very involved question

[Big Mudder]

I heard about a small block chevy build on the site before 406 sbc I think it was running both a dual tunnel ram and a procharger, I was wondering if running a roots type or twin screw supercharger with a dual tunnel ram would be possible and if it is what kind of work would it take to actually get it to run on a motor and not kill it?

I want to make my camaro one of the fastest street legal cars in the country and stick with a 350 just to say I did it with an ls1.

[Jthomas]

My old man did the dual ram with roots, pretty simple. You just make an adapter to fit the ram with the blower bolt pattern, and put carb spacers or injector spacers under the adapter.

Here's a plate I made to adapt my large opening manifold to a standard opening blower



But I think there are really only a couple blower guys on this site including me.

[Jthomas]

So you would have to weld the spacers to the opening on the plate, then it will bolt right to the dual ram.

Maybe do it with a 471 roots on a small block 350? Or f it and go bigger. I'm just not sure how goofy it will look with anything bigger?

[Big Mudder]

I was thinking maybe 671, don't want something too big but not too small either.

[Jthomas]

Weld this to the opening of the plate. Then it will bolt right to the top of the intake.



Bam, then ur done

Btw, 471s are sick.

[Big Mudder]

I am gonna need help with it lol, I have never welded or even bolted on a supercharger.

Edit: Ok so I just came across a thread on 3rdgen.org of a 471 while I was looking them up and guy had setup one with an innercooler idk if he meant intercooler or not but he said he built it for a nitrous blowoff but it ended up cooling the engine and he said that it would add 100hp on its own, my secondary question is if I ended up going with the 471 and dual tunnel ram together would it be possible to mount the intercooler to the plate on top of the tunnel ram and bottom of the blower for more power or would it just be a visual piece?

[Jthomas]

A chiller (intercooler) is like 3" thick. And useless on a car. A chiller works like a radiator, you can't cool boost with 200*F water. Thy only work on boats. Just forget the inter cooler. The example I showed u was the best and easiest way.  Btw, this blower will sit very high.

[Jthomas]

Best way to make a plate, trace the base gasket on the aluminum plate. Cut it out. Set the blower on top, punch the holes, then drill.

Make sure u use aluminum bolts on all aluminum pieces, cuz good luck getting steel ones out. But you won't be able to use blower studs, unless you used really thick plate. $$$ so you will have to bolt it, torque the blower to 17ftlbs. I've herd 15-20 ftlbs

Once u weld ur plate to the spAcer, it's just a matter of bolting the spacer (which is now welded to the pate) to ur intake, then bolt the blower to ur plate.

Look like this.

3rdgen.org is the number 1 website for 82-92 camaro's and firebirds so he mounted it on a camaro or firebird.  But either way whether the intercooler was used or not dtr and a roots type supercharger should make north of 1000hp on a 350 shouldn't it?

[Jthomas]

Not even close.

I have a big inch motor on a 671 5psi. On pump gas I'll have like 850+hp

U won't go over 650. Guarantee it. Unless u ran race fuel, high boost, and put big $ in.

But im tellin ya, don't get the chiller, it will be a waste of money for you, u get like 100hp with one, but u can't cool boost with 200*f water. U just can't, it won't work, and if anything, warm ur boost. They only work properly on boats.

[Jthomas]

Not to mention, if u use a 471, it wont have the flow of the cfm's of a larger blower. U would atleast need a 871 or larger. You would have to run injection. Blown injected is IMPOSSIBLE to drive on the street. Trust me, you would be VERY unhappy with it. It would have shitt MPGs, track use only. Then once u put enough boost on it, it would suck more fuel. U would have to run like 117octane, retard ur timing out the ass, which u would burn ur exhaust vales and hope u don't detonate.

But it's possible and $$

If you ran alky on the otherhand...? You wouldn't have to worry bout detonation. Run crazy boost and crazy comp ratio and keep goin.

well, I am thinking about making my own ethanol to run the car, my cousins know how to make moonshine and I know making ethanol is just processing moonshine a little further to be able to run it.

We made some, you have to get a license. (we never got it tho) It's alot of work for not very much at all. And if your running ethanol, you burn X2 as much as gas. So I guess there is a trade off.   Just keep the moonshine flowin

am i missing something here? why not just buy a blower kit for it? they sell the complete kits in jegs with manifold and everything......

x2.. and you mentioned a 406 a 350 and an ls.... so which are you gonna be working on??

Becouse then it wouldnt be " A Very involved question" thread ....LOL

it would be a blower with a dual tunnel ram, it would be something different, everybody and their cousin has done a blower build and same with a dual tunnel ram, you almost never see a car that has both a blower and dual tunnel ram on the same engine, even if the hp gain is marginal over each piece by itself it is still cool looking.

You can look at it like turbo vs supercharger, turbo will almost always make more power than a supercharger but you go with the supercharger just so you can have that scoop sticking out of the hood and any would be street racer will be able to look and say. "Ok don't want to challenge him."

is that a money back guarantee???

[Jthomas]

I said it was possible lol. I see small block 454s with 1000hp. But I'm guessing he isn't gunna spend as much, I'm saying for his build he won't go over 1000hp. Guarantee it. Loll
