SM105K's SHO BIBLE/BUILDS/LIFE

[SM105K]

Cant wait for the pics - thank for the update!

Also thinking about running a single fogger into the front of the K&N filter, for a pre turbo mister as well. I just want to see if there is a temp drop at the sensor in the intake manifold. I have a three switch rocker panel so running power to everything will be super simple. Not interested in a full blown meth kit either. Don't want to spend the money, and I don't want to deal with meth.

Plus you wouldn't want to screw up that pretty smile of yours with meth.

Lexus Update: Had a shop replace my motor mounts. Got a pretty good deal, because my GF's brother is the shop manager. Best $211 dollars I have spent on the car...lol. Lexi drives so much better now. Literally night and day. Vibrations are gone, things are smooth. Sweet.

Before I sent it to the shop, I did heat wrap the charge pipe that crosses over the hot side of the engine. Since it is only going to be 106 today, I am planning on mocking up the pre turbo water sprayer today as well.

I have a couple of theories I want to put to bed with knock and such.

Lexus Update: So I did some rudimentary testing with my low budget pre turbo water mister. Couple of things caught my attention. It does work on MY SET UP. I removed the charge pipe right before the TB. I had my GF hold the throttle at 3k, 4k, and 5k while I sprayed cold water directly onto the compressor with a adjustable mister nozzle. The air temp that came out of the turbine was noticeably cooler and dry. The air from my turbo, travels at least 5 feet from turbine, through the IC, and all the way back via a U bend, back up over the turbo into the TB.

However, this is where a couple of problems occurred. With the mister nozzle, when you first start spraying it shoots large water droplets into the compressor before it starts to atomize. This causes some issues because I don't want large water drops smashing into my compressor when it is spinning 100,000+ rpms. @Ecoboost_xsport offline mentioned this and he was correct.


I am planning on putting the nozzle through the front of my K&N about 6 to 7 inches in front of the compressor. This should give the water time to atomize I think. Also, this is a high vacuum area. However I don't the risk of the mister nozzle unscrewing and smashing into the turbine wheel. I thought about putting a turbo guard on first, but all that will do is catch the atomized water and turn it into droplets. Also being in a high vacuum area, there is no way to stop the water from being sucked out of the nozzle and supply line, thus causing drops all the time.

So I am upgrading to the AEM V3 nozzle. It has variable flow nozzles, a check valve (however this might not work for my intended application), and a better way of being able to secure it to the filter. So yeah. Progress. Before I go forward with the pre turbo set up, I am going to wait for that it to arrive. However, all the components for the IC water sprayer arrive today. So I will start on that as well.

 

[kryptto]

sounds like to start with atomization and not droplets - more pressure?

 

[SM105K]

With my pump and current set up, yes it could be. Not ruling it out completely.

 

[SM105K]

However again @Ecoboost_xsport just posted a bunch nozzle info and pump info offline, that has me completely re-thinking the pre turbo thing.

That maybe something to work with. I spoke to John about what I was doing, and he said try it. I got the new AEM nozzle on Saturday. When I get home I will mock up the pump and nozzle and see if I get the results I am looking for pressure wise and dribble wise. Also all the pieces are in for the DIY IC sprayer as well. I went with a larger tank for that as well.

When I get a GH Intercooler and pull the frot bumper - I will be hooking up a Cooling Mist from the UK kit - that 119 pound kit is reasonable - PLUS they have tanks.

I used a DIY IC srayer on my GH IC and it dropped the IAT's like another 14 degrees.

I got home and checked to see how the windshield washer fluid pump worked with the aem nozzle. It works okay, but it struggles to atomize the water. So I ordered that water pump from Amazon, and it already arrived at my house. Lol. Just ordered some fittings that will arrive on Wednesday.

SHO Update: About a month ago my 13 modded PP (hehe) crossed over the 100k miles mark. I went ahead and changed the oil and the ptu fluid. Took about 30 mins from start to finish.

First things first if you are serious about PTU longevity and maintenance, you need to change the fluid. Drilling, tapping, and using a fitting that was supplied by @Ecoboost_xsport makes this super easy. Took me about 20 mins (yes that is correct including refilling the PTU).

The Redline Lightweight Shock Proof oil after 20k miles looked great. No stripper glitter, no chunks, and it was just a shade darker than the new stuff I put back in. I am a super fan of the LWSP, and being 21 dollars a quart...is a no brainer.

The oil looked great like always. No chunks, no noticeable engine material, fuel smell was in line with all the other oil changes. There was about 3 ounces of crap in the UPR catch can.

I gave her a good bill of health. Planning of doing a 5 out and 5 in trans fluid swap, along with brake fluid swap the next oil change.

Lexus Update: I have all the peices for the pre turbo sprayer. I just have to figure out if I am going to drill and tap the air filter pipe, or the front of the filter itself. Have some ideas how I am going to mount the pump and water tank also. I want them inside the cabin out of the elements. Should be pretty straight forward.

Lexus Update: I did get it all installed tonight, and did some late night data gathering. For the pulls I tried to do them back to back. First couple of tests were ambient temp water that was sitting in jug in my garage. The last couple were with a 50/50 of water and isopropyl alcohol. One run boost, one pre turbo injection.

Conclusion: It does work on my application. Couple of take aways.

Running a AEM V3 nozzle with the 500 cc jet @ 80 psi. The nozzle is drilled and tapped into the air filter charge pipe 7 inches in front of the turbo. Ambient temp for all runs was 95 degrees.

Just boost: 20 psi, starting temp 120 @3500 rpm, ending temp 146 @ 6500 rpm, steady .75 lambda across pull
Pre turbo : 20.5 psi, starting temp 120 @3500 rpm, end high temp 141@ 6500 rpm, steady .75 lambda across pull

With just 95 degree ambient temp water injected pre turbo, it kept the IAT's lower across the pull and dropped the overall charge temp 5 degrees. It also gained .5 lb of boost.

Same set up, just went to a 50/50 mix of water and alcohol. Turned the boost up to 21.7 psi.

Just boost, 21.7 psi, starting temp 120 @3500 rpm, ending temp 147 @ 6500 rpm, steady . 75 lambda across pull
Pre turbo: 22.5 psi, starting temp 120 @3500 rpm, ending temp 136 @ 6500 rpm, steady .73 lambda across pull

With the 95 degree ambient temp 50/50 alcowater mix injected pre turbo, it kept the IAT's lower across the pull and dropped the overall charge temp 9 degrees. I also gained .8 lbs of boost, and the alcohol lowered the lambda a smidge. Funny thing is I can feel an up tick in power when I squeeze the button to start injection, especially with the 50/50 mix.

So there you have it, it worked for me. I would be lying if I didn't say I am not uneasy with the whole pre turbo injection route. It will wear the turbo compressor wheel and, liquid will pool in the intercooler....so yeah.


However, my experiment is not over. I already have a tapped and threaded fitting in the charge pipe, post turbo. All I have to do is pull the plug, install the nozzle there, and place the plug where the nozzle is now........might be something to mess with.

Either way, I will still be doing the DIY water sprayer for the IC as well. Looking forward to collecting that data as well.

If you're going to spray post Turbo. Is there any chance that your holding tank can hold air pressure? If so run an air line post Turbo to the tank so the sprayer motor won't have to work so hard against boost pressure. It will equalize the pressure between the tank and the charge pipe.

Thank you @smfor this info. So I will need to PM you, it sounds like you are directly cooling the turbines by tapping into the charge pipe. I would need a clear diagram, would Methanol be better than the alcohol?

I am just looking forward to a GH intercooler and install a spray in the grill. Looking forward to your next experiment.

I have seen that with other kits. The previous owner had a dedicated meth kit on this car, hence the drilled and tapped area on the charge pipe. I am probably just going to treat it like a regular meth kit though. I can turn this pump up to 100 psi and see what happens.

I don't want to run just dedicated meth at this time because the holding tank is in the cabin, and if I can make some headway with just alcowater I am winning. Plus since I am moving post turbo now, I can always add ice now. I was weary about spraying ice water on a compressor wheel spinning 100,000 + rpm.

I will post pictures of how I am running the pre turbo sprayer to break it down. Super easy on my set up, that yielded some decent results.

Lexus Update: Alright. Here is where I added the nozzle pre turbo. Just drilled and tapped 1/8 not and ran the nozzle in.


Next was mounting the pump and running the line to the engine bay. I drilled through the fire wall above the passenger side wire loom with same size drill bit as the hose. It was a tight fit but it worked great.

Mounted the pump to the kick panel. Yes there quite of bit of fittings. I will fix that in the future.

Next I soldered wires for the ground and power to the pump from the activation button.



Next, I just add the hose through the top of the igloo thermos and secure it to the seat with a zip tie.


I did relocate the AEM nozzle to the charge pipe post turbo. I will run that tonight and try to get some data. Probably buy another nozzle kit like this and add that pre turbo with the smallest cc jet I can get.


I also went and pulled the plugs out of the engine and took my bore-a-scope and check out the pistons. Plugs were good and the pistons are doing great.
