TQ DIFFERENCES

-
Push in jets are not soo bad...can drill them, solder them yadda yadda...not a deal breaker for me
 
The push in [ PI ] jets never caused me any problems. My understanding is that the PI jets could fall out, hence the update to SI jets.
With my PI jets, I got some thin springs that gripped the side of the jets & extended to the float bowl floor & kept the jets in place.

Jets fell due to rubber o rings that crumbled with modern fuels. Use viton or similar materials and motor on.
 
Rumble,
I do have an article on a 1970 455 Buick that ended up with a 1000 cfm TQ. Started off showroom cond, 3.64 gears & ran 13.9 @ 100 mph. Various stages of hop up, then Edel intake & modified QJ, 11.85@ 114.5. TQ next, 11.6 @ 117. Says' TQ has proven excellent for racing'.
 
Cool! I have not ran one at the track. Just swapped them out. Always a gain. Mileage and WOT throttle. I’m looking forward to getting my 1,000 on the track.

We had a member here (whom passed away a while back) claiming to have knowledge of there actual flow rate which he stated as 915 cfm. Not to damn shabby. Ought to catch a few with there pants down… LOL

Gotta love “That Sound!”

The rating was different from holley due to the water column used.
A 1000 flowed = 950 holley, remove choke and co tour the airhorn, dress the blade screws and shaft for more flow...over 1000 cfm.
Further, on open plenum intakes, use a 1" spacer and remove the carb's secondary baffle plate.....if track and stall convertered. I hear it picks up a tenth or 2

Oh! You mean like this then…..

:lol:


IIRC, *I Think* that spacer is from TransDapt or Mr. Gasket. I forget. FWIW, between the spacer and the intake, it’s going to need a die grinder!

I’ve heard a 50/50 on the baffle plate. On day I’ll test it out. But I won’t grind on this carb. I have a few other TQ’s I butcher up for curiosity purposes and will modify one of those instead. It’ll probably look like a troll and a witch had a child, but I’ll see how it performs.

Adapter, yes, but not a spread to sq bore piece...you could grind out 1 to port match spreadbore intake, and enlarge the squirter nozzle 2-3 thou.
Leave the choke platr snd shaft off...=@ 50 cfm
 
That spacer above is TQ shaped.
The spacer is 1.00 inches thick.
Plenty of grinding can be done here.

So far, with few exceptions, no need for a choke in this part of Florida. During the winter, (be prepared…) we had one night of SHOCKINGLY cold weather, (LMAO!) it went down to a low of 28*F!

:rofl:

I will say this though, the cold here is different than in New York. I’ve been out in minus 28*F before, just as a point of reference. I didn’t like that night here in Fl.
No sir!

Removing the sec baffle might well pick up a tenth or two. I have an original test of the Comp Series TQ from 1970. Photo of the TQ on a box intake on a 426 Hemi; caption states HP jumped by 30 when sec baffle was removed.

So what exactly is the purpose of that baffle? A 30 hp gain is a big increase in air flow. Or something.
 
Air flow direction is what I see with the baffle.
I don’t understand how a less than .060 flat steel plate increases that much power or air flow.

(I also stink at dyno guessing.)

I love TQ's! Wish the RPM Airgap came prepped for a spreadbore. I have no hood clearance for an adapter.
 
That would be really sweet. I’ve asked Edelbrock about this and they always say…. Time and time again….

We never get that request.


Bull ****!!!

The Weiand Stealth ported rod the TQ will do excellent.
 
Rat,
I thought the claimed HP benefit from the baffle removal was excessive but that is what is claimed for the test.....Anything is possible I guess.

I'm running a BPE 408 so the RPM Airgap is a bit special with the use of the magnum style attaching bolts. Can't just swap manifolds, unfortunately.
