XRS + Injen Dyno Results Part II - Toyota Nation Forum : Toyota Car and Truck Forums

Steel Warrior · 03-07-2005, 02:43 PM

Well, I took my Corolla XRS to the dyno with the Injen CAI intalled, and the best run I got was of a neat 162.2 whp at 7600 rpm on 4th gear, and a speed of 122.92 mph. On the other runs I got 158.9, 159.6, and 160.2 whp. On the same run I got the 162.2 whp at 4th gear, I got 160.1 at 3rd. A huge factor according to the dyno technician: outside temperature. The runs were made at 92 F of temperature, so I am sure that all you guys at colder weathers will get better results. According to him, a gain of 3 or more hp can be gotten if the temperature was under 60 F. Besides the CAI the only additional mod I have in my XRS is a performance muffler. Thanks to djwolfd for making me go for an Injen CAI. If it wasn't for your post, I will be still running with the stock intake.

Nice results

Right in line with the Matrix XRS's I saw on the dyno a few weeks ago

Wow from looking at those torque curves VVT definately is not trying to get a smooth curve like the HP lol it is all over the place and drops to 98 at the cam shift.......ouch

Can you drive it in the rain with the injen? What I mean is, does or will it suck up water?

Thanks

Well, I drove it on Sunday under heavy rain w/out problems, but care have to be taken when driving through places that has large obvious amounts of water accumulated.

GREAT RESULTS!! any of u guys thing that the AEM bypass valve could be fitted on the injen CAI

coogarxrs · 03-08-2005, 04:43 PM

BTW what are u now getting in MPG as compared to w/o the CAI

Yes, probably, but its junk

coogarxrs · 03-08-2005, 04:53 PM

i thot it worked great

Yeah thats what they want you to believe so you spend your money on it.

Overall, I am very happy as to how efficient the 2ZZ is in putting down most of the power to the wheels, but the torque curve is quite weird. The torque dip that happens right before lift (down to 98 ft lbs) and then a sudden surge in torque (up to 118 ft lbs in 300 rpm) is another weird thing. I think Toyota does that on purpose to make the lift kick feel a lot harder and more dramatic??

Well, my technician told me that was the sole purpose. He even told me that Toyota admitted it in some old press notes last year. But that effect feels great

As for the bypass valve, I had one, not AEM, a unknown brand, on my Sentra, and it was a piece of shit. It wont protect anything.

what actually is the potential for hydrolock
