My turbo charging results

[arnott1t]

My boost used to max out at 12psi. That was perfect since that was all that was reccomended. Now that I have improved the intake it makes an easy 15psi. Have to install my controller now to make sure I don't reck anything. Its amazing that changing that one small part of the intake gave me close to 3psi more boost. I soooooooooooo want to got to larger exhaust now.

I figured that might happen, the less restrictive things are the faster the turbo will spool and the higher it will spool (more boost)

I wouldn't install the controller unless you have boost spikes (or if you do, turn it up for more psi than stock) the engine should be able to handle a few more lbs

Install the bigger exhaust and I bet you will get even more gains

Even if you don't want more maximum psi and install the controller, the pressure should come on at lower rpm's for more power across the band

Where did you put your boost fitting?

My boost port for the gauge is right in the outlet of the turbo. It does spike a bit when I shift and quickly let off the throttle but not a ton. I think I will still regulate it down to 10 or 12 psi unitl I turn up the fuel. Wait and see.

Well this weekend we did some more work on the cruiser. We first turned up the fuel. I wasn't sure that I was doing it right but then could tell pretty clealy that I did just fine. The power gains were enormous. Where the turbo alone added power in the mid range the fuel turn up and turbo really gave it some more power in the bottom. When I first got in and stepped on it my head went back just a little bit. This has NEVER happened in our cruiser before. EGT's went up by about 100f at max. The still sit around 700 cruising at 110 on the highway. My max is probably around 1000 or so now. I set boost with the controller at about 12 psi. My stats since the mod went like this.

Original= small tires, no mods 0-100kph=24sec
Turbo= 33" tires and turbo 0-100=24sec
Turbo and fuel 0-100=18sec

These numbers are rough. But they sho a decent increase in power. The biggest difference with the fuel and turbo I noticed was in the climbing. Now from the pics above you can tell there arn't many hills around here but I managed to find one. The cruiser now feels better in High range 1st than it used to low range first. The power is awesome. Blips of the throttle are very responsive.

I have started to read a bit on intercoolers. I would like to try and put one in. I feel my crossover pipe going from the turbo to the intake and it is always warm. Close to hot but really only warm. I'm guessing like 90f or so. I would like to get that cool or cold.


Still need to do some reading and then look for one.

Now you need an intercooler

And here are some pics of the piece I fabbed up to clean up the intake stuff

From the pics it seems that you have used iron tubing between the aircleaner and the turbo. I have read that this is a very bad idea, since the pipe will eventually rust on the inside due to condensation from the intake air. The rust will at some time flake and be sucked in by the turbo, thus damaging the turbo and the engine. I know that a lot of turbo installations are made using iron pipe, I used to have one myself, but the whole rust thing makes a lot of sense, just something I did not think about before I read it.

An idea for you could be to take the iron pipe, when you are absolutely satisfied with the position ect., to a shop and have them make a new in aluminium or stainless using the one you made as a template.

Great install btw.!
