Wow, that is different, a real twist on things. Down to 19lbs boost, now that's pretty serious! I like it.

Actually we are still at 24 lbs of boost. I figured what the heck, you can't tell people you have almost a 1,000hp power if it isn't there all the time right! If I want less boost I can just back out of the throttle, which never happens. I still havn't had it back on the dyno but I have done a lot of ripping on it on the street. It kindof makes you giggle a little bit. The torque when you hit third gear and crank up to 24 lbs of boost is like nothing I have ever felt. That little truck is awesome, handles great drives like a dream, don't get me wrong I miss my old 62 4X4 but that 99 F150 is a great pickup I love it. Now with quieter mufflers it is such a pleasant drive down the road. I have got a lot of comments on how quiet the engine itself runs when I show it off and let it run for people they can't believe how smooth and quiet the engine is mechanically. Don't kid yourself I run this thing really hard. We might run some water/meth injection now that we are running 91 octane instead of E85. Here is the last dyno run we made in case everyone hasn't seen it.

You mentioned about problems with your module overheating. It looks like you have an aluminium heat shied between the electronics and the turbo. I think the aluminium will absorb the heat and radiate it onto module. It's great for transmitting heat like that. It might be worth trying something that will insulate it from the turbo. Just a thought.

You are right, the shield did not initially work. I have since covered it with heat tape from DEI and now it works just fine. I am going to update to a 7al box and a more bad ass coil. Since I have switched back to 91 octane fuel from E85 I am having spark blow out around 17lbs of boost or around 500 whp. I talked to MSD and they said the 6al was not enough for that much boost. Once I change that we will hopefully be able to make some full runs at 24 psi!! Here is a pic of some more stickers I put on.

Did you use the gold or the silver DEI tape? Did you apply the tape to the modules or to the shield?

Thanks

I applied it to the shield and I used the silver tape.

Thanks.

I was wondering the same thing. Why did you switch to 91?

I switched back to 91 because so many stations around here are pulling E85 from the pumps and when I was heading out to a car show with the dyno I ran out of stations with E85 so I has the laptop with me and had to tune on the fly. Actually I like the 91 a lot better my drivability is much better. It idles better and not that I am concerned with fuel economy but it has more than doubled since I switched to premuim fuel.

On the other hand the Y-block has proved it's durability again. I just headed out to my home town for a dyno day and put on over 375 miles with my trailer in over 90 degree heat there and back. My radiator is still the stock one from the 99 F150 and the truck runs pretty warm when pulling the trailer. I runs around 240-245 degree the entire time. It did not get any warmer so I just ran it down the road around 70 mph. It might be a little warm but it ran like a top. Today I ordered a custom radiator for it so that should take care of the problem. I credit the oil I use in this engine to lot of my success. I believe that the Joe Gibbs racing oil I use is top notch. It is HR3 15w-50 synthetic. I would imagine that my engine oil temps were even higher than that to. I pulled my hood off on the way back to my parents house thinking it might run cooler but it didn't help much. Here are a couple of pics from the weekend.



This is when we got to the farm on friday night. The kids love daddy's pickup.



This is after the parade on saturday and parked beside my other 03 F150.



Finally made it home on Sunday night after a weekend of work and pulling. I love this engine. It stole the entire car show and all it does is make power, run great and pull a trailer hundreds of miles a year to car shows. I usually pull at 7-10 lbs of boost and run with the o/d off. The sweet spot with my engine is around 3200 rpm in 3rd gear. At that rpm the engine has great power and turbos spool easily. Pulling the trailer is a breaze at that rpm, it takes very little of the turbos to maintain around 70 mph, and the pickup handles the load great. I did install a new 7al box and a new coil. I think it is going to take care of my spark issue at around 500 whp. I also think I am going to change to autolite AR94 spark plug. It is on step hotter than the 8 heat range ngk I am running now. I think I will be making a few dyno pulls soon.
