Well, that explains it.

Another contributing factor to my poor ET and long turbo lag.

The fiberglass coating on the firewall has been deteriorating severely over the years. I took off my air filter about a week before I went to the track due to it being dirty/clogged. The day before I went to the track I duct taped the fiberglass up in an attempt to prevent any of it getting sucked into the turbo.

I noticed a more whiney noise from the turbo since I've gone to the track. I looked under the hood today finally and noticed the duct tape was missing. I immediately looked at the compressor and noticed a chunk missing off the end of one of the fins.... so the duct tape quite possibly got sucked in and minced by the compressor. I doubt all of it did... unless the turbo was really hungry.

I'm curious where the particles from the chipped fin went... and the duct tape. Car still feels great. Wonder if it happened on my final run at the track and it was quickly chopped and flown through the engine and out. Actually, the tape and whatever is probably all stuck at the intercooler. I need a new one anyway.

USE AN AIR FILTER

I might have to have my friend make me a nice tubular turbo manifold and put a new turbo on. This one is stuck to the current manifold anyway, 2 of the bolts are frozen in place and the head is rounding. I couldn't get them tightened or loosened when I had the head off back in March or whatever, so there's been a nice exhaust leak pre-turbo ever since.

Dumbass!

Go play with your LEDs!

Nah, just install the intercooler backwards, put a filter downstream from it and run it again, that'll clean it out!

^LOL!

So I have to get in touch with a turbo rebuilder and determine what it would cost to have a new compressor wheel installed.

I met with Revshift and am having them make me a custom tubular turbo manifold. Everything will be v-band connections (bolts and gaskets are the death of me on exhaust leaks). The turbine housing's flange is going to be cut off and a v-band welded on. The downpipe will also be v-band connection.

At least the entire thing didn't shatter to pieces and ruin your engine... Keep us updated!

Not yet at least.. lol

Intercooler would catch almost everything. I have a tube and fin one.

As usual, going to take this and turn it into an upgrade moment. With the tubular turbo manifold and zero exhaust leaks (currently you can feel the exhaust blowing out where the turbo and manifold meet), it should perform much, much better. Once it's all installed, I'll retune and get to the track.

one of the reasons i like s/c better than turbo...no lag
and you get response at lower rpms

[ion] C2 · 08-15-2011, 08:22 PM

Go for a ride with me, you get response. Ask alero_bmxer, he was passenger at ASS.

With a big exhaust leak and a broken fin, there's a short delay. I'd rather have lots of power at 4000 RPM and beyond than low power all the way across the board..

All i can reply to that is, "om, nom nom"

[ion] C2 · 08-15-2011, 09:15 PM

it was hungry.

and what are you doing back on here?

also a new compressor wheel is only $63 and is easy to install. yay.

Know what I could do with $63 worth of leds... Mmmmm....

Think of all you could have done with $63, if you did things right the first time

but it would look cool.

ion have you done a/c delete or any other weight reduction

[ion] C2 · 08-16-2011, 04:51 PM

a/c condenser is gone, going to replace the compressor with a bypass pulley soon. otherwise no. what is there to remove? i mean obviously spare tire/jack/tools/everything in the car is taken out, but i don't know what i'd hit for weight reduction. every 100 lbs removed is roughly equivalent to 0.1 sec lower ETs.

i'd be better off losing weight myself

Redog · 08-16-2011, 06:42 PM

^^ yeah but your a big framed guy. If you lost 100 lbs, you'd probably look sickly

xXManwhoreXx · 08-16-2011, 08:21 PM

Save up and get a billet compressor wheel

[ion] C2 · 08-16-2011, 08:40 PM

no, i'm not spending $300 on a wheel.
