thanks yea im lookin forwaed to putting the new exhaust on

 

hmmm, may be needing to switch to the utec soon. i like the knock functions that come with the utec. if greddy got the eu to read and set (real time) timing, i feel it would easily rival the utec. wouldn't think it too be too hard for greddy to do.

 

A larger diameter exhuast will result in less backpressure, less thermal load on the motor, and more power at a given boost level. Depending on the level of restriction, and the boost pressure used, we've seen anywhere from 20whp to 60whp improvements.

Essentially, the motor has to overcome significantly less pumping losses in order to spin the turbine. A lot of folks have the misconception that a turbo produces "free" power, unlike an SC that has to spin a pulley with crank power. But a turbo doesnt produce free power, as the engine still has to overcome the turbine sitting in the exhuast stream, and the back pressure it needs to overcome. It is much more effficient than an SC, however.

 

So, how difficult is the UTEC install, and can I order it pre-loaded with maps, based on MY mods? What's it take to tune it, a Laptop and a dyno, or a "special" interface like with the UniChip? Just looking down the road.......

 

Install takes about 10 minutes,base maps will be only for getting to the Dyno and getting tuned.Any tuner can tune it without software or special cables..

 

If you install the UTEC, the map sensor, and the Tuner, you are looking at about 1.5-2.0hours of labor.

You will need a laptop, and a dyno to tune an FI car, but no special software or cables are required.

 

Sharif some questions.......

1. my car with Turbonetics Idles from 14.7-15.5 is that bad???? under boost its fine tho..

2. if you get a UTEC is it better to swipe the ECU to stock or leave it????

3. will there be a full blown UTEC package anytime soon???

TY

 

1) 14.7-15.5 is a good idle AF...nothing to worry about.

2) You can leave the TN reflash in place. Once the UTEC kicks in, the stock ECU is completely out of the picture, so it will make no difference.

3) What do you mean by full blown UTEC package?

 

I was reading somewhere that on a dragster it it takes 100's of hp to run the SC. I think it said that it would take a big V8 to run it.

 

As a general rule, an typical cent SC is about 65% efficient, and a typical turbo charger is about 85-90% efficient. Dont take my numbers at face value, as I use them simply to point out that a turbo charger is significantly more effecient than an SC, but its still not FREE power.

 

+1 for the UTEC.. I had it in my WRX and thinking of running it in my Legacy GT..

 

Did the car get tunded today?

 

The cars were tuned on Tues and Friday of last week. Once the 3 inch exhuast is installed, I can retune again. The PE kit was putting down much more power at pretty low boost...I was impressed!

 

Keep us informed on the PE kit results, I have not seen many PE kits and am curious of their potential..I know Performance motorsports ran their PE kit to 10.3 on the 1/4 mile..Must have been over 600whp at that point.

 

Yeah, depending on things like head flow, cams, and the type of fuel used, 600whp should be doable. Very few people have pushed the PE kit as far as the Greddy and APS kits yet, so there isnt as much prior history to refer to.

 

Shawn from SGP told me they can set exact timing with the EU when I was talking to him about my car the other day. Mark told me that as well.

 

I downloaded the latest version 1.09, and the "Actual timing" menu is still deactivated. Hmmmm.....

 

Well maybe I misunderstood him, but I told Mark and Shawn that I wanted to switch to the UTEC because you can set the actual timing instead of plus or minus like the EU, and they told me they can set the timing with the EU.

 

I will call Greddy right now.

 

i was impressed too but it looks like we might have to push that retune back a bit. had the car back for bout 4 hours and looks like one of the turbos may have gotten messed up. not sure yet if thats what the problem is but thats what david thinks. ill let you know when i find out more i think they start workin on it tomorrow to find out exactly what happened .
