Thats fast!

 

Good run man, love the mph

 

You see.. now i am happy with your MPH!!!!! 143mph is a bit shy for a 850rwhp car...
I bet with better "track tuning" you will get past the 150-151 which is what your car SHOULD AND WILL!!!! trap.

Dude congrats

 

Thanks everyone, I appreciate it.


sleeperz28- The trans was done by G-force. It has their 1st-4th gearset, 4340 30 spline mainshaft, and triple cone conversion. So far it's been working great, clicks right into gear without lifting off the gas.

We are a dealer for G-force, so let me know if it is something you are interested in.

As far as timing, I am running 19 degrees at peak torque and 21 degrees at peak horsepower. It lost power with more timing on the dyno.

The Highlander- Thanks, and fwiw this run was made at 24lbs of boost which I would estimate to be around 930 rwhp. I may put some 27in tall tires on it and try to break 150 as I'm out of RPM with the 26's.

 

How much boost did you see before????

i will be using 28x10.5 on back.. i expect around 9.8 BUT at 143mph or so... not that wicked MPH i could crank up the boost though... the ysi should support to almost 950rwhp.

intimd8... how much $ to beefen up that m6? i might need to do it...

 

Great times. Was wondering What kinda rings you using to withstand 24psi.

 

Jim, how many street miles do you drive that thing? Still on the same old shortblock that supported the S-trim a while back?

 

I think he is.. eagle crank, eagle rods, je pistons... pretty much what i had last time.. although i changed to a callies racemaster crank

Above is the link to all of his mods. I am following what he has done for my buildup. I am going to use the same pistons and the same rings. He is using the Speedpro Hellfire.
