I have the standard stock ported intake and 65mm tb, I wonder if I'd benefit going to the Indy v2 or Driven. I've yet to see it compared

 

Damn impressive!!

Wonder how is the Indy perform on the small turbo like a Green? And thanks DB for the time and effort to test each of his products.

 

This is how you benifit from DI manifolds!

I would guess that V2 should perform similar.

 

thanks for taking the time to locate that post, I missed it over there.

so he gained 36 whp and 32 ft lbs of torque
same timing
same afr

changes:
Driven intake and tb
10* cooler ambient
a custom 3" upper i/c pipe and modified our race FMIC to a 3" outlet

that's inconclusive to me since too many things were changed.

 

No matter how I test someone has something to say..........I am not putting the DI intake back on the car to test the car up to 9,000 rpm.

For comparison though, the Indy V2 is actually pulling away at 7500 rpm. Here are the numbers from the end of the pull.

DI w/3" Indy V2

RPM HP HP

6700 624 624
6800 627 628
6900 629 631
7000 630 632
7100 631 634
7200 631 635
7300 632 636

As you can see the DI is about flattened out, the Indy V2 is picking up about 1 whp per 100 rpm still.

As soon as I get some more fuel I am going back on the dyno and will get everything warmed up and strapped down tight enough to make some good pulls, I hope.

This is about the most impressive thing I think I have ever seen. A few months ago I thought all intake manifolds were BS from the results I had seen in the past and how fast my car was on the stock mildly ported one. Then I did some testing and found that there were actually quite a few fabricated intakes that did in fact pick up power. Now here we are a few months later and have two guys with enough talent (Jim and Wilson) to pull off modifying a stock intake manifold to perform better than any other combination I have tested, it is quite amazing.

Yes, you do still need a core, I don't possibly have enough intake cores to provide. I am sending down what we have to Wilson to have him start some for us but I will need cores to replace them.

Anyone with our 65 mm throttle body already will be able to bolt that directly to the Indy V1 or V2 intake manifold.

Taking into consideration the cost of this manifold and a 65 mm throttle body, yes, the price gets up there. Having the best overall curve and peak power costs money though. It does allow the use of all the factory sensors and emission components.

Now that the product is done I hope Indy doesn't mind me going into more detail on how it is built. I want to explain though why the cost is what it is. (It is NOT because myself or Indy are greedy either, we are making very very little on it. From a profit stand point I am much better off selling any of the other intakes)

The intake manifold is shipped down to Wilson Manifolds where it is cleaned. Then it is cut open and modified on the inside. The internal modifications make the plenum larger and the runners shorter. The runners are welded up and re-shaped and each runner is balanced so they all flow the same. The intake is then welded back up both internally and externally and ground back down. It is then shot peened and when you get it back, from the outside just looks like a brand new intake manifold, with a Wilson Manifold tag on it.

This isn't just some hack job, it is a freaking work of art. I am truly amazed it can be done the way it is.

 

Awesome post Dave. This is a real eye opener on what you can do to make a car go faster.

Can you put a 3" throttle body on the V1 or V2? Or is it just not big enough?

 

mellon, you would absolutely without a doubt benefit from either of the intake manifolds. I'd expect a 30+ whp gain from either one from what you have.

I have DI's in stock here on the shelf if you want to try one. The Indy Intakes are going to be a few weeks.

 

A 3" throttle body will not fit on the Indy Intake, there is not enough room.

 

I'll make a purchase on down the road for sure, right now I'm focusing on getting the built BR 2.0 and BR head work funds ready I'll see what I can do on my current intake/tb setup then do one of those intakes when my wallet quits smoking

 

I completely missed page 2, haha, sorry guys.

I will run this intake manifold, Indy V2, higher in the RPM's when I put the car back on the dyno. I do most of my testing up to around 7500 rpm to save wear and tear on the car, I do HUNDREDS of dyno pulls on this car so it takes a toll on it. I have said this before but if I type my name in the dyno computer to look up my charts it gives me an error that says, "Search exceeds 1,000, re-define search." So the car has well over 1,000 dyno runs on it. Think about that.

I did say "650" yesterday. The dyno main screen when it finishes a run (I have said this before too in many threads) shows an uncorrected/unsmoothed number on the screeen. When you view/print the chart that number is less unless the smoothing for the chart is set to "0". I run our dyno with the smoothing on 60.

Yesterday the highest unsmoothed run from yesterday was 650-522 but the run was lean, the next run was when I added fuel to it and that is what I tested against today with no other changes.

I made reference to the "650" in passing, I didn't say it was the final number or any details. Just said the car was doing well and made "650".

Also, through all this intake manifold testing I did NOT re-dyno our standard ported intake with the 65mm TB. The two parts gain right at 15 whp over the stock intake/stock TB. During all this testing I used a stone stock intake and TB to test against.

 

Good info! Awesome work Jim and Dave. Thanks for having a test mule to do this with Dave! If you need another one with something closer to a stock setup I may be able to donate my car for a few weeks if I can get one of these awesome TB/Indy Intake manifold setups! LOL Dave you have PM Sir.

nice numbers

 

So prices with core or not (i assume with)? Please update your original post or people will keep asking for the next 100 pages..

 

DB, I imagine that the manifold is difficult even for the most experienced people like Wilson Manifolds. I don't think that the price is out of line, considering the work involved. I'm sure that the reputation of Wilson Manifolds says it all. This is one vendor that we need to support to keep the good stuff coming! They've only begun to make offerings and this is a great start.

 

still no photos of the unit? 1500 is steep for a stock manifold!

Is'nt the di manifold only $850?
