Hi all - I have a base S650 GT (2024) with catless longtube headers. I’m planning to get a 93 tune/e85 tune from shoemaker/wengerd performance/DRP. I’m wondering if tuning car generates more heat cos of change in timing and since I don’t have the performance pack radiator n oil cooler will it impact car?

I’d run a few tanks of E30 on the stock tune 1st, i wouldn’t be worried about that at all either.
Just don’t make back to back to back WOT pulls and don’t go for top speed runs. Nothing to worry about

??? What are you talking about?
In another post you mentioned with tuning alone we can get about 50-60 whp gains n adding catless headers might go max of 500 whp car with e85. I was quoting that.

Ok these threads are all blending together. But yes agreed. With an e85 tune over stock most cars are taking 6-8 and even a bit more spark advance over stock. And able to be leaned out a bit. E85 is like
Liquid magic with these high compression engines.

I’m new here and trying to learn.
My original question to start this thread was to ask since I got base 650 GT would that impact my car after tuning as it generates more heat as I don’t have perf pack radiator or oil cooler. Some members on group say like I’m gaining 10 whp with tuning n you on other hand say on e85 im gaining around 60 whp n with headers maybe even more?

The reality is that tuning alone is the single most gain you will get for the coyote in NA form. Nothing else will add as much power and every other mod that would depends on tuning for that gain.

I think you'll be fine with base GT. Just keep an eye on temps if you think there too high. Does E85 make the combustion cooler or something because it has lower flash point? Am I thinking that right? :crazy::question:

I think so too. I’m planning to eventually add ESS G3 but again that might need radiator/oil cooler upgrades for extra heat produced. But that’s topic for another day.

It does burn cooler in the combustion chamber, but when the car generates more horsepower, it generates more heat, and a percentage of that heat has to be removed from the coolant and the oil.

The base GT has no oil cooling whatsoever.

The base GT has a radiator designed to commute to work and the grocery store.

It will probably be fine, but if he starts tracking it or something, it is not that big of a deal to stick a Mishimoto radiator in there with a 42mm thick core if he finds his temperatures are too high.

Also, there are multiple aftermarket oil coolers out there. The biggest Setrab unit (960?) is run by the Dark Horse R race cars in GT4, so it will easily handle the oil cooling needs of a newbie on an HPDE track day. The Dark Horse oil cooler is also available from Ford, and apparently some folks here can turn on something in the ECU using Forscan that will allow your ECU to properly estimate the inferred oil temperature using the oil cooler and keep your car from going into limp mode when it "thinks" the oil is hot, but it really is not.

Umm what? You must be confusing a base GT with a Honda Civic lol. The radiator was designed to cool a 486 HP coyote and it does a great job. Lets not make silly comments.

Yes, if you track the car then additional cooling is ideal. But its not like you can't track a base GT because it will instantly overheat. The OP will be just fine.

If you cannot track the car without overheating it, then the radiator is not designed to cool 486 horsepower.

That is just a true statement.

Now let's tackle your next assertion, that
its not like you can't track a base GT because it will instantly overheat.
Maybe the qualifier adverb "instantly" was thrown in there because you realized the silliness of what you were posting when you posted it.

You are in Arizona. HPDE 30 minute sessions in July (about five of them each day, for ten over two days) are normal tourist sort of "tracking" that Mustang owners tend to do.

I'll let you tell everybody for yourself whether "instantly" was meant to exclude normal "track" use of a Mustang GT or you are actually claiming that the standard GT radiator is "just fine" for normal track use.

But, yeah, nobody is claiming the car will "instantly" overheat. 🙄

I just do not understand why some folks feel the need to bicker on the internet even when they know the other person is correct.

I wrote that his radiator would be "fine" if he wanted an E85 tune. My post actually says that. I suggested, however, that he upgrade the radiator "if he starts tracking it" and "if he finds his temperatures are too high." Which he will. You know that. This is not some wild speculative journey with no information from the real world. The stock radiator is not made for tracking. He will also need an oil cooler if he keeps tracking it, because the faster he gets, the more heat he will put into the oil. The performance of a stock GT with a really good driver is enough overheat the oil if there is no oil cooler to remove heat. You probably know this, too.
