ESS 625 install advice?

I recently pulled the trigger on a used 625 kit and I am going to tackle the install this weekend.
I am trying to reduce the learning curve by being as prepared as possible. I know there are several members that have installed their own kits but there isn't really a good write up. I will have ESS instructions of course. But i thought i'd ask if anyone has any advice, tips, tricks or anything to make this process as easy as possible and remove some of the frustration.

I appreciate any knowledge or advice anyone has to offer..

Can't wait to have this thing going with the 625!

Follow the instructions, and read them through a couple times before starting. That way the process will be more familiar as you go and the "stop to see what's next" breaks will be greatly reduced. The instructions leave a bit to be desired, but if you have any experience with this engine or type of thing, it shouldn't be a problem.

I would go ahead pull the cowling, strut braces, plenum, auxiliary fan, bumper, the splash shields under the engine and the front half of the fender liners to start. You'll need to do this anyway, but the instructions don't have the disassembly all at once. At least not that I recall. It's been a while since I read through them. Overall the kit isn't bad to install at all.

milehighm3 Thank you! I do need to read through them again. At this point it's all the hoses and routing that im mildly concerned about but im sure it all comes together and makes sense.

Did you run a smaller pulley at your altitude? Did you experience some pressure drop? Ive been told by other locals here that i'll run approx 2 psi lower than at sea level.

Thanks again.

Pretty much every supercharger kit at altitude will suffer a boost pressure loss due to the lower atmospheric pressure. If you want to run the 6-6.5psi that the kit is designed to run, you will likely need a pulley 7-8mm lower than what's provided. I'm not sure what your altitude is, but we are at 6,000' and 8mm is about right, maybe just a tad less than desired. Boost pressure will also be dependent of the exhaust back pressure, so keep that in mind as well. A catless car will make a little less boost, but more power as a result of better flow.

thats very interesting as you mentioned that a catless car will make less boost, i run a essvt2 625 and i was wondering why i could never reach the 7psi mark, and now it makes sence. at redline i see 6,6.5psi depending on the weather here in south Florida.

as far as instruction, all i can remember when we did mine is, bolt the oil catch can before you actually mount the manifold, i had to go back a few hours to reinstall that. : /

I installed my VT2 kit. Hardest and most confusting part is the correct routing of the hoses. I have many pics and feel free to PM me when you have questions. ESS is also very good about answering their phone and providing real time guidance. Everything else was per the ESS provided instructions, which are very good.

Oil catch can? I would have loved for ESS to provide one. Do you have a catch can or are you referring to the coolant expansion tank for the air to liquid heat exchanger that is bolted to the manifold?

That's all I could think of too. There's definitely no oil catch can in the kit.
