Went to the track yesterday. A bit of background. I have a pressure plate that doesn't hold pressure properly anymore and a 3.9 final drive I did 11.3 at 131
couldn't get my launching right quickest 60ft was 1.9 sec.
My first run I did 121 terminal, The clutch is was almost fully adjusted, but i then adjusted it as much as it would go then my terminals went up above 130.
I think when I get my clutch replaced and a 4.3 final drive I should see 140mph
I ran 1.6 bar on 50/50 mix on pump fuel, max knock reading 29 highest egts 750c 1382f post turbo, running .78 to .80 lambda.
Unfortunately My mate who I was racing hit a 10sec run so on our last race together I turned the boost up to 1.76bar added some more fuel in the cells, and forgot I have a skyline pump with in built 75psi regulator, I already run 50 psi base fuel pressure so when the boost went above 25psi the regualtor on my fuel pump kicked in, and my lambda went to .96 and bang at the top of 3rd gear. I'm wondering if I was running straight water if I would of got away with it?

 

Thats bad news mate

How much you injecting?

 

20% of total fuel 10% water 10%meth

I actually have another skyline pump at home with a fuel tank in the back garden as I was building a twin skyline intank setup so I could lower my base fuel pressure and not have to worry about the 75psi regulator built in them. Still should of rememebered though.

 

Agreed. If you have nothing to add, then don't just chime in to start trouble.

 

ABSOLUTLY!

When ever you come on here saying crap like “Alleged benefits” and “supposed” this and that, you’re only showing your lack of education. Also when you come in here demanding tangible data, saying crap like “he’s a vendor” “I have the right to demand tangible data” and being belligerent all the while. Is CLEARLY a thinly veiled attack on Rice.

Remember something pall. YOU’RE a “vendor” too. How about we start attacking you every day on your products and their “SUPPOSED” benefits? Are you prepared to defend yourself every day on your engines? How about we get RETed in here to work you over some more?

The truth is you have become a rookie engine builder. And you have had some success. So now you got a big head and you think you’re all that. You have a steady hand with a grinder, I’ll give you that. But time and time again you have demonstrated a clear lack of education.

I’ll even give you an example so we’re on the same page. When you challenged me on WI I posted a link to Ohio State University explaining gas laws, which showed you how pressure and temp were linked. It even had an embedded diagram showing you how the interaction works. Do you remember what your response was?? I’ll refresh your memory for you. You said “I wonder how it works in a RE?”.

Right now I need to tell you some thing. When you said that, EVERY single person that has taken a college level chemistry or physics class just went DOH... , and laughed at you. Because they know that no matter how special rotary engines (RE) are they will NEVER violate the laws of physics, contrary to your statements other wise. Just because you say so, doesn’t mean reality agrees with you.

I’ll let you into a secret; the laws of physics are immutable. (You can add that word to your collection) It can not be any different in a RE, than in the demonstration.


As you can tell I am no longer willing to sit by idle and watch you attempt to defame (that another word for your collection. Are you writing theses down?) Rice Racing.




P.S. You can use vocabulary to TRY to lend weight to your arguments all you like. But when it’s not backed up by a solid argument it only makes you look deceitful, arrogant and stupid.

 

25psi........... at 14.05 AFR. OUCH!

My gut says: no it wouldent have. But i dont know enought to say for sure.

 

ahh bad news Brian, do you think you have just taken out a corner seal?
What tyres did you run? 1.9 60ft you defo have room for improvement

 

Whatever the initial damage was is now a lot worse as I have to drive what must be a good 100 miles home with the engine in that condition.
MT drag radials at 16psi. I couldn't setup suspension properly it's all setup quite stiff because I haven't rolled my arches and the tyres will rub if suspension is set any softer. leaving the line at 4krpm I bog at 5krpm I spin too much.
1.76 bar and .96 lambda I suspect the apex seals are all dead.
I'm in no rush to pull the engine as there is no more events until next year now.

 

Yes I remember you have a T51 so nightmare in finding the correct launch rpm . With my coilovers I raised the back up by two inches and set it to softest , I get no rubbing issues with my Micky T Streets that way. I cut 4 1.7 60fts back to back with that method with a best of a 1.6. Defo when you get the rear suspension sorted you defo be in tens.
Im getting my car back next Sat , so hopefully be running at the last event at Pod, want to run some consistant 11s on low boost before I fit the WI system back on and tune it up

What was the best time you got Brian in the end heard you got a PB?

 

Hello WI freinds

I have been reading allmost anything the past 2 years about WI and got a pretty good insight how it works and why it would be good on a rotary, but it was thank's to this thread I at last bought a kit, and what a luck, Aquamist was about to launch their new HFS-6 WI and I was in the group buy ! I got the kit 5 days ago and I can only say, it looks promising ;o) I have spoken to Richard a couple of times and he is a very clever guy who knows everything about WI but he still has something to learn about the rotary he says, so he would be very happy if people who actually have installed WI on their rotary would post pic's/comments/bennefits and installation writeups about how people run it in their rotaries ! I have promissed him to give him a lot of feedback about how my installation/experience with the HFS-6 kit goes, right now I am just trying to figure out where to start ! maybe you guys could help me a little ;o)

1. Where is the best place to install the injector noozle ?
2. Should I use 1 or 2 ? (I think I can adjust the flow of the injectors from the controller)
3. I plan to use the washer tank, is it big enough and where would a good place for the pump be ?
4. If better use a trunk tank, any suggestions (pic's/installations)
5. Where to place the controller module/flow module/DDS3 gauge and how to run the wiring ?

Here is the specs for my car:

13B, rebuilt stage 2 modification stock twin turbo, Greddy intercooler, KOYO radiator, Blitz sonic power intake, Downpipe Pettit , Midpipe Pettit, Racing Beat catback, removed air pump, removed secondary valves, Boost Controller Greddy Profec B-Spec 2, Apexi Power FC (already tuned), Apexi Power FC Commander

Low boost is set to 0,6 High boost is set to 0,9 ( Dyno, see picture)

The car will mostly be a dayli driver but will be at trackdays once a while, I know it's a lot of questions, but I really hope you guys will help me, thank you very much.

I have some few more questions ;0)

1. What size noozle for injecting would you recommend for my setup ? I am running stock 2x550cc injectors for primary and stock 2x850cc injectors for secondaries.
2. Where would you put the flow module ? in the engine compartment (see pic.) or inside the car ?
3. How big should the tank be do you think ? in liter's please
4. I have looked at the RX 7 summer going with my kit, do you have to open the summer to adjust the flow according to fuelinjector size ?
5. Most RX 7 owners install the waterinjector noozle just in the beginning of the Greddy intake elbow (see pic of my engine) is this the optimal place or would you belive another place would be better ?

I am very pleased with the quality of the whole kit, it looks fantastic

I hope to begin the installation soon, and will of course post comments/pictures of it all.

Thank you very much.

List your complete mods, your boost pressure, and what you will be using the car for and I could help you out some.

 

Hello WaachBack ,

Look at the post I have made just before the one you answer, I should have written all the mods etc. you are asking for ;o) I hope you can help me, thank's a lot.

My nozzle is installed in the elbow, your kit will dictate where it can be installed.

If you have the option of running 2, you should, I pre turbo and one post turbo.

My controller is under my passenger dash.

The washer tank is big enough.

Start with 300cc's of water. You should not have to retune with that. However, you can always run more water, but, you will have to retune it leaner and also have a good ignition system.

 

Hello WaachBack

Thank you very much for your reply :o) I am just trying to get an owerwiew where to start installing my HFS-6 kit on my Rx7 FD3S, I am no big mechanic/electrician but think I can do it myself if I get some tips/instructions from other RX7 owners who have installed WI on their cars !

But actually, a lot of guys are talking about their systems on the rotary, but not many pictures and installation writeups and performance etc is to be found ? I would love to post my setup with pic's etc. when it is installed ;o)

Can you post pic's, installation instructions etc. of your system ? or can you direct me to a place where you know one can read/see more of WI on a rotary ? anything will be helpfull, thank's again ;o)

Best Regards
