Turbo project = installed ;)

[tejohnson]

Well,

For those interested, or whom actually care, I wrapped up the Turbo install this evening. I also fired it up for the first time in months, and let the turbo break in at idle for about a half an hour. I scanned the entire event, and I also got a few more pics ( and video ).

You can see them here:

Seems there is a bit of a vacuum leak, and above 2k rpm it seems to detonate... Of course the puter needs some serious tuning.

Give me your thoughts..

Lookin good Todd. I'd like to hear it above idle though... I only looked through some of the pics, but seems like a very nice buildup. Not sure about the color scheme though... Keep us updated on how it progresses!

lol, to ricey?

It was backfiring with a bit of a PING! Never changed the plug gap from stock... Needs a major tuning session.... I also have a new MAF on the way I orderd from GMPartsDirect on May 1.... Still waiting....

thats awesome! I like that you have a lot of pics. I might of missed it, I'll have to look again, but how many psi are you running?

good job on the build

[tejohnson]

I have a .7 bar (10 PSI) spring in my wastegate...

Thanks on the comments guys. Hopefully I will be able to get some major tuning done tomorrow. This evening I will be replaceing the UIM gaskets, throwing in some new plugs with a .040 gap (replacing my NGKs gapped at .060), topping off the tranny fluid, and flashing the PCM.

Sweet! Nice to see it running again. I like the comment at the end of the video too. Thats about how I'm gonna feel when I get mine done. Looks like good work though, now get it tuned and take it to the strip! lol

wow,
I really like your setup. nice a clean the first time aorund.

Nice welds LOL

Nice set up.. all though I am not a hug fan of the straight T style connectors you used for the headers.. I'd be worried about how its going to flow...

Thanks... That is why I modified them a bit and ported the excess material on one side of the Tee's. There was plenty to work with, without making it thinner at the angle than the thickness of the pipe itself. I would have love to have done more of a header for each rather than logs...

[imported_germ]

logs are better than stock, thats all that matters. and i wouldnt spend the money on tubular for a turbo setup, the gains provided are not worth the money you spend on it.


but yes, todd your setup is by far one of the best homemade turbo setups ive seen. its clean, the install is good, you took your time (a LOT of time), you had the welds done by a pro.


with that built tranny you have now, at least 10 psi, you should be one of the first grand ams (your generation) to crack into the 12's.

get some slicks and hurry up and get that bitch tuned


oh yea, im bored at work again today. our email server took a dump or something and i do a lot of work from emails.

Cool.. I like how clean the set up looks.. hope it all works as good as it looks...

[AaronGTR]

Yeah, tubular would've been better than logs, but the important thing is those logs have more volume inside than the stock manifolds so they will still flow more. It's really quite nice for such an economical manifold design. Pressure differential from in front of to behind the turbine is one of the most important things anyway, so put a nice 3" downpipe behind that and it should be great!
