Nitrous

[gub]

How much would be a safe amount to run on a stock motor?

Less than 100k miles. 8.7:1 compression.

a 5.0 mustang stock , you can hit it with 150 all day long its all in the tune

How do i tune it with a carbed motor?

How do i tune it with a carbed motor?

timing and jetting on the plate/nozzle , and dont forget 1 step colder spark plugs

 

[gub]

With the timing would i have to advance it or opposite? And if i were to run nitro, would i have to upgrade the gas too?

 

[bigg]

-2deg for every hundred
use premimum gas

 

[gub]

What if i use premium right now, will it effect anything?

 

[bigg]

nope , just keep usin it

 

[gub]

Is it safe to run premium in a 8.7:1 comp motor?

 

[SuperStang90]

its safe to run premium with any motor....but pointless if dont have enough compression or timing

 

[gub]

Oh alright. But what did Bigg mean by 1 step colder spark plugs?

 

[bigg]

ok , lets start here

do you have forged pistons ?

 

[SuperStang90]

ok , lets start here

do you have forged pistons ?

haha yes that would be a good start

 

[gub]

No its all stock except for intake and carb

 

[bigg]

imo dont spray it

 

[SuperStang90]

No its all stock except for intake and carb

what is it? if its an 87-91 5.0 its forged stock

 

[gub]

Its a 68' 289.

 

[igotaneed4speed]

Its a 68' 289.

If it has orginal internals w/stock rod bolts and ect..

I'd be scared to hit it with more than 150 and turn it past 6500... keep it under than and you might be able to get away with a lil more.

Better have a spot on tune with them cast pistons one ping and its bye bye

 

[gub]

Whats a ping?

if i was you, i wouldnt use the nitrous..
