Turbo prices??

[travis]

You need to see the header that paul (Impluse) sent with my kit ! The head on my nytro will break before the header would IMO.

Hey Leroy !!

Golden boy and I are heading out for a ride on sunday are you in???........oh wait I forgot you're..... still waiting on your impulse stuff.................... to get here!!! Hope it shows up before next year arrives. Oh well the snow will be good next year as well. You can ride my M7 if you want. Hopefully you break it you've just bought it though. I've seen you ride and I know you will own a M7 in the future!!!!!! Trav
Now get back to WORK!!!!! Ya that header is nice and strong but where's the turbo??????? Ha Ha

I remember Darko's comments about turbo kits. I also remember which kit he took off. But I guess that was just his experience. I'll probably try another kit at some point but after having good luck for 4 years with several kits from the same manufacturer, it's tough to justify a switch, although I like what I hear about some others. That's what good about coming on here and TY, you can read about other peoples experiences and share knowledge, which ultimately makes it better for everyone. For guys that don't do their own work, it's very important to have something they can get worked on by someone they trust. If I lived in Timbuktu and the only dealer around sold and installed Tonka turbos, I'd probably recommend a Tonka.

You might not want to be quoting Darko, if he is jumping ship. You might not be able to keep any credibility LOL

Totally OK to quote him in that regard, even if he is riding something else this season.

 

[SLY]

Wonder how long before he's back on a turbo Yami ?

i hate you !!!!! o heres the header.

HA HA HA REAL FUNNY, I HOPE YOU HIT A TREE(Not really)

Heres the header for the Impulse race kit: Not the best pic of it but it the only one i have on my work computer.

Why does that header have 2 exhaust holes??? Whats the purpose?

Lol, The top hole is for an external waste gate..
the turbo and waste gate both use what are called V-ban clams they help keep weight down and they are super strong we use them at work they can hold back some pretty big pressure.

 

[SLY]

Looks like a pretty beefy manifold, I don't see that breaking. Good sized blow off valve on that too. I was a little surprised to see the new MCX kit has done away with the dual blow off valves and gone to a single bigger one in the end of the plenum. No price increase on the MCX kit this year but with the missing parts (mapping, fuel pump, blow off valve) I'm starting to think there should have been a $500 price decrease. We'll see how it performs compared to last year's.

Thanks for that info.. I'am getting ready to install my impulse 2871 but I was sent the other header for the 2860 is there enough "pros" to get the race header??

Well there is a little more to the kit then just the header but for most people no. I am the kind of guy who will buy something i dont need and use it anyway I have never own a boosted sled so I went with WHAT I THOUGHT was the best kit out there. I like knowing that i could turn up the boost to a really stupid amount. Paul sold me on his stuff i sold my self on the race kit.

I agree with Ultralord big bonus is the Rapid Bike box

The rapid bike box has alot of good points for sure but isn't it only mapped for 14 pounds boost with this kit??? Your not going to be doing much a ss kicking on the other turbos out there at 14 pounds when your buddy is running up to 18 or 24. And i agree with the others the hp # are a bit high for low boost, i would take 40hp from the claimed 280 hp to be more realistic.

That is the nice thing about this box! It is completely adjustable for anything. Hell I can adjust it on the hill with my cell phone. Big injectors, small injectors, different regulators, doesn't matter. I have also found that once the map is pretty well dialed you don't really need to mess with the map going up and down in boost to small degree say 4-5 pounds.

Unless you have messed with it personally it is hard to really understand how well it works. My RB3 works awesome but I fully understand how it works and can tune and make maps myself. I think most guys just want to plug it it and forget about it. You can do that with it but with a little knowledge of how the RB3 works you can make adjustments to it for your own set up it is sweet.

I have many different maps loaded into my phone. If I want to try a different map or modify the one I already have in I hit about three buttons on my phone and off I go!

I also have mine set so that I can upload/modify maps into other peoples sleds on the hill with just one connector. I can then load maps or modify maps on others sled from my cell phone on the hill.

It is the cats meow!!

 

[EZmoney]

Sap. I know it can be mapped several ways and im sure a guy like your self or my self would not have a problem tunning and learning by trial and error, guys like us are in to that. But most just want it set up and left alone. So if it comes mapped for 14 pounds alot of guys wont touch it.and i know you agree with me on that.Alot of the claims here just sound a little off 280 hp at 14 pounds? You wont make power on top with the rb3. Sap. how manny pounds you got yours mapped to??

 

[snowy1]

my understanding is the rb3 can not be mapped for more than about 16lbs, Paul tried it last year and could not get enough fuel for hi boost had to piggy back controllers to get the fuel he needed, it does have alot of good things going for it but if it can,t control fuel at hi boost 20+ lbs. its of no use for me. has anybody mapped it and got it to work at 20+ lbs.

I have had mine up to 16-17 pounds with Daves HP kit (Apex) and still have a bit of room to go up more with a 2/1 regulator at 43 pounds at idle with stock injectors.

I have larger injectors sitting on the bench and will install them as soon as I find the limit with the stockers. With the RB3 you can install the larger injectors and then back out the fuel on the bottom for drivability.

I am not sure why Paul could not get more out of it. The limiting factor at that point would be duty cycle on the injector. I know he has worked with larger injectors so I don't know why he would be limited to 16 lbs.

How would "piggy backing controllers work??

I do agree that most people just want to plug it in and go but with a turbo and all of the varibles of elevation, boost etc that is alot to ask for........... Same goes for "pump gas turbo that is reliable" is there really such an animal????????

With the way the RB3 works it is pretty consistent over a range of boost #s because it is load based off of a 2 or 3 bar map sensor.

I run a 3 bar map sensor which gives you 27.4 lbs of boost to work with across the top load bar. You can change the %'s at the top to what ever you want. It is good to have the first column on the left to be 0% so you come on the map right away. Then it is just a matter of what the map sensor is getting for boost signal and RPM that varies where you are on the map. Like most controllers by adding more fuel pressure or increasing the size of injectors to stay in the efficiency range of the injector you just adjust the map accordingly.

You can see the load % across the top. Say you are at 16 lbs of boost. You will be in the 60% load column based on the 3 bar map sensor giving you 27.4 lbs spread across the 100%. 27.4x.6=16.5 lbs

This is why as long as you have the proper injectors or fuel pressure it stays consistent across say 4-6 pounds with one map. It will not be long before there is alot of maps available for many different conditions.

Here is an example of a map. The first one is fuel. The second is IGN.

Fuel

IGN

Hope this makes sense!

I believe he piggybacked them to utilize the timing control of the rb3 with the fuel control of his other controller, and he is running 450 cc injectors, I believe part of the problem may be that with the bigger injectors you can, t up the fuel pressure as you get too much fuel on the lower end, I may be wrong on some of this I didn,t talk to him a whole lot about it, I know he said to adjust my fuel pressure at 35 psi due to the larger injectors, if you are able to run over 20lbs let us know so far it sounds like you haven,t tried that. and paul even talked to the manufacturer trying to resolve the problem and they where no help. so there is a fuel problem at the higher boost levels. again it would be nice if you can get it to work let us know.

 

[Sapling-Thrasher]

You can remove fuel at lower RPMs and still run stock fuel pressures at idle with bigger injectors. This has already been done by a few others...

I will let you know. I'm not to worried, I don't know if I need more than 20 lbs???

 

[snowy1]

I don,t know that I need it either, but I sure do like it. it would be nice to use the rb3 at the higher boost for the timing control.

 

[Sapling-Thrasher]

I actually add timing in!!!

 

[zebiraross]

I was with Paul when he tried using the rb3 at the end of last year. He was using the 450 injectors. He couldn't get more then 14 psi out of the rb3 no matter how much fuel he added on top end. This was with his Nytro though, not the Apex like Thrasher has. So he pluged in his Pure logic box, leaving the rb3 plugged in to. I thought he was nuts and there was no way it would work. Sure enough it did work and he was pulling timing with the rb3, and adding fuel with the pure logic box. He has a way of running the 450's with low base fuel pressure, and still getting enough fuel on top but I'm not at liberty to tell how.
