All 3 oem brands have and still use a 13" l/u convertor and when those guys loss thier clutches in the l/u thier back to a fluid coupling design, and from what most say they suffer greatly when thier gone. I proved to myself that the fc design can be made much more efficent in a low stall speed unit in a high torque 12v but soon as I loosened it up to spool larger turbos the efficency went out the window again even being 13". And when I say loosened it up I'm meaning anything past 3k for sure. Remember also how Scotts and John's cars sounded down track with a small converter and glide simular to the dr p truck; like they were hung against the governer and the engine didnt pull down at the shifts, this isnt taking anything away from them but only suggesting there was pleanty left in them If locked up.

It’s not really slip, its stall. A torque convertor does just that multiplies torque. This convertor works really well covering up the lack of acceleration of a diesel in a light car. It locks up within 6% thru the traps. Coan makes some of the best convertors in the racing world.
As far as gear change, you should just see a slight change in tone of the motor.

On my comp convertors I use either Coan or A-1 they are the only ones in the country on 9000+ stall convertors. I have a over drive unit that is almost done that will over drive the convertor 50% and let me run 7 and 8 inch convertors

Doesn't seem feasible a 7" converter could handle 1500hp.

I understand that it's possible, just having trouble wrapping my head around the idea.

The convertor is sized and matched to the power band of the motor. If I decide to run B/DA which is a Pro Stock 500 inch motor, it will use a 7 inch convertor and stall around 9200.

If you over drive the convertor you reduce the torque by that % as well. Dmax power at 5000 rpm’s with a 50 % over drive will be the same HP but 2/3’s the torque. This would be 1400 hp at 7500 rpms that is smack in the lower end of a 7 inch’s efficiently band.
To make a maximum effort convertor work you stall it in peak power. let the car come to the convertor

The 1.80 is the best gear for strength, but I would like a lot more 1st gear, they have a new 1.89 that required case machines to fit that is stronger then the old 1.89 and 1.90’s. I might consider going with a Bruno Liberty, then I could get a 2.60 to 2.75 low to move the mass. . I run a lot of rear gear as well, to make up for it, and it might run out of rpms before the traps, but there is no E T to be gained on that part of the track anyway. I also run a smaller tire that will grow

nothing wrong with shifting that quick. it moves the mass. I used a 2.75 low in the Dr Perfromance truck .
a 2.10 THM400 is great , but I like the GearVendor overdrive with a Power Glide.

Mike Woods told me he got his 80e to leave off the brake in 2nd though so he found something in the VB that we missed or overlooked at the time. Something right around 2.1 then 1.1 would work just perfect.

Also since the new release of the aftermarket Reid 400 case thats way over due, it looks like a 2 speed 400 is going to get popular. Heavy internals plus this would give me a 2.10 then 1.1. Humm
This is good news for me.

Lookin good Greg! I like the new Internet persona as well. Keep the pictures low and recent, and keep the updates going on the rail without getting too far off track, and I think you'll earn more respect than you already have. It'll be awesome to see it finally go down track, in my opinion we can never have enough diesel dragsters!

Come and hang out with us, we will be running Top Dragster, competition eliminator and Super Gas. That is a good track, and will take anything you can throw at it, but the air always sucks. DA is usually 4000+ feet
