Edelbrock Air Gap Dyno

[msdnga]

Well, I tested the new manifold using all the Hughes  supplied parts. I removed my 2bbl M1 and 55TB, ran the new setup and gained......



nothing.

Still 341hp and 383 ft lbs. I am sure with a bigger cam, it will shine.
Test was done on a 408 10.3 comp, R/T heads ported, 210/220 108 cam, Pacesetters.

Again, nothing....sad day on the dyno.

Before I put my engine together I thought about the concept of the airgap manifold.  It remiinds me of the old school dual plane manifold and the M1 reminds me of the old school torker.  With a bigger cam, wouldn't you still be better off with the M1?

[msdnga]

I was hoping the TQ would have hit 400, but nothing. I'll try putting a 4bbl Comp TB on it next before doing a camshaft and redyno.

marty what do you think of the hughes 2228 cam

[msdnga]

Not a fan off 114 LSA's

I expected it to be less power; I thought the Idea was that it made more power at the lower RPMs than the M1 without losing so much high end unlike the kegger...  (Or making almost kegger low end with much more top end)….  Better yet, what about comparing the dyno charts at the mid/low RPMs?



*I just remembered, a while back someone showed the the M1 didn’t lose torque compared to the kegger on the (dyno) but that is obviously false in real world tests.

After researching this stuff for as long as I have now, I don’t trust dynos. Obviously I also don’t know a fraction of what you kids do though.

Did the powerband change at all?  Can we see both dyno sheets?  Doesn't affect my setup, I'm going with an Indy intake, I'm just curious

[msdnga]

Sure, I will post. The numbers where actually 2 off less, but the same peak rpm, peak TQ. No change in the powerband or how it responds on the street. Thats why I did the dyno to see what TQ gains would be affected, could care less about the peak HP.

Tell the Delphi boys making comments, that no GSC/PPH header ever compared to the Ram Pacesetter 1 3/4 long tubes either.  I went from 460tq with a LT  1 5/8 Hooker Header to 492tq by changing to this header on the DTS dyno.

Back on topic, no change anywhere in the powerband compared to a untouched M-1 2bbl.

Does it still magically gain you half a second at the track? lol...

[mopowar]

I think they gained .5 over a stock kegger. On a obd2 dyno anyway.

Thanks Marty. You just saved me $722.

[msdnga]

This may not be a fair comparison on a stock engine. But I was really hoping to gain 20 ft lbs and 4-5 hp over the M-1.

[SmokinMirror]

Thanks for the clarification Marty.

hey bad360rt, I didnt know indy made one... I'll have to check it out

[RATTLER360]

indy makes a manifold for us?

[SmokinMirror]

Marty, Im confused about... GSC, DTS?? 

[msdnga]

Sorry, GSM header and DTS engine dyno.
