While I dont own a car with these houston upgrades, I have ridden in 3 cars with the new engine, and driven one of them (the 5-speed demo one during the open house). Quite frankly, I dont like it. It really doesn't "feel" all that much faster to me. While I have no doubt that one of these cars could easily take mine in the top end, a 0-60 race I think would still be pretty close. One of the reasons I theorize behind this is the high-geared transmission. The new engine seems to put out most of its power at high RPMS, but seems like it has lost some of its torque. So with the tranny geared so high, the engine strains to get up to where it can do some good. While this may be fine for some people, if I'm gonna put over $5000 into an upgrade, I want see some low end improvements with the torque band. (Please note how I stated THEORIZE. I dont claim to have any facts on this, only what I have personally experienced. But I think Houston's power graph is misleading, there should be a separate line for the torque curve. Where is it? Or was it to embarassing to put on?) Don't anybody start blabbing to me about how the DeLorean isn't meant to drag race. I know that. I didn't buy the car for speed. But if I'm gonna spend thousands of dollars to theoreticly make it faster, I want to feel that speed. There are three things I have done to my stock engine to slightly improve performace. I removed the hot-air valve on the air intake and replaced the line with a single piece flexible hose. I also have installed a Direct Hits ignition enhancement system. And most recently, I installed a "free- flow" CAT (if you catch my drift). With all these in place, about 2 months ago I raced a semi-local owner with a stock engine. Despite both of us having terrible launches, I still "whomped his butt". This is the kind out output I would hope to have seen in Houston's new engine, but it sure didn't seem like it. Now I have not actually raced a car with this upgrade, but if the local MN owner with the upgrade sees this post and would like to go at it next spring, let me know! ;-) This kind of race will either prove my theory, or prove me wrong. I actually hope it would prove me wrong, but I just have some big doubts about that. Sorry to have seem to gone on preaching how bad houston's new engine is. I dont think its a bad engine, I just personally dont like it. About your window question, you should check out Bob Brandys car and see what he did. (www.delorean-midwest.org) Expenive, but interesting nonetheless.
