    Jeremiah - super well documented and congrats! It sure is nice having a car that goes as fast as it looks, isn't it? Curious - did you add the beefed up input shaft on the manual tranny?

    The rear engine weight distribution is NOT the issue. That in fact helps the acceleration. The issue are the narrow tires, and the silly awful suspension.

    Hey look, a fellow VR6 DeLorean ; )!!! You are not kidding...I love knowing I can just gently (or firmly) push the accelerator pedal and "bye bye" to most on the street. It really is an awesome feeling!

    I have not upgraded the input shaft. I have upgraded the input shaft coupler as Nicholas Roedl has performed on his LS1 converted DeLorean as well as you have I am sure. The input shaft is a whole nother level of "preventative maintenance", and a very costly investment. I know Nick upgraded to a single shaft unit, which is absolutely amazing that he designed the upgrade himself; however, the individual responsible for actually fabricating the unit into fruition has since retired.

    I do know they are also available from Martin G. at DeLorean UK. Again, the price of admission is steep at $3800+ for the part alone, and given that I am leaning towards keeping the car in its current configuration, I plan to hold off on this upgrade - for now. With my transmission now a manual, the power is no longer lost from traveling through the auto, and I would guesstimate the power has increased to roughly 240 WHP - given that the power does not have to run through a flexplate, seals, clutches, pressure-changes, other burdens of an auto trans - it is now dependent through internal mechanical means of the manual. That being said, if 240 WHP is about what I have, man, it feels way faster than ever.

    Again, I am just guessing. I need to get it dyno'd as right now it's mostly a SWAG (scientific wild....you fill in the blanks).

    Actual snippet of a conversation from Sept 2013:

    Me: Eddie, I can't wait to get the car back when you're done with it.

    Eddie: Yeah, you'll be able to give the car gas, and it won't be - like - embarrassing....

    In a straight line. When you take a corner at speed, or in an autocross setting you will find the weight distribution to be an issue. Lots of understeer.

    Agreed, but that is irrespective of having more power. Jeremiah was talking about adding more power being a problem.
