Horsepower for all the (common) Porsche engine options Options

[Tdskip]

Seems like a useful thing to have summarized somewhere. While you can build just about auybof these to be a monster compared to stock, how about if we list stock values for now as one reference point?

1.7 flat 4 - 79
1.8 flat 4 - 84
2.0 flat 4 - 99
2.0 flat 6 - 109
2.2 flat 6 -
2.4 flat 6 -
2.7 flat 6 - 150-200
3.0 flat 6 -
3.2 flat 6 - 213-240
3.6 flat 6 - 275-300

Look like the right list?

Sort of. Engine power varied by year and spec. For example, a 914-6 was about 110hp but a 69-911S was about 180-190hp. Both 2.0 engines. Even US vs ROW could vary 10-20 hp.

My '87 3.2 was 217 stock I believe. I believe with the 964 cams, Steve Wong chip and Ben's full exhaust I should be at 240. At least that is what I am told. (IMG:style_emoticons/default/beerchug.gif)

I'd say my 2.4 S spec 7R cased, Solex cam'd, Weber carb'd, Clewett ignition'd engine is turning about 175 HP?

MSDS headers, GT muffler, ported heads with big valves. My car scoots.

I could be wrong +/- a bit, but that's how it feels.

It's guessing game until you dyno your car's motor.

Show and tell:

My stock euro 3.2 is supposed to put out 231 hp with stock exhaust and catalytic converter. My car has no cat, but also has Steve Wong chip, MB heat exchangers and muffler. So at least 240 hp.

(IMG:style_emoticons/default/agree.gif) Plus, later model cars had more emission controls that reduced hp a bit.

My 2.7 Henry Schmidt built engine (RS P/C, S cams, Weber’s) dyno’d at 199.5 at the rear wheels. The torque advantages of the larger engines are nice however.

[jfort]

My 2.7 by Jay Kjoller dyno’d at 197 at the wheels. JE Pistons, Solex cam, DFI twin spark, PMO’s. The sound and the power are intoxicating

[Tdskip]

Those sound like especially healthy 2.7 builds gentlemen.

[GeorgeRud]

It’s a very nice choice for a -6 conversion without the DME complications of the 3.2 or 3.6. A carbed 3.0 SC motor would be great as well once you replace the pistons and cams with ones that are not so limiting (and also replace any Dilivar studs).

[ConeDodger]

Supposed to be 207HP US Spec 3.2. Marty’s headers, no Cat, K&N, I’d guess 225HP?

[SirAndy]

Stock 3.6L aircooled, naturally aspirated, HP range from 272 - 285

With headers, Steve Wong chip and some other minor improvements you can get in the 305 range.

Mine is similar. 964 cams, euro compression, slightly stiffer springs to rev to 7K and a custom SW chip to run on 93 was dynoed at 244 by the PO.
Next engine will be 3.4 with Sal's custom MAF, injectors and chip to hopefully get to 280. A early 915 trans with 7:31 ring and pinion for a quick getaway. (IMG:style_emoticons/default/happy11.gif)

Those cars must MOVE.

How about 2.2, 2.4 and 3.0?

I think 2.2 was around 125, and 2.4 about 140? 3.0 around 175-220?

1.7 flat 4 - 79
1.8 flat 4 - 84
2.0 flat 4 - 99
2.0 flat 6 - 109
2.2 flat 6 - 130, 155, 180 (T, E and S)
2.4 flat 6 - 140, 165, 190 (T, E and S)
2.7 flat 6 - 150-200 210, 230-245 2.7MFI 8.5:1 and 2.7MFI hi comp
3.0 flat 6 - 180 - 204hp
3.2 flat 6 - 213-240
3.6 flat 6 - 275-300

All of the hp's above can be improved upon if you stray away from factory setups/specs.

I'm getting 230hp out of a factory spec 2.7MFI with a great space cam and 310hp out of a 3.6Vram motor (ECU'd, sport cams) on a couple of my cars.

[mb911]

Larmo is likely a little light on hp numbers for his 2.4 setup and is exactly the same as mine.. Henry from supertec expected mine to be about 200.. And that is for a 2.4..

Great discussion gentlemen, good to have this all in one place.

I think the next interesting thing to collectively have a chat about is the crossover point on horsepower versus cost building out a more powerful flat four versus swapping in a six.

I know that’s apples versus oranges and how the car feels, but I think it would still be useful.

For example, total cost to build 130 hp flat for versus total cost to get that same horsepower with a flat six.

[Marv's3.6six]

My engine builder estimated HP for my 3.6 @ 320-325 engine is a 95 993 ROW engine (Canada) Cylinder heads massaged & milled to increase compression 1/2 point to 11.7 to 1. WebCam RS cams for 993 with hydraulic lifters. Fuel injectors blueprinted & match flowed. Patrick Motorsports intake & filter. MSDS 1 3/4" headers. B&B loud ass muffler. Steve Wong custom 993 chip. 7000 rpm red line. 11 lb flywheel. Yada yada.
