I don't even know how to start off this thread, that's a first.

Last night Intmd8 (Jim M.), who is the tuner at Speed Inc. (www.ls1speed.com) was able to dyno my car for the third time... and the results were awesome:

A few dyno comments:

Dyno #1
-450rwhp
-6 psi
-Slipping blower belt
-Electrical anomaly noted when datalogging

Dyno #2
-560rwhp
-14 psi
-Overly large torque converter, the old one flashed to 6900 during the pulls
-Some belt slippage noted
-Electrical anomaly largely gone

Dyno #3
-705rwhp
-Roughly 17 psi
-23 degrees of timing at WOT
-New Yank U4000 converter installed
-Belt was tightened, early pull was 666rwhp with slippage
-Pulled to 6700


Jim is planning to dyno the car one more time in the near future to play with the tune some more and to do some more formal testing of the Griffin intercooler. But Jim told me last night that he was very impressed with this intercooler.

If we were to assume that the drivetrain loss through the Moser nine inch rearend and the non lockup turbo 400 transmission was ~20%, that means the engine is producing 840fwhp.

I did not sleep at all last night I was so excited!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Thanks and continued thanks to all the folks who have helped this project come together!!!!!!!!!!!

 

John, that's freakin awesome! Glad to see it coming together!!

I know we had this discussion in another thread about drivetrain loss, but what would you estimate % on an M6 with a Moser 9"?

- Dug

 

Sweet deal, now hurry up and call the wether gods and order some nice weather to start racing!!!
Congrats! Speed did some great stuff for you.

 

YOu must be disapointed

you should be able to dip in the 9.50's as long as your not to heavy

congrats.

you still drive it on the street with the 400turbo and no power steering?

what tire size you using and what are you planning on trapping at what rpm with the 400 and 4.11 gears? doesnt see high enough

will the 28" tire be good for the 140's you should be at?

 

Nice to see one of your projects finally work.

Congrats and enjoy!

 

I also want to thanks Harlan and ScottWS6 for their help, Harlan helped pick the longblock components, and ScottWS6 helped with assessing the dyno numbers and the direction of the stock cube setup...

 

Very Cool! Can you post the Dyno Graph?

 

yah post it up, this thread is moving fast

 

Very fast. maybe 9's!!
john, no thanks to me? I was a good ball buster!

 

Great HP what was the TQ????

 

Let me see if they can get us dyno graph today.

It was hard for them to get a solid torque reading since it's a non lockup converter, but it was around 625rwtq I think.

Doug I have heard 10% loss for T56 setups.

Smokin, I am going to remove the 4.11 gear and install a 3.70 or 3.50 gear. I will race on a 28x10.5 M/T ET Drag.

 

Great job!! Cant wait to see track results!! What gear/tire combo again? 3.50/28?

Should be easy nines

Manual valvebody in the tranny and shiftlight right?

You are going to have a lot of suspension tuning to do me thinks

 

Yah, manual valvebody and big ol' 5" tach mounted in the center.

The elders feel that 3.70/28 is the best combo.

 

705 unlocked ? awesome numbers man.

 

Good job guys...... John, if you can't sleep now what will it be like after you put it on kill and let the brake go for the first time? I want a picture of the smile on that pass!
Kurt

 

Great Numbers, 705rwhp!
J

 

Thanks John!

 

Thats fuggin badass! Congrats on a sweet combo.. get it to the TRACK!

 

nice numbers.

You have never driven a car that powerful have you John?
Do you plan on getting a NHRA license now?

 

Congrats John... looks like it's really coming together!

Track times would be awesome...
