1. This should of been posted in Forced Induction & Nitrous.

2. BUR has the stage 1 on his car.

3. If you search, you will find BUR's dyno in Forced Induction & Nitrous. Also Dyno's of stage 1 and the pending stage 2 can be found in the Focus Sport section.

Thank You for your time

 

I have the FS/VF blower on my car. All the R&D was done on my car and right now I have about 180 HP and around 150 something TQ, sorry can't recall right now.

The kit right now is a working stage 2 since FS hasn't really decided what stage 2 is yet. I love the kit though!

Also there is a guy named Steven with the FS/VF kit who was at the Fab Ford show, but I don't know if he is on FJ.

And there is a guy named Brian from SD and I think a William in the Bahamas, but Randy said they just shipped his so it will be a few days.

 

Yah Brian (8888) has it too now. I'm steppin up to the prototype stage 2 in a little bit here (after the race this weekend to see how well a stage one does at the track).

And out of the box, its a litte more than JRSC... but JRSC has power a little bit sooner. The FocusSport/VF kit comes on later, but stronger!

Here's my stage one:

comparing the JRSC (taken from their site)

 

Great info Bur. I'm ready for mine.

Give Randy a call on Wednesday and order it up! You won't be disappointed!

 

This is a better comparison. JRSC w/ FR Big Boost kit.

 

looking at the 2 dyno charts,its it looks to me that the POWERWORKS kit is the way to go...

 

Duh.

 

Yep, if you have the extra $2000 or so.

 

This is a better comparison. JRSC w/ FR Big Boost kit.

Compare the FocusSport Stage 2 to the big boost JRSC if you wanna compare apples to apples.

 

I am kind of glad I don't have the money to boost now. Hopefully when I will have the money, there will be plenty of CARB 'chargers. Randy did say he wanted to get this one approved, right??

How is comparing the BBK to the Stage 2 apples to apples?

The stage one VF kit does 7psi, the JRSC BBK does around 9psi.

The Stage one VF kit does 172whp/150tq, the JRSC BBK does 170whp/150tq.

The stage one VF kit from Focussport.com costs $2999.95, the JRSC BBK from Mcnewsautomotive.com costs $2800

So the JRSC BBK costs $104 LESS than the Stage 1 VF and only produces 2whp less. The JRSC BBK also has a much more linear power curve.

So yeah, why should we compare the BBK to the Stage 2? Argument please.

Whats the PSI of the big boost kit? Thats what I was comparing.

Dollar signs, the JR kit is nice.. can't argue that.

 

Not to mention the BBK is a much simpler install. But it is already maxed out as far as upgradeability.

 

looking at the 2 dyno charts,its it looks to me that the POWERWORKS kit is the way to go...

You know what I've noticed, that the Procharger 10 lb supercharger kit has almost the same torque/hp curve as the Powerworks kit. I compared the two charts from the Focus Fanatic Magazine and they're almost exactly alike.
I think the only difference is doesn't the Procharger kit cost 1,000 bucks less?

You noticed incorrectly... there is over a 40 ft/lbs difference in the low RPM's and the powerworks is plus 10-20 whp.

Plus I've seen others do that cocmparison. The numbers dont jive with Blox's dyno if I remember right.

Are you taking this out from the FF magazine? I've got to take a second look.

 

Those numbers are pathetic! Turbos rule!!

Wow, thanks for contributing so much to this thread. Next time the urge hits you to start typing, do us a favor and slap yourself.

The boost has been said to be around 9psi, but the person who's car was used in that dyno was only running 7psi. Seeing as the BBK comes with a 2.5" pulley and I'm running a 2.3" pulley with 10psi I would be inclined to say the BBK would do around 7-8psi.

So the two kits are almost identical in boost output and power.

Both kits have their pros and cons when weighed directly against each other, but dollar for dollar the JRSC BBK edges slightly ahead. If I had to chose between the two... well I'd need to see what the Stage 2 could do (without the race header) before really making a decision. From the looks of things the two kits have about the same limitations overall. Neither kit can be intercooled, both limited by design. Both will probably see diminishing returns after 10-12psi. I guess it really comes down to which kit the buyer fancies.

I don't like the placement of the FS charger, especially the pipe routing. That being said I don't like the smaller M45 of the JRSC.

For the money... I'd go with the ProCharger. A few issues here and there, but relatively close in price and much more potential.

Hitokiri..

Here is a procharger dyno on a very lightly modded car:
(Click for huge dyno)

From this thread:
http://www.focaljet.com/ubbthreads/showf...part=2&vc=1



Here is a powerworks dyno:

Notice the 50 ft/lbs difference in torque at 2500 RPM's. Peak torque on the PW is around 4K whereas on the Procharger it's at 5500... So there is quite a difference in power curves. I'm not sure you can trust focus fanatics dyno numbers just yet. I think they are having issues.

 

Just from the simple fact that Procharger is centi and Powerworks is roots shows that power will be in different ranges. TQ-PW, tabletop. Pro, increasing with rpm.
On the other hand, the JRSC BB Tq curve is more similar in shape to the Pro, which negates my previous comment. Peak numbers however between PW and Pro are similar. PW has the jump off the line, but after 1st gear, I bet they would be pretty even.

Not to mention the PW doesn't seem to have a lot of options beyond its stock configuration. It is already running IIRC 12psi, it's not going to be efficient past 14psi.

The PC on the other hand is supposed to be efficient up to about 20psi.

Out of the box the PW has a definite edge over the PC. I would bet the PW would pull far past the PC in a straight drag situation. In the curves the PW will definitely be hard to beat with the PC. However, after a few mods the PC should be able to completely own the PW across the board.

Don't bash me...just wondering. What would make you think that it wouldn't be efficient past 14 psi?? I think it was the vids of interviews that the PW guys have taken this kit way past production numbers, but thought this was the best tune due to fully maxing out stock internals. I would think because of the design of the IC that there is some potential left in this kit. What have the JRSC's been known to push with no IC? Even if nitrous or meth was used for aditional coooling, do you still think that 14 psi is the max??

 

The PW kit runs an A/W intercooler vs the Procharger running an A/A intercooler (under the car)

The Procharger should be a more efficient unit when you push it to the hilt. But the fact that peak torque for the PW is at 4K vs the 5500K of the procharger is quite a difference. Shift from 7K on an SVT and you hit just above 4, in the meat of power for the PW kit, still waiting for peak torque on the procharger.

[corrected] The PW kit is 12 PSI per Randys comments

 

The PW kit on our car in stock form except for our FocusSport cat back exhaust is pushing 229 HP and 185 TQ to the wheels on our Dynojet. That is with 12 psi.

And it would be great if you guys could start new threads instead of lumping all these comparisons into one thread. Otherwise good discussions and facts get lost.
