new dyno #'s with fm13
new dyno #'s with fm13 Started off before changing the tune (useing old hammer cam tune) it pulled 413hp/399 tq.
After tweaking for a while Allan got it to 419.93 hp and 405 tq. and just for ***** and giggles ,we ran it through the muffler and pulled 396 through the muffler. Car drives better , sounds better and performs better with the fm13 then the c1

Oh since dynoing with the c1 , I also changed from 4.10's to 4.30's in the 12 bolt and put a chrome moly steel driveshaft in place of aluminum one.
roughly 25 hp gain with the swap

Great numbers! I just put the FM13 in over a TR224 and will be dynoing next week. This is with AS 5.3 heads that flow 314 and a stock geared 10 bolt. Should produce some exciting numbers.
BTW.......Does your car have Forgleline wheels on it? I think that was you at Thunder Shootout. I tried to catch ya, but missed ya. Wheels look VERY good!

I am running the Edelbrock catback which for some reason they chose to make a 2.75 inch Intermediate pipe. I dont know if it is the size of the I pipe or the muffler but It sounds awsome but flows like ****. I always use the muffler to slow me down at tracks that are strickt. I can always count on loosing 2 mph and going 2 tenths slower through the muffler.
I think with Hooker and Magniflow it is only around 5 to 10 hp loss.

Chad, it was good seeing you again and congrats on the numbers. I was very impressed with the numbers you are making through your drivetrain and mild heads. 
You need to get in touch with Justin about those heads. lol

Car feels strong now , I am going to stick with the heads I have expecially after hearing the 987 springs should be taken off. I am waiting till next year when the car is paid for , then it will be AFR heads and a fresh bottom end.
Considering a offset ground crank for the 20 more cubes but have not seen to much on them. Just depends on if I am willing to put a cage in by then too.
I dont have my graph by me but teh tq peaked at 405 @ 4800 and the hp peaked around 6400 I beleive but pulled strong on tq from 3500 and up . Tq below 3500 was still awsome but really shined above 3500.
