I’m sorry the Speedmaster intake I ported was slightly better than the old style Torquer I ported. These three intakes were tested on a ported 2.02 valve set of Speedmaster heads.
I am very surprised at how close the M1 is to the victor! So, is the M1 that good, or is the victor not-very good?I am very surprised to see how little diff there is from the stock victor v/s the air gap all the way up to 600 lift.
I put alot of stock in a stock 340 with a tm5 and 700 dp running 13.1@104 winning bracket classes 10 or so times with the door stopdont put much stock in magazine add's....DWB!
Time and again, people will line up on here recommending the Air Gap over anything else. Nice comparisons, John. Thanks.Now let’s add the RPM Air Gap to this and this because again I’ve never used this intake I’m taking it is different than the RPM Performer?
-Head—M1 intake—-Vic340–RPM
.100—64——————62—68–66
.200—125—————125–131–131
.300—187—————183–192–188
.350—214—————213–218–211
.400—238—————236–237–227
.450—257—————246–251–241
.500—284—————255–259–250
.550—294—————256–260–254
.600—296—————258–262–251
.650—302—————271–272–254
.700—308—————279–280–250
As you can see the RPM Air Gap totally trashed a good flowing head causing it to get noisy, turbulent, then backing up. A dual plane was never made to work on a head flowing 308 but it shows you the importance of not just grabbing an intake off a flea market table and throwing it on your engine combo. Both of these heads the Victor340 will be tested again after some porting but will be tested hopefully on a different head. Hopefully have this pair of heads finished this week and gone.

Not to hi-jack John's thread here but just to show an amateur hack job, here's my Strip Dominator I did several years ago. It was a spur-of-the-moment idea, there was no plan behind it other than to gasket match the port openings. I never had it flowed so not sure if this did much of anything except create a bunch of aluminum dust. I only had short-shank burrs so I couldn't get far enough into the runner. Didn't really touch the plenum except for smoothing some casting flash on the entry. I liked doing this but after the third or fourth one it got really tedious.
Strip Dom is OK. The Victor has taller/straighter/longer runners if that means anything.

Dumore Grinder FTW. John, you turned me on to these types of grinders years ago, they're awesome. I think you have a Foredom? I need a foot pedal for it. The motor in mine is shorted internally, every time I turn it on it flips the breaker. Not sure what I did to it.

Sorry for the diversion, please carry on.
Years ago I ran a stock stroke 340, 11.4-1, Edelbrock's that flowed in the mid 290's, 236/242° @ .050" hydraulic and a Weiand X-cellerator. For that engine the Weiand was a good fit. An Air Gap would be better for something with less head, cam, compression and gear. If I was running 3.55 gears I'd run the Air Gap, with 3.91's a smaller single plane like the X-cellerator would be tempting.So at what point do you make the call to go from the air gap to a single plane for a mostly street driven engine?
Lets say eddy heads/or eq heads that flow about 260 @.600 are on the hypothetical engine. 340 or 360 engine.
John said “Old Style Torquer.” Not Torker II 340. That’s how I read/understand it.If that’s the X-style Torker 340, it’s surprising to see it flowing that well after porting. Did you happen to see what the ports with the pinch for the bolt flowed?
The “Torquer” tested was the “Torquer II 340” and not the older Torquer.[/URL]
the torker beat the strip dom 475@6300
made more torque then the airgap starting@4800
nice door stop
Can’t wait for those babies! Should work well with my rpm air gapMy next set of Speedmaster heads will be interesting. I haven’t done a full port job on a set of heads with a stock 2.02 valve in a long time. Being the throat is already at its max from the factory I will be limited to setting my own angles by hand instead of using my seat cutter. That would probably be a perfect fit for this ported RPM intake especially on the street.
Boy, that thing has led a hard life.....

Cam size/specs/duration @050?I updated that post mentioning one person in particular with a 340 that went faster with a single plane to an air gap. 11:1+ with 4.30s and a four speed in a Duster.
Sorry, but please prove this to me.dont put much stock in magazine add's....DWB!
PBR has a Torker. The intake in the article is a Torker 2. Not at all similar.[/URL]

almoxt exactly the same the torker2 has the turn in a different location the torker 2 was suppose to have better low speed torque the tm5 is probably the best of the 3PBR has a Torker. The intake in the article is a Torker 2. Not at all similar.
