T-REX vs. MS3 on the track.
T-rex After installing 3 different cams in 3 different cars. The out come is this.
The F-14 in a 98 TA with all mods shows 395 RWHP
The MS3 in a 99 TA with all mods show 398 RWHP
The T-REX in a 02 SS with all mods show 432 RWHP
All cars had factory heads, pistons and all common bolt ons.
All Mods on the cars was headers, intake, lids, true dual X pipes and of course the package of dual valve springs, locks and retainers and push rods.
The only different was the ss had underdrive pulleys. These are the cars I have done and seen first hand on the Dyno's. Just remember the T-REX is a race cam and the only down fail I have seen with that cam is Plugs and maybe a annually tunning..

For me its unfair comparision since every car is different , there must be some good factors so we can make this fair , and some of those factors are gearing , weight , tuning , driver , stick or auto .... etc .
I would probably compare the 2 cars if they were build equally , and when I mean equally , cam only plus the factors that i listed above.

I know there is prob alot of remarks about this but that when you look at the fastest cam on cars, ALOT of it has to do with the raceweight, the heaviest car weighing in w/ driver 3500, but the majortity is about 400-700 pounds lighter. Thats makes a HUGE diff when you start comparing times and mph's.
Also the heaviest car of the bunch runs a 4.5X rear gear to get that porker out of the hole quicker.
You really needed the same car, and similar weather to truely determine what works best for that car, odd are though T-rex should beat the MS3.

Haha, holy old thread. I find it amusing when people start throwing in new cams like the vindicator and MS4. When this thread was created 2 years and 8 months ago those cams didn't even exist. I think that shows how well the Trex really works. Even after a few years people are comparing new cams to it. I recently bought a short block with a T-Rex in it. I plan on sticking it in my 93. It should be fun in a 2900lb race weight car.

Actually, you have to rev the MS3 higher than the T-Rex to make best ET. The reason why is that the T-Rex has better dynamic compression and builds better power under the curve. The mid-range torque is superior because of the narrower LSA and its top-end speaks for itself. The MS3 is a revver. The T-Rex is a monster.
Just look at the cam-only ET records and see what cams dominate the top. Either T-Rex's or T-Rex clones (like LS1 Joe's).

I am the one who designed the T-Rex. Actually with some of the latest design process I am doing now, I just did a cam that will step on either of them pretty bad...It has a wider power band, and revs higher. Details to come...

You have me excited. I'm looking forward to something like that since I realized the cam in my engine I bought isn't a T-Rex.
It will be available after January 1st. As an FYI I just tested a cam only combination (stock 241 castings, LS6 Intake, 75mm throttle body, 75 mm MAF) against a combination that had a set of ported LS6 Heads and a cam larger than one of the one's listed in this thread from one of the more popular vendors around here, a FAST 90, 90 mm throttle body, and a 85 mm MAF.
My cam only deal made more low end torque, the same peak power, and actually carried higher in the RPM band. We shut the pull off at 7200 RPM because this was a stock short block! This thing was still pulling...

Things have changed with me. It will be more clear in the next week what I am talking about...
As far as the cam is concerned: P/V will be VERY tight. Either flycutting or sinking the valves in the heads (or aftermarket heads with better valve drop) would be a good idea. Honestly, the P/V will be similar to a T-Rex, but it should definitely be checked in any case.
This cam will make similar peak numbers to a T-Rex or MS4, but the power will start 700 to 1000 RPM sooner and carry MUCH further. It also will be VERY happy with spray. In fact the only issue with using this cam with spray will be getting the car to hook. This cam will hit VERY hard off the line.
I will start selling this cam Jan. 1st.

It has been optimized for a long runner intake.
The cams I am doing for single plane applications are different. I have a couple of cams for this type of application, but keep in mind that if you use any of the 'popular' off the shelf cams in a carb application it won't be optimal. A cam for a single plane intake, by necessity needs to be very different than what is done for a long runner intake.
