I’m looking for information on TMP carbs.
I see they were developed by Troy Peterson of Monterey CA.
From what I understand is he used Weber metering blocks / power plates to make a Holley more tunable.
Any additional information is welcomed.
I’m curious if these Weber power plates are still available and if anyone has had real world experience with these carbs and or plates.
I see they are thicker and require longer float bowl screws and fuel line needs to be longer also.
Some of the info I have found so far.

I am also starting to search here and am finding some interesting things about Troy to say the least. LOL
Thanks in advance.
Hello, this is Troy Patterson, owner, operator of TMP Carbs. I’d be happy to answer any questions you have. I continue to build Weber Power Plated carburetors, namely my VenturiLess and Six-Packs with the upgrade option of using Wer Plower Plates in place of Holley style metering blocks.
I’ll give y’all the short breakdown on the Weber Power Plates and why they are superior to all of the Holley style stuff including Braswell and all the rest: 1) they atomize the fuel more uniformly and consistently resulting in improved throttle response, torque, horsepower, and drivability; 2) main jets and air bleeds, AND idle jets and air bleeds can be changed in about five minutes out the top of the Weber Power Plate.
I acquired the complete Weber Power Plate inventory from Edelbrock in the mid to late 1990s and sat on them while I was both learning how to make best use of them on a Holley carburetor, and was at the time involved in a nearly decade long research and development project developing improvements and upgrades for the Holley, then integrated the Weber Power Plate into the re-engineered Holley. Though I developed the VenturiLess Holley by 1998 I introduced a lesser version in 1998 called the Premier Series (4150 and 4500) which at $1600 (in 1999) I sold for twice what Holley and everyone else was getting for their top of the line 4150 carburetors at the time.
About 15 years ago I introduced the present version called the VenturiLess which features adjustable linkage ranging from full 1:1 to progressive settings (everyone I am aware of runs them in full 1:1) and retails for $2200 for the 4150, and $2500 for the 4500. I have happy customers running the VenturiLess at 1100 cfm and 1200 cfm on engines as small as 305 cid and 302 cid in heavy road race cars such as a 1970 Mach 1 and 1965 Falcon and on engines exceeding 500 cid and 1000 horsepower.
By the way, I build wicked Big Bore (big cfm) Six Pack set ups using non-original Holley two barrel carbs. My larger cfm versions make more horsepower and torque, especially on high horsepower and/or stroker engines.
The path before me has always been salted ahead of me as is clear based on the OPs comment. Despite this, I have always gotten results and made my customers go faster ranging from Bill Elliott’s Winston Cup program 1995-1997 where he ran two of my developments and clearly had the dominant car to NMRA Edelbrock Hot Street entry of Michael DeMayo and Ben Mens of (Rousch Racing), to circle track, mud pulls, and so on.
Although, I had been selling the Premier Series for a few years by early 2002, I participated in the Engine Master Challenge with Nelson Racing Engines running a conservatively estimated 1100 cfm Premier Series (actually nearly 1200 cfm) on Nelson’s 359 cid SBC that was pulled from 2300 rpm WOT without problem. If that is not a testimony to the Weber Power Plates superior metering or the design of the Premier Series turn VenturiLess I don’t know what is. Tom and I finished 7th out of 50 entrants.
Anyone can find videos of my carbs in operation on my TMP Carbs YouTube channel of the same name. Be sure to checkout the small block with a 1200 cfm VenturiLess taking WOT @ 1500 rpm in first gear.
