$1800 for 20-40hp over a max ported lt1/4 intake is worth it in my book. If this gets released, I'm going to be on the list. In a max effort n/a motor, once you hit a certain threshold (~415 whp on stock castings and still mostly streetable on an lt1, more on an LT4/AFR setup) power becomes hard to find.

 

I you were to place a twin 52 mm throttle body on this intake instead of the two seperate thorttle bodies, why would this be hard to build?

I'm working on making the TQ curve healthier and more HP in the sub 7,000rpm range with this one.

I think you can get more than 415rwhp out of stock castings, but you have to spend a lot more money than most guys want to. Ken's heads that are sitting in my shop right now have gone that extra step. When I put this intake on the bench I am going to test it with his heads to see how it flows. Flow is only a minor portion to making this thing work, but it is important.

It looks like you are beating a dead horse here... I am not sure what you are looking for by continually bringing this up.

Steven's intake is well a hogan. Which goes through all the steps that Bret, Mindgame and others have already explained... this is why 99% of people should not build their own intake. Maybe 15% of the people on this board can weld up metal, flanges, plate, etc and make their own intake... but is it going to work well? It MAY work ok, but it will be no where near optimal... there is a good chance you will even hinder the engine and make less power. As said many times if you want to make your own, go nuts but all the fast and experienced guys have already said to leave it to someone who does this for a living and knows what they are doing.

 

Bret, you're saying the intake you are designing will be most beneficial on a max effort stock bottom end motor such as mine and many others like it. or atleast thats what you're aiming for?

i would at the very least be interested in it

how exactly is the testing going to be performed? magazine comparison like....stock vs. yours (Kens) vs. fully ported and welded LT1/4 intakes? or just a before and after of a particular setup? dyno time....track results....CFM number comparisons etc.....?

 

Who did the heads?

Also, can we get a rough idea about the cam...

Pass emissisons? Idle speed?

Just want to get a good idea of the overall combo in relation to predicted HP numbers. Maybe you can answer that when the car goes down the 1/4 .

Blackstone in CA did the heads.

They are actually LJ's old heads.

 

To add to simple's question, and to clarify something said earlier - 30# injectors may even be too small for someone running the hypothetical H/C N/A 350 here??

"36, even 42.." I believe was mentioned earlier. I was just wondering if someone could expound upon this idea, because I am in the process of buying injectors and assuming I were to invest in the "BRE PRO RAM" (I love the name btw ) then I would want to size my squirters right the first time in anticipation for the future, aka when we hear how ken's car does!

Anymore input on this in particular? 42 sounds huge, but then again this isn't the average chop-n-weld manifold...

thanks guys

 

Ah....the light bulb goes off. I'd be interested to see what those make with an LTx intake on an NA motor...Go figure .

Definitely more work in those than your standard stuff. I will wait and ask other question after the numbers come out . Good luck .

Exactly what I meant by power becomes hard to find. It's there, but it isnt cheap.

 

It will be most beneficial on 350's to 383's staying under 7,000rpm. It will bolt right up to stock castings without port matching so it will work very well with a stock bottom. We can match it to bigger ports and make it work on strokers without a problem.

The main application will be heads/cam cars on a stock bottom.


I will flow everything on Ken's heads, stock intake vs. BRE Pro Ram. I'm not going to port match and weld up a intake just to flow test it on Kens heads. The flow is not the key to making power here but it should flow better than a stock intake.

The dyno results should speak for themselves. Ken doesn't want to drop on a stock intake and then tune the car and then go to the BRE Pro Ram and then tune it again.

I wish we could do it so it was all kosher and have two equal dyno comparisons, but that's not going to happen, so do you want a dyno test with a optimized BRE Pro Ram and a non tuned setup with a stock intake? I don't think that would be fair even though I would show better gains.

Bret

 

Nope, don't give out specs or even hint at them.


Pass emissions, nope

Idle Speed is not going to be 700rpm is my guess.


I don't have predicted numbers as of yet, but I would guess more than most people are seeing al la more than 400rwhp.

If Ken's car is setup for drag racing then yeah, that would say a lot. If it's not then it doesn't say much. I'm just afraid that it will make too much power and everyone blows it off as a BS number like they do with Joe's stuff.

I care about dyno numbers for the most part because if the place is honest and testing is done right then you get a good ballpark of what is going on. Drag times depend on driver, tire, car, setup, track etc.... the motor is only a small part of it, but true it is a important part.

If his motor makes some crazy number it's because it's a system of parts working together. The heads, the cam and the intake. I'm happy with his heads and the rest of the stuff is under my control. The KEY IS IT'S A SYSTEM!!!!

We have some flow numbers on his heads now, but I want to see them on our bench and with the intake on to see what's really going on. I do have a feeling that they will move some air.

Steve's LTX intake is more for VERY high RPM like 7000+ because of the added plenum volume. The BRE Pro Ram is based around more plenum volume than stock and a longer runner, this will make much more TQ and should improve the average power numbers in a big way.

Bret

 

36's should work the best here, Ken's 42's are big but they will work.

Bret

 

Hey Brett, man Ive got to give you props on putting all of this time into this project which is lookig to be a real success.

You may have mentioned this earlier in the thread ( but thats alot of posts to read through) how much Hp and TQ gains are you looking at over a bone stock LT1 intake that all together is making say, 330 rwhp granted it is dependent on aot of other stuff too. but just roughly. Ill definately be in on this in the future though.

Later man,
-john

 

It's more for a heads/cam setup more than anything. So it's hard to say what it would make on that.
