Getting an ECU, now what's the HP
I ask you guys what my HP and Torque would be since I am going to the dyno in a few weeks. But I ask you with the mods I have now. I have an ECU lined up and will probably get that soon. I know someone selling a G-force. Those are pretty worthy right? Anyway, what numbers should I be looking for now at 12 lbs and at 14 lbs (can 14 lbs. be run on the stock IC for a short time). The only thing that I won't have that is truely needed is an upgraded IC which will follow in the not so distant future.

With your mods:
12 psi ~ 255-260 RWHP
14 psi ~ 275-280 RWHP
Reprogrammed ecu doesn't change the power, it just spits out more fuel to prevent running lean and blowing the engine. A programmable ecu such as the PFC can be tuned to optimize the A/F ratio to extract the maximum power.
Even with 12 psi, you are pushing it on the stock ecu. @ 14 psi you may only get one chance, but hey, it's your car.

Firstly!
12 - 14PSI on std IC, dont do it!
Have you a DP, MP AND CAT BACK. Oh forgot, intake?
@ 14psi your fuelling is maxed out so look @ the safe way first!
1. ecu
2. dp
3. cat back
4. mp
5. IC
6. INTAKE
7. Boost no more than 12psi
8. over 12psi
9. fuel pump
10. bigger injectors (1200cc) secondarys
then max @ 14 psi on stock twins, any more, say bye bye to turbos or engine. Go high flow twins or better, GO SINGLE!
Good luck
Regards...

The stock IC has a very small total cooling surface. Running a boost higher than 10 psi causes the turbos to generate more heat at the outlet. The stock IC is marginal at cooling the air at 10 psi, it is basically ineffective at 12 and 14. (Also, if you are on the dyno, there is no air flow throught the IC. Being inside the engine bay, the intercooler now become interheater) Some shops hook up a fan to blow air, but it is very difficult to produce the air flow equivalent to a speed of 70+ mph.
to your engine. Like Trex said, it's your car. :shrug:

Man, this board confuses me sometimes. Some days I will see people with the same mods as me and ECU that are running 12-14 psi and say they are doing fine. Then the next day I got people telling me I am going to blow the motor.

I have the gforce ( im selling it too!!) and i can say it makes more seat of the pants hp then the Pettt and the stock one ( dah!) It feels tons more powerful.. No idea on my boost level though....

We all want more power for our pound or buck(UK)
But I think you know now what is best for your car and your bank balance! I think you would be shitting yourself running what YOU thought was (or might be) safe!
Forget some of the sheep that do it on the cheap! Get a Ic first and PFC or keep the boost to 10.5psi
Like Arnie said "DONT PUSH ME"
Good luck!

I've tried to help ya by saying 10.5 psi is the safe limit on a STOCK IC. CAN YOU READ
It sounds like you want to *** ya motor! Then go ahead run 14psi like a muppet!
LOL
Come back in 4 weeks of hard driving and tell us how u got on!
Later!!!

Dude don't get so pissed off. I wasn't saying I was going to do anything. Everything that I have said is hypothetical and everything that I have said I have heard from others on the Forum saying that they have done it. Also I already said that I was going to keep the boost level at 12 psi. 14 psi was another hypothetical situation. I am listening to what you are saying , I am also listening to what others are saying and trying to make the best of it. There is really no need to get frustrated and start throwing personal attacks.

The upgraded ECU will provide enough fuel, but people are just saying there are other things to consider besides the ECU for running at increased boost levels.
I think you would be safe up to 12 PSI, but I don't think 14 PSI would be a good idea at all.

Just don't *** up! The best thing you can do is ask!
I'm the same! Im just about safe with mod upgrades
Power FC
PETTIT POWER INTAKE
PFSIC
3MM HURLEY RACE TIPS

NEED BIGGER SECONDARYS/FUEL PUMP!
OH YES SINGLE TURBO!
I'm on the limit at 12psi! I being serious!
Good Luck!

I understand. I have heard that 12 psi is about the max boost for a consistent duty cycle (80-85%). I have heard boost levels up in the 14-15 psi range pretty much maxes the injector (100%) and pretty much just destroying them (overwork). About right?
After the ECU, I will concentrate on the IC, too bad those are a small fortune

Keep it under 12psi until IC Time!
Then you'll be better off!

an ecu usually ( altough i think gforce and jet are the only ones doing it besides knightsport) is advance timing. Timing = power while your not detonating...
thats where most of the power comes from!
