So the first VB is done and sent back to test vehicle number one. There will be three. I'm getting feedback and testing various VB configurations in 3 situations...a stroker 4.0 with other mods (daily driven), a stock engine (also daily driven), and a pure track/race vehicle. This is just to start. I'm going to offer two variations, each totally customizable to the users application. I'm about to go blue, and new posts with users perceptions will be forthcoming. I will be recording data and giving actual dyno/mathematic/graph results soon to add to the users experience. I am not Bose. While the users end result is paramount, the numbers and math should all coalesce and jive...know what I mean?
While the upgraded VB is ready for sale and you have options based on your concerns, I ask anyone interested to wait until I quantify the results from the 3 test vehicles so I can make the best judgement calls possible when answering your questions. Some of you will need higher line pressures, some will not. Some of you want to lock in 1st gear in the 1-2 shifter position, some do not care. The VB will be tailored to each individual, though for the most part one of two configurations will suit your purpose. I am comfortable stating this much: If you desire 1st gear lock-out, it will require purchasing the Transgo Kit. I'm not spinning anything up on a lathe that Transgo already makes.
On a separate note, this is where I am on the main line pressure issue: I want a formula. My goal is to be able to plug in the estimated crank HP of an engine and based on the output of the function, determine the appropriate K-factor spring to install in the pressure regulating valve assembly. Why? Simple. Higher line pressures will allow for increased torque capacity of the trans. There is a drawback, however. Increased line pressures may require more crank HP to produce, and this will also increase transmission fluid temps. I want to give you the perfect balance for your application, and MATH allows me to do that.
Obviously, if you have 600 crank HP and the clutches slip at 400, it is worth 10 crank HP to increase line pressure and transmit 530 WHP to the wheels, right? 600 -10 = 590, and 590 thru the drivetrain might come out to 470-530 RWHP. Simple arithmetic. We aren't even into the math yet. Also, please realize that I am making numbers up in that example, so please don't get weird on me. Point is, if you don't need to increase line pressure, then DON'T. If you want crisper shifts and crisper TC lock-up, then you don't need the Transgo kit (once I have my formula then I won't need the Transgo Kit to increase line pressure the way I want to). If you want 1st gear lock-out and higher line pressures (or ANY track/crawling/off-road perfomance application) then you want to add the Transgo Kit to the cost and the mods.
Pricing is in the works. Ballpark $175 plus shipping here for stage 1, and approx $300 plus shipping for stage 2. If you provide the Transgo kit yourself, then you can get a stage 2 upgrade for the stage 1 price (WHEN FINALIZED). Initial purchase of either stage will include me making adjustments to the shifts ONE TIME...as long as you are willing to pay for shipping to me and back to you.
Any VB I do can and will be custom tailored to each customers specific application.
Here we go.
