I put a Powerdyne on V6 Beretta about two years ago but just recently found this forum. The Powerdyne kit was purchased off of Ebay for a 350 Chevy truck and is controlled by F.A.S.T. programmable ECUHere is an below and a link to the development the last year or so. I have not dynoed lately nor have I been to the track but with over 230whp and 260wtrq in a 2700 lbs. chasis makes for a great daily driver. I have about 65K miles on the mild engine rebuild and about 30K miles under boost.

Look forward to sharing experiences of boost and tuning.

Skip the update if you want details on chasing motorcycles. The and newly updated trans. And clutch are running fine with about 4000 miles since installed. I do have a slow oil leak and am pretty sure it is the rear main seal leaking and an open iginition wire somewhere that when driving through the heaviest rains it causes the tack to drop intermittently. I did have a problem with the ign. Control module that I just replaced in Feb. cutting the ign. Anything above 3500 RPMS. A new ign module solved that but when very wet it acts up again. That one has got me confused…but it runs. With the Beretta being down about 2 months this past summer I really like driving it, so much I don’t want to break it by going to the drag strip or road course as I have done in the past. I guess I’ll save it for the next BerettaFest. 

The race of all races…racing motorcycles. I was on my way to a buddy’s in Akron when a sport bike came flying up behind me off an onramp and then slowed, rolled past as we got into 3-lane cement divided highway where he laid down on his gas tank and took off again. I was approaching my exit but decided to pursue the bike following behind him up to over 100 MPH for a half a mile or so he slowed and sat up. I think he might have caught me in his mirror and twisted his neck around to make sure I was not the police. The road opened and he was accelerating to speed again until traffic slowed him down. Then impaitiently split traffic and a took off again.

So I decided to turn around as I was 5 minutes from the time I told my buddy I was arrive and as I exited the motorcylist was at the bottom of the exit and was doing the same thing I was. This time he saw me following him but I was a couple hundred feet behind and when on the return entrance ramp got a good jump on him and was probably doing 100 MPH by the bottom when he merged out onto the highway. He pulled away strongly to about 110-120 MPH but stopped pulling away to well over 130+(speedo numbers stop at 120). He got off of the throttle and looked in his review mirror there I was(this time with my headlights on so he could better see me through his vibrating mirrors).

When traffic cleared he took off again but this time a Audi A4 cut off the open lane. I was thinking get this A4 1.8t out of the way. The A4 took off pretty fast but already had mommentum on him as he moved to lane three and noticed it was a B6 S4. The bike was in lane one and the S4 moved to lane two as we slowed to about 80-90 when the bike came up behind up in typical ***** flyby fashion. I was behind the S4 and hit the go-pedal before the bike past us on the left. It took a little time to reel the S4 in but caught a little draft off the S4 and was surprised to see the driver’s look of anguish as I passed him like he was standing still. He was never a threat in catching me, nor the bike as we went back up to 120+ again when the bike got out of it in traffic again. The S4 stayed back this time.

The motorcyclist then popped a wheelie next to me and I put it in 4th to get around him for the next exit as I passed my buddy’s exit for the 2nd time. The bike was no challenge on one wheel.  I gave him thumbs up when he passed and he returned it.

I looked up some C&D articles on the S4 and trap speeds are 102-103 MPH in the quarter mile. I rolled right past him(about 100 MPH) and he never posed a threat in matching my speed, twice. I have also had one try to follow me a few months ago when I shifted down to 4th gear and left him. I guess my trap speed in 5th gear would be around 105 –106 MPH.. This is backed by messing with a LS1 Camaro a few months ago with a very loud exhaust. We were pretty even from 70-90 MPH. Yeah, 5th gear… I never shifted down the whole time racing the bike or the S4. With a 4th gear run it would definitely have been a different story in getting around the S4. The bike is just plain fast up to 120ish where the lack of torque when shifting to higher gears and poor aerodynamics at higher speeds slow it’s acceleration down to match an almost 300hp, 2700 lbs. car. So my theory is ending ¼ mile at peak horsepower around 5000-5300 RPMs and a nice sub 2.0 60ft short time should yield 106-108 MPH trap speeds.

This is all on engine that is not designed for boost but with careful, conservative tuning can be quite fun as a daily driver. I pulled the spark plugs this past weekend and noticed quite a bit of carbon build up around the thread area leading up to the ground electrode. So I advanced the timing from 25 to 27 degrees. During the first high speed run with the bike I blew most of the carbon out leaving a nice black plum on the highway. I took a look at two front plugs today and there was still carbon build up but you could tell which side was facing the piston as there was just a thin layer of carbon. Sparkplugs are a good eye into the engine to see what is going on.

Keep the shining side up!

Sounds awesome! I've gotta go eat lunch, but I want to read this all up when I get back Maybe we'll have to meet up at the track sometime

did you make the bracket that the s/c is on?

 

Dang man, that is nice. 210/238? Very nice! I nailed 222/291 on my turbo 3.1

So when can we meet up for a race? Do you have any 1/4 miles times?

 

ladies and gentelmen

The bracket is just a piece of 1/2" aluminum mounted where the alternator bracket mounts.

Doward, your weight to power ratio is on par with the Neon SRT-4 which runs about 14 seconds flat. Haven't seen your dyno yet but would like too. Your probably reaching peak power before 5K RPMs. I peak close to 5500 RPM. Higher than the first dyno run in the BerettaNet thread as I have not dynoed recently. Your power band may peak higher but mine will be broader. I'd bet you a few colds ones on that.

What was you AF ratio through the operating range?

C'mon and show us your dyno graphs! :^)

Norm

 

1st...

 

*drum roll*

 

That is about what I thought.

Nice torque curve though! You should be in the low 13s in the quarter mile with the proper suspension setup.

Not bad tuning with a FPR. Tuning with a wide band O2 could keep you a little closer to 12:1.

I am just not a fan of turbos for everyday driving as they are so elastic in their delivery. My new project LS6 is get a Procharger Centrifigal blower.

Norm

 

I did not see your quoted first graph but the second. According to the title it was your 2nd(.002) not the first run. I ran three(3) runs and the hp maybe varied by 5 or so.

I'd love to smoke you in FLA heat. :^)

Norm

 

LOL.. Actually, it's a high of 67º today. With my FMIC, I'll happily race ya

Yeah, the first I posted was actually the 2nd run, lol!

 

Were you able to record intake temps during your dyno runs?

Well it is in secure hands. Not sure what I find but the SC or programmable ECU might be of interest since we share the same engines.

There is nothing "elastic" about turbos, and power delivery...
They take a little research and math to be done correctly. Take this froma person that has dealt with them for a number of years. My last one was a T4E/T3. Had boost at 2600, full output by 3100 and continued to make power through 8000K+.

I would take a turbo powered car over a S/C'd one anyday. They are way beyond power gained / parasitic power loss of a S/C.
They are simply not as easy as a S/C bolt on.
Hell most the time, even if the car was originally equiped with one(turbocharger), you should expect to spend nearly 3-5 months in research, fabrication and tuning. There are just not as many variables or options in S/C's are there are in turbo's...

 

I guess it would depend on displacement. I had a '00 Saab 9-5 Aero with electronically controlled wastegate. The electrically controlled waste gate was supposed to make a more linear power delivery. It had Nordic Stage III tune making over 300hp/330trq and would smoke Corvettes from 100 MPH on up and ran door-to-door with a late model M5 from 100-130 MPH.

But off boost to boost and in daily driving or autocross the power/torque was not there. I drove my buddy's Comptech S2000 with Vortec blower, granted it did everything in the upper range, it was allot of fun ringing it out to 9K RPMs.

I recently drove a Subaru Legacy GT with the 2.5l boxer motor and it reminded me of the Saab. And the S4 twin turbo with KO4s had insane mid-range but thanks to AWD when the turbos spooled up in the middle of a turn it maintain its intented direction of travel. That is one reason you don't see turbos in 2-wheel drive, in anything other than straight line, full throttle racing.

The belt driven blower, centrifugal or twin screw rather than roots, give a larger displacement feel with it's inelastic nature building boost throughout the RPM range.

Norm

 

I see my dyno graphs are still up... nothing 'linear' about that delivery. Press gass, and it's right there, lol

 

with gas prices the way they are now a days
what are your average mpg

 

I was running about 27mpg before the turbo, 24 after, 20 if I'm always in boost (LOL), and now around 26 in 'normal' driving.

This is like 80% city, btw

 

and hes still getting better mpg then me.

Hurry up with my chip doward

 

Looks like the block is cracked. Should I get another and start over?

http://www.beretta.net/board/ib3/iko...r=1;&#entry183

Norm

 

yeah that looks pretty cracked to me

 

Since I am parting out my project for another I can pass on my 3.1 V6 goodies to the community:

and thos parts would fit on our engines? I always thought the fwd intake manifold wouldnt't fit...
