1000 hp crate engine swap, anyone? (Page 1/2)

GM just revealed a 632 cu in 1000hp crate engine. Anyone willing to put it in their fiero? would make quite the splash in the sea of 3800 and N* swaps lol, thing probably weighs as much as the rest of the car

It would probably frag any transaxle that was bolted to it, in very short order. And it would still require an adapter plate.
That's assuming you could find a big enough shoehorn to actually fit it in.

If one chose to attempt a swap with that engine, the cost of the swap would end up being many times the value of the car. Must agree with Raydar in that you couldn't find a transverse trans that would fit that can take this type of horsepower.

Bolt pattern and price tag? I don't think the TH125C is going to hold up to that kind of torque.

It is based on the 572, so the bolt pattern will be BBC/SBC.

The 572 is a $16K crate engine, so this one is likely a $20K to $25K engine.

Back in 2007ish, there was a company building a $15K transaxle that likely would have worked with this engine. Doesn't look like they are still in business...

Crikey, 1000 HP from a motor with one camshaft, two valves per chamber, and a 'throttle body' (not sure what it is called) and air cleaner that are no bigger than the carb and air box on any SBC from the Good Old Days, all without any boost or special headers (I assume). I guess port injection is way more effective than I thought ...

Do you think they will make a 60 degree V6 version?

wasn't any v6 crates in development as of a few months ago, but I wish

Back 2 decades ago I read an article in either Hot Rod or Car Craft where a professionally built Chevy Big block produced 1050 HP- at 6500 RPM. It used Pro-stock Aluminum heads and a SINGLE 4-Barrel Carb.....Was actually making over 1000 HP at 6000 RPM...

A few years later I noticed something; I don't like comparing engines by "HP per STATIC displacement".....Instead I do "RPM X Displacement divided by HP" to see how much actual air the engine has to process to create the HP- basically to see how efficient the engine really is.

SO I took that engine which is 9.2 Liters X 6000 RPM = 55200 divided by 1000 = 55.2 liters per minute to create that HP (Most stock engines are between 70-95 L/M)

Then I looked up the Formula 1 engines and did the same calculation; 2.65 L X 17,000 RPM = 45050 divided by 750 HP = 60 Liters per minute.

That means the big block Chevy PUSH ROD engine is more efficient at producing HP than the super-duper high-tech Formula one engines!

(Yes- I know that the engines are not processing quite the amount of the displacement- The airflow limitations would cut that number down- but the F1 4V engine would seem to me to be better at air flow....making it's "Air processed" number even worse vs the 2V Chevy)

Too many armatures think it is the top HP number that matters.

What matters is how much HP one puts to the ground.

A friend of mine was a local racer. He did not have the biggest engine, he did not have the biggest tires. He did not have the most HP in his car but he never lost.

Why? He has the car set up with good power, soft tires and a suspension that put all the power to the ground. It has the right springs and a slightly altered wheel base.

He could hammer the car and get very little if any wheel spin. For every rotation of a spinning tire on his competitors car he was moving forward one tire roll out.

So many people think too much cam. Too much carb, too much compression, too much gear. They spend a lot snd get too little results because they have too little chassis.

It won't do the quarter mile faster or handle better than a worked L67 with third of the power.
