Get it on a dyno and get a temp gun. do a pull without methanol and one with. take notes on the exhaust temps before both runs and after. from my experience with roots style blowers is the iat sensor its self gets heat soaked while sitting in the alum manifold. the iat's that it reads after a run or a long drive arent necessarily what the engine sees in the cylinder. after a pull with meth the exhaust temp dropped over 150* but the iat's stayed the same. the temp dropped even stayed after adding 2* and an upper pulley swap. iat sensors that are placed in alum tend to give a false reading of the actual temp the cylinders see.

I have had the meziere wp136 pump under my bed for over 2 years and have been meaning to install it this entire time. I have actually done headers, cam, bigger injectors, full stereo and e85 tune since I bought it. Please post up results because the wait has been killing me!

Ok I got the pump put in and on a 50 deg f day iats peaked at 125 after a wot pull to 110mph. Before the pump change they hit 136 and climbed very fast. They seem to take a little longer to climb up and peak is lower so I would say its worth the swap.
