Default people with more aggressive camshafts, come in please

what are yall doing about the vacuum for the brakes? i recently picked up a cam specs are .232 .240 .600 .605 lift on a 112. do you have any problem with vacuum for the power brakes? if so what are you doing to make up for the lack of vacuum?

thanks
josh

Raising your idle rpm with a tune can help with larger cams having low manifold vacuum for power brakes.
I have a 'weenie' 224 cam in my 05 GTO, so my brakes were ok.... LOL
Hope this helps,

Brakes are fine with a SSHT here. 228/232 .610/.608 on a 111 LSA. Not huge but its not tiny either.

Haha ok. I really need a clutch before I can run anybody, it slips bad after it gets hot or something.

i was thinking maybe a vacuum pump like what is on the silverado trucks, seeing as how im a tech at a dealership, im sure it wouldnt be too teribly hard to find one laying around...
