Your right, there is something to do with the large exhaust pulse. When we went to the gt15 from the TD04 we had to lean it way out just to get it to run half way right, right then we knew the...

It was nice talking with you Ike.

Thanks
To be honest I'm really not set on a larger turbo, everything you have said about the gt12 makes scents to me. But the only change made was the turbo, so if I knew nothing about nothing I'd...

Sorry its been so long. First Kirk I do wanna say Thanks for all your help and I'm not trying to step on your toes with where I went with this build. Again I really appreciate your help.
Just a...

I do, I've been meaning to give an update just just busy at work. Give me a few days to get back on here.

Well again Thanks for all the help, I'm keeping an ear out for a used gt12. I agree with all the dyno bs posting. It makes it hard to know whats what.
Well I need to head out to work.

I noticed the gt12 has a 1-1/8" turbine inlet, thats so small its hard to believe a motor a breath threw that? The Cdale motor has two 1-1/8" pipes that join into a 1-3/4" pipe. Should I run the two...

Its an ATV Dyno, we do 5th gear/top gear with tall gearing,something like 90mph.
I'll go with 1" charge pipe http://fsae.com/groupee_common/emoticons/icon_wink.gif
The Cdale has a air horn from...

Let me try to make sure I answer everything.
I have 2 Td04's I've played with. Lets stick with the 9b for the current set up.
I ride in Pismo most times.
We dished out a stock piston, there...

Thanks a TON!! When I see the math using my numbers it all clicks. I have only seen compressor maps for the Td04's. I've been told/read on a single its about getting rid of the big exhaust pluses...

I've seen that video. That bike is a 575cc I'd guess he's around 75-80hp N/A.
Mine's a 432cc with a ported head,puts out about 50-52hp N/A I know my head will support 65hp on a 505cc N/A. A few...

The one with 75hp is a Td04-9b from a 3000gt, We would like it to spool sooner.
The 2nd one we have is a Td04L-13t from a WRX,at this time its a bust. Wont spool soon enough.
I'm not a master on...

You can run your drain right back into the top of the oil tank. If you Google Yamaha 700r turbo you'll see some pics.
I dont own a 700r but they tap oil right from the oil filter cover, its my...

I'm sorry its 11.5 lbs of boost not 13lbs.

Hello, right now its putting down 75hp, and 41ft-lbs at around 13lbs of boost. We ran it w/out the air box and it still put down 75hp but torque was down to 38 ft-lbs and the power curve w/out the...

I just wanted to give this an update. I've sent the motor and turbo to my builder in Pa. I was able to talk to a Yamaha turbo builder in person witch was very nice beings I"ve never seen or talked to...

I wanted to give you guys an update. The turbo I had on there turned out to be way to small, the bike just wouldn't rev past 8,600 rpm. The exhaust side was just way to small, in the end I lost a...

Thanks. As with most projects they always take way to long. In one hand I hate a 6 day work week, but in the other it lets me afford the project. Thanks Again I will keep you guys posted.

Its uses the GP Control SAGEM MC1000 ECU. I can change everything with it, fuel, ignition,reset TPS, and more things then a person should be able to mess with the only thing I cant do with it is Live...

I'm in Hanford, about 45 min south of Fresno. The $350 if for fuel tune only no ignition. That was also a none turbo motor, so I'd guess it'd only be more with a turbo?
The motor has a stock rod,...

It's EFI. I'm using a Zeitronix Zt-2 data logger. My waste gate is set at 8psi. Thats funny you said I'd need about 15psi my engine builder said he thought I'd need about 15psi as well.
I do agree...

At this point, I cant say I really have a known problem. I'm just not %100 sure I'm on the right track and wanted to know other people's thought. It hasn't been running very long, but we are just...

Hello, I've been searching the forms for the last few days, tho I have found a lot of answers, the posts that really had the info I was looking for were older post and I wanted to know if there was...
