Hey guys, I was just wondering would it be okay to run on 91 octane gas for a built head. I know I would maximize the power potential with a much higher level but wanted to know your inputs. Any help is greatly appreciated.

 

what is a built head? one which has increased compression? or the port and polish, larger valves etc...

 

This head is freshly ported and polished by Joe Alaniz. Supertech oversized stainless steel valves (1.0mm exhaust, 0.5mm intake) with Eibach dual springs and custom titanium retainers. The head has new valve guides and seats. The head combustion chamber volume is stock.

this head. It was made for boost.

 

91 will work fine. You will see no difference from the stock head except more power.

 

thanks phil

Don't worry about keeping up with me. You car is going to be faster
Besides, mine still looks slow

 

Have you thought of running water/meth injection ?

 

i never did. Honestly i'm a noob to water/meth injection. Anyone know a thread that will educate me? Doing a quick search it sounds very interesting.
