Default Shorter Runners for FAST Intake!!!

Saw FAST intake @ PRI YESTERDAY
They have replacement-removable runners for their
102 Intakes . Two Versions short and medium, eyeballing
I would estimate 6" & 9" could be +- 1 " either way.
This is great news! existing Fast owners can just
Change out runners rather then Getting the MSD,
Saving considerable $$. Thanks to MSD for putting
The Torch to FAST's ...
Should be available in next 2-3 Months if not sooner!

Explain the benefits of the shorter and longer runners in terms on a NA setup.

Yes, thank you for the posting. I am anxious to see what the independent dyno reports will look like.

Still haven't seen a comparison of a fast 102 vs MSD intake on a heads cam ls1.

Default Shorter Runner Application

MSD is releasing LS7 first ~ 30 days, LS3 2nd ~ 90 ish days, followed
By Cathedrals 180 days according to the person in charge at MSD
who was at PRI. FAST has a patent on removable runners so MSD
had to base their design on one length. The MSD will fit under it's corresponding engine/vehicle.

Billy the man in charge at COMP/FAST who was also at PRI said
LS3 & LS7 runners would be available very soon within weeks.
I have a Mamofied Fast LS3 & Had intended to get the MSD and have it ported
By Tony as well for my Big-Bore TFS LS3 build but as the FAST runners
Will be available sooner and less expensive plan to get the HP runners
And perhaps the race runners also and do some comparative testing
Hopefully by the end of March.

In would expect FAST to have runners for the Cathedrals as well in order
To compete W/MSD. I do not know if they would fit the 92 or just the
102.

Lingenfelter has tested the MSD on a 573RWHP 427 CAMARO &
Gained 36 RWHP & 16 lb ft versus a ported aftermarket
Intake (FAST). And I saw a Dyno Graph @ the
MAST booth (PRI) and they Gained 20 HP ( Crank?) and area
Under the curve on one of their engine packages. They guy
Was supposed to E-Mail me the graph but some how I did not
Get it. PRI is the Ultimate Hard-Core Engine/Mechanical Systems
Etc. Car **** experience.
( Next to Racing of Course LOL )
Every Car-Guy needs to go at least once!

I'd love to see that too, but I'm not going to hold my breath. I think they need to rename the MSD intake "blue *****".

So the short or medium runners on the regular FAST 102 would be like that of the FAST 102rt?

FAST RXT truck intake is much taller, so runners stand up taller.
If you look at the medium or HP runners in the photos posted
They are laid down at a flatter angle so they fit under the cover.
The Race runners being shorter are able to stand up taller.
I plan to test all three on my Engine build, hopefully by the end of
March 2015.

Shorter runners will move the peak rpm up, and longer runners will lower peak rpm while giving it a more broader torque curve. The problem with this style intake is there isn't near enough plenum volume to take advantage of the runner length.

Curious how the runners look on the MSD intake and if they are more like the FAST short or medium runners.

Runners on MSD are closer in length to FAST HP or medium length,
Not quite as laid down, but definitely more laid down than the shorter
Race runners In the FAST, remember the MSD still has to fit under our
stock hoods If they want to sell them in enough volume to pay for development. But it is great that MSDs entry has forced FAST to step
Up their game!

Well, I guess the million dollar question is does the new runners FAST makes for their 102 outperform the MSD Atomic intake?
