Insane NA HP.

http://www.honda-tech.com/zerothread?id=1376406

I was looking around on preludepower.com and came accross this in the 5th gen section. Don't know if anyone has seen it or not but read the artice and look at the dyno graph. Re-freaking-diculous. My favorite parts of the engine are the fact that its a 2.7L, and the awesome enclosed ITB's with CAI, and RMF header.

Check it out and see what ya think. :iceslolan

What the hell? No one wants to see this?

O I saw I just didnt reply...thats very nice over 300whp n/a

I've know about this bad boy for a while.
What really is spooky how many 2.5L ludes are creeping around!

That is awesome N/A power

Well, that engine is defanetly my dream engine for a lude.

How much does a Prelude weigh??

How much does a Prelude weigh??

For 5th gens...

Base- 2954 lbs.
SH- 3042 lbs.

That isn't very good for them. That's somewhere around 1200lb per litre. I just hate the idea of sinking a ton of money into a little engine to get decent HP and TQ.

Yeah, Frank sure knows how to build some awesome motors. That header has alot to do with its power output as well ;)

Pounds per litre doesn't mean a thing...hp per litre tells more about the engines performance.

Power to weight ratio is a better measure for overall performance of the car - The article claims 361-372 HP / 269-277 ft lbs at the Crankshaft. That's 149 hp per litre from a 2.5 litre engine, and a power to weight ratio of 0.126. Impressive numbers if you know what it all means.

Ahh ever since I found out you joined here I knew you would respond in this one, seeing as how I got it from pp.com.

Yeah RMF all the way lol.

Yeah I know what that all means. But someone could probably spend the same amount of money and get around 150 hp per litre from, let's say a 455. That would be around 750hp give or take. Let's also say the weight of the car is 4000lbs ,which is an over-estimation. The power to weight would be better than 0.1875. "Impressive numbers if you know what it all means."

actually, 750hp in a 455 engine, or a 7.5 litre, would be 100 hp per litre, which is not as impressive, numerically anyway, though it would still be a fast car. I think small engines putting out numbers like that is impressive, whether you like imports or not, I would think you could respect the fact that he got those numbers out of a small engine with 4 cylinders.

If you know what it all means can you explain how pounds per litre affect performance?

j/k dude I don't want to get involved in your 4 cyl. vs 8 cyl. flamefest that you seem to be trying to start. It's an old and tired arguement that brings out the worst in all of us...let it rest please.

Yeah RMF all the way lol.

you know it, lol. I'm beginning to really like this forum. But it seems like alot of people are misinformed/uneducated on alot of topics, but you can always learn. :)

Yea sorry about that a 150 hp per liter would be like 1125. Don't get me wrong though I do like four bangers I used to have one. My brother is building a AWD 91 Tsi that im helping with. I really want to see the end result. The goal is to see who is going to win in a race. It's going to be a completely rebuild 69' Cutlass with a 455 and his 2.0 DOHC turbo. We are in the process of buying performance parts. Whenever we get our cars done and race i'll post pics and maybe even a video. If I actually get beat i'll have a newfound respect for those little engines.

Depending on what each of you plans on doing, I wouldn't be suprised if he does beat you. Though I'm not a fan of DSM's, you can get those cars into the 11's for under 5 grand.

I guess you'll just have to wait and see now won't you.

Keep us posted then, i'm interested to see who will win.

Sorry man it will take a while I have 2 projects right now. My brother almost has his done. He has the engine almost completely built he needs to clean up the engine bay and get some electronics. I'm rebuilding a 69' olds 350 that im putting into my 85 cutlass. That'll be done around the same time his will so i'll race him in that first. But the 69' cutlass should be done hopefully by next summer.
