Bluezones build

[Bluezone]

Just some updates to my thread.
Set my personal best last september. 12.85 in the quarter. Found a few boost leaks afterwards. So I might have went quicker yet. Have to wait until later this year.



Looks like I've got my launch pretty well down.
Other than that I haven't been doing much with the car other than setting it up for winter use. Contemplating some aerodynamic drag removal.
Practiced a little weight reduction on the car by ventilating the under engine pan to improve airflow. Blocked off the big NACA duct to see if it helped. It didn't so went back open. Overall seems to help cool down and general running around.



Worked on my redneck twin filter box today and cleaned up some of the transitions. No different results than running twin cone filters. I used it during my last run last september. Definitely cheaper though then to cone filters. The filter is due for cleaning from the looks of it. Job for tomorrow. LOL

You do realized the black rtv would look less like a freshly filled diaper when the hood is open?

 

[Bluezone]

Unfortunately in Canada at this time it's impossible to find black RTV. Believe me I don't like it either. And now I can't get that image out of my mind. Thanks LOL. By the way you can't see it with the filter box installed.

 

[FrankK]

Spray it black.

Just a little update on my build. I am trying a little experiment with the turbo exhaust type things. I scooped I used set of turbos and added a divider between the internal wastegate and the exducer port from the turbine. I also did some reshaping and porting of the exhaust housing and compressor housing. Plus a little closing up of the tolerances and smoothing the flow into the compressor housing.
I'm working on getting them installed over the next couple days.

 

[FrankK]

BlueZone,

What are your thoughts with the divider?

 

[Bluezone]

BlueZone,

What are your thoughts with the divider?

Well for some turbos you can get divorced downpipes. This helps spool up and improves turbine efficiency. There are also turbochargers that use external wastegates. They're more efficient as well.
What happens with internal wastegates, is that the wastegate blows across the turbine exhaust port. This disrupts the exhaust flow coming out of the turbine. It also increases the pressure seen by the exhaust side of the exhaust housing.
The short version is by using a divider you decrease the wastegate duty cycle. Meaning the wastegate stays open more. So you should end up with less back pressure.

 

[Bluezone]

Still working out the Kinks with the exhaust housing divider. Looks like a shorter is the way to go. Found I had a boost leak. Center housing to compressor housing o-ring isn't Sealing properly. Going to add some silicone to shore up the housing seal.
Looks like the short-term fuel trim doesn't drop below 1.0 up to 6300 rpm, with the shorter divider. With the stock exhaust housing I see a STFT drop off below 1.0 around 5300 RPM.

Found an early Ford Edge with 3.5 L and towing package. Had an oil cooler on it. Wrong, early style, oil filter adapter. Single Hollow bolt instead of three smaller bolts. To hold it to the block. Swiped the cooling fan from the edge.
Unlike the SHO and MKS EcoBoost, this has two equal sized fans. Haven't measured to see the diameter. From looks of pictures, size wise, it's right in between the large and the small fan on the EcoBoost radiator. So likely a wash on total area. The important thing is it has eight instead of seven blades like our fans. So should be able to pull more cooling air. That's if it does fit.

 

[Bluezone]

Install the new fan combo today. Had to switch over plugs to match the stock controller module.
Measuring from outside to outside of the fans. The smaller stock fan is 13 and 1/2 in. The rim is about a half inch thick. So 12 and a half inch fan.
The large stock pan is 15 and a half inches with a half inch rim. So 14.5 in.

The edge fan set up uses two 14 and 1/2 in fans with a half inch rim. So 13.5 in diameter.


It seems to work pretty good overall. Noticeable temperature difference between the air coming out of each fan. Meaning the ready radiator Inlet and Outlet sides have a air temperature differential just like it should. The only downside is the new fan shroud crowds the stock air box by about an inch. Which also means air has more room to make its way out from the radiator hand through the fan openings.

 

[Bluezone]

Well it looks like I have a seized piston ring. So unless something changes with a few things I'm trying it looks like the end. So I'm likely to be posting up parts for sale within the next week.

 

[FrankK]

Sorry to hear that BlueZone. Try putting some penatrating oil in the spark plug hole and see if that might break up the carbon.

I tried that and didn't seem to have any effect.

 

[Bluezone]

Well I tried one more thing. Adding some seafoam to a fresh oil change. That was a no go. Compression is presently about 10 psi on cylinder No. 2. All the rest are around 175 PSI.
I will likely be posting my Gearhead intercooler and PPE stainless steel catted downpipes. The turbos are serviceable as far as I know. I don't think anyone's going to be interested in my divorced intake manifold. It looks pretty crappy. It was good at knocking a few degrees off the intake temperatures though. I have a noise maker delete pipe as well. Will probably start posting them up at the end of the month for sale.

 

[Bronco2fan]

That sucks. You're not gonna try for the rebuild? Seems like such a shame. Good luck with whatever you decide.

I will turn 64 in a couple months. Really don't picture myself doing another engine rebuild at this point in my life. My third generation Supra was the last rebuilt I planned on.
I learned lots of cool things for working on this car. The aerodynamic mods are worth a couple miles per gallon. Exhaust cam timing is not optimal. This is an unfinished experiment though.
Keeping the the intake manifold cool is very important.
Helped in the finding a LSD for our cars and searched for a aftermarket cam supplier. Figured out how to manipulate the RDU, unfortunately it's too fragile to screw around with.
Played around with stock turbocharger efficiency mods and found it it has possibilities.
I'm pretty sure that I found the optimum intake length is about 13 in. Should give a boost in the 5500 to 6300 RPM range.
Enjoyed doing my best to answer people's questions to their problems.This is a great group of guys on the forum. I'm still still planing to be hanging around for a while.

Oh, I get it for sure. I'm 64 now and find I wake up with back pain everyday lol. I bruise from just washing the rides. Normal maintenance starting to be harder and harder. But I really like the SHO, and if I can't fix it, I'll pay someone to until it becomes unrealistic to repair.

 

[FrankK]

BlueZone do you have a camera you can put in through the spark plug hole to check the condition of the cylinder? If the cylinder is not in bad shape you might be able to just replace the piston and rings and rehone the cylinder.

 

[Bluezone]

I have an inspection camera and I've already run it down the spark plug hole. I couldn't see anything that looked suspicious. Mind you the cylinder walls were so shiny it was hard to discern anything with the camera.
It being a rear cylinder makes it kind of hard to hone out while it's still in the engine bay. I know it sounds a little sketchy to do that. I've done it before with my very first Supra. A 1982 model. When I was done everything I did with it, it would walk all over 5.7 liter tuned port irocs. That got sold to a friend who had someone chase him for 5 miles till he stopped for gas. Just to ask him what the heck was under the hood. LOL

 

[Zpak]

Kinda bizarre it would just lock up like that. Since you have a tiny cam did you get a look at the valves? My brother-in-law’s 3.5 F150 ate an exhaust valve.

Well there had been slightly strange symptoms that I had dismissed unfortunately. Just didn't know it was leading up to this. Hindsight's 20/20 you know.
No definitely not a dropped valve. I've had the valve cover off. Compression was around 50 and after trying a couple things, it dropped down to 10 psi. Lots of blow by.
