Say, Greddy kit owners, has anyone tried their kit with a Koyo radiator (or some other race radiator), Greddy catch can, and some oil cooler and Greddy oil pan? Just wondering if tuning the Greddy kit would be easier with some nice efficiency parts. :D

Not sure if it would help, but just wondering what the results would be.

catch can.... nope no need.... just run a big hose away....
oil cooler... YES!!!...
pan... nope... just check the oil more often.

radiator YES!!!

the result: your car can take a bigger punishment from you ...
no power gain...

So adding this kind of stuff would prolong engine life?

Never thought of that. Then again, never had a bolt on turbo either.

Just bought the PWR radiator from TURBO8. I will be putting it in next week, along with my boost controller (hopefully upping boost to a consistent/holding 8 psi across the board, with a 10 psi "race" program). I'll let you know.

crimson-rain

Man, you're really puttin in some work tuning your turbo. What's your avg. hp + torque goal? Won't you run into a fuel issue at 10psi though? Just wondering.

Fanman

Definitely getting larger injectors from RC Engineering (need to find out whether our injectors are low or high resistance units).

I would be more than happy with an everyday drivable 260-270 whp.

LOL, the mod list in your signature is consistently longer than your actual posts :D

Tell me about it. It started out as a fun car to play with, now it is an obsession.

When I got past 9 PSI my car starts pinging. No matter if i am rich or lean it just pinges. We need to find how to play with timing a little bit. IMO bigger injectors just won't do. I am only at 70% duty in my injectors, have a long way to go before upgrading them.

Fanman

Well, I'll be sure to tell my mechanic to look out for that for sure. I'll let you know what we can (if anything) do.

BrazilianRX8

the problem is the emanage....
try using something else... works wonders for me
i am using unichip http://www.unichip.us

RX8PR

To run the RX8 with more than 10 psi you would need tocontrol the timing of the car.................

How is the unichip programed, laptop? Can you change the timing and fuel settings(injector sizes, base fuel map) Also what is the base map they are using for the RX-8 or is there a base map for RX-8 stock from Unichip? It is very hard to tune if they do not provide a base map to know where and how much fuel to add and timing to remove.

Thanks

BrazilianRX8

what i know is that unichip controls timing, injection, pressure, nos injection, speedometer, bla bla bla.....
all that on a 200rpm base and trottle position.

i dont realy know were to buy it on the us... since i am in brazil!
but i have one on my car with an extra injector ... and this week i am puting it to 10psi hoping to get very very close to 300whp

right now i am running 255 to the weels over greddys standard psi

BrazilianRX8

and yes... it is a laptop programed...

i dont think it is that hard...
we did it on a days job, including the extra injector...so... not hard

So how do you know what the timing was stock as I am very interested to know this? I am not saying it is hard for you to do but for some it is a shot in the dark.

BrazilianRX8

the real key to set the car up is to have a dyno... without it you are in the dark.
what we do here is to have the "program" set to zero, then we set the dyno to lock the rpm on the car for, lets say... 3000rpm. and at that rpm we start moving the variables and see what the car is gaining or loosing for each variable... timing, fuel, pressure....of course for trottle position just as well.
then you move up to 4000rpm do the same thing, and so on
after all of that you go for a full dyno run, meaning from 1000rpm to 9500rpm
and see the graph
then you move into the 'dips' to fix it...
you are all done

it takes like 2 to 3 hours top.

Well that is much easier then tuning my 7. I would have popped countless motors on the dyno when I was tuning. I am glad it is working out for you.

Thanks

BrazilianRX8

so far so good, i can put you in touch with my mechanic over here in brazil if you want...
he can get you more tips on it.

You know that you can only run injectors at 80-85% max duty time right?

PUR NRG

Nope. I did not know that. Care to explain why?
