Are there any reverse flow cooling aftermarket blocks?

I was wondering if there are any... i haven't found one.

with the upcoming 7L engine from the c6 z06 and its new heads that supposedly will flow around 370cfm (which I still don't believe). Having an aluminum 7L engine is a neat option or upgrade.

Since aftermarket aluminum blocks are not as easy on installation of factory parts and since aftermarket aluminum blocks are extremely expensive, the iron was pretty much the choice to go. But... with the iron blocks, are there any that have reverse cooling?

i dont know what they flow but i do know they are factory CNC ported heads.

I think the last figure i heard was 200g/s or minture or something like that at SAE conditions.
theres mass flow, convert it to volume flow after you google air density

I don't think so, there was a dicussion on this not too long ago and they were talking that you could only have one custom made and that it woudl be far too expensive.

Why not? Im not sure what type of heads are no the new Z06 but for comparison C5R heads are supposed to be able to flow ~400cfm

And why do they ONLY make 600HP? shouldn't they make around 800 with 400cfm flow?

It probably has a very mild cam in it, with 427ci and 370cfm(assuming they flow that stock) it would be really easy to make 500hp.

If they put the ACTUAL cam from the z06 they should make EASY 600HP with the 370cfm flow.

I believe the air intake is the size of a straw on that car due to the rules of the Gts class

I have a silly feeling there will be a Z06 (nice car) anda Z06"R" or superZ06 to help in the GTS class and such.

That extra few inches they cut on the C6 is going to hurt them on the track. Concidering the great sucess they had this year, dont expect them to stop. And hell, when your budget is $20m, its awfully hard not to:)

i thought making it shorter was supposed to make it faster? though that was why they did it...

the car is shorter but the wheelbase is longer

aero


ever notice how long supercars are? look at the s7

the car is shorter but the wheelbase is longer

sure about that? wonder why they'd do that... typically you want your difusser out far and tighter wheelbase...

See the chart at the bottom of the page:

http://www.vetteweb.com/features/0405vet_newc6/

WB is 1.2 in. longer for the C6 and oveall is 5.1 in. shorter for the C6.

whats the advantage to this

no weight hanging out in the air, i think it helps balance

typically in a racecar you want it to be longer for aero reasons/downforce.

cant really pull 3g's in the GTS class without downforce:)

look a exotics like the carrera GT and Saleen S7. LOOOONG bodies but the some have the wheels close and others far

Vipers, F-1 cars, Lambos-
all pretty big

I've been around most of these cars- and they all could easily be shortened. Whats the deal? why is GM going the otherway?

whats the advantage to this

From the previous link:

"The icing on the design cake is that the new body offers improved aerodynamics, with a remarkably low .28 coefficient of drag (the sleek C5's drag coefficient is .29). The new design also offers both reduced lift and increased high-speed stability relative to the C5."

I read high-speed stability as perhaps a tad more downforce. This is a 185 mph-capable daily driver remember. There's a big difference between an all-out racecar and a production street car as far as downforce that is desired. Few production street cars exceed 1.0 lateral g, nor do they really need to. Downforce is never free; it comes with an induced drag penalty. That's the drag resulting from creating downforce (or lift).

Even in F1, the most highly developed aero vehicles around, there is still a huge drag penalty for the downforce created. Just lifting (or declutching) a F1 car at 180+ gives about 2 g of drag-induced deceleration...before braking. Of couse they have drag coefficient (Cd) of about .70 to 1.0 depending on the track. The drag is so high that a 900 hp F1 car can be drag-limited to the same 185 mph as the C6. Of course it will get there a hellofalot quicker.

FWIW, the C6 is shorter than the current Porsche 911 Carrera. That's a first! The C6 wheelbase is also over a foot (13.2 in.) longer than the 911. Go figure.

I was expecting GM to make a more "race friendly" body for their C5R program, not go against it:)

I fully understand the drag/downforce thing.

and the C6 has reduced DF to reduce gas consumption

We will have to wait to see what the z06 specs are.
