Turbo this baja discusion

[terryly]

OK guys time to update my slow turbo baja transformation Got some parts in the mail and from the local speed shop. A little chop chop here and there, a little twist here and there , make an " S " up pipe a dump pipe and some relocation of stuff and I think I may be close to the final configuration I will need to pick up some 2.5' T Bolt clamps {like 11 more haha}. Brace the intercooler. Weld an 02 sensor bung in the dump pipe Get a banjo fitting for the oil feed and tap my valve cover for a bigger turbo drain. I think I will also make a rear spoiler for the air to water heat exchanger and oil cooler. I was just going to put them both on the roof rack but am now rethinking that So here are the pictures not pretty but should work I hope. I did fire it up just to hear it and back it in and out of the shop IT SOUNDS GREAT IDLING







Picked up a used external waste gate not sure if it is any good or not but will try to find more about it and put it in service
I will still need a boost controller for the ms3PRO ECU,another MAP sensor and maybe bigger injectors and probably more stuff that I never considered. I also need to think about water/meth injection brand style placement and size and if I even will need it for my motor { high compression low boost} hopefully I will update again next weekend with the spoiler build wish me luck. Any and all tips pointers or criticism will be appreciated Thanks for looking in take care

I would make the pressure pipes a little more complete. Solid tube from ex intercooler to after the T. Some more welding, but less possible leak points.
I think you easily can remove at least 6 leak points.

Seems your Wife needs a couple more drinks to get on the same page as you in the excitement stage.......

[terryly]

ya clonebug that is my buddy's wife sometimes she doesn't see the humor in it all sometimes I wonder why she doesn't just stay on the lounge side of the shop haha nothing but questions on things she does not want to grasp but still ask hehe fine woman though puts up with a lot of man nonsense

[buguy]

Haha! She will be more excited once she feels that boost kick in!

[terryly]

OH she likes the buggy just not guys workin on it when she decides she would rather socialize and talk about our feelings BACK to the lounge woman who the hell talks about their feelings anywase especially in the shop.

good idea but aluminum welding is not in our realm right now

[buguy]

I have feelings. Mad and glad!

yup me too

Evening Boosted friends. Was able to get some more work on the turbo for the baja. I got oiling feed and drain lines finished and put on an El-cheapo external wast-gate on. Put the oxygen sensor in. Made a spoiler of sorts to hold the inter cooler radiator and oil cooler I think it turned out pretty cool and I like it . Got all the inter cooler,radiator and pump plumbing done had the pump and fans rough wired and running. Mounted the air box and tucked the oil accumulator on the fire wall. Really digging how it is coming along and like the packaging. Fired the motor up and free revved it for a little bit. It sounded real good so I took it for a short real easy drive. According to my data log I made a whopping 1.9 lbs of boost HAHAHA Probly should not have took it for a spin ......BUT .....on the plus side I am officially BOOSTED. I was running the 1 bar MAP sensor and it seems it tops out at 103.5 KPA then wont report any higher and also the boost goes to 1.9 lbs and does the same. I have a 3 bar MAP sensor and a EBC coming from https://www.diyautotune.com/ . Now I am really chomping at the bit to get the new map sensor in and hook up the electronic boost controller. I am going to try and run it for a bit with out water/meth injection and use the 315cc injectors I have for now and see how it does. If in the future I find I need the meth and larger injectors I will cross that bridge when I get there.
SO I think what I really need to do after I get the MAP sensor in is to change my VE ,Ignition and AFR tables from a naturally aspirated configuration to include some boost figures on the top of the maps. What I haven't got my head around yet and have not researched yet is when running ITB control algorithm is the load setting axis figures the same as speed density in Tuner studio....... example Do I just plug in some larger values for the ITB load axis for my desired boost level and then re scale the figures on that axis ? Here are some photos of my tables





Here is some pics of the set up as it sits now






Alright then so that is where I'm at now I think it was good progress I will steadily pick away at final mounting of radiator and finish the wiring. Hopefully I can get back after the car this next weekend with the boost controller and new MAP sensor.
Thanks for looking in on my the thread. Any insight or advice will be greatly appreciated as always. Please friends stay safe out there in these really weird and troubling times all my best to you ........ What a fricken world hey

Man I really should change my dumb signature line

[rubenski]

Looks good!

Intake temps will be fine untill 10 ish psi.
The ic will do it's work.

Have fun tuning it!

[madmike]

Your gonna need that water/meth ,don't know how good Canada fuel is? ,just wait til u hit 15 lbs of Boost stay Healthy my friend

[rubenski]

Right, I forgot. We have 98 octane at the pump

[terryly]

Hi rubenski I was checking into the differences between north american and European octane ratings and found this tidbit of info seems our fuels are very much the same. I run 91 octane PON but can get 94 octane which would be equivalent to 98 RON. In the future until I go down the meth injection road I will probably start using the 94 pump gas in my buggy but first will need to burn up almost a full tank of 91 dough . Pretty interesting stuff

Europe vs the States

In Europe, gas stations describe different types of gasoline based on their RON rating. It is typical to have 100, 99, 98, 97 or 95 RON with prices varying accordingly. In the States the descriptions look a lot like RON, but they are not.

Pump gas

In the United States gas stations describe the types of gasoline based on the Pump Octane Number (PON). That number is the average between RON and MON. This causes many problems.

If a fuel is 98 RON then it will be 93 PON -> 93 PUMP
If a fuel is 95 RON and 87 MON then it will be 91 PON -> 91 PUMP

Is American fuel quality bad after all?

No, not at all. Contrary to popular belief, fuel quality in the States is as good as anywhere else in Europe. Most Americans think that because they are running 91 octane fuel, their engine will blow up. It is the same as if they were using European 95oct fuel.

In our website you will find RON ratings required for each remap stage.
98/100 RON means you will need to use 93 PON in the States.

95 RON means you can use 91 PON in the States.

Now back to my previous question Does anyone know about re scaling my ITB load tables from naturally to boosted off the top of their head
Thanks guys

Do a "Save As" to get a to get a backup of your tune and copy it to a different folder for safe keeping.
Once you have a backup you can just rescale the VE table and Ign table.
100 is atmosphere or 14.7 so 200 would be 14.7 lbs boost or close enough depending on your altitude.
I would scale a table to 175 or so depending on your boost goals. 7.0 lbs boost would require approx 50% more fuel so start with that on your scale
Change your 100 line to 175 and then work down and space the numbers out to whatever you want for a low kpa.
Same with the VE numbers......put some 150 numbers in the 175 KPA line and scale down to 100. Leave the <100 numbers alone.

It's best to work on the rich side and use autotune on very easy to get your fueling closer. Boost a little at a time and work up to it slowly. Use boost control to keep it down and start at 6.0 lbs.......once that holds a good AFR move the boost up a couple lbs. until you get it.
Listen for detonation and start lowering advance maybe 1.0 degree for each 3 lbs. boost initially and be careful.
