Running 20lbs of boost, how much power to do look to make? I just saw the two bolt mains...how do you think they will hold up?

I'm hoping that they will hold up well, lol. They are high-quality ductile iron held on by Moroso 1/2" bolts. But, I'm going to talk to KRP again and maybe try to find some 4 bolt splayed caps.

I designed a set in CAD, lol:

Does that count?

I hope for 450-475 HP at 20 lbs of boost and 8000 RPM. If it gets there, yay! If I only make it to 400hp, I won't cry.

I don't think you are going to get 400HP with 20lbs of boost - more like 320 would be realistic and the 2 bolt mains should hold up fine at that level

Hi Nate,

Here its something to think about if you want to use a 2 bolt mains block with lots of boost and to produce the kind of HP you are talking about, this is a picture of a 2 bolt mains block V8 engine to show you what can be done to achieve what you want:



this picture was borrowed from the Badd-A$$ racing engines company, and this is the text that follows this picture:

2 bolt main blocks can be used for racing engines when one of our main supports are installed. You can see how it ties all of the main caps together and turns an ordinary 2 bolt main lower-end into something many times stronger than a standard 4 bolt main. These are a must for small block Fords and 2 bolt main Chevy's when using high compression, blowers and/or nitrous oxide. Our billet main supports are only available ON our engines. We do not sell them outright.


P.S. I hope this info can be helpful for you to get an idea of what can be done to make it stronger than already is right now.


Good Luck with your project ...
Ales

Why do you think this is not realistic?

20lbs. of boost on a 2.3 liter ford is goood for about 220 hp on a stock engine, on a fully prepped engine maybe 300 to 320 hp

Finally the build thread, with my favorite engine! Keep it up! If you find a cheap source of SD4 parts, let me know For now I'd be happy with the SD head and holley intake and TBI on my stock duke; until I can afford to get the block, crank, and other parts.

You are an absolute idiot.
You do realize those turbo engines from the factory were rated at 190 hp from the factory(pending on model) with max boost being around 11 psi set from the factory. A boost controller, a intake DP and exh on those ford 2.3 motors would put them well over 300 hp with 20 psi. However the small t3 that is on there doesnt' do too well at 20 psi. Might as well swap to a larger turbo by that time.

I think Indiyfieros biggest prob is getting it tuned right with a carb setup. But tehn again I think he is running some sort of EFI setup. And the carb is just to let air by through with the injectors in the intake mani. I might be wrong though.

hey Mr Punisher - who you calling an idiot? you know me about as well as you know ford 2.3 turbo motors - do you know who Joe Morgan is? Here is a Link to his 400HP 2.3 turbo http://www.turboford.org/faq/joe.shtml if you can read you will notice he is running 17 psi of boost with a 90 HP shot of nitrous to achieve that 400 HP. And at this link http://www.merkurencyclopedia.com/Dyno_results/dyno_shootout14.html ther are several dyno sheets from 2.3 turbos running 20+ psi of boost and none of them making 400 HP. As far as ford 2.3 turbo motors having only 11psi of boost I suggest you read up on them a little more. My totally stock 88 turbo coupe motor would hit 14-15 psi of boost and it was making about 200 flywheel horsepower. Turning up the boost to 18 psi took about 2 tenths off my quarter mile time. I don't think turning it up to 20 would have gotten me 400 hp.

Like I said some had 190 hp crank from the factory. Turning up the boost 5 psi will yeild more then 30 hp. I also stated intake DP and exh as mods as well. 20 psi is too much boost on that tiny T3 which is why I said its better to just go bigger at that point

And I never stated anywhere anything about 400 hp. Which tells me you can't read. Which furthers my argument about you being an idiot. See those of us that aren't idiots can read and you prove nicely that you can't.

Thread hijack. Thats it for me here. Back on topic.
