No Bumper support?!?

Ok so i've done my searching on this particular topic and i've found that either you don't have it anymore or it has to be modified.

How many of you TT guys had there's removed or modified? Also, how is it modified? Not to exclude the S/C guys but i believe their IC can fit behind the support correct? What's a small enough IC that can fit behind there? Thanks for your input!

BTW - Doesn't that trigger any paranoia/OCD? Maybe it's just me.

The intercooler is way too big for the TT so u will have to remove the support bar.

i think the JWT dual intercoolers sit low enough so that you dont have to remove the support but idk

I have about 1 of the largest IC's on a G, and we retain'd the support bar (it does slightly block the IC but thats ok, haven't had an issue yet). I actually thought they left if off, but Chris informed me a while ago that they installed it back on.

I have a fairly large vertical flow IC and didn't have to modify or remove the support brace.

Found pic, and if I haven't had problems with IAT temps I'm guessing most won't.

believe my core is 24x12x3 (or its 24x12x3.5 but I'd have to check) , custom end tanks.

there are only a few kits that require that you remove it, like Greddy, GTM

IMO its not really necessary since it only protects from 5mph and under but some people think its worth keeping

some people have had customs ones made to clear the bigger IC

its not so much the size of the IC, its the placement of the charge pipes that go directly in front of the support mounting point (on like the greddy or most of the TT horizontal flow IC's). my 4" core fits behind the brace bc the charge pipes arent in the way.

Hmmm...very interesting....Thanks guys for your input and Thom000001 for the pic.

Reason i posted the questions is i'm planning to go TT HKS or custom and it doesn't come with an IC. But from what you guys have said it seems a max 4" thick core can fit behind there....

Anyone else have other thoughts? Should I totally not go with a smaller IC and opt for a bigger IC? Thanks!

Basically you want the largest IC with the least pressure drop you can fit. Pressure drop is more akin to the end-tanks. Basically, with turbo technology the way it is now, get as big a core as you can fit.
You also want to get the core mounted as far back (or as close to the radiator) as possible. This does require moving the horns and moving/making a new hangar for the airbag/crash sensor.

As an FYI as well, I run the stock front bumper.

aha i see, i always though the reason they didnt fit was cause they were too tall and thick for the bumper support to fit

thanks for the info

I have always wondered if the support bar restricts the airflow to an intercooler that big and tall? The bar basically blocks all the free flow air coming in so even with that tall of an intercooler I don't really think it helps much. I think if u want to keep the support bar, it would be more efficient to have a thicker (+4") and shorter intercooler that fits right below the bar to maximize the cooling.

I have a Kuruma Z front do you think that will be enough airflow?
