so im fairly new with the ss and i hear alot about the option b and the dual pass endplate.so iam wondering what are they?what do they do?how hard are they to install? and for the record i have the zzp stage 1 heat exchanger on the car.

 

dual pass alows you to run 2 h/e cooling mods pretty much its alot better than stock if were running small pulleys and bigger injectors.

its all pretty much to do with cooling

 

ya im running zzp stage 2 kit on my car right now.how hard is it to install?

 

option b is cake never installed dual pass to be honest.

 

so option b would be my best bet in your opinion?

there is the diagrams of it

 

The dual pass. I helped a buddy install it's not to hard but does lean towards being a pain you have to take off the S/C and the intake manifold and there is one bolt that is a ***** ended up removing the alternator to get a half inch of extra space. Check the how to section there is stuff there on how to do it.

 

the dualpass refers to the endplate. the cooled coolant only passes through the laminova cores twice. you can run the option b and dual pass endplate with the stock h/e if you like.

The dual pass endplate was a bit of a pain since taking the supercharger and everything out. the endplate itself is only 5 bolts I think.

It's just tedious and time consuming taking everything off and making sure you get it all back on

 

what is going to give me better gains though option b or dual pass?

 

option b just allows a little more coolant to be held in the system as opposed to the little filler neck.

The dual pass endplate cools the compressed air and allows for a better burn of the fuel for more power. I did both at the same time since i added a second heat exchanger and was gonna have the front end ripped apart in the first place

 

and can i just run option b without the dual pass endplate?i do have thee zzp stage 1 h/e on the car

 

ya you can. the option b is just a larger coolant tank for the intake air cooling system. Normally when someone does the dual pass they do the option b as well. It also makes bleeding the system of air alot easier.

Had all the air out of my system in about a day or so

 

is it worth it to do just the option b are there any gains that would be noticeable?the reason im asking this is because i plan on gettting the car tuned in a month or so and i want to get the best numbers i can.

 

thee is tons of info on this topic, my reccomendation is a flothru option b.. it atully adds more fluid to the system. google vulcan turbo or something and they have a link on thier site for cooling mods. definately get an optionb

 

if that's the case then get the option b with the dual pass. you will notice a bit of a difference once installed and bled of air

 

i would do both

 

I just made a thread for info about the dual pass.

 

yeah i wasnt payiong attention too much when i was typing.. but yea do both at the same time. like everyone else said
