how much boost? Killer pass and that mph is fire

@turnswrench just FYI, you should always do your burnout in 3rd gear with a RMVB TH400. You can start in 2nd gear and quickly shift to 3rd if you prefer, or because of lack of water or power level but always in 3rd gear ;-)

Sorry for the delay and thread hijack. Footbrake uses ground activation for 2-step and transbrake uses 12-volt activation so you can have both options hooked up and ready to use

@olaosunt - I have my 2-step setup to activate off of the trans brake button OR it will also activate with the footbrake via a momentary button on the brake pedal (for footbrake only racing). Lemme know if you want some pics ;-)

I also have the YSI-b on standby with jets for a 150shot if I decide I want to shoot for 170mph+ and high 7s

Yes on my build I can run more boost and/or a bigger shot of Nitrous. I believe the car will run low 8s if I spray on the hit and shorten the ramp. The only real limitation is with the Nitrous, I run a plate setup so anything north of a 200 shot would be sketchy due to potential distribution...

Vortech V-7 JT-b which I think is F1 equivalent? I have it pulley’d for 20psi and car is full weight. Still a centri so I was just trying to share my experience with OP with adding Nitrous to a Centri combo which works great and also lowers IAT’s significantly.

Thanks. The 60' is boost only and not max effort. I have a high stall converter with a TH400. I ran out of time before the weather ended the season last year here in the midwest to try the nitrous off the initial hit. I have a progressive controller and was experimenting with fairly long ramp...

A little nitrous with the Centri blowers works great:

I'm not on here much lately, but I have no problem sharing any info on the TH400 swap. When I did it 3-yrs ago, there was even less info available lol. Regarding the reverse lights and backup camera with a TH400: My car was a MT82 car so I already had the manual gauge cluster, PCM, and wiring...

Yes, you shift the TH400 manually (powerglide shifts manually also).

I bought a used Watson 6-pt bolt in that I installed as a 4 point so no crazy pro-mod cage lol.

Yes, stock ECU with a quick tune revision from Lund. 6R80 records are super impressive but the 6R80 can't touch the TH400 durability and consistency

I used the JPC S550 line-lock kit, JPC S550 shifter mount, and the JPC S550 TH400 mount - all quality parts. JPC doesnt manufacture or assemble the TH400 and whoever they use I have read mixed reviews. I measured and created a 2D drawing for the drive shaft and had the Drive shaft shop make it...

Can you believe I'm still rocking the Vortech and its still a full weight PP premium car!@$%! Since I hijack'd your thread, here's in-car vid of that pass showing the TH400 in operation. I have a fist full of 8s passes now and the TH400 makes the car very consistent and reliable:

Currently running a 3.73 ring & pinion, with a 28" tire = 3,200 rpm @ 65mph. I will be switching to a 3.55 ring & pinion over the winter because I'm hitting ~ 8,050 rpm @ 161 mph as I cross the finish line and I want to turn it up some more next year. Another benefit of the TH400 is you get a...

TH400 and never look back ;-) Still fun on the street also and manual cars are really easy to convert

yes - I would pull the motor or drop the k-member. If you pull the motor you can do OPG, crank damper, or anything else you might want to do and it will be much easier

Interested - and I think we have done business before?? sending PM now

Whats the name of his youtube channel?
