[Bulkybear]

Honestly if you want a good intake for our cars. Go with a ct engineering supercharger lol.

I was thinking about this

And boring the stock IM to match the TB.

I'm gonna have a hard time selling my RBC now...

+1 Squiggy. That's no slouch of a dyno

Maybe not. One tuning vendor has stricken fear in the herd because of midrange. I don't care much about midrange, except in my Celestion Greenbacks.
Midrange dip doesn't mean that's the end of the story, does it Axion? You have great numbers posted in the dyno above. Right? I'm sure there are people out there who loved their RBC conversions. Right? Anyone?

 

[kennyjames]

what mods does the axiom industry dynno chart have? those are extremely decent numbers

 

[hotdogjohnny]

^^^You're asking them, right?

 

[kennyjames]

well im assuming someone here as the info haha

 

[webby]

squiggy tagged them in a post above, so we'll see what their mod list consists of on that run

As promised, I received my OEM parts back from Maxbore today.

OEM Throttle Body Bored to 68mm tapered with new butterfly.



P2R Throttle Body Spacer/Gasket Bored to Match new Throttle Body



Intake Runners (Fuel Injector Base) w/P2R Thermal Intake Manifold Gasket. Stock casting marks removed with 2mm port job. Pictures don't do it justice.

I also have the stock "plastic" Intake Manifold ported to match the new larger throttle body as well. I can try and take a picture of it as well if anyone's interested.

 

[hotdogjohnny]

really nice work on a great idea.

 

[Stealth]

I appreciate it. I'm anxious to see what kind of final numbers I can pull with it added to my current setup.

 

[323]

My parts are looking good!

 

[Stealth]

Thanks Josh. I'm glad you talked me into the idea.

 

[kennyjames]

hey @Stealth im assuminfg that piece with the gasket is the P2R adapter piece?

 

[Stealth]

That's right. That's the P2R Throttle Body Spacer + P2R Throttle Body Gasket

That was on Vits E dyno.... We dynoed on E85 and average around 50whp over stock Naturally

We were hoping you could provide some insight (or counterpoints to Vit's observations) on the effectiveness of the RBC itself as far as NA tuning in relation to the power and torque curve.

More input about the loss of midrange torque would really help this thread.
