DONT YOU HAVE A CAR TO BE RIPPING APART

Nitrous isn't a fuel. It's an oxidizer.

Good catch

Love the new GTR.

To keep the discussion going between Hydra and Spoolin. One thing you [Hydra] did not bring up that you probably didn't even know, was heat build up. This is why a lot (not all) road racers prefer NA applications. Boosted applications create a lot more heat than NA and when in road racing can create a loss of power. This might be the reason that nitrous is outlawed in most circuits, due to the cooling effects, I don't know? So yeah, not trying to stir the pot, just kind of adding to education of Hydra.


And Garbs I love Corvettes more than you.

Yep heat soak is huge in boosted applications, then you start running into oil temp problems.

Yup, why FI will always be king of drag racing.

Ok, what was the point of your post?

wasey13

Yep, that is why the sky is blue.

You do have a point in that FI cars in general create more heat because of the added fuel they are capable of burning. And to design a Road racing car capably of managing the dissipation of heat is more complicated than building a N/A road race car.
But the extra heat is a problem that can be controlled and managed if the setup is done properly. If heat soak results in a loss of power than the design of the system was not well thought out. Which you do see at times with cars.

How about that Audi car that seems to dominate LeMans every year

The turbo diesal?? I don't believe it has won a single race this year.

You can only do so much to combat the heat. Especially with road racing if you are stuck behind someone your car is going to heat up, with FI it heats up a lot faster.

Buttonwillow is a local track, btw.

That's not true...if you can't keep your IAT's down then your system isn't set-up right. And if your always stuck behind someone to where your not getting as much flow as is needed across the I/C then you need to do one of two things
1) quit racing because you stink' j/k
or
2)Set up the vehicle's cooling system to accommodate for the reduced amount of air flow over the I/C's.

If designed right you could cool an engine on an engine stand running under full load and boost getting no airflow. It's all about how you design the system. And not everyone does that correctly as evident by cars overheating, and everything else that happens on a road course. But you can't blame turbo's as being the limiting factor in road racing applications, it's the people who design the systems that are limiting.

If something breaks you take it back to the drawing board and start over again, and take it back out and re-test it, if it breaks again, go back and do it again until you have it right. That's how we are where we are today, and turbo's can work in any kind of racing if you know how to set them up. You can't take a drag racing set-up built for 1/4 runs and expect it not to overheat when doing laps with it on a road course.

Why did you tell me button willow is by me?

Nitrous and other things like that aren't liked in road racing because of the following:
1. Unknown evaporative properties, will it be slick on the track and be a hazard?
2. Finite amount, it sure would suck if you ran out of it.
3. Still s rather dangerous compind if used improperly, hence why many are leery.

El es one

I think they use Nitrous at the track but not for racing but for drifting, I remember reading that they used it but with something electronically, I forgot but they did use it.

I have nitrous now, and wouldn't want to subject my engine to the high cylinder pressure of nitrous for long periods of time.

You're right except that Audi won almost every race it entered including that one called Lemons or Lime or something. Took em 24 hours to do it though.......

LOL,

Nice catch, didn't even see that post

It works best in a short duration period... In short moments, it can produce over 5k hp.

In tractor pulls with nasty FI set-ups and compound turbos, oil doesn't last that long!

Have you read this thread? It digressed many times into the pro and cons of different methods of power delivery and where they fit in automotive sports. I was emphasizing a reiteration of a prior contention, which, along with refutations or the introduction of opinions, is what people do on public forums and makes up the majority of the discussion... Would you like a tutorial?

BTW, welcome to LS1tech.

Cool, but it is definitely not the average engine type among the rest of the teams, which was my point.

It is a badass car.
