Just kinda feelin out the idea of runnin more timing. Currently I am running 26.5 degrees and have no knock with a 150 shot. Just wanted see what other people were running with similar mods.

 

Is this a dumb question or does nobody know?

 

DO NOT tune your car with the knock sensors!

If your car knocks on the spray its probably to late to save it.

Take what ever the max timing you run on motor and take out AT LEAST 6* for a 150 shot.

Timing doesnt make a huge difference in HP you will find more power getting the A/F correct then adding timing.

 

Like ATV said.

I don't know where people got the idea they can tune off knock sensors....

 

+1 never tune off the knock sensors, the only accurate way to tell is to read the plugs.... For 150 shot I would take 4 degrees out.

 

well i haven't tuned off of knock sensors but I was talking to some friends who run close to 30* in there big blocks. Just wondering if anybody else was running that much or what.

 

My car likes 26* on the motor most are 27-28*

 

So you think I should leave it or even cool it down a little? I've run at least 3 bottles through it already at 150 shot.

 

im 26 on motor with a ms3 cam only motor, went to 27&28 and only picked up a few so we put it back to 26 to be on the safe side and run 20 with 100 octane on a 150 shot... afr 11.7-11.9.... i dont know how your running 26.5 on the shot, id check afr

 

hmmm Matt at Texas speed seem to think 26.5 would be fine and so far it has been. Haven't checked my afr so I guess i'll do that next.

 

my cam only car has a peak of 27*
150 shot ill pull 3*

 

If you doubled it to a 300 shot would you only pull 6* out?

pull 2 more degrees out and run it and I bet it does not slow down.
Then lean the car out with those 2* still out and run the car and I bet it goes faster.


You guys can be out in left field with a 150 shot and not hurt anything, when you turn up the wick is when you need to know what going on.

 

thanks wayne. its not on the car yet, brent will tune it

 

Is that whats in the tune for N/A timing?
How are you pulling timing for the 150 shot?

150 shot and you dont know what the A/F is?

 

No problem, and I think you meant BRET not Brent.

 

Ya that was what TSP tuned it at and no don't have clue what my A/F is and the truth is since my first post on here I ran another bottle through with no prob making that the 10th bottle so............. fck it.

 

NICE! !!

I see a forged motor in your future.

 

For a 150-hit, most of the cars I tune end up leaving at about 26-28 on motor and 20-22 on the jug. There is just no good reason to be at 26.5 deg on the bottle. It's not making a bunch of power with the extra timing, it's just pushing you a little closer to the edge.

 

I run 27-28 on motor, 20 on the 150 hit, 93/100 mix.

 

spraying and dont know the a/f..... wow.
