Okay so I had to race a Magnum Hemi today. So I turned my boost up to about 20 psi. All seemed fine until I got on it hard (in the race) and it cut out on me. I have colder spark plugs from autolite, a map chip (phearable - John Vega) with no boost cut, and a 3 bar map sensor. Anyone have any ideas of why it may be cutting out?

 

if your on just a base map thats not very smart, you cant just turn up the boost when you feel like it with out a tune to go along with it. What size gap on your plugs?

 

we set the gap at .028

 

bet you ran out of fuel

 

I was thinkin it might be that, but theres no tellin because we dont have an air/fuel gauge yet.

 

lol , no a/f guage, turning up the boost without a tune, and racing on a basemap? are you trying to blow yourself up??

 

get a good wideband in there before you fry all your hard work.

 

wer going to put the boost down

 

uhh DO NOT run autolites on a honda!!!!!!!!!!!!!!!!!!!!!!!

lol, ngk only.

 

NGK doesnt make the plug that I need anymore?

 

uhh and why wouldnt ngk make the plug you need when all boosted hondas are running ngk's lol

short story..i had a car come in once that wouldnt start at all. it had new autolite plugs in it..put ngk's in and it fired right up.

i cant believe its 2009 and people still dont know NGK plugs only, oem or ngk plug wires only! NO matter your setup.

honda even tells you on the sticker of the hood to only use ngk.

 

haha, yeah and dont forget turning OFF the boost cut !! all no-no's!!
and go get yourself a set of NGk-4554's

 

Stock basemap is deff not cool, boosting at 20psi specially with out correct fuel and ignition timing. I put money on that you didnt have enough fuel and it cut out. Make sure you get it tuned specially a z6....

 

another simple answer...GET IT TUNED!!!

 

everything previously said and STOP STREET RACING !!!!,unless you were at the track then nevermind

 

glad you read everything

Edit: My bad...wrong forum. It was at the track.

 

what rpm did it cut off, also did you smell something funny just before it cut on you
