We here at Goertz1 Performance Racing Organization (G1Pro) are gearing up to release our line of cathedral, ls3/lsa, and c7 intake manifolds.
We currently offer a full lineup of gen 5 direct injection ltx intakes however these winning designs are in the works of being ported over to all lsx engines. Cathedral and Ls7 parts will be the first to roll out and should be ready for shipping by Sept 23. Ls3/lsa will follow that.
We have many different styles available. Some oem hood friendly bolt in options as well as our Hi Ram Terminator line. We also offer air water intercooled options (up to 1500hp under stock hood) using only the best cores from Bell Intercoolers.
Id love to see a comparison between this and a FAST 102 intake manifold.
Have one I'm building for custom mast 285 cathedral heads. Customer has already popped 3 fast intake at 30lbs boost and ready for something bullet proof.

Cathedral vette intakes (first proto batch) has shipped and final design with improvements are going into production within next 10-14 days. All Cathedral group buy special pricing has been used up.
Currently taking pre-order on ls3 group buy for vette intake manifolds (normally $1400, gb special $1050!)
After ls3 will be ls7.
For Cath/LS3, LS7 and LTx we currently have billet runner options with full radius air horns 5axis cnc mill in the works. Also for LS7 we will be releasing a full billet for both the tall deck and standard deck within 3 months (pm for special pricing on that, took first order today!)
Sub for a possible FI intake option, lets hear more about the A/W intercooler option and its effectiveness for a Street/Strip Boosted Car? Pricing for the LS3 setup?

The setup i did for Roho Snyper featurers a 1700hp core dual pass design. It is the same core and plenum volume as what is on the cad cathedral setup but Roho features a 5" runner while this cath features a 6"
Roho car has maf pegged at 250F while the post core iat is reading 81F
On the dyno with killer chiller off temps never exceed 91F
With killer chiller on 15 below ambient. This is with only 1.5 gal total of water in his system so i would say it's dam good for a street strip car. For a mile car you'd deff need more than 1.5 gal though maybe 5-8 gal.
The Boostworks Mustang 2k whp we have a 24 total gal water tank
We keep having requests for Billet Intake Manifold so started the conceptual work.
have 1 order for tall deck ls7 billet intake right now so they will be first to roll out followed by ls7 standard deck and ltx direct inject and ls3.
Runners are adjustable from 4" to 7" with 1/2" increments. The taller plenum accepts an upgraded air to water core supporting 3000whp with ease for those really serious people. The taller intake will be right at 10" tall from valley plate while the shorter staying at 8.5"
Cathedral Vette, features 6.5" runner with cnc vstacks, expect huge mid range power while holding hp to 7000rpm. Clears c5/c6 oem hood. C5 may require cowl notch for fuel rails
$1750 shipped with wrinkle black powder coat
$1500 shipped bare aluminum
You sure you don't want to loan one out for a 3rd party dyno comparison?
I'm about to do a stock intake vs ebay fabricated intake on a quad turbo 4.8 on an engine dyno..
Have plenty of local shops (LMR, GFORCE, HP, HHP, POWERFAB) that all do testing for me anytime i want and i don't have to worry about getting the part back.
Problem is i never have anything in stock lol sells as fast as i build them.
Going to attempt to get ls3 hi ram together for powerfab to throw on 1300whp zl1 tt gen 5 for Texas mile

Yeah? So I take it you have LOTS of comparison tests you can show us.
