c15 & 16

An everyday use tune...........hmmm what about all the hard part changes, do they count?

My everyday tune will do roughly 1100Hp to the tires. The torque at this power level is above 3600 Lb-Ft at 1800 RPM, I have no idea what it is at a lower engine RPM, but I'd think it would go up another 200 Lb-Ft by 1400 RPM. At Antrim's dyno contest the torque was above 4000 Lb-Ft at 1900 RPM

 

Most impressive, Sir!
And that is your "daily driver"?

 

I'm reporting you to family services, you shouldn't abuse your clutch/tires like that.

 

C15 to C16 is pistons, rods, crank, turbo and software, not a difficult change but as others have said the crank is pricy. Could probably do a C18 for less money as there are more second hand cranks around for them.

 

Stick with a C15 or C16,Bore size on a C15 is 5.4,C16 is 5.5 and and C18 is more but not sure what it is,the only way they get a larger bore is by making the liner thinner as the blocks are the same.
A well built C15 is the best. . . . . IMHO

 

Just as C16KIWI said.
I considered a C18 till i did some research(gotta love the www). As Shaun said, can build whatever you desire, but have to have enough material left to hold the motor together. A man that i have much respect for said if i was looking for big horsepower for a short duration(pulling,etc), build an 18 liter. But he also said for a long lasting,dependable motor stay with the 15-16 motor.
BTW, i believe the C18 is 5.7 by 7.2 bore and stroke?
If only there were pistons availible to stuff that 7.2" crank into a 5.4" liner motor... what a torque monster it would be??? (Mr. Haney, any ideas...?)

 

Thats why I think the C15 ACERT is a good start,longer stroke and thicker liner
