Official Scraping of the Offenhauser 3-1V...new direction...

[CobraSix]

Okay, I've dropped some hints...a few people have asked questions.

I have scrapped the Offenhauser project in favor of the Aussie 2V. I did this for many reasons, but the main one is long range drivability. I drive almost 50miles one way to work...and the Offy is just a little too hard on my legs for that (I think my right calf is so much bigger now). I want something a little easier.

I'm also changing because I want something with a little more ability for future power adders (read: Forced Air). I've already got most of the plans in the works...but it is likely to be next summer before anything happens. I need to do handling stuff this winter along with interior work (request of wife). So...hopefully...sometime soon I'll get the parts from Mike and I'll be off to the races so to speak.

The offy looked soo cool and boy did I get a big response from it...definitely the way to go for a crowd pleaser or local driving.

I'll give everyone a seat of the pant comparison of the two when it is all said and done.

dare I ask how much you are looking for

Funny you should ask...

I'm not sure if I'm getting rid of it just yet. I may try to make a vacuum activated set up for the outer carbs vice the mechanical linkages. That would be a very nice set up. It should actually be fairly in-expensive to do, should cost less then $150 to make it, depending on a few parts.

If I don't do that, I will definitely be selling it. Even if I do make that set up, I'll probably sell it as a Demo and maybe market the entire set up or at least show people how to make it themselves.

Sorry to see you leave the Offy family Slade. That air cleaner was cool.....

I am interested in hearing what you do next....

Bill,

The other thing is that I would like to get about 150-200 RWHP...and the Aussie gives me more possibilities to get there.

The Offy was cool though...and the comments great.

Slade,

What kind of real wheel numbers do you think you were putting out with the offy?

I am really happy with mine, but like you said, I don't have to drive mine all the time.

Here I go... Just to rain on the parade...

The kind of RWHP you want will be tough for a daily with a 200. When you add the cost of ignition controllers and the forced air and the 2V head/rebuild, you may run close enough to the price for a carb crossflow.

I'd suggest you do a price comparison of the two before committing.

Regards, Adam.

It would be difficult. But not impossible...if you went the 200 crossflow mod like Jack has in Locost.

 

[CobraSix]

Well, if a stock Aussie head gets 110 RWHP on a stock engine (from mustang geezers tests)...with a hotter cam and ignition that I have, I would bet I could get around 120 RWHP. I'm looking and forced air to help get up to 150-200RWHP. A super shouldn't make it too undrivable. If it does...it goes bye bye. Once again, I'm looking for something different. I'm a big fan of Forced Air engines. I've got one right now, about to acquire another one...so might as well make all my cars forced air.

If I'm way off base...let me know. From what I've seen, I mild supercharger should easily give me about 30-40 HP, which will increase my RWHP by about 25-33 RWHP at least.

8) Go to http://www.40bob.com/index.html and email him and ask him if he would be willing to weld up a tubular turbo header for a 200 I6?

He came on here before trying to determine if there was enough interest in them to make and stock one. IIRC he was willing to make one but I dont remember if he needed a car or just a exhaust manifold to work off of.

If its not going to be for a month or so I would be interested in one.

If you want to go cheap you can use the pre emmisions manifold and go to www.turbocity.com and they can put together a parts"kit" , they cant sell you a complete assembly because then they would need emmisions certification but they would be happy to sell you whatever parts you wanted. Think of it as a kit broken into a "componenets" set.

A turbo header on a 2.3L turbo motor can pick up more than a few ponies so it should do wonders to our motor.

I"m thinking Supercharger just for ease of design and setting up of the system. While I love turbos, I don't want to have to make a system for it. They are more intricate then superchargers.

On a supercharger you are going to have to make your own brackets, line up the belt, and adapt a drive belt, and depending on the supercharger run your own oil feed lines and oil return lines.

On a turbo you go get a internally gated T3, buy a J-pipe from Turbo City with a T3 flange on it, run an oil fed line and a oil return line. Make a stabilizing bracket or strap that can bolt to the turbo and the block so the turbo doesnt move around and all thats left is plumbing. You can get a good T3 for around $100-$150. If I could get a turbo header it would be nothing to do a turbo install in an afternoon.

I think a supercharger install would easily take twice as long. And a turbo would be more effecient.

Any good links out there for setting up such a DIY turbo rig? And what compression ratio and boost numbers are sane for pump gas? Thinking of the possibilities of a turbo mated to an OZ head. Cogito, ergo vroom!

Oh, Anlushac11, I've been meaning to ask. Is that a B5 reference, or a coincidence?

100% Intentional. Im a B5 fanatic.

The '79-'81 Carb turbo Mustangs ran a 9.0:1CR with no intercooler

The '83-'88 EFI turbo cars ran a 8.5:1 CR and IIRC ran 12lbs boost non intercooled and ran 16 lbs boost intercooled. With a better intercooler and 8.0:1 CR and wiht 95 octane or better gas guys are running 18-25 lbs boost in the 2.3L's and making over 300rwhp with a hipo build up.

www.turbocity.com can sel you any parts you want or need. Only thing they cant do is sell you a complete kit since they would need EPA certification. They have to break it down into component kits. They sell all the turbos, turbo rebuild kits, bearings, seals, carb bonnets, a Buick GN 2bbl carb box to sit on the inlet side of the turbo if you want to make a draw through setup. I personally want a Throttle body injection unit because I would get all the driveability of EFI with the ease of a carb setup.

all the efi 2.3L's had 8:1 pistons. the key thing is that they all had forged pistons while the carbed turbo cars had cast.
