Stillen Air to Air setup

TopgunZ · 07-12-2015, 12:57 PM

Sounds like that could be a tricky one. Has anyone looked into swapping the two 6 rib pulleys for 8 rib? It looks like it would fit. But then again if that would work why did some go cog?

Went with cogs for the ease and availability of changing S/C rpms. They are already run that way on the DE. You can run anywhere from a 32T-32T (1:1) to 34T-28T setup. Just have to change the idler pulley OD to make it all fit since there aren't many cog belt sizes.

Dynosty built some custom 8-rib pulleys for a Stillen S/C HR a few years ago and added a 50 shot. It's on their blog a long time ago, but it's easy to google.

I contacted ATI for a Superdampr a couple of years ago. They will custom make anything you want. I don't remember the price, but it was around $1000-$1200 for one, and $600-$800 if I could get a group buy. I was shooting for around a 6.25"-6.5" OD but gave up on the whole thing.

Did some good R&D on Sunday. Placed a massive order for all parts I think I will need and should be able to get some work done this coming weekend.

Who thinks the MAFS would work in their current location on the Y-pipe except a blow through with an air straightener right before the single inlet?

Im excited to see what happens with this.

Id put the Mafs as close to the factory position as possible.

Im dropping my car off july 21 with sasha to start on the Air to Air.

ill keep u guys posted.

I thought in a previous post you said Aug. 20th with it on the dyno by the 30th. So he will have the car next week and you might be on the dyno before August?

You are correct. Were flying in Sebz from speciality Z to do our tuning.

They're coming around the 13th of aug now instead of the 30th.

so everything got moved around on our end.

But it worked out in the end!

I think the MAFs preSCer are the majority of the problems with the Stillen kit.

TopgunZ · 07-13-2015, 04:23 PM

No. I mean using the Y-pipe as a splitter for the dual intake. I have a single outlet IC. After it comes out of the ic it goes into the engine bay on the passenger side only through the same route a CAI would and like my BP kit did since that shroud is already cut for the intake pipe. Right after going through that hole, I would mount the stillen Y-pipe and house my MAFS in there then place a pipe off each into each throttle body to the stillen mani. Basically, I could use the Y-pipe that has the maf inserts already in them instead of finding a different Y and MAF pipes. Obviously I would be taking both filters off.

Hence the "blow through". My question is... Is there enough pipe before the Y so the MAFS will get good readings? Or is that short distance from the Y of the pipe too short and cause turbulence leading to erratic readings?

jwick · 07-13-2015, 04:45 PM

Can't answer that one but why not use the intakes from the BP kit and just locate the MAFs in the factory location.

I don't think that there is room to Y it off if I use them. I might have to get creative and see though.

Shorten the passenger one and reroll the edge for the coupler. You could modify the driver or leave it as is

mikey1600 · 07-14-2015, 10:20 AM

can't wait to see what happens with the 2 builds, ready to upgrade mine!

Was just going to go the E85/upgraded impeller route, but I'll wait and see

TopgunZ · 07-14-2015, 10:51 AM

Ill be on E85 and decided I need to buy the Mortordyne ART test pipes.

EVOHUNTER · 07-14-2015, 11:11 AM

This is what I have drawn up, nothing special but gives you guys an idea!

TopgunZ · 07-14-2015, 11:18 AM

Interesting. I have a series of questions though.

Are you going for CARB approval? Why are you recircing your dump back into intake and why are you plumbing into the valve cover?

Is your Y pipe sitting vertical and you are going to have one pipe underneath the other? Looks like that would be a long split.

Why do you have the BPV/BOV after the IC? This is going to pass hot air from the SC through the IC so at a standstill, any light, and such it is going to pre-heat soak your IC, isn't it?
