I will be intalling a vortech SC next weekend and im trying to make sure I have everything ready for the install before hand.....I will be upgrading injectors and have a set of 550s already..are they big enough or should I sell them and get some 650s????

Thanx

 

Also anything else you guys can think of that I should have on hand for the install would be great??? I was thinking about getting a greddy oil filter adapter and some fitiings if nesessary. I already have a defi oil press gauge hooked up to where the stock one goes and i would rather not put a T on that line if I can avoid it?????

 

How much boost are you going to run?

 

4.5" ASP pulley, should be about 10lbs of boost???

 

I am also using an AEM1052U!!!!!! for EMS!

 

I am using 750cc injectors and I am only running 7psi. I am considering going to 9 psi, and have enough injector to do so. Others may have an opinion, but I would consider going to 750cc. Good thinking on the EMS

There was a post a while back on the FI forum regarding "Post your Dyno and Mods" I looked briefly but could not find it. I would check there and see what other SC with 4.5 pulley people are doing.

According to the Post your Dyno Thread. The following people are running the following setups.

Scorpion - Vortech Supercharger @ 9psi with 650cc
Casterdog - Vortech Supercharger @ 4.3" Pulley with 750cc
GoFaassttt - Vortech Supercharger @ 10psi with 750cc
Sideways - Vortech Supercharger @ 13psi with 750cc
John Z - Vortech Supercharger @ 4.5" Pulley with 750cc

Looks like at minimum I would get a 650cc injectors, but would lean towards a set of 750cc injectors as long as your tuner can make it have a smooth idle.

 

Yeah...some steaks and beers for those of us "overseeing" the install would be good.

BTW, you'll be more than good with the 650's at 10 psi.

 

I'm not trying to make a "for sale" by any means. But if you do decide to get a set of 650cc injectors I do have a set for sale - $300 Shipped & Insured.

Other than that. I would recommend an AEM Fuel Pressure Regulator to go along with the new Injectors & EMS.

 

Most likely you will not be able to use the one with the kit. I tryed and my car just dumped gas.
