well since you think the limit of the fuel injectors is going to be an issue, then your already way off base on how this motor your such a fan-boi of works.

 

How do I know I am not giving you something you dont have? You keep it a secret, why can't I?

tune for tune, what engine gives the best gains?

pure and simple question.

 

my information is much more highly regarded than off this forum.

since you know so much

max injector PW vs stroke.

quick! to the search function batman!

 

simple...because you dont know.

the LNF does give the best gains on a tune.
however, its advantage ends quickly after that.

once you cross the limits of the stock turbo, and you start going the upgraded compressor route the LSJ quickly catch's up.

the stock k03-12 is dead by mid 20psi range, with the stock ECM (MAP)and MAF limiting you to the 23psi range ( rite about 31lb/min on the maf) your forced to jump compressors to see mid 300's +

if i take the average price of a good turbo (1000-1200) and dump it into an LSJ, i can breeze past that range.

let alone the cost of charge piping and IC that you'll need with the larger compressor.

i'm not trying to be a HUGE LSJ fan-boi myself here as i've told countless people to get TC's in place of there SC's but that's due to the easy instant gratification people get out of them with a few parts.

baller power will take a long time with such a system being the heart of the engine.

 

um, thats a given. i specified why earlier in this thread.

 

Bosch did a great job with the DI system on the 2009 california ferrari. The technical specs tied to that car will lead you to more information on this system, which will lead you to the almighty limitation you are taunting everyone with. And by simply contacting them as we did you can get enough info to get even more info on this. There's more ways to get this info as well. Lots of people know this.

Happy hunting.

Tune for Tune = LNF. Stop being a cocky **** here and lets get along.

 

what makes you think the systems are cross-compatible?

first and foremost the ferrari system runs a lower pressure yet higher flowing injector.

thats a kinda important part......

 

uh huh.

asking for information by actually not knowing the answer. go tactics. used it before

 

Like I said, thats where I started... I didnt finish my research there... you're getting warmer. I also got a lot of help from my uncle. I never claimed to be a master tuner, just that I have this answer and know more than what you would think about this engine.

 

seriously compare the injector system on a 200k car to a 23k car??? even if they are made by the same exact company....

 

Look can you even read....? I said thats where we started to look as it was the first accessible documentation we could uncover....

Bosch and likely others will develop a full line of high-flow FSI injectors and rail pumps and then all of this will be moot anyhow.... Im not an expert on spray patterns etc, just trying to let you know that perhaps you may not be the only one with access to this info.

My uncle is very curious about DI as he too thought it was a set back. Guess what though? Its not. Limitations sure... workable ? absolutely.

 

im quoting myself for a reason.

 

yes i can very well actually....

 

Spare me the ego and stop pounding youre chest..

Dude, if you think I am saying I know more about tuning this car than you, you are dead wrong. Just that I took my TC out of storage to bring to my uncles performance shop, and he was very concerned about the DI set up in this car so we did a lot of research on this. I have seen you taunt people with this type of question before. In fact the exact same one.


Whats the big deal about us doing research on the fuel system? Why is that so hard to understand. I will honestly need to get back up and read the logs for you. In fact I can email them to you.

Take care.

 

you said you knew the answer to it. there is a very pronounced limit that people are very soon to be hitting.

logs won't show anything because people are more concerned with IDC on those cars when in reality that is NOT the issue at hand.

"i have 40% idc why can't i keep my afr under control anymore??!?"

tuning has very little to do with this actually. plus the fact hpt only gave us 13 tables to play with is a ******* joke in itself. it's kinda hard to **** up with 13 tables and common sense when tuning these things. some how, people still do it.

in comparison, stock for stock the lnf is superior in the tuning aspect. it was given more to work with and detuned out of the box. this is what people are seeing now. i don't have enough seat time with the lnf to make OMGWTFBBQ power with them. no one here in my area wants to take that time. so im not really concerned about that aspect of it. i have more involved myself in the mechanical side of it, and the limits itself of the mechanical parts, however tuning does come into play at some point.

ya know, if people would open their minds a little big to other engines, less bickering back and forth would happen between the car owners about this sort of subject.

 

And thats exactly what set us out on a goose chase. It just wasnt adding up. Very concerning at first... I can't lay claim to that finding, my uncle can.....

What he said

Because as of 1pm today I bought the TC but, I dont get it till saturday. Since it has some tweeks needing

 

hence my question
injector pw vs stroke

in a twisted way it all comes together in the end

 

Well for an opinon for the original question of the thread I myself have driven both cars now (stock) and have been trying to decide between the sc i have and the tc. For myself the decision was easy I'm going to keep my sc. Reasoning for this is.....

1. the aftermarket is there for the sc.(and while it is beginging for the tc who knows how far it will continue with the cobalt being replaced by the cruze)

2. Ive alrdy paid a good amount (and paid off a huge chunk)for the sc why spend even more to upgrade to the tc for a few minor gains ( for all we know the cruze will come out with a ss on it and eat them both even though I for one dnt like the cruze at all so far and would love to see cobalts stay in production)

thats the 2 reasons that really stick out for me at the moment even thought the list continues the more i look at it

I by no means hate the tc's and am actually very interested to see how far the lnf can be taken but it is not the right choice for me right now.

Also I think the bickering on this site is really getting old. We all have cobalts why fight over things like sc vs tc when we could be putting the ignorant people that think the ss cobalts are not better then there cars to shame instead as a group effort. I mean really pick the ss thats right for you and run it for all its worth there is more gratification in that then fighting back and forth on a computer with people that you should be colaborating with. Just my .02

 

I bought the TC because it was brand new, no previous owner.

Had the SC been the new car and the TC been the old car, I would have bought the SC. Again, because it would be brand new with no previous owner.

I think both cars have great potential, and both motors need to be respected. I really don't understand all the bickering. If you think the LNF is superior, buy the LNF. If you think the LSJ is superior, buy it. Different people are going to have different opinions on what is best because not everyone has the same needs or desires.

Jesus, you all bicker more than my gf.

 

well the evo is the most superior car ever built

*chuckle*

:p

 

The biggest thing i notice about some of the TC crowd is that they think their car is far superior to the SC . OLD and SLOW lol. I bet there are alot of SC guys who could have a TC in their driveway tomorrow , I know i could.... but i choose not to. Why?? it's not a big enough of a difference for me to bother . I don't AutoX , and power wise my warrantied stage car is close enough to make it a drivers race in a straight line . Yes the TC is a better car , better doesn't mean far superior.

I know... tune the lnf and it's a different story right???? why would i throw away a new car power train warranty with a aftermarket tune? Wait and see , some of these LNF owners are gunna be pissed when they are denied warranty work , the car is too new to know how it's gunna last with these tunes makin 300whp and even more torque. I'll wait and see the stage kit results , then take another look at the differences.

 

dont you work at layman's? they had a yellow ss/tc at the downtown store for a pretty good price. like 17500 or something close to that.

 

I agree with what you say about the tunes. I dont understand how some1 can buy a brand new car and butt **** a warrenty with the snap of their fingers. If i had the money to not worry about a warrenty i wouldnt buy a cobalt lol. id be chillin in a camaro or somethin.

But stage kits on the SC are great, and im exited to know there comin for the TC as well. And as for what was said about the LNF and not having a big aftermarket because of the Cruze, remember the cobalt isnt the only car with an LNF motor. This gives me assurance that an aftermarket will be around and growing after Cobalts are no longer made.
