Forgot about these. Were these better than the Super Ram? Cool looking for sure.
In the "Ten times the tq" article, the Super Ram did better...on a pretty aggressive 383. I think on a milder 350, the T Ram would provide more area under the curve -since that's what it was specifically designed for. SLP was attempting to maximize performance for an RPO package on the Firebird, using available/certifiable stuff. That meant a stockish 350 at best. Using the L98 as the starting point, with ported 113's, mild roller cam, shorty headers and single exhaust, AND being CARB certified for OEM emissions, it made 350 NET hp and 390 Net torque. Damn strong numbers for 1991 when an LT5 was 375 hp/385 tq.
I've also read in the past, that on a stock L98, just the intake swap alone was good for 50hp. Not sure how true that is -it may be embellished some...or a lot.

All the 180 degree turns for the airflow within the T-Ram becomes a restriction. SR has big plenum and a straighter shot at the intake valve.
Show us where that's been tested/proven.
In reality, the interface between the head and runner is better in the T-Ram, than it is in the Super Ram, which has the same poor head entry angle as any TPI intake.
FYI the air only makes 1, 180* turn and it's in the plenum where velocity is slow/meaningless. That turn is no different than the turn made in virtually all '80's Mustang 5.0 intakes. How do they all work? The point is that "turns" in the plenum aren't often a "restriction" b/c velocity in the plenum isn't meaningful.
Well? Then it sounds like you're making **** up. I feel that the biggest limiting factor for the T-Ram is the cross sectional area of the runners. They are sized for a stockish 350 and thus, I feel that it comes up short compared to the Super Ram on the one test that we all reference. Note that I said, "I feel"...b/c we don't know for sure.
Yeah? Quote it. What have I "made up"? Did I even make a claim?
Found it! It was in the Summit Racing catalog, back when they used to sell them. On a Summit Racing crate 383 (still, bigger than the 350 it was designed for) it made 46 more hp than a TPI at 4500 RPM. It made more tq than the Super Ram, from the bottom of the dyno run (2000 RPM), up to about 4800 RPM and both had similar peak hp (on this 383).
What ever one's beliefs are about the effects of air flow inside the plenum, the thing works. It does what it was designed to do on a 350.
There is some FINE wording, in that there description!

I hate to see this turn into a T-ram vs super ram argument. IMO both are awesome intakes that are far superior to the TPI and both can make great HP with an engine setup to use them properly. I suspect the Super ram is meant to make power at a slightly higher RPM than the t-ram but the difference in power will likely be marginal.
Hi have to say Tom400CFI finding A t-ram is pretty amazing, they are so rare, opening the hood with one of those at any car show should draw in anyone in the know. Major retro neat factor! If I found a T-ram I would proabbly buy a third gen just to put it on.

I totally agree. Both amazing intakes, Super Ram is an awesome intake. Possibly one of the best for covering such a large range of applications/sizes and RPM range. I love the Super Ram also.
IMO the T RAM was likely a victim of timing. Looking at the layout it's possible a variable runner version could have been developed. The idea of a valve to switch from long to short in the main body. Unfortunately the passenger car days of the SBC were ending,
Great nostalgic find. Gotta love SLP’s involvement with F bodies in the 90s. American Muscle car series did an episode on the SLP cars that use to come on the Speed channel back in the day. It was a good watch.
