My Evo IX dyno session
 

Yesterday I swung up to DB for a tuning session with Shane and got some results that I am very happy with :) After getting a few issues sorted out last week everything seems to have come together fairly well.

mods:
Buschur Magnaflow turboback exhaust
Buschur intake with Vibrant dry filter
Buschur SS coated o2 housing
Buschur coated/ported exhaust manifold
Hughes/Scheides ported turbine housing
Buschur lower intercooler pipe
Joe P. MBC (set at ~23.5 psi)
Walbro 255 fuel pump

Got yourself a fun little car there kracka ass

Re: My Evo IX dyno session
 

Woot! Mildly modded IX's put out some pretty retarded power with the right combo of parts and tuning. I was there mainly as a cheerleader/evofanboi, but I did talk shane and hughes into trying out the lean cruise 'mod' I've been toying with over the last few months. Car cruises down the freeway at 15.6:1 with no ill effects.

This also shows that the ported manifold/hotside/ss o2 housing really make good power, shane was saying the average intake/exhaust/mbc/tune'd IX puts down 275-290whp on their DD, this is a solid 20+whp over that.

I am jealous hughes! My VIII put down 'only' 266whp when it was first tuned, maybe might have hit 275whp with a better parts combo. This car is 50whp over that!

Re: My Evo IX dyno session
 

Then lean-burn thing seems to work very well, the car drive perfectly smooth and I am saving gas :) I think the biggest improvements were made in the mid-range, it is now much fatter than it was before. I still haven't gotten a chance to really try out the car since the tune though. Traffic was heavy enough coming home yesterday that I didn't want to try too much; plus I just got off with a warning after being pulled over doing 80 in a 30 ("racing" a Lexus SUV).

Re: My Evo IX dyno session
 

Good stuff. Did you see my red 1g on the lift? :(

Re: My Evo IX dyno session
 

I saw it! Did not know it was yours, what's wrong with it? Too much superbleeding?

Re: My Evo IX dyno session
 

Endless clutch issues.

Re: My Evo IX dyno session
 

very nice

Re: My Evo IX dyno session
 

Thats pretty bad ass! What are your plans for it?

Re: My Evo IX dyno session
 

Nice. So to the EVO ignorant. What do you have to port on that stuff? Or is it fairly obvious when it's all apart?

And the "lean cruise "mod" ". Did you just tune that part of the map, or was there an actual "mod" you had in mind?

In any case, that would be a fun car, congrats.

And in a similar question to Joe's.. did you happen to see a blue NSX just chillen?(it's waiting for Shane to tune it).

Re: My Evo IX dyno session
 

No different than DSM stuff. Ported runners to match head and port outlet into turbine to match gasket. Do the same on the turbine housing and that's about it.

I have pics of the stuff from my car here:

The lean cruise 'mod' is just a tuned part of the map, and then tweaking the crossover point to open-loop mode.

I did not see the nsx or I would have drooled more, I've seen it around elite while wrenching a few audis with ktan and that is a damn nice car. PLEASE post up here results from tuning the thing, and PLEASE come take me for a ride when it warms up!

Re: My Evo IX dyno session
 

Yeah it is pretty crazy. When Luke (9guy9) had Shane tune his 2.3l Evo we were a little dissapointed with the power but very impressed with the torque. I dont remember the numbers exactly but it was over 300tq and upper 200s hp with out any porting but standard bolt ons. I cant remember if he had cams or not either but I think he might have.

Either way, those IXs are nuts, make the VIIIs look like sallys mod for mod.

Re: My Evo IX dyno session
 

Very impressive!

Re: My Evo IX dyno session
 

Right now probably just drive it and have a ton of fun! It'll get more mods slowly, but nothing extreme is in the works since I hope this car will be my reliable DD for years to come. I'd like to get a GM boost control solenoid to hold boost better up top and I wouldn't mind doing cams in the near future.

Joe - I did see the red 1G but had no idea it was yours. It looked pretty clean and to be in nice shape (as far as I could tell just looking through the window from the dyno room). What kind of clutch issues are you having?

Mo - I did not see the blue NSX, but if I had I am sure I would have gawked a bit. I was gawking at a hot looking white STI though :)

As far as the porting is concerned Scheides summed it up pretty well. The exhaust manifold is ported just like a DSM manifold is done, then it is JETHot coated or whatever its called. For the turbine housing we just gasket-matched and smoothed things out a bit down into the housing. Nothing extreme, just enough to smooth the flow. The ceramic coated o2 housings come decent, but we did do some grinding on the welds to smooth things out and opened up the wastegate passage a tiny bit more. We also hacked up the stock o2 housing heat shield to fit over the tubular unit to keep as much heat in the exhaust/out of the engine bay as possible.

Re: My Evo IX dyno session
 

I have a cam for ya chris..reach around?

Re: My Evo IX dyno session
 

Very nice numbers! And Swifty, I think he already knew about your cam. ;)

Re: My Evo IX dyno session
 

I know that..we've been talkin it out online for a while now..video chatting actually.

-A. Swift

Re: My Evo IX dyno session
 

...and I just agreed to buy it :)

Re: My Evo IX dyno session
 

Nice, i can say that you (kracka) and other evo 9s have swayed me a lot more toward one in the future, no where in teh near one though.

Re: My Evo IX dyno session
 

yea, I wasn't a fan of the mivec..still don't know if I am. But, for right now, I don't care for the payments..still...a definate car on my list to own.

Re: My Evo IX dyno session
 

As far as I can tell there is no reason not to like MIVEC.

Re: My Evo IX dyno session
 

That's pretty sweet! what other "free" mods can you do to that thing?

Re: My Evo IX dyno session
 

Nice numbers for the moddage!!

Re: My Evo IX dyno session
 

Congrats, lookin good!

Re: My Evo IX dyno session
 

variable cam timing is one of the only wonders on technology on a car that i like.
MIVEC is the bomb, i cant wait till someone figures how to put this on a DSM, and also make the head flow like crazy.

Re: My Evo IX dyno session
 

Still a few more el-cheapo things to be done that I'll be doing to my car too, stay tuned!

Re: My Evo IX dyno session
 

HKS did this years ago. But DSM'rs are too damn cheap to buy things that cost the price of a nice used dissem.

Re: My Evo IX dyno session
 

^well you just stated 2 good reasons, 1. HK(dollar sign), no argument about the quality or outcome of their product, but when is the last time you doubled the cost of a car for a little bit of power?
2. It cost as much as the damn car, obvious reason not to do it.

But honestly can you find it for me, i would love to see it.
Compared to hondas, dsms seem to be really restricted by the head flow, if the cost of the HKS conversion head was close i would be surprised to not see more do it, but i guess at that cost a fully built head will flow more or just as much.

Re: My Evo IX dyno session
 

Its not the head/port design so much as the cams. Stock honda vtec cams are huge by dsm standards. We had a thread on this not long ago.

Re: My Evo IX dyno session
 

Two good reasons for? I was just stating that someone had already accomplished: "i cant wait till someone figures how to put this on a DSM

And tons of people spend the cost of the car for a little more power. It all depends on the budget of who is playing, and how strongly they feel about what they want to do.

I just did a quick search for it, but no luck. I may have it in a magazine somewhere.

Re: My Evo IX dyno session
 

Yeah, my S2k VTEC lobes were huge.

Re: My Evo IX dyno session
 

oh sorry mo, i read it again, that came across wrong.
i searched HKS site no luck.
well as you all know, my dsm is about the budget, so far so good.
I didn't know floppy. But i am sure there is more reason than Honda's make so much more power than DSMs for power on the same setup than just cams.

SO whats next kracka? evo exh. cam? what else? some of that free ecu stuff scheides was posting about?
I was telling my bro, it looks like evo's are gonna be like hondas with all the crazy stuff they have for them.

Re: My Evo IX dyno session
 

I bought the BC 280 exhaust cam from Swifty, I need to get an intake cam to match though.

Re: My Evo IX dyno session
 

Throw that cam in there while you're waiting! What could possibly go wrong?

Re: My Evo IX dyno session
 

MIVEC is decent, tuning it on Evo 9s with stock cams mostly helps lower-mid RPM performance. If you had some aftermarket cams ground with the lobe centers retarded too far, then you would have more room in the upper RPMs to play around with tuning the MIVEC up there. At least it doesn't have to be tuned in a way overly complication way like the variable cam stuff found on the newer K20 Honda motors. MIVEC isn't as cool or have the power potential of the old school Honda VTEC though.

Yea, VTEC lets the Hondas run huge cams without all the idle, driveability, gas mileage, emission, etc problems.

Stock DSM cams have around .349" intake/.350" exhaust lift. Most normal aftermarket cams will be in the .400"-.410" lift range on the intake. A bigger cam(like the Crower Stage 4 415 Race or the FP3x) that will still drop in without major modding done to the head will have around a .425" lift. A drag race only cam that requires moving the valve guides deeper into the head to keep the retainers from hitting the valve seals and some serious consideration about valve to piston clearance might be in the .450"-.490". Then you have a stock S2000 cam that has a .498" lift on the intake.

Re: My Evo IX dyno session
 

Is this what helps evos make so much more power out of the box than dsm's?

Just looked up some specifics:
My HKS 280's have 10.8mm/10.2mm (.425"/.408") of lift (272's are the same).
HKS 272 DSM cams are 10.3mm/9.8mm (.405"/.385").

Re: My Evo IX dyno session
 

I hate you chris. I put down 333 on a dynojet with a much longer list of mods then you.
Anyone of the MN shops wanna give me a free tune if i drive my car to MN? (if my car makes it to MN)

Re: My Evo IX dyno session
 

They are? DSM's still have one of the best heads out there for flow, just go look at the ports on an SRT-4 and you'll see what I mean. The V8 guys spends thousands to get aftermarket heads that are anywhere near as good as our stockers, obviously the 2V vs. 4V makes a huge part of that difference. VTEC only makes a larger cam seem smaller for low speed cruising, they need it because they never made any torque anyways.

Re: My Evo IX dyno session
 

nice numbers, it should be a fun car to drive.

on the same dyno my VIII put down 30hp less with a 2.3L and cams. The IX head and turbo make a nice difference.

Re: My Evo IX dyno session
 

What other mods?
