You are running the car to 6500rpms without engine managment just because you think its ok with that filter on there. Youre doing more damage than you think. You opinion of it being safer is wrong, thats why i am in here telling you its wrong. Im not trying to be a dick, but if your going to ask for help, then ignore it, and continue doing something that many have told you not to...your asking for it.

I may not be "reputable" on this forums, and you may think i dont know anything..thats fine.

As far as being costly...dont be surprised when turbo bearings fail.

Good luck getting the car finished

Hey mate,

I totally understand now what you and others were saying about the turbo over spinning and it's clearer now. With regards to being reputable, this was not an attack on you but I was simply referring to those who have extensive knowledge and are able to offer an explanation because it's too often that people will state their opinions with no backing whatsoever and it is simply conjecture. I'm sure you know what you're talking about but as I stated, I like to have an understanding of why things would or would not work. I do appreciate the help and constructive criticism is always welcomed. I don't think you're a dick; however, the manner in which you came across seemed a bit crass but I'm over it. I too hope this works out well and will keep everyone posted on how it turns out as well as a list of the parts and prices of this kit because it was meant to be a budget build and if all turns out well, it may be the most inexpensive kit put together.

Cheers!

 

i tried....lol

 

but you could still hook up the charge pipes, not overspin the turbo...and just drive very normal out of boost at all times. Its really not hard to stay out of boost...cmon. All you have to do is not ever push the gas pedal hard. Its really that simple

 

hahaha, yes yes, I get it now! I have reconnected the piping and I am constantly watching the boost gauge! It's hard because I have a propensity and a predilection to get on the throttle and watch the boost needle climb! but in this case I'm not

 

What a frustrating read here!! At least the OP finally got some sense into him and did it right... I've never seen someone ask for help and they ignore all help this much hahah.

 

i think you all are saying that the wastegate wont open because there is no manifold pressure so the turbo will just spin spin.... right??

 

Well that and there is no resistance where the compressor is blowing since the charge pipes aren't hooked up...

 

Well, there is some resistance. It's still moving air unless you leave a cap on the compressor inlet so it can't pull in any air. Generally you'd be hard pressed to overspeed a turbo just by disconnecting your IC piping. Top speed runs would probably do it, but a quick rip through 2nd gear to 6500 rpm isn't likely to cause a problem.

 

You do realize that what you just said makes absolutly no sense at all right?

With the charge pipe off, the turbo is basically free wheeling and as said, has VERY little to no resitance...meaning its just spinning. A top speed run is no different than a "2nd gear rip" in this case because load is not a factor. Hes beating up the turbo just as bad, since the turbo will take just as long to slow down. There would be very slight difference between these 2 senarios. Only difference being the longevity that the turbo *COULD* be spun at. We really cant judge that without actually knowing how much the turbo is freewheeling...

You can easily over spin a turbo by disconnecting a charge pipe. Ive overspun a turbo before just by having a hole in a charge pipe for a month.
