DR question.........sort of??
1. The DR mod works by causing a very[U] high ohm loads. which in turn causes the tranny to increase the fluid pessure to max......correct?
2. Well if (1) is Correct then it seem to reason that you should be able to control the amount of pressure in the tranny by increasing and/decreasing the amount of ohms in the DR. and therefore the tranny sees...correct?
3. Which in turn sould give you a variable pressure?
4. So as and engineer by training what is to stoping me from creating var. ohm load. DR. which would change the line pressure based on infomation from the tps? Is there something I'm not seeing? If anyone in here knows why this would not work please let me know. I haven't yet bench tested the DR so as a right now the ohm loads are unknown.
5. Also the DR also connects to the fuel pump. Does this affect it in anyway(presure up/down)? Will it change the air/fuel mixture?
6. If I was to make such a thing how many poeple would be interested in it as a plug and play device?
7. Or Am I just

Yeah I remember him talking about doing this before. He has a large thread in the nitrous forum about the DR mod.

Yes, actually its makes a whole lot of sense that it should work, unfortunately it seems like it acts just like a switch, its either on or off when you change the resistance. You can gradually change the resistance and bingo when you get to a certain point it just completely changes.

Actually I like it being full on at WOT and stock the rest of the time. I shifts fine at part throttle so I really don't want to change it.
I have had three 4th Gens and one 5.5 Gen and the 5.5 is the slowest by far at shifting and the 95 lsd is the fastest. I took my old 4 Gen 95 which is bone stock to the last race of the season and fixed up a DR switch and couldn't believe it gives a really healthy chirp on the 1-2 shift even with slicks. The 5.5 wouldn't even chirp with nitrous on the 1-2.

Its been about 3 years now since I did most of my testing trying to find a way to control the pressure and haven't persued it any further because it does everything I really want it too.
Have been looking at the TransGo shift kit and was going to install it but really don't see how it would help me with my requirements. However they are pretty inexpensive (about $50) and apparently work well for those that have installed it compared to buying the regual VB mod.

I have the DR on a WOT switch and i totally love it how it is. Like it was said above Jime tried controlling the resistance of the resistor but it did not work, in my car as you accelerate the shifts get firmer and faster, and when i floor it without DR mod. it shifts kinda hard but i guess not the FULL line of pressure (probably about 90% pressure). thats wen the dr mod comes in handy. in otherwords, to my understanding the drop resistor already changes the resistance depending on the TPS or the RPMs. the best thing is to just use it on a WOT switch like I do and jime as well had it like that.

Alternator/Prop Solenoid
Well, i might sound like an idiot newb by saying this, and that is because i am. But could you somehow put a "proportional solenoid valve" in there and somehow wire it to the alternator, so that the faster the alternator belt spins, the more drop in the resistor you have? does this make any sense or not, but again, i'm an idiot xD. if you do get this thing up n running, i'd be interested in buying it!
