Well after a long wait I finally dyno'd the K&N intake today. So here it is guys and sorry for the long wait. As for the results I'm very impressed with the gains from this intake but I've noticed after about 8 runs the power gains wasn't really consistent. I would say from heat stroke but after adding some engine cooling down time and adding another fan to the engine bay and to the intake itself it dyno'd better numbers after all. Here are the results. Enjoy

Dyno run 013: 379.1 whp 353 ft lbs tq K&N typhoon intake + Joe Z exhaust

Dyno run 008: 366.7 whp 343 ft lbs tq Joe Z intake pipe + Joe Z exhaust

I also tried a 4th gear pull to compare the difference between 6th gear pull. HP numbers were not off by much but tq numbers were off significantly.

Dyno run 016: 374.4 whp 336.2 ft lbs tq 4th gear pull

Dyno run 013: 379.1 whp 353.1 ft lbs tq 6th gear pull

From baseline stock numbers to modded dyno numbers

Baseline stock run: 356whp 333 ft lbs tq

Joe Z intake pipe + Joe Z exhaust run: 366.7whp 343 ft lbs tq

K&N typhoon intake + Joe Z exhaust run: 379.1 whp 353.1 ft lbs of tq

In the end there wasn't really 28.15 whp gain that K&N actually claimed(maybe closer on a DynoJet) but on a Dyno Dynamics Dyno a gain of 12 whp and 10 ft lbs of tq from just a short ram intake is pretty damn good to me.

Thanks,

Andy

Let me know how that goes.

Thanks ISF-88 I think you answered a lot of our questions. One last thing 93 or 91 for fuel?

Hey Andy,

Good dyno info..

BUT on the day you tested the below..

Joe Z intake pipe + Joe Z exhaust run: 366.7whp 343 ft lbs tq

.. I was pretty certain you stated & agreed that heat soak resulted in lower than expected dyno numbers in your Club Lexus thread.

Also, for comparison purposes, I hope you didn't use the highest dyno numbers after a long cool down period and added fans..???

In order to make a direct dyno comparisons like so, controlled variables should be kept the same..
ex: engine cooling down time, extra fan & correct gear used during dyno

Regards,

Joe Z

Your welcome and I use 91 octane.

To be honest that 366.7 whp run was the last and highest dyno run with Joe Z intake + exhaust and with cool down time. Couldn't get any higher after 5-6pulls in 6th gear.

Well Andy, I guess whay I am trying to explain to you is that, USING the Dyno Pulls or Graphs right after an extended "cool down time"..
Does nothing besides generate an inflated rear wheel horse power number...

The 8 minute engine shut down and re-start dyno. Generated a 17rwhp gain during our testing phase...

Here is an exmaple of that, during my R&D..
We never used the cool down numbers for accurate comparison purposes, in our 22 rwhp gain number for the exhaust and/or 5 rwhp gain number for the intake.

- As a disclosure to ALL, our Best Pump / Fuel choice is only 91 Octane for our IS-F, here in Southern California.

We also have this Dynojet graph of ALL the 6th Gear Runs with the New Exhaust System installed...

Run 11 (361.8 Rwhp / 356.4 Tq) = 1st run after initial setup and safety test spin on the dyno

Run 12 (354.8 Rwhp / 353.8 Tq) = 2nd run, which is right after the 1st run.
This run best represents normal operating temps.
This is the run we used to compare with the base numbers.

Run 15 (371.8 Rwhp / 357.2 Tq) = 5th run which was the last run.
This was just after the two 5th gear runs and a 8 minute shut down / cool down of the engine...
Best numbers of the day due to cooling period.

Regards,

Joe Z

Anyway, having the hood open is the best way you can get the single stage intake to show the difference. The real test would be when the hood is closed as it will have more trouble finding air to suck in.

I'll post my results this weekend. I just installed my Borla X pipe, Tom's drop in, and Joe Z intake. I had 336 for whp and torque on Dyna Pack before installing anything. I'm not really concerned about the initial nos, I am more after the gain after the goodies are in. To be continued...

ok so im new to the site... i couldnt help but to sign up when i read a few posts about the K&N.. i just had my car on the dyno in stock form and pit down 348hp and 300 torque to the rear... 91 pump gas... i ordered the K&N... went to put it on and the hardware was missing... no nuts screws brackets and so on... K&N sent the missing parts the next day... put the K&N on... K&N claims 28.5 rwhp.. EXPLAIN TO ME WHY I LOST 9 RWHP??

I think its great that you spent the time and money to dyno these and post. But I also think you've may have supported that the closed airbox with the JOEZ tube is the better path to modding based off your comment.

Would like to know your hp/tq level when you say it was heat soaked as this is how the car is going to behave the majority of the time in daily driving.

here are the numbers... 344rwhp and 298rwtq this is in stock form... i dont have the other sheet for the K&N with me but i will get and let you know asap... i will do as much testing as i can... im very much into cars... have a few toys 05 gt mustang full griggs sla roadrace car and a 07 shelby gt500 will 600rwhp that runs the 1/4 in 10.8 seconds to 11.3 seconds depending on weather... as you see i love cars

*note* we dyno'd the car in 4th gear... i see that some of you dyno your car in 6th...
im also doing this on a loaded dyno or load bearing dyno...

where you live could greatly effect your horsepower. the higher above sea level, the less horsepower you have. from your dyno im going to guess colorado.
