i dynoed my car at the HPP charity dyno event sat, and it put down 227/225... is that about par for what an 06 5at g should put down?

 

I'm trying to remember what my '04 6MT put down when it was stock ... I want to say it was around 235/225 so your numbers are about right on par.

There's a lot of variables when the dyno operator is setting up the run, they need to accurately enter the weight of the car which creates a correction factor.

Now you've got a good baseline to start doing some mods and see how much hp per dollar you can get

 

whats gonna be the best bang for the buck? ive bought an aem intake, and looking for my next mod, maybe exhaust...

 

Best bang for the buck? A cheap used supercharger or turbo

But without spending several thousand, I'd say just about the best mod for the buck is a plenum spacer. Replacing the manifold in addition to a spacer can yield significant increases in HP and TQ. Check out Motordyne's collection: http://www.motordyneengineering.com/G35.htm

 

i would love to turbo the G, my buddy who runs HPP turboed his 350 and that thing would haul some serious *****...


thanks for the link, looks like i will be ordering an manifold and spacer....

 

2003 to 2006 5ATs have the same motor. You would only need to buy the spacer. If you do the MREV manifold, you might run too lean.

The 1/2" spacer gave me 15HP and 17FT on the dyno. Check out my dyno

You really don't think the ECU would make up for the increased airflow? Or is it because the increase is already after the MAF sensor?

I'm also running the 1/2" MD spacer but results are typically different with FI.

 

Here's one of the posts that made me send back my MREV2 manifold over a year ago. I never installed the manifold.

My car runs an A/F of 15.1 just before 3300RPM. Once it goes into closed loop, it drops to 12.X. I had the dyno sheet that showed it, but it was miss placed when I moved.

 

That's some interesting stuff. However, I agree with one of the posts that there is no way that a bolt on could require you to go with larger injectors. I'm running Vortech with stock injectors...

 

If he has a 5AT then the motor is a non-revup. The MREV2 is only used on the revup engines. With the 5AT the spacer is the only thing needed. In terms of power I would do this before the exhaust.
