the cooler it is/gets outside, the more power/boost your car will make.

not sure if you would pick up 5 lbs worth, but who knows. a pound or two more though would be normal.

Maybe 20psi is what it should be hitting on your setup but you've never looked at the gauge before while you're accelerating. When I was tuned at around 75*s it was hitting 8psi, now at 100+* the most I see is 7psi, when it goes down to 40s* during winter I expect to see 9psi maybe 10 peak. Its all in how dense the air is, the colder air is more dense= more PSI.

If you have a gen 2 whipple that pulley combo should net you 21 psi.

 

[steveowit3os]

I would more believe, as well, that your setup normally sees around 20 lbs. You've only had the car for two weeks so it is possible you just never noticed it went to 20 lbs. before. You wouldn't see a 5 lb. boost increase in cooler weather vs. hot weather.

yea i spoke to the guy i bought the car from and he said it should be about 20 psi the way it is now.. maybe i never noticed
