First RX8 in Puerto Rico with Greddy- 273HP
 

(First, sorry for any syntax error, my first language it's Spanish)

We finish our installation two weeks ago.
My mechanic tell me that run the car for at least 400 miles
before a dyno run............................

We put the car on the dyno yesterday. The car makes 273HP in 4th gear and near 260HP on 3rd gear. (on the attached dyno we have 2 runs one in 3th and 4th gear)

I make a few 1/4 mile run's with my g-tech and the best times are between
13.90 - 14.20 sec.
Right now my big problem it's traction in first gear the car it's lo loose
and you waste time before the car has good traction.

Next step is to install a boost controller...........we need to have constant
7 psi boost. Between runs on the dyno we note that at full throttle the car don't
Maintain the 7 psi.

The car has the Greddy kit but also has pulleys, ACT clutch, Flywheel, Hi flow Cat, resonator, 10.5 spark plugs and other modifications.
I'm happy because I was expecting near 240 HP, when I buy the car the first dyno was 175 HP.

I agree with others that this is another car........

My tuner removes the front sticker of the emanage and manually set the last to
screws and we get 4 HP more and the car it's running richer......
To tune this emanage manually it's not easy, it's easier with a computer.........

NOW WE NEED THE PASSWORD FOR THE EMANAGE!

If some one have the password and can give it to me
I really appreciate it...........

The tuner it's and expert working with the Greddy emanage on other
cars and it's ready to make some changes to see if we can make more HP.

If any one has questions, please let me know...............

and again, sorry for any syntax errors!

Manuel

Manuel- very good info and no syntax errors. I'd love to bring my car down to P.R. and have your tuner install Greddy and tune car. WOW 273 H.P. That GREAT

Thanks,

We are ready to try to get more HP.............just need the emanage password.

My mechanic it's the owner and mechanic of the local racing beat dealer.
They have a lot of experience with rotary engines.................

wow thats awesome how much did you spend total?

I already spend near 9K.......................(includes wheels, carbon fiber, etc.)
It's a lot,
but I just love rotaries


Manuel

nice turbo, i wish i had one.plus nice engine bay aluminum caps

Boricua Power

Dale Pa'bajo, llega a los 300hp

RX8Power

Thanks ,Rx8MAN04X
The car also has a lot of carbon fiber on the interior.......................


RX8power,
Thanks, I think that you know how good are the local guys with rotaries..........
To get the 273HP they already make some tricks..........

our next step it's increase HP.............. 300HP? maybe........I wish

with the boost controller (already ordered) and with stable fuel supply
we think we can get a few more HP.

My big concern it's traction, one's we find some more HP we are going to
change the differential. We need to down the 1/4 mile times.

Manuel

Manuel, what was your dyno after your other mods but before the Greddy? I'm assuming you did another dyno after your initial mods. Thanks.

RX8PR,

I'm trying to work on my car here with couple of guys who got, RX-7's, Starlets, 1200 and GLC's, right now I got 10K available, well kind off, I'm trying to buy a house so if I don't have to pay for any down payment, everything it's going under the hood.

RX8Power

It was 181HP and on that time I feel so bad, I was thinking on a bigger number.............
But on that time it's was all plug & play no tuning..........
with the turbo installation the mechanic spend some time tuning...............

manuel

RX8power,

I wish that first you buy your house..........then find some $$$ to put under the hood.


Manuel

Oh yeah, that's #1 priority, but like I said, any money left goes to my #2 priority, my car.

Nos vemos loco y suerte

Rx8Power

Wait, you got 273 rwhp with the Greddy kit? That is pretty damn impressive!

nice

how are you preventing detonation running that lean?

Last I heard - gtech wasnt very accurate. I think one member on here evencalled it a fun toy. And even if his figures are correct - I seriously doubt his Rx8 would only be running the quarter in 13.9 w/273 whp. I think that number is bhp. Reason being is that a stock 350z (which has about 240whp) runs the quarter mile around the same time as his 8.

he did mentioned that he has bad wheel hop in first, so 13.9 on a bad launch don't account for much. Measure flywheel hp is pretty tough compared to whp from what i've heard, his original figures of 175hp was base on whp i don't see why 273 would be any different.

Yes the gtech are not accurate readings but I just used to get some estimsated 1/4 mile times. This morning on the highway I make 14.07 on one run and 14.15 on the other one
always with traction problems on first gear

to prevent denotation we use 10.5 spark plugs we also tuned the emanage manually
to have the car runing reacher at high rpm's this helps a lot with detonations

The 273HP are at the wheel in 4th gear, at 3 gear we have less HP near 260............
the torque is 235 in 3 gear
We make a lot of dyno runs and the car makes all the time between 268-275 HP range

Remember it's not only the greddy kit, we tuned the emanage manually to get some HP
we also had pulleys, ACT cluth, Flywheel, cat back, hi, flow cat, resonator.
we're using only the greddy MAF sensor we disconnect the factory one, with the factory
one we have serious problems at idle..............we have a CEL but the car is runing without problems.


Manuel

get some bigger rear tires.

Where'd you get the high-flow cat?

Manuel;

I am also from PR and I would like to get the racing beat exhaust, where is the racing beat dealer in PR? By the way, where do you test your car in Carolina or Salinas? I would like to see it. Thanks.

Those ultra-cold spark plugs allow him to run reallyu lean for a turbo. That can give you a bit more horsepower at the wheels. The trade off is they foul VERY easily and you will have to replace them every 1500-2000 miles.

I thought we were defying the laws of physics when he gets over 100hps gain from only 7psi :P

you have to remember his other mods are going to factor into his gains as well.

Cretinx,

Good idea on bigger tires, but my interest it's on a bigger diferential this would help
to lower 1/4 times.

rotorpr,

The local racing beat it's in Bayamon "mecanica el psiquiatra"
they have a dyno and all the runs are in their computer.....
I mention that all the 1/4 miles I do it with a gtech
Yes, he has the racing beat cat back on stock........
I have the borla because it's was the first on the market.
I live on Manati if you wan't to see the car and get a ride
on the car just send me and email


philodox,

Thank you for your comment, I asked my mechanic about the spark plugs
and he say's it's depend on the use of your car but
he recommend to check them every 4 months and at least clean them.
I really don't use the car every day.........
This sparks really help to prevent detonation, using the factory one's
with the greddy kit it's to risk for the engine.

philodox,
I read your thread's and I know that you already have some information on the emanage
password but I don't find it............please let me know.........my tuner it's ready
to put the hans on it. If he can improve HP I would post on the forum.


thanks to every one,

Manuel

Quentix,

the hi flow cat it's from random technologies........you can search the web to find some
dealers that sale their products. I buy it from Canzomer.

Manuel

Well, if you look at his AFR, it's teetering around 13.5 which by all rights should detonate like a mofo.. that's where the extra cool spark plugs come into play.. you can run a bit leaner without worrying about detonation.

When the car it's hot we get some 12.4 AFR, when the car is more cool we see higher AFR.
I think that the computer knows that and recompensate the AFR.

Before changing the sparks we make a couple of pass with the factory sparks and the car makes 268-270 HP in 4 gear.
The 10.5 sparks are not giving us higher HP, it's to prevent detonations.

Manuel,

That is great!

I heard rumors about a couple of turbo RX8 in PR, but that was about it.

Give them a call (Mecanica el Psiquiatra) and talk to Eggie. Their phone number is 787-780-6398, and Galdy's phone number (Eggie's first son, and the dyno tuner) is 787-787-7876; they are good and reliable people.

we need more members like him on this forum! he opened up a new thread, said he has turbo, and has the pics and dyno sheet to prove it...hehehe

Where's the oil catch can??

Knonfs,


Galdy is the mechanic of my RX8....................

I know something about others RX-8 Turbo in Puerto Rico,
Also there is a 3 rotor RX8 proyect, but I don't know when they're
goin to finish.........................
The other day I was on "mecanica el psiquiatra" and a guy that was
tuning and RX-7 1993 (420 HP at the wheel!) tell me about
an RX8 turbo that makes 11.5 sec on the 1/4 mile on the Carolina speedway
if it true? I don't know........

Saludos!! Yo vivi 20 años en el area de Bayamon/Toa Alta, ahora tengo casa en Vega Alta pero solo visito una que otra vez al año pq estoy viviendo y trabajando en Michigan.

Yo tuve alla en PR un RX7 del 84 y otro del 86, ahora tengo uno del 93 twin-turbo aca en Michigan y le estoy haciendo par de cosas pero lentamente.... Mi daily driver es una Protege5

Mano felicidades con el 8, tengo planes de comprar uno pronto jejeje!! :D

Thanks,

It's amazing how many puerto rican's are using this forum..............
The love and passion for the rotaries it's in our blood.


Good look with your 93, Rx-7................

Manuel

Oye, mi pana!!! Otro Boriqua orgulloso aqui!!

Naviles,

you're the previous owner of 9 different rotaries.......................
amazing!

Boricuas en la Luna....

Ahh....si....tu sabe...los rotores estan en mi sangre.....us Puerto Ricans are crazy for rotaries...haha

Yeah--when I was down there I saw like 3 RX8s for every 350Z. Probably more that I missed cause I was too busy breakin my neck to look at the women.

Is that why the "long lost son" of Gaylord Focker on Meet the Fockers was working on a nice red FC? Anyone notice that in the movie? I think his mom was Puerto Rican too.

...ok, back to topic :D

OK guys

On the next step we're goin to install a boost controller and remove the high flow cat and the resonator..........we're goin to use a straight pipe connected to the borla cat back.....

The big problem to generate big HP gains using the emanage that came with the greddy kit it's that we can't control ignition timing................... but we need to continue our work
with this limitation. Probably in the future greddy can provide that for the RX8.
Of course that we're open to use other type of computers........

Manuel

Here is food for thought for you people who want to post 1/4 mile times

THE RX8 DOES MID TO HIGH FOURTEENS SO ANY 1/4 TIMES LESS THAN 14SECS WILL BE CONSIDERED REASONABLE ANY OVER 14 OR IN THE 14SEC RANGE WILL BE CONSIDERED FULL OF COW SH..

that's good news. i spend over 10k already on my car. most on exterior and suspension. i want to wait for a better turbo or some thing is better than the one right now :)

good results! I wouldn't have thought GReddy left that much more power (tuning) in the kit...I was sure Philodox had an exhaust too - a 30hp difference though? wow! :)

dmp but it still pulls 14s so really not any quicker than stock.
make it 12-13sec than we can talk

We have no idea what his car 'pulls'.
e/t's are a function of driver anyway, not of the car. Those were GTech runs, btw. They are invalid except if he had done before/after comparisons.

Those A/F's are really lean and would not do that on a daily basis. Even with colder plugs its not going to help.

Just to bring light to the subject. Yesterday I met RX8PR in Manati, PR. I went with my car RX8 2005 6M stock and RX8PR brought his car (Greedy Turbo, pulleys,clutch ........ and a lot of other stuff everybody should know by now). I drove the car and it is amazing the difference, the quick response of the car on the low gears seems like another car, specially when I went back home in my stock RX8. The issue with the ET on the 1/4 mile, really is related to traction and not to power believe me. Currently he got 19 inches wheels and the tires cannot handle the power. He will be working on the traction issue, currently he is on bussines travel but he should be back next week. RX8PR, THANKS A LOT FOR THE RIDE AND THE EXPERIENCE.
