Pushing it...

Nice numbers. I just wish the power band was a little wider.I realize it's a tall order with the low displacement, though.
Me too, but I ran out of money for turbos.:sadbanana: This turbo is not ideal for most, but it does make some jam. If I can get the timing where it should be, the value of this turbo can be revealed, but currently it's a lot of lag for only 250whp.

I would be happy to put this turbo into the sonic. Good for gas saving when not spooling and give the car sleeper status that beats other sonics at part throttle. The manual transmission can handle this the autos can't Though I won't care if my transmission goes out from this turbo. I have other plans for this car post trans-apocalypse.

Fact of the matter is you've got very little displacement and are pushing over twice the stock output -boost threshold sacrifices must me made. If you look at a dyno for an Evo or Sti with similar mods and twice their stock power the curve looks very similar. Timing tweeks can certainly help but, but you're not going to spool 250whp worth of boost on a 1.4 at much lower of an rpm regardless of turbo or supporting mods. Might be able to shed a couple hundred rpms here or there if you so desire (new cams, head porting, new intake manifolds etc etc), but when you step up turbos you're no longer going to be spooling off of idle like the stock unit did regardless of supporting mods.
Just as another member mentioned I could care less if I have to wait for the power. Nice and fuel efficient during cruise and if I want more power it's just a downshift away.
Except that it doesn't. Preloader killed who knows how many manual transmissions on the stock turbo. The trans is only rated for 236 ft-lbs.

I'm starting to believe I killed them by abusively shock-loading them on launches and dumping clutch at peak power and other baffoonery. I never intended on babying them in hopes they would last though.
So yes, I'd say it's entirely possible to kill the 6-spd manual with 200/225 if you put your mind to it. But on the other side of the coin, as Walker has demonstrated, if you apply the power through the trans, and not at the trans like me, it seems to hold together.

There are several variables involved.
Someone could have a modified sonic and never have a issue with them and someone else could be on there 2 trans on a stock sonic.
You can't say because one person eats trans that it can only handle x amount of power.
We had the same thing on the Lincoln and ranger forums.
Anyways,
I was just referring to the clutch being a limiting factor thing.
The whole thing with the stock clutch vs auto was you could not run the red pill E85 tune on a stock clutch very long vs a auto where you could.

Very early in the beginning of this forum the clutch was identified as the weak point in the power train, and if there is any doubt, notice Crate Engine Depot is offering a GM Performance Parts clutch upgrade, and other forum sponsor vendors also have non-GMPP upgrades on offer, including Morgan in whose section this thread appears.
That said, we know both the trans and the diff also have some plastic parts and those could be a limiting factor, but so far it seems it is the clutch we need to worry about.

Do you have a source? Because I certainly do
GM Family 0 engine - Wikipedia, the free encyclopedia
From the article:
"The EcoFlex engine is a version of the TwinPort tuned to provide better fuel economy and lower emissions. The 1.4 L engine was introduced in 2008"
AND the article on the Volt:
Chevrolet Volt - Wikipedia, the free encyclopedia
"While driving, after the Volt battery has dropped to a predetermined threshold from full charge, a small naturally aspirated 1.4 L 4-cylinder gasoline fueled internal combustion engine (Opel's Family 0[67]) with approximately 80 hp (60 kW), powers a 55 kW generator to extend the Volt's range."
The Volt was release in 2010, as a 2011 model.
When did the sonic enter production again? What about the Cruze?

The a14 turbo first came out in early 2009 then followed the N/A which doesn't the have jets and some webbing on the block that the turbo has and a few other thingsDo you have a source? Because I certainly do

The astra J was the first car to have the gen 3 I've been following the euro guys for some time now
Very true.
I'm not an expert here, he'll a year ago I knew neatly nothing about GM anything built after the 80s.
I'm just piecing together what I've been able to uncover through talking to people, reading, and common sense.
You can knock my sources, but provide no actual counter-source? Guess I've made my point.
I'll concede that I know very little here; and was hoping to have a discussion based on what I did know/understand. Instead you just dismiss my points because I've not been "following the euro guys"
Nice and helpful guys.

What other source do you need the astra J was the first Opel/Vauxhall/GM to get the turbocharged A14 series in 2008 for the 2009 model year then 2009 Opel/Vauxhall released the N/A version A14 that ended up in the volt and a lot of other platforms mostly opel. The N/A block has high comp pistons which are higher then the rated 10.5:1 and no oil jets for the Pistons and the block webbing is different which shaves a few pounds from what the Astra guys talk about it. The Opel/Vauxhall gen3 is so new to the usa that a lot of people don't know about the other A14s some have start stop and D/I which I wish we had.

Because sleeper?
Because I am not a huge fan of loud exhausts on cars like this. However after the kit is installed, I think it may be worthy of some noise. I thought I heard that the stock cat back does hold back the trifecta tune with 42's and a down and mid pipe. Just a little bit maybe like 3-5hp. However the new set up is burning more fuel and this is why I wondered.
