I am putting a car back together that I bought that has a d1sc supercharger and a 408 stroker engine with pro topline heads and 60lb injectors. I have 2 intakes and was wondering which you think would work best with my engine.

I have an older intake that im told is a trick flow r and i have an edelbrock rpm II intake i can use as well.

the msd btm ignition has a 6400 rpm pill in it and the shift light has a 6200 rpm pill in it if that helps to figure out where this engine was making power.

any and all help would be greatly appreciated

What are you intentions for the car? The Trick Flow R might be a better intake for a track car, but the RPM II would probably be better suited for a street set up. I hope the engine has heads to....408W though stock E7TE heads means its gonna be corked no matter what intake you've got on top of it.

has aluminum pro topline heads with 1.6 roller rockers. will be a street strip car.... im not asking what it will work better with in which situation. I want to know what is going to give me the most power. it put 598 to the wheels with 587 ft lbs of tq on 93 gas before blowing a cheap head gasket with the trickflow. I am just trying to figure out which one will make the most power

it is that simple.... i have a dissassembled motor that im putting back together..... again. it made 598 hp to the wheels with the trickflow intake. I just want to know if it will make more power with the edelbrock intake or less power with the edelbrock intake.....

we are talking about a car that has made "x power" with a certain intake. I have another intake that i could put back on the car if it will make more power. I am looking to make the most power I possibly can

my intentions for the car have absolutely nothing to do with anything


I am sorry if this is coming out wrong, but im just looking to find out with amotor that made 600hp at the wheels, which intake will make the most power, the trickflow that was on it or the Edelbrock that i have in the garage

Again...no, it isn't that simple.

If building a dyno queen that does its best work running WOT down 1320ft of track, then by all means go with the Trick Flow R. But then if they heads and camshaft you’ve got aren’t designed to breathe deeply at higher RPM, you may gain no power at all…and just eat up low end torque and end up actually slowing yourself down.

If you drive the car on a daily basis, then a healthy torque curve may be of more benefit to you than peak power levels...in which case you should stick with the Edelbrock. Then again, if you’ve got deep breathing head castings along with a healthy cam profile, the RPM II might be choking you out a little on the top end.

Without knowing what other modifications are done to your engine along with supporting components (Other intake mods, exhaust size/components, vehicle weight, rear end ratio, etc) then you're pretty much flipping a coin as to what horsepower gains to expect.

Make sense?

AND AGAIN IT IS THAT SIMPLE.......

What i plan on doing with the car and what is on the car other than what I stated is irelivant. If i wanted to know "which intake will give me a better power curve" or what works the best i would have asked that question. I told you the power the car makes with the trickflow intake. i know how the car acts with a trickflow intake. obviously im ok with it on there since i have been driving it with that intake on it
I JUST WANT TO KNOW IF IT WILL MAKE MORE HORSEPOWER THAN WHAT IT IS CURRENTLY MAKING IF I SWITCH INTAKES OR IF I SHOULD EXPECT A POWER LOSS?

it is just as simple a question to answer as "whats your favorite color?"


i have explained this for the 4th time now. if you can not or do not want to answer the question that i am asking, then stay out of my thread and let someont that can or will answer the question do so......

Awesome...have it your way. If your combination is some big secret and you don't want to give out any details for whatever reason, feel free to take all of the "shot in the dark" answers you're going to get because of it, to heart. I hope it all works out. If nothing else, I’ve consistently bumped your thread back to the top for you. :)



On a side note....in the future, you might want to check that attitude of yours. The whole more flies with honey than vinegar sort of thing. ;)

Don't ask questions if you already know the answer Henry ford. Don't bash people trying to help you as you obviously don't take help very well. If your as smart as you think you are, you'd realize different intakes make different power at different places. The TFr will help more in the top end but if it's not a track car your sacrificing low end for no reason as you won't be high revving driving it to work. The rpm II is a very good street intake and pretty good on the track. It all depends where it's gonna see the most time.
 
#11
Sooo......do you see a situation where one intake may make more power at different rpm ranges than the other? Or one might make a couple more HP....but have a completely different power curve?

So, yeah....I'd say its not that simple either.

If you're so handy with the tools....its an intake. Put the other one on and see what it makes. It would take like an hour. That's the most accurate way of comparing the two. :shrug:

Wow, the OP is obviously a moron. I hope no one else wastes their time reading this thread. PEAK horsepower numbers don't mean much if you refuse to tell anyone the intended use of the car or your complete top end combo. Are you building a dyno queen, a track car, a street car, or a combination of street and strip? Why is that question so difficult to answer for you? What RPM the power and torque is made will determine streetability, driveability, and overall temperament of the car when it's complete. Don't ask questions you don't want to hear the answer to. How about your car will make 9,000 horsepower with the edelbrock, and 9,006 horsepower with the trickflow. That's a pointless answer to your pointless question, and it's what you want to hear anyway, isn't it?

If you know how to make it, then you know what works and what doesnt.

Ive seen a Stock Cobra Long Block put down 505rwhp. Youve got 105 more CID's, Better Heads, and only mustered 598rwhp? What gives? only 93 more HP than a 302 ??????:shrug:

Not Bashing the Forced Induction guys, but Boosted appliactions always make power, so that leads guys to think they know how to make Power.

Making Power N/A is much harder than boosted. If you can make a ton of power N/A, then you Know how to make power. The combinations more critical to get right to do so.

yes u will lose power with the eddy intake. the only intake from eddy that u should use would be a vic JR, victor or a super victor with a chp elbow. The 351R is just fine.

what cc r the topline heads?
