Well, the power supply and the motherboard were "fried" (power surge) so a new computer was ordered,,,, should be here Mon. or Tue. We'll see...

NT Congratulations on your (smart) decision to run this with a turbo, and congratulations on a BEAUTIFUL design! You know how to make me drool.... LOL! I WANT ONE!!!! :)

My computer died a couple of days ago and I am writing this on a borrowed notebook and I hate it... I'll get back to you when I get MY computer back from the shop...

John; no chest-beating and, certainly no offense... Before I go completely silent on this subject (I have hijacked this thread, shamelessly, and that needs to stop,) I did not understand a couple of the things you said and if you will humor me this one time, I promise not to distract you from...

John, I assume your answer to my question of, "How many turbocharged slant sixes have you worked on? How much information, in your experience, do you have about, what these forced-induction engines "like?" " is none, and none. Well, that is completely understandable, as the...

John's First Comment "I am not one to follow the crowd. While my buddies were building v8’s (350’s, 360’s & 351’s), I built my race slant six which was good for an easy 13.9 second quarter mile. At some point I will build a stroker slant six. When I do that build, I don’t see the point of going...

John, I know it's too late in this build to change anything; you are already well-past the point of no return and I understand that. Be that as it may, I was just curious as to why you chose the AMC engine to power this Barracuda when it entails so much adaptation and fabrication, not that...

My time od 91.5 in the eighth mile equates to about 112 mph in the quarter and was run on only 15 pounds of boost. The quarter-mile elapsed time for that run would have been about 12 seconds, flat, according to the Wallace calculator. I think those are OK times for a 225 slant six, running...

Get the right-sized turbo and the "lag" or, lack of low-end torque is no longer a problem. It's all about sizing.

But, research has proven that slant sixes with turbochargers run the best quarter-mile times with final drive gear ratios in the 2.76 range, so, there would be no need for an overdrive if you just geared the rear end like that. That "one size fits all" gearing would work for all kinds of...

That bolt appears to be in the piston, but, it's not... I machined a cylinder-size (less .010") piece if eighth-inch-thick aluminum to catch the shavings when I cut the O-Rings, so that when I was done cutting, I could just pull the aluminum piece out the top of the bore, and, the shavings...

I agree than a rear-mount turbo is the only choice that makes any sense in this particular application. It will free-up a lot of room under the hood, and run a WHOLE lot better than it does, now!

What he said!!!

Yes, that is the perfect carburetor for this buildup. Perfect! Use the modifications described in "Hangar 18" website and monitor the A/F ratio with you new O-2 meter and you'll be fine. Holley sells a 2-box set of jets (all sizes) to enable that. Get a set... The O-Rings are for...
