Another intake thread

[RR Fan Dan]

The engine builder and head porter both told me that I'm leaving about 30 hp on the table by not using the RPM, but the look is more important to me.

This is where I’m at. Look is more important. I was hoping to keep the dual snorkel, I would switch the intake only if I could keep the dual snorkel. If there is not much difference between the stock 71 and an aftermarket I’m keeping the stock one. I’m not drag racing. A few tenths of a second and mph ain’t gonna kill me.

so what was the difference when you went to the 71 intake from the Torker. lost top end power ? better throttle response ?

No seat of the pants difference, and it was a Torker 2 I took off. I don’t know what the motor was making because I didn’t build it. Definitely heads cam intake exhaust but not sure specs. The car is currently under restoration so the motor is going to be torn down and rebuilt too. Hence this thread as I’m planning on what that’s going to look like.

I would guess the porting helped 15 HP on the ch4b plus an alum intake is a lot easier to port than a stock iron intake.

Bill told me 10-15 which is fine by me. He also said that I spoiled him because he's used to porting the iron manifolds and the aluminum intakes are like porting a stick of butter...lol

Why does it matter in the context of this thread? The OP has hood clearance issues and and cannot figure out how to make the air cleaner work with any tall intake. So with that my position is simply that he can use either the Performer, or CH4B, and turn his 600 hp motor into a 475-500 hp engine instead of a 400-425 hp engine.

Thank you for keeping on topic. Not sure I would lose 100 hp though. More like 30-50 was what I was thinking. And that’s probably going to be at the high rpm range which I’m not drag racing so it really doesn’t matter because the car will rarely see high ends of RPM.

must be more than 300 HP to go 14 seconds and 100 mph with a roadrunner. stock roadrunners were around 15.5 seconds 1/4 mile times.

That’s exactly what I ran in 81 with my motor and best of 15.01 but had 4.56 gears and basicly all stock

That’s the article but it used to have a chart at the end comparing them all. It doesn’t say what the gains were from each one. And the iron intake they used is not the premium one I have.

I’ll be watching this thread to see the requested results for hp numbers on the dyno vs rear wheels

So now I’m confused. You stated you wanted to build a 700-800 ho motor and building it around the dual snorkel air cleaner? Sounds like a lotta hp for a street car but like I’ve stated will be watching the dyno and rear wheel hp numbers. With my 70 air grabber car this might be my street/strip set up on a 3400lb car

Thank you for keeping on topic.

everything posted on here was on topic. you asked how to use the stock air cleaner and was told how. you asked about different intakes and also were told. after 1967 all the intakes were no different and the 71 intake is no prize even though you think so. you're going to lose closer to 75 HP with a stock intake plus the stock air cleaner.

No not really. Very vague.
