3.2 & 3.6 HP/Torque Curves

[patkeefe]

Anyone know where I can find HP/Torque curves for the (typical trim) 3.2 and 3.6 engines? I can't seem to find them in the usual search locations.
Thanks!

Thanks!

Your welcome. Hope it helps.
This I still find amazing.

Here is some more subjective and hard data for you......
The numbers are the actual rear wheel hP and measured weights posted here on Pelican (BBII) or from our local Dynojet except for the Ferrari Stardale. One lesson? Drop weight and add HP!
But not the only lesson.


3.0 liter '79 2625# 183 rwhp 14.34 lb/hp


BBII 2400lbs and 243hp 9.88 lb/hp


3.4 CIS 2200# 223 rwhp 9.86 lb/hp


996 TT has 383hp and 3515lbs 9.17 lbs/hp


ZO6 our dyno 350rwhp, 3100lbs 8.85 lb/hp


Craig's 3.6 weight 2455# 280 rwhp 8.76 lb/hp


GT3 on our dyno 368rwhp 3043# 8.26 lb/hp


Alex's '72 has 268rwhp and 2100lbs 7.83 lb/hp


Stradale 3000#s and 392hp 7.65 lb/hp

Thanks again, Dane. I had the opportunity to get my 78 SC on a chassis dyno today (shameless plug for PowerTech, who had their chassis dyno at Pocono this weekend). I have been curious exactly how underpowered, by current standards, my little pig is.

These tests came back surprisingly well, showing a HP of 161.4 for my 2650 lb car, equating to 16.42 lb/HP. This is a bone stock 3.0 SC engine, with over 166k miles on it. I didn't think it even had that much power.

I'm still trying to finalize my rebuild options for the winter project, and thought it woul be handy to see some of the HP and torque curves, and examine the bands, to get an idea of which direction to head in.

Attached are the curves for everyone's amusement!

Not many cars out there that are as much fun as a well tuned 3.0l SC.

SSIs and a sport muffler will really wake it up as will a 20/21 or 964 cam. I have wished many times that I would have stopped there

Pat, does the fact that you are looking for 3.6 curves imply that you are considering a 3.6?

[Jack Olsen]

It's useless to compare different dynos/operators/setups, but you can get something out of comparing the shapes of the torque curves.

Here's a 3.6 with a chip and exhaust.

I agree, Jack. Examination of the curves is the key element in making a determination of where I want to go with this project. The 3.6 curve you posted is very similar to mine in its slope and effective power range, but the curve is transposed up by 70 HP or so...it's just a lot more power.

And, yes, John, I'm considering going to a 3.2 or 3.6. Although my SC can run pretty hard, I am just way underpowered.
