Things to know about the Turbo xp

[Revanator]

power valves

One thing that is done on my 860 and worked for some other turbo sleds i know of, and may work for you guys. Since the power valves work well with keeping a responsive bottom end, run a line from your airbox to a T and then a line into each PV cap. Seal the cap down with silicone and just set the cap on, wait til the silicone hardens a bit then screw them down so it makes a tight seal. This will keep the power valves working properly with a turbo, and keeps up the bottom blurps and I also noticed I burn significantly less fuel.

So this equalizes the pressure and probably keeps the rave valves from blowing open to quickly? Did you just tap a brass nipple in the cap?

Yes, I used the 1/8in. threaded brass hose fittings. This allows the power valves to still work properly under boost, essentially "equalizing" boost through the motor and caps. This way the PV's move close to the way they do on a stock motor.

makes good sense, i like the idea... seeing as pipe pressure is gonna be a few psi above boost just like normal, this makes em think they are working just like they should... keeps em closed longer like they need to be to help the low end. and keeps the bellows from blowing out as at 10# your got say 15#ish pushin on the bellows, im DOUBTING they are designed for this..

helping a buddy with a t-xp project, so im loving this stuff, lots of good info. Considering there are far less of them out there, there is going to be more R&D in your own stuff as all the little tricks and tips ahvent been figured out yet compared to say the cats and poo's.

and as far as carb turbos, seems like if you spend the time to get everything right, they arent bad at all. everything turbo'd is gonna take some constant upkeep, but sounds like theres a few things worth knocking out right off the bat so you dont bite yourself in the arse.

Functioning exhaust valve's

So for the guys that are running the valves how much did this change your jetting if any?

applying boost pressure to the top cover of the rave does nothing.

Its been done 30 years ago and still does nothing to reduce the bellows issues.

when removing raves, pilots drop to 7's and needles swap to xrs as you cannot get the stock needle lean enough..

Mains drop to 270 ish and awaay we go with 2800 rpm boost...

the fuel economy is the same when correctly tuned to run valvless .


At sealevel we use 12 pilots, stock needle machined to drop another .040 leaner, 300 mains p jets at 1-1/2 ..

with shaman air to water we drop to 250 mains

Dang, Sorry to hear about your frustration. It sounds like several small things kept you chasing your tail. When everything is correct, it is an amazing animal, with zero problems. My Turbo Performance kit has been working consistant, and perfectly at 12 lbs boost. It totally rocks!!! There's nothing like a light weight XP on 12lbs of boost.
Try not to get discouraged. Do what you're doing. Everything from scratch and you will have your boosted XP to enjoy. Bryce and Josh will take you from scratch and make it work for you.

Hey guys, As for rave valve issues, the product we've been waiting for is coming soon! Mark at Supreme sent me the test set of piston driven, all machined rave valve system for testing with Turbo Performance. They solve all our bellows problems. They work perfectly! I have been testing different internal springs that pre-load the internal "valve piston" to gather data. No bleed's or boost relief to hurt response or delay boost. Unlimited boost with no bellows problems. The sled idles like a stock sled. The valves start to open at 5500 and progressively open to full open under boost by 7200rpm. The good feel of stock throttle responce and crispness is like a normally asperated sled, then boost takes it from there to 220hp, smooth as a stock sled.

cool

Thanks for the words of encouragement. Just wanted to give you guys an update. I am going to try and get this thing to work if it kills me. Got my CPI turbo pipe in. Went with RK-Tek two ring pistons. My cylinder is on it way back from Millennium Technologies. A new turbo center section showed up yesterday. Also decided to put dual EGT's on as well as the airfuel gauge. Waiting on supreme tool to get there new bullet valves done, so I don't have to worry about blowing the bellows. Also decided to put Boondockers EBC box on it. So I am hoping I can get it all back together this week or the first of next week. I will take lots of pictures and some video for you all. Here are some pictures of what my blown stock pipe did to my pistons and turbo.

I had the same issues 2 years ago

THIS IS IN NO WAY MENT TO DISCOURAGE ANYONE FROM PURCHASHING ANY PRODUCTS OR SERVICES. I AM ONLY SHARING MY PERSONAL EXPERIENCE AND OPENION!

Not to discourage you but I had many simular issues 2 years ago. Xxxx and Xxxxx were very helpful the first 3 times but after my 4th trip I had about had it. (so did they!!!!) I live in CO, so after making 4 trips back to Ogden UT. I finallly gave up on the turbo system. I spent an entire season trying to get it to work. (it never did) Take the above advice, go back to stock and enjoy snowmobiling agian. This is defiantly not a plug and play system. It starts out with a 5k system and after spending another 3k mine still didnt work. I am only sharing my experience and I assure you that it was not a good one.
Just my $.02

So much for this being an informational forum!! If you post your real opinion you will get threatening emails like this one..


hey man, i just lost 2 turbo kit sales from your post. i have proof if the loss from the email that the guy sent. according to defamation laws and slander laws, this is a just cause as long as i can prove that i lost sales. i have proof of an email.

I thought that this problem between are company and you was taken care of and now this. We tried everything that we could do to help you and worked very long and hard to try and make your sled work. All that was free to you and now this is the write up i get. i have sent all the stuff over to the lawer and he is going to look it over. You still have time to change your post if you want all you have to do is take mine and XXXX name out of it.

it is your call.

FYI
The legal defination of slander is as follows..

Good job D

I was having a hard time finding this information, so I glad your timing was impecible.

To think that a business owner, ( let alone a MODERATOR named Bryst##r ) would remove this good information is beyond me!

Enjoy while you can

Turbo Performance

I would like to hear from them regarding the issues and see what they have done to rectify or correct any further issues with reliability.

The floor is yours Bryst##er if it is ok we open this to a public discussion.

paid advertiser and moderator

yes, I also find it odd that a paid advertisor can be a forum moderater. HMMM I wonder why there are no negative posts

Good luck on this!! I hope you have better luck than I when it comes to ruffeling the feathers of the moderators, they seem to ban together and if like my case you will be the bad guy and then told by head admin to just go quietly away!!! They will run it as they(the moderators) see fit)!!! They told me that if I didn't like it not to log in!! again!! Good luck my man!!!
