3.6 engine dyno pull, results for those interested Options

[nine14cats]

Here is the engine dyno pull for my 1995 3.6 993 pre-vario ram motor currently inside Fritz. SirAndy has the exact same motor configuration that I sold to him. (I had 2 3.6 engines for a few weeks!)

Motor has stock ECU, with the stock air filter and box cut to allow more air flow. 1 3/4 inch headers with Phase 9's. No AC or PS pump. 100 Octane gas.

It is interesting to note that this motor was $7500 delivered to my door 2 years ago with 34K miles on it. I sold the 993 exhaust, the upper assorted hoses and engine tin for $700. The headers were ~$550, so I came in at 7350.

The dyno was performed by Jerry Woods and the figures have been corrected for altitude and humidity and whatever else is corrected:

RPM HP TQ
--------- ---------- ----------
2500 87.1 182.9
3000 112.4 196.7
3500 137.7 206.6
4000 172.2 226.0
4500 208.6 243.4
5000 246.1 258.4
5500 264.3 252.3
6000 287.6 251.7
6500 282.6 228.2

Pretty awesome torque curve. And you can feel it. Right now I have a shift light set at 6K. I remember Brad saying the shift point for acceleration is about 500 RPM past peak Torque....which makes my shift point between 5500 and 6000 RPM. Factory red line for the motor is 6800 RPM I believe.

SirAndy,

This is a good basis for you to start with your chip mods and air intake mods. 300+HP with a chip seems attainable. The headers used for this dyno pull are the ones I sold you.

If we didn't have to use a 915 box, this -6 conversion swap makes alot of sense. 288HP out of a non-stressed motor with hydraulic valves.

Nice! (IMG:http://www.914world.com/bbs2/html/emoticons/beer.gif)
