Re: xr_8sprint and brenx!!!!
I am not doing a rebuild. My block/bottomend is 3 years old. I've just replaced 2V heads with alloy 3V's as they didn't make enough torque or hp.
2V heads tuned on slicks struggled to do a 2m burnout (no brakes)
CHI 3V's untuned on slicks I dropped a 100m burnout no worries (no brakes)
I'd say I've had a large hp/torque increase purely because I don't have any traction and it's running like a dog. Once it's tuned it'll behave itself. If I can I'll get it too the track soon. Just scrounging the $ to get it tuned.
