"porting as&m runners"
hi there guys,
just wandering is there enough material to port the as&m large runners?
apparently the as&m runners are 42 mm in diamater standard!
the first intake runner size is 45 mm diamter and ken@ first intake said they can be ported to 1.9" and there runners with plenum/base flow 230cf!
how hard/expensive would it be to get some one to make up a set of say 2" diamater runners?
the as&m runners are $435.00, the first intake set up is $999.00 and so on!
if you had large runners say 2"diamater and the plenum ported to match along with the base ported all that size, would that let the tpi breath past that wall of 4,500/5,000 rpm do you think plus more flow& revs?
you see i like the wow of the torque power of the tpi only much greater would be nice,and with more revs would be better!
just wanted to see what you all thought of this thats all!
thanks

Standard "fast" is basically the same diameter as AS&M.
1.9" is 48mm, so there isn't a real major size difference (ported "fast") from the AS&M.
How much $$ is the "fast" system?

The "Wall" is not caused by the size of the runners as much as it is by the length of the runners. In order to raise the RPM band you need to shorten the runner length. The only runners I am aware of that allow you to do this are the SLPs. Although they dont flow so well out of the box (they are really no larger than the standard runners at their centers) they have tons of room for enlarging them, as well as allowing you to siamese them as far down as you care to, shortening the runner length and raising the RPM band.

hi roy,
thanks for the advice mate!
so seeing ther slp runners are shorter in length which i didnt know then,
if you port the hell out of them and siamese them then they could be quite an attractive propsition as you will have some torque and higher rpm then?
what diamater do you think you could port them out too?
could you port them as far as the as&m and first runners do you think?
what is the flow the slp runners run at do you know?
also do you know what length the slp runners are?
thanks for your advice and time!
cheers

The biggest you can get them is an average of about 1.75". (about 45mm)
Heres a pic of how you can siamese them to shorten them.
This is a pair I was working on, they werent done yet but you can get the idea. As best as I can measure I am going to end up with a total runner length of just over 10 inches and an average diameter of almost 1.75" versus 13.5" and 1.5" in a stocker.
I am putting it back together tomorrow, I will let you know if it works as I expect it to.
One more note. This job was a major PITA, not for the faint of heart.

Here's a short clip of what my large tube runners, Big Mouth and ported plenum can do. Watch and listen

5,700 rpm and 125mph. in 4th gear. TPI can still be fun on the street.

Any "still" closer pics of that dyno graph? What I could see, it looked to be very smooth and broad...

Just check "My Photos"
The GTech graph shows that the car on the 1/4 mile continues to pull. I have kept my foot on the gas until 120mph on the track. I trust my brakes

No "WALL" on that graph.
btw, Are you the 12.50 car, or the 13.0 car?
Is your car "chip" tuned? or no? Just curious.

I used to get 1.8 short times, now I'm lucky to get get under 2.0
I'm looking for a 12.7 next summer after a new clutch and few other tweeks here and there.
I used mostly TPIS parts and used their stage V chip programed for the mods that I have done. I think the tune is right on and on the first try.
TPIS is a little pricey but I like to support local merchants.

Nothing wrong with using what works.
It's refreshing to see a car that runs very well with TPI, even though most seem to preach that it CAN'T. I'm sure that your car is an absolute blast to drive. Well done.
They definitely got the tune on...Man, you couldn't make that a/f line any smoother without a straight edge, lol.

Thanks it is a blast to drive.
Good luck with your build. I'm curious to see what your results will be.

hi guys,
im thinking may be i can get my local guy i know who does alot of custom performance car mods and exhausts could possibly make me up a set of new alloy mandrel bend 2" diamater bye 10"-12" long intake runners and then port the plenum and base to suit!
im sure if done rite they will give killer torque and some nicer higher rpm,s!
what do you reackon guys?
i love lots of torque but more of the mid- near the top a little would be nice though!
cheers
