So now 300 or less and you are wrong?? 300 and 400 is a BIG difference. And its DYNO, with a "Y". (You know I'm just giving you chit.)

Sorry just got off of work. In between 300 and 400 is kinda where I think it will be. 332-340 hp and I will be almost correct on the 400. we won't add in the transfer case or the front/rear diffs. We shall see what it really does.

Also I edited it for you dan.

ASA certs simply mean you can turn a wrench and follow directions, not much else. You said 400hp? On who's estimate? You don't know what was done to the engine, you have no idea who ported the heads (if they were even ported), you don't know the cam profile, you know absolutely NOTHING about it. So how can you estimate the horsepower of that engine? Do you know the flow numbers on the heads?

There are a million questions I can ask you but you don't have a concrete answer for any of them. Most people estimate how much they think an engine will put out by comparing it to other cars with similar mods. Generally guy has "x" engine, and you built an engine using similar heads and cam profiles, with the same bolt-ons as engine "x" then you should have similar numbers. But each engine is different. Some engines have more blow-by and thus lower compression. But you don't know any of that information squirrel. So you can't estimate anything. Show me a time slip w/race weight, or a dyno sheet and then we can play juggle the numbers.

I'm not trying to insult you in the end. I'd rather educate you so you understand a bit more about how an engine makes power so you'll be less likely to spread misinformation.

Since when did I argue anything about power loss through manual or automatic transmissions?? I know there is a difference but I never even brought it up. I just like how you said you are putting down 400 HP and now all of a sudden you are almost correct at 340. Last time I checked 60 horsepower is a big difference. And I know you are going to say that is with drivetrain loss, and you were talking 400 at the crank, whatever. No one dynos their motors at the crank, it is just an inflated number to make people feel they have a faster car. All that matters is what is getting to the ground and I am still going to say no way are you getting 400. I would be shocked. I'm not doubting that it's quick for what it is, but you can only get so much power out of those motors. I would be suprised if you dynoed over 330 seeing that it is AWD.

Car nick names or your nick names????

JK!

NO KIDDING! 400hp on a 4.0 explorer???? They start out with 215 IF its an OHC and not the base OHV model (185hp I think).

NFW 400hp. I'll pay for the dyno run if that thing can put more than 350 to the rear wheels.

No mention of NOS, turbo, or blower, so with all due respect man....you're on crack if you think it can produce ANYWHERE close to 400hp, even at the crank! Think more like 225-240 RWHP if you've done a good job building it and the head has great port work, etc, etc.

BTW....17-20% loss is typical for most auto transmissions.

He said it is AWD so it will be putting even less down due to more drivetrain loss.

Unfortunately those who are new to hotrodding full sized cars (especially the import guys) seriously over estimate the horspower output of their combinations. The other critical factor is torque and the power curve. HP is calculated, not measured! HP is (torque x RPM)/3456. "Torque Motors" like the 4.0L OHC Ford (I own one) makes power down low and can't breath past 5000rpm. So even with serious port work, custom re-grind cam, intake porting, etc. The power will still be modest but the torque curve could be strong & flat which would still make the Explorer feel pretty powerful.

LMFAO! Great...
