I ditched the top mount, looked and worked great. thats what i ran 12.4 on stock motor, with 70k on!

But, the new setup is much more efficent and spools my sc6265 about 700 rpms sooner!

Im breaking in this sleeved motor now! shooting for low 10's..

I have a customers car i tuned last week at 420whp at 20 psi. we shooting for 11s this next week, just waiting for his twin disk to come in so when can slap on the slicks!
