Well I must say I am very happy with the results. Hard work paid off!

Each run I will show is the best of 3 runs with each setup.

Exact power mod list from filter to exhaust then electronics:
Vias delete stock IM (later home-made IM)
3" intake and stock MAF (later LRMAF and 3.5" intake)
NWP IM spacers
Cattman V3 Headers/Y-pipe
Cattman 3" catback with extra resonator
UTEC with Tuner to 7000RPM redline


Two notes before I get into the meat of things.

1. The stock MAF/stock IM tune on my UTEC is a thing of beauty... over a year in the making with absolutely perfect AF doing a flat 13.5 from 3000-4000, then settling to 12.8-13.0 until redline. The 3.5" dynos are all done with a quick and dirty tune that ranges anywhere from 11.9 to 12.7 that could probably see several HP gains if I'd had time to sit down and tune it properly. Alas, I did not.

2. I ran on my 18" street wheels/tires and power steering was connected. I am rather convinced that my lightweight track wheels and DRs alone would gain 8-10whp, and anywhere from 3-8whp from power steering. This car may dyno queen up 300whp SAE after cam install

Before all the testing and results, here are the final numbers. SAE, this is 280whp 258wtq. Went with STD because it follows the 275whp line on the graph so beautifully.



First test:

Stock IM with vias delete, stock MAF, 3" intake vs Stock IM with vias delete, LRMAF, 3.5" intake.


It still gains power, all over the RPM range, even with a inferior tune. Take that, naysayers.

~So the 8.2@85 in my sig was done with 265whp and major power dropoff above 6000....

Second test:

Stock IM with vias delete, stock MAF, 3" intake vs "s"SSIM, LRMAF, 3.5" intake



Looks like with a proper tune, this new IM will lose no power ANYWHERE in the powerband vs the stock one!

18whp peak gains and 50whp at 7000 RPMs!

Closer view on SAE smoothing 5 of the top end gains.


Next test:

Super short intake (TB>MAF>FILTER) vs "length tuned" intake (TB>MAF>PIPE>FILTER) that was tuned for acoustic resonance at around 6000 rpms.



So... super short SRIs are not the best way to go! This intake was 31" in length, giving a resonant frequency around 100hz (6000RPMs). It's obviously the better way to go.


First run on the dyno vs last run on the dyno



50whp gains at 7000RPMs... 20whp peak gains. All from 3.5" intake/LRMAF and custom intake manifold!

And last but not least... Video! I must admit, this thing sounds beautiful. All the people from the neighboring body shop were trickling over to check it out and I was asked at least once if it was turbocharged.

One more note... The smoke at the end of most runs is due to a TIMING cut rev limiter from the N2MB WOT box. It's still dumping fuel in.

ceffy is still faster. awesome numbers...wow

 

I can't mess with the honda killer

 

Since I know NmexMAX is going to ask, PM me email addy if you want runfiles.

 

like

 

Wow that's impressive

 

ive got some things to do... im drawing up the gameplan on a drawing board... good number man... i love... time to revisit the LR intake and MAF, ill also be creating my own intake but i want to experiment a lil also... i know you compare JP's numbers but remember he doesnt have the LR maf or a bigger intake.... however this is still very impressive

 

SO much win

 

It's on a different dyno as well. Hard to compare and it actually mean anything.

 

Agreed... great times non the less..... sparks mind if I hit you up in the near futur to fab up an intake for me, not like the one you have but I have something in mind of how I want it...

 

Shoot me your ideas and I'll let you know what I can do. Sounds fun

 

Awesome job man. Must be nice to see all that hard work pay off.

 

nice #'s

 

Awesome!! I wonder the result it would make on a FI motor...

 

Wild guess is the gains would be more than I got. The same resources that told me to go big on the plenum were saying to go even bigger on FI plenums. This thing is about 270CCs... lol

 

Holy phukk, imma poop myself ...

 

Im extrememly drung

 

Nobody could tell until you typed that. True story.

 

would love to see a all this next to a kinetix manifold as well

 

Great numbers. Glad all your work paid off in the end. Your findings with the SSI vs tuned intake are very insightful. In the video whats that noise at the 1:44 to 1:46 mark?

 

this looks and sounds sweet .i do not post a lot when i do you know that you are doing the right thing
emerald performance
do your home work before you spend your cash

 

I owned a Kinetix and I can tell you this for sure. I would need 2+ hours of dyno time to compare it to a kinetix because the POS kinetix doesn't even remotely port match to the LIM (round vs oval), so you need a custom ported LIM and NWP spacer. Then, the Kinetix is just a much smaller plenum, smaller elbow version of what I've made. I sold it because I didn't like it.

Are suggesting that instead of what I built myself, I should have spent literally 20 times more money on ITBs?

 

so whens the next track date? need to see some 12 sec slips bud!

 

Maybe next weekend for some pre-cams times. Not 100% though.

 

No, he's giving you props that you actually did some awsome homework, executed the idea, and got positive results. Nothing but love from him there sparks. Dont take it the wrong way.

 

Ah I see... I saw him say emerald performance, then do your homework before spending and thought he was telling me to buy ITBs instead lol.

I retract my retort, then. Thanks!

 

Yea, he's a good guy who's filled with knowledge and always there to give answers and advice to any questions you may have. Speaking of ITBs, a heads up comparison would be awsome between them and your IM. If you ever wanna set that up, contact him and see what you guys can do about it. It would be interesting to say the least.

Also, did you notice a difference in manifold pressure between the 2 manifolds?

 

Niiiiiiiice....lol

 

wasn't datalogging map pressure, but I do still get full vacuum as normal at idle and low throttle.

 

Come get me with that DEK...

 

Congrats

 

oh snap!!!... and this was the reply lol

 

Nothing wrong with a little friendly competition... Besides, he told me that the DEK would stomp me both on and off the track, so I'm waiting

 

did he really say that??? i say you look past that and head for JP... he told me the samething too, i highly doubt it

 

I'm aiming to do really well, but something tells me jaypee will keep himself a step ahead if I start to catch up. He was saying something about headwork before imp vs dom.

 

well this is good time to catch up... he dont seem like he's gonna be doing that lol... then again, knowing his sneeky **** he probebly will if he feels threatened im sure

 

Better watch out all dek's run 12.6@108 lol

 

Hopefully I won't be too far off that mark.

 

U crack urself up with sarcasm don't u???..
