If you look on his Car Domain page it says 166 HP.

 

Thank you detective Howdy! So much for disclosure, huh, So-Cal . No what is your G-tech saying you are putting down. You took a picture of it with the other functions, why not hp and torque??

 

That was the G-Tech result. Sorry I didn't clarify. There is no mention of the dyno numbers, but there is a HP shot of the G-Tech. The one thing I worry about from that shot is if the G-Tech is fairly accurate (which I believe it is even though I trust a dynos numbers more) and Chevy's power rating of 172 HP is also fairly accurate then it looks like you lost 6 HP by changing the muffler. The G-Tech is still a valuable tool if you don't want to take a trip to the dyno shop for every small mod. The dyno can't tell you things like how many Gs you are pulling on a skidpad also. Of course track results are track results - undisputed. Like snksknr94 said the only way you are going to get the true 1/4 mile time is to go to the track.

 

Your demoted back to captain, no more detective for you.

 

Ummm....Captain - you're forgetting something; the 172hp number is GM's "engine" horsepower. My G-Tech reading is actual at-the-wheels horsepower - which should be a considerable increase over stock (you're going to lose way more than 6hp to the wheels).

Nice try though - detective!

 

I keep forgetting that. It's been on of those days.

 

No problem.

 

Well, I can tell you what my dyno sheet from K&N says. My 2.4L puts out 144.22 hp on their dyno. It was run yesterday morning before the intake test. I do not know what the numbers are with the intake. They are still developing it.

Just an FYI if you are interested in the actual readings completely stock :)

It would be productive if it was mentioned the brand of the dyno when quoting dyno results. As I've posted before, different brands offer up different readings which can have deltas of around 5%.

 

I am sorry I forgot to include that, it was a Dynojet dyno. I was going to put that in my post because I knew it makes a difference. I wasn't sure if anyone was even interested in the before results since I do not have after results. Also the test was done in second gear according to the report.
