Anybody experincing this with thier G? Any ideas what can be done about it?

 

1% power loss per 11F increase, as the air density drops 1%.

Also summer protective software [kicks in] as fuel/air/coolant temperature increase above nominal 70F/70F/176-184F.

Move to cooler climate or redesign entire vehicle...........use less AF concentration and Redline wetter water. Larger radiator to increase peak reserve. Some way to decrease air temperature going into engine. Larger oil sump [Stillen] to increase capacity and drop oil a few degrees.

 

I'm in West Texas, so yeh, definately feeling the heat... ...as usual.

You could do the normal stuff to reduce the amount of heat underhood (heat shielding, header coating, etc.) but you simply can't negate the power loss when the intake air is so hot and thin. It sucks, but rest easy knowing that your small power loss pales when compared to what the forced-induction folks are losing when the mercury climbs. When you're N/A, you usually think you're feeling a loss (which you are). With forced induction, there's no question in your mind that you've lost power to the heat.

As I said, I'm in West Texas. We see several months around 100 (+/- 5 degrees) with several more in the mid to upper 80's. Sure, we get some cold winters (which was great with a turbo car!), but most of the time it's hot. This is the main reason I'm staying naturally aspirated with this car. 100+ degree weather is hard enough on the car without having to contend with a turbo cooking the motor as well.

Now, if I was in a colder climate... ... .

 

ehh dont complain about the 1% power loss because in the winter we may get some more power but we have to deal with snow so its not like we're going any faster anyways.

You guys dont have to even get winter setups! or screw up your rims.

 

Did I mention that I hate Texas?

Been stationed here 7 years and finally have orders that will put this godforsaken state in the rearview. As far as I know the only thing you can do about power loss due to heat down here is call the moving truck..

It has benefits (although I can't think of any) but NOTHING compensates for our 7 month summers and 5 month spring/winter/fall.

The only power loss I've noticed is the one in my a$$ when I go running outside. It was freaking 96 degrees on the airfield yesterday and it isn't even June yet.

BRING THE MOVERS! I'M READY TO GO!

 

Where in Texas, Gee?

And pratik, lol, you're right. I ONLY buy summer performance tires, usually that have some good wet-traction qualities. But we do get snow usually once a year. Sucks on those summer tires, but what are a few days or a week, right?

I sure had a blast with my 325HP turbo, AWD '97 Eclipse GSX. It would break traction at all four corners, at the top of 1st gear, IN THE DRY! I have a pic somewhere of me throwing four rooster-tails through 2nd gear in the snow.

 

Corpus Christi - where men are men and sheep are scared...

It's not hell, but you can see it from here.

 

1% power loss.... so if a G has roughly 230-240whp, u would have lost like 2-3hp to wheels

is that really noticable?

 

Per 11 degrees. So the difference between 50 an 105 degrees would be around 15 hp, if not more. Definitely noticeable.

 

Are you human?

 

Q45tech is actually the super computer that first beat Kasparov. It escaped and discovered that it had an affinity for Infiniti.

 

a turbo would help avoid any power loss

 

Yeah you guys in South Texas got it bad. North TX isn't as hot, and the price is right

 

HAHAHAHAHAHAHAHA

 

Q45tech rocks. Very knowledgeable. But a third of the time I have no idea what he's saying.
