i installed a JLT intake after ge a baseline of [email protected] with a 1.760 60’ on a 75 degree day with some humidity and no wind. Yesterday with 48 degree temperatures and no humidity to speak of and 20-30 mph cross wind I ran a [email protected] with a 1.737 60’. there were to other GT500’s there a base running 11.10-11.30@ 129-130 and a CFTP that was running 10.90-11.1 @130-132. This car was there the first time I went as well and had the same trap speed as me but was running 11.0-11.2 @128-129 . I would say the the JLT doesn’t make any power gains on a bone stock car. I believe that the only place it makes 25-40 whp is on the dyno due to the filter being open. I know the stock intake has made about the same increase on the dyno with the lid off. I am going to put the stock intake back on. The JLT also seemed to heat soak more than the stock intake when the inlet temperatures get up in the 150 plus range sitting in traffic or at my local tracks 300’ drags.
