    The stock regulator is at 60psi, so you should be more than fine from what I understand. My dw300c should have been enough as well for my 630cc injectors at 60psi, but alas dw pumps might live up to their reputation for me

    Somewhat small update. Everything is hooked up, set the regulator to between 40-45 psi at the gauge on the PI rail. Used a compressor and a regulator, added 10psi to the boost reference port on the regulator saw 10psi on the rail. 20 psi, same deal, so everything seems to be working as it should.

    Next up will be tuning for this and seeing where it ends up. Im going to make a post (maybe add it to the first post) with a list of all the parts I used and lengths of hose and what not. Figured it would be good if anyone wanted to try and duplicate the set up.

    Thanks for the update. Interested in how it works out. Going to be running a similar set up but with a surge tank and stock fuel pump. Keep this update as you can

    Sorry for the delayed response but the aeromotive pump supplied enough fuel to a 6th port setup with 2 2200cc injectors to make a little over 600whp on a friend's car. Same 6th port setup that I had but I used to the DW equivalent pump. I've heard better things about the Aero pump than I have about DW. I'd say that setup would be perfectly okay, like @Maisonvi said above.

    I would for sure appreciate a list since I'll be piecing mine together soon.

    hi Mate, it has been interesting reading this thread and your never ending modding thread. i put up that post on FB about PI kits and what i will need here in the uk. so if i was to buy the parts that you have listed and run it the way you have said will that work as i was thinking to go for 1000cc injectors and thought about a surge tank also. any help would be appreciated.

    Im now running 1000cc injectors without a surge tank. Is it a bad idea to have one? No. It would for sure make for a more robust system, but you dont have to have one. You can see a few posts back I posted a diagram in MS paint of how my system is run now. I can re-evaluate the fittings I used for the system as it sits now. But really if you are handy enough you can make up something.

    If you dont want to have to modify the stock tank, the surge tank may be the way to go. Im not sure if you would need to upgrade the stock in tank pump still, but at that point you are buying 2 fuel pumps.

    What are you looking for exactly? just a parts list of what I used?

    No i was reading somewhere that a surge tank may be a better overall set up, but this is only going to be my daily but have put all the parts i need to go all the way if need be. i will be the first person in the uk to do this if i can pull this off.

    I have a the v2 mani and a Aeromotive 325 Stealth Fuel Pump (P/N 11165) already just fitted as i'm getting the car forged and the car is in a garage as we speak. If i can get away with a surge tank then so be it, this can be added at later stage if i need more power. i Would really appreciate a full parts list which you have used, i have been checking on your list and done some research on what parts have been mentioned and if i can buy in the uk or will it be cheaper in the USA.

    Many thanks, could you also give any web links ? Also if money was not an issue would you have done anything differently too ? e.g going for different or better parts, if you feel you needed them.
