Larger pulley in Winter?

[TheOtherNick]

I have herd that i should run a larger pulley in that winter due to the colder denser air. Is my engine at risk or was the larger pulley just used to gain gas mileage back in the winter from letting the car warm up. I will be putting my stock Tstat in when it gets a littler colder. Just wanted to find out before it gets cold.

Actually, it's the other way around. In winter you can run a smaller pulley due to a colder intake charge. During summer is when you may need to let up.

Thats what i thought it should be i remember reading some where tho to run the larger pulley? Thanks for the info

yeah,you definitely dont need a larger pulley in winter... but you probably also wouldnt really need to put in the stock tstat. i dont think you would really have any problems with a 180 in the winter

^X2. Even if you had the stock pulley, the colder air will help temps & kill some knock and increase the timing. I found that out last night running against a Z28 Man a dp/ubend delete/ and temps in the high 40's makes a big difference.

Too bad my jeep loves its gas. That would be a good solution to winter driving for me. I some times have to drive to school with 8" of snow on the road. I will have to scan my car when i gets real cold to see what KR is i know i have a little now. I want to see what the weather can do for me.

How does a Jeep get bad gas mileage?

 

[TheOtherNick]

I am taking that as sarcasm but i think it might have to do with it being an 89 with a 4 inch lift very aggressive tires and a carbed inline 6. My gas mileage might go up with that a bit tho i am just finishing up the install of the engine after the rebuild.

 

[Street Wolf]

Not sarcasm, I've just never seen a Jeep get 'that' bad of MPG.

Oh just look at any of the pre 1997 wranglers or the cjs and so on. The best i ever did on a tank when it was my dd was about 13.5 add a little wheeling in to it and it drops to 10 or 11.

 

[Street Wolf]

Damn, thats nuts. Makes me feel a bit better about the MPG my vehicle gets then. :th_wtf:

yeah my gtp is one of the best gas mileage vehicles i have owned. I thought of another winter ? where would be a good place to install an oil/block heater i have one that was on my wrangler. It is basically a big magnet i had it on the oil pan but the gp's have a plastic oil pan. I haven't taken time to look and am open to suggestions.

Well, I don't honestly know of any other place. But GP's don't have a plastic oil pan.

really? you really think that?

its really dependent on your setup. if youre setup good enough and you can tune it, you might be able to run a smaller pulley. i actually knock more in the winter because i make a few pounds more boost just because.

I agree with everyone, Its that time of the year to start bumping in some more timing and go and have some fun.

I must not have been paying attention to the material of the pan when i changed an oil pan gasket on a gp. I was pretty mad by the time i got it off and i thought i remembered it being plastic.
