Getting 450 Hp

[bruiser937]

Hi Joe, how are you doing? My name is Ray.You come very highly recommended by Steve from Wildponies and the Guys at NY Mustangs.What can you do to my engine to get around 450 HP.(RWHP) I don't want a Super Charger right now.I have a 2008 Mustang GT convertible 4.6 3v. What I was thinking of doing is changing the (using forged) crank, pistons,cam,bigger injectors,headers and x-pipe.Maybe some head work.Changing the rear gears to 3.73 from 3.55.What do you think, can you do this and a around price.The other idea I had was buying a crate motor? Just to let you know I'm and old timer so I would like to hear those cams.(plus my Dad is looking to get a camaro and he is already busting my balls about the HP)Thanks Joe
P.S. If you want to call me 631-7725660 or email me newjack@optonline.net

As old man Floyd says...Believe in Magic...LOL

Supercharger-- $5000 10 hrs of work
All the mods you just listed-- $11000 50+ hrs of work

Now tell me why you don't want a super charger.

 

[bruiser937]

I heard that you can blow your motor up due to not having forge crank and pistons.

Actually I was thinking of getting a short block and heads from www.livernoismotorsports.com/view.phtml?f_cat=Performance+Packages:+Ford:+3-Valve:+Shortblocks

our blocks will hold 450 at the wheels pretty safely. if your going above 500 then you want to start looking into billet. plus, if youre gonna do heads, cam, intake and all that it all has to be done at the same time to match each other component. you can put a s/c onto a stock motor and build it to suit any mods you make thereafter

 

[BoostedStg02]

plus that is only a shortblock add heads-- $1000 for a good p&p intake-- $900 if you get a cheaper one cams-- $700 and then there are so many misc gaskets and parts that just keep adding up (which I am finding out right now). If you have the proper gauges to monitor your car (A/F, fuel pressure) you should be fine as long as you look from time to time for potential problems. I guess all I'm saying is a supercharger is the best bang for the buck plus your gas mileage stays the same and the drivability doesn't change. Just my

lol gas mi stays that same????ya ok!!!not with your foot in it all the time

very true, but you have very few mods and your foot is to the floor all the time.

sry Im on matts comp and didnt realize who was signed in but its Suit

the weak link in the 3V motors is the rods. the block is strong
a blower @ 8 lbs making 425 is fairlysafe. 450 NA has not been done on a 281 3V to date, 400 has and to get there its very costly. built motor 5K, heads 4K, cams, intake... your looking IMO at 2x the cost of the blower and install.

there are a lot of blown 3Vs running around 425-475 whp on the stock short block....
I happen to be one of them....

Sorry I 'm a little confused with your post Should I just get a short block ? I'm not looking to do it as cheap as possible just want to do it right. Thanks for all the input guys I really appropriate it. If this was a small block chevy believe me I would know what to do.

 

[BoostedStg02]

I think what he is saying is you can just use the stock block and get 450hp out of it with a blower or build it up for 3 times the price and have less power.

 

[bruiser937]

So the bottom line is this: get a super charger to get 450 rwhp and everything will be fine.Next question which one, should I get a Roush SC ? Once again thanks for all the help.

yes thanks for the translation

probably safe, there is no clear cut line, I've read of guys losing the motor in the 400whp range and others beating the balls off the car w/ 500whp. a lot of it is in the tune, but it is a gamble. IMHO, get a blower
KB/WHIPPLE/VORTECH/PAXTON or if your willing to spend a set of twins and go around 450whp and enjoy. Just be prepared to spend for a new short block in the future

Kenne Bell or Whipple.

 

[magic maker]

450 hp is a tough number from 281 cu in. To make that kind of power natural would result in an undriveable peaky race motor. We have customers that are running 450-500 @ the wheel with Superchargers for years on stock internals. The secret is in the tune.

 

[MikeyBlacks]

Put a blower on the car or a turbo...450rwhp is very do able & SAFE from both....TUNING def is a big part of the mix.....
Our blocks will hold 450-475rwhp safely as long as u have everything in order.

 

[bruiser937]

Hi Joe thanks for the info. What's the best time to stop by the shop on Tuesday and talk to you about putting a KB kit on my 2008 mustang GT. I will be having surgery in the next few weeks so I was hoping to drop the car off so you can put the SC on. I will be out of commission for about 2 to 3 weeks is that enough time? Do you keep these in stock? Thanks talk to you soon,Ray

 

[BoostedStg02]

Its up to you. Basically there are 4 good brands in my opinion. KB, Whipple, Procharger, Vortec. I have a Procharger and I love it but I'm sure they are all good options. I think the Roots style (KB and whipple) are a little more expensive, they also make a loud winning noise which I like but some people dont so I would go on youtube and listen to some different types and just do a little reasearch. The procharger kits come with everything you need including fuel injectors and i think you have to buy them in the others(42# would be good enough for 450hp). Basically I would research and check out pics and vids and find out which you like the best but I would stay within these four brands.

P
Our blocks will hold 450-500rwhp safely as long as u have everything in order.

Fixed that for you
There is too much B.S. out there regarding guys with ~500rwhp. There has only been ONE motor that has thrown a rod and that was because he took it to the track and beat on it.
