Edelbrock E force 5 to 7 psi upgrades?

I've had my supercharger for a couple of months now and want to upgrade to the 7 psi pulley which just arrived today. I was wondering what else I would have to upgrade to make it all work with the street legal kit.

Will my stock fuel pump be sufficient or will I have to get a boost a pump or a gt500 fuel system?

What gap should I run the spark plugs?

Should the belt that originally came with the kit be the proper length?

I have the factory air box and have the cai kit ordered, but would the stock air box work with the 7 psi kit?

The stock fuel pump will not be enough for the 3.5" pulley. I would recommend the GT500 pumps over the BAP. I run my plug gap at .032. You will need a shorter belt also. With the 3.5" pulley, I use a NAPA 061031 belt. You will also have to go with the Competition air intake which includes an upgraded MAF or equivalent. Also don't forget about your tune, it will have to be adjusted for the new set up. Good Luck with your upgrade. You're gonna love it.

I just got back from the track a few hours ago. With the 5psi kit and borla headers and magna flow catback, I managed a 12.6 consistently. I can't wait till I get the 3.5 inch pulley in order along with it's requirements.

As far as the fuel pump upgrade, I think I might go with the BAP. My only question is the effects of longevity of the stock pump?

Will there be tuning issues with the BAP? Like idle issues?

How do most tuners recommend the BAP be operated? Full time or boost switch? Any help would be appreciated.

I use a boost a pump with my 7psi Techco along with the stock plugs. Chris Rose tuned the car and did not say anything along the lines of it not getting enough fuel or the spark blowing out at high rpm, so I have not changed either. Thats not to say the GT500 pumps are probably a "Safer" choice and cooler plugs are most likley worth some horsepower. I turn my Boost A Pump down for everyday driving to help with any theoretical longevity issues. Turn it up when Im at the track. It all comes down to $. If you can do the better upgrades, why not?

I am not sure why there a lot of people against the KB BAP. Also KB states thier BAP is easier on the stock pump. Not sure if thats just marketing or not. But I can say I have never had an issue with mine. The car idles smooth with my AF ratio is right on the money under boost. It is wired full time not using the boost switch. Keep in mind there are many other factors on how the car idles - tune, plugs, etc.

I now have the 3.500 pulley and the cold air kit. I am currently waiting on napa belt, boost a pump, and SCT tuner with a custom tune for all including longtube headers. Also waiting on aeroforce gauges.

All parts should be here by the end of the week. Friday is another drag event which I plan to run. Here's hoping

BTW I have an autometer vac/boost gauge with the triple gauge pod already installed, Now everytime I look at the two empty holes in the dash it reminds me of how much it can suck trying to get parts up here in Canada, lol.

Congrats JimmyTango! I have the 7psi pulley and the Edelbrock CAI but I think I am going to wait til my car becomes dull. 408RWHP & 409 RWTQ is good enough for 11.9s and I want this car to last at least another couple years.

I had put all the parts on Friday night as soon as I received my sct tuner from Brenspeed. It took me about an hour to change pulley, belt, CAI, and finally load the new tune... I love the throttle response that the Brenspeed tune had given me! I now have to relearn driving my car! It's so snappy.

It took me a few passes to get my 60 ft back to normal at the track, before I was launching at 2500-3000 but now if I try anything over 2000 rpm it will just spin.

Oh and I ended up with the kenne bell boost a pump and routed the cable through the car and mounted the dial in the glove box. I can post the pics up of the install as well as the dual aeroforce gauges and boost gauge.
