Bad reeds on xp turbo

vadnaiskid · Jan 17, 2010

So How do i know if my reeds failed in my Xp I can only make about 5psi of boost and the sled will only tack to 7700 on a climb and My knock sensor is going off some times my egts are 1150 to 1200 I have no exhaust leaks that i can find

i would check your reed boost over that happend to me last year had a hard time finding it thats wherei would start

at idle if the reeds are blown apart one cyl will be colder at idle, and sounds like you've got a boost leak somewhere

You need to figure out why your knock sensor is going off first. I don't think you have a reed issue but there is no doubt something going on. Address the knock sensor issue first.

"no exhaust leaks that I can find"

have you presure tested it? My pipe had a crack on a weld and I looked at it once right in front of my face and did not notice it. Looked at it a second time and just noticed a little discoloration on the pipe from the exhaust coming out and then noticed the 12" long crack right on the seam.

if this is the case it should not cause your knock sensor to be going off though. Might be a different issue then the pipe or something else being cracked of you might have a couple different issues.

I am going to take the sled apart tonight to check the intake side and the pipe It has to have a leak some were. I think the knock thing is comeing from being way way to rich It has been getting better the more i turn in the jets I think i am at 1 turn with the pto side and 1 1/2 mag side with 380 mains

knock senor issue I have seen, guys cut out a small peice of paper and put it between the knock sensor and the head. Seemed to help stop that issue but will stick pick up real "knocking"...

Im currently testing out my aluminum intake boots i made , and am having good luck so far. found a couple of companys to produce them for me. All because of your same issues your having . Also i like to take boost from the reed side for the blow off valve. When you let off the throttle you get vacume, in return dumps boost imediatly, thus no run on.

Sledrush, have a look at turbo performance website or call Josh they have a fix for the boots.http://turboboyz.com/store/catalog/product_info.php?cPath=257&products_id=771

Check your carb boots on the bottom side and around the bolt holes.Mine split where the rubber meets the internal metal frame/flange.I have a feeling that this is going to be a very common issue just like previous years.

Thats good to see that Dave and Jake are taking care of some of their customers. Maybe next time you talk with Dave ask him where my money is? Not to happy with funding their business.

Sweet man thanks!Before I even went to lunch today,Dave called and told me that he had seen the thread and Jake had a set of their own coming my way!Not stroking those guys,but if that isn't customer service,I don't know what is.Thanks Dave and Jake!!!

damn... That sucks. Something come out of the engine or go through the engine?
were you not runing a filter or any kind of screen?
I don't have room for a filter on my xp. but I put a screen over the intake so nothing big can get in.
I run atleast a screen on every thing if their is no room to put a filter on. I have only ran without a screen a few times at the dragstrip because I took my filter off.

That is the exhaust side Freaking skidoo popped a ring. When it popped a ring i looked in the turbo But could not tell it had been damaged I had to take the turbo apart to find it.
