As you all know, I recently purchased and had installed a Fast Intentions catback system and high flow cats on my car (G37s 6MT)

I went to Church Automotive in Wilmington, CA today to have it dyno'd and see if there were any gains. They did 3 runs total.

Here's the video:

Here's the results, compared to my stock #s. Keep in mind, these are the peak hp/tq numbers, and not the highest gain along the powerband.





Peak horsepower:
320.4 hp @ 6700rpm

Peak torque:
265.6 ft/lbs @ 4500rpm

Here's highest gain (not the peak numbers) along the powerband:



Highest horsepower gain of
18.2 hp @ 6700rpm

Highest torque gain of
13.2 ft/lbs @ 6600rpm

Decent gains imho

I'm VERY happy with these mods

Thanks to Tony and everyone else at Fast Intentions!

Make sure to scan the sheet they should of gave you and add it to the dyno thread that we have in the "engine" section that is stickied.

GiGGaplease

yea, like a 30 tq lost at around 1500, but they wouldnt matter anyways. numbers is good.

So you got 304hp when you dynoed it in stock condition? or am I reading too fast?

What kind of dyno were you on? Those numbers sound veeeeery generous...

^^ The type of dyno doesn't matter. What matters is it was done on the same one, therefore he picked up that amount of power regardless of how you look at it.

KCMO

yup, don't look at total numbers, look at the gains made between old and new.

Very nice improvement though. I'd love to see what a reflash and the fabled injen intake does.

So that is flywheel power not whp? If you only got 17 at the flywheel you loose about 18-20% to the wheel so that would mean only about 14 to the wheel. Better than nothing but still not huge. Unless I am reading this wrong.
