Olds ticket to 9s... LS swap adventure.

And the air conditioner! 😕

And the heat. Meh, roll the windows down and go! It doesn't get Houston hot swamp *ss here though.

I'm such a soft fatty, that I was unwilling to countenance a car with no A/C when I was 16.

Dude... I live in canada, if it's high 70s here it's a nice day. Even my dorito dust covered fupa can handle it.

Heat is much easier to add on the cheap, it'll probably need that first.

Quick update for everyone enjoying this show.

As I had shown earlier, The compressor output flange wasn't what I planned it to be, damn turbos... SOOO... I decided to cut it off and weld in the aluminum V-band flange that I had planned to use. I was having a hell of a time finding the right flange anyway...


I got the fuel tank coated with the undercoating, then got it installed. I am going to have to do some touching up on it, for some reason I cant install a G body fuel tank without getting in a fight with the straps. I even got rid of the metric clips on the strap hanger and put some regular bolts on. F-that, stupid metric clip that made my life hell...


In the background I have been planning the wiring and sensors I want to have so I have been setting up where things go and what I want to monitor. I had to order a bunch more sensors and started populating the places that they go.


I have the bracket lengthened for the intercooler, I know I will have to eventually upgrade out of this 3" wide unit to something wider so I planned ahead. First time for everything!


Once the intercooler was in, welded up some IC piping to get rid of some clamps, maybe clean things up a bit. And so I didn't need to buy more piping.


Then Mockup of the header panel. Some minor adjusting needed but it went together.


So I no longer have a header panel in my livingroom. That feels kinda nice. 😊

Dumb question.

What is the point of those sensor manifolds?

It seems like a bracket that just puts all your sensors in the same place?

It seems counterintuitive and I see them all the time. I'd rather run wire to directly what pressure I'm measuring than run a pressurized line to a common place.

I don't want to speak for Duke, but it makes it very easy to wire that. If those are all 5v or 12v sensors, then he can run a single ground and single power wire from one source and then all of the signal wires are of the same length to the ECM. Very clean and neat.

Cleaner wiring is an unintended benefit (that I didn't even think of). The best explanation is it mounts the sensors away from the heat and vibration of the motor so they last longer. Even the expensive ones don't last long on the motor, my fuel sensor would act up on the previous setup just being above the exhaust manifold.

Thanks for correcting me.

I thought engine vibration was more of a concern for stuff with front and mid plates, but it males
Perfect sense to get them away from vibration as much as possible. I just seen the vibration discussion on a FB page with dome sensors. It was discussing the need to run around with spare sensors because they break, and Holley sensors seem to be no better than Low Dollar budget ones.

Nice progress though.

Makes sense. I guess I am used to OEM engineering where sensors are mounted on whatever you are measuring to reduce fluid routing and leak points. I guess that's maybe thermally compensated vs. non compensated sensors? Through testing vs just build?

The lab I work in uses Honeywell sensors that are the same packaging as the lowdoller & others but they are $120 each vs. $20.

I have a couple lowdollor sensors, going to use a combo coolant temp/pressure sensor of his. To be honest my sensors are China made copies, but once you scale there is functionally no difference in my opinion and I have only had one fail.

I would speculate that OEM sensors dont have the resolution for pressure sensors that this style of has, OEM generally just needs to see a "go/no go" condition (for pre-Gen V stuff anyway) or a range for a go condition.

Maybe this style of sensor is just crap?!?! I know the SSI brand stuff we use at work for the big industrial engines don't care and last forever, but they are $4--500 each.

Went to the "city" today for an adventure with the girlfriend and her minions, she allowed me to make a quick stop at the speed shop. Only one last box of stuff and all the little things should be here. I should be able to get the fuel system done now.

Not sure if this 16 injector setup was a good idea or not, because it's HARD on AN fittings.

Make sure to bend the lip of the gas tank up where the straps go around the tank, otherwise you will definitely be fighting it...

I wish I knew that when I was fighting it. Thank you, I'll try it next time.
