Picked this up from Summit Racing last week. It was a leftover unit from 1992. The manager I spoke to informed me that it was available for sale over the counter or through their catalog, but eventually was pulled from inventory to be used as a demonstration piece while training employees.

Its a little dusty...I haven't cleaned it yet. It is as you see it. All gaskets and bolts are included.















Plans are to clean it and display it in my garage

Wow.. Short runners on that thing, must have high RPM powerband.. How much did you get it for out of curiosity

Justin89Formy

iTrader: (26)

much less than it was advertised for

IMissMy86TA

is it for our cars? why not use it?

He's got an LS1.. This should be preserved as an historical monument lol

Justin89Formy

iTrader: (26)

yes its for a thirdgen. very limited numbers of this intake were made for the 1992 Firehawks. Since not all anticipated firehawks were made, the leftover performance parts were sold as gm performance parts, and through summit. this intake was leftover from summit.

I crossed my fingers and asked if he had any extra dana44 axles but he didn't

That's one cool display piece. Congrats on the find.

What's the balance line between the back of the side covers?

cs80camaro

Wow, that is pretty sweet

What is the hose for between the 2 side plenums? Some kind of balance setup?

The fuel crossover.
The fuel rails are cast in

Twin_Turbo

iTrader: (25)

That's not the fuel crossover. The crossover is between the 2 ports on the front or the 2 on the back. In some pics his has plugs in the front and rear and in others there are AN fittings.

Where was PCV on the t-ram?

TTOP350

iTrader: (8)

The line is for the fuel line crossover, it has just been misplaced by someone. There is also a metric ****ton of stuff missing from this manifold.


Justin, is this the one you just sold? or was it another one?

Twin_Turbo

iTrader: (25)

There is no fuel crossover, just a dual feed on the front, a plug on one side on the back and the pressure regulator on the ohter side. Optionally it will be possible to plumb the plugged side back to the regulator. The instructions also do not show this crossover line like that (not that it matters a whole lot, you can plumb these efi systems in many ways, flowing through both rails, regulated through both w/ a Y setup or on one, or even regulated before the rails with a high pressure dead headed set of rails)

Here are the 2 suggested setups per instructions:





Does it come with the thermostat housing and the funky throttle cable bracket/setup?

It looks like this:

Let me correct my statement, that line is part of the fuel line crossover used in the front or rear. It is not in its correct place.
People have manhandled this intake for years soo its missing parts, pieces and that could be something someone just made.

The side tanks have ports on the rear (which the fuel line "crossover/feed line" is incorrectly attatched) and bottoms for various systems on the car that need vacuum to operate.

Other than the t-stat neck, throttle bracket, cruise bracket, none of these SLP supplied parts are "correct" for a true firehawk anyway.

The cruise bracket was a option for the T-ram that have a auto trans and or cruise control. Only seen 2 Hawks with it, could be more but most cars had cruise delet.

This is prolly the T-ram I left my name on back in 2000 when I was at Summit and this was on display.

Why are they not correct for a true firehawk?

Leave it to Justin to have one of these deals just fall into his lap!

budfreak1

iTrader: (7)

Is this the one that was on the sales table, or did they have more of them?

TTOP350

iTrader: (8)

Firehawks used hard lines (SS) and there are 2 maybe 3 routings of them.
I have enuff pictures that I just about have the car numbers down to when which parts got switched.

Justin89Formy

iTrader: (26)

the first t-ram I had in my posession was plumbed incorrectly since the regulator was on the front.

doesnt bother me if it is missing small stuff. ..I never plan on using it

TTOP350

iTrader: (8)

Exactly, perfect display piece, unless you want to sell it 2 me

What size Injectors are in it?? I have a idea what the Hawks used but I'm not 100%.

I need that auto/cruise bracket and cables and the thermostat housing. The lines I can fabricate. I'm a serious buyer and can make it happen right now people...I know the T-Ram community is a tight group so lets see what we can find. PM me before I say screw it and sell my T-Ram system and just go LSx.

Twin_Turbo

iTrader: (25)

I'm not selling these parts. Took me a long time to find a complete one. Sorry

Justin89Formy

iTrader: (26)

damn dude you dont need to spsm every t ram post about. it


you should just go lsx anyway and make some real power

Not trying to be the T-Ram snob, but think it's worth mentioning for the betterment of the group. The cross over braided line is correct, just needs to be connected to the missing SLP regulator housing and the passengers side fuel rail. The fittings threaded in to the back end of the upper plenum were part of the fuel line adaptor kit. Most of the conspicuous hard to find parts have been mentioned except for one. The wiring harness extension for the MAP sensor.

These things are cool and it would make a great wall hanger in the garage as they were offered a GM option and via GMPP.

I always thought it would be cool to have one in a car that performs great. I bought mine because of an article in GMHT magazine from the early 90's. Guy had a white TA with a T-Ram on it running bottom 12's with a 350 and Trick Flow heads and the same cam I put in my car. My car never matched the performance so I don't know how accurate that article was. I still have the rag and have revisited it numerous times over the last 14 years.

BTW, those fuel line routing instructions look really familiar.

Twin_Turbo

iTrader: (25)

The line is correct as in, it's just a -6 braided line that you could use for the fuel plumbing...the way it's hooked up now is wrong.

Can you post the article? I'm going to build a new engine for my gray iroc using this intake, TFS G1 heads, a yet to be determined camshaft, Hedman hustler full length headers (the ones with the flat collector), new retrofit T45 etc.. etc.

The SLP regulator is nothing more than a modified GM regulator with one side capped off. I have a very similar one on my multiport (and the T ram with the one w/ the missing cap on it above is mine)

The runner length isn't as short as it appears. The radiused lower plenum runners extend into the upper plenum at the same radius. It's not easy to describe but the air flows from the TB down a central path in the upper plenum, then enters the side tanks from a centrally located opening between the intake runners of 3 & 5 ( drivers side)and 4 & 6 (passengers side). It then makes a 90 and moves to the ends of the side tanks and has to make another lateral 90 to enter each intake runner. From there the air has cascades down the radiused runner to each intake port in the head.

TTOP350

iTrader: (8)

That's what I was saying about the line.

Are you talking about the canted valve TFS heads? I have a set I bought new back in the day when they came out. I caught wind of a few issues with these heads. Really need a special intake rocker arm, the valve spring pockets squared up with the valve guide and a few others.

The SLP supplied regulator base is as you say, The real Hawks have their own special one , except a few of the last ones that used this one.


874ME,
How much longer is that MAT sensor harness than the factory F-body TPI one? I wonder if the vet harness is longer for some reason.
Please post the article when you can.

If you use the correct comp rockers there are no problems. They key is in setting the geometry right. I have these exact same heads on a couple of other cars. No one seems to like them but they make great streetable power. I have 4 sets of the G1s, only 1 set is toast. I got them used for cheap and the guides are all worn, the valves are worn on the stem and the face is brinelled, they used stock rocker arms and stock length pushrods. One day i will put new guides in them. They already have bronze guides (prev owner did that) and the crappy shot that did it must have messed things up because the guides are set in place w/ set screws LOL

TTOP350

iTrader: (8)

Yes, tfs said stock rockers would work, but they need special intake rockers.
I got the other info about the spring seat not being true with the guide/seat from speedtalk.
That makes the springs fail.
I like the heads, I need to put bigger intake valves in mine because I have the ports Opened waaaay up to a 1207 all the way thru, took like 1/4 or more off the port roofs.

I still have my instructions for my tfs heads.

Twin_Turbo

iTrader: (25)

The junk set I have I did some porting on as well. I removed the swirl vane and opened them up, there's quite a bit of material to work with. I will have to finish them and then drop them off for new seats and have the seat to guide angle checked. If the info is from speed talk, it's probably good info.

What engine combo do you have them on?

TTOP350

iTrader: (8)

I just bolted them on my stock shortblock 350.

This is back when they 1st came out, mid 90s?? went mid to low 12s then

iTrader: (4)

Now this makes sense to me.


Typo? Or custom input? Or?


Don't make threats. Get off your bum, pick up a "close enough" new water neck and have it cut & TIG welded (used ones are contaminated metal.) Then figure something out with the bracket. If your time and tools don't allow, put the work on someone elses plate local to you.

Twin_Turbo

iTrader: (25)

If I get my t ram off the container I can weld up a stat housing no prob.

As for the reply. It was an actual reply requesting said article for reasons outlined.

Any real performance gains with this intake? I remember back 14 years ago when I was starting out these things were for sale for the longest time at summit, seemed no one was interested in them at all and not much talk about it.

iTrader: (8)

One of the mags did a EFI shoot out years ago, It may be posted here or google may turn it up.

I think it was supposed to be 50 HP over the stock TPI.

Right. I was just trying to ask if you were doing a T45 behind a SBC.

The article on the GTA is still sitting in the magazine holder upstairs, Ill scan and post it Monday. You can see the harness extension in the photos I posted above, it's about 8" long.

The TF twisted wedge heads worked well with my ZZ4 shortblock and cam. The cam is the same as what was mentioned in the article. The problem with the twisted wedge heads was valve clearance verse piston. I used putty to make sure the clearances were OK before putting it together back in 2000. Wasn't aware of rocker arm issues. The heads require a custom pushrod length. The valve springs are crap out of the box and would venture to say the guides also. My car went from a tired TPI 305 to a ZZ4 shortblocked 350, T-Ram, TF heads and decent cam in one fell swoop. It made a ton more power and pulled really hard to 5800RPM. May car was on the road for about 10 minutes with the new engine and was prodded into to putting the hurt on a Roush S281 convertible. It got ugly for him around 30 MPH.

How many of you guys have put miles on your T-Ram? Mine has about 10K on it.

874ME

iTrader: (1)

Rereading this thread and noticed no mention of the fan belt protector or AC bracket either. I used the AC bracket as it spaced the power steering pump brackets correctly. Didn't need to use the fan belt protector as it's for the serpentine belt setup used on the 89 up? accessory drive.

You can see the top of the AC bracket in the 2nd pic I posted.

jmd

iTrader: (4)

I think that bracket is the one they also sold in an 82-87 F header-install kit years back. The rear leg is cut off and a new one with slotted bolt hole is welded on.

TTOP350

iTrader: (8)

Yes, that's correct, it's not really a T-ram part.

Twin_Turbo

iTrader: (25)

Just wanted to show off mine just got it in from the container shipper





needs some work to get it all pretty again..and then I will run it on my to be built engine in the 88 Iroc (gray one) witha retrofit T56 trans and a host of other stuff.

874ME

Nice find. That Cruise kick down bracket is not needed with a manual transmission....

TTOP350

iTrader: (8)

Unless he wants to use the cruise control.

Twin_Turbo

iTrader: (25)

I know it's not needed (and I refuse to run cruise with a manual trans) however I'm not parting with it. I like to keep it all together.

TTOP350

iTrader: (8)

Y not? People do it all the time, works just fine but it's your wheels and you may do what ya want.
If your not using cruise or auto in your build, you don't need the bracket, thow it in a box an put it on a shelf.
It's a part that wasn't really part of the T-ram until the Hawks were about done with production, not many (maybe 4?) got it.


And where is this article on the GTA??????
