Volvo Dyno Day Results?

[stevehayes01]

So I did not make it down to the Volvo Dyno day due to bringing my wife home from the hospital friday night but I wanted to see how it went and see if some of you guys would post up your dyno results?

I know some SAAB folks stopped by but did not Dyno but I hope that we can do a joint Swede Dyno in the future!!

SCVCOA dyno run for baseline on my '91 745Ti, factory M46, 210+k miles and counting:


Original Garrett T25, never been modified/tweeked/boosted/etc.
Original engine/tranny, down to the original clutch, even.
Original T-cam, which I doubt has even been reshimmed.
Original cat, and despite being a 49-state car, it's way more than clean enough to pass CA emissions.
OEM Volvo plugs, approx. 47k miles ago. Spark plugs wires definitely original ... which is making me wonder whether the cap/rotor has actually been replaced that same 47k miles ago in which the PO said he had a full tune up done. Whatever, though.
No resonator or muffler. PO had a shop do it, and they didn't do too good of a job. That's gone, and in place from the cat-back, $4 Autozone straight pipe to a $4 elbow to a $12 new stock over-axle pipe to another $4 straight pipe and a $5 chrome tip.
Synthetic Mobil 1 10w30, last changed at 206k.
Regular Mann paper air filter, changed at 180k miles.
Regular ATF type F in the tranny, Regular 80w-90 in the rear.
Running on Unocal 91 octane, last filled up 2 weeks ago in Buttonwillow, CA.
Tires are Kumho HP4 716 in 215/60/16, mounted on Ronal R25 16" x 7.5", for a combination weighing about 42lbs./each. This oversized tire corrects the speedometer, which is otherwise off on stock sized tires.


With all that said, the dyno run today yielded:


142.2hp ... factor in a typical (theoretical) 15% drivetrain loss on a manual, and I'm getting 167.3 hp @ 4800 rpm. The Volvo manual puts the turbo at 162hp @ 4800 rpm.
177.9 ft.lbs ... factored, 209.3 ft.lbs. @ 3700 rpm. Manual has it at 195 ft.lbs @ 3450 rpm.


So it's nice to know that after 14 years, it's all still performing at just a little above stock level, which I suppose may be attributed to the exhaust system (and lack thereof). Essentially, I look at it being at just about stock level, which is reassuring in this sense ...

Such said, the graph (http://www.powerpuff.net/volvo/powerpuff_run.jpg) shows a disturbing period of leaning between 2450 and 3250 rpm. Obviously, it's abnormal, and it can't be good. So after all this, what could be possible culprit(s)?

That's the number one thing I will be taking care of first. Soon after, I will be doing a "zero mile" maintenance, with a new clutch/plate/etc., the iPd turbo cam, new fuel pump, port the exhaust manifold, 3-in. from turbo all the way back, and other "basic and essential" performance enhancements.

-- Kane ... though still kept to safe limits. I don't intend to break my car(s)! :-P

PS: Some pics taken from between when I got there and when I left (which was a before everyone was done, as I had other plans too) to be up in a few days or less.

PPS: Learn to spell, Steve. (see subject) :p

Vovlo!!

[stevehayes01]

Vovlo!!
Yeah Yeah Yeah!! I fixed it!!

[stevehayes01]

PWRPUFF --- thats pretty cool that it still is doing better than factory!!

brought by pontiac down for a baseline.

about 200hp
about 305tq

Not bad for a 30 year old stock motor. I had it "freshened up" but it's still the original internals.

Now I can get the new radiator and put on the headers, 3inch exhaust, and manifold :tup:

What kind of Pontiac??

74 Lemans GT Sport Coupe

[stevehayes01]

Very cool! I just sold my 68 Buick Lesabre that on its last dyno put down 335HP and 415lbs. TQ. Gotta love the old classics.:p

74 Lemans GT Sport Coupe

Really? Thats an odd choice for most PMD fans. I had a 74 Grand Am we built with a 455, th400 and a 3.23 LSD. Ugly as SIN fun to drive though.

I used to build first gen firebirds all the time though, check it out www.pbase.com/dkauer744

It's basically the same as the GTO w/some minor changes and the parts are a little cheaper. It's still got the 455 and the th400. It's different and most people have never seen one.

Oh I know. You just know how snobby GTO owners are... 'oh a lemans thats.. nice"

I always liked them. The 74 was kind of a neat car. Theres a damn 72 GTO sitting in a yard near my shop, has been for YEARS. I always leave a note once in a while ;)

I dont miss my POCI days (Sacramento Chapter president a couple times) though... Im having fun doing bricks.

It's funny how GTO owners turn their nose up at Lemans owners and everyone turned there nose up at us lowly Buick owners even though we all shared the same engines and trannies. :confused:

No matter what you'll always have your snobs and elitists. :tdown: That's why I don't hate ALL imports, every now and again I'll see a car that was well done and good work deserves respect.

I saw a kid in a restored GREMLIN on the 57 by the 210. I couldn't believe it, the thing looked brand new! I thought that took a lot of effort and confidence to rock the gremlin.

[Doug242ti]

Yep. Thats pretty much how I feel... hell its why Im doing volvos right now. I like oddball things :D
