GEE-OTTO Posted April 14, 2015 Share Posted April 14, 2015 (edited) PW Verti-Cooler I wonder if this would fit the LGT the same? The scoop baffle must be different to route the air rearward. Still a nice option given how well the original PW was received. Edited April 14, 2015 by GEE-OTTO Link to comment Share on other sites More sharing options...

Flinkly Posted April 20, 2015 Share Posted April 20, 2015 Sounds weird, but i wish the core was smaller (optimized for 350hp-ish). Fantastic idea though. And i like the looks of the splitter.

ras06LGT Posted April 20, 2015 Share Posted April 20, 2015 Just curious as to what this offers over the comparably priced Grimmspeed unit (which was specifically designed to it our cars)? Link to comment Share on other sites More sharing options...
Flinkly Posted April 20, 2015 Share Posted April 20, 2015 The GS unit is NOT designed to fit the LGT or the OBXT. and from what I've heard, it sure doesn't fit the OBXT very well. not to say that any aftermarket TMIC options fit perfectly. It WAS designed to fit the 08+ WRX, and it just happened that the 08+ WRX is similar to what the 05-08 LGT/OBXT is for TMIC placement and attachment. ...but to what I think you were trying to ask, this rotates the core from the nearly flat position of "all" Subaru TMIC's, and puts it in a nearly vertical position, so that the air doesn't have to make 2 nearly 90 degree turns to go thru the TMIC core and cool. so in theory it would get better airflow thru, causing better cooling over an equally sized flat TMIC. science, FTW. * Build Thread * 26.53 MPG - 12 month Average * Link to comment Share on other sites More sharing options...

GS fits pretty well on an OBXT, IMO. The splitter is a bit off, but can be fixed without much fuss really. Install is the easiest of any intercooler I've dealt with--stock, Perrin, Process West. The airflow equation is more complex than just the front side of the intercooler. I don't know who is right, but GS (and subaru also, based on their design) wants the airflow to go down and out the bottom of the car. PW is now arguing that it's better to go across the top of the transmission, and some argue that it's also just smacking into the firewall behind the verticooler. Also, at a certain point, the airflow over a TMIC will simply be "enough" and additional airflow really won't help much. You can only remove heat as fast as it transfers into the fins, so if your airflow is enough to do that you're talking about minimal return.

Flinkly Posted April 20, 2015 Share Posted April 20, 2015 Oh, not saying the verticooler is awesome, or works (better than something else), just stating the idea behind it. It is an interesting idea.

Streetlegal Posted April 21, 2015 Share Posted April 21, 2015 Is there a splitter behind the verticooler? Could you not make a splitter post intercooler to produce a smooth transition for the air to flow close to the same direction as the OEM path? I like the idea but the engineer in my feels like it can be improved upon. The airflow is going to be better with the PW IC because of the lack of 90° bends that Flinkly mentioned. Makes a large amount of turbulence in those bends and slows down flow. You want a little turbulence within the IC itself because turbulence increases heat transfer but before and after just hurt flow. Engineering FTW.

Rhitter Posted April 21, 2015 Share Posted April 21, 2015 GS and PW got into a little fight over it. I think PW started posting about the Verticooler in one of GS threads (I can't find it right now, was probably removed). Essentially GS said we checked all angles of the intercooler and found ours to be the most efficient regardless of what PW is saying. It's one of those things that I am not sure we will ever really know the answer too. I do remember reading that Delicious tuning has found the stock sti intercooler to be among the best (as intercoolers go) and the GS STI TMIC didn't really offer that much in non-road race situations (in AutoX it was heat soaking too much to actually be useful) (There was a NASIOC thread about one person experience) I was talking to M Sprank recently and he briefly mentioned that they had seen good results with the Verticooler, but I didn't ask for more details.

WRX USA Posted April 21, 2015 Share Posted April 21, 2015 (edited) Process West did do some testing of their Verticooler: http://www.processwest.com.au/process-west-verticooler-intercooler-system In fact going through data we have gathered over the years from other test sessions tends to show that Verticooler is as effective in charge-air cooling under race conditions as a traditional front mount setup….but all without the inherent response delay that long inlet tracts deliver. Here is the response from Grimmspeed about the Verticooler, after Kev from PW posted in their interest thread: http://forums.nasioc.com/forums/showpost.php?p=42844608 Edited April 21, 2015 by WRX USA Link to comment Share on other sites More sharing options...
monsterface Posted April 21, 2015 Share Posted April 21, 2015 The verticooler will not fit our cars, I've spoken to kev @ process west and they will not be designing one for LGT/OBXT fitment because of hood clearance issues. Link to comment Share on other sites More sharing options...
Flinkly Posted April 21, 2015 Share Posted April 21, 2015 (edited) sounds like an OBXT needs to do some DIY work. since we have more clearance to the hood than LGTs EDIT: assuming you haven't removed your body spacers...

I call BS. What he meant to say was that they won't be designing a splitter for an LGT, much less and OBXT, because the market is too small and they don't see a ROI. I'm fine with the business decision, but at least be truthful. "Bullet-proof" your OEM TMIC! <<Buy your kit here>> Not currently in stock Link to comment Share on other sites More sharing options...

dahoseman Posted December 2, 2016 Share Posted December 2, 2016 to revive ..... I'm still curious if anyone has installed installed a verticooler in an OBXT (or LGT). It doesn't seem like rocket science to make it work. I thought that the idea of the verticooler wasn't completely that it intercooled any better, but that it was less prone to under-hood heat transfer in stop-and-go traffic. Am I wrong about that?

Isn't it occupying the same space as the GS unit? I.e. hanging over the turbo? Unsure how it would be less prone to under-hood heat transfer when all the conditions that cause under-hood heat transfer remain the same. Unsure anyone with an LGT / OBXT will try it when ProcessWest explicitly says it will not fit due to hood clearance issues. My OBXT build Link to comment Share on other sites More sharing options...
l88m22vette Posted December 17, 2016 Share Posted December 17, 2016 It seems like it could be a pretty easy DIY with some creativity. I still want a better TMIC but plan to use a small puller fan on the back, that'd be the best improvement for both intercooler and under hood temps. I know it's been discussed and done but it doesn't seem like a common mod. Link to comment Share on other sites More sharing options...
Max Capacity Posted December 18, 2016 Share Posted December 18, 2016 For those worried about heat soak from the turbo. Some day after you shut the engine off, go feel the hot side and then the cold side of the GS tmic. I find the cold side to be cold. Isn't that all that counts...
