Any Dyno Graphs for a Fully Stock L61 2.2?

Wondering what the Torque/HP graph looks like for a stock 2.2 engine, like the one in my '05 base coupe.

Yeah that doesn't surprise me at all, but is there a graph available so I can see the power band?

145chp @ 5600 rpm & 155ctq @ 4000 rpm from the factory. Give it about 10%~ loss for power at the wheels and that should paint a pretty good picture. Hope that helps some.

Probably the best you'll get.

Haven't found a stock or tuned LAP dyno though :( Think it's closer to the 2.4 but moved down a bit

I wish I could believe those graphs. The only thing I'll go for is the complete lack of torque at 1400 rpms compared to stock on the L61.

I think my car is a dog until 2000 rpm. Which kind of sucks when I'm trying to zip across traffic real quick

Yep, the more airflow dependent bolt-ons you have, the more gutless your car will be at lower rpms. I've got a CAI and a headerback. She's a limp noodle below 4k lol

Once I get the LSJ TB and 2.4 IM bolted together, I'm going for a tune. Hope that can get her to hustle a bit.

Thanks Andrew, that was pretty much what I was looking for! Just wanted to see the shape of the graph to see how soon peak hp/torque came and what the range was.
