Re: THE QUEST FOR 500
type M&W Ignition into Google
what fuel pressure are you seeing? your post there says you use the stock fuel return line, can that keep up with an A1000 pump? You should be able to do this with a stock ignition, you don't need mine. How old is the igniter? Has the MSD failed yet? |

Re: THE QUEST FOR 500
Stock ignitor , msd box seems ok , dwell set to 4 ms on coils and fuel pressure was 40 base and would rise 1/1 with boost . The stock return is large enough to keep pressure at a 1 to 1 ratio

hey man seriously i think is the tunning are you getting steady afrs during a wot run ? i doubt it but let me know |
Re: THE QUEST FOR 500
get over the tunning thought its not the problem , if i knew how to post pics i would post the dyno sheet . 12.5 afr from 10 psi up no dips a perfect straight line . i made 49 pulls on the dyno trying to figure out the issue and the only time i would get a clean pull is right after i would pull the pugs and clean them , i would then get 2-3 pulls before the plugs would foul again (litterally dripping wet) . i made 486 at 6000 rpm before the clutch fully slipped still had 2000-2500 more rpm to go on a weak clutch. im gonna try some different non resistor plugs tommorow ad see how that goes .

kool check it out. will suck if you buy an expensive ass ignition system and be on the same boat.. maybe injectors staying open ?? and yes can be plugs too. not heating up what they are supposed to. are you doing quick pulls? or you let it idle a while and then do the run? |
Re: THE QUEST FOR 500
the 1600 cc injectors are know to be a bit bi t chy so check it out

Re: THE QUEST FOR 500
Something is wrong besides the ignition if the 486 at 32 psi is correct? My REW did 470 at 19 psi with really fat air/fuels. I stopped at 470 actually because the MSD was starting to have issues with that power level, it developed a miss under boost that would come and go. I have since switched to a HKS twin power and it seems to pull clean. No need to go coil swapping if your coils are in decent shape, I have seen stock FD coils with ign amps go to near 700 rwhp.

with that said , have you had issues with the ngk race plugs , it almost seemed as if the 10.5 was too cold for single runs on the leading side . the trailing side looked better but still cold ( wasent cleaning deposits).
Im going to go buy a set of br10eix's and a set of b10egv's today and se what happens the br10eix plugs have work for me very good, for my cars and customer cars. i also use 11.5 |
