Undertray with V-mount?
Undertray with V-mount?

No it's not Turbo'd
Nothing, since you need a low pressure area behind the Rad, and not having a tray will lower the pressure behind the rad, and the try was created to increase the pressure infront the rad, and that's eliminated with the flipping of the rad....

I'll be posting a thread later this week about why it's stupid to run without an undertray, no matter what intercooler setup you have -- and it's not coolant temp related....

I took my car up to the mountains the day after I got her back on the road, and forgot to put the undertray on...coolant temps shot up on hill climbs, never thought about road debris has a potential hazard...needless to say, I haven't run without one since.

The undertray is necessary with any IC. Without one your not going to get any air flow through your rad.
Then you have the problem the guy above mentioned about hitting any objects on the road. It a clean shot into the engine bay without a tray on.

however, i did put my undertray back (needs a lil modification (*ie cutting) with a vmount) just because i was using it to help stabalize my front bumper and what not. and yes, it can help deflect some road debris.

You don't seem to understand the principle - in a v-mount setup, the undertray hinders flow because it increases pressure behind the radiator. In a stock mounted setup, in increases pressure in front of the radiator which is helpful in that case. The best solution for a v-mount is some kind of screen that still allows good airflow out under the car but protects against road debris flying up into the engine bay. I'm going to have to fabricate something like this after I get my v-mount setup done.

Heh, sounds similar to running the Xcessive cast oil pan, hitting a really large rock which proceeds to split the cast pan in half and ruin your brand new $7K engine. I've never done anything like that, sigh, but I digress....
I'd somehow modify the stock splashguard with a group of say two or three square holes, maybe elongated rectangles, and then affix some screen on the top side to keep rocks out. Best of both worlds. I cut the wheel liners for my Mocal oil coolers to breathe a bit better and I've been lucky so far in that I haven't punctured either one with a rock. I plan on screening in that section asap.

Yeah that would probably work. I'm probably going to go a different way though. Maybe I'll even go so far as to do a fg louvered undertray. We'll see what I'm in the mood for when I get to that point.

I would still rather run the undertray then to risk a big rock jumping up and smashing into the radiator or worse. So I will be retaining my undertray with my VMIC. Had to cut it a little to make it fit but nothing major.
