I've read on here that Meth kits make your car smell but for those who don't have e85 around town it's the only option.
What size throttle body are you using with that Full Blown IM? and how does it compare with stock?
You should polish the IM mate for the ultimate engine bay.

Dont think its a big deal or deterring point though. Id still be running it if I was still supercharged. I loved it. Super effective and steam cleaned your whole top end which is a nice benefit in keeping things clean and functioning well. E85 is dirty in comparison. Like burning diesel fuel.

OP/ Heat soak driving around town is just part of the deal when you have a big hair dryer spinning under your hood, couple that with a huge FMIC and it kills your throttle response. If you already have a vented hood and coolant bypass to the intake manifold then there really isn't much else you can do, other then really make sure your tuning in that running perimeter is refined well to help compensate for your hot/low rpm deficits, like making sure your timing isnt retarding excessively when AIT gets high. You dont want to detonate though either, so again fine tuning to perfection. Most tuners wont provide this level of service.
FMIC heat up quicker in traffic then a water cooling heat exchanger. Now the benefit is once you get moving and get some airflow going they will cool off faster then water/heat exchanger, but its sort of a pro/con double edge sword depending on what driving scenario you find yourself in most. The water/meth injection is very effective, but again you already have to be moving before your injecting, and just cant respond quick enough to combat it 100% from full heat soak situation if your trying to take off suddenly merging into traffic after sitting at a string of red lights. You have to get a few good WOT situations to get the cool air to get into the TB and intake.

The water/meth probably helped clean that up!Hey aren't you supposed to be on Facebook or something?

Water/meth injection is more effective in combustion cooling. E85 shares in some of the attributes but its primary function is being a lower volatile fuel to control detonation. Injecting water actually cools. Ive run it when supercharged, and its very effective if you execute it properly. Your also not ever bound to a radius of E85 gas stations which is lame.
I took pleasure in filling up my water/meth tank in the trunk. It can last a wile depending on your tank and nozzle size and how often your engaging it. The triggering is relative to boost amount you have set not throttle opening, and boost amount at a given throttle % is based on the pulley size your running. If your running a larger pulley/lower boost then you have to open the throttle more to see boost and less throttle with a small pulley. I saw positive pressure threshold at 30% opening with a 3.2" pulley. But you can call the injection to come in at any desired boost amount.
There is a learning curve in the water/meth injection arena, several types of systems that employ the injection differently and so its important to understand this a bit to know whats going to be most effective for your application. I educated myself when I saw its application benefits on my car. Id suggest doing a little online research to get a grasp, or your at the mercy of a rather limited knowledge base of a tuner. Its really a pretty cool thing (no pun intended) which has been around/used since WW2 in turbo aircraft engines and later adapted to formula 1 cars in the 70-80's and many other applications in between.

I run 100-110 iat on the highway with the ap1 iat sensor. I have the front 4 holes cut out of my hood with gurney flaps on the front 2 also have a pair of kings racing vents ducted into the air dam to give the radiator unimpeded air. after multiple 5th gear pulls on the highway with the small jet on the aem water/meth my coolant is 187f oil 215 and iat 80f after I slowed down and dropped 20f on the fluids. I run lower than stock fuel pressure with an aeromotive 340 pump and regulator so at 15psi boost I am around 65psi [peak flow rate] after 70psi it drops off with id1000's and a 1000rpm idle I have no trouble at 35psi idle pressure .

OH and i have idled for hours sorting the tune driving logging then setting in a parking lot with the a/c on and my iat never get over 127f coolant and oil temp drop to 176f coolant 185f oil not sure why your heatsoaking with the cold air intake and the intercooler unless theres no where for that air to go [vented hood]
