3.3TT DIY intakes w/Heat shielding drop about 0.2sec off 0-60

Hey guys. Granted I’m new to the forum but your intercooler should do all the work for cooling. Even if you get cool air from the filter the air gets immediately hot by the turbo. Both my other turbo cars highly modified don’t use any block off plate. Granted both are away from the engine bay and right behind the headlight helps a little but my intercoolers do all the work

Yeah, the intercooler does a lot, but you can help it out by keeping temps down pre-turbo. At around 15 psi of boost you are basically doubling the temperature before going into the intercooler(not including any heat picked up from the hot turbos). So in that example for every degree you save pre-turbo you are saving at least 2 degrees post-turbo. At least on the stinger's stock intercooler I think inlet air temps are worth paying attention to.

Agreed it can help. Would be nice to see dyno numbers on the with shield and without on stock ic. I’m sure on a upgraded ic probably doesn’t do as such

I don't think dyno numbers would be very representative of real world performance comparison for heat shields. Maybe track times with datalog would be better.

Is anyone from this thread who started with diy intakes still gunning them? Any dyno updates?

if anyone in Canada is interested in the DIY intake, I have mine for sell ! got the filters, 90 degrees elbow and heatshield !

What happened that you are changing up your air intake ?? Just wondering

What are you thinking for a price? I can buy the whole thing for $100 so I’m kind of leaning that way

hey Arnie !
someone traded in their car and didnt get another Stinger so they had their K&N intake up for grabs.
if this hadnt come up and was not free, I would have kept the DIY intake , they are much more aggressive looking than the K&n set up

Just Pmed you !

Smart, at least he might get a bit cash back if he can sell it , not much more I can do to mine for basic Mods , but I really liked having CAI which uses the K&N air filters

I have my DIY intake and heatshields for sale too, lol. Moreso for those on the west coast (Edmonton). I think it would be expensive to ship, so better for pickup.

With that said I have not been pushing to sell these due to Covid and human interaction.

 

[runner1]

Why did you change?

 

[Revvdmedia]

Why did you change?

Traded the Stinger in. Would have kept running them otherwise. They made fun whooshes.

Thanks for all the great tips guys! I did my DIY intakes using @StungBlueGT2 mounting advice.

I figured I would join the DIY intake party. I haven’t come up with a heat shield solution yet but I have an interesting alternative I’m going to try.

The first image is my first bracket attempt.


My first bracket version using the supplied pieces of aluminum in the air filter.it worked ok but was wobbly.


My second version of the bracket using 3” angle bracket from Ace hardware (bent half way down one 3” side).


This one worked well. The bracket is zip tied to the elbow.


And the final product. Heat shields will be coming.

 

[wittmason]

The next version I’m going to try takes inspiration from the Johnny Tig setup and what @Hyperjetta did.

Here it is roughed in.
Before you comment on them not being connected I KNOW! It’s a WIP still. The cool parts are we reuse the stock box for heat shielding and the filter actually fits inside it (because of how it’s oriented). The filter is actually the same shape when turned 180 degrees from the other things folks have tried. You only need one extra elbow per side and a coupler.

This one has some potential I think.





Also a big shout out to @StungBlueGT2 for inspiring us all to create something inexpensive but performant.

All innovative ideas guys. I still think the most effective way to mount these is like this. You don’t need brackets when you point them down and use the Spectre heat shields and I’m not convinced the lower portion of the stock air box is of much benefit.

Mine are also mounted down like this. I secure them with a few zip ties to the cross beams.

Did you sneak into my garage and take pictures of my car with almost exactly that setup?

I made a video of my cheap intake install if anyone wants more details.
