    Exhaust gas pressure with a turbo

    I am a rank newbie as regards turbocharging, but would like to "do it right," so, in that vein, I bought a pressure gauge to complement my boost pressure gauge. I plan on trying to run as much as 30 pounds of boost on this motor (it has forged pistons, rods, and crank, and the block is...

    300 hp slant w/turbo... suggestion

    Things to avoid in this build: 1. Ported head 2. Intercooler 3. fuel injection 4. O-rings 5. 4bbls 6. Headers 7. Race gas Well, that is a lot of money saved if none of that stuff is necessary for a viable 300 hp, turbo slant six powerplant, but if you don't HAVE any of those...

    Good guy alert...

    My car WAS a partnership car, with Freddie Nielsen, when one day about 4 months ago, he makes me an offer I can't refuse, to have it ALL MINE, so I take him up on it. So generous was his offer, he basically GAVE me the car, after his having performed countless hours of A-1 quality work on it...

    Slant Six Turbo cost analysis

    I want to do an accurate-as-can-be cost analysis as to how much capital is necessary to spend on creating a turbocharged slant six engine in two states of tune; a 300 horsepower, and a 500 horsepower version. They will both be carbureted, and both utilize as many stock, original components as...

    Which wire for an O-ring

    Our slant six/turbo blew a head gasket last week, showing 50# compression on #1 cylinder and 60# on number 2/ Those numbers have always been 160/160 in the past. We are going to take the hint and install O-rings around the cylinders, but have heard varying opinions about which wire to use...

    Lead Poisoning

    Can someone tell me how to know when an Oxygen sensor is going bad due to lead contamination from leaded fuel? I have an F.A.S.T. O2 sensor and it sticks on one number under any circumstances... It should be changing, but it won't. I bought another sensor for it, but would like to know what...

    New rockers...

    some home-brewed 1.6:1 rockers for our slant six... We learned that they were originally case-hardened (had the Rockwell hardness checked,) so it was deemed necessary to anneal them for machining and welding. Now that they have been T.I.G.-welded, We will have to get them hardened again before...

    Steve Nitti;s supercharged /6 Duster

    The (new at this time; 11/5/'11,) January 2012 issue of Car Craft has a nice article on Steve Nitti's unusually-well prepared /6 Duster, which has a Procharger centrifugal blower on it. The article begins on page 60. Lots of good pictures and text. Worth the price of the magazine. NEAT...

    E 85 questions

    We now have access to E85 "gasohol" from a commercial pump. Our new turbo /6 might benefit from the high octane, we're thinking, but we have a couple of questions about this different fuel. Does anyone have advice about where we could send our Holley 4bbl for modification to run E85 in a...

    Progress report...

    Here are some "mockup" pictures that Freddie took of the engine sitting on the motor mounts. There were some who were concerned that the turbo was too far forward and that it might run into the radiator support/bulkhead. This picture shows the real physical relationship, and that there's not a...

    22" radiator or larger?

    Our /6 turbo project is a race-ONLY unit that will likely never see the street. The car had a 170 in it with a little 22" radiator. Our thought is to simply replace that 46-year-old unit with an aluminum 22"er. Would we be wise to go for a 26" unit? How would we fit it into the...

    Slant 6 turbocharging- yea or nay?

    I have never had a turbocharged car before now. The downside of that is that although I have read a fair amount about it, I still don't know squat. Here are some things I think I know, but am not sure are true. Please correct me if I am wrong. Before I start, let me say this: I blindly...
