from scratch fox project, modern or 5.0 based?

You can buy stock shit that will hold 1k these days, we are talking about making 1k with the proper suporting cast. Put your 1k hp bottom in something and lean it out real hard a few times and I bet it won't hold 100hp

No stock mustang bottom end will take 1000
Hp stock... If you want it to last any amount of time. The 5.0 and it's boss have powder forged rods, and lightweight pistons. Those will NOT hold 1000 hp, they are made for fast revving n/a applications.

The termi lower end really isn't that great either. The zohlner pistons are very light duty compared to some drag racing f/i slugs. Many many termis have been roasted at less than 1000 hp.

Speaking of which, "leaning" out the cylinders isn't what directly kills them. The high combustion temps of stochi afr is what does. 4 cycle turbo charged engines in airplanes are tuned to cruise at 15-17 afr with many lbs of boost, but because it is far from stochi ratio, the combustion temps are lower, so nothing gets roasted.

lol.... leaning out... which means changing a/f ratio.... thats what he is saying

I have high dollar parts ready for assembly...only got 2300 in it. Just gotta search craigslist and pounce...that is including all the machine work. I know for a fact it will hold 1000rwhp

Fact based on what? You gotta be kidding....you'd need to spend that on the lower internals alone.....and then it would only last a short while.

Billet Manley rods with 5/16 arp 2000 bolts
Fully machined teksid bored .020 over
Crank balanced and polished
diamond flattops with tool steel pins, moly rings
Arp studs on the mains

Just need some bearings and imma build that sob!

People will dump race parts at retarded prices when the bills need to be paid, especially when it's piece-meal.

What kind of Crank? Internally balanced? Everyone runs ARP. Whats the block? I'm not impressed yet. Or convinced.

Ok wtf. This is a modular. Of course its internally balanced! Am I going to put a weezer balancer on there? L0L

Teksid= early aluminum cobra/mark viii block. This particular block came from a cobra, along with the stock 8 bolt crank

Ok...settle down. You build your 1000 hp motor...and get back to us on how long it lasts. Obviously you know something that no one else on here knows. $2,300 budget compared to $20,000.

Besides....with the budget this guy has...he isn't gonna look at Craigs list for race parts.

I agree, but he did say he wanted to do some of it himself.

Sorry, I do understand that not everybody knows modulars. But just FYI, if you are going to mess with them, go to arlington machine because they are one of the very few machine shops in the metromess that can correctly machine modulars. (torque plates) and, they do all of gearhead's machine work

I didnt say stock mustang internals and I damn sure wasn't talking about the new 5.0. Just an example ford gt have put 900+ to the wheels with stock shit. The terminator lower is not the best but light years ahead of what was in these cars 15-20 yrs ago. Also I never said leaning a cylinder was the direct cause of any engine blowing up but it is a root cause. You ever seen a piston after a cylinder leaned out and detonation insued they try to escape from the cylinder.

Planes run a different fuel most times all together and all fuels have a different stoich zone. E85 is stoich at some where near 9:1. Plus you have cooler intake temps and a lot of other factors in a plane that don't equate to race car shit. When a turbo motor is going down the track and the intake temps are 150+ and you lean it out to 15-17:1 afr some shit is gonna glow. There is no denying that let's keep apples to apples and leave the lemons out of this. The more fuel you put in a cylinder the colder it will be. Fuel is a coolant. Cars run stoich because they put out less hc, co, co2 that way and you bring in egr to lower cylinder temps to reduce nox gasses. Stoich is an emissions thing and that don't apply here

Actually, airplanes do run lean when cruising. Its called "Lean of Peak" basically, the pilot keeps taking fuel out while watching the cylinder head temps. They peak at stochi, and drop off afterwards because there is too much air in the mixture. In this case, air is the coolant. This allows safe operation and max fuel savings.

This is not implemented in cars because of high NOx pollutants and it will burn the cats out. However, it is completely safe, and was used back before there was such stringent emissions.

Plane at several hundred MPH, car at ~70 MPH. Notice a difference in the ability of the air to cool an engine? Let's not forget that the air is cooler at altitude.

I'd go so far as 50, but 40-50 is likely. I plan (and want) to get my hands dirty along the way so that should help, my biggest enemy is time right now.

Get your hands dirty by writing me a check and kick that '93 to the curb
