Now with alot less verve!

Default Injen CAIntake (and maybe others) dyno testing on a Stage2 STI

Hey guys,

The mad dyno testers are back (Chris&Gregg). This time we have been feeling some really weird juju in response to Injen's claim of 30hp from their intake. We've also read lots of places some supposition that the stock intake is practically limitless. We went aways back and didnt find any good, applicable, objective dyno testing of the Injen intake (or really any other intake). We just so happen to have a stage 2 car sitting around (with headers on it now )... and we happen to have an Injen CAI right here too.

Im a big believer in the benefits of a cold intake charge, but I couldnt dream up any decent tests that would show the effect of under-hood air (short ram intake) vs external air (CAI) on the dyno. I'm open for suggestions. I like the APS CAIs, the K&N CAIs, and the Injen CAIs.

I believe that the MAF housing in the Injen intake (and others) are not perfect simulations under power of the stock MAF housing. Fortunately, the car learns its way back to stock like AFRs within a reasonable amount of time, IF the change isnt much (Insert debate here... I know, I know). Therefore, I think we should baseline the car on the dyno and log it on the street, then install the Injen and let it learn for awhile... and then dyno again and log on the street again, showing learned fuel trim correction. As with the header test, we'll show you all the changes in weather and try and keep everything as close as possible. All dyno'ing will be on our faithful local Dynojet and results will be available both uncorrected and with the error-prone SAE correction.

Now, when we did the header test we had an *excellent* response form folks willing to help out with the dyno tab. Again, this time, Chris&Gregg are willing to foot the bill for the test of what we have mentioned (stock, and Injen). We understand that SOME folks would like to see how a Perrin Panel Filter dynos out. Personally, *I* could care less. Some folks may want to see the APS intake. So here's the deal...
If I get $50 in contributions, we'll dyno and log the Perrin Panel Filter too. If we get $100 and someone loans us an APS 65mm CAI, we'll dyno test and log the Perrin PF, the Injen, stock, AND the APS. If a vendor want's their CAI dyno'd too, and can put up the $50, we'll do it as long as they understand the wordy disclaimer below.

Current Intakes to be Tested:

1. Stock
2. Stock with a Perrin Panel Filter
3. Injen CAI
4. K&N Typhoon CAI

As before I'll list all contributers and their amounts right here so that you guys can see that Chris&Gregg arent in this for the $$$ (or a Perrin Panel Filter, for that matter ).
Contributions can be sent to the paypal address [email protected].

Contributors:
1. aaronwrx - $20
2. Ryan Perrault (nic?) - $10
3. Unabomber - $20
4. Chump - $10
5. ekw - $10
6. TylerTR - $10
7. Evodon84 - $15
8. JDGrimm - $10

We'll keep y'all posted on when and what in this thread, and the final total results will be assembled and truncated in a second final thread.

After intakes, we will be looking into dyno'ing different vendors Stage2 tunes.

Let the games begin

Disclaimer: Contributions from participating vendors will be accepted only up to the $50 it takes to dyno their part. If there is enough protest from the forum members, we may send you the $$$ and the part back.
All parts will be returned to vendors following testing. If the part is a stinker (ie it might hurt the car) and we realize that early, we reserve the right to apply the dyno $ to other parts and just send the stinker back. We will only dyno production parts that are available for purchase by anyone here at NASIOC. If we feel that we got a ringer in any way, we'll make as much fun as we can of the vendor here in the thread, and we may send you a non-ringer part back . Vendors and manufacturers may use the results that we find ONLY related to their part vs. stock, and not of other vendor's or manufacturer's parts. Please PM me with any questions.
