first dyno on fresh rebuild / non-seq - untuned
threw the car up on the dyno today over at A.R.T. in Sarasota, FL:
the fd made 252 horses / 200 torque on a super hot & humid day.
10psi of boost and the car is still 100% untuned, just using the power fc base map. also the timing is slightly off...
tomorrow we will be tuning for 15psi of boost (hopefully the turbos can make it!)
current mods:
+ Large Street Porting (Intake & Exhaust)
+ 3mm Mazda Apex Seals
+ Stock Twin-Turbos Modified for "Rich Man's" Full Non-Sequential
+ Apexi Power FC & Commander
+ Jet-Hot Coated 3" Straight-Through Downpipe
+ Rx7store.net Resonated Midpipe
+ HKS Carbon Fiber / Titanium Cat-Back
+ ACT Xtreme Duty Street/Strip Clutch Kit
+ SR Motorsports 9.5lb Aluminum Flywheel
+ Fluidyne Over-Sized Competition Radiator
+ M2 AST Coolant Expansion Tank Bypass Adapter
+ M2 Carbon Fiber Airbox w/ Dual K&N Filters
+ Modded Efini "Y" Pipe & Crossover Pipe
+ Blitz Dual SBC Spec-R Dual-Solenoid Boost Controller
+ Magnacore Spark Plug Cables
+ Silver GReddy-Style Alternator & Water Pump Pulley Kit
...and the rest of the mods aren't power-adders.

understandable, but 15psi and tuning with the stock ic. Big NO NO! It probably will not be just a few pulls. Cars usually stay on the dyno for a few hours to get a nice smooth tune out of them. Running the stock ic is going to be bad. Plus when you upgrade your intercooler, you will probably want to retune your car anyways. put it on before you go jumping into things.

Gota post a video if you do the pull on 15psi i want to see one of these intercoolers pop never seen it before.
Power still looks a little low for with out a tune guess tune will make a huge difference i have around the same mods but more fuel and open exhaust and shooting for over 300rwhp at around 14psi on a good tune once i get mine back from IRP.

here's a question for you guys...
is there anyway to brace the intercooler end-tanks? perhaps some huge hose clamps around the stock IC might help keep those plastic end tanks on until the new V-mount is in there! haha
the name of the shop is called A.R.T.
they are located on ashton ct., which is kind of off clark road, about 1/2 way between us41 & i75.
my neighbor owns the shop, pm me if you want his contact info.
haha i would like to see that too!

Power/tq seems about right to me. You have a real pretty engine bay, 'cept that stock IC Crank it up to 15 psi and get it tuned, you should be well over 300 whp and that's more than enough to get you in trouble on the street 
What kind of dyno is it? If it's a dynojet, please ask the operator for the run files (you can put them on a CD or a USB pen drive) and email them to me, I'm spending some time studying dyno data and it helps to have the raw files. Good luck and keep that silver car CLEAN!!

Wow, didn't know there was a dyno there. When did the shop get it, i saw the orignal post of it opening up, but no mention of a dyno. What kind is it? I'll have to come visit. I'm in sarasota alot. I ran 14 lbs of boost on the stock intercooler for 3 years no problems, except blowing up the coupler. But i do agree if it has to be on the dyno for a long period of time, that might cause problems. Do you know if the tuner has experience with tuning 500- 600 hp FD's, and tuninmg with methanol injection setups? I'll stop by and ask, just wondering if you know?

yeah yeah, keep in mind, i said it made 252hp completely un-tuned. everything is pretty much just plug-n-play right now. with tuning and boost, we're aiming for 300+ numbers, even with the crappy stock IC.

they got it a few months ago, but there was something wrong with the first one they received. the company sent them another one and it works great now.
they definitely have experience with high horsepower cars. i just saw a 660hp 300z roll out of the shop two days ago. they're also doing a twin-turbo viper now. the owner has a 500+ hp 300z and his wife has a very nice single-turbo FD.
like i said, PM me if you need the owner's contact info.
we're going to push for 15psi tomorrow so i'll share results!

Am I mistaken or doesnt the Power FC instructions tell you that the base map is only good for light driving to your tuner to get it tuned. Why in the world would you dyno the car with the base map? If you have to much money in your pocket I can always use an extra buck or two.

I think its a good idea, I don't see as much information as I would want too on how well tuning a car can effect HP levels. Also, it can say alot about the shop that did it to take a car that gets 252 hp to 302 hp with tuning, it would be a good shop! Besides, I'm at the point I think you have to have extra money to throw around just to own a FD!

how come everyone is bringing out that he needs a larger intercooler....and not directing him to the fact that he has no fuel system or ignition mods(besides plugs wires, which do pretty much nothing).
the stock ignition can only handle about 12psi. any more, then you start to get break-up
also, the stock fuel system can only withstand around 12psi till the fuel pump is obsolete. your injectors will also be running at a very high duty cycle.

He should get an ignition but injector duty cycles being high is not a threat. I was reading a good post somewhere on this saying the stock fuel system can handle 350-400hp in good hands and yes the fuel pump can handle the stock injectors. The intercooler does need to be changed because they are know to pop at high boost levels.
Heres that post on duty cycles https://www.rx7club.com/showpost.php...43&postcount=7
Good luck with the dyno want to see over 300rwhp gives me hope for mine.

lol guys, it's not like we're just going to throw the car on the dyno and crank up the boost to 'see what happens'
obviously we're going to step up slowly over several pulls, tuning for proper a/f, etc at each level.
yes, i am also looking to piece together a new fuel system as well - we wanted to test the limits of the stock system before doing so though.

I'm running secondary injectors in all 4 with a street port and large stock mount. Made 310 HP at 10 PSI and that was with a weak primary ignition. You should be a little higher on your HP.

But i am positive the stock fuel pump can handle over 12psi. Quoted from turborx7.com"2. I've heard the stock pump "isn't good for XX psi of turbo boost." Is this true?
No. The stock fuel pump is adequate as long as the rest of the fuel system remains stock. The stock fuel pump doesn't flow enough once larger or additional injectors are added, or the fuel pressure is raised intentionally (with an aftermarket pressure regulator).
My tests have shown the stock fuel pump can maintain pressure for up to 15psi of boost. It can probably flow enough for beyond 15psi, but the fuel injectors will normally go static before the fuel pump runs out of flow (and drops fuel pressure). Likewise, the fuel injectors or fuel pressure will need to be raised to maintain the proper a/f ratio before the actual pump limits are found.
The bottom line is with a stock fuel system the injectors will be maxxed out before the fuel pump becomes inadequate."
Now for injectors they can support up to 360rwhp at 100% duty. At 85% they can go up to around 305rwhp. As stated on turborx7.com good site has alot of info and recommend you take a look at it 4cn air.

I can see a popped motor on this one.. Hope you have an upgraed fuel and an ignition amplifier for that much boost. Colder plugs.. Why tune and do a bigger intercooler? Going to need to tune it again! Get a catback as well. Be a bit more patient and do it right!! Take it from someone who's been there done that! G

we're on pull #9. still smoothing out the A/F. haven't pushed more than 10psi.
get a catback? read the mod list or look at the photos
be more patient? we've done 9 pulls and haven't touched the boost controller...how is that not patient?
i really feel like people on this forum just TRY to make ******* comments.
i never said we were going to throw the car on the dyno and crank it up to 15psi. i said we were going to step everything up...
