KulG35 and I went and dyno'd our cars with the K&N intakes installed on Saturday, so we will both be posting results soon.

Here's a brief rundown of our findings... I saw a peak gain of about 6 HP at around 6200 RPM's, however, my peak HP figures that came around 7000 RPM's were pretty much exactly the same with both intakes (294.3 Vs. 294.1). I also saw a pretty decent torque increase almost across the entire RPM range with the largest increase of 4 - 5 lb-ft coming at about 6200 RPM's.

KulG35 got much better results, but he got did his baseline a different day, so he was able to switch out intakes last weekend and give his ECU some time to adjust. I don't have his exact dyno figures in front of me, but I believe he gained 3 - 4 Peak HP and about 6 lb-ft Peak Torque (running almost 310 HP, with FI exhaust and HFC's). He also had a huge torque gain across the entire RPM range from the stock intake, so his dyno charts look very nice.

My results were not as good as his, but I actually switched intakes there on Saturday, so I didn't give the ECU a chance to readjust to the new intake, so I was actually running a 1/2 point richer with the new intake, which was probably hurting performace. I may try to go back in a couple of weeks and do a few more pulls once my ECU has a chance to readjust.

Plese note that all these runs were all done on a DynaPack dyno, so they can't be compared to anything done on a DynoJet. From my experience, the DynaPack runs about 6% - 7% higher than a DynoJet. To give you an idea of the difference, I used to have an E36 M3 and it ran 271 HP on a DynoJet and 290 HP on a DynaPack with the exact same mods, so about 6.6 - 6.7% higher on the DynaPack. I'm just happy that my G puts out more HP stock than my M3 did with several thousand worth of mods.

Here are some new pics of the engine bay with the K&N intake and BB grounding wires installed.

My thanks to KulG35 for helping me install the K&N intake in Church's parking lot on Saturday!

 

Thanx for the write up and great pics. Looking foward to seeing the charts.. Great job..

 

Sounds good, considering you didnt lose any power like many other intakes and gained torque as well, cant wait for the charts, and thanks for putting up this detailed write up for the community..

 

Do you notice a difference in the sound? How noticeable is it, if so?

 

If you're just cruising, it's the same as stock imo, but when you jump on it, it roars and sounds great. I'd say you start to notice it around 4 or 4500 rpms.

 

anytime boss

 

D_cecc said it perfectly.... At idle and cruising on the highway from 2500 - 4000 rpm's the sound is very close to stock, at least inside the cabin of the car, but once you drop the throttle and both throttle bodies open up... Wow! does it sounds sweet. Sounds like a completely different car... almost like a Jekel and Hyde type personality. I love it!

 

So can I still order using that link?

 

Yup. Someone else on here just asked me the same thing a couple of days ago, so I just talked to Jason the other day and confirmed that he will hold the group buy link open for a few more weeks... So, just follow the link and he will get you taken care of. I see that you are in SoCal, so he will probably have it dropped shipped directly from K&N in Riverside, so you should have it shortly after you order it. I actually got mine the next day!

Good luck and make sure to let us know how it goes!

 

Thanks for the feedback! I'm just waiting for some cash to come in and I'm going to order it. I love how it looks in the engine compartment and the power increase, as reported, is definitely worth the price! The nice sounds are just the added bonus.

I wanna do the Magnaflow exhaust setup that has been talked about here, too. Couldn't imagine a sweeter Christmas gift than that!

 

^ No problem, admdavid. I think you'll definitely be happy with the K&N system. It's by far the most professionally made intake I've seen for our cars. Fitment is great and it uses most of the stock mouting points, so everything is solid.

I also plan to post up the dyno charts, as well, once I get a chance to scan them in.

I still haven't decided what kind of exhaust I want to go with, so I'm curious to hear how you like the Magnoflow system once you get it, so keep us posted.

I got to drive 16 laps around CA Speedway in a full blown Nascar, so that was a freaking awesome Xmas gift from my wife... albeit, the car was rev limited to about 150 mph, but it was still fun as hell!!!

 

i went ahead and ordered the intake from this place and just received it today! i ordered on 12/15 came 12/23. im excited to get this on the G asap.

 

But the site says that its about $350 instead of the 261.95 shipped as quoted by "SuckitUp"

 

damn, it went up. i didnt even notice that.

 

They probably made a mistake and corrected it.

BTW, these look so similar to Stillen et. al in design. Why does this one gain while the others lose?
