And it might be sold again without the SC of course. This kit has my attention.

 

Your 2899.99 dollar kit doesn't make much more horsepower then my 197hp 218 ft/lb torque I had with Headers tune exhaust and intake.... Maybe for the price you should throw in an Xcal with custom tunes so you can actually make 250hp.....

 

@Ranger093
Thanks for your comments. You're right... just a basic tune after will make a lot more power!

Regarding tune... we have teamed up with LaSota Racing of Ohio and we will be providing add-on packages with the new X4 SCT Tuner. We will have this kit making a lot more than 250 when we are done.

It is also important to note that our kit is 2899.00 MSRP. We often drop the price to $2000. We also throw in a lot of pieces such as an intake kit (with heat shield, conical filter, etc), 255lph performance fuel pump, quick change pulley kit (6pk pullies that fit your belt and don't slip) and countless other goodies (emblems, etc) which makes our kit the cheapest on the market... we also boast about the extreme level of detail and quality of our CNC alumimum parts... not to mention our kit's compatibility to our intercooler kit and other upgrades.

 

Any word on the release of the intercooler kit? I think I had read somewhere you were aiming for March, but not sure if that's still the case.

 

Kit seem awsome! Posted it to my own ranger forum (from Québec, Canada), Maybe get you guys a couple of sells (maybe myself :P)

Hows the kit for an '11 off-road rig?

 

@timbits588
The intercooler kit has been taking longer than expected. Due to the custom nature of the CNC headers and the requirement to have them separately welded to the radiator core, there have been some unexpected delays. We have all the parts for the intercooler kit in-house except the IC (pumps, overflow tanks, wiring, hardware, etc). We expect the IC kit to be ready for sale by the end of April. We apologize for the delay. Good news is we will also have Mustang 2005-2010, Explorer 2006-2010, Sport Trac 2006-2010, and early model Explorer & ST out by April 30 as well! So to say the least... we have been very busy. More Ranger accessories and parts are coming soon too!

@ianyboy
Thanks for the post on there! We've actually sold a 2 kits to Quebec so far... so beware... there are at least 2 fast Rangers in your province. Thanks for all the support!

 

There's two fast Ranger around here, and they ain't on my forums yet, that's a sin

Oh, and no worries for the post, it's a pleasure!

 

Got my Kit installed Sunday, and aside from a few minor hi-cups, poor contact on fuel pump connectors and a tick from the seam in the drive belt, everything has been great. going to run the 3 psi kit for a while to work out the kinks then do some tuning and up the PSI with cooling of some sort.

the install has its challenges but is very well thought out and strait forward to install. even for a weekend tinkerer like me.

 

Any updates? How is it so far?

 

I'm out of town right now but I have out about 150 miles on the charger and it seems to be running great! Defiantly a noticeable power difference. I will update as I get bugs worked out and get more miles on.

 

How long did it take to install? How does it run w/o a tune?

 

If I'm reading correctly, is a custom tune not required? Certainly its recommended?

 

All in all it took me about 12 hours working very slowly and deliberately ( I did not want to mess anything up)

It runs great with the 3.0psi set up with no tune the stock ecu has had plenty of room to compensate for the added air.

Correct no tune required the stock ecu learns and compensates well enough. I will eventually have some tuning done but it's been great to drive as is!

Drove a bunch today and the added power has been awesome truck does not down shift up hills nearly as much.

 

That's great. Any idea why a different fuel pump is required for this kit but not the rpcaster?

 

Not exactly sure to be honest, obviously it's for more fuel flow when needed. My idea is the moddbox and rp caster both need the extra fuel, rp caster does it via the fuel rail kit, modd box used a high flow pump. Same result just different method

 

@mikerider
You're are right. We included the fuel pump in our kit because more fuel flow was needed... but there is a bit more to it.

We don't want to get over technical here... but we really don't want anyone to blow their engine. We also want everyone to know why you MUST upgrade the fuel pump. Anyone who is doing their own custom setup or running competitor products should be aware of this.

Even the stock naturally aspirated replacement pumps have a difficult time keeping up with the fuel flow and maintaining 65psi at the fuel rail at WOT (whether or not the rail is looped). When supercharging, the higher fuel flow drops even further and any stock fuel pump (even if it's brand new) will not be adequate.

Regarding fluid dynamics, pressure drop is relative to the velocity of a fluid and the friction of the wall (if interested.. see Darcy-Weisbach or Hazen-willilams). By simply looping your fuel rail, you will not achieve higher pressures at your injectors because the flow through the looped linkage will be almost negligible (therefore your pressure increase will be negligible). In fact, the only flow that might occur across a looping linkage would be the flow that is equalizing pressure across the rail. Since the rail is almost identical in length, shape, and orientation, this flowrate is calculated to be zero.

See illustration for clarification (Q = flow delivered by pump):


Something else to consider, is the fact that introducing additional bends, fittings, orfaces, etc will only further reduce the pressure at the injectors from the stock setup. The only conceivable reason to replace the fuel rail is the fact that you cannot fabricate a square plenum and utilize the stock rail or mounting points.

The most cost-effective and practical solution is to increase your pump capacity. This will also ensure you system will be setup for higher boosts in the future. Trying to tune your engine to a pump that is loosing pressure at the rail will not perform well and it will lead to premature failure of your pump... and you will ultimately change it anyway.

Hope this helps.

 

Gotcha the dynamics of the system defiantly warrant the larger pump and over all I feel it is a better solution. The upgraded loop type fuel rail does allow for a higher volume of fuel directly available to the injector at Wot but this only would help for a short period of time until the supply is diminished. At that point the engine has the potential to lean out.

Reading what your saying and reviewing the diagram it's a little over simplified, if the rails are matched you are assuming that both rails are equidistant from your source Q. But as you said fitting and line length change your apparent pressure in the system so your more likely getting slightly less pressure on the passenger side fuel rail.

Either way if your capable of delivering more flow to the system then it ultimately demands your in great shape.

I am working toward doing some data logs and would be very interested to compare the curves generated by booth set ups.

Oh and please do get overly technical! I am a mechanical engineer (composites) And love to know the details behind why things are done a certain way.

 

I guess we have two engineers in the building. LOL. Maybe we can geek out on here with some conservation of mass and conservation of momentum derivations. :)

Although your statement quoted above is true to some degree... the "short period" is probably like a millisecond. Remember, fluids are considered incompressible in fluid dynamics (unlike pneumatics). The added line length to the passenger side (~4-5") does make a difference... but that same length would be essentially added again with the "looped linkage" at the other side (granted the flow would be almost 0 across this linkage so they headloss/unit length would be less there). We are definitely splitting hairs now. LOL.

PM our account if you would like to get more techy. People might start unsubscribing to the thread! hahaha

 

.

I'm splitting hairs, it's nice to have detailed discussion on the forum and like I said I like to know the why behind everything I do to my truck.

This is a good information for others considering the kit. It all comes down to meeting the fuel demands of the engine. And a fuel pump is a cost effective way of doing that.

 

Great info guys!

 

Thread Edit: Fixed video link

Added 8psi dyno sheet. We actually have more products coming available to make a bunch more hp :) (10% smaller pulley, engine pulley swap, intercooler, etc. This was also done with only an aftermarket exhaust so there are lots more mods you could do to get more like headers, CR ratio, cams, CAI, etc)



ps. That's already +8hp & +23lbft over the Mustang GT :)

 

Awesome can't wait for the inter cooler to come out!

 

I'm leaning more and more towards this swap. How willing would you guys be willing to work with a built motor? I'm considering building up my motor using Tom Morana Racing and would like to pair this swap with that build.

 

@01RangerEdge

Thanks for your interest. We suggest that 8psi is as far as you should go with the stock internals. Sooo... a built motor with a few tweaks would be lots of fun :) Ready for >300rwhp? LOL

I just had a quick look the Tom Morana site, if you are swapping some internals, I would change the pistons first and lower the CR. The Forged Stock Replacement Pistons/Rods & crankshaft combo would probably be the ticket (I'd have to look into the crank shaft in more detail though). Feel free to PM me if you want to discuss any specifics.

 

This is looking awesome, I am really considering doing this to my 04. Do you guys sell a tune separately for the 3.5 or 5 psi pulleys? I would really like to put the 5lb one on if I could get a tune for it.
