I don't think this has been posted before in this way - if so, just point me in the right direction - thanks.

With this thread I have to goals - 1) get info for myself regarding trq numbers and 2) Hopefully, have torque numbers from different people with the JRSC/BBK kit all in one place.

So, if you have the JRSC/BBK (or, just JRSC kit, but preferably the combo) and you have had her to a dyno - by all means, post away. I will take you word for it, I'm sure we all will, but dyno sheets sure are a nice touch. Looking for data here - proven numbers. I'm betting I won't get more than a hand full of resopnses - gotta try though. And I don't care about before/after comparison so much - I just want to know what people are really seeing in the way of torque on our little JR products.

and we're off!

EDIT: I just realized that you are looking for SVT numbers...my bad

Here is my dyno sheet...this was with a really crappy exhaust and a two hour drive to the dyno...so there is definate room for a few more hp and lbs of tq. I have since added a borla exhaust and ported the TB, but havnt had it to the dyno with these additions. I am installing Crower stg 1 cams, and Esslinger cam gears this weekend, and maybe a 5.7" crank pulley if it gets here. Then off to FS for some tuning hopefully next weekend. I'll post up the new numbers when I get them.

Not to thread Jack, but for the money I would be willing to spend on the JRSK + BBK I'd much rather just go with Toms Stage 1 Kit, or another Turbo Kit.

In the long run it will be more expensive but at least Im not stuck with only 60 hp and 34 lb/ft of torque when my appetite for performance grows larger. If your going to save and spend the money for JRSC and BBK just save a little longer, spend a little more and get a kit that has somewhere to go and produces much better HP and TQ results.

Tom has said this a million times, HP is a braggin rights number, TQ plants your A$$ in the seat and moves the heavy pig. This holds true to no matter what engine or aspiration you are talking about.

With all of that said, the JRSC has its place in the market and does have some strong selling points...especially its price, however almost all of the boosted applications I have dealt with and the owners of those cars are never satisfied with their first boost install especially when it's a Jackson Racing or other roots/screw type charger, they always want more and our answer is always pretty much the same. Sell your Jackson, go with either a centrifugal supercharger or go turbo. (yes, there are exceptions to this i.e. Cobra Mustang etc...) Alternatively you can build your motor to be more efficient with the charger power, but if your going to build the motor why not build a monster with a boost platform that can upgrade with your appetite for more power.

Just my $0.02

We'll call it a temporary thread jack. [;)]

I really just wanted to see the numbers from anybody who has JRSC stuff - just so it's all in one place and so I can make up my mind based on data, not word of mouth. Not that I don't believe word of mouth - it's clear the JRSC is at the low end, if not at the bottom, regarding HP/TQ when looking at all the kits that are out there - I don't dispute that at all. Just looking for numbers though. Maybe other threads specific to the other systems could be started to get numbers for them in one place as well.

With 5PSI I made 211/154. I'm waiting to get tuned for 12PSI.

The highest I've seen with the standard Big Boost Kit is 227/177 at the wheels. Average is 215-220/170-175.

^ OOPS, didnt read the thread enough to realise you had an SVT, so disregard my puny pathetic zetec numbers..........

Hey, don't worry about it - maybe we should just make it the JRSC/BBK numbers thread, regardless of Zetec of SVT. Might be nice to have it all in one spot.

So - with what we've got so far, torque with the BBK installed is gonna be 170 +/-5 probably. If stock they are dynoing at around 130ft-lb that's going to be a good 40ft-lb increase, or around 33% increase. Seems like enough difference to be noticed......?

Not everyone is looking for gobs of power for the least amount of money.

Just remember:
MORE POWER to the engine/tranny = MORE WEAR and TEAR = UPGRADE or REPLACEMENT in the near future.

Your engine/tranny is not a muscle that gets stronger when you work it hard.
It wears out over time. The hader you work it, the faster it wears out.

Sometimes the decision to increase power are based on:

*Get the most power with the least amount of strain to the stock engine/tranny.
*Looks like OEM under the hood. No homemade like piping that looks like
a plumbers shop under the hood.
*CARB or emmissions compliant
*Just some get up and go power for a daily driver Focus.


Oh, and if TQ is what you're looking at, then look at the TQ numbers on the Toyota Prius hybrid.
It's like 300TQ but less than 100HP...
It may slam you in the seat but it ain't going to win any races. [cool]

Too true man. [thumb] Like I always tell people about the Jackson; you're not going to rip 12's with it, but if you're just looking for a quality kit for a nice boost in power, then the Jackson is the way to go.

^^^ see that would be more than enough for me , like some others have sadi not everyone wants a 12 second monster , it's a daily driver , 2yr/100k warranty , in a reasonable price range on top of me wokring ofr ford with the small discount , well known and reliable ,and will still be able to turn more heads then it already does....plus its CARB legal....

This is kinda what I'm lookin for also. I want more power but for me I just want to have more power and maybe a better clutch....I dont want to have to replace the D$%^ tranny because I am throwing too much torque down. Everybody wants more torque and I do too but this car isn't designed for a lot of it.
 
#20 ·
why not just save up a bit more and get the powerworks kit
after I'm done with my brakes soon, I plan on either going
the route of tom's kit or the powerworks, I dont' like
any kind of forced induction without an after/inter cooler
