Lower intake

avery370z · 09-20-2014, 01:56 PM

Below are the numbers before and after.

Megan370z · 09-20-2014, 04:13 PM

Thank you

so with stillen headers and your lower intake porting gained 20whp
there is quite a nice jump starting at 6800 to 7500rpm ( that's where the VVEL jump at his max)

there is a steady 2-6whp gain from 2600 to 6000rpm then start to open up 10whp gain at 6800. Then end up with a 20whp gain at peak.

Not bad, I wonder how much of gain is related to the porting.

the problem is i don't know how much porting that company removed from the lower intake .. hehe

because I do have an extra one here and I did wanted to do something similar but its quite low in my priority list.

I never thought I would ditch the N/A world. It seem like the dark force was too much to resist !!!!

just saying i would gladly throw one on and test it without and other mod addition.

im still on the same set-up from when i got tuned about a year and a half ago so i should be close to the same numbers.....i'd hope lol

Why not run it same day though, then install, and run again? To save time show up with the brace off and do the coolant line delete on the TB's so all you have to do is disconnect the CAI, pull the 8 bolts to the lower from the upper, disconnect one fuel line, and pull the lower. Its pretty easy to do. You hate me but I'd still have the lower ported and shipped direct to you from Shawn at Synergy Composites. He's my new porter I have all the details worked out with and we are ready to start doing this for everyone with my ported TB's I have done which I also have a deal worked out with from Maxbore.

it sounds like a fun possibility but i'm currently house shopping so my mod funds are technically on hold.

hence why i said someone send me the stuff i'll test it lol not buy the stuff

soon i should be able to start buying parts again.

Was the temperature similar for the before and after dynos?

avery370z · 09-20-2014, 09:50 PM

From just the extrude honing I don't know but I definitely felt the difference with my butt dyno. Next are the heads and I will post whether it makes power or not. Ptuning s dyno is in an environmental controlled room so the conditions are pretty much the same. I'm just exploring how much power this NA motor can make.

Eclipz · 09-20-2014, 10:22 PM

what do you plan on doing to the heads? Can you please list the other mods that you have? thanks and good luck with your plans

avery370z · 09-21-2014, 12:44 PM

I'm disassembling my heads and going to Extrude Hone them and get a three angle valve job and slap them back on and see what happens. I would like to thank Jon @ Z1 motorsports and Patrick from Ptuning without there help I couldn't make this project work. I will create a sig that list all of my mods.

Hmmmm so I guess I was right in believing him this whole time!

Maybe, maybe not. How much recalibration done with the dyno months or weeks apart? Tuner mess with any settings within the computer of the dyno? I'd still like to see temps and such. Also what's the correction factor setting? These numbers could be the difference of SAE to STD or SAE to STP. Lotta lotta variables here. Like Megan said. ONLY!!!!! Way is same day, same dyno, no touching.

avery370z · 09-22-2014, 12:54 PM

Well guys all I can say is there's some room for this motor to make some more power. Everything is trial and error. But the end result is we are all trying to see some hp gains. Have fun doing it.
