[05ghost]

How much boost will a stock 3v 4.6 hold safely? Not looking for high horsepower or torque Numbers, just. Want good power for my daily till I can build forged shortblock ? Thanks guys

Commonly accepted numbers are about 450-500 with some caution and a little bit of luck.

I'm.looking at running a t67 at about 6-8 pounds very safe its my daily

I would stick to 6 psi on a stock rods/pistons.

Are you fucking serious

 

[NitroPsycho]

Lmao... Search?

 

[HEMI LOL]

don't let these guys fool. you. the stock rods are safe to 650whp. id get a T88 and turn it up to 18psi. just adjust the sct tuner yourself. no need to even dyno tune it. you can probably even run 87 octane too.

Bent a rod at 7lbs. On any motor built or not can break. On my built motor i dropped a valve and destroued the block. my 2 cents.....

How much boost?

With the right cam profile, 50+ psi

Been running my stock bottom end for over 4 years with Whipple-HO @ 11 psi.

This ^^^ make sure you get a good tune.

The key is to also make sure your running enough boost. Between 6-7 pounds and your guaranteed to be safe. Going under 6 or over 7 and it WILL come apart. 6.5 pounds is obviously ideal......

OMG

I know what you're thinking, bro.
FINALLY! a thread about how much a stock 3v can take!

THe motors are only built and engineered for 300bhp..., however I run 10lbs, with a safe tune, but I don't beat the shit out of every time I get in it either, I also understand it could go at anytime. If you are going to modify your car you better have a backup plan. I've heard 7 or 8 is idea, but still not guaranteed.
