Ok guys 5.3 boosted for real?
 

Hey it takes quite a bit to get a 6.2 with a whipple or maggy to get to 550-600 HP
Then you see a vid like this and go really? I would like to her opinions if this actual or BS or somewhere in between.
:popcorn2:

What gear, locked or unlocked. Probably locked.

I would say that at least 95+% of the time Chuck tunes vehicles for e85 only. That adds a little.

And it also depends on the mod list. Headers, studs, pulley size, cam/fuel lobe?

I would think with that number, it's 12-14psi on e85 and some fat timing.

Safe? /shrugs

Get you a ls3 top end and see what happens.

An LS3 topend on an L86?? Two different motor platforms.

I say BS on a 5.3....!

I'm gonna raise the bull shit flag on that one as well.

I wouldn't doubt it. Paul from magnuson told me he was an injection pump swap away from 700 with his 5.3. It's got to be an E-85 tune and did you here it lope before the pull?

Isn't Allen P way over 700 now?

647/591 was the last post I saw.

TTRaydo made like 650/600 with a one-off twin kit but spit a rod out the block not too long later. I suspect tuning/fueling on that one tho.

Yup... 6.2's are junk. Should all run 5.3's cause they rule the interwebs and that pathetic joke of a "performancetrucks" facebook page lol. Realistically a 6.2 with a cam, pump, injectors and then boost should do better than that.....

e85 ?

a local guy claims 700 hp with his DI 5.3. Procharger and nitrous. I raised the BS flag on that claim and do on this video too.

733 is a lot of power. no doubt about it

allenp made 700hp Procharger

post up links to it :redneck:

Mine made 735rwhp
stock bottom end 5.3 with a cam
e85/meth on 17psi
D1sc blower

For fuel system it had a bigger fuel lobe on the cam, lt4 injectors/lt4 pump and the CPR lowside fuel system
3.5 pulley

can't wait for the new project :devil:

wow very impressive.

I can't exactly say I don't believe it.

I think Chuck is kind of full of it sometimes. He's a social media guy... take it all with a grain of salt.

On my 5.3 i made 534/560 whipple 9lbs meth headers tuned by matt sorian
Mustang dyno

I Lol'd at this..

x2...

x3.

lol.
