Does anyone have or know of someone that has the JRSC w/BBK plus the focuscentral boost kit? If someone does have that setup what kind of pwr #s are you getting and what other stuff would I have to change to make it work? Thanks for any info ya'll can give.

what is the difference in the focus central boost kit?

I have a feeling this thread is going to get moved to Forced Induction Chat lol

it seems to me that it is a crank pully that is bigger than the stock one so that for every revolution of the crank you get addtional spin on the subercharger crank. so basically it is like similar to a smaller supercharger pully for addtional boost

I'm wondering how much more power I could get by adding the two together. Smaller charger pulley and bigger crank pulley.

Are you psychic? LOL!....Moved. [;)]

well according to websites you should be seeing about 5 poundes more of addtional boost if you ran both. but after reading focus centrals website you may need to do more engine work such as bigger injectors and probably a different tune

^^^ LOL Yeah, I was in the zone earlier today, and now I can't even find it much less get back in it LOL

Well with the BBK on the JRSC kit shouldn't those upgrades and tune be good enough to cover the crank pulley change from the FC kit? The FC kit adds 15 whp and the BBK adds something like 10hp I think, I would think the tune and injector upgrade from the BBK would handle both. I just don't want to do too much extra work to add the two boost upgrade kits together you know.

I would not recommend adding any more boost to the BBK unless you are going to spend all your time in high altitude. Otherwise you are asking for problems with a perfectly good tune as it sets.

A custom tune can get you closer to the edge of performance/disaster than the tune we put in the BBK. The BBK tune is perfectly safe in all weather conditions. You might be able to make a bit more power with a custom tune but you run the risk of problems in less than ideal conditions. But then you can just adjust the timing maps back again. The BBK was designed as a plug and play product for those that don't want to tune.

If you are willing to get a custom tune to your ECU adding a couple pounds of boost to what you have by adding the overdrive crank pulley is worth trying.

No the BBK form Ford/and jackson is not going to work if you get the crank pully from FC you will have to get a custome tune
