i wanted to do installed ic pump meziere wp 136s on my lsj , my cooling mod is duall pass,cobra heat exchanger,option b custom actually i haved the bosch cobra ic pump and in wot my iat 2 jump between 6000 at 7000 to 160 but at 2000at 5500 between 95 to 140.Now i want to know if some people installed the ic pump meziere on lsj with cobra he and dual pass,optionb
or other pump and to know howmany jump the iat2.thank you for answer

 

ive had that pump on my car for 3 years now. it works fine. i put mine on originally when i did my dual pass, so it was hard to compare. i did have an issue with the pump after 2 years, i replaced a bearing in it and it was all good. in the meant time i had a stock pump on, i then noticed my iats were a little higher with the stock pump, not a whole lot. i did notice my iat dropped faster after a pull with the meziere.

is it a worth while upgrade? im still out on it. its twice the cost of a stock pump, i was able to rebuild it so in theory it will last longer. a certain vendor will argue to the death that its in inferior pump to the bosche, however i think its on even ground, if not a bit better. i chose this looking for a more reliable pump, at the point i was looking nobody could recommend anything other than stock. i took a shot and i dont regret it.

 

im tell me between bosch and meziere ,the meziere give 20gpm+ to 12v but bosch cobra give 12gpm to 16 v but thank you for answer i think put meziere if you have best result

 

iirc the bosche pump is 8gpm. yes the meziere is rated at 20gpm unrestricted, however the cooling system does restrict it down and there is only so much flow you can get through the system. the meziere pump sure looks good on paper, however without putting a flow meter in the system to actually test it there is no way of knowing. all i can say is my iat2 drops quicker after a 2nd and 3rd gear pull than it did with the bosche.

 

Mezeries stuff is top notch..... works amazingly on a lot of stuff.... like it was said above the whole system will determine flow but ive run the mezerie stuff on my drag car forever. 1 in the ice box submerged and one on the radiator. The bosch is good too though. Bosch is the best bang for the buck imho
