As soon as PPE comes through with that exhaust I ordered...MAPECU3 will be next install

 

Looks like my exhaust is being completed this week and just needs to be sent for coating...I already have next week scheduled for install and dyno time. I will post many pics of the exhaust and try to get some exhaust sound clips up.

 

Hope all goes well! Hoping for great results!

 

So, have you got dyno numbers on this yet? Or is there something holding you up? Life maybe?

 

Dont Jynx it Scott... Everytime someone does an Awesome build, something always happens before a major update. lol.

 

Here some pics of the exhaust (2.5" pipe) all I can say build quality was top notch, guys at the shop were impressed with the quality of the build and perfect fit of the exhaust, also everyone liked how it sounded couldn't be happier with PPE exhaust!!

 

I had it on the dyno but results are incomplete at 4500 rpm boost dropped off for 4 psi to 1 psi next week going fix and maybe have some dyno results to post... but ill post what I got i hit 319 whp and 350 tq before boost dropped... Shop said it looked like car would put down 400 tq if boost didn't drop. I had some video to post of my car on the dyno but phone didn't save it ill post some next go on the dyno..

 

Get an extra bung welded in for a wideband! Those "sniffer" exhaust readers are inaccurate.

Sounds like a typical boost-leak somewhere. Once you get that figured out, let us know what you ended up at "power-wise"!

 

Needing to install my NGK AFR monitor and Coolingmist water/meth
yea thinking it has to do with the bov need to change vacuum source and maybe play with springs

Here's the latest dyno run over lapped the previous dyno run right after I had PPE headers installed I had more boost before something is not right??

 

That's quite the boost drop for a spring issue; sounds like a "major" boost leak. Are your pipes bead-rolled with T-bolt clamps? New components or used?

Where is your current vacuum source? I pulled my engine cover today and played around with this port on the intake manifold. Perhaps a good source? IDK.

 

The pipes are not bead-rolled I have t-bolt clamps. From the pic you posted the area you circled is exactly where my vacuum line is currently routed to. I’m going tap a new vacuum port right after the throttle body as recommend by another member with more experience in supercharging the IS.

 

Do the DIY hair-spray trick on the piping then; I've only ever used bead-rolled I/C piping...never had a boost leak. The one component that wasn't bead-rolled on my Honda (the TB) managed to pop off during dyno tuning; scared everyone, mostly me I guess. Enough pressure that the steel piping dented the shock tower! What a relief after such a simple fix though.

 

Comparing your dyno sheets to mine, It looks like you're going to make a ton of power man. Good luck with those issues, that's the hard part!

 

Thanks..I hoping all this $$$$ pays off

 

Need some info from people who boosted there car...what plugs did you end up using?? Thinking about buying a set of the HKS plugs same as would come in there S/C kit.
