the difference when using a stock converter. I have to thank Clinton2003 for helping me with this install. When it comes to electrical systems I am basically a monkey doing a math problem. The install took about 4.5 hours when all was said and done. Neither one of us had ever done this mod before and I wanted to make sure it was a clean install, all connections were soldered, and was completely hidden. Now that I have done it Im sure it would take a lot less time to do again. It looks a good amount more complex than it really is.

Everything fits perfectly in this little hole in the factory bumper support.

These are the 2 wires you cut from the harness and splice into. After we got everything connected we tapped everything back up and you would never know the harness was cut into.

Everything hooked up and ready to go.

Once it was finished I took it out to test it. Stalling off the foot brake was giving me 1700rpm before the tires would spin. On the trans brake I am able to stall to 2300rpm and everything holds. The car does get off the line quicker now and picks up much faster as well. I will be up to the track next week to do some testing and see exactly how much this will help my 60' and overall 1/4 mile times.

Huh, thought these were supposed to hold to a higher rpm?

Interesting.

Interesting.

The brake holds just fine, but 2300rpm is all the motor with rev to with the stock converter

probably stock converter that's why, nice setup!

Is there a install how to on this anywhere?

thanks for posting this Truebluedevil...I bought the relays and a Biondo TB button a few weeks back and have been holding off on doing the install. I see you have 2 red wires running across the core support to the drivers side out of the relays, seems like you should only need 1 wire to run to your trigger switch...whats the 2nd for?

Havent people already found that there are no gains to be had on the stock converter?

600rpm higher launch point sounds like it would gain to me, unless it likes to flash instead. Thinking centri at altitude it would be better with the RPM though, will find out soon. Hopefully makes for more consistent lights too

One red wire is inbound to the button, the other in outbound to the relay.

I can say that it has made a difference. How much remains to be seen.

Agreed 100% Bud. Next Wednesday we will find out.

you are a wizard.

Nice man, I'm thinking about doing this too. What are your 1/4 mike times and 60' without this?

 

[stangn]

Good to see non shop cars starting to do this mod. Now some real word info will begin to follow I hope.
Keep us informed and thanks.

Right now the car runs high 11.50 - low 11.60 very consistently with 60's in the 2.04-2.08 range. Im hoping I can get the 60' down into the mid-high 1.8 range on the stock converter.

Dang... Is the track at a really high elevation?

ANyone have a wire diagram for dumbies on this??

He's probably in Denver, so yeah. I'm not as high (no pun intended Colorado folks ) but can certainly attest that altitude sucks...

This is interesting, would love to see the track results.

Yes, I race at Bandimere Speedway in Denver Colorado. Our average DA is around 9,000'-10,000' during the summer. Lowest DA I have ever seen up here when the track is open was 6,200' DA.
