I am in the process to start my jump from street car to full race car. My CR is looking to be 13.6:1. I am going invest in RC 370cc injectors and try to tune out detonation with 93 octane. I have 404 cams so I will bleed a certain bit of the compression away right.

Any advise would help!!

 

Get a wideband o2 sensor and don't run lean.

 

i dont think i would be very feasible...

 

I dont know if u still get knock on 93 octane or not if u retarded the timing signficantly.

Either way if u wanna run 93 you might need to induce some more overlap and pull alot of timing, you could prolly just make the same power with a lil less comp and less overlap on the 404's and more timing.

Why are u limited to 93 octane if its a full race car? If u could splash in a some 110 u would have no worries

A 13.6:1 CR motor with 404's is undercammed. If it's full race, run bigger cams if you have the clearance.

Let's put it this way, I want it as close to a full drag car as I can but still streetable.

I would like to be able to use pump gas so I never have to rely on race gas. Also 93 here is $2.14 a gallon and 114 is about $4.00.

 

I think 405a's work prime with 12:1 or a little higher CR so you could do that and It would bleed enough CR that you could run it no problem on pumpgas even 91. Tuned right of course.

Good point!
