haha....

i know what you hinting

eagerly awaiting better pix of the graph and some comparison....wish I was as dedicated as you are with taking dyno's to see where and how much you are gaining

Atlas.46

i think you should go back in like 2 weeks after the ecu adjusted for the intake and see what the numbers are. :-p

Sonnick

Sigh. This isn't the best comparison graph considering the spikes, but I gained power everywhere with this intake. From 4500-6300 I gained between 5-10hp/tq. The only place I didn't gain anything is from 6500-6800 (redline). And remember, these gains are over my 3" intake. It's not like I went from stock to 4". I gained 'only' 2whp peak and 8wtq peak, but the midrange says it all.

Again, this intake is probably a solid 5-6" longer than my previous intake, which probably helped the midrange. I switched to the 4" about a month ago, so there was plenty of time for the ECU to adjust.

^^^ Another thing what I wanted to ask is what filter are you running?

I am running a 9" long filter ()

Sonnick

Lol. Velocity stack

anx1300c

iTrader: (2)

Actually saw this over on v6 perf. earlier. Awesome numbers. You're making more torque at the wheels than the 3.2 base TL is rated at the crank (233)!!

4" intake is definitely on the radar for spring. Gotta get all new brakes and get my hood/tops of fenders painted first. Shitty Honda clearcoat....

Sonnick, can I haz pix

Sonnick

Here are 3 comparison graphs. Swoosh, a pic of the CAI/Velocity stack are at the bottom. 1 engine bay shot and 1 shot to give you an idea of the stack setup. 2 sets of pantyhose as the filter (sigh)...

Red - Before 4" CAI
Blue - After 4" CAI


Green - Bolt ons/Stock ported manifold (222wtq peak)
Red - 3.7 IM/TB/runners (227wtq peak)
Blue - 3.7 IM/TB/runners & 4" CAI (235 wtq peak)


Red - Bolt ons/Stock ported manifold
Blue - Current setup (3.7 IM/TB/runners/4" CAI)


Interestingly enough, it seems the 4" CAI got rid of the 'dip' when the butterflies open. I'm assuming the AFR was straightened out at that point? But I'm not really sure. We couldn't find the AFR 'gauge,' otherwise I would've gotten that as well.

I'm very happy with the gains of both the 3.7 IM/TB/runners and 4" CAI. I would've liked to see the powerband drop off a bit later with the 4" CAI, but I guess that can be attributed to the longer length. I really only lost power in the last 200 RPMs, and even then it's only about 4-5whp. The midrange (4000-6400) gains of 5-8 whp/tq make up for it and then some.

Not sure why the peak torque values aren't there, but they are above the 2nd graph.

great fawking post for anyone who is debating to do this mod....

Look at the power and TQ increase....17whp and 13wtq is awesome !!!

and thank you for the pix....I wanted to do a velocity stack and a longer pipe but was a puddy to put a panty hose filter on a tub hanging soo low....

Sonnick

Yea the 3.7 manifold/TB/runners/4" CAI is definitely the next step for anyone looking for more than the I/Full exhaust route. And there are plenty of gains to be had.

Lol, yea man the pantyhose filter was a longshot. It's worked thus far although definitely not the best choice for a DD.

What is your exhaust setup in those^ dynos?

kingkong_dav

that is a big intake

Sonnick

PCDs/custom Jpipe & merge collector/3" midpipe with a large Magnaflow reso/dual 2.5" piping to Dynomax Ultraflow mufflers.

Atlas.46

So where does your intake place the velocity stack???? behind the fog light hole with some space or up against the bumper?

Sonnick

IIRC, it's on like a 30-45 deg downward angle about 3-4" from the fog cutout. Fog was kept in since its glued now lol. I think it would definitely make a difference on the street even if it didn't show on the dyno.

Thanks what she said

NvrDwn

Remember guys, I could become a vendor IF I get enough interest.

gwiffer

iTrader: (7)

Sonnick, do you think a 4" CAI (like yours) would give 5whp? 10whp? over a 4" SRI right off the TB?

Sonnick

^ Sorry Gwiffer, I hadn't seen your post until today. I think a 4" CAI will definitely outperform a 4" SRI directly off the TB. Our engine bay gets pretty hot, so a CAI is a better option on our cars. I think you could easily gain 5-8whp throughout the powerband switching to a CAI.

Haven't updated this thread in awhile. I don't have any real updates, but I have gone back to the track a couple times. 'Best' recent pass is a 13.77 @104.04 on a 2.29 60'. Now, I bought DRs and have been using them. Only problem it was only my 2nd time on DRs and I did my burnouts in the water box, which I now know is a no-no. I'm hoping to get my 60' down in the 1.9x range so I can pull some bottom 13s next time out. Vids of semi-fail passes below. Although I was neck and neck with a C5 vette coupe on the 13.7 run.

i dont know if i should start a thread in this section for my car...Sonnick what do you think.

My heads have TL parts in them and my j-pipe says its for a TL...lol

Sonnick

F*ck it. That's how it went with me lol.

Sonnick

I took a trip to Xenocron today, where they have the "Mainline" dyno, or as Simione said "Painline" lol. Heartbreaker at it's finest. This is the same dyno a built K24 (12:1 compression and Stage 4 cams) made low 240s. I was fully expecting the numbers in the graph below. Nothing changed since my last dyno. Best pull was 235/194. First run, my AFR was around 13:1. The second and third pulls it dropped to 12:1. Interesting. He said that's probably because of heatsoak, so maybe I need that thermal intake manifold spacer, huh?

Atlas.46

boom!!!

Sonnick

FlashPro tune appointment tomorrow w/ Chris Miller @ 1030AM. Will update with results. Last time on this dyno I made 268/228. I'm hoping for 276/235. I'm very interested to see how the powerband looks from 6800-7200, and also how the powerband acts with different VTEC points. It's currently set @ 4700.

swoosh

iTrader: (5)

and brother I thnk you are being very very optimistic with the expectations...I think you will be in the 280's, ofcourse depending on you current AFR readings....

I know some cars run pretty rich and hence gain less, but some run lean and have more potential after a good tune

all the best man....

Sonnick

Thank you, sir. I'd rather be surprised than disappointed though But all in all, my AFR was pretty solid last time on the dyno, around 13:1. I'm hoping timing can be advanced a little bit. I know the TL has 11:1, but my motor is only 10:1, so I'm assuming I would be able to run more timing than the TL before knocking.

swoosh

iTrader: (5)

yeah 13:1 leaves little room for richer AFR....but yeah timing is what i bet they will be adjusting a lot in that case....

and yes, you might be able to run more timing....i wish you would get some head work done and run 13:1 CR and a little higher timing....all i hear is power power LOL...


also wanted to ask you how you like the velocity stack as compared to the filter....am thinking of replacing my filter with that and a panty hose

Sonnick

Lol. Tbh, I'm not sure how it differs from the filter. I never dyno'd with a 4" filter and then a velocity stack, but it's worked fine since day 1. There are 2 layers of pantyhose around the stack, which has stayed tight for almost a full year now, through torrential rain, etc.

swoosh

iTrader: (5)

I might order it when the filter on mine gets old....

bouncer07

If Sonnick is already getting that much power from the engine being untuned, he should have no problem making more up top as well as a little more down low. Should be a different beast tuned with more power up top.

Atlas.46

We really need to meet up and go on the same dyno. To really compare. I still am running the stock intake manifold too.

Oh and something came in the mail today. It even came with a license plate frame

bouncer07

Don't forget, it comes with One sticker as well.

Did you break the dyno?

Sonnick

Ha sorry I made 274/238. Gain of 5whp/9wtq over the last dyno. All gains came after 4500 RPM. I will post the dynos later.

Atlas.46

Update your sig.

anx1300c

iTrader: (2)

You always set your sights too high!

Step back and take a more holistic look. This is a 3.0 making an honest 274 whp with bolt ons and a tune, and still on stock cams/heads and 10:1 comp; an engine that was rated at only 244 bhp from the factory. It's impressive to say the least.

For the straight up number whores, this car would break 300 on a Dynapack.
