My Dad took my R1 to the dyno yesterday with mixed results. Initially I was disappointed, but as I looked at the big picture I realized there is still a lot of potential there.

Corrected SAE rwhp 376
Corrected SAE rwt 303

This was with a peak boost on the commander of 1.07 kg/cm^2 (~15.2 psi); not sure about inj duty. I'm going to have my dad email me the dyno chart to get all the info. The ambient temps were 94 degrees, intake air temps in the mid 50s, and the damn place didn't even put a fan in front of the car. My good friend Nick has dynoed at this place a few times and always seemed to make lower numbers than expected, so I am definitely going to try another shop. I've surmised that all of the above deflated the numbers a decent amount, corrected numbers or not.

My dad was the one in the driver's seat during the dyno runs (there were only 2, basically identical) and he said that 4th gear seemed to take quite a bit longer to wind out then when he and steve were on the highway and making repeated runs for tuning---he checked the profec b because he honestly thought it was on low boost.

I feel that given better circumstances and 17 psi, the car should make right around 400 to the ground as advertised. It's odd, b/c it made 368 at KDR about a year and a half ago on the stockers, and she feels much, much stronger now---like a different car with over 100 horsepower more, really. Of course, that dyno was also in January in Pennsylvania.

Next step is to get a 3 bar map sensor and have Steve fine tune her some more, along with some minor airflow enhancements like intake hard pipes and double throttle deletion. This will all of course come after I come home from my little vacation .

take it easy guys--

 

the FD

it's not a car, it's a life

even when you are in Iraq!

just kiddin, Rich....keep us posted

after talking with some other people, I think the KKK or GT40 single is the way to go

how is the lag compared to the stockers or a small single?

 

what afr?

is the 400 rwhp advertised assuming a ported motor?

oh and btw...376 rwhp is one fast FD..congrats

 

That's what I'm getting on my stocks. Do you think it's worth it to upgrade to these turbos? What advantage do these have over the stocks? Last longer maybe? I'm getting those numbers on stock turbos and non ported motor. I know when I rode in Stephen's car, it felt like a monster, but my car was weak back then.

 

WE MUST RACE!!!!!!!!!!!


for the first round on the dyno you are doing fine...youll break four hundred with some minor tweaking Im sure.

so...get that kicking *** for america self home and lets hit the streets!

Yes. As I said above, I have dynoed at 368 on the stockers, and there is no comparison. It's like a different car. Stephen trapped 125 mph with his setup, which is very similar to mine. I'd like to find the stock turbo'd FD that could hang with mine, esp through 3rd and 4th gear.

Actually, the next time you're on the highway, have a bud with a stopwatch handy and time yourself from 40 mph in 2nd gear to the verrrrry top of 4th, 140 mph. If you can beat my time on stock turbos and stock motor, I'll buy you a case of beer.

Btw, do you have a dyno sheet, drag times, etc?

 

The lag is barely noticeable compared to the stock twins, and my seq setup was always very responsive. I don't miss the stock setup at all, and I surprise myself when I say that.....

 

Thanks . After all the hype, I was expecting more, but 94 degrees and no air into the intake prolly shot me in the foot.

I'll have to see the dyno sheet, but high 10s, low 11s, some in the high 11s.

 

 

i dont mean this in a negative way...but i wasnt. With 17-18 psi you will be right around 400 rwhp

 

Oh, I'm going to kick some *** alright.....yours, blasting up highway 35 from Austin to Fort Worth .

Yeah, I think given better condition, 1 or 2 psi more boost, and Steve tweaking her, 400 is easily reachable. Dynoing in June/July ain't too smart anyway.....

 

Well, that 376 was only at 15 psi. According to Bryan these suckers aren't in their efficiency range until 17 psi. My main interest is in the car being fast as ****--numbers are all well and good (I am a math major, hehe) but not the be all and end all. If I can trap around 125 (doh! another number) in the quarter, I'll be a happy camper .

Edit: Yeah, I think the ported motor is a bit of a necessity to crack the 400 barrier (JD's 7 notwithstanding ).

 

we shall see my friend...we shall see....and so will everyone else when we video it.

I figured I can stand outside the car at launch to get some good shots...then when you take off tires smoking Ill jump in and catch up to film me passing you.

lol

seriously though...it should be a very good race.

As said before... It's not like at those numbers your car is slow or anything!

 

Must.....have.......more........POWER

 

Yeah that is pretty darn fast. Anyway I think you could easily reach 400rwhp. Like you said go to a different dyno and get it tuned. Yeah Stephen said he could trap faster with a drag redials. Also he still has the stock rear end and he granny shifted too to pull 125mph. Anyway if he put a KAZZ rear end and slicks. Dang he could hit over 127mph. Good Luck Goodfella.

 

Didn't you do that 368 rwhp with a Hi Flow Cat too???

I'm a bit suprised as well you didn't dyno more but I've had some inconsistent readings too before.

My best was 357 w/ stockers at 14.2psi with a HF cat. I'm hoping to do better once it gets back as I have some small improvements as well as a stronger streetport now.

I'd love to see what you put out at 17psi but the case for a MP doesn't seem that pursuasive in your case.

David

 

I wouldn't sweat the numbers, Rich. I'm sure you'll easily trap in the 120s.

So, when are you going to bring that beast to the Bay Area so I can see the results of the BNR/Gotham Racing/Steve Kan combo? Think of it as west coast advertising....

 

i know of a car with stock twins that can hang with you

cough*boostn7*cough

congrats 367 rwhp is good!

 

hes not done tuning vosko you silly rabbit.

boostns obviously a great tuner, his car is a beast and a freak of nature. tis why he is the only guy in the history of the fd who pulled it off. rich had pushed his stockers pretty much as far as they would go reliably on his vehicle....and thus the upgrade.

hell...boostn can hang with and beat your car all the way to the upper upper rpms* laggy *cough t78 *cough.



just kiddin...lol...sorry...i had to.

The 94 deg air was a BIG factor. I dont even bother getting on my car when its that hot out, it just feels "slow" compared to cooler temps. I think it shorted you at least 20hp.

 

i know boostn7 personally. trust me i yell at him too for going faster than me with stock turbos. he just keeps telling me...... i am just beginning and he is almost maxed out....... i can't wait for the weekend. we'll see what happens at SUMMER SLAM

 

I'm a kinda new to the FD, but not to rotaries and tubocharging. Isn't running with no air to the radiator and intercooler motor suicide. I guess the sessions must be very short in duration or else the heat would kill the motor.

I've never done a dyno run....looking forward to it after I get my Kan special port and BNR's.

 

Awesome numbers Goodfellas...I'm sure once you get YOUR hands on it, it'll be even better. Keep us posted, you brighten my day with those numbers.

 

Pour in some 116, crank it to 20psi and report back soldier
