it rusts like that when you only use water for coolant

it sat for 2 days before i took the head off... well, actually only for 1 and a half.  lol.

already working on a new build but i dont think it will be done till next year.  but thats a-ok with me.

[patsmx5]

Awesome numbers, badass build. I guess if honda had made awesome sleeves from the factory these things would be crazy.

[danz]

the setup will make way more power than 450whp once its back together.

i wont be a broke ass next time and ill pay for water meth or C16.


i officially want 600whp or a 9 second pass out of this setup, without nitrous.

new block is machined for 75.5mm 8.5:1 wiseco's

assembly today

tuning this week

racing this friday

[h2a]

nice set uo danz can you get a video of the next tine you go to the track thanks

[danz]

[ratcityrex]

Look at that cluster fuck!!! I love it!

[88dx]

If ur done before friday and still going to mission Ill head up as im back in town again 

[danz]

do it man i should be there.  i dont expect to do anything ground breaking but ill run her thats for sure

[danz]

started her up last night.

she idled ok, but needs a little work to the map before she will idle with 8.5:1 CR apposed to 9.7:1CR

i should be racing her tomorrow if the weather holds out!

reborn d16z6 turbo

Looks just like my shortblock did. Cept I'm too lazy to make it make power.

[Joseph Davis]

8.5:1 CR is too high.

Your engine bay, down to the air-water IC, looks just like my friend Timmy's - like over crowded ass.  He has a slow 476 whp setup.  You two would get along famously I'm sure.

[Gold DA9]

i love this car. Has me rethinking everything i was planning. Ive been wanting to do a water to air street setup for some time too.

You didnt take very long to rebuild it.

[Joseph Davis]

Has me rethinking everything i was planning.

Blatant success will do that to anyone with a brain.

With me i can never make up my mind. But  hell if i could pull it off i would be happy. Just dont know if I would do a tank or a radiator. Radiator style would be less obvious around here, since so many civics have FMICs. And everyone knows im SC.

[danz]

the reservoir system works well.  but the thing i dont like is how quick the ice melts.  even to do street tuning or dyno tuning im spending more money on ICE than i am on fuel.  its retarded.

if i am not one of the first 10 or so cars to make a pass in my class, my ice is melted.  its gay.

i want to run a stand alone AC system off a lithium battery that runs copper lines through the reservoir instead of ice.  i think that would be extremely sweet.



i am also considering running air to air, with water meth, and redoing a few things.  maybe even ditching the intercooler all together.

then i will use the water to air core for hot water, as my first stage fuel vaporizer.  then folllow in smokey yunichs foot steps and use a very small turbo as a check valve/homogenizer and wrap the intake manifold wit exhaust gasses etc.  try to build an adiabatic motor or do as good as i can.  throw it all in a gutted to the max CRX with low rolling resistance wheels and some tape aero mods and see what happens.


 id like to find a way to use the stock TBI system from a D15b2 but still be able to tune it...

and ideas JD?

[Joseph Davis]

Heatsoak is the bane of air-water setups.  While the AC based system makes my nipples hard, an air-air is probably the easiest solution.

[dvst8r]

Nitrous.

[Joseph Davis]

Nitrous.

Through the engine, pointless and kills the engine.  On the/a IC, expensive - try CO2.

[dvst8r]

Hmm nitrous has always worked well to cool post charger air temps for me. Like 430F to 65F.

[Joseph Davis]

Yes, but if the temps were 250F they'd drop to 7F, or hell how about what they do to normal 65-95 degree NA IATs?  Yet nitrous is still considered volatile.

Gasoline and diesel as sliiiiightly different beasts.

[dvst8r]

Is there a problem with running temps at 7F or even -30F? Is there an ideal temperature for ingested air for combustion?

I have always been under the assumption (and quite possibly the wrong assumption) that the colder the air the more dense, therefore the colder the better.

[Joseph Davis]

No, and there isn't a problem running 200F IATs, within a power range that the engine and octane gasoline can deal with. 

And, Colder = denser, yes.  This not being a perfect world, you offset any loss in airmass by raising the boost.

Here's my perspective that I don't think you're getting, or I'm not communicating effectively.  The accompanying oxidizer is the problem with using nitrous to "cool" IATs.  What the IATs drop to has nothing to do with the thermal assraping that takes place in the combustion chamber on boost + nitrous gasoline setups, and any extra airmass ingested due to cooler/denser intke charge is an icecube compared to an iceberg in the scale of things.  All nitrous + boost does is rip tires free and the engine doesn't last as long.  Great for dyno numbers, and as an academic tuning exercise, but fuck doing it in the real world.

[dvst8r]

Okay for something that is a street driven race car (not a track driven street car), where you expect to tear the motor down on a frequent basis. Still not worth it in your opinion?

[Joseph Davis]

Define frequent.  900 whp = 35-50 passes between freshening/explosion.  400 whp = 500+ passes plus street driving.

[danz]

this whole cold air is better thing is interesting to me since reading up more on yunichs ideas.

more is not always better as he puts it.  sometimes the quality of the mixture has more of a role in making power.

a truly homogeneous mixture, even better, vaporized fuel, would burn so cleanly and concisely, there would be no pockets of fuel or places for dual flame fronts to originate from.  the only thing to watch for would be pre-ignition.  less fuel would create more energy from a more complete burn.






so JD, can i tune a DPFI throttle body injection system?  do u know if its possible?  or am i better off to make a custom fuel rail and sleeve type deal post TB and pre W2A IC?






btw this has nothing to do with my drag car.

[dvst8r]

Once a season. Just a basic D eagles vitara's and an HX-35, with some spray for the track. I am sure I would spend more in tires, and fuel and transmissions then I ever would in refreshing a D once a season.

pgmfi.org, look in the OBD0 forum for EvilScribe.  Support was incomplete, but it may have been fully roughed out by now.

The inclusion of nitrous invalidates once a season.

I've wanted to experiment with this stuff too.  With a small VNT turbo so you can keep it spinning fast even under very low load.   The biggest problem is not being able to run the throttle ahead of the turbo to prevent exposing it to high vacuum with standard turbo seals.

[mrgreengenes]

danz, you should check out www.futurevehicletechnologies.com
it's just down the street from the shop.  Their original high MPG car (Ale) was a dual vtec D15B with a pre-turbo (VW k03) injectorator, and went to a vaporizer box then the engine.  I seem to remember it had a total of 5 injectors; 1 pre-turbo for gas mileage, and 4 in the regular spots, for power.  Running off a Motec.  It was totally cool, and George loves to talk about it.  I figure he'd be a great guy to get info to making a re-imagined CRX HF.
