should be ok. i have mine in the intake. 2 of them on each side of the ^
This is think the the best location for alky or water and the plenum has a higher volume area for mixing and the most heat soak.
Myself and Mark-R were wondering about his gutted intake and the effects it has on the air flow to the runners is now that it has been gutted somewhat.
I'm curious to do some air flow stuff on a stock intake and then look at a mildly ported one (runner ported only) and then compare that to the gutted one that eric is currently running now.
But the water/meth mix is doing more for his combo because he can run 24 psi with no knock and with the straight meth it would rattle some. Also i really like what i seen in the temp reduction.
Brent i think that two m5 nozzles for a water/meth mix would be great on your current combo to reduce the intake temps. I think that you spray the meth on top of the race gas correct?. when doing the water injection you will not have to worry about removing the extra fuel from the tune up.
Letting the wide band do the corrections for you can be a bad thing to it being that far off the chart. you want less that 5 % corrections. The farther away from the actual AFR it has to go meens that it could add too much then take too much away and then it goes lean and pop a gasket.
when using a closed loop system the AFR was ranges a tad bit above and a tad bit below your target AFR. the o2 sensor has to see the motor goes rich or lean before it can compensate so the o2 sensor is alway running behind the engine. so i would play it safe and tray and keep the correction percent from actual AFR to the target AFR to 5% or less.
In my FAST system i only gave it max of 10% to lean it out and 30% percent to richen it up. I don't want the ecm to have a brain fart and take too much out. I Also go to the top of the map and richen the hell out of the VE #'s and pull the timing down just incase it decided to overboost and got into a part of the map that has not been tuned for.
I lost a headgasket last fall due to the wastegate sticking and it made 29psi of boost from 21 while running 110 octane fuel. so always build a safe zone if you can.
i just recently lost a HG again due to a walbro fuel pump failure and it cooked the gaskets and the fast was tring to call for 107% duty cycle and it still was not enuff so things can happen but all you can do is try to prevent somethings.
Also you running a XFI or classic?
