We are thinking 13 in the quarter, maybe a high 12...

The biggest kick for me is that at 70, the throttle is barely cracked open. You are running at around 13"Hg. A very slight roll (maybe 2psig boost) pops you up to 80, another very slight roll (again, maybe 2psig boost) pops you to 90... Very un-XJish.

What you really need to see is the expression on the face of the rice grinder with his fart can as you blow him off going up the ramp onto I25.

Can't wait until I get to install mine... Most likely late summer as Sprintex is re-designing the manifold for TJs. Once we get the prototype TJ Kit in, the existing installation becomes redundant and Boostec would be "stuck" with used, parts that they could not sell. You know? My entire Jeep is made of used parts... Just sayin... OK, just hoping to be real.

At this point I can recommend folks look seriously at this. Is it cheap? No. Is it instant gratification? Absolutley. How much is it worth to you to be able to run up the passes with traffic and without problems keeping up? I am working on Boostec to become a sponsor.

The "WTF?" look is pretty priceless.

Seeing as that you guys are in Colorado, have either of you tried your forced induction systems closer to sea level elevation?

 

[Boostwerks.com]

Nope. Everything would work the same though with the turbo since the WG is based off of absolute pressure. The SC setup however would likely make more boost/power compared to a higher elevation.

Just watched the video.... How much and give to me!!!!

AH, ok. I didn't realize that there was as much difference between turbo and super charging when it comes to altitude.

 

[O-Gauge Steamer]

Any forced induction system can only work with what it has... At nearly 7,000' elevation, we get 5+psig boost. At sea level, it will be greater than 6psig of boost. It has to do with what, in aviation, is referred to as "mean air density". You simply cannot compress what isn't there. For Aircraft, the maximum take off weight is reduced for altitude, air temperature and barometric pressure as all of these reduce the mean air density. The thinner the air, the less lift it provides.

So, the upshot is, the lower in elevation you are, more power is made. This applies to normally aspirated as well as FI engines. You lose around 1"hg for every 1,000' of altitude.

Sprintex is located in Melbourne, Australia. So the system was originally developed for sea level. The additions we have added are to compensate for altitude. If you can change a manifold gasket, you can install this system. This system has been operated from sea level to 10,000'. The projection is that it will behave at 14,000' as well. Just a drop in boost due to the lack of air...

The electrical is handled via a dedicated "plug-n-play" harness. That was my great contribution to the project. It not only eliminates the need to cut your factory harness (which I really do not like) but it makes the system transportable between vehicles in the event you nedd to replace your Heep.

Wow. I saw this vid. http://www.youtube.com/user/BoostecUS#p/u

I wonder how much quicker that jeep would be with an after market exhaust system with highflow air filter and 62mm throttlebody.

 

[O-Gauge Steamer]

The stock TB is actually good up to 7psig boost. It flows better than you think...

If I ever get the SC on mine, I will run it on the chassis dyno. I have a pre run done...

Cool. Didn't know a stock tb could flow that well.

Or all of that stuff on a balanced and blueprinted stroker that's closer to sea level!

Even better. :roll:

I love it when someone throws around the words "balanced" and "blueprinted".

What I can say is...

Rick would dearly love to build a 4.7 with the aluminum head and stick it into a 2 door 6 speed 2wd. Yah, I know, they never built a 6 speed. What's your point? We're thinking we can stuff in the 6 speed from the TJ.

On another front, I am looking into building some honest to God tuned headers with a 33" to 36" 1.25" equal length primaries. This should give me a torque peak around 2200rpm to 2500rpm. If I recall my design classes... Smaller primary tubing increases velocity and the longer the tube (within reason) the lower the peak of the torque curve. I just found to formula you use to calculate "equivelent length" for the bends that have to be there. I am thinking af a 6 into 3 into one. Possibly using a flat collector for the 3 to 1.

I'm not too proud to take opinions. The tie in would be 1-6, 2-5 and 3-4. This puts the exhaust pulses at 180 degrees of crankshaft. The tubes after the 2 to 1 would have a bit of length to get the most out of those collectors.

You know, I'm actually beginning to like my retirement.

:huh: Did you quote the right post? I was just curious about how much those additional mods would make a difference on a supercharged 4.0 engine. I wasn't suggesting anything.

Once the blower gets on my 98 we will get it dyno'd. I have a Magnaflow Cat and a 2.5" cat-back exhaust. So, we will see. As it sets, I deliver a whopping 107.7hp to the ground. A larger TB would increase the response as it does the stock motor. From a pure flow stand point, the stock TB will flow enough.

 

[streetxj]

Do bigger tires affect the reading of the Dyno? Maybe that's why it's reading so low.

Can't wait to see the new numbers with the blower.

Not trying to insult, but that is kind of weak. Are you sure you don't have something wrong there?

 

[bjoehandley]

Might have more to do with him living in Colorado, altitude can do things like that to motors.
