A Couple Stock Specs ?s

true that the TB flows at least that well, but the downpipe interferes with the flow capability, lowering the power quite a bit. those numbers would be correct for a well-thought out and proper exhaust system.

I hear ya there, but if going turbo, the restriction should not be as much of a factor? or am I way off there?

Stock 3500 is 65mm, so identical to the TCE Billet TB.

i thought i read that somewhere before... wasn't sure if it applied to the regular 3500 or just the VVT flavor

Stock 3400 TB is 327 @ 1.5hg (56mm). Stock 3500 is 65mm, so identical to the TCE Billet TB. Stock 3500 is drive by wire so you can't use it.

Ya, sorry, I realize I cant use the stock 3500, however, though the 3500 and TCE TB are same size (65mm) would the design of TB not (plate etc) effect CFM?
not all 65mm TBs would have same CFM?

[robertisaar]

unless there is a very significant difference in the design of the plate and shaft and entry/exit, they will, more or less, flow identically.

Ahhh, I was reading the opposite, but then again I read it on a site that designs and SELLS Throttlebodys, so I guess I should have taken that into consideration lol,
(think it was accufab or something to that effect)
So if going Turbo, the exhaust would not greatly effect the 440CFM of the TCE 65mm TB then?

You would have to flow each throttle body to get an exact measurement. I don't find that information to be the least bit useful, unlike flowing a head with the manifolds and TB on there.

I am lost on your exhaust to tb size reference.

[Weatheralls Auto]

i'm assuming you are going off of my stuff? i have a 3500 setup in there already done...

but i think you have it right now.

EDIT: may need to tweak induction flow a bit more to get the stock numbers...

I was refeering to what Robert posted,
The restriction of the downpipe etc would lower the Airflow for use in DD,
I am asking if that would still stand true if using a Turbo?

[robertisaar]

depends on how well the exhaust before and after the turbo is made. no horrible 90* bends and being properly sized, it can allow the motor to breathe as much as it possibly can.

[Weatheralls Auto]

Cool, gotcha!
Appreciate your help.

So I need to find some turbo headers then lol.

breathing: good for people and engines...

Better if I could weld lol, my welds look like paintball splatters!

it ain't gotta be pretty to be strong. my monster strut tower braces are proof of that. although in that situation, i can cover them with body filler and no one will be the wiser.

[Weatheralls Auto]

Haha, true, dont think body filler would last long on headers

Thanx again for your help, I am sure to be back with more ??????s

JB Weld
that'll stick for all of one heat cycle.

[Weatheralls Auto]

so I'll just never shut her off then lol
