2007 2.4 sc results..???
Wondering if this seems high,
dyno tuned my cobalt 2.4 sc and the numbers were higher than expected
mods: stage 2 73.0 pulley, 60lb injectors, intake, exhaust, dp, flywheel, dual pass, option b, zzp heat exchange.


Oem slipping clutch @9lb tune isn't done yet

Nice numbers.

I wonder if that 73mm pulley is one of my old test pulleys I sold back in the day.

Seems right, for that pulley setup on the larger displacement. They make good power until they break something in the bottom end.

Oh yeah, with a good tune I wouldn't be afraid of 300whp on a 2.4, maybe more on a turbo car. But it's getting close to questionable at that point.

Would that be considered 2.9 or 2.8?

73mm/(25.4mm per inch)=2.874" pulley

There are people running more than that no issue. I'd say I am probably a bit more than that. Torque ain't that high though

Do you not know how to math? I gave you the most exact answer possible. Just call it a 73mm...

Yes, it's not hard to do. You will need a 2.5 BAR bosch MAP/IAT2 sensor part number 90423637. Heres the wiring diagram:

You will probably need this connector too: 2.5 Bar Pigtail (Part #88988320) Home » Shop » Connectors / Harnesses » Bosch » 4-way sealed Plug Bosch BSK Connector Kit for Bosch MAP Sensor
Overall you cut the IAT1 wire from the MAF sensor and connect it to the IAT2 terminal on the connector and your ECM will read your IAT2 temp as IAT1.

Where would this be going in the manifold?
