Am I the only one???

My NAS 110 loves the cooler weather. Every time around this year it starts to run smoother, noticeably better acceleration, and a lot quieter.

Earlier this summer I tried a lower temp thermostat to see if I could replicate the fall/winter driving conditions but that didn’t really do anything. It has to be the ambient and under hood heat. Strange thing the 90 more/less runs the same all year around.

Any ideas why there is such a difference between the 2 trucks?

Is the change engine light on?

I ran a lower temp stat for a while. All that happened was poorer heater output.

cooler denser ambient air, similar effect to running an intercooler. forced induction engines gain excellent performance in cool ambient temps, a great but against the rules trick in track forced induction engines, ice the intercooler between runs. similar effect.

I always found the opposite with my 300Tdi 110. Whenever the temps finally got above 50, it would just get happy. Rattles would go away, it would run quieter, and shifting would be smoother. To realize the good from the cool air, the engine and transmission would first need to warm up, which took at least a half hour of driving, then you could tell the cool air was doing the intake some good.

What Caligula said. Makes a huge difference with air cooled Porsche 911 turbo's.

and Twin Turbo 300ZX's.

The only problem is your tires don't stick as well...

Ah yes, good old days a bronze colored, modified 79 911 Carrera turbo wide body with 500 Hp at the wheels, built by turbo dynamics in Glenn Burnie MD. 16x12 at rear and 16x8 front fuchs were never enough to keep it glued to tarmac at 90% throtle. endless gobs of power on cold days.

Mine was a Schwarz 93 3.6 with coil over suspension and the G50 transaxle. I was less than impressed with those guys @ Turbo Performance. Had better luck with a german guy down in Annapolis who was just off West Street in the Parole area. I was on 18's, 295.35.18 on 10 inch in rear. Agreed on keeping it glued, the lag was terrible but when it came on, it ate tires, was only getting 8k out of a set of potenza's. If you snatched 2nd under boost the steering wheel went limp in your hands, the fronts were off the ground........Maryland was a great place to own that car with all the ramps and super highways, 70,10, 50, 100 and easy access to Summit Point.

I did not commission the build, former owner had done so. it came with all paper work to back up modifications, it wore the then popular "gator backs". later, I dressed it in pirellis. tire rubber technology just wasn't there 30 yrs ago. UC you're right, I loaned the car to my best buddy for a date and he lost it and into the woods somewhere in laurel md while taking an off ramp. Yes if I got on it out of a full stop, it would pick up the front end about 6 inches off the ground.
the person who bought it from me told me he broke rear a torsion bar due to stress torque. man it was a fun car. don't know what became of it.

My neighbor is building a 77 into a backdate ST clone with a 3.3 turbo and a 4 speed. It’s probably going to be faster than my 991.2 GT3.

I thought a 72T with a 3.0 Carrera swap was strong, cant imagine the Turbos..

160mph happens fast with the 3.6 turbo.
I declined Ron's offer of the keys to his GT3 when he offered them up, knew as an out of state driver I'd end up in a Pa jail. I drove his 90 instead, hard to get into trouble with a NAS 90.
