Maybe. I don't think your going to be able to beat the 13t though. When i went to the 19, my spool was slower. It did feel like it made more power overall, but there was also more lag. I really don't know how you can get what your looking for out of a single turbo. I was able to get 30 psi and if i remember right i was spooling around 2200-2300rpm. At 30 psi the 13t was terribly out of its range.
I wonder if a nice expensive newer turbo would do it? More efficient might be better. Seems like to get more boost, you would want a bigger turbo, which surely means more lag. Might be chasing your tail with a stock engine. The guys making big boost with small engines aren't doing it on stock parts and they aren't boosting early either. I'd make 100% damn sure you don't have any leaks anywhere. Maybe get a valve job and some stiffer valve springs. Although at the cost of that, new heads might make more sense. For me locally, it was $150 each for a good valve job. I bought my new heads for $400 on sale. Just made more sense for me.
Spending the least money, nitrous is hard to beat!

I don’t think you can do it with one turbo.

The new nice turbo would help and is probably the smartest move time wise and cost wise in the end.

The 13t works it’s just not as optimal as I would like though I’m about to run e85 so that may change my 13t stance a bit.

All in all I’m still not sure but not super important gonna get some tuning in today.

I'm super interested to see what you get with E85.

Had to run into work today so decided to run autotune on the way in after cleaning up the VE table last night. Got everything cruise related sitting really good. turned on EGO and and ran it a bit more and think I got everything relatively done minus my high boost settings.

Let me say that though I would see boost around 2300 before it wouldn't pull till 3500 or so, I am assuming I had a large exhaust leak at the turbo as this thing feels like a different car and is deeper into boost earlier then before. Though not without issues

I am not quite sure what is happening on high boost running the same electronic controller as before with no change in boost duty cycle but I cannot break 11 psi of boost! In a log it will build then the AFR leans out then builds pretty much from 4500. My FPR is still plumbed in the same so I am not thinking its that and the tune though rich should be safe and allow it to pull boost.

I am thinking disabling the water methanol injection to get a base tune then re introduce it. thoughts?

I wouldn't tune without the water injection....If it's anything like mine the ECU is leaning out the VE table to compensate for the extra fuel from the Alcohol and if you turn it off it will be lean. The ECU will retune to make it richer then once you turn on the water it's going to be all messed up again.

My 100 kpa at 3500 rpm and higher is the same number as my 275 kpa line at that rpm.
A couple weeks ago when my W/I didn't kick on I got a bunch of detonation because I didn't notice it wasn't working. It went from 12.0:1 afr up to 14:1 afr without water. My intake temps were up a bunch and those two combined made the engine ping.
I'm not sure where you have your timing but it's pretty critical once you get up in boost and you start changing even one thing.

Thanks! I’ll leave it on and maybe adjust mine it match something similar to what you have. I’ll have to post a picture of the log as it’s strange to me.

Timing is relatively conservative, though I’ll have to look it up.

Timing is engine specific....What yours might tolerate would not necessarily work on mine and vice-versa.
You can work your way up on timing and once it pings lower it until it stops....or run conservative and leave a little power untapped.
Ambient intake temps have a fairly large impact...at least with my engine.

So after following the advice given on here I have got a running car.

Now I’m having some fine tuning issues and I’m not sure how to fix them.

1. At cruise I am getting a lean backfire / pop and I can watch the AFR hold around 14.6 to 16 or 17:1

2. If I turn on AFR authority table it gets more frequent.

3. PID makes things tolerable but swings pretty wildly.

Last question to the e85 folks are you just set for flex fuel or are you running duel fuel or flex map? Or is it as simple as throw in e85 and let the flex sensor tell the ECU to adjust?

Thanks for the help hope all the US folks had a good Thanksgiving!

Hummm.... that's weird. Not sure what's happening there?
I'm a bit backwards, i run E85 all the time, but when i do run regular gas, i let the flex fuel sensor/ECU make the adjustments for me and i turn off the boost controller so i run on waste gate pressure (12 psi).

Buguy - do you have any thing other then flex fuel enabled?


The more I look at my “new” tuned VE table the more confused I am on why it didn’t like my fuel calculation change and my original VE table.

I’m going to try a new version of that tomorrow.

I also am thinking that chasing a number that I think is appropriate is not as important as how the car drives and behaves. I got to thinking about after I read Clones post about timing being an engine specific setting.

I don't think i do?! Been a while! Flex fuel just changes it on a percentage. I will get a few logs out to you tomorrow. Work has been crazy as usual.

Why is this thread so far down the list?!

The car is in Daily Driver mode. It’s hard to mess with it when I have to rely on it.

I’m working on getting some stroker parts together and looking at an engine build but I haven’t gotten anything worth posting about.

Merry Christmas gents.

I just did a quick look at your upcoming weather. Better find a little 12v heater for that thing!
