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.
Intresting, can you share more info of the water cooled intakes?
What sort of info are you interered in?
All my cores come from Bell Intercoolers in San Antonio Texas.
I build both street and race versions
Street versions i keep within a realistic hood line. Race versions are hi ram design and require hood cutting or large cowl hoods.
pictured here is a 2000hp ltx (gen 5 direct inject lt1/lt4) race intercooled intake on Roho Snyper gen 6 camaro. He will be debuting this new intake this weekend at StreetCar TakeOver Atlanta.
he was prior to me on a procharger air air setup running consistent 9.2x at 155 mph. Air temps were soaring to 200f by the end of the quarter. I should be able to keep his temps at or below ambient at all times
The bottom intake is our gen 5 ltx street intercoolered. It will clear a c7 base hood and features a core that will support 1500hp
Next week i should be building a cathedral race intercooled intake as well. I will post pictures and videos as they come
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!)
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
As a retired Aircraft and boiler weldor, Kudos to your weldors that is some awesome Heliarc work. auto correct says I spelled Weldor (a person who welds) wrong, a Welder is the machine that does the welding. Pet peeve of mine

Thanks buddy!
My wife is going to welding school come Jan to help me out.
Tired of running 70+ hour weeks alone, with her help I'll get a second tig (Dynasty 400 for her, I already have a Dynasty 700).
Things keep going well we will be a sponsor for Holley Ls Fest Vegas next year. Also look for us at TX2k next year.
Group buy testers special pricing (normal $1560) at $1150 each!
PM me here, text me 832 392 2848, or facebook me at James Carolyn Goertz
Only 3 slots available. HP Motorsports in Katy wants 2 of them but it is first come first serve as I told Jay and he hasn't paid me yet. So get in now (only 3 at this price) or wait for the price to go up!
Finally got a overlay dyno chart out of my customer Roho Snyper (his facebook name)
Blue line is the holley hi ram on his procharger f1x blower and race air to air intercooler
They approached me to build them a custom air water because they were seeing 200F at the end of the quarter mile.
With my intake they stay at ambient with water only (1.5 gallon total water system), with killer chiller on 15 below ambient.
Tune is nitrous tune but running boost only so rich and no timing in it.
