Painted 348 intake plennum

.................... looks very 'goth'...........................

 

I gotta say, I'm not a big fan of painted ones either but that looks very good!

 

What Daniel said!

Paint the cam covers black too and it will look pretty cool in there!

 

I do like the paint, however, these intake covers already look too small by modern standards and painting them just exaggerates this. I say leave 'em alone unless they are 355 conversions or customs like Dave's.

 

Although I'm planning to buy a 348TS, I have always been a little disappointed that the valve covers are so covered up with air lines, and especially that the intake plenums are so small. I do like the 355 plenums better.

I do think moving or messing with the air lines could affect accuracy of the air sensors, so wouldn't mess with those myself, but I have wondered what others may have done with plenums. You mention Dave's.... can someone post pics, point to a thread, etc. to show what some have done to replace the 348 intake plenums?

TIA

Heh, heh, Rick, stay tuned and we might have an option for ya. So far, Bruce aka plugzit has replaced his with 355 TBs and plenums - fine if u can find some replacements on eBay (and u can't) Then Dave aka group77racing fabricated his own versions around some Volvo MAFs and TBs. And Andy Hill just installed some custom injectors, stacks and tbs (probably a high priced alternative too). We're exploring a stock modification to keep the look but improve the flow (including a plenum spacer to make it taller - sure wish we could make 'em wider too ).

 

You can. Volumetricly it makes no difference if the enlargement is inside or outside of each TB. I'd bet money that you've only been thinking in terms of the plenum volume being exclusively inside the TB, though!

Think outside the box, er, TB!

 

a while ago but i still like it.

Was that your 348 Andy???

 

Hmm, yes you are correct. We were thinking about volume increases before the TB, however, you are still limited by the flow capacity of the TB's. We are not replacing the TB's, only boring them slightly. It does look to me that the capacity of the air filter box, MAF's and tubing is greater than the TB's even after we increase their diameter. What else can you be thinking?

 

+1......... the 348 TB has the smallest cross-sectional flow area of the entire intake tract...........

 

I really like them in black...and would have never considered it...
