LT1-LT4 Modifications - special way for porting LT1 intake manifold

some one showed me pics of how to port the LT1 intake manifold. it is taking a lot of material from the roof of the LT1 intake manifold. i missed the link to that post with the pics in that post. any one can show me how to port the LT1 intake manifold with pics. because with my friend's 1994 LT1 A4 camaro it dynod 317rwhp although it was modified with complete heads/cam mods but the intake manifold was lightly ported not as as the way i saw in the pics in the post i mentoined above. with the way i saw in the pics the car might dyno from 380 to 400 rwhp. any one can show me the pics and how to port the LT1 intake manifold? it is porting the roof area.

doubt that much of a hp increase but a good 10 maybe 20?

If you can add 60rwhp from an Intake Porting, I want to see that shit..:eek:
I port-matched my Heads and Intake to the Gaskets, and that might get me 10-15rwhp..

I ported my Valve covers and made an xtra 39 to the wheels.
I'll post pics later.

what i saw in the pics was big port cloggings clog the port from flowing well and i'm serious about it. i just missed that link to the post i'm saying not gasket matching but a lot from the material was took form the roof area from the LT1 intake manifold.

I know what your talking about and its not really worth it. Some people get carried away when porting an intake. They think it helps but all its doing is making more busy work for themselves.

I changed the Muffler Filter and got an extra 25..
:jest:

The porting he's talking about has been shown to increase the total intake flow (manifold bolted to head) by about 15 cfm. A head porter can spend days trying to find a gain like that.

Yeah, I ported my PCV valve and picked up 100 rwhp... :)

It's a Supra, they pick up powa easy... :razz:

You may want to consider porting your air conditioning ducts for an incresed air conditioned air flow. :)
