400 horsepower
 

ok im tryin to get 400 hp all motor no power adders, i have a 98 gt auto wit cai, 4.10, flowmaster exhaust, diablo tune, with stock heads and cams, i no i should a pi swap im going to be doin that soon, but what else should i do to get up to 400 hp?

is it even possible to get a 4.6 2v into 400hp without s/c, turbo, or nitrous??

oh its possible and im guna do it i jus need help with what to do lol

lol no i really dont think its possible...

i mean you can get ported heads, ported intakes, new cams, long tubes, o/r midpipe, catback...etc i just dont think you can hit the 400hp mark

highest power with stock long block ever is 325rwhp. thats the most i have ever seen. You will not crack 400rwhp with a stock short block, i dont think you will with a 2v even with a higher compression big bore motor, do yourself a favor and get some kind of power adder.

yeah, 320 to 340 RWH will be the most you can get. Even with my 5.4 the max i will be able to do is those same numbers. I do plan on a power adder so i can get over 400 RWH, but the TQ will me mad crazy with the 5.4.
Even if you stroked it, you get some HP but usually it's tons of TQ.

yup, the most i saw was like ~330rwhp and that guy had some serious $ in his engine, if you get 400rwhp out of N/A 4.6 ill buy you dinner!!!

i will buy him 2 dinners!

Hell, if you hit 400 Non added on a stock 2v shortblock, ill buy you a Venom Nitrous 1000 kit.

im dead serious too. Lol.

400 is as high as you would want to go without a built engine. yer not gonna see that non added.

Its possible with a motor. Just not the one you have.

If you've got the cash...there you are!

What's that now...three dinners and a Venom 1000 setup, PM me for where to ship it! :poke: LOL!

thats flywheel hp
heres a link where a guy got 361rwhp on a 2v'

that motor does not make 400hp sorry. Plenty of guys have more radical 2v's then that and they are still lower 300rang. 281ci arent gonna do it.

Honestly, I don't think my 4 valve could make 400rwhp on all motor

Wait, so if this guy had bored at 0.60 over or even higher instead of just going 0.20 over, you don't think that could make up that 40 hp? I'm not saying it is a good idea, but I refuse to believe it can't be done.

Plus he's running a catted setup which is costing him about 10hp to the wheels. I think 400 is entirely possible if you have the money to throw at it.

my friend stroked his saleen 4.6 to a 5.1.. had 330rwhp, with cams, stock heads, full exhaust.

Even with a set of RACE ported heads you just can't flow 400rwhp worth of air through any modular 2v. read that again so you really understand. YOU CAN'T FLOW ENOUGH AIR THROUGH A 2V TO SUPPORT 400rwhp NA. IT IS NOT POSSIBLE. not even with the most radically ported heads there are limits.

3v and 4v technically have the flow capabilities to do it at very very high rpm but those are not street friendly. FRPP managed to make a crate motor that's a 4v which does it but that's a RACE motor.

Get a realistic goal and we'll help you figure out how to get there.

Remember, hp is a measure of air pushed out the tail pipe for all intents and purposes, the 4.6L cylinder just isn't really big enough to do that at reasonable RPM or compression ratios and definitely not on a 2v head. If you want to spin 9k rpm and have no tq and no chance of passing a gas station unharmed, then we can get you close but not all the way there.

at 9.6:1 compression the most that motor will ever see is about 320rwhp. Which is about 375bhp. That's with a wild set of cams and a very street unfriendly setup.

With all the money you would be investing in your motor you might as well just buy yourself an 01 cobra and get 320 HP stock and just go from there. Your wasting your time elsewise.

Mike Horne of texas hot rods with his built High compression 2v is only putting out 307rwhp; given he's making almost 500 on spray. There is no way of getting 400rwhp outa a 2v all motor.

I'll be the oddball of the group. I think it can be done. You gotta make it rev like 8K and get the right cams, hogged out heads and a really high compression ratio. But it can be done.

Do you realize that you'll have to make at least 475bhp to even come close to seeing 400rwhp? Any idea how much air that is?

Abandon thread... abandon thread. Unrealistic goals being bandied about.

Just get the bastard as fast as you can. Whether you hit 400 or not, who cares. It's how you use the power you have.

w00t. Max effort engines are a high maintenance PITA and don't work on the street pretty much at all.

You can make it happen if it's built right. I'm actually going all out on my 2V NA. Huge Cams,Forged and Stroked internals (B & B)and Ported heads with SLP LongTubes and a slew of BOLT ON's. Nothing like the Bada$$ sound of Big NA Cams. I look at SC's,Nitrous and Turbos as STEROIDS.Sure you'll put up big #'s but how long are you gonna last.Remember the 2V isn't built for all those POWER ADDERS. keep it ALL NATURAL!:punk:

arrrgghhh.. bullsh!t alert bullsh!t alert. Too much ignorance... I'm bowing out.

you will need to rev that thing well beyond 7000 rpm to see 400 hp and the stock rods and pistons definitely won't last long doing that.

you will need a beefed up short block. some wild cams, and ported heads along with a lot of compression. It won't be much fun to drive on the street like that either, it probably won't idle well and you will need some very short gears to get into your powerband




modular motors LOVE boost, they suck it down like candy. It's almost as if these motors were designed for forced induction.



Don't come crying to us when you hate your car cuz it's a pain in the ass to drive.

you beef up whatever you want 400hp isnt gonna happen. Why spend more money when you can get a blower,turbo, nitrous setup for so much less and make tons more power.

I dunno about 400 hp, but you can take a 2v 4.6 and put it in the 10's running N/A. It's been done by a guy on modulardepot.com
