Default Allow me to introduce myself!

Name is Evan! Live in Houston, TX. Got a few things in the works for the ISF but here is what I have so far

Custom D3PE Cold Air Intake (still testing)
Rear Y-pipe/muffler delete
305/35/19 Mickey Thompson ET Streets on stock wheels

Here is the stock HP v.s. how it sits with the current mods:















Stock times I ran 13.19 and after the mods we got it to a 12.8 this past weekend. Much more in store!

Still tinkering and testing with the smaller mods until the engine management system is done

Welcome! That's the first cold air intake I've seen for our cars, instead of the short ram types.

Am I reading it right that there's a 40HP difference between stock and modified with CAI and exhaust?

Pretty good numbers!

Interested in that intake, kinda curious about it. Looks like a pretty large diameter pipe....but I don't like how it makes the engine compartment look "unfinished" on the rad support etc.

Correct the only mods are the intake and rear Y-pipe removal. Unfortunately this particular unit cannot keep the stock scoop on there and gives the "unfinished" look but this is just a prototype so that could still change

love the look of the CAI... too bad the RMI scoops that some of us have would make this CAI pointless. Those back tires look beefy too! I like it!

It is definitely a tight fit but not too much modification needed in my opinion. Moved a couple brackets slightly, removed brake duct(simple to unbolt), and you do have to trim the plastic below the lower front frame rail a little or just remove that piece.

Thank you! But I think you have it the other way around. This intake would make the scoops pointless

Wow interesting CAI idea! I don't know how you fit those fat tires on stock rims, but they look good! I also don't know how you gained 40 whp lol but Welcome!

Hello and welcome. Curious though... 324whp seems a little low for stock. Granted, a dyno is useful for measuring gains over a baseline in similar conditions, so it doesn't much matter what the baseline is, but I wonder if 324whp wasn't due to bad atmospheric conditions on that day. Put another way, can we really attribute 40whp to the intake and muffler delete, or could it just have been better conditions on the second day? Intakes, even CAIs don't tend to add a whole lot of power on the dyno, because most of the additional air that is added to the AF mixture comes from the cold air rushing into the intake at speed, but that doesn't work quite as well with a fan blowing onto a stationary vehicle.

Also, did you run the 13.1 with the MTs, or was that with stock tires?
