Everything looks awsome that rear diff case is WAY beefier no wonder why the stock one breaks.I have to say somthing about 1 thing though.The cinder block.Rule #1 never used masonary product to support cars wood bocks are ok but that block can break without notice.I cant wait to see what it will look like.

 

Yeah I couldn't believe the difference in the diffs! I actually cracked my stock one and it was leaking like a sieve. Although, I don't think it cracked just because of the excess power. About a month ago I found that a factory bolt fell out of the brace that holds the diff into place. I replaced it, but I think the extra tweaking while the bolt was missing caused the damage.

So check your diff brace bolts even if you haven't touch them!

 

Whats the red gizmo in the pic with the cylinder and piston?

 

I think it is Blow off valve.
milos

 

Is this going to put you at 900cc then?

 

:bigpop:

 

nice!!!!!! built with good parts.

 

looks good

 

Whats with the power commander?Are you stacking and racking units?Or going with larger injectors,and boost reference fuel regulator?

 

The new Powercommander is going to replace my Dynatek ignition system and will automatically tune every split second. I can go in and set my desired AFR and it will constantly tune to keep it there

I'm running an additional two injectors (a total of 4) and I've beefed up the fuel pump and fuel pressure regulator.

I'm hoping to run the motor pretty mild since I will have a lot of practice days before the race, but still be around the 200hp mark and a 90 mph top speed.

 

i am useing the auto tune and had a lowes bag wraped around the air cleaner for 2 weeks and it still ran fine !!!!!! works great !!!!

 

Haha that's awesome! I have high hopes for this setup, especially since this race begins at 9,000ft and finishes at over 14,000ft elevation!

Just curious, it is any advantage to run 4 injectors compare to just install bigger ones in place of stock ones ? :question:
milos

Ive been told several times that smaller injectors atomize to fuel better, so imo 4 smaller injectors would be better then 2 larger injectors.

I never thought about that, thanks for the info!

Just curious, it is any advantage to run 4 injectors compare to just install bigger ones in place of stock ones ? :question:
milos

I don't think you can run enough fuel through larger injectors to get the tuning right. I've been running 4 injectors for over a year and so far I've been able to get the tuning right on.

You guys run crazy HP, which need lot of fuel. :ride: Reason I ask I tried those bigger injectors from MPI and they give me so much fuel I can't use them with MCX 3th injector, even when I turn fuel down with Dynatek. I even like to try eliminate 3th MCX injector and run just this 2 oversized ones with boost controlled fuel pressure regulator , what will happened. But again I don't run HP and RPM like you.
milos

Yeah just running two injectors would be nice. To me the more simple the setup, the less that can go wrong, but like I said I've got over a year on the 4 injectors and well over 1,000 miles on that setup without one issue and plenty of fuel.

 

I do have another Q. if I can, with this Power Commander V you can control timing too as with Dynatek or you will now run both together ? And with Auto tune, it is possible to hook AFR gauge to it or you just put another wideband sensor in exhaust ? This Auto tune really look interesting.
milos

 

I haven't installed it yet, but my understanding is that it does everything that the dynatek does, plus the auto tune feature. The auto tune unit comes with sensor that plugs into the exhaust, but I also want to continue to use my MCX display so that I can see everything that's going on. I need to do some more research and see if I can piggy back these two or if I actually need to drill another bung to run both units. I will get back to you on this.

 

doug, did you stop using the computer supplied by mcx?

 

The MCX kit doesn't come with an ECU to my knowledge. I've always just used the stock ECU with a Dynatek ignition box and tuner. If you get MCX's display, which I do have, you can use that to watch all the vitals and to also hook a laptop to and custom tune.

 

Can you lock in the fuel map easily?
I am just thinking that the auto tune is cool, but what if the O2 sensor quits working? could you exit the auto tune feature and run a standard map on the fly?
Not likely to happen on race day, but my O2 sensor quit working last weekend and had to be replaced...

 

I was worried about that as well because I will be running race gas and I didn't want it to quit working half way up the hill. The Autotune has a feature where you can set a floor and a ceiling limit. So if the sensors goes out you can set it to where it never leans out or riches up by more or less than say 10% or whatever you input. It's definitely a nice safety feature to have.

The good thing for me is that I will be going way up in elevation so I will be running out of air and not fuel

Yeah, we used to play with it, when my son had Mitsubishi Eclipse turbo.
He really like the the sound of blow off valve. :ride:
Please, post some pictures if you can, I really like to see how and where is plumbed to the MCX system. What brand is it ?
I was told to use only good quality one, which close fast after blow by to avoid suck in the dirt .
milos

before the throttle body is the optimal place, but i have seen them before the intercooler. gotta do your research on which bov to get as some leak and can cause vacum leaks. the best i ever used was a sequential by hks.

THX, actually before the throttle body will be perfect place with MCX set due long hose going from discharge side of intercooler to TB. Lot of space to put Blow off valve there on T's.
milos

That's kind of what I was thinking as well! The only thing is I hate to have it under the bed, but I will play around with it and see.

 

how much suspension travel are you going to run. would seem the lower the better but how smooth is the course??? last time i drove it it was actually quite smooth, just lots of braking ripples(this was quite a few years ago).

any way to fab some different rear suspension mounts that allow for rear squat during braking(like a car)? i would guess the geometry off of a current high end sports car would be a good place to start. gonna need every trick you've got to beat those turbo redline revolts!

 

Probably only a couple of inches

I plan on running it only about a fist off the ground. I haven't been up there yet, but it looks like they prep the dirt pretty well for the race and I know the rally cars and unlimited's are slammed to the ground. My center of gravity should be pretty low and with the XTR kit I'll be just shy of 6' wide

 

I uncle has a friend that runs it on his banshee. The thing is slammed like a pancake and really short. He actually has a shortened swing arm on it. Also the whole coarse is slowly getting more paved every year keep that in mind too.

 

Yeah it's over 60% paved now. I'll be setting the suspension up to get me in and out of the tight turns as fast as possible :ride:

 

so the race is going to happen

 

Yes sir! I got them to create an exhibition powersports class this year and I'm going to work hard to get a full blow UTV class created next year

 

on the powercommander auto tune make sure u check ur A/F before running it hard i put the autotune onmy mcx 900 N/A race engine and it never got the A/F right. after days of messing with it i just took it to a dyno to have it tuned and i think it was probobly because of the cam making turbulance over the MAF. but you shouldent have that problem because of the turbo and because your MAF is mouted outside the air system on the mcx right?

also my guess would be that your running race gas at 20 psi right? if its leaded over some time the lead will ruin the o2 sensor and make it take false readings causing it to adjust incorrectly. but once its running right you can dial down the parameters to if it does fail it can only fall outa adjustment so far but still under race conditions anything less than perfict isint good enough.

you might have allredy knew all this but i just wanted to make sure. cuz we want to see you win this thing. go get em

EDIT: i just read on and saw you allredy knew about the lead and the sensor but now you know it double haha

Thanks for the tips!

Yeah the sensor location I have now works well and I will be adding another bung there for the PCV. I will double check and make sure it's working right and since I know the set up so well I will probably be able to tell if it's given me an off reading or not.

Thanks again for the support and I'm going to do everything to the best of my ability because I feel like I'm doing this for all of you guys

 

Got some new goodies in yesterday

UTV Crap Billet Hubs





Kenda Speedracer L3RPRO's







I'm trying to find the perfect set up for tarmac and dirt and since the hill is now 60% tarmac, I'm trying to find a tire that will give me the best performance on the longest section. I found these Kenda Tires and I'm going to test them out on both surfaces and see how they do.

 

Great hubs, did you get center caps too ? They really stand up with them on open center wheels. :ride:
milos

 

No center caps, but it sounds like I might have to add those to the list

 

Colorado Springs, April 15----Fans of the storied Pikes Peak International Hill Climb received another good reason today to start counting down the days to the June 27 Race To The Clouds with the announcement that the veteran Rhys Millen will go all-out to smash the ten-minute barrier in a new, never-before-seen race car, the 2010 RMR Hyundai Genesis PM580 in his“Operation Record Retrieval.”

Millen, a 17-year veteran on the Hill, set a world record on the Hill last year in winning the Time Attack 2WD division in his Hyundai Genesis Coupe. The Red Bull driver set the new world mark of 12:09.397 last summer in the Time Attack event on the 156-turn mountain course, beating his own personal best by 22 seconds, coming home 1:23 ahead of the next fastest car in his division.

He is shifting to the high-profile Unlimited Division this year along with another PPIHC veteran Paul Dallenbach, and taking on four-time champ Nobuhiro “Monster” Tajima, who returns in his 885-horsepower AWD Suzuki

Tajima, the crack Japanese driver who holds the course record of 10:01.408 (2007), defeated a world-class field last summer in 10:15.368 that included a trio of European rally car champions paced by Ford Rallycross Fiesta drivers Marcus Gronholm and Andreas Eriksson, who may be coming back to take a shot at Tajima and the mountain.

"Breaking into the 9's has been a dream and desire of mine for the last 10 years," said Millen, professional race driver and founder of Rhys Millen Racing. "I finally have the team, support and infrastructure to put in a serious effort to go after the world record. The main focus is to be the fastest car up the hill, slay the Monster and get the record back in the family name, the Millen name."

With more than 17 years of racing experience, Rhys Millen has established himself as one of the premier rally/drifting drivers in North America. Born in New Zealand in 1972, Rhys is the son of famed rally and off-road racer Rod Millen. Rhys joined Rod in the U.S. as a teenager and soon afterwards established himself as a racer by taking first place at the Pikes Peak Hill Climb in the Open Division and winning Rookie of the Year. He won the Formula Drift championship in 2005 and the Red Bull Drifting World Championship in 2008.

Rod Millen will be testing the new car in early June due to a scheduling conflict with one of Rhys' Formula Drift series events.

Millen and his team are an ideal match to help launch Hyundai's motorsports effort with the Genesis Coupe. Millen's driving credentials include movie stunts, multiple drifting championships, a Pikes Peak world record and his 2008 New Year's Eve Las Vegas truck flip. But behind Millen's success in the driver's seat is a full team of engineers and fabricators that know how to maximize the potential of a race car.
Eleven returning champions are among 100 competitors already registered for the race, the nation’s second oldest motor sports race behind the Indianapolis 500.
The 2010 event should continue the excitement and heated competition that marked last summer’s chase that attracted 163 racers in 17 classes who attacked the 12.42 mile course with 156 turns to the 14,110-foot summit.
The popular Fan Fest, presented by Budweiser, which attracted almost 35,000 fans to downtown Colorado Springs to meet the drivers and racers, see their cars, trucks and motorcycles, and enjoy music, food and special events, is set for Friday, June 25, from 5:00-10:00 p.m.

Why arent you plumbing the blow off valve back into the intake before the turbo? keeps dirt and/or water out, even if it sticks wide open.
Good luck! Wish I could do it myself...

 

The blow off valve has to go after the turbo as that's where the compressed air is. Supposedly the best place is just before the throttle body.

Are you running race gas with that auto tune is it working good for you

I will be running race gas with the Autotune, but I haven't yet. I am going to be using straight 109 as that's the highest octane I can get that's unleaded. They should keep me from burning up any sensors.

 

Well my 2009 RZR-S is under the wrench again and this time it's being set up for the 2010 Pikes Peak International Hill Climb!

​

Below are some pics of my progress and some new go fast goodies :FIREdevil:

Are you running race gas with that auto tune is it working good for you

 

So I found a machine shop to strengthen the drive shaft and balance it last week. I should have the new and improved one back in the next couple of days. They said they were going to double the wall thickness compared to the old drive shaft and the balancing should help keep the vibration down. Here's a pic of the stock drive shaft removed:



I've also been working on getting the Dynojet Autotune installed. It will piggyback off of the stock ECU and the Dynatek ignition system. I've put it last in line so that the Autotune makes the final adjustments.



Before the Autotune:



After the Autotune - starting to get a little crowded behind the drivers seat

 

Does the blow off have a vacume port to let off pressure as soon as the engine developes vacume? if so you need to plumb it back into the intake side of the turbo or put a filter on it.

 

I believe that's the little fitting that extrudes from the top of the BOV.

 

Are you using the dyna tek and the auto tune double stacking them so you can still adjust the timing

 

That's correct. The Dynatek also allows me to adjust the rev limiter and right now the Autotune doesn't offer those adjustments.

From everyone I have talked to they say this set up works great and is the best of both worlds, so we will see

 

me and todd from hrt motorsports should be there do you know what the rules are for motorswaps

 

Since it's an exhibition class this year there are no rules other than safety requirements
