Fiberglass heat shield...

[nate23232323]

Ok after a hot day of driving with my SRI i see alot of bogging wen take off... so i read up a bit and saw that people are using heat shields in the engine bay surrounding the intake. im thinking of fabricating a heat shield and a path from the front grill area to the SRI. Of course wut im trying to achieve is block heat from the engine and "Ram" air thru to the intake. Any pros and cons that anyone could point out before i waste time and money...

You could.. use your life..
Ahh I actually heard good things about heat shielding a SRI. I was actually considering doing this as well. Though I really doubt it'll be like any authentic ram air.

pm jlitman he as a link for heat resistant material to use

[nate23232323]

well the fiberglass would be more of a costum form and would be coated with heat resistant material.... thanks "trd" :)

Just want to know, is it ok to run a SRI without the heat shield?

Just want to know, is it ok to run a SRI without the heat shield?

is that a serious question?

[trdmsprts27]

yes you can run without the heat shield, the heat shield will block a small portion of the heat given off of the engine and radiator

[Jadakiss2127]

is that a serious question?

Ya it is, wanted to know what the heat shield really does, and he just answered me. Sorry i wanted to learn something i didn't know.

[nate23232323]

ok all good just making sure... the reason im tryna just go with heat shield instead of just getting cai is for one i live in wa and mostly it rains and two because i already have sri and might as well just build to that

If you can completely seal off the engine bay heat, an SRI has the potential to have the same peak whp as a CAI. But only at peak. A CAI will still easily win at low end.

I would think the SRI would win at all around if it completely sealed away all engine heat and drew in air from the outside due to shorter tubing. I kind of thought of a design that put the filter in a box that drew in air in front of the radiator by a scoop.

Bro I live in Oregon... If you install the Cold air intake correctly you will be fine. I did mine 2 years ago and still going strong with how wet it is here.

I kind of thought of a design that put the filter in a box that drew in air in front of the radiator by a scoop.Piping length also has a role in power. Just like the exhaust, the intake has pulses, and getting the right length to optimize those pulses is critical for power. That's why an AEM CAI destroys an Injen CAI on low end power on a 2ZZ, and only loses out by 1-2hp up top. They're both long pipes, and the AEM even has more bends, but the AEM's length is better optimized.

That is weird, always thought shorter length of piping would benefit power even more, and if you sealed away ALL engine heat for the SRI then it'll outperform a CAI, due to its length.

Someone dynoed a fully sealed off SRI, and it had good high end power just like a CAI, but very minimal gains down low compared to AEM's CAI.

i made a fiberglass heat shield for my sri
when i made it i put a 2in hole in the bottom of the sheild and ran heat duct foil piping through to the inner fender well
i got that idea from some kid on the site
mines a lot nicer and has 2 filters on it
i can hear the difference and slightly feel it
my friends integgy would keep up nose to nose
but now i have a little bit of an upper hand on him and pull off
i was surprised at the difference
it just shows how bad the heat soak is with the sri
i would suggest trying if it dosent work all youll lose is some fiberglass mat and resin

so the AEM CAI is better than Injen's CAI?

[Blue Bomber]

If you look at more of the dyno than just the peak power, easily. At top end, Injen is 1-2whp better. AEM gains a ton of low end power, where Injen gains nothing (it's also more prone to bogging, which loses low end power). AEM has a much larger impact on overall power where variances from one run to the next (like 1-2whp) don't come into play.

cool thanks for the info
