hi guys.i'm driving 2007 fxt 2.5 eat ,on blouch 18 g 8cm with turboxs tmic,stock injectors with 3" tbe.
on ecutek n 280 bhp at the wheels. tuner unwilling to get higher state of tune except for meth injection for margins of safety.at 1.5bar wot.
m i leaving anything else on the table before going for meth? looking to crack 300whp,to bring down 0-60 to below 5s. currently at 5.6s.damn.
he recommended labonte.how does this compare to aquamist/coolingmist/aem that u guys prefer?tks.

Why are you apposed to bigger injectors? That is your limiting factor and the reason your tuner will not go any further, your injectors are maxed.

^^Agreed. I find a lot of people now rush to get water/meth kits without exploring all other options first as it's an easy way to get power. Cetainly even going up one size in injectors and freeing up your intake may be all you need. If you install a meth kit you will then have the added problem of sourcing methanol and also making sure your injectors don't clog etc. Sure they are great but I wouldn't want it on a daily driver.

I have the SMC Meth kit and I have to say the best thing I've done to the car next to the VF39 in regard to performance. One of my complaints with turbos in general is the loss of power in the summer. Now I have a lot on tap regardless of how warm it is. Still a loss in hot days just not as bad with out it. I've been meaning to write up on my experiences which have all been good. I'm using the SMC kit where the wiper tank is replaced (I used the FXT one FYI since it holds more than the WRX one). And have an aux tank for the wipers (which required a custom fab too since we have 2 pumps one for front and another for rear wiper). Also tuned with EFI Logics (Chris) who did a great job. Look for Forester and Alex Geslani in their dyno database and you'll see why I'm grinning everytime I drive =).

PM me for info on what's diff with FXT install.

Mustang dyno numbers (low reading dyno):
93 Octane 285 hp 300 ft/lb
Meth + 25 psi 308 hp 364 ft/lb
My regular Meth tune 23 psi 301 hp 359 ft/lb

Note additional benefits are cooler running engine overall and meth acts as a bit of an engine cleaner as well. You can also add a 3rd party fail safe as well that will meter boost / meth pressure and kill boost if certain thresholds aren't met. I'm thinking about install such a system not sure.

Only complaint I have is the effort and cost of filling meth. Keep in mind cost of $52 at least for me for a 5 gallon tank of meth which can last from 1-3 months depending on how you drive. I personally don't run meth in the winter since my winter tires aren't as good as summer and the car is plenty fast in the cold weather =).

The stock injectors are without a doubt your limiting factor with that turbo. In fact, I've maxed mine with a VF43. But even with larger injectors, a safe tune will be quite rich as fuel is dumped to cool the cylinders and prevent detonation.

Instead of larger injectors I too have decided to go with water/meth injection - I am currently installing an Aquamist HFS3 system. I chose this sytem because (1) it used IDC to regulate flow and (2) it uses a constant speed/PSI pump with a "fast acting valve" to control the injection (just like the fuel injection system in our cars). Other systems vary pump speed to control the amount of injection. It also uses a flow sensor to detect under/over flow, which will initiate failsafe mode (drop boost to wastegate pressure).

The end result of this install will be reduced IDC, reduced EGT, leaner A/F ratio, better protection against detonation and a gain in HP/torque. Larger injectors alone would not provide all of those benefits.

was told by tuner that injectors r in the high 90's idc,with some headroom left.changing to larger injectors was an option but did not seem bang for the buck as ,tho they were slightly cheaper than the meth system,i doubt that retuning will get me the 20-40 extra bhp from a meth system.understand that there will b recurring costs with the meth system.wat is a realistic return of additional bhp from larger injectors? all options r still being considered.any feedback on labonte?tks
