Absolutely love seeing more VB content!❤

I live in south FL, it gets super hot in the sunmer. I went to ets tmic and it makes a huge difference in having consistent power.

[Anthony-pnjx]

Love the format of real world testing a few different options. I’m still rocking my big turbo focus st and 95% of what I’ve done to the car was due to videos you’ll put out about that platform. These videos are extremely helpful to let folks make the best informed decision on their upgrade paths. Also, I’m very interested in more Explorer ST videos. My wife has been eyeballing picking one up so I would love to see more videos on those.

It seems the design of the Perrin gives it a slight advantage. Great test!

[jedwin]

Interesting test. Also thanks for discussing the size differences as I have a strut tower brace and I wouldn't want to buy one of these and have it interfere. It's the STI brace and it's already a tight fit with the OE intercooler.

AMS tmic is pretty big too, ask me how i know.. great test video

[chefrizla]

Great video. I’ve been debating on what one to get. On a side note I installed the larger hood scoop and it’s dropped temp 2-3 degrees at highway cruising speeds according to my access port

[tenzoo]

Awesome info, really wish you had an AMS version to test. I'm leaning towards that one right now

[IanVB]

Awesome video!! Still debating on upgraded top or front mount -
Video maybe??

[brianspeed]

The process west top mount has 2 inlets into the intercooler, that would be interesting to see. It is only other option besides Perrin that ditches oem piece.

I'm kind of thinking replacing top mount might not be worth it and just going front mount would be the way to go.

Process West has 2 front mount versions, 1 of which retains stock crash bar. The ETS and Mishimoto have aftermarket bars.

[luisrosario]

Great Video! I wonder if the COBB shroud provides any benefits.

[ironmandingo]

will you do a seperate segment for vb front mount intercoolers? also when is it time to go front mount on the vb? i have the ets top mount and make 380whp and 470 ft lbs and the car feels amazing

[igortodorovic]

i understand it wasn't tested in this video. I'm not sure if you've done any research on it. Does the Mishimoto intercooler compare same as the others in this video? I'd be guessing yes but I'd love to hear it from you since you've done way more testing then i would.

[AnguishoftheDAMND]

I may have missed it- I have a new 2024 tR and I am not going to be tracking it yet or anything like that- it’s pretty much a weekend car at this point. What other mods are on the car and from what I can tell a Cobb OTS 93 Tune with a good Intake should get me to 330ish wheel HP?

[tmanrogers]

Hey brother is there anyway you can test the mishimoto top mount

[brandonclayton]

I wonder how the process West tmic compares?

[racer]

When will the VB get a true burble tune?

[italanstallion]

I love how these products are $700+, but yield little to no power differences. This is why I skipped it, and just went intake. Not worth it in my opinion. thanks for the cool video!
