Why are the chevy engine in the IRL series down in power Vs rivals what are the downs in the chevy engine
The engine is a 3.5 V8? someone say this is the Gen IV engine.
What gas they use and how many HP have this engines.
The F1 engine have 870 hp to 950 hp in a 3.0 L V10 and close to 19.000 rpm are the IRL runin that high in rpm?
I hear in the F1 they used neumatic Valves? what tipe of valv are this ones?
the reanult are experimenting wit some engine camless and will pass 20.000 rpm the valvs will work wit some electri works.

 

Other engine builders did a better job so far on their IRL engines than the Chevy.

IRL engine is NOT related to a production engine. Entirely a race engine.

I believe IRL uses 100% methanol (alcohol) like CART, or whatever they are called now.

IRL engines spin much slower than F1. I'm too lazy to look it up now, but I'd guess in the 12K range. The have bigger cylinders and longer strokes, so rpm is limited. They may also have a mandated rev limit.

F1 use pneumatic valve springs and cams, or at least that's still the story I hear. They have experimented with camless engines, but I'm not sure anyone is racing them yet in F1. 20,000 is available with today's cam/pneumatic spring technology, but the engine has to run the whole weekend, so I don't think they are running much over 19,000 on race engines. BMW admitted to 19,200 for last year's race engine. A couple hundred more this year would be about right.

My $.02

 

I hear chevy is working on a camless engine to since some years in a team like they used to devenlope the CVT I dont know how adavance this is but I read the renault engine will used this in somes test in 2005 and will be a engine witout cam and springs the valves will work wit something like the injectors used now I can´t remember the name now. and will have pike TQ at any engine Speed.
Hope to see that soon.

Cool article

 

Great Link this is what I are triying to say but this is even better to what I know.

Could this tech be used in a std. v8 like a lt1, the Pneumatic valve.

 

It could be if someone invested enough money into developing th system. How much is that? Probably millions.

You would want to use this type of system on an engine which needs the higher rpm or variable valve timing, which leaves out the LT1, IMO. It is a very complicated solution to valve timing. Even though the concept may appear simple, the execution isn't. Funny how that often occurs.

I am intrigued by BMW's use of variable lift in the intake on their 7-series engine.

My highly opinionated $.02

 

You guys should be able to find alot of the details with a search. I don't ven keep up with IRL stuff anymore but I know here not so long ago they regulated them to 10,500 rpm. Fuel was, and probably still is, methanol.

Hard to make comparisons between IRL and F1 in terms of $ and the development that comes along with it. The Olds Aurora IRL for instance, was an engine you could purchase for $75,000. I've heard that an F1 engine would cost somewhere in the neighborhood of 10 million. Like comparing the NASA space shuttle to an Estes rocket.

Wow millions... any way l dont want to make it to my LT1.
I know the new Mitsu engines in the lancer rally art 2.4L have 160 hp and 160 lbs/ft Tq. have variavel lift and duration and make the car run vetter times that the SE-R from nissan and 175 HP and 180 Tq. but the mitsu engine have a flat TQ and made this very nice to drive and performs better, this engine dont have hug pike hp and tq but have flat line.
the sistem is the MIVEC and have 3 diff operations
1 for low speed
2 for mid speed
3 for high speed in rpm
the engine is the 4G69 2.4 L.
is a impresive engine and you can buy this car for 18,000$ NEW
so dont have to buy a BMW 7 to have this sistem
I think the new C6 will have a engine wit 16 vavs single cam VVT in some time to race wit the GT 40 and Vipers for the 500 HP class.

 

Didn't Rocketdyne just barely beat out Estes for the Shuttle main engines?
Or maybe that was the solid boosters.

 

Yeah, I think Estes was down on the thrust in comparison. Then again, it's all a matter of scale perspective isn't it?

Since F1 was mentioned... this piece from last year has some interesting facts in it:
