Steeda claims it, is it real world?

Although we could ask to see the before overlayed.

Easy enough to track the frame each is listed during the video. So, I'm typing this thinking, so why aren't you doing it? 3 Days Later...maybe, leaving room.

I think that’s it.

I don't understand how anyone honestly feels a 30hp and 10lb torque increase on a car that already has 400+. That's much less than a 10% gain on both fronts.

I don't doubt these mods legitimately increase both, but I'm skeptical of whether many people actually feel a difference rsther than just justifying to themselves why they spent the $ and modding something for modding's sake.

These aren't 4-cylinder honda civics from the 90's and early 2000's where a 30 hp gain is more than 10%.

Your butt dyno needs calibrated. You can feel a 30hp change on a 600-700hp car.

 

[Junkyard Dog]

30 hp is a .2 or .3 reduction in e.t. and a 2-3 mph gain.

That's significant.

Then add another 30.

And another . . .

There are a number of drivability changes (i hope) they are making that really makes the car feel different. The extra power is nice, but the magic is in the pedal demand and trans (10R80) changes. These cars feel lazy, and lag quite a bit when you want to giddy up and go. And in the tune, you can make some significant per mode trans and pedal demand changes that really make the car feel like you have damn near 500hp. Its quite significant actually when you drive one where the tq management has been lessened or removed, pedal/tq demand turned up, shift pressures increased, part and WOT throttle shift RPMs raised both up and down shifts. There are cooling changes you can make like forcing the grille shutters to stay open all the time, not just when the car is on the brink of overheating, as well as making the rad fan come on sooner and faster. Stock cars are set to come on at 40% fan speed at 212*. Thats insane. Only when you get to 223* engine coolant temp do you get 100% rad fan speeds. And people wonder why these run so hot.

There is a laundry list of changes they should be doing to over all make this car run, drive, idle, cool itself and also run at wide open throttle better. 30hp is also more then you would get from any other mod you could do to these cars short of NOS or boost. Nothing will make as much power on its own on a stock s650 more so than a tune.

As someone who is tuned I think I can speak to this. I don't think tuned folks feel the power change, they feel the drivability change. Sure there are minor gains in the torque and horsepower realm on tune alone, but the major impacts are to throttle response, cooling behavior, transmission smoothness and shift points (if auto). So my car "feels" faster because it's more aggressive with throttle tip in and the way the transmission handles the gears. Car to car all things being equal it likely is SLIGHTLY faster than a identically equipped car, but not significantly. Now add in E85 tuning (which I have not done) and I bet it's a different situation.
At the end of the day I like to think of tuning as a drivability mod rather than a power adder. Personally, I think all cars are super tame from the factory and I like an aggressive throttle and total driving experience so tuning was the right choice for me.

Stupid question follows (and it's ok if you don't know, either): Do these cars have a coolant temperature sensor? If so, where is it?

You’re looking at the 1:1 increase, now extend that to the multipliers and you may. Even though it’s fancy math multiplication will estimate an increase that is perceptible during lower rpm use. (Kinda like when they can’t dyno in a 1:1 gear without hitting the limiter).

 

[Junkyard Dog]

One thing to add about tuning, derived only from me looking online and watching Youtube videos: There is usually a larger increase in the torque curve at lower and midrange than at peak.

Assuming this is true with your particular car after tuning, you are going to feel that much more easily driving around than the 2 or 3 mph difference in a quarter mile of acceleration.

I believe they use the CHT sensor to infer coolant temps.

 

[Junkyard Dog]

I lost track, are tunes adding 30 horsepower on 93 octane? I thought it was less.

Now E85 and a tune should do better than that . . .

Ah, dammit. You got my hopes up.

I see about 30 over stock on 93 tunes and close to 60 over stock on E85. Its quite significant paired with all the other changes. Acceleration feels effortless to 7800 on E85 and the car just sings well past 140 like it has a massive tail wind.

Makes me wonder how many laps I could get at Road Atlanta on E85 before running out of fuel.
