Indy Intake V2 done and tested.
As many of you know over the winter I did a lot of intake manifold testing.
In the end I found my favorite to be the Driven Innovations intake with a 3" throttle body on it. My car made excellent power on this combination and ran 10.01 at 142 mph on 93 octane with it and 9.42 at 155 mph on race gas with it.
In the process of all this testing Jim, Indy EVO on evolutionm, contacted me and said he has some ideas he would like to try and wanted to know if I'd send him a stock intake manifold.
I sent the intake and he went to work on designing some changes. The intake was then given to Wilson Manifolds to have the work performed on the intake.
I got the first intake back a month or so ago, the Version 1 (V1) and tested it. To my suprise it made more power up to about 5500 rpm than the DI intake and then after 5500 rpm the DI intake would slowly make more power gaining an 8 whp gain at 7500 rpm over the Indy V1.
Personally, I was impressed that this modified stock intake manifold could do that and do it through our 65mm throttle body.
Jim was not so happy. Seems he has a problem with being #2
I sent out another intake manifold to him for further development work. A week or so ago I got the V2 intake back here and my chin hit the floor with the work that went into this intake. It was amazing. Looking at it and starting to get a decent understanding of how the intakes work and why, I was really hoping for good things.
Yesterday I spent some of the day on the dyno with my RS dialing it in. The car had the Driven Innovations intake on it with a 3" throttle body. The first few runs with the car I was having a tough time getting traction or getting the clutch to bite hard enough. I lowered the tire pressure, strapped the car down tighter and got some heat in the clutch. After a handful of pulls everything worked perfectly.
Today I came in and swapped over to the Indy V2 intake and put the car back on the dyno. Today I was having trouble again getting the car to hook or the clutch to bite. I didn't know it but we are out of race gas here (someone emptied the drum and didn't say anything) and my car is so extremely low I knew I could only make a few pulls. Each pull the car "hooked up" better in the midrange but being scared of running out of fuel in the middle of a run I only made 3 dyno pulls and never got all the slippage out of the runs. This can be seen in the numbers and dyno graph I am posting here. Between about 5700-6200 (right at peak torque) is where the slippage was occuring.
Here is the dyno sheet (the solid line is the DI intake, the dotted is the Indy):

Here is the dyno comparison every 100 rpm on both intakes:
Driven Innovations w/3" throttle body
RPM Torque HP
3000 106 62
3500 140 94
4000 174 134
4500 238 206
5000 366 357
5500 467 499
6000 502 582
6500 493 617
7000 472 630
7300 464 632
Indy Intake V2 with BR 65mm throttle body
RPM Torque HP
3000 104 61
3500 139 93
4000 185 142
4500 258 225
5000 388 380
5500 472 503
6000 497 575
6500 491 614
7000 475 632
7500 467 636
I'm very happy with these results. I will be keeping the V2 on my car with our 65mm throttle body. I'd like to see what the car is going to run set up like this.
These runs were done at 34.8 psi of boost and the car was dyno'd in 3rd gear.
Last but not least is the long awaited for pricing.
The V1 intake is going to be $1350, you must send in a core. (I have one here right now I can sell/ship)
The V2 intake is going to be $1550, you must send in a core. (Those are going to be 2-3 weeks)

Amazing that a stock modified intake can keep up or even outdue such a great SMIM! Sucks, I just got a sheet metal intake before all this intake manifold testing began by you, and any word of an Indy intake. I still got the stock setup so maybe I'll eventually make the switch myself.
Thanks for testing David!

For those prices do we still have to send in a core?
Also I noticed you only went to 7500, what about the people that will be pulling it to 9k? It looked like the DI was catching back up in the upper RPM's , is it possible to do the test again to 9k?

Dave and Indy Congrats on the Good Numbers! Very impressive for a stock modified intake!
Dave now you have to try my race manifold thats sitting on you bench and see what that does and how it compares to all of these intakes

I'm on the phone with Indy right now and I can tell you this... HE'S STILL NOT HAPPY! I just don't understand this level of perfection. Better power to 5500 without a dip at 3900, then slowly pulling away uptop. Possible slippage at 5300. These numbers are pretty amazing. AND STOCK APPEARING, JIM, GET OVER IT!

All of Daves dynos are always to 7.5-8k. Would my manifold make more power at 9k+? Yes, I have no doubt about it. What everyone needs to understand is that this Stock modified manifold, its a great upgrade for people that want stock appearing manifold.

Could be... I'm still very interested to see how they compare from 7500 to 9k. Considering every drag evo I know shifts above 7500. I don't want to be a pain but thats a lot of cheese to spend and the rpms I'll be using most at the track aren't in the test.
