Direct Port EVO IX rs HFS3
 

Hi!,

I am from Spain, (Zaragoza).

I year ago, I bought a Mitsu Evo IX RS with some upgrades, turbo, inyectors, exhaust, ecu...etc etc...

This is my car:

Well, now I am boosting around 24 Psi, then, I have some questions for calculate my nozzle.

- Inyectors 800cc....Max Duty 85%-----0.85 x 800cc x 4cylinder = 2720 cc.
- W50/50 with 15% ---------------------0.15 x 2720 cc = 408 cc of nozzle

Then if I want to install the following system:

I have my first question...

To calculate the nozzle, How much nozzle I need to divide?

408 / 4 (direct port) = 100cc....
408 / 5 (direct port + post-ic ) = 80cc?

Thank you.

How much power are you making first?

Re: Direct Port EVO IX rs HFS3
 

Now the car runs 1.6bar and 420 hp at flywheel and 520 Nm with 8 degree if advance.

I want 20-25hp more, with more advance, cooler IAT and 1.75 bar, and furthermore, I want to clean the inside of the engine.

I will adjust my LINK ECU with dual map with more Advance and leaning the AFR.

Re: Direct Port EVO IX rs HFS3
 

I would shoot for a minimum of 500 cc total. 400cc for the engine and 100cc for the intake.

Re: Direct Port EVO IX rs HFS3
 

Or even more flow at this power level. I run this at half the HP.
More gains more after a remap, especially for the direct port jets I have found since going from 0.3mm to 0.4mm-C size jets.
Don'T expect much IAT drop. That's not how WI works anyhow.

Re: Direct Port EVO IX rs HFS3
 

I inject 44% Water/Meth (500cc) to Fuel (1130cc) ratio in a 1.5L engine @ 1.4Bar running 40s Ignition Timing on boost.

Theory is your guide........ Trial is your best friend

@Rotrex - What do you mean by "That's not how WI works anyhow" ?

Re: Direct Port EVO IX rs HFS3
 

OK!!!Thank you for replies!!!,

I will get 5 Nozzles 0.4mm with 110cc (I think B type nozzle in 0.4mm). Then, I will need the following?

I have a question...the inlet Port diameter 4mm / 6mm which is exactly?, sorry, but I am new in this world...and I want to play with Aquamist and my car..

And...the kit is:

Package contains:
- Multiport hex manifold -----------------------------------------------OK
- Checkvalve jets with compression fittings --------------------------These are the 4 nozzle of 0.4mm type B?
- One 1/8 NPT jet adaptor (one per cylinder)-------------------------OK
- One checkvalve for post IC jet --------------------------------------This is the nozzle for the post IC...is another 0.4mm Type B?, or I have to buy the nozzle?
- One 4m to 1/8BSP compression fitting (hex port + 1) -----------What is this exacly?
- 4mm high temperature PTFE hose----------------------------------OK

Thank you.

Re: Direct Port EVO IX rs HFS3
 

- Direct Port bundle: Type B is 110cc/min. x4 (806-501B)
- System comes standard with 3 nozzles, choose one of them a type B (806-301B). Not need to buy
-4(mm) to 1/8 fitting. This is the fitting for the 5th port on the hex manifold for the Post IC jet. (mis-print)

See below with numerical caption:

Package contains:
1. Multiport hex manifold
2. Checkvalve jets with compression fittings
3. One 1/8 NPT jet adaptor (one per cylinder)
4. One checkvalve for post IC jet
5. One 4m to 1/8BSP compression fitting for post iC jet (hex port + 1)
6. 4mm high temperature PTFE hose

I mean with this than unless you inject large amounts of methanol, especially pre turbo like you, IATs won't drop that much. Most of the knock suppression happens due to the water droplets in the cylinder and the high octane of the methanol.

Your system is a bit special, indeed and shows significant drops in IAT. But you also have no change cooler. Your system is optimised to both drop IAT and get mix into the cylinder.

if you inject way less past a charge cooler, not to much IAT drop will happen. Most knock suppression is due to in cylinder effects.

Your install is also a good example what you can achieve with WI given you inject enough. 500ml/min for a 430HP engine in the OP' car is not what I consider a lot.

:-)

I am looking forward to some warmer weather to properly test the new bigger direct port nozzles.

Good to hear you car is still running strong.

Ok, I have a Used HFS 3 V.2 (I think) that a friend sell me:

I think that all I need is the following, tomorrow I will re-check.
