Stuff I did today

[bioevolve]

No noticable difference between the two. Left is ITR, Right is A2 IM.

Switch Plenum/Pedulum (whatever) cover over and I always use RED RTV HIGH TEMP SEALANT:D

Also put in a rear strut tower bar, look good with the NEUSPEED strut tower bar (don't know why NEUSPEED calls their bar that, it doen't even tie the strut towers together, more like a c/d pillar bar to me.)

EVO exhaust will be coming in next week and something else (can't remeber what it was). LOL oh, duh, SS Earl's Clutch line, CF spark cover, and some other crap.
I didn't put the EBAY knock-off CIRCLE EARTHING ON YET (I got tired).

[civic hatch boi]

ar eyou gonig to be selling ur a2 intake manifold? i bet that'll give us a3's a great gain!

[Civicvtec1ps]

looks awesome
:D

[HondaMan]

Cool...what's the butt dyno tell you after this mod?

A2 and A3 Intake Manifold are Exactly the same. :(

I haven't drove it yet lol.

Oh, Forgot, I hand polished the Intakes tb inlet side and all 4 runners outlet side. 220 grit to 600 grit wet sanded, feels like smooth glass now, better than it was (rough).

[COMBUSTION]

Now remember smooth as glass does not always equal horsepower, infact it can do the exact opposite slowing down the air /fuel flow thus making the mixture turn into condensation on the wall. Personally i would make it slightly rough but not as rough as factory. Other than that looks good man!

[bioevolve]

Isn't condensation occuring in colder climates?
Only air is going thru there.
Anyways, I was going to go do a test run, but it's raining like hell here now. Like a monsoon, freaking hurricane thingys.
Maybe tomorrow.:(

[eurosteez]

Mind if I asked where you picked up the ITR mani. and How much $$$ it was?

EBAY $312 shipped, but ShowstoppersUSA.com gotz them now for $305 shipped I think. call them and ask for Chuck or Rocky.

[MrCivic03]

nice man lately u been loadin up on mods i mean i want to se pics of the thing assemled all together... sounds like u are goin to feel some nice gains with the IM and the evo and cai(or sri).
looks good nice work.

[bioevolve]

Yeah, all these mods and still no 200whp lol.
Once the EVO comes in, I will be selling my custom cat back 2.25" aluminized crushed bent, 2 silver bullets glasspacks (on backwards) with oval resinated/chromed tip. Will have to cut it in the middle to get it off, cuz I welded all of it together, except where it connects the back of the cat. Which I made a flange for. So When someone buys it, they will have to get a muffler shop to weld a 2.5" couplink where I cut it.

Sorry to be such a newbie, what does ITR stand for?

2001-2003 (don't really know what years) Integra Type-R, which has the K20A motor and 6 speed with LSD.

[intelli]

Thanks!:)

[fsugatorbait]

Where did you get the rear strut tower bar? not the neuspeed one; and how much was it?

[bioevolve]

www.tornactive.com $49.95 and don't forget to use your discount code for EPhatchers ;) . 5% discount code is: ephatch5off

[fsugatorbait]

thanks, good looks man! :cool:

[bioevolve]

Did test runs, booty dyno can't tell any difference. Probably 5-8 hp gain, but the engine revs much smoother now.:D Hopefully the new exhaust will help me feel both of them. No CEL's ;) Yet lol.

That doesn't apply to a dry manifold, as long as the port runners remain roughly the stock size. An Extrude-hone smoothing of our manifolds would probably net us 6-8 horsepower. In our case the smoother it is, the better. Fuel is injected close to the head, and an atomized mixture does not flow through the intake runners, so there is no possibility for loss of suspension.

[EP3_DC5]

FYI, there is a difference between the K20A2 and K20A IM. The runners are bigger and it breathes better. The K20A IM adds roughly 5hp above 8000RPM on the K20A2 engine. Under 8K RPM, there are no noticeable gains with it.

True that, runners are wider, tappered. Runner outlets and TB inlet are the same size thou. I need to take this thing to the track!

smoother = bad for flow.

there is more turbulence in the moving airmass when the finish is smooth. This occurs b/c the air moves at a different speed near the wall v.s. in the center of the moving air mass. this results in lower flow velocities due to the internal turbulence. A rough finish actually creates small micro-currents between the metal & air, resulting in less turbulelence in the actual moving airmass. This means that aside from the small circular micro currents that occur on the air/metal boundary, the actual moving column of air has less difference in speed between the center of the airmass and the boundaries - this results in higher net flow velocities.

it's totally counter intuitive, but it's the same reason why golf balls are dimpled.

[bioevolve]

What you just said, counters all the porting and polishing, also extrude honing. Makes no sense on internal engine flow.

Ahyhoo........Exhaust came in this morning (Thanks Chuck & Rocky at ShowstoppersUSA.com). Will put it on this weekend.

Will post more pics when done in a new thread.

not really, look around, and you'll find that very few engine builders will use a perfectly smooth finish on the intake ports on the head & outlet ports on the intake manifold. I know for a fact that on endyn's website, he strongly discourages mirror finishes.

http://www.theoldone.com/articles/b16a_head/

that's his article on head porting, and he says:


This might come as a shock to many of you, but this particular port would never run on one of our personal engines. It's not due to any deficiencies, it's due to the finish. A port finished like the one in the previous shot will perform just as well as this "cosmetically" nicer port, and since performance is king around here, we'd do the final sizing with the carbide finish for our own stuff. If it's our own, we don't need to bother with other's preconceived notions about "looks", so we don't bother. This particular head is for a customer and we feel somewhat bound to make the appearances "acceptable", so nobody will make any cracks about "unfinished" ports.

He basically said, the rougher finish will work just as well as the less rough finish on the customer's head, but in both cases, there isn't a mirror finish.

This also applies for piston tops - endyn uses a less than mirror finish on the tops of their pistons.

The most important aspect of head porting is how the ports are resized & reshaped. The "polishing" part is kind of a misnomer these days.

Nice work! Lemme know how you like that exhaust! Thanks for the shout outs!
