Fact finding - - Engine Spec's - - HP/torque, What HP/torque can be expected for a given engine size??? Options

[nine14_6]

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)

I have been driving my Raby kit 2270 quite a lot lately. There are some pretty amazing things about this motor. One of them is how it causes guys with sixes to go wow! Yes you can wind this thing up to just over 7K but the cool thing is the car is much more driveable. I can be on the freeway doing 75 in 5th and I have so much torque that I don't even downshift to pass. Just a little bit more loud pedal. I would have thought that my HP was around 170 or so but a local engine builder says he thinks it feels like a 200HP at the crank motor. He expects that we will see 170 at the wheels when we take it to the dyno after I finish break in.

I don't quite know how to respond to the sound thing. I have two other Porsches, both with sixes. I love the sound but I love the sound of the 2270 less that Dellorto whistle. (Jake did you send that gasket yet?)
My 2270 feels very nimble and precise. The Bumblebee six feels very powerful and brutish. Both get the job done but in different ways. Personally, I like precise.. YMMV

Taking this a step further, I was thinking about this after my first post. I have not driven a massIVe motor car or a 3.2L six, but bear with me here...

there is also a feel issue with different engines, which is what I believe CondDodger is saying as well. So, for an example I have personal experience with, I have built well over 500 V8 engines from "mild to wild". So when I built my engine for my car, I wanted VISCERAL. I wanted to hit the key and feel the engine jump up, grab me by the throat and slam me back in the seat. So I built a crazy destroked 400 Chevy with a monster cam and so forth to make 525HP. That said, I could have also built a 434 cube small block and made 525HP with a hyd tappet cam. Both would be just as fast, but the 434 with the hydraulic cam wouldn't jump up and grab me by the throat. It would punch me in the chest (IMG:style_emoticons/default/biggrin.gif) but seriously, I hope you get what I mean.

And trust me, a lot of guys asked me why I would have such a crazy engine to make 525HP when I could have built one "tamer" and had the same power. It is all just preference.

So some guys will prefer the 4 and argue all day why it is better cuz they like the more visceral feel of it. Others want a "tamer" feel, so they will go with a mild six for the same power and acceleration.

For a street car, I would put the biggest 6 in there I could with modern f.i. and so forth and enjoy a smooth, fast car. And absolutely nothing against Jake or his engines, he clearly has a solid type 4 program, I just like lots of power. So for the street I like lots of smooth power. If I were only going for 200HP, I would honestly go with a built 4 to get "feel" and keep the weight down. But in reality, if I were going to go 4 or 6, I would go biggest, gnarliest 6 I could and get the 330HP.

'Course, keep in mind, I went with a 525HP V8 for "feel" hahahaha (IMG:style_emoticons/default/aktion035.gif) I am already thinking of selling my car to build an AWD 70 Mustang with a toned down Pro Stock motor around 850HP with around 700 ft-lbs... I have too many ideas and unfortunately wish I were born rich instead of so damn good looking (IMG:style_emoticons/default/w00t.gif)
