Hey guys,

So I plan on getting some AC 160cc single shots here pretty soon (and getting a reburn for them). Also, I have a RR HPX to install and will order a RR FRX to install at the same time. I am curious as to what kind of HP I am making currently, and what I will be making with new set ups.

Current Set up.)

E99 Turbo
6637 Air Intake System (w/enclosure & zoodad)
4" Turbo Back Exhaust
DP Tuner (F5 - See tunes in sig)
AB code - 130cc Split shot injectors

Set up 1.)

E99 Turbo (current turbo)
6637 Air Intake System (w/enclosure & zoodad)
4" Turbo Back Exhaust
DP Tuner (F5 - See tunes in sig)
AC Injectors (160cc)
FRx
HPx

Set up 2.)

Same as set up 1 + Termi T500 HPOP

Set up 3.)

Convert to 99.5+ turbo set up
Turbonetics Turbo (pushing close to 30 psi)
6637 Air Intake System (w/enclosure & zoodad)
4" Turbo Back Exhaust
DP Tuner (F5 - See tunes in sig)
AC Injectors (160cc)
FRx
HPx

Set up 4.)

Same as set up 3 + Termi T500 HPOP





Your input would be greatly appreciated.

 

Bryce sounds like like a good plan and I too wonder what your hp#'s will be. I have a E99 too and I am thinking about something like your set up #1.
I hope as long as you are replacing the injectors you are going to replace the injector cups due to the problems others have had with early 99 injector cup sealant.
Well let's see what the experts think.

 

Thanks Ed.

Hmmmm.. Now that you mention it, I do remember hearing something about that. Good point! Cheers

Another one for the list. Preventative measures are always good.

Holy Cow! The cup removal tool requires a $200.00 deposit!?

And the cup retaining compound is $40.00!?

Anyone have a removal tool I could use and send back when the time comes for the install?

 

Got my guesses in.

 

Thanks for the input Cody. But you dont think that a turbo pushing 30 psi as opposed to 20 will make any hp gain?

 

Just my .02

 

Thanks Cody but I see you would say set up #1 and #3 as same hp rating what would think the torque would be on stock e99, #1 & #3 ?

 

Thanks for the pennies Joey. So stage 1's and a turbo pushing around 30 psi put them anywhere from 350-400 huh? good to know.

I would like to dyno my truck somewhere after I install the AC's. Even on the E99 turbo. Anybody know of one near Ellensburg, WA?

 

You'll see that setups 1, 2, and 3 are all the same. It's a function of maximum fuel rate, nothing more. Regardless of how much unnecessary expense is put into the build ("crossovers", etc.), the ultimate power output of the engine is based almost exclusively on the amount of fuel that you can get into the cylinder per combustion event.

No. Boost is over-rated as it is nothing more than a measurement of restriction unless you can get the exhaust out of the engine. The more force (backpressure) that is required of the turbine side to make the compressor side do it's thing, the less and less of a return on your "boost investment" that you will be making. Boost means very little when you're talking about stock or stock-ish parts as all you're doing at that point is adding more heat to the intake air. Guess what...all of you people who bash Gale Banks for his beliefs need to take a lesson from what he preaches.

 

It depends on how much the injectors are hurting for high pressure oil.

The torque rise on low injection pressure (high pulse width) is incredible and will usually be higher than a similar run that is able to maintain pressure.

Really, the power difference between an E99 and 99.5-01 truck is so minimal that if you drove one blindfolded, you'd never know the difference. People make it out to be such a big deal and in reality, the biggest problem with the early build trucks is buying brake and suspension parts.

 

Woa, nobody is bashing anybody on this thread.

And I understand that the boost pressure doesn't mean that much but volume of air does. A bigger turbo housing and higher boost pressures means that you are pushing more volume, and that means more power.

I am by no means a turbo guru, but that is my understanding.

 

Thanks for your input and I just thought that the e99 with the smaller turbo and 130 injectors would make a big differents. So it is nice to know it isn't that much differents.

 

If you're simply increasing your manifold pressure, you are not increasing volume through the engine. That's where the misunderstanding comes in. Now, if you take the steps to reduce drive pressure (by "opening up" the turbine side), THEN you can see some increases in power.......

However, your maximum boost pressure will likely DECREASE.

More boost does not equal more power in this case...it just makes the gauge more fun to watch and makes for bragging rights.

Case in point:
Stock '01 with mild tuning: 26 PSI. 285 RWHP.
Change to Turbonetics Journal Bearing and larger A/R turbine housing; all else the same (same dyno, two hours later): 21 PSI. 298 RWHP

Now, the results were nearly the same for maximum power tuning at 308/310 (no recollection of boost pressures)....but the engine pulled A LOT harder in the 2500 + RPM range with the less restrictive turbine housing. Boost was down with the aftermarket turbo and the drive pressure was down by a little over 1/3.

 

I made some edits in case you missed them.

 

I wish there were air volume gauges in CFM. That would be helpful
