I just wanted to show the final setup on a Customers street car. The over 700 pulls were kind of just to see what it could do. Map wasn't smoothed out on the race gas stuff because we knew we would not be keeping it on there.

This is what you can achieve with proper parts and set up.

It is a largeeeeeee street ported motor.
Rotary Aviation SS
Balanced, side clearance, and studded.
Nothing else as far as lightened or anything special

Has a lot of good reliable parts, and a whole set up of oil pressure, oil temp, and Fp all being collected by the Adaptronic and able to cut power incase of failure.

The set up is a new style Custom billet 6 blade BorgWarner s475 with a 4inch downpipe. Extreme Turbo Systems front mount, Full Function "Everything".... Motor mounts, fuel rail, oil pedestal, ect. Xsessive LIM and oil pan, Mocal dual oil 24 row oil coolers. Cj motorsports twin bosch 44 setup with all stainless lines. Sake bomb AEM coil setup......And much more

Stock upper and Throttle body. Not even ported

But one of the biggest things for his daily driver setup he is on now is the Methanol Injection system

It is one made by Devils Own. It is their black dry sump tank, pump, full stainless steel line setup, and their dual nozzle set up. With their 50/50 mixture. All being controlled with the ECU


The cars final numbers on 93 octane and methanol were 612whp and 458wtrq. This is what the car left the shop on. Now the customer that wanted this build did not want a track car, drag car, or race car. He wanted a daily driver. Yes a 600whp change oil, plugs, check methanol, fill up at the pump daily driver. This is what he got.

After much abuse, roughly 3-4000 miles, reg oil changes, a few sets of plugs. The car is still driving just like when he left.

I just wanted to share an update on the car and what can be achieved with the cars when set up right and routinely maintained even at higher hp levels.

 

very nice, thxs for sharing. Will it be at DGRR 2015?

 

I'm a firm believer that higly modified cars can be daily driven. But to achive those goals its about quality of parts, builder and tuner. If you lack in any of it you wont get the best results!

 

the power curve is a perfect example of what happens when you run a reeealy large turbo at modest output levels.

the S475 is 800 rotary hp capable. it has a 9.5 sq inch compressor and a turbine wheel more than double that of a GT35.

which explains why it made 225 rear wheel SAE hp at 5000 rpm. the setup is down 120 hp to similar overall dyno plots at 5000 and 60 at 5500.

so who cares about 5000/5500?

if you shift at 7500 (see dyno chart) you are looking at

4350 into second
5175 into third
5400 into 4th

this is not a criticism of the build or tune and all concerned are to be congratulated for a really nice FD.

i am simply drawing attention to the need to appreciate a broad power curve. if you care about winning races you need power when you find the next gear.
there is something to be said for running a touch larger than necessary turbo as it doesn't have to work as hard but when you end up w 225 rwhp at 5000 perhaps
there is a mismatch.

a 600 SAE FD should make at least 350 at 5000 and 400+ at 5500

perhaps instead of a mismatch there was something that cut the run short rpm-wise. if the engine is run to 9000 the next gear would be plus 1500 and be getting into the true
powerband of the 475.

^ This is a pump gas tune. The car made over 700WHP on race fuel.

 

as i said, i am impressed w the car, but making the point that there is a lot of 5000/5500 give up which you will visit if you shift at 7500 as on the posted run.

here's a comparative from my dyno files, all adjusted to SAE. power plots are at 5000, 5500, 6000, 6500, 7000 and 7500 and then the total. i picked the neighboring three plots above and below.






here's a comparison between the 475 and my GT4094r at 25.5 psi. this turbo will make 630 at 29 psi so it is smaller than the 475 but is a 600 hp turbo. note the power diff at 5000/5500.





it is evident that the 475 really runs top end and of course is nowhere near it's potential in this run but it is also evident that there is an associated cost. it will be very interesting in 2015 as the new wave of killer turbos is evaluated as to whether the cost of 700 is as great in the 5000 area.

my bet is for a large pickup in the 5000 area.

You should spend less time creating and posting these worthless comparisons and more time getting back to the 5 year long fiction thread.

 

Super badass, congrats

 

This car shows what an awesome supercar FD can become without cutting corners and commit to doing things right.

I don't think HC was out of line for suggesting a potentially different result with slightly different turbo setup. Personally, I'd love the see the same car with a EFR 9180 (which I think would fit my personal driving style better with the power curve likely moved more to the left without losing too much up top compared to this turbo). HC just needs to get his 9180 setup running so we can compare.

 

Thanks for the compliments!

The Owner is very strict on maintenance and always wanted top notch parts. This makes a huge difference on making a Rotary reliable at this power level that is driven every single day.

 

I'd Love to hear it

 

I will try and dig up some sound clips of it. The car is extremely loud to say the least

 

seeing cool results like this makes me get bit by the rotary bug again .... I miss the fd life . ive been without one for a bit over a year and its killing me .

sweet results . get some video posted on this thing!

 

I hope you get back in it man, that black FD of yours was soooo clean.

 

Glad we can offer some motivation Here are two videos with some clips of it!

(watch last few seconds)



The car is under the knife as we speak for some more upgrades!

 

It's nice seeing a 13b reliably making that kind of power on the top end. Great drag setup! Me personally, it needs more low to mid range.

 

We recently switched out the exhaust housing to help out with that! But now we are going with a different setup and more power.

 

How long before the new results? You guys stick in a BW 9180?

 

We are tearing into it within the next week or so!

 

What boost was the 612whp and 7+?

 

More power? Jesus Christ how much power you want? 900whp? lol

 

I would have to look back at the logs. I think the 612 was at 25psi and the 705 was 31 or 32psi.


No specific number we are shooting for! Just more power

 

semi PP and more boost is the way to go for more power at this point, it'll probably help spool that big turbo quicker as well!

 

Small update with the car as of now the engine is out and we are starting from scratch with a new engine. The owner now wants to break 900whp with the car! We are hoping to have it finished up within the next month or so and will post our results. Stay tuned
