HelloFirstly, I would like to point out that this is not my set up, not my car, and not my claims. I'm just wondering your opinions. Recently on a forum I frequent, a guy posts pictures and dynographs of his SOHC KA24E-T making 105-114 horsepower and 400ish lb/ft torque. Now I can't make any sense of this whatsoever, I mean at all. I was hoping you all could shed some light on it.

As far as I can tell his modifications are: Stock internals, 550cc Injectors, 255lph Walboro fuel pump, hand made manifold, Turbo from a dodge 3500 turbo diesel, no intercooler, stock MAF, CAI, manual boost controller set on 8 pounds.

Here and here are threads he created referencing his results.

And the graph

Apparently it (the actually dyno run) was done in third gear, which I'm pretty sure will mess results up quite a bit. This was done at a local dealership that does have a very good reputation for their dynoing. Apparently he used third gear because "As Per Dyno Set up for a Torque Monster Desiel."

Please tell me I'm not the only one who sees this is not possible? Thanks.

LOL not this again. Threads similar to this have been posted on NICO and other reputable forums like Ka-t dot ORG. Both threads were smashed into the ground like both of those threads were....obvioulsy no one ever came back with HARD evidence. Case closed. PLease close this thread.

Of course its possible. A guy I know made 23hp and 1280 lb-ft of torque on his E42AK.

He was running one of these turbos.

Looks like it is the actual measured wheel torque. Most dyno sheets are corrected for engine torque.

That looks like what might happen if you did the pull all in 1st gear.

The speeds would suggest 2nd gear to me, but appears too low in torque to be second gear. Unless his motor is in terrible shape, but the 113 HP suggests he's not doing terribly. Not sure what to make of it as the torque figures suggests he would be in 5th gear. Strange.

1st gear should put a stock 240sx over 2,000 lb-ft calculated wheel torque (maybe slightly lower than 2,000 for a SOHC KA).

Needs to go to a real dyno and do a 4th gear pull

This guy posted in KA forum. When we asked him for a copy of the dyno sheet, he stopped showing up.

The best I can think is that they didn't do the correction setup or the speedo setup before they ran the test.

That is a Mustang Dyno chart. Mustang dynos are inertia dynos (meaning they measure HP and calculate TQ) TQ is calculated using engine RPM. If the dyno was not setup correctly to measure actual engine RPM, the TQ on the dyno graph will be off.

This dyno chart shows the correct HP but TQ is WAY off
