On another note, I like the color scheme on the engine.

1 turn key hot or cold. This is the cold start.

Untuned run, normal driving shifting at 3500 rpm. 43mm waste gate making sweet noises.

Clean sleeper setup.
Dyno coming soon. Blow off valve goes on the silver pipe with the temporary blue coupler.
Progress video.

11.5 AFR's at idle? Was that warmed up? Sounds like you have a bit of a hard start on the cranking video as well. Lets see some dyno video and drags trip vids.

Semi cold idle at 11.5 AFR, goes to 13.0 after 30 sec delay from the Haltech. Still dialing in the cold start, that start was on a base map.
Dyno vids will come after the motor is broken in.

you are running meth right?
sounds good so far. Let's hope you hit your goal

Yes I am running meth. The car is also built to handle C17 which we will be running on the dyno.

I'm still not a fan of the IC placement.... do you plan on venting your hood at all to accommodate it? I just feel like it is susceptible to heat soak where it is now with minimal air flow through it... :dunno:

Nice build though, can't wait to see it tuned

Thank you RM. My setup is similar to a turbo II setup. I was going for a sleeper setup.

The IC actually uses the stock air tube that feeds air directly from the nose to it. A shroud is being designed to keep the air from rushing over the IC. If this is least efficient , then I will move forward to getting a vented hood.

that's why I asked about meth. you're going to want it with that placement. with my shitty intake placement I see 110-122 degree intake temps on a 70 degree day. that skyrockets to 177-240 if sitting at a light. with these 40 degree days I'm seeing 89 degree intake temps while cruising the highway.

Yep, that is why I had to fabricate the tray and get it coated. Texas in the summer = crazy IAT's before. That is one reason why I want to see WOT track video or side by side runs of this car.

IC, this may actually work nicely with a shroud, good thinking; depending on where you live it may be all that is necessary; I know it would probably be enough up here where I am.

If you do go the vented hood route I would try and dig up an old thread by Jeff (MazdaManiac) as he did a similar set up but ran shrouding to the bottom of his intercooler then vented it out through his hood; very similar to the top mount on a stock Subaru STI. I can't remember the name of the thread though.

Update: Car is running beautifully. 1 key starts hot or cold. Car stays at a nice constant 202 degrees. We were street tuning and got to 7 psi before she leans out. Even with a walbro 255 and ID 1000CC injectors its just not enough to compensate for the volume of air. So I am doing a return style fuel system and a secondary pump next week.

Even as is , the car comes alive at 2500 rpm and pulls pretty good till 5500. Feels funny having torque so low in the spectrum. Can't wait to get the fuel system done so we can finally tune her and get her on the dyno.

Watch how you implement that...or you can make things worse :(

That sounds awefull low to be running out of fuel. Before you put in all the money of a return system check your fuel pressure. What g/sec are you pushing at 7 psi?

Something "ain't right " . Suggest it's to do with scaling/latency of the ID1000s .

You have plenty of fuel pump and plenty of injector to go well past 7psi.

Guys, he has and expert builder who knows exactly what he is doing. The guy builds 400HP automatic Renesis's.

Yep...there should be enough injector for 500+ HP...so something else is going on.

Did some googling, and it looks like AFR for methanol is 6.4 or 6.5:1, so we would need more than twice the fuel capacity compared to gasoline? Is it correct to assume this?

Yes if he was running straight methanol, but he's not and it's just water injection. That fuel setup should be plenty... I agree with the others it is probably a tuning issue.

Or you could read the first post ....

Update: fuel system came in finally after being back ordered, will be installed this weekend. Also I will be running methanol, when we was street testing the car, no methanol was being used. Car will be able to run ethanol also.

Car was leaning out on a base tune. Not a full tune. Remember we was just testing the car on the street to make sure she didn't overheat, etc.

Should be tuned within the next 2-3 weeks.

updates?

This......... I am looking forward to updates, :lol:

Fuel system goes in this Thursday, street test/tune this weekend. Next week Dyno. I'll have video of the car to show Saturday or next Monday.

Car is running beautiful. KyoRad installed and running a few degrees cooler in this balmy low 90 degree weather we have been having in FL lately.

So ....how did all that go ?

Just saw the build with RA super seals. Motor will not last as the seals will tear up the housings in short order. Premix might help but doubt it. Not hating but been there.

Bump for updates on the pro tuning.

^^trouble-maker

Update : We went to Titan Motorsports and used their dyno. Unfortunately the car made as low as 177 whp to 450 whp and everything in between. The dyno was seriously off. By the time the tech came back, Titan had to close their doors.

On a high note, my tuner was able to get 15.5 lbs of boost safely. And I still have plenty of fuel to go at least 18-20lbs. The dual 250 WB FP are working flawlessly.


In 2-3 more weeks we go back to the dyno. The car pulls from 2200 to 9000 effortlessly. As a test I lined up my '08 Lexus GS 350, 303 HP on tap it runs consistent 13.9'-14'0's. With my tuner behind the wheel of my Rx-8, I am happy to say my Rx-8 put about 2 bus lengths on my Gs. From a dig or a roll my 8 just pulls hard.

From that sloppy bridge port build to this , it's a contrast all the way around!

177WHP-450WHP? Sounds legit..... Got any video? Looks like you are running a tad bit rich.

At first it was running very rich, then he dialed it in for 11's AFR , the meth kicks in at 12lbs of boost. I have video of him dialing in the AFR, I'll try an post it.

Tuner was dialing in the AFR's, that was about 3/4 throttle. When he was going full throttle my buddy forgot to video tape it. Next dyno session I'll get some WOT pulls.

Your turbo isn't big enough for that ..... but good to hear it is going well .

Thanks! Will see what he can do, if he can't get farther then what he has already made, I am fine with that. The only reason why he didn't go further is becaus Titan had to close shop. The car is very fun to drive and is plenty fast for the street as is. Anything extra would be a fringe benefit.

Pic of my engine bay.

Looks promising. What fuel are you using?

93 octane. My system is set up for E85 as well.

I forgot to mention I am also running all 6 ports with this setup. Most guys who run turbo have to run 4 ports.

Would be very surprised if you actually get 15.5psi at 8000+ rpm doing that with your smallish turbo .IF you do ... your IATs must be very high !
But I don't mind being proved wrong ;)

Actually I make 15.5 psi at 7900, lol. I am
Not to sure about the IAT. My EGT was a little on the high side before I added the meth injection. Once my tuner had the meth set up, the EGT came down considerably!

You think a 5558 is small? It's not huge and it's not tiny. It's a mid range turbo. The PT 5558 is rated for 35 psi and 650 whp max.I know I never will see that on a Renesis. But I also know that I am not even close to maxing out this turbo where I am in the tuning phase.

590 actually (just checked their site) optimistic Precision piston flywheel hp ...............
Covert that to realistic Renesis rotary whp and you are looking at more like 360 (and blowing really hot air while doing it ) .......

what turbine housing is fitted?

My bet is low 4xxhp with race gas or E85 and MI

flywheel hp.................... yes

It's not to big, .81 something, have to look at the box it came in again. Which is not infront of me at the moment.

Brettus also I have a large jet to inject the meth to cool the air down further, also my IC is getting fresh air piped in from the front of the car. We designed a shroud to keep the cooler fresh air from going up and over the IC.

If you like a video of the car hitting 15.5 PSI I can provide it. I also hit 15.5 psi at 3000 rpm.

15.5 psi is barely over A pressure ratio of 2. So to hit 450 you would be 225 at the rear wheels before the turbo, and that's figuring no thermal losses or the volume of meth. Each of those are highly unlikely, all 3 at the same time would make it a unicorn.

Who said I hit 450? Where are you pulling this number from? Where are you going with this?
