porting for a friend for his project truck. spent about 4 hours on it today still need some clean up on the ports and get everything blasted and coated. still got the plenum and blower to port. ill post up more pics when i get around to it next weekend. if the thread is still alive.




there is quite a bit of material that comes out and im still 1/8" away from the sealing surface.


all of the rough porting done and the flange surfaced.
just needs some hand sanding now and then gets heat tanked.

 

sheesh, i never thought there was much to port, mostly just smooth it up. your friggin close to the inj port lol

 

There's nothing to seal there, so you could grind right into it if you want as long as you don't get up around the step where the injector seats.

Looks like a good project, just be wary of porting the blower. You don't want to mess up the port timing of the blower. Every test I've seen with "professional" ported blowers loses power until they speed the blower up, and of course the unported blower would have made more power too with a smaller pulley, so the test articles are worthless.

 

im just going to take it apart clean it, clean up any rough transition edges and clean up the outlet. then its all getting powder coated if mark figures out what color he wants...

 

i didnt port over to it i just rounded the transition to force air to the injector. if u want yours done let me know.

 

the benefit of a ported blower would be lower discharge temps.

 

yup. ive heard there are greater gains from porting the lower intake than from a ported blower.

 

if ya ask me the way to build the system would be to use an ammonia based intercooler. imagine the temps you could pull off. psi = temp in its own system.

 

Im building a 302 right now, I've spent alteast 20 hours porting and polishing the heads. I tell ya what, porting is no easy task, damn cast iron!

 

the real gains to polishing the lower and mid plate are the lower air temperatures

 

I really need to do this to mine. Possibly this weekend...

 

It get a lot easier as you do more, probaby takes me ~4-5 hours to port E7 heads (not including disassembly/cleaning/assembly). If you are polishing everything to within an inch of its life and trying to make it all look perfect don't bother, you won't gain any flow and thats a whole lot of extra iron dust to stay away from. Its good to polish the chambers for heat retention, but the intake ports are actually better with a slightly rough surface.

 

is this mark's, paul?

 

yup

 

lookin good dude....still have no clue what color i want but its either red or black....cant wait till all this is done.....THANKS AGAIN PAUL
