abtin90 Posted January 12, 2011 Share Posted January 12, 2011 Does anyone know what the advantages a front facing intake manifold have on an NA and NA-T? I know they would help clear up space for turbo conversions, more space between the bonnet, and would prob look a lot better (with it kind of having a tt look) but what else does it offer... And would anything else need to be relocated to install one? Also what companies sell them? thanks Quote Link to comment Share on other sites More sharing options...
JamieP Posted January 12, 2011 Share Posted January 12, 2011 Gotta be better for the intake temps than having a IC pipe run over the hot side of the turbo. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted January 12, 2011 Share Posted January 12, 2011 The air flow in feet per second through the inlet pipework is so fast under boost little conducted or convected heat will pass from the pipe walls to the air within. The surface area area V volume of gas is pretty insignificant as is the contact time. I'd be more worried about equal port air flow if you mess with intakes, they need looking at n a flow bench really, to see what's really likely to be happening.

dr_jekyll Posted January 12, 2011 Share Posted January 12, 2011 so are you reccomending to stay with the intake toyota intended chris ? this is something i have considerd but i have also heard that the stock na inlet is verry well designed and removing it could cost alot of torque. any educated advanses on these theorys?

Nic Posted January 13, 2011 Share Posted January 13, 2011 Does anyone know what the advantages a front facing intake manifold have on an NA and NA-T? On an NA no advantage, you would likely lose torque compared to the stock variable intake manifold. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted January 13, 2011 Share Posted January 13, 2011 My answer was assuming someone was turbo charging an N/A. For true performance gains keeping it as an N/A you need cams, throttle bodies, more compression, more revs, and a mappable ecu and a lot of mapping time. It will drive very differently, drink petrol and cost a fortune. 2 stock TT's would probably be cheaper than getting a lot more grunt from an N/A Quote Link to comment Share on other sites More sharing options...

steve spedd Posted January 13, 2011 Share Posted January 13, 2011 loads of boys in the US run FFIM, i guess if they are flow tested and proven to work it would be better. Depending what turbo you are running it wont fit with the stock IM. Quote Link to comment Share on other sites More sharing options...
