"Indy Technology" for the EVO intake manifold
First I want to say that I feel very lucky to have become friends with Jim (INDY EVO) here on EVOm. Thanks for taking the time to talk with me and share a lot of knowledge with me!
The knowledge that he is bringing to this side of the industry is rediculous.
As many of you have followed along I have tested some intake manifolds in the last few months.
I went back and re-tested three of them once the testing was all over. Along with that testing I tested 3" upper i/c pipes, 3" throttle bodies, 3" outlets on the FMIC, two different inlet locations on the FMIC. I just haven't stopped testing. Yesterday alone there were three sets of different cams in my car I was testing.
Today I started swapping out intake manifolds on my RS. So you guys understand, I don't really care who makes a part, if it makes the most power I am going to run it. With that said what is on my car now is the Driven Innovations intake manifold with the 3" Hypertune throttle body. After changing the throttle body over to the 3" and re-testing it against the Hypertune and HKS Kansai I found it to make better power than both by a small margin. The cost is less than 1/2 so it was a logical choice.
I put Indy's intake on the car with our 65 mm throttle body. First pull the car made more power across the board over the DI intake/3" throttle body. A few more to dial in the AFR's boost and it was still the clear winner.
I was very skeptical as there was a fairly major weather change in the last 24 hours so I put the Driven Innovations intake back on my car and dyno'd again.
Good thing I did. The power was up from yesterday's testing. Now with both intake manifolds being dyno'd back to back on the same day I had excellent data.
The crazy part is that Indy's intake manifold was the winner up to 5900 rpm and by 8,000 rpm was only down by 8 whp. This is freaking insane considering the gains I made from changing from a 65 mm throttle body to a 3" was about 15 whp!
Boost was 35.24 peak on Indy's test. Average AFR was 12.1:1. Starting AIT was 75 degrees, ending was 77 degrees.
Boost was 35.00 peak on DI's test. Average AFR was 12.0:1. Starting AIT was 75degrees, ending was 78 degrees.
You can't get a test much closer than that. Both tests were done in 3rd gear.
Here is the dyno sheet comparing the two runs. The first run is Indy's intake manifold (solid line) and the 2nd run is the DI intake manifold (dotted line).
Next so it is easier to figure out, I will list this in numerical form below:
So there you have it. I think I have all the data put up there correct, if not call me out on it
Hard to type all that in columns and keep it straight.
Indy, your first attempt at this is unbelievable. I am really looking forward to your next attempt! I will be sending out another intake manifold for you to sculpt!
THANK YOU for all your help.
BTW, for everyone else. No pricing has been established yet. Right now Indy wants to see if he can't tweak the intake more to bring the power up over 6,000 rpm to meet or beat what else is out there. Can it be done? I'd have to say with the results on a first attempt it definetely can be.
Once the next one is finished I will be running another dyno test on the part. As soon as we are at a finalized state on this it will be released.
Thanks for reading.

Holy Sh*T
Man I wanna say something about the Indy intake manifold
Indy great job bro
You are a jenious man, I guess being around all those cars all those years has paid off
Thanks Dave!

I know you said that you tested tons of parts. By chance did you test your ported stock intake manifold you offer on your site. I was just curious as to the difference between that and Indy's. I would assume a fairly substantial gain?

Pretty nutz that a modified stock intake just beat one of the best sheet metal ones out there.
Also impressive that the DI manifold beat the Kansai.
Odd that the Kansai beat the DI on stock TB but not on a 3".
And I'm upset I bought the Kansai now!
Cash down the drain!
