Let's play, "Predict the HP Game" (take 2) ---- this time with a 3.6L ;-)
 

OK folks...

Earlier this year we played "Let's Play - Predict the HP Game!".

CamGrinder won by a hair, and took home $60.00 in cold hard cash (cashiers check actually).

Now it's time to play again. Call it Round 2 if you will....

The car's the same, but the engine is different.

Here's the details:


.................................................. ........................

THE PRIZE:

$75.00 US

.................................................. ........................

ENGINE SPECS:

964 3.6L twin plug long block - just rebuilt.

Larger intake valves (equiv to 993)

Web Cam "993 Sport" grind

Patric MotorSports 1.75" headers

M&K 2 in, 2 out muffler

PMO 50mm carbs with 41mm venturis, tall stacks, ITG filters.

Electromotive XDi crank fire ignition

1982 911SC, stock 915 gearing

.................................................. ........................

OFFICIAL CONTEST RULES:

A) The dyno will be performed on the same DynoJet 225x dyno as the previous "Predict the HP Game" contest.

B) Power correction: SAE Corrected at the wheels

C) Closest Guess (decimals count) over or under

D) If multiple people guess the exact same number and that guess is the winning guess, then the prize will be on a pro rata basis (shared)

E) Guess is for PEAK HP number

F) Dyno test to be done in 4th gear

G) You may revise your guess as often as desired.

However, you must revise your original guess on your original post.

Only one (1) guess post per person (again... which may be revised at will prior to the contest end).

H) Contest End:

Two (2) days prior to the dyno test, I will announce the contest end.

One (1) day prior to the dyno test, I will post the "closing post".

The "closing post" shall constitute the end of the contest.

Editing or altering your HP guess subsequent to the "closing post" will result in your vote not counting, you cannot win, and the most you can possibly accomplish would be nothing more than pounding sand.

:-)

Let's see those predictions....

285.5 whp.

Cheers

293.5 RWHP

284.75 rwhp

Re: Let's play, "Predict the HP Game" (take 2) ---- this time with a 3.6L ;-)
 

I actually won the earlier prediction, just for arguments sake. :)

I guessed 200 whp, which is what Tony is telling everyone is 3.0L SC motor made in various threads, so how come I didn't win?

Good luck with the new engine, I hope it makes the power you are seeking.:)

Sorry... in the actual contest, it was won by a "hair" as I said previously.

To me it made no difference as I paid out the winnings fair and square.

I tried to be fair and honest and offered a time period for any disputes to be settled. This is the reason why I laid out the rules in detail for this contest. Additionally, I feel like the rules spell out very clearly how the contest will be decided, trying to leave no room for judgement calls in any direction.

In my posts, not related to the contest, I cliam 200RWHP. In reality it made 199.xxx RWHP :-) I gosta rounds up!

But my claims and my contests are two diffent things. One I can fudge a little and one I cannot.

So kick CamGrinders butt and one-up him!

249.05 at the wheels:)

294.6 HP

276 rwhp

SAE-corrected at wheels? Does it mean that it will be corrected for drivetrain loss?

298.7 hp is my best guess.

289hp at the wheels

288.3257 ;)

Corrected - 301.00

286.4 rwhp

324

is this on street gas? 91 or 93 oct?

Those valves- they will be equivilant to the '95 993 valves, or the '96+?
How long are you going to spend tuning it?
This is on CA 91?

2 ways to calculate:

1st:
An older Jerry Woods 3.6L C2 with his cam and 46 webbers made 319.3 on the engine dyno. I'll give you +13hp for the bigger valves and 50mm PMOs, then -4 for the new cr@p 91 octane, so est 328.3 crank. My estimate for crank to wheels power conversion from Jerry's dyno to dynojet =293.7 rwhp.

2nd:
My 993 Vram made 280.5 rwhp on a dynojet with a 3.8 RS cam. +8 for your solid lifer cam, +8 for the PMOs, -4 for cr@p gas. =292.5 rwhp.

Average them:

293.1 rwhp is my official guess.

This is fun.

315.2 hp.

303HP

petevb, 911teeo, and all others...


The valve sizes are equal to the +96

This contest will be run on 91 octane pump gas (southern california 91 pump gas that is...if you can even call it gas).

I will be tuning the carbs and the ignition map on the dyno for at least a good 1/2 day+


TonyG

Where's camgrinder.....

I know you're watching. What's it gonna be?


TonyG

288.8 HP

camgrinder

No hydraulic. Full mechanical.

I will run the dyno pulls 500 rpms past the peak HP readings. The top end is good (supposedly) for 8,000 rpms.



Gonna be interesting.......

TonyG

271.0hp at the rear wheels.
-Chris

thats ez,, 3.5L bumped a lil =..... 341.5

my guess 300

At the wheels :confused:

That would be pretty amazing... 400hp from a 2 valves 3.6L aircooled N/A engine....

Not even the 3.8 RSR reached 111HP/liter ....

262.7.....but hoping you have more!

Lets see....1 L will put out a ez 60 hp times 3.5 some wheres around 210 plus additives (cam and ect good for some more.....dont know all you tricks).....but on the conservative you have to be 300 so all those guesses are taken and I needs a number here !!!....that's my formula and I am sticken to it.

You have two posts, both containing a "guess". Neither will count.

You have to only have 1 post that contains your guess.

Also, the power is SAE Corrected at the wheels (not engine HP).


TonyG

302.66

If you allow that they get to 100Hp per litre then you get 360 at the flywheel allow for a %loss through the drive train and assuming the correct ramp rate is used then I would say

272.72 RWHP

Michael

NoNoNO.....I was sort of explaining my too high of number..my 1 st one stands....thanks,,,,,,,OK??

afterburn 549

No problem...

Just make sure you're clear on your posts.

Additionally, you can change your guess at any time before I "call" the end of the contest (see rules).


TonyG

Oh, in that case, my guess is 268 hp.

267.567588549 :D

277.96

278.3 @ the wheels

282.3

271.9
