Thermoquad on RPM Air Gap

Thermoquad on RPM Air Gap - 10/17/10 11:19 PM

With welding and grinding do you guys think I can run a Thermoquad on an Air Gap intake?
Would it work well even if I got it to fit?
Should I?
I am having a hell of a time finding an LD340 to use so I thought if I did some work to an air gap it might work.
The more I type the less this makes sence.
Any input?

i looked at my ld340 and there isn't much room there also, it looks like if you open it to the good gasket or plastic spacer there would only be about .030 on the secondary side unless you weld. NE1 have a pic of a LD340 opened up to T-quad size.

You would have the same problem with and LD340. They are not set up for a thermoquad either.
yes it will work with a little grinding but why not just get an adapter.

I don't have a picture, but I hogged my LD340 out a few years back and there is plenty of room left after doing it and I'm using the big bore TQ with no issues at all.

On a non shaker Ebody, there isn't a lot of room under the hood for a LD340, TQ and adapter plate.

Re: Thermoquad on RPM Air Gap - 10/17/10 11:31 PM

The LD340, like the CH4B big block intake, was designed with being able to go spreadbore in mind. You can see they put extra meat in this area just for that reason. Why run a performance robbing adapter when the intake can be hogged out to fit? Keep your eyes open, a reasonably priced LD340 will pop up.

I foolishly had that same combination for a litte (Thermobog on an RPM air gap). Just use an adapter... or better yet use a real carb.

Re: Thermoquad on RPM Air Gap - 10/18/10 01:56 AM

The LD340 works great with a thermoquad, I have done it before to a couple others and love it along with the owner of one I did it for.
I have been looking through the classifieds for a while and have not gotten much luck.

A properly tweaked THERMOquad does NOT have a BOG issue at all ...PEPSIkid

And an ADAPTER is fine on a truck or RV ... but anything HP .. those adapters are NOT the plan.

Can the Weiand Stealth's be hogged out for a TQ.

The picture would appear so, but I haven't tried one.

Was thinking of getting one for my LRT.

Say what you want, there's a reason OTHER carter designs like the AFB is still being produced and thermobogs aren't.

The REASON is ... is those AFB designs are simple UNefficent carbs that are EZ to produce ...... compared to the TQ.

And this stupid thermobog title ? ... if you TWEAK the carb right(with the proper tool ) ....

The CORRECT title would be thermoKICK .... as the secondaries come-in and SPIN the tires !

I believe that the Mighty Three have spoken the truth!! Daytona has proved that if you can SEE the mounting for a TQ, it can be mounted WITHOUT an adapter, Doc has proved that the TQ is NOT little as you say, but being a very FLEXIBLE carburetor (fits on any Mopar v-8 regardless of displacement). Scott proved that it doesn't suffer
as much from mixture problems as the "other" carb which you call "real". No problems here at ALL with YOU using a REAL carb!! Just food for
.

Doc, lighten up on the AFB's. They were designed
differently from the TQ's in terms of power. They
seem to work better in multiples, rather than singles (hint HEMIS, M-W's). They apply power in a slightly different flow pattern to the motor. All in all, a VERY good carb, and IT HAS IT'S PLACE!!

Re: Thermoquad on RPM Air Gap - 10/18/10 04:53 AM

If you look at both carb flanges on the LD340 and the Weiand 8022 you will notice that there is 'extra' material down both sides front to rear for the big 2ndaries of a T.Q. or other spread-bore carbs. This is purposefully done.

So the way to mount a T.Q. on either intake would be to take a T.Q. specific mount gasket and trace the pattern to the inside of the gasket on the intake itself and grind/shape as needed.

Or use a spread bore to square bore adapter. I have found that you will need to use a T.Q. mount gasket as a pattern and also grind the spread bore side to 'match' the 850 cfm's larger primaries to the front and outside edges for proper flow and to get rid of flow restriction.
If this is not done, the 850 cfm will perform poorly. If the work is done, the adapter works great, David.

Re: Thermoquad on RPM Air Gap - 10/18/10 04:23 PM

Why do you guys assume an adapter is robbing HP? Many Many guys find they go faster with a spacre and an adapter is almost the very same thing. Mabey I am the only one who does this but I like to take the adapter, bolt it on the intake and port it to smooth the transition till it is like one single piece of aluminum, thats how I roll with them on intakes not desighned for them and they seem to work VERY good. If you do that there is just no where for the HP to disapear

Not all M1s BTW can have a t-quad bolted right on and since he is talking about air-gaps and LD340 intakes it sounds like he wants a dual plane and the t-quad will not bolt to a M1 dual plane, onlyt the M1 single plane.

Thanks Dave for the clarification on the spacers and adapters. I with ya, they don't
rob power but fine tune the airflow for the power
to work best in certain ranges.

Re: Thermoquad on RPM Air Gap - 10/19/10 03:27 AM

IIRC a few years back one of the mopar mags did a dyno test on those adapters and showed them to lose HP. However if they would have done like you describe, bolting them on then smoothing out the transition I suspect the loss would have vanished.

Why I ask is because the Thermoquad/LD340 combo works fantastic for me and what I use it for.
But since I am having a hard time finding an LD340 and that the RPM Air Gap is a great intake along the lines of the LD, I thought it would be great to combine a Thermoquad and RPM Air Gap.
Thats what/why I am asking.

Short answer, absalutely yes, great combo! Long answer....It depends on your engine combo, but still likely a good combo for most any a street car.

I would be tempted to try out one of the spreadbore holley double pumpers on it. I think that could also make for a nice combo on a street car.

It bolts to the adapter not your intake. Just saying if he wants to do it with out an adapter the m1 dual plane is out, I would do it in a heart beat.

Re: Thermoquad on RPM Air Gap - 10/23/10 04:22 PM

I would like to know how they conducted a test like that, if you swapped carbs to keep the flow going the way it was intended you could get differend results because the carbs were not on par, if you used the same carb for both tests you would have huge steps in the transition on one that would ruin that test

Original poster. Street car right? Why not just run a stock 71-78 cast iron intake? Heck probably get one for free if you bug enough buddies for what they got laying around. Worst case scenario maybe twenty bucks.

Thats a 79 but I wish it was a 78 because of that stupid tin thermostat housing they started using and turned 45 degrees starting in 79. I missed that completely until after I sand blasted and painted it.

Not a bad idea, i dont think you would be giving up to much HP with a 71/72 intake, especially if modified and port matched but they are heavy !!!!

Re: Thermoquad on RPM Air Gap - 10/28/10 09:15 AM

Yep, my TQ on a 318 stroker bogs all the way to 12.6 - and thats a NON reco carb, with 40 year old floats and bowl - and there's more in it.

On topic - I have hogged out both an LD4B and an LD340 successfully - an air gap should prove no issue either.

(PS - Don't listen to what some "others" on other sites have to say on this issue - they're yet to prove to be able to run a qtr time, let alone know what can and can't be done with a TQ and a 4B or LD........listrn to the Demon .)

Re: Thermoquad on RPM Air Gap - 10/28/10 11:17 AM

Is there a provision on the LD340 and the Air Gap for the automatic choke? Or do you use a manual choke. I've noticed this on my LD340 intake and have thought about using a TQ that I have.

If you feel comfortable "reworking" the Air Gap
go for it! The performance loss would be minimal if the "machining process" is done right
and the bores are blended smooth! LD 340 would be a little better to do, but the Air Gap manifold is the next best thing! You're on track my friend,
take your time and do it carefully!!

Re: Thermoquad on RPM Air Gap - 10/29/10 04:16 PM

I think some of you guys have never had a t-quad base plate sitting on an RPM or RPM air-gap, there just is not enough meat there to grind away, you have to weld up the flange area then mill it back flat then you can grind clearance for the blades and have a smooth transition. That is the only way it is gonna happen unless you run a thick gasket and only grind minimal clearance for the opening blade and in that case you have a big step that will hurt performance, possibly cause tuning issues and fuel seperation. You wil still be asking for vaccume leaks because there is only about 1/32 gasket clamping area if that(may vary a few thou either way depending on particular castings). I tried everything I could imagine to do it and ended up with a mr gasket adapter siliconed to the manifold and a thin gasket, an air cleaner fit just fine with a drop base in my 68 cuda, I would have guessed an e-body would have had a little more room but I really don't know about e-bodys.

Re: Thermoquad on RPM Air Gap - 10/29/10 05:15 PM

I have modified LD340 intakes for thermoquad use. They can be done nicely. It really helps to be skilled with a die grinder and it takes more time than most think. I've looked at perf RPM intakes with the intent of modifying for a thermoquad and concluded it could not be done without adding an adapter (to an already tall intake) or extensive welding.

Note: No aftermarket intakes that I have measured have as low a profile as an LD340. Going from memory, they are about 5/8-3/4 inch shorter than a perf rpm or weiand action.

Re: Thermoquad on RPM Air Gap - 10/29/10 07:58 PM

I scribed out the carb gasket on the LD i have and the secondary side would only have about .060 on one side to seal, other side is better at .100, is this ok Rapid??? its awful close unless i want to leave a step.
Posted By: Rapid340

Re: Thermoquad on RPM Air Gap - 10/29/10 08:14 PM

Sounds a little thin. Look at the gasket up against the carb, if it is much bigger than the bore openings look for a different gasket. If you are using one of the phenolic spacer gaskets, they tend to be large. I would make an effort to limit the opening in the manifold to a size no larger than the carb would require if it were sitting on the manifold without a gasket.

Re: Thermoquad on RPM Air Gap - 10/30/10 12:43 AM

HOt Rod Dave - I'll put my hand up and say I've never seen it done with an RPM / Air Gap.

Looking at this pic of a 340 - there's obviously more "meat" in the back half of the flange, making it possible.



I did think the RPM was a very similar design to the LD series - so its interesting to find that the flange is significantly thinner.

Silicone is bad for intake to carb surfaces. Could you have tried J-B Weld on it and work an adapter? Silicone is TOO messy and disrupts the flow from the carb through the intake and to the heads! Food for thought!!

I just siliconed the spacer to the intake, then blended it in with the die grinder so no left overs hangin in the plenum.

I have done an LD4b and it has a different carb pad than an RPM, the LD4b and LD340 have basically tha same carb pad. It only took a couple minutes to rough it in. I used an 850 t-quad baseplate and a black marker to mark color everything in ther to remove, then I mounted a christmas tree carbide in a router and ran it around to remove all the black marker then hand blended the transition with a die grinder, almost looked like a cnc had done it when I was done.

I used a 850cfm TQ and adaptor on my Performer RPM manifold and it worked great on my previous Duster. Much better all around performance than the squarebore Carter AFB 625 I was running. The top end power was soooo much better. With the adaptor and thick gaskets I cut a hole in the hood for the scoop so I could run a taller air cleaner.

Thanks all for the thoughts, I was originally asking about the Airgap because i was having a hard time finding an LD340 to use with the Thermoquad.
I have found the LD340 I was after and all will be right with the world and my Thermoquad.
Mostly I was checking to see if any one had ever done the welding to an Airgap and had a Thermoquad bolted up.
Thanks again.
