Mr. G. Brettin's Slow Motion Leg Hump

gbrettin

Been a little bit since I posted an update. The initial dyno tuning session did not go well. The car was not running properly so a series of tests needed to be conducted. Ill try running through the list... We ran the gambit. This is also to show some of the not so glorious things that happen on fresh builds. Mine may be a little worse... well, becase I worked on it.

1. Before we put the car on the dyno the injectors were cleaned because the e85 sat for a while, couldn't run the risk of a lean cyl. One of the injectors got pinched on installation. This required the fuel rail to come back off and a new O ring to be put on.

Re-test on dyno. Car still running poor. Symptom. I could stand on the gas pedal for 15sec and no power.

2. Reviewed plug wires and saw that 2 boots were not pressed in all the way. Push them in more. The angle is weird and Firecore plugs clip really hard... fine, easy fix. I will take that. No dice. Car still runs like **** where it should make power.

3. Pull the spark plugs and inspect them. They all look good.

4. Verified Spark from coil packs. Good, they discharged enough electricity to kill someone on death row.

5. Pulled the valve covers and checked lash. I measured but didnt account for the oil pressure on the Johnson Lifters. Ordered new push rods and installed. This was an issue but not the fix. Car still ran like junk.

6. Did a compression test to make sure nothing was hurt. All cylinders came back with 185-190 compression.

Dave had a sneaking suspicion that the timing was off. The question was farmed out to a group of local well known drag racers and they all kind of thought the same thing. I went back to my picture archive and looked at the last rebuild 2 years ago. Not sure if any of you remember that, but I pulled the engine apart because there was debris in the engine. I DID HAVE THAT PICTURE! wow! The timing chain had two sets of numbers, one number on the teeth and another near the crank snout. I used the "0" near the crank snout and not the 0 on the tooth. Well.... my car was literally off by 90 degrees!

So... This is where the pictures below take us. I had to take apart the front of my car to get to the timing chain. This last weekend I took it apart on Sat and then on Sun it was reassembled. Much to my delight, we resolved the problem. Also, other problem areas were addressed such as a little a leak from my scavenger pump, heat shielding, and zip tied wires. The "small things" had to be addressed before they turned into massive issues. Example - The heat shielding was specifically for the power steering line. There was a small burn mark on it. I'm certain that would burn through and cause a fire if it wasn't addressed. SO, I'm taking all the stuff we did in stride. The suck was embraced for lemonade.

The car runs smooth (not so much like a promod now.. and I'm ok with that!). Boost comes in and rips at 3800RPM. The short video at the end is just a quick verification of everything.

I permanently removed the swirl pot for the A2W up front... too much of a PITA. I couldn't get it to fill properly. I purchased a Shear Fab 5gal water tank and will have that in the trunk of the car. Ill have the option to run ice I guess.

-Edit - I made 20lbs of boost in the video. Bonus points for someone to say why. Hint: evidence is in pictures. For the people that already know the answer through Discord, keep the answer to yourself. lol






Heatshield.



Top radiator hose is not hooked right. intentionally didn't want it flopping around.

Rusty

Damn boost junkie.

And about 1 year later I finally make some power. lol. Project builds.... fun... yes. fun.

Made a little over 600whp on 16lbs of boost and 550tq. BUT, cyl 7 went cold, I ran out of fuel pump and the turbos need a rebuild. The turbos pushed oil and likely put oil on the plug of cyl 7 (I need to pull the plug to verify). The previous run made 12lbs made 540/540, so that's the last decent run for the turbo before it gave out.

How do I know cyl 7 went cold? I have EGT sensors hooked up and I saw the moment it went cool in the data log.

The fix? I'm getting new Bullseye turbos and will hook up my other Walbro 525 pump.

-Edit - The dyno pull was at 7000rpm and the engine should spin up to 9,000. The internal components should be able to take around 40psi.

gbrettin

Keeping this short. Pictures show the story. Ordered new turbos because my old turbos were junk (said in last post). Owner of Bullseye Turbos made me a set of turbos in 2 days! Picked them up and should be all set to install tonight.

Wiring is going to be a constant clean up until it gets to be OEM like. It's getting there with the wiring tuck. Basically have to keep going over it until it's perfect. I had to replace the battery with new one so I went with a Lithium Antigravity. The constant power was also removed from the battery in favor of a signal wire. That allows the car to actually be off completely at the safety switch AND so the 2nd fuel pump can be triggered at high boost. With that said, the second fuel pump is now operational.

The waterlines were removed to simplify. I'll post those pictures when I crack into the process.

CO2 was hooked up but I didn't really show much about that previously. Lines were fairly simple. That's how I managed to do 16lbs on the dyno with 6lb springs.

Cyl7 dropped because I didn't clip the Firecore boot on all the way. I forgot to hit it with my purse. The IGN1A burnt a hole through the silicon boot. The amount of spark they produce is unreal!

I found the perfect sticker that represents my build... lol

Great update. Love the sticker!

Had to thrash over the last few days to get the new turbos to work. Nothing fit because the Turbonetics frame was different. Turbo mount point was cut and then rewelded. Intercooler had to be cut and welded. Exhaust was a marmon flange on the Bullseye so that was extra tricky, again cut and rewelded. The marmon flange is 3.5" my buddy plasma cut a 3.5" flange with an inside 3" diameter hole the exhaust could be attached to. There's no practical reason to do 3.5" exhaust out the front bumper ... and there's no way in heck i'm fabbing that again.

There were a number of issues found breaking everything down. 6 boost leaks in the A2W, one bolt loose on the up pipe which showed scorching on the gasket, and 4 bad plug wires (3 arced and 1 roasted). Pinched ORB rings on the turbo drains (caused leaks).

I put flanged bolts with pipe dope on threads and copper gasket on the head to stop the 6!!!! boost leaks. So stupid it was manufactured that way. Used the same copper gasket on the up pipes and turbo. The plug wire on the inside of the Firecore plugs got mashed back which caused the arc, the other one was on the header. Happy I ordered an extra set, just incase. New ORBs on the turbo drains. Also had to clearance the oil drains so that there was a tiny air gap.

After everything was together we did some dyno work and got the engine to produce 850whp. WHY NO 1000 HP GREG?!?!?!?! well, the second fuel pump appears to not pull fuel from the tank correctly. Likely a line came off? Doesn't really matter. I can fix it later. I probably wont even turn the power past 600 this year anyway (which is where the first pump stops).

Something I need to change out the twin intake from the car. It stops RPM at 7,000. The twin intake also stops me from easily working on my car... which I apparently need to be able to work on it easily. SO.... I'm going to change the A2W, Plenum and charge tubes to simplify everything. That's not happening for months. I just need to enjoy the car for a little bit. The good news about the changes is that the system fits way better together now and everything aligns on the X pipe, intercooler and turbos.

I'm currently doing a lot of upgrades and changes on the car; however, I'm not going to be posting the progress of that so much. The car is getting cosmetic changes and some revisions on the cold side. I was committed to showing the entire DIY TT LS swap and have completed that goal. I'll leave you with the final picture, for now.

Thank you to everyone that went through the entire thread and/or have followed this over the years. If there are any questions, feel free to reach out on IG@gbrettin, or gbrettin@gmail.com. I don't really monitor forum messages.

geeteezee

Any updates, Greg?

Quite honestly, I didn't think many people read my thread which was why I stopped. A LOT of updates/changes happened to the car. I'll get around to making a long post tomorrow or... tomorrow tomorrow.

If you were down here in Florida I would suggest naming your car “gator bait” based on that first pick in the pond.

Or snappy turtle, maybe hungry hippo?

(I only jest bc you, you dedicated bastard).

Don’t you know only white lotuses can drive under water.

Hah yeah. The car might have finally earned its nickname, Swamp Juice.

It took me 5-6hrs with the power washer spray out the packed in mud. Inside the car I used the garden hose and dawn dish soap. I've got to say, that swamp muck smell gives me PTSD now. Slightly distracting when working on the car.

Thankfully it's coming together! I'm wrapping up a SANS certification but I will get back on the build 10/11. There's going to be a lag on updates for a bit.

FL 4Motion

Swamp Juice! I love it. Whenever you go hit up a drag or strip event THE JUICE IS LOOSE BABY!

I’ve cleaned our JLUR after muddin down here before. Once, never again (on purpose). Fvck that sh1t. I’d rather take body damage on rocks.

And we didn’t even have to clean interior that much since the door seals held. I can’t even imagine the amount of scrubbing etc to get that interior back up to par.

Mr&Mrs

Now that im back in the loop I seem to have noticed something. Im new to social media because I think it paired with cell phones is the demise of the human race lol. Anyway people seem to have applied the same practices to forums. Scroll and "like" then move on. No actual interaction of any kind. Forums are kinda dead and not cool anymore.
