Hi everybody,
My question is about the intakes for TPI cars. Does anyone make a Carb type manifold with some kind of adapter to use a throttle body & the 8 injectors with a fuel rail already installed? The reason that Im asking is because the Miniram/Superam set ups are way overpriced! I need a combo that allows the motor to rev to at least 6500rpm with ease.

Port and Siamese your base and plenum and get SLP runners and do the same, that should let it rev higher. but if that doesn't work and MR/SR are over priced you might be looking at a carb.

Accel makes an intake called the Pro-Ram that is excatly what you are talking about, it's a single plane intake that has been fitted w/ injector bungs. For a TB you have serveral options. The cheapest would be to take a 454TBI unit and gut it of everything except the TPS and IAC . Bam, instant throttle body w/ IAC and TPS for your computer. You can also buy elbows that are made to mount GM or ford TBs to the carb flange. Or you can buy a high dollar fancy billet carb baseplate style TB.
You also don't have to buy the pro-ram, you can convert any single plane intake to FI just by welding/drilling the injecor bungs and fuel rail mounts. Even getting one custom done will be significantly cheaper than buying a MR/SR.
As for a comparison, our own guido is currently running a MR, but he's thinking of changing to a single plane style. Look for some back to back runs (the beauty of the MR, you can swap intakes at the track, in a reasonable amount of time, try that w/ a SR, lol) next year to see which truly is the best.

I have a cost efficient alternative to the Miniram. Just swap that old non-breathing and heavy TPI intake for a factory LT1 intake. The LT1 weighs half of the TPI BTW.

You say it's impossible? Won't bolt up? Well your right but ANYTHING is possible when cost is a factor. Here's some of the biggest issues you're going to run into and a quick explanation of what to do about it. Look for a tech artical soon.

There are several problems with the STOCK LT1
intake but the ports and coolant passages are not one of them. What I did
before I started was get a cheap $6 intake gasket from DAP and just layed it
on the intake (already off the car), everything was perfect except for some
of the mounting holes, the 4 corner ones were good. No problem, I took the
gasket as a templet and drilled the new holes in the intake, no more
problem.

Problem #2, in case you havn't noticed there's no rear distributer on a LT1.
I had to drill the hole for it, warning-this hole must be in perfect
location. I used a old TPI base and made an aluminum templet utilizing the
rear two mounting holes to locate the dist hole. Distributer must be shimmed
about 1/4" higher due to the shortness of the LT1 intake. Also must use the
small HEI distributer with remote coil found on 1987-later.

Problem #3, No front coolant passages to return to the radiator. Well, I
just drilled and tapped two 3/4" heater nipples vertically where the coolant
would normally exit the head. I will run 3/4" heater hose to a remote
thermastst housing I found on-line. it will be mounted on the fenderwell. It
will use the same outlet neck and return to the radiator as it should.

Problem #4, must have custom fuel lines made to attach to the fuel rail of
the LT1. About $40 if you supply the ends. Available from Pep Boys.

Wow John, great work. What did you do for a dist. hold down bolt? I guess the easy way would be to drill/tap a hole in the intake and use washers as a base to get the height of that set right?
If that really works (and i see no reason it wouldnj't sinc ethe ports line up), then the only tricky part to stop anyone from doing this would be the dist. mounting issue. If you could mock up an easy to use jig/template i'm sure a lot of people would use it, and could even make you a few bucks for your idea.
...ed

 

so there is a coolant passage on the LT1 intake, just not a return to the radiator?

 

No, there is no coolant passage in the intake. The coolant normally enters the intake from the first port on the head forward. The intake is blocked off. I drilled and tapped for a vertical heater fitting on each side and will run the 3/4" heater hose to a remote thermostat housing then to the radiator. You can see one fitting in the pic above drivers side forward. Here's a pic of the housing.

Not that the miniram has one, but I assume the stock LT1 EGR has to disappear for this to work.

 

...And,

 

Holley does. $255 for the bare intake from summit. 4x cheaper than TPIS!!!

There is even a Vortec version for about $435, almost the same price as a Ram Jet bare intake.

John you should seriously make a tech article with all that stuff and pictures etc.... thats really cool, id really consider doing that if you made a good tech article with pictures.

 

Absolutely the EGR must disappear. Due to the distributer. Now if you went distributerless ignition well........

I wonder if one of those offset distributors I have seen would clear everything.

 

i was thinking about making an aluminum box out of some sheet metal, and cutting the runners in half and rewelding the bolting part of the runners to make my own home made super ram.

 

can anyone with a super ram go out and take some measurements of the box for me?

 

Thats how it was originally designed.

 

There are also distributorless ignition systems. One company is Electromotive.

 

Here's their website. VERY EXPENSIVE.

John that is awesome. everyone said it cant be done or would be a waste of $ and time.


Im in the process of tryin to make a polly or carbonfiber SuperRam (runners and box). I have all the suplies at work.( the ability to make a mold, etc.)

My biggest problems are
What to do about all the bolt holes. i could sleeve em like the LS1 maybe.

anyways, GREAT JOB. keep everyone posted how it works.

 

I am very interested in hwo your home made intake is going. You get this thing to run right, you better get the rights to it. The sheet metal would be so cheap you could dominate the market.

 

VERY NICE. Very, very nice work John.

Looks like someone's gonna put TPiS outta buisiness...hehehe

Damn, I know where I can get an LT1 intake setup too...use the LT1 injectors and put it on top of a 327 or an L98 with a 52mm TB and let it rock...oh yeah, baby, oh yeah. 400? We'll save the SR for that.

Wonder what that would do for a 305 with Vortec heads and a ZZ4 or LT1 cam?

I gotta try that when I find another LT1 intake base...now maybe he'll find a way to make LT1 heads for L98's Looks like you proved everyone wrong, good job!

 

ttt

 

dhirocz, you can put LT1 heads on a L98. There is a tech article on my website. Its not worth paying someone to do though.

I looked into this and even with my machine shop connections it would be about $1000 to have it fabbed up to work. You can't just build a box, you must radius the inlets and do some interior resonance work. If it's just a shoebox with holes you'll go nowhere fast.

 

Damn, that's pretty cool. First I see a post on how to put an LT1 intake on a standard SBC, then LT1 heads onto a SBC. Anyone do both? If that's all that's required, hell, I had an LT1 longblock I just got rid of (damn) but I'm gonna buy a '84 S-15 for a daily driver, clean truck...when the Camaro get's running I'm gonna drop a low-buck TPI setup into it, I have everything to build a shortblock or Vortec longblock, I'll have to look into this...thanks man

The nice thing about it is I have all the resources to do that work myself...just plug two holes, fix up the coolant passages to the intake and drill a hole for the distributor. I wouldn't even have to mess with bolt hole angles. Then fab in a thermostat adapter and were ready to rock...

Custom EFI Intake Setup

 

It looks like a low cost/high performance alternative has been found. You can either use an LT1 intake with the mods John has done or the Holley intake with a gutted 454 TBI. The only snag I have is getting a computer & harness to run the setup properly (my car currently has an RPM intake/Road Demon Carb). I don't have the required eprom burning knowledge or tools . . . yet.

This is very good progress.

Nice...how's it run? Keep us posted

 

Good job man. You have figured out a very cost effective alternative to a miniram

If I ever swap to TPI I'm definately gonna use a LT1 intake.

 

When U performed the modification on the manifold would u say that it was pretty easy, medium or hard & if I were to send u a manifold how much would u charge to do it up

anymore questions class?

 

thats happy nice

 

John,
I love the idea of adapting the LT1 intake but the EGR is a must in my state. I kind of wonder if it could be adapted. I guess with a little engineering it could possibly be done, although you have already done a lot with this system. I think this is what hot rodding is all about. Evaluate, Adapt, and Overcome.

 

It would require a lot of thinking and design but yes, I'd say it might be possible to use some type of REMOTE EGR on the conversion.

 

Theres the new Holley Stealth Ram manifold.Do a search to find pictures,or go to Holleys website and look under "whats new".The local Holley dist. here told me $265 for the manifold and $155 for the fuel rail.He was told by Holley it would take about 3 weeks to get it
