I have never driven a 914 but have always wanted one. I will be making a purchase in the next 5-8 months. I am trying to get a feel for how much power/torque a 914 might have in relation to what I have now. I am currently driving a BMW 328 (190hp) and am getting about 16 +/- pounds per HP with torque peak around 3-4K rpm.

My question is: For a given motor what could be expected. I guess that a 1.7 puts out about 70hp(31/lb), 1.8 - 80-85hp (27/lb), 2 - 95-100hp (22/lb). I am interested in the 6 conversions. What is typical or conservative for a 2.2, 2.4,2.7, 3 or even a 3.2 6 cyl? If I figure a 914 weights in at 2200lb, I am thinking I will need 150hp to get at least a similar weight to hp advantage.

Also, about how fast can be achieved per gear relative to these cars?
One more question... in the 6 conversions, what it could be expected in 0-60 times? (IMG:style_emoticons/default/driving.gif)

That "feel" is what metters most... What the feel is comprised of it torque more than anything else and this is where the TIV shines above most every other engine IMHO. If you look at power ratings and dyno charts from other 4 cylinders and even some sixes you won't find the low down torque and midrange torque that the TIV prooduces being paralleled very often- even with modern engines.

My entire program has been based on ffectiveness, this comes from engine recipes that are very efficient and promote mixture quality and that enhances drivability while creating a very usable powerband.

It has been my goal to create engine packages that when coupled to proper gearing offer a powerband that can be fully experienced EVERY TIME the car is driven, whether this is a trip to the gas station or on the track. The power band of a six or other higher peak HP engines that are similar can't be used every time the car is driven unless you like to hit redline continually and that gets old.

Most of my engines don't need more than 6,000 RPM to make all their power and thats something that can be compared on paper because dyno charts don't measure acceleration.

But here is a good example of what a MassIVe engine can do when being shifted at only 5,500 RPM.

The experience that Cone Dodger is having is what can be expected when a vehicle stays on a diet in the engine bay, retaining its nimble characteristics while effectively doubling the stock HP..

And it only took me a 10% displacement increase to create a 100% increase in power output.. Don't think I have ever seen that from a six on pump gas-
