That'show I feel. The dyno is a tool. The real numbers are at the track.

If it's 15 percent, which certainly makes sense, that's 596 flywheel hp... or 1.72 hp per cubic inch. Not too many people can say they have 1.72 hp per cubic inch. Even at 575 it's 1.66 hp per cubic inch. Very few people can make that claim on a n/a motor especially a daily driver.

Darths driveline is very efficient, I would estimate his losses
At closer to 12% VS 15.

I disagree....

I think 15% in this case is spot on

He's got gears and a power robbing rear end (both those items hurt efficiency). Trans and clutch is certainly good....bet he is about 90 more at the flywheel than the rear wheels. Puts him in the 600 realm for sure which makes sense cause my Vette that dyno'ed 475-480 back in 04' had a really efficient driveline with the C5 small ring gear, light clutch, light wheels, carbon fiber propshaft, etc. and I lost exactly 75 from flywheel to RWHP.

Note I made 550 at the crank with that combo which pales in comparison to this build which has much better heads, much better intake, more compression, larger TB, larger headers, more cam and a solid vs hydraulic, etc.

Darth's easily sporting a 600 HP (flywheel) 346 without a doubt! 1.73 per cube thru a wet sump conventional package and a bone stock shortblock....this combo is getting it done!!

Still waiting for my next opportunity to drive the car.....bring the video camera!



-Tony

PS.....A loss of 90 from flywheel to rear wheel is exactly 15% (assuming approximately 600 at the flywheel) and in this case I feel that number is conservative if its anything but Im sure its real close

Love the write up! A few things that come to my mind when reading this thread....

1. Holy crap this was done on SBE ls1 and 91 octane! More static compression, flex fuel, ls2 block and a slight cam change to optimize those changes.....makes me want to empty my savings account LOL.

2. The smoothness of the MSD manifold graph makes me believe that the car will be more predictable when driving the car in all aspects which is great!

3. With a proper MSD, LLSR, and all the proper goodies, guys are getting close to hitting the hard limits of the factory ECU/PCM..........in a DD streetcar!

4. I think think this car will do very well at the track for a M6 car torque is broad and smooth and if spun hard it will definitely turn some heads.

5. Darth thank you for being transparent and honest with all the info you contributed to this community!

1. Yeah...still makes me grin like an idiot
2. I think that's why I prefer it. it may be "down" a bit on torque, but it feels like it helped tame the cam a smidge.
3. I've got VE cells hitting 122%
4. I think the real limitation will be the driver if i'm honest
5. Thank you so very much! I've learned a ton on here, so just trying to pay it forward.

What an awesome write up Jake. One of the best I've read. Read it twice so far. Great info here.

Your an inspiration to the community Jake! Not many people take the time to share in as much depth and detail as you have done. If there were ever a 347 build that needed to be took out of a car and strapped to WestTech engine dyno its this one! Wonder if Tony has a connection.......... be some cool stuff to see a write up or a shoot out with this thing
