This should be the driving spirit in this hobby.

 

I have a friend with a Tesla. Has the “ludicrous​​​​​​“ mode. He bought the biggest, baddest, mostest, etc. Has two Tesla’s actually. And a trophy wife...prolly worth many million dollars. Him, not the wife. Anyhoo, it’s the absolute quickest street car I’ve ever been in. AWD and instant 900+ ft. Lbs. Thing is a freaking riot. Loud laughter while in that car. It’s fun.
After the first ride, I spent a few nights researching wheelbase, and looking for a wrecked one. I was dead set on putting a Chevelle body on the Tesla chassis. Something cool, you know. Then I asked myself why. Ok I’m good. Got over it pretty quick.

 

Thats only the case when the car came from the factory with FI. I build road race cars for a living, and adding forced induction on a car that wasn’t made for it usually spells disaster. You end up spending years and countless dollars developing the car all while you could have been put driving a reliable car. Most can’t last more than 5 hard laps before they deal with heat soak issues. If it made it a full 20-30 mins, your driving is soft to say the least. Come to think of it, most modern FI cars even struggle with heat issues on track. I’ve put so many modern FI cars into limp mode on a race track it’s not even funny.

 

Just wait till those electric car drivers realize there is 170 lbs weight reduction going driverless.

 

170? I’m 215. That’s 45 more. I think your on to something here...

 

Seriously. Think about how much money people spend cutting ounces, and there is 200 lbs of *** just waiting to come out.

Driver mod just took in a whole new meaning

In B4 HPTuners figures out how to hack/tune the self driver logics....

 

Problem with Tesla's is while they are fun stoplight to stoplight they have no real top end, they are about out of steam at 120MPH. Even the fanciest ones like you rode in generally trap in the 1/4 what a moderately fast car does in the 1/8th. I would love for them to have a faster top end along with more range, I think Porsche Taycan is moving that route by having more then one gear.

I'm impressed, you must be much more talented then todays lack luster pro drivers! You should sort out all those soft driving IMSA guys that can't manage to put their boosted BMW, McLaren, NSX, Ferrari, etc into limp mode in 5 laps and end up racing them for 24 hours. Anyways I agree that factory FI cars tend to heat soak the worst, especially when tuned to above stock power levels. But IMSA does basically the opposite, as most cars make less power then their street equivalent. On the other hand, I have to beat the ever living crap out of my car to get coolant, oil and other temps even up to normal operating temp, granted I have a much smaller engine then its designed for and a fast spooling turbo to make up power as needed.

 

Re Tesla. Coolest thing I saw on motirtrend tv was a quarter mile hellcat vs Tesla 11.7@117 vs 11.8@124.

 

Are you dense, or purposefully ignorant? I can’t tell because you contradicted yourself a few times there. Who mentioned factory built and backed IMSA cars? It certainly wasn’t me. This conversation is about forum members, the average enthusiast. The fact of the matter is, adding forced induction to a car for track day use is a terrible waste of time and money. It’s great for a fast street car or a drag car, no arguing that. I was simply supporting a point made by another poster regarding a situation where adding forced induction doesn’t usually offer any benefit to the user. We get it, you love turbos. So do I. My daily has forced induction, and it’s a fantastic car. But years of experience building, maintaining, and tuning cars in Grand Am, IMSA, World Challange, Trans Am, SCCA and NASA has taught me that forced induction ends up usually being a headache in road racing situations unless your budget is unlimited. Isn’t the goal to have a reliable car with a reasonable budget

By the way, all of those cars are based off of cars that come from the factory with forced induction, which was my point. Not to mention the manufacturers spend millions of dollars developing them into endurance race cars. Is that practical for the average enthusiast?

 

Ya I think the fastest Tesla I have seen is 10.4@124 but that's full Ludicrous P100D, weight removal, drag radial, etc and costs $115k+. If you show up to the track with most cars that cost $100k+ or even $50k they certainly won't be running 10's and the Tesla gets gapped.

If they can ever get to a point they can match a gas cars range, say 500-550 miles, recharge in the same timeframe as a typical gas stop, and not have a substantial price penalty then I may be interested. Until then there are too many issues, look at what happened during high travel periods on the East and West coast. It took some Tesla owners 12+ hours or even multiple days to travel what a gas car would typically complete in a few hours because charging stations were backed up with lines, the cold weather substantially reduced range, etc was a recipe for disaster.

 

Chill out cupcake, IMSA was an example because you said you could break anything in 5 laps. Plus the Ferrari isn't factory backed, but you know that since your such a pro at road racing. Really no type of racing is practical, it's pissing away funds for zero gain for 99% of people.

 

Can you point out where I said I can break ANYTHING in 5 laps? Oh that’s right - I didn’t. What I said was a pretty simple statement - I’ve driven many factory forced induction cars on a track that have gone into limp mode quickly. I never stated I was a pro driver, I’m quite average. If you spent any time at the road course like you claim, you’d notice other novice drivers dealing with the same issue. It’s a very common sight. Not exactly sure why you make things up to start pointless arguments, but judging by your interactions on this site, it seems like it’s your typical M.O. Maybe your reading comprehension is just severely lacking, maybe you just enjoy fabricating things to suit your narrative. Not sure at this point. You say some pretty intelligent things that lead me to believe you have a lot of experience building fast cars, then completely destroy it by creating arguments that weren’t arguments in the first place.

Again, not sure why you keep bringing up IMSA teams? Really has nothing to do with the conversation. Since you decided to bring up the Ferrari - yes, Risi is no longer a factory funded Ferrari North American race team like Wright Motorsports is for Porsche. However, they still do receive engineering help from Ferrari and share data amongst the other teams around the world that campaign the 488 GTE. A car that wasn’t built or developed privately. Also, a car that comes from the factory with forced induction. It’s a car that Ferrari developed and shouldered all associated costs, purchased by Risi. So again, massive amounts of money spent on the car by the factory to ensure it’s reliability in endurance racing.

I will give you that forced induction is very popular to make big power in time attack builds. Pretty much every competitive time attack car runs huge power turbo engines. Highly effective, however the cars are designed with limited cooling capacity to keep weight down, and only do 1-2 all out laps at a time before they run into issues with heat.

Of course racing is pissing away money, no disagreement there. It’s a contest to see how much you can spend, at every level of competition. Everyone has a hobby and deserves to enjoy it. Some people have bigger budgets for their hobby than others. This site is full of average Joes coming to learn more about their passion. If one of those people was thinking about building a car they planned on tracking and they stumbled on this thread, they would see some bad information regarding forced induction for road course use. I was simply trying to explain and support another poster in agreeing that there are a few situations where building a naturally aspirated engine would have an inherent advantage over a forced induction car. It was nothing more than that. You decided to fabricate an argument and narrative that wasn’t really there in the first place. I don’t think this warrants any further distraction from the original intent of this thread.

 

So many words... get your shorts out of a bunch, go work on a car, chug a beer and calm down lol

 

Typical response when you can’t form a cohesive argument. Sad.

I was hoping for a challenge but you disappoint us all once again.

Here comes SLOWSEDAN aka DEFLECTO-MAN!

 

I'm not sure about the USA but we have this intercooler called an interchiller.

It's a patent pending design which has had huge success down here but the kits are super expensive.

Once the intercooler fluid passes through the chiller it is supercooled to below freezing temperatures which then lowers your intake temps of your water to air intercooler system of a supercharger or turbocharger. The interchiller can be fitted to any car or truck as long as the car has a water to air intercooler system (supercharger or turbo charger) and an AC system. It also has no limitation to HP, it can deal with it, so far the biggest build it has been involved with has made 2400HP. You are able to hot lap the cars at the track back to back with the same consistency every run, by the time you collect your time slip you are back to your minimum intake air temp and ready to go again.

The new BMW M5 with it's twin turbo v8 suffers heat soak also.
On a 32 degree celcius day the engine only revs out to 5500rpm in order to deal with the heat.
And the fans still operate after the car is turned off.
To design a really efficient cooling system would be expensive and also, the engine bay has hardly any room to move in those cars either.

 

From what I've read, it is great for the drag strip, not so much on a road course.

 

From what I have read they also work very well for the road course too.
They are used down here also for that purpose.
So you guys don't have these kits in the USA then?

 

I had that set up on my 3.4l whippled ford lightning. Kincaids Killer Chiller system. Workd great on hot days while drivn around with AC on. Track didnt like it even in staging lanes, thought you were leaking and would continue to do so down the track. But defly a must have for blower cars. Problem with turbo builds, most are A2A intercooled

 

https://killerchiller.com

A2A intercooler systems are simply easier to package, and most importantly apart of the much larger turbo picture of budget oriented. A2A is KISS method, cuz it works for majority of intended use.

 

Putting a big blower on most things is the easy part, spending lotsa time n money on the supporting systems/mods is where it snowballs. NA gets like that too after 600hp,...excuse me while i go eat my Ramen noodles for lunch! Lol
