      Of all the paths you take in life - make sure a few of them are dirt.

      • I've been busy. Time is getting short! In short, I've driven it to work two days in a row, had one hiccup and have made 4 psi of boost at half throttle at 2500 rpm, so I do not think I'll have a spooling problem.

        I was really excited to drive it to work yesterday, I stopped at a car wash on the way to work, washed the car, then about ten minutes later sitting in stop and go traffic (mostly stopped) I noticed the coolant temperature rising. Ordinarily it rises at a stop until 200F when I'd have the fan kick on then within 10 seconds it starts dropping. This time by 203F I knew something was amiss. The computer said the engine fan should be on, but it didn't seem like it, so I pulled into a Home Depot parking lot to check it out. Got out of the car and I couldn't hear the fan then right as I was reaching for the hood latch this happen!


        Okay, it turned out that the heater hose popped off the radiator, and upon inspection I think the hose clamp was loose. All the steam is from the electric water pump still pumping hot water out, not necessarily from boiling over. The hose clamp was on the ground and I didn't have to loosen it at all to put it back on.


        So I got 5 gallons of water from Home Depot and was on my way. I was running straight water anyways because tracks don't like glycol spills.


        My poor just washed car


        My Ford air filter was a casulty of the spill. It turned into mush (I took this picture about 30 minutes before steaming).


        So I picked up some 4" couplers yesterday to put a proper filter on it. The tube is a scrap piece of exhaust tubing I had laying around. Tonight I'll cut one that will put the filter in the fender well for cooler air. Though so far, yesterday and today at anything over a few mph the intake air temperature sensor reads ambient temps. Which beats the +40F the stock manifold set always registered!



        I'm still tuning on it. Every drive yesterday it was running really lean so I didn't want to push it. Driving to work this morning I finally had it giving me mid-10's AFR readings as it was getting into boost. Still have not gone over 65% throttle as part of the tuning process. But good to know it can start making boost below 3,000rpm. I currently have the stiffest single wastegate spring that came in the kit installed. I have the other springs on hand to adjust it as necessary. I want to keep the boost down to around 8psi until my good engine is together.

        The transmission is pretty good too! I'm still adjusting the shift points for when to be in and out of overdrive, but it'll bark the tires going into second gear with just a little extra throttle. I'll probably dial that down a little, but it's been fun yesterday and today. It runs smooth well into the 80mph's.

        I think the intake and headers have upped the naturally aspirated power, but its hard to tell since I also upped the gear ratio from 3.42 to 3.89 as well. I think I have enough fuel pump to get me to around 350 horsepower, maybe even 400 horsepower, which would be double what it was making before.

        Now to get the trailer sorted. I head out Tuesday!

        • Sorry for the SNAFU but that's Hot Rodding! At least it was an easy fix.

          BTW - I run Water Wetter and ECTA seems to be OK with that. As I understand it that gives some water pump lube and corrosion protection as well as better heat transfer and evidently doesn't mess up the track in the event of an - event.

          • Great to hear it is on the road, well done TSB.
            Another hurdle over just a few more to go till the end of Drag week, I really hope you can get over them all!

            • The Final Count Down! Tied up a lot of little loose ends and now going on to packing.


              A gratuitous engine shot.


              I need to pick up two more clamps, but have moved the air filter into the fender.


              I thought about just reading the speed off the display, which will always work in a pinch, but decided to step up to an actual speedometer/trip/odometer gauge. It's a Summit brand electric speedometer. I don't have the time to pull the dash to tuck the wires, but this will get me by for now. I'll get a black wrapping on the wires tomorrow. Supposedly will report 0-60 and quarter mile times. Uses 8,000 pulses per mile output from the Mega/Microsquirt.


              I'm going to change the oil tomorrow and figured I'd check the level based on how much oil is added. Here is the level with 4 quarts. Figure about 1/2 quart is in the oil filter and another quart is running through the engine, with a stock 5 quart fill it it should be right under the baffle. Its like the engineers knew what they were doing...

              • Well that's what you get for washing it... Sucker!

                Glad it was an easy fix.
