VRSF Race HD core FMIC

Ok,
Due to the sever IAT's I have been experiencing with the M2 here in the Carolinas and the quest to get as much performance out of the BM3 tune I am moving up the the big daddy... The new stepped street has been working great but when the ambient sits at 85-90 for days on end I need more. And since I am still running a cat the heat being generated is off the charts especially on the dyno.

Here is an initial comparison to start off, the install and data will need to come later. Fedex was quite rough on the shipping side and tore the shit out of the box loosing the hardware kit for installation so I am getting another form Tiago. Luckily the unit was only slightly scratched up so we are good to go

Weight comparison:
Stock 7.32 lbs
Old non HD core stepped street 17.4 lbs
New HD core stepped street 18.2 lbs
HD core Race 30.8 lbs

Initial look over the craftsmanship is on point, unit really looks good and it is nicely lightly painted in a silver finish. Side by side...it is a beast.

Really looking forward to getting it installed and logging. I so want to see lower IAT's so I can gain the rest of the HP i am missing out on.

Here are the pics.....

Thanks to Tiago@VRSF for getting one out to me as soon as it arrived......

Nice upgrade. My M2 is still stock and i'm looking to upgrade to the VRSF street intercooler very soon. I'm in south Texas and ambient temp yesterday was sitting at 107 degrees. I was thinking of going for the race but since i'm still stock it might be overkill and may even cause some turbo lag. I will be moving to Miami in a few months so i will definitely need a new intercooler there as well. My job seems to place me only in hot areas haha.

That is MASSIVE! Does it require the same cutting as the Dinan intercooler?

It is supposed to be the largest drop in cooler available, no cutting required
