Dyno results (425 hp @ 28 psi) Pictures of carnage.
Few weeks ago, we attempted to tune my car on the dyno. The car wouldn't make power for nothing so I kept turning the boost up until it wouldn't run and boost anymore.
I just thought that we had spun a bearing because it wouldn't boost anymore and because there was a very loud knock in the motor. So, I finally got around to draining the fluids and pulling the motor today. I was suprised to not find any copper in the drain pan. But, I had so much crap sitting in there from before that I might just have missed it. I also did a compression test today, only getting one pulse on the rear rotor. Anyhow, I started pulling it apart.......... then found something odd. http://img.photobucket.com/albums/v2...o/DSCN3116.jpg Son of a.... I forgot to tighten the compressor housing down :lol: http://img.photobucket.com/albums/v2...o/DSCN3120.jpg http://img.photobucket.com/albums/v2...o/DSCN3122.jpg http://img.photobucket.com/albums/v2...o/DSCN3123.jpg |
haha classic!

It looks like all I need is a new compressor housing and a new compressor wheel. The shaft is still tight.
What do you think, fix the current one or upgrade to a 80mm wheel and have the current compressor housing machined? |
That sucks.

Remember , by replacing the front wheel it would have to be balance. why dont you go with th new 83mm that Bullseye offers for the BorgWarners.
Actually, some would say I don't need my current 75mm. :lol: Our local turbo shop would balance it if I decide to go the 80mm route. Still debating on doing the 80mm or spending a few bucks on fixing mine. |
Ouch! That sucks dude! So you never heard the comp wheel grinding away on the housing?

The devil is in the details. It's always something fricken' small.

jeez! that sucks! it could happen to the best (and worst) of us.
the way i see it is you'd either have to machine or replace the housing anyway. you said they'd be balancing everything, so why not just go with the 80 mm wheel? i know more is not always better, but in this case i think it could be the better option. |
Yeah, I'm thinking for $350 you can't beat it. Unless someone tells me how stupid this is, I'm probably just going to upgrade.
|
i say upgrade even if someone else tells you it's stupid. i'm cooler and sexier than them anyway. ;)

Where is this quote from? I may need this info for the future (I'm running a S475 on a 20b). Thanks!
But, I'm currently talking with paradise racing into a 80mm upgrade with the bullseye race cover. We'll see.. |

Yeah, Luis has treated me well in the past.

You going semi-pp to make use of the new turbo?
|
I'm still thinking about it. My only concern is the high idle....and if I actually need it. I mean, guys are putting down 700+ hp on stock ports. I have no business driving around with 700hp in this light of a car.
Man, it's been too hot to do anything in the garage. |

Watch from 2:10 on. Thats idling about 1200. I think with a heavy flywheel you could get a stable idle at 1000. http://www.youtube.com/watch?v=_OqpVQN_eJo&feature=user |
+1 on the heavy flywheel. I'm a fan of using the stock flywheel when having any kind of high overlap motor.
