Re: Inline 250 - T3 Turbo - w/ Video
Nice picture!
One question, how do you control ignition? Do you retard timing under boost? Sorry if this information is in the thread somewhere. I looked through all the pages and didn't see anything. Your pictures are gone from the inliners forum also so I couldn't see what you did there, either. Thanks, Chad Edit: Okay, I just read through a little more slowly. Your running HEI with mechanical advance... did you ever hook up the vacuum advance? If so, did you lock out the advance at a certain point? Thanks again, Chad

With my setup, I have it running on the rich side and have never had any detonation yet. I have the wastegate set at 10 psi. If I were to run more boost, I would most likely get a BTM box to remove timing, but where I am running it, there is no need. For my setup, it is right at its sweet spot. I hope this makes sense.

Re: Inline 250 - T3 Turbo - w/ Video
"BLOW ME OFF!!"
well sort of, that was the engine talking. After much contemplation on whether to pony up and purchase a genuine Tial, Turbosmart, Greddy, Forge blow off valve, I decided to take the value route and hope for the best. I decided on a pull-type blow off valve from ebay. Sold by ebay seller "Wyntonm". It is a 44mm BOV that comes with a band clamp and nice polished stainless tube. It was delivered to my door (Nashville,TN from Washington) in about 3 days and set me back $65. All of the pieces seemed very well constructed of billet aluminum. The first thing I did was take it apart to inspect the diaphragm and valve movement. The diaphragm was a piece of silicone rubber that allowed the valve to "blow-off" about 3/4" of movement. The complete construction of the piece was very solid, the first thing that I noticed was its density. It felt like I was picking up a cannon ball. I took a few vacuum measurements of my truck at idle, part-throttle and throttle rebound. They were 15 in hg, 8 in hg, and 20-25 in hg. I first hooked the BOV up with no adjustments. At idle it had a slight clatter of the valve. This was caused by the BOV opening at exactly 14-16 in hg. So I needed to increase the spring pressure on the valve. I put one washer under the spring and it increased it just enough to keep the valve closed at idle. After a few WOT runs, the BOV seems to be working flawlessly. The sound emitted is barely noticeable and sound like a large blast of air. Very powerful, instant and no shudder. The only issue that I see, is that the BOV is not easily adjustable. If someone needed a wide range of adjustment, you might want to look for another one. Video Clip: http://youtu.be/Ou7F8NOLxqs Boucher'

Re: Inline 250 - T3 Turbo - w/ Video
Hey boucher any pics of how you mated your T3 flange to your up pipe running from your exhuast. Custom piece or off the shelf stuff welded together?

At first I ran a gasket between the flange and turbo, but always blew them out. So, then I filed both flanges smooth and just put high temp copper gasket maker on it and bolted it tight. I haven't had any issues since.

Re: Inline 250 - T3 Turbo - w/ Video
What happened to the videos? Wanted to watch them again and it says the video is private. When I go to YouTube, it says the videos have been deleted. I need some motivation here!

Re: Inline 250 - T3 Turbo - w/ Video
Jeeeez! Alright I think I have it figured out. When I decline the google + offer, it resets all of my links and locks them out. I just went through all the videos and made them public.
Please try them and let me know if they are operational. Thanks, Boucher'

Re: Inline 250 - T3 Turbo - w/ Video
This is a great project! I think every engine should have a turbo hanging off it! You did a nice job making it all look nice too, almost looks factory.

Re: Inline 250 - T3 Turbo - w/ Video
After a successful "Gas Monkey" project, aka Cropwell. I have turned more attention to JED.
I really liked the look of the Offenhauser carb hat, but in function, it lacked. The hat was designed for a 4.5" carb opening. I had to run a plastic adapter for it work on the Holley 5 1/8" spread. Plus, the air flow from the turbo was choppy at best. So, I went for a Extreme Velocity hat. These are supposed to be the best. The construction was awesome and from its looks, the flow couldn't be designed any better. Here it is on, but not painted the cast iron yet. For it's performance... whoa, read below. Also, I was dealing with a real lag in building boost. I had modified the internal wastegate to open around 4-5psi. What happened it started to open at 2 psi and fully open at 5psi. So boost took forever to build and was a dog. So I ordered a Voodoo V, manual boost controller with a lightweight ceramic ball. I installed it and tuned it for a 10psi boost setting. Good GOD, what a difference! Boost comes in much sooner and pegs right at 10psi and holds there. It actually raises the front end of the truck when the boost hits. While this was totally awesome, my AFR's are right at 12.2 when WOT at 10psi, a little high for my comfort level. I think a jet bump up will fix that. Believe me, the difference between 4 and 10 psi is Night and Day. Still shaking my head. I have this sneaky suspicion, that this setup is right at the point of breaking other stuff... trans, rear end... For winter, either a built up TH350 or 700R auto tranny with a 2500-2800 rpm stall converter. I cannot wait to launch a turbo'd inliner at 10psi with a dialed in auto trans!! psi-psi-psi's Boucher'

Re: Inline 250 - T3 Turbo - w/ Video
Nice work! Sounds like a great improvement. You may want to try setting the WG to 7-8psi for even better spool up. Once you get around double the WG setting you could run into the flapper blowing open too early even with the MBC holding back the signal.
Have you measured your IATs?

Re: Inline 250 - T3 Turbo - w/ Video
One great thread I must say for starters! Thanks for the info, not sure if I am gonna throw a turbo on my 6; but I'm contemplating and seeing this just makes me want to do it more! Nice job on the motor! Really looking good! On 8 pounds of boost a stock 250 makes around 304 hp. So I would say with the extra mods you have done yer making around 380 hp! Bet it pulls perrty good though! It is definately a V8 threat! thanks for sharing and to add to the stress....The videos won't work for me either!
