What boost level is everyone hitting with this mod? I haven't spoke to John yet, but I thought I remembered him saying it should be something like 16psi, but on my drive to Whistler on the weekend I was getting up to 20 psi :eek: When I saw this I backed off.

EGT's didn't get above 700, but since I'm new to this way of tuning I don't know what's safe and all that. What's everyone else getting?

I'll let you know what I get this evening on the cut and Furry Creek hills. You bought ATEBs last gauge so I've been gaugeless for a couple weeks while they ordered more. Mines being installed today. I have no idea what's appropriate.
 
Aluminum, what's that? Is it similar to power window tracks I keep hearing about? :D (Hijack out)
 
I am a bit curious to what your guys max egts are set to
Does John do turbo mods with his performance package?
 
As far as I know there is only wrongwayaround that has the turbo mod. It's not done as part of the "power rod mod." I don't plan on doing anything to mine unless it goes. Even then I'm not sure if I'd bother making changes to it.

For clarification I'm hitting 700 degrees Fahrenheit with the temp probe being post turbo (so as I found in another thread a ball park difference from pre to post turbo is about 300 degrees Fahrenheit, so 700 should be ok). Also my boost gauge seems to be pretty accurate because pretty much bang on when it reads 15psi the over boost light comes on.
 
I knew that.... wasn't thinking past my manifold :o

Edit: (I've hit 1250 in my NA 3B going up a steady hill, damn EGT, ignorance was bliss)

uninformed opinion here but on my turbo 2H I've seen 1300F but i try not to go there. I consider 1250F my back off point but have run it pretty steady at 1200F for the long hills pulling a trailer.
 
I just got home and going up both the Cut and the Furry Creek hill I had it floored going about 100-110 km/h with boost at 19 or 20 psi, EGTs at about 1140 F (pre turbo probe) and tranny at about 145 F (had been locked for long time at cruising speed).

Side note: I wish this gauge was in Bar and degrees C, but whatyagonnado?

Sounds like you are getting the same as me then

hi ryan 20 psi is fine,done worries.::bounce2:

Good to hear John, thanks! I just got a bit nervous because I didn't expect the boost to get that high.

Not in the near future for me. I guess if money was no option I would. This is a huge improvement in power and enjoyment, especially on the highway. It's good for now.

I asked John to mount my gauge in the centre-right air vent. The right top of the dash where MonsterCruiser put his is where I like my GPS to live.

What do the digital numbers within the gauge face indicate?

I don't plan to either. I think it would be good if you can get the setup right, but I don't think it would be cheap by the time you do all the fabrication of the piping and everything.

From his other post I would guess EGT and trans oil temp. That's what I have on mine as well.

Yeppers. The top digital temp is the EGT and the lower one is tranny fluid. I'm guessing the temperatures displayed (200 and 68 F) are the lowest ends of the ranges that the probes are good for. I know these weren't the actual temperatures at the time because I hadn't turned the truck on and it was about 4 C outside my house this morning, which apparently is 39 F in :hillbilly: units.

The button on the bottom right of the gauge is to cycle through, believe it or not, 12 different back light colour options: 10 colours and two different colour cycling options. Needless to say, I can now die a happy man.

The gauge is officially a "boost-egt-temperature" gauge so I guess you can put the "temperature" probe wherever you fancy and not necessarily on your tranny.

FWIW, the EGT probe has a temp range of 200-2200 F and the "temperature" probe has a temp range of 68-302 F. So you could put the "temperature" probe on just about anything that operates in that range, I suppose. (insert fart joke here)

Not a bad looking little set up

Now really in intercooler is to combat high egts because of the heated compressed air being pumped into the engine
So theoretically if the engine is tuned nicely to suit this high boost without over fueling and having a safe Max egt you are technically safe?
Interesting, I have heard that the stock ct26 doesn't like getting boosted very hard above 15psi.
 
Yeah an IC would cool the intake air which I guess would in effect reduce your EGT's, but that will all depend on how much you are changing things. Since an intercooler also makes the air more dense from the lower temp you would have to retune things again.

I read 18psi is kind of a limit, so I plan on keeping an eye on my boost gauge and limiting it to that range. Short bursts probably aren't as big of an issue and hauling ass up hills and keeping a sustained level, so that's where I will be careful.
