Not what I expected, but the car does make me smile every time I drive it.

I had two people guess 185, but @ROOTWORKS did it first. I've got a video that I';ll get uploaded to youtube and post it here

If I read it correctly this is being tested on a chassis dyno measuring rear wheel hp.

I looked pretty quickly at your build thread (cool thread) lots of pretty pictures but I think I missed details on cams, compression ratio, etc.

Then there is all the dyno variability (water brake, eddy current, inertia dyno).

I'm going to take 251 HP at engine minus driveline losses = 213 HP at rear wheels. May the God of Speed bless my guess.

Posted by: Mark Henry May 1 2021, 09:49 AM

Do you have a link to the build spec? You could be anywhere from 180 to 240hp .

My 3.0, 40 Webers, twin plug, MSD with Mahle RSR pistons and web 120/104 cams, I'm guessing 250-280HP.
It will be interesting to see if there's any difference with the SDS EFI system I'll be installing.

Please share a video of the dyno pulls if you can.

I'll say 205 with a tail wind

Posted by: Jett May 3 2021, 08:53 PM

I came to the same initial conclusion and then added 15 HP for the matching shroud + air cleaner blue paint.

Posted by: Jonathan Livesay May 3 2021, 09:30 PM

I say 224, simply hoping to sneak in between two more educated guesses.

I have no idea what I'm in for. Do I drive the car? Hoping someone else does so I can video. Do I pull the air filters off? I was told they do 3 pulls.

Posted by: Chris914n6 May 11 2021, 01:19 AM

They drive. You can video if they are OK with it. Leave filters on.

Bring a gear ratio chart just in case they don't have it on file.

Ask to have the fuel ratio included to see if jetting is off.

Tape your redline # near the tach if it's not what's on the tach.

Wait . . . . I need to recheck today's temperature, barometric pressure, and humidity and readjust my guess.


Nevermind. I'm holding firm at orginal estimate.

Posted by: Root_Werks May 11 2021, 04:17 PM

Kinda fun, will do this with my 914 when I get it all back together.

Posted by: 76-914 May 11 2021, 07:18 PM

Why didn't he run it up to 7 grand? Do you have a rev limiter?

Posted by: Superhawk996 May 11 2021, 07:33 PM

3.0L RoW motor was only 204HP DIN so you're right there after adding 15% back in for driveline loss.

Couldn't tell if you hot rodded it or not so you definately gave us a fun time guessing. Very cool!

As you state, it's all about the smile it puts on your face. And, to top that off, your car looks amazing!

It doesn't take much to make these cars feel fast

A lot of people think 200whp in a 914 is slow until they actually feel it.....

Congrats!

Posted by: Superhawk996 May 12 2021, 06:05 AM

All about weight to power ratio. 200HP in a 2000 lb car puts you at 10:1. A very respectable number. Especially in a mid-70's vintage car.

Ferrari Testarossa is around 9.7:1

70's / 80's supercars like an early Lambo were around 8:1 or a smidge lower.

Late 90's sport bikes 4:1 or lower

Koenigsegg One:1 is the mythical 1:1

Posted by: Root_Werks May 12 2021, 08:19 AM

Woo Hoo! I guessed it!



Totally doing something like this for mine.

Too fun!

Posted by: MM1 May 12 2021, 06:58 PM

@PanelBilly- can you please explain how you arrived at these numbers ?

Perhaps I missed something but it looks like the dyno says 176 hp and you say that the correct guess was 185hp (at the crank?) - so that would mean a parasitic loss of only approx. 5% ( if the 176hp number is real wheel horsepower ) - correct ?

Posted by: PanelBilly May 12 2021, 07:45 PM

185 was the closest guess to 176. Wish it was a way bigger number. I read that the clutch and transmission can reduce the engine HP by 15%, but I don't have a way to really measure that. I just used the number the shop gave me

Posted by: abes914 May 12 2021, 09:21 PM

Thanks for the videos. Gorgeous car by the way and the car sound great
