guess my dyno number?

[GrayZ]

:dontknow: so .. i thought i would start a thread.
headers, top end ported, corsa exhaust, hi flo cats
what kinda numbers is she gonna turn??

Franks doesnt get to guess.... rofl

[Jagdpanzer]

427 at the wheels

[-=Jeff=-]

412

[Zr1 Destroyer]

When you say top end is ported you mean the heads are ported also!? If so.......I'd say 415rwhp!!!

[rhipsher]

Probably alot. But I'll still smoke it on my naturally aspirated unicycle Ha:mrgreen:Ha:mrgreen:!

[XfireZ51]

412


????? With ported heads.

[Jeffvette]

500 crank.

[Paul Workman]

I'm gonna say 390-400 rwhp, if the heads are not also ported; 425± rwhp if they are also ported. Guess we'll find out tomorrow. See ya then!

Paul.

[XfireZ51]

500 crank.

:iamwithst

[jonszr1]

my guess 416

[bobbyhi]

my guess is 394.

[GOLDCYLON]

422 to the rear

[GrayZ]

When you say top end is ported you mean the heads are ported also!? If so.......I'd say 415rwhp!!!

yes, heads are ported also.

[flyin ryan]

What make of Dyno you going on...any idea?

[cvette]

What is the current displacement??? You didn't go head deep and stop there did you Keith?

[PhillipsLT5]

410 rwhp with stock flywheel

[Bob G]

413 to the tire

[Locobob]

410rwhp... Marc told me he was focusing on mid range torque in order to move your substantial midsection :wink:

[Paul Workman]

410 rwhp with stock flywheel

Ah! Good catch (on the flywheel factor). But, someday we-ins iz gonna need a thread to kick 'round that so oft spoken of flywheel power differential (as seen on a dyno:rolleyes:). I recon it will go along the lines of energy to spool it (the flywheel) up to speed in a dyno setting vs. reality of the road/track.;)

P.

[GrayZ]

fidanza flywheel included, i forgot that, part.



Hey Loco.... :bootyshak

[Aurora40]

Then I'd say 432whp.

[HIZNHRZ]

With Mark constantly making incremental improvements and with the fidanza flywheel, I’d say 435; maybe 1 or 2 more.

[bobbyhi]

With the new infor I have to change mine to 418 at the wheels......

[Bob G]

With The Flywheel I will change my # to 428

Keith,

Are your reflexes up to the increase in power? :cheers:

I believe it can be factored out with eddy-current type dynomometers where the acceleration rate can be controlled. On a dynojet, you are rolling a big drum of known weight. The faster you can accelerate it, the more wheel torque you are making. Presumably the inertial weight of the flywheel is not trivial when compared to the weight of the drum, thus you can see it make a difference. Presumably if the drum weighed, say, a million pounds, you would not see much of a difference.

On the road, I don't know how you'd exactly quantify the difference. I guess you'd need to compute up everything like the wheels/tires, driveshafts, weight of the car, etc. I think it's safe to say that as you upshift, it would make less and less of a difference, as the rate of acceleration would be less and less, thus the flywheels resistance to it would matter less and less.

Personally I think it would have to make a crapload of power for me to put up with one. I've driven Ron's car with one, and man is that sucker noisey when stopped! Of course it accelerated like crazy compared to mine, but I suspect that's the 390ci more than the flywheel.

I tend to think of the Z as more of a GT car. It's a bit heavy and softly sprung, with tall gears and tons of top end. The rattly interior belies that a bit, but it can be a pretty enjoyable everyday and cruising car that also happens to be wicked fast. I kind of prefer it that way.

Keith, you'll have to let us know how you like the flywheel. I've no doubt you will like the extra horsepower from the 500 package, so no need to tell us about that... :)

[RICKYRJ1]

435 :thumbsup:

[-=Jeff=-]

I saw the dyno Sheet, I will let Keith post the #s

[WB9MCW]

427

[jonszr1]

ok so who is the winning guesser ????????

[Locobob]

Don't leave us hanging Moudy... how'd she do?

[tomtom72]

Don't leave us hanging Moudy... how'd she do?

:happy1:

[Aurora40]

Oh, I've another question. Did you get new headers? I seem to recall you used to have the smaller primary tubed Watsons. Did you change them to 2" ones? Or did you leave them? Or is my recollection wrong?

Also, make with the number! :)

[GrayZ]

Mark and i are very happy with the results. He explained that leaving the cats on the car would take away around 6 horsepower.

the car dyno'd 499 to the crank, 424 rwhp.

the removal of the old stock engine paint and the polishing, makes the engine look like a diamond in a jewel box.

car pulls all the way through the power band.

Mark explained, a new porting technique allowed him to acquire approx.
8 more ponies than he expected. :wave:

[cvette]

Not bad!!!!!!!! Looks pretty damn good too man! Congrats!

[Zr1 Destroyer]

I was 9 rwhp off......do I still get a free beer!?!? Good numbers!!!!

[FU]

Those are H/P T/Q numbers for a good 368 with stock cams. Nice job :thumbsup:

[WB9MCW]

I AM THE WINNER RIGHT ??? 427 GUESS ONLY 3 HP OFF RIGHT?

YEPPERS

SO NEXT TIME I AM IN ST LOUIS I GET TO COME BY THE JOINT AND GET THE GOOD ZR-1 TABLE AND HAVE A STEAK DINNER AND DARK QUALITY BEER RIGHT?

PLUS DANCING GIRLS TOO!!!


I CAN HARDLY WAIT --:thumbsup:YEPPERS I WIN !!!!:jawdrop::happy1:

[Jeffvette]

I AM THE WINNER RIGHT ??? 427 GUESS ONLY 3 HP OFF RIGHT?





Just like the Price is Right, you went over, and lose.

[Locobob]

The horsepower is wrong... bitch :mrgreen:

The prize is that girl in Jeff's avatar gives you a bust in the mouth :mrgreen:

rumor is that girl in Jeff's avatar is Keith's bartender :mrgreen:

[PhillipsLT5]

flywheel? stock or fidanza

[Pete]

flywheel? stock or fidanza


Fidanza.

[jonszr1]

i see some high 11sec ets in your future

[QB93Z]

Great numbers Keith! It sound good too.

It was fun following you back to St Louis.

Well I guessed 422 to the rear looks likes I was off by two :mrgreen:

[GrayZ]

Rumor has it you're "OFF" by a ton more than two.....:sign10: :mrgreen:

Hey im playing with a full deck.... 52 Jokers :razz:

[WB9MCW]

Just like the Price is Right, you went over, and lose.



Damn Jeff you are right --

After review I see that you were only 1 HP high

So I guess we both got screwed

Looks like the Spaceman is the winner being only off by two under!!!

Hope he enjoys the steak, beer and the dancing bar tender :thumbsup:

[Aurora40]

So??? How do you like it so far Keith?
