LOL, so self proclaimed smart guy has no splain for my question, other than calling names.

A real smart guy could splain this **** to the class.

You just can't make this **** up.

 

Cool man, Who do you work for? A good friend of mine from college works for Eaton's supercharger division in GA. I formerly worked for Mann-Hummel designing NA & turbo intake manifolds. We occasionally debate the subject matter because he's a ford guy yet respects GM.

 

Still has yet to post proof of his claims yet has nutswingers coming in to defend him. Only on ls1 tech lol

 

lol...I won't waste my time. It'd be like Sheldon Cooper trying to teach theoretical physics to a chimpanzee.

 

This is how you post proof. Here is a 376ci ls3 vs a 330ci 4v with c-heads. Both of these are n/a and the 5.4 dominates

 

I don't work for any speed shop. used to work as a mechanic, and at a muffler shop where i made headers for racers in the local area... I been doing this stuff since 1985. I do it for fun and to make things others don't. try to be different.

i'm probably done with forced induction. Cleveland power has me interested.

I have to put the CJ stuff and add cams to the coyote so I can sell the turbo car and build something else. probably a big inch fox Cleveland. simple and analog. may just store the turbo in case the kid wants to race it when he/she is old enough.

I have a kid on the way. priorities. im definitely going to teach the child how to fab stuff.



all that stuff makes me sound like a ford guy.

im not. ive built all of them for power. I guess ford is the underdog really. if I had to win money or had money at stake BBC is all I would consider building.


im not a fan OF LS power because at extreme power and build levels its too unreliable. lifter issues, rocker issues. im just not comfortable with the design.

if I am going to lift a cam to .6-.7 I want a bigblock head and part strength. size and weight mean ZERO to me. my engine stand is bent by a 400 Pontiac I built. awesome platform the 400. heavy.

 

Now you are a ******* genius, but can't splain why an engine with less cubes spinning the blower rotors at the same speed as an engine with more cubes makes more power? LMAO!

All your book smarts must really pay off in the real world. Keep up the good work... genius...SMH

 

to be fair, more info is needed for a precise answer.

truly cubic inches has VERY little to do with power.

if I take the late model gt500 head/cams and place it on a smaller or larger engine, peak power potential is the same at a different peak torque rpm.

what changes on a forced induction engine is the pressure ratio it takes to achieve than same power.

 

Howabout you open up the link I posted and do the math yourself?

Because efficiency.

 

So the 5.8 mod mota is more efficient than the LS9....got it and thanks!

 

What is your education level? You're responses are on par with an 8th grader...and that's being generous.

 

I guess you need to have someone else do the math for you then islander... On the 5.8 at 15 psi the 2.3 blower is spinning much faster than on the 6.2 ls9 at only 10.5 psi... So the 5.8's blower is spinning much much faster and only making a tiny bit more power making it less efficient even with its fancy dohc and being the size of a small moon... Poor Islander, just can't win can you

 

Its called Having *urd for brains

 

Show me the math genius.
That ain't the math MAC2.

Show the math at the same blower RPM....boost psi has nothing to do with it.

 

no it is not more efficient.

a pent roof 2 valve ls3 flows about the same as your gt500 head. very close to the same.

a ls9 uses 10.5 psi to make 639hp.

gt500 uses 15 psi for 662.

if the ls9 used 15 psi it would make more power than a 2013gt500.


smaller engine needs more boost. if you drop the 2013 gt500 boost to 10.5 psi it would make 475-550hp.

as a matter of fact the ls9 makes 755hp with the stock blower at 15 psi.

not sure why you are arguing that. its fundamental dynamics.

 

you are wrong man. out in left field. i really hate to waste my time. i guess ill have to give you another class on boost fundamentals.

i have a feeling that is a waste of time. i could stick it in your face and youd troll. IMO

 

So show me the math....it's easy ain't it?

LS9 vs 5.8 mod. Same blower speed. Don't forget to carry the 1...lol

 

You are so retarded you can't even understand that my post meant it takes more blower rpm for a 2.3 tvs to supply the 5.8 shelby with 15 psi than it does the 2.3 tvs to supply the 6.2 ls9 with 10.5 psi... You keep bringing up MAC, I have no idea who he is, but it seems you have a thing for him... Or your just too much of a moron to come up with anything else after everything you post gets shot down?

 

Still no math to show what power would be put out with those 2 motors at the same blower speed?

Not that I expected MAC2 to be able to do it anyways. lol

 

Here you go Mr Monkey... Play with this all you want
