Their direct injection debuts in the 335 turbocharged 3L. However, apparently it will also appear in a 272hp 3L. Now that is no more than competitors engines, however they are all 3.2s, 3.4s, and 3.5s.

This regular 4-door sedan engine will be 90hp/liter with straight 6 smoothness, variable valve phasing and lift.

 

sounds like fun....can't wait to see the DI engine from GM premiering in the Solstice GXP and Sky Redline....

 

GM is working on a direct injection 2.2 litre motor. is that the one you're talking about, bigred?

 

yeah, based on their Ecotec architecture of engines, which is the LSx of 4 cylinders.....Looking at the Gm tech websites, it looks to be pretty promising. I will try to get some of that up here, but I can't figure out how to get it from my work to home!! I'll work on that.

EDIT: "there" in this instance should be "their" DUH!!

 

Actually, the direct injection ECOTEC that will be in the Solstice GXP and Sky Redline is a 2.0L turbo pumping out 260hp and 260tq. The ECOTEC has been dominating the 4 cylinder drag race scene, and has been proven to over 1400hp. That's pretty damn respectable.

 

my bad. 2.0. damn.....owned........and I work for them!

 

I've done plenty of research into those cars. I was originally planning a Sky Redline as my next car, but then I decided that I wanted an LS1. I knew more about the cars then the people at the dealerships did. I even found myself educating salesmen on the LSJ (2.0L supercharged 4 in the ION Redline and Cobalt SS Supercharged). Funny name, LSJ, I think it's supposed to mean something like "LS Junior" or at least I think of it that way.

Actually they have had a direct injection motor on the market for a few years. The V-12 engine in the new 7-series is direct inj.

 

educating people at dealers can be done by 8 year olds...


I am quite fond of the LSJ engine, its a very stout motor.

 

ls1 is still better. lol. did any of you guys notice BMW won the engin of the year second time in a row with the v10 from the M5/M6? check em out, the ls2 isnt in there, surprisingly.

 

I'm just going to skip that post

 

Direct injection is where its at. i read an article about it in one of my mags. higher compression, and less comsumption possible. the extreme pressure utilized is what scares me. i think it was in the thousands of psi, for sure hundreds.

 

The thing that got me was the high specific output. 90hp/liter. Much more than BMW's V12. In an engine much less extreme than the M5.

Once upon a time, a modified V8 would be lucky to 12s. Now strong cars shoot for 10s and 9s. And the new generation of DOHC engines are pumping 80-90hp/liter in 2-4liter engines that are running where the V8s used to tread. The Ford Modular, frequently compared to the LSx, may be a poor example.

A few years ago, the Corvette made 350hp, and the Z06 made an outstanding 405hp. Now MB 5.5L, BMW 5L, and Lexus 4.8L engines all make around 380hp. in luxury sedans with heavily muffled exhausts and absolutely no lope to the idle. And a wide variety of 3.4-3.6L 6 cylinder motors make 270-300hp.

This new BMW 6 made 270 from 3L. It implys that a 3.5L may make over 300hp, and a 5L could make 450hp, still in luxury car tune. It makes today's performance engines look weak.

 

your right david! the game is moving very fast at the moment! and it the manufatures that are pushing harder and harder! the last gen M5 was a headline grabber with 400bhp now your not a luxuary saloon without 500bhp and a supercar is nothing without 600bhp! and its things like direct injection that helps them get the extra 1/1000ths out the engines!

as for fuel line presure, why worry???

ever drove a deisel?? well the new gen diesels are running EVEN more presure than that and work fine! also i will try and dig out a vid of an F1 rnginr (renault i think) in a simulation test. they run such high presure that the top injectors (spraying streat down the trupets) just look wrong! lol

thanks Chris.

 

actually BMW has had direct injection since the introductions of the E-66 v12 760.

 

Does your power steering pump scare you too? They can max out at ~3500psi for some units. Ain't nuthin to be scared of. Just don't forget what you're dealing with while working on 'em.

 

correct.

Fuel lines are billet from the factory too. Pretty sweet.

 

yeah the technology for hig fuel rail pressure is already out there. this years 6.6 duramax can hit 26,000 psi, and i think Mack or Caterpillar has an engine with over 40,000 psi fuel pressure. i didn't know BMW already had direct injection. and right on about power to displacement ratios. i used to be embarrassed that a base f-body's 3.8L chevy motor could only make 200hp, while all the other guys were making more power with less dispalcement.

 

Is this the Vid? http://video.google.com/videoplay?do...149644203&q=V8

 

yeo thats the one mate! thanks
