it will still cool off much faster than a smooth faced disc. anything that can improve the cooling will make them better than stock. their weaknesses are that they are more prone to warping and cracking than the slotted. and supposedly the slots will remove brake dust from the brake face a lot better than the holes will.

The drilled discs were initally made to vent out the out gassing of the older brake pad compound, the modern pad have no such problem. The added benefit of the holes were that they add more bite in the ways of adding more cutting edge to the disc against the pad, which can be done with slots anyway, without the risk of adding stress riser to the disc in the form of holes.
Not all cross hole discs are drilled though, Porsche cast their discs with holes, and most carbon ceramic discs are sintered that way, thus the holes are not drilled and induces stress riser....

This is impressive for any V-6. The after-market tuners are already asking a lot from the GTR. If the GTR holds up well, in time, with these sorts of modifications, then it would certainly raise the bar in terms of how affordable performance cars should be built. Much of the current work in the GTR is already occuring without any additional work being done to the engine. This may suggest that the GTR engine design was super fortified for its stock performance numbers, and thus, capable of taking a lot more. This would be so since its engine shares a lot with Nissans veritable RB26DETT engine, which coould take almost 2 - 3 times the amount of boost it was supposed to handle in stock form, without rebuilding the engine.

I think you meant venerable, anyway this kind of ability is not unusual for a highly developed engine specifically designed to take turbo boost.Originally Posted by G35coupe
Nizpro has kits for the much more humble Ford straight six (used in some form since the 60's) that make up to 600hp on factory internals.
If you want to see amazing, check out the 997 Turbo Switzer pushed to around 1000hp on it's standard motor.
I'm not sure what you mean by the VR38 having a lot in common with RB26, apart from cylinder count, fuel type and induction method, the two are as different as engines can get.

Then you've read something I haven't read.Originally Posted by G35
Got any link? I can't think of any reason for the two to share anything specific.I read in several magazine, when the GTR was released, that it shares some design concepts with the RB26DETT and the VQ engine.
It might be tempting to try to link the totally new GTR to it's legendary namesake, but it sounds like marketing spin to me.
Heh! I read about that thing, almost makes petrol seem obsolete.Originally Posted by wwgkd
he original Sidewinder truck is the Cummins diesel Dodge Dakota rocket truck that set the FIA world record for speed on the Bonneville Salt Flats at 217.306 mph in 2002. That's quite an amazing feat, but what's more amazing is that the truck was driven to the track in Utah from California while towing its own support trailer and averaging a staggering 22 miles per gallon. The 15:1 compression, 5.9L Cummins diesel puts out 735 hp and 1,300 lb-ft of torque, and has run the quarter-mile in 12.16 seconds. The truck was also radared at more than 222 mph on the Salt Flats. Imagine cruising this thing to work every day. It still has the stock radio and air conditioning on board.

I know, I'm a pretty big Banks fan. Technology (and diesel fuel standards in the US) has progressed a surprising amount since then, too. I'm hoping he will bring this one out of retirement or build a new one like he's been threatening to do just to see what can be done today.

I've been getting interested in diesel motors for a while now, We get a mag here called Zoom and they had an interesting article recently about how you could basically just strap a small turbo to an old, clapped out diesel and improve it in almost way.
Would make an interesting project anyhow and if it blows up...nothing of value has been lost.
