Re: powerdyne setup

Ill have to check aeroforce gauge this out for my self, it gets too damn hot here in Houston.

I like them , I run 2 Aeroforce gauges and their outstanding.

Re: powerdyne setup

Not to thread jack, but is there anything that I could read to gain some more knowledge on PD's on our cars? Im building a motor and will be running a PD, as some of you already know.

Well PD on the most part is a street level entry SC. The belt limits it to 10psi, but 928 people has improved it's cfm from 850 to 1200-1300 and they've been able to safely run this blower at 15psi.

PD is good to our stock engines and it's even better with a cam set up. Grayman has an excellent write up on this. Just search his site here.

If you plan on running more than 10psi then you might as well go Turbo.

Re: powerdyne setup

Do to the internal belt on the PD , I would say 6-7 PSI would be max if you want your belt to stay intact and have a DD. Thing about 928 is they rebuild their superchargers after every race, so thats how they get around not breakiing parts. I had mine done from 928 when I had my PD and it was the worst money I ever spent. After looking at what they did I could of done it for $300 instead of dishing out $1200.

Re: powerdyne setup

Thats why I picked up the PD, as Im new to FI set ups. Car will be running an XP cam, thanks guys.

Re: powerdyne setup

thanks now~ here is in winter so it will be ok~ i think but in summer i will get intercooler

:)

Re: powerdyne setup

With stock engine running it like you do should be fine. But might look at seeing if your getting any knock in the hotter months.

Re: powerdyne setup

Woojong... holy cow. I remember you from way way back then. You still have your Firebird that you converted to a TA body?

FMU is good if you only have stock injectors and they are usually good for up to 9-10psi of boost.

If you have 42 injectors and HP Tuner you don't need FMU anymore.

Good to see you are still around too brother.

holy cow. how could you remember me.. thanks...and good advice

i will tell you what my situation is..

when i got powerdyne first i set TRC-1 actually mechanic set it but he couldnt set it exactly


so the engine blow 3times... because of nocking.. so i was so sick of that setting with stock moter


so i challenged below's set up


8.5:1 forged internal, pd 9psi, intercooler, ls-1 injectors, texas- data pcm tuning
, FMU, MAFtranslator, CIA header, Magnaflow exhaust, 1.8rockerarm slp, 255 welbro
,ngk tr-6, msd coil and wires

eventhough i had texas -data pcm tuning i had to set FMU and MAF translator because of A/F ratio

my FMU is sard's one which i can use any fuel pressure so i got 10:1 A/F on top rpm

with above mods.. but at that time.. the crank main bearing had some noise it was rubbed

but i ignored it so i could drive supercharging bird but the power was not enough to me

so i tried to make boost more from p/d... so i had many problem with bearings...as you know.. hehet anyway

after 4years later the main bearing was broken and the moter was blow

hmm at that time i made up my mined i go stock engine with pd setup

because the forged internal C/R was so low for my boost.. so the power was not enough

for me..

so i figured out if i use p/d with the stock moter it will more useful

so i tried to set p/d with used moter but that moter didnt have enough oil pressure

1 month later it blowed again..... my god~~~ :( so bad thing for me..

this time so i got good used moter now

actually i was so sure just stock moter with just FMU and 6psi without no pcm tuning

makes 230-40 rwh power

but yet i didnt have experience about that setting..

eventhough i sure but on the other hand i blowed my engine many times.. so i was so

worried. it might happen again.

:) but a few days ago i set it again with stock pully and stock p/d impeller

with mainthings(plug pcv,6psi,ngk tr6)

at that time i didnt set boost gauge but i could the boost working and car act like it had supercharger....

so far i feel good actually in these days i dont have time to drive bird... just i drove

it once after setting hehet~ anyway

from now... i have to make plan next setting..

now~

my car mods is

6psi, FMU, slp 1.8rocker, CIA headers, Magaflow 3" exhaust, msd ignition coil and wires,
ngk tr-6, and now my car has T-5 trans mission.. i swaped it but still i have A4 stock pcm
so my cluster's speed is not exact.

and i just have p/d small pully for 9psi, 928 motersports bullet impeller, 42.5 lucas injectors? maybe.. and ls-1 injectors that is all i have

and now im planning buy 255 welbro fuel pump and in january get hptuner...

hmm

2.8bird~~~~ you said to me stock injectors handle 9-10psi.....

so i think next mod

just add 928 impeller with stock pully and 255walbro pump..

how do you think? just that mod?

or just add 928 impeller without 255walbro pump

will it be ok? 9-10psi with stock injectors, stock fuel pump

in this case i think i have to set FMU more exactly..


hmm which setup will be good for me?

im worried if stock fuel pump can make enough fuel pressure or not

and how big horse power can i make from 9-10psi with my setup?

hehet~ long story with poor english..... isnt it?

i dont have good english skill.. plz.. understand me.. hehet thanks...again..

Re: powerdyne setup

It also depends on the type of gas there is in Korea. Do you guys have high octane fuel? 92 and above is the most ideal and you don't to retard your timing too much.

If I remember in 2003 you said that gas in Korea is not that good and ideal to boosted cars.

you so smart guy :) yes here octane is not so good. but we have also high octane fuel..for

premium... but it is expensive... almost 1.9$ for 1 liter

anyway nomally 89-91 and premium is 92over i think...

Re: powerdyne setup

Do you have anything to monitor KR?

sorry i cant understand KR.... is it intake airs's temperature guage?

[woojong]

Re: powerdyne setup

Im using 36lb gtp injectors with no FMU. I would recommend a wideband 02 and fuel pressure gauges to keep an eye on your motor.

i dont have wideband 02 but i have fuel defi guage... when the moter rpm is idle... the fuel

pressure is 3.1kg without p/d

but now i set it 4.0kg when the moter rpm is idle with p/d charging..

Re: powerdyne setup

Sounds like you need to pull timing , and need a wideband with Hptuners to tune it properly , a mail order tune is worthless when it comes to FI.

Re: powerdyne setup

What is wideband?

[ssms5411]

Re: powerdyne setup

What is wideband?

Wideband is a O2 sensor that is 5 wire so it monitors your Air/Fuel ratio so you know if it is running rich or lean to optimize your fuel. Running lean will blow your motor quick esp. if your running FI/ supercharger. I have a PLX-300 wideband that I have been using for over 10 years now. There about $300 or around there and mounts before the CAT.

Re: powerdyne setup

KR= knock retard= bad

Re: powerdyne setup

after tuning for my turbo, i think, fuel management systems are a horrible idea for boosted applications. because you will still be running way to much timing. so you might as well get hptuners and take care of everything.
