I would guess that you will be using the high beam pockets for cold air intake?




That has been considered. Not totally sure yet.

Intercooler?




I wonder how much those long rams will act as an intercooler?

And what is the tuning effect of adding additional psi to those long rams, does it move rpm peak tq up or down?




I dont think the long ram length will help at all
for any cooling... if anything they will hold heat..
E-85 would help cool them SOME

HOW long did it take to polish those pipes?! No other brand has cool like that.

The longrams moved the torque peak down NA so it should just be more torque in about the same range. Let's see 900 ft/lbs @ 2500 rpm...

Love the build and every aspect of your direction, very cool car! The twin turbo Long Ram will be a torque behemoth!

Have you considered reworking the plenum dividers to bring the torque curve higher like a short ram intake? I have a diagram to show how it's done, pretty easy mod

My reasoning was since the intake air is now pressurized, ie denser, the ram sonic tuning should change, but by how much and which way, I don't know.


Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.

i'd like to see that diagram.

we really haven't been worried about the torque being too low. in fact, we are hoping that it will be a low rpm torque monster... i've split my fair share of blocks over the years and am hoping with this project to not spin it to the moon and maybe save on parts. it's a stock block with program caps, eagle rods & crank, indy-1 heads(left over from the candy wagon) small solid cam, and small turbos. this without a doubt isn't the all out race effort/most efficient/maximum power/set the world on fire combo! the car might still be heavy, and i'm not gonna set any records. we are really building this to look unique, run respectable, hopefully not break parts, and be able to nuke the tires off at ANY speed!

Just wondering are you going to add EFI to the long ram manifold??? Great build, I like someone who thinks outside the box!!!

I love it....but it is begging for port injection and dry throttle bodies so ALL the compressed cross section through the manifolds is AIR and not displaced by solid fuel which robs volume for the air to go.

Also with those isolated bank runners a 180 degree (super light and super strong) Crank would be INSANE with all that available manifold torque.

In theory you'll likely need some of the ram effect to provide torque before the turbos kick in if going with blow through carbs as they will work like a NA setup until boost kicks in. The "Short Ram" modified intakes should provide plenty and offer a happy medium by bringing up the torque peak 1K rpm or so.

Here you go

1. Center Punch & Drill two holes through the flat surface of each manifold 10.50" from the cylinder head end of the manifold tubes in figure A. Now center punch & drill two more holes as close to the carburetors as drilling and sawing will permit.

2. Saw completely through manifold along the dotted lines in figure A. remove cut out section figure B.

3. Remove inner wall of this section leaving only the top and bottom plates intact.

4. Carefully remove remaining section of inner wall below carburetor flange of manifold figure C.

5. Round leading edge of remaining inner wall to .125" radius figure D.

6. Reassemble upper & Lower surfaces of cut out sections by welding.

7. Leak test manifold assembly w/10-15lbs of air pressure

8. Re-machine all gasket surfaces to remove any warpage from welding heat.

Well I like the long cross rams, I would do it a bit differently...I would look to do somthing more performanced based.

thanks for the diagram! but i've got WAY too much time polishing the intakes and won't be cutting them apart!

i'm sure it will be a slight learning curve, but i also think sometimes we tend to overthink things too. back in the early 60's these long rams were used with some success, and i believe set a few records on a bonnevile set-up that used blowers.it might not be comparing apples to apples... i have thought about maybe adding a small shot of nitrous if it's a slouch off idle/ the line. who knows... only time will tell

The cutting can be from the bottom side so it won't show. You are basically just removing the bottom side of the tubes, grinding away about half the divider wall along it's length, then welding the bottom back into place, piece of cake~

As long as there has been some interest in this project, why not have some thoughts on what sort of power/ torque this thing might make ...I realize it's a shot in the dark to some extent because of the wildcard intake setup, and they might leave 100hp on the table but I'm curious to see what the general consensus might be.... Then look back when I dyno it and compare numbers
Here's the basic specs

440 Blk. Program caps
Eagle rods 6.76
Eagle crank 4,15
Ross custom dished pistons approx 9-1
Indy 440-1 heads decent flow #s but I can't find the flow sheets. They do have the 2.25 valves though

Cam Solid Flat Tappet
.576 lift
274 adv dur
[Email]246@.050[/Email]
114 lsa

Turbos Borg Warner
S400-64mm compressor
83 x 74, 1.10 A/R T6 Turbine

Carbs are Holley 450's set up for blowthru

We will probably try to figure out tunes for race gas(110) and one for pump gas (91) as well

So....... What do you all think??

Someone did a lot of work to mod those intakes, if it's not a 'shop.

WAG?

I had a rebuilt, mostly stock, 1960 Long Ram engine. Stock stroke, bored to 426 cubes, forged 9.6:1 lightweight Diamond pistons, stock rods, stock heads with bigger valves and a mild pocket port cleanup (these heads were quite restrictive, I'd guess at only around 220-230 on the intake side) stock 2903 afb carbs (they flow in the 400-450 cfm range) a hydraulic Comp XFI roller cam, lobes have between 236 duration @.050 up to 242 @ .050 with .630 lift at the retainers with 1.5 ratio rockers or .672 with 1.6 rockers, lobe center is 111. with this cam the party is over under 5,500 rpm. We dyno'd the engine and it made 512TQ/405HP with stock exhaust manifolds. Peak torque was around 3600RPM, peak HP was a around 5,000rpm, timing set at 34 timing/74 secondary.

With that in hand;

Your combo would likely yield similar numbers but with the 4.15 crank you'd likely hit your peak torque at a lower rpm and probably 25-50HP due to the better heads. I'd guess with the blow through turbos you'll be gaining between 150-200HP. I'd recommend having your pistons and other combustion chamber parts high temp coated and a water or methanol injection setup to keep things cool in there.

Take a look at my dyno sheet. This is a 470" engine with an unported weiand tunnelram on a set of 906 heads. Running 14psi with twin te44s on regular old pump gas and no intercooler.
This is chassis dyno, so the converter does play a part, but this is what the tires are seeing.
