Heres the deal, I have a 5.0 with 300hp at the rear wheels, I want to push 360 or so, I need ideas on what to do. Id rather not get into the internal engine components but opinions are still considered.

Engine Now:
302, with F303 cam, edelbrock aluminum heads, edelbrock performer intake, 24lb injectors, smog delete.

Not sure the rest but any ideas of what I could do? Not a huge budget but still throw me some ideas. Thanks in advance guys. Sincerely, Will.

Well, theres the obvious choice of adding some form of boost.

 

[slayton93]

i was thinking the same thing but everytime i check it out its always $1500 to $3000 for a supercharger

 

[cindys_sn95]

why 60 HP? i do not like N2O, but that would be an easy and inexpensive way to go.

 

[slayton93]

im just aiming for around that area because i want atleast 400 at the crank. its gonna be a street rig and ive heard that n20 is a killer on the motor

 

[cindys_sn95]

not if its done right! and do not get greedy! and to get 60 HP, without going back into the engine you do not have a lot of options.

 

[slayton93]

haha thats true, i've noticed that superchargers are all $3000 but what about a twin turbo?

 

[YLDPONY]

You think superchargers are expensive? Start to price out turbos...

However, a cheaper turbo setup may get you your 60 HP. I still don't see it happening for less than $2k.

To get 360 to the wheels your gonna need a supercharger(cheapest in the long run), turbo or nitrous. And you need more than 60 hp cause that setup isnt 300 to the wheels.

First off how did the dyno graph look like when you pulled 300 to the wheels?

Second to get 60 more horses to the feet will take either going into the motor or some FI.

u do have another option .... Victor jr spyder efi intake 90 mm elbow 90 mm throttle body Have ur heads bowl blended and maybe some chamber work.. good ed curtis cam and turn it 7000 ull get it.. add a set of 1 3/4 kooks headers and electric water pump u should achieve it.

Why TWIN turbo? why not just single turbo? your gonna pay 5,000+ for two turbos that produce 30hp each...Supercharging is much cheaper and less of a headache and works muuuch better for a street application. If you can get a supercharger installed and tuned on the car for 3,000 you have done some good work. Its gonna cost at LEAST 3,000 to do it right. But you can always find a used paxton or vortech and just buy all parts individually (fuel pump, injectors, mass air etc) and just slowly buy all the parts you will have yourself ready to go without having to fork out all the money at one time

 

[slayton93]

the set up is 300 to the wheels, thats not all it has for parts, im not sure everything else but it has forged pistons and etc just cannot remember what i was told when the car was bought 2 years ago, and thanks for all the advice everyone, i appreciate it

 

[spdjnky_42]

If that setup put out 300 to the wheels then the compression has been bumped. I would not use a turbo or supercharger on a high compression motor.

 

[slayton93]

ya most likely, im thinking about just going with more engine work, maybe a new cam and like Pearson88GT mentioned ill probably go with the victor jr intake with 90mm throttle body, any good cam recommendations?

 

[AM18195]

90mm tb on a n/a car will destroy your torque fyi

 

[slayton93]

right now i have a 70mm throttle body, should that work with the victor jr spyder intake or should i bump up to a 75mm?

 

[AM18195]

A 70 is perfect for a n/a 5.0

 

[slayton93]

sounds good, thanks for the help man

 

[YLDPONY]

I will agree that a 90mm TB is overkill for this specific application, but why would it decrease any torque? I don't agree with that.
