Tunnel ram volume street/strip

Re: Tunnel ram volume street/strip

I bought the mag last night. I saw the single four lid on the ram and I see where it said the two fours making more power, but I did not see any numbers
Perhaps that is in a future issue? The main thing is that David said it worked really well, above the other manifolds
As far as cold starts go, I am used to that. I do hate the snow we just got, but it looks like we will have to put up with it for 4-5 months

Hello David
Thank you for your response
I have a Hot Rod mag that shows you with a 383 and in it was mentioned the fact that you where going to try out your collection of intakes
I did not think the updated articles where out yet? I did not buy this months issue yet, but I will tonight
take care

Re: Tunnel ram volume street/strip

I don't think a bolt-in restriction is going to help. I can't see it improving the signal to the carb, which is what the potential problem is with a tunnel ram. IMO, a long-runner tunnel rams is nearly the perfect street intake and they can be tuned to run perfectly throughout the rpm range. The only problem seems to be cold starts, and with 80 to 200ccs of pump shot available from two Holleys, it's not hard to flood the thing with fuel if you're not careful.

In a recent test we did a 383 Mopar, a Weiand tunnel ram made more power than an RPM Air Gap at every point from 2,500-6,500 rpm.

Hello
Has anyone played with tunnel ram volume ? I was particularily interested in the area between the two carbs and if it can be reduced for a street car( bolt in restrictor) then take it out for the strip
I just can't see why you need more than double the volume of a single 4 intake when running on the street

I am already playing with this, I was just curious if anyone else has done the same. Car is not finished yet
