Same computerized concept as CNC machining prior to the physical work. No fixtures required or chips to clean up either.

Unreal

I have a 3d printer and could print them if you send me files.

Hey guys, I'm a bit of a noob on this stuff. Can someone please explain to what the benefits and possible trade-offs for doing this could be? Why wouldn't fast just make them like this to begin with? Why does it look like they will be offering an option of 3 sizes in th future?

Unreal

Different size runners excel at different power bands. Short runners give up low end torque for high end power. It is all a tradeoff.

I've been saying this forever! I can't believe no one has 3D printed any different runner designs for the FAST

ian08

prolly its cause they have a patnet on the removable runner design nobody could sell them with out lawsuit and i wouldnt even know how to send files to anybody for a 3d printer im not good with computer stuff

ian08

Here is 2 of them done I still have some finish sanding to do but a good any idea how they will sit

SHovV

Looking good

ian08

its coming along very slowly its so much work so much sanding but that guy u put me in touch with that used to work at lmr has been helping alot hes saying its looking good so i hope it makes more power i prolly wont post any more pics till im done not much more to see i just had to get a couple ruffed in make sure they would fit with the top shell

SHovV

Good deal. Lookin forward to the finished project and see where you gain and lose in the power band

When the hell is Fast suppose to release the LS7 runners?

Ive been wanting to get a set since I first saw they were introduced over a year ago.

robz

I'm assuming you want the rpm band to be shifted to the right without losing power?

Ironically my cam-only setup with a fast 92 peaks too high for me 7300+ with the standard runners.

ian08

no eta right now i they dont even care not a big anuf market i quess

ian08

yes i do i have a cam when designed on engine dyno with single plan plane makes power to 7600 and in our cars with fast intake peaks at 6400 it carries the power decent till 7k but i wana peak at 6800-7k maybe shift at 7200

Unreal

If someone makes the file, I'll 3d print some up.

Or someone just buy a 3d printer, they are stupid cheap now days.

ian08

Final product hope it's worth all the work I'll make a new post with results in a month or so

Turbo2L

Well done, sir. Hopefully it was worth the effort.

olddragger

Sir you are a true hot rodder!

SHovV

Looks good Ian!

ian08

me to cause if its a flop i am going to have to break down and buy one of those ugly MSD cause i had to plastic weld the runners into the lower shell
