Detonation in 3rd gear @ 5k RPM, blue box @ 7 psi
Greddy SOHC kit
NGK BKR6ES plugs, gapped at .030"
greddy blue box
stock pump, injectors, pressure
7 psi intercooled on a sidemount
93 octane Holiday gas
I did a 3rd gear pull yesterday and starting around 4k rpm my engine started sounding like popcorn being microwaved. I was only on it for about two seconds, then I let off. I don't hear it in second gear, only third? My car runs perfectly fine, it only made that sound for two seconds yesterday. I'm thinking:
read plugs, replace as necessary
get a walbro 255lph intank (HP or non-HP?)
retard timing 1 deg. at distributor
anything else? I just want to make sure that I don't blow up my motor. I'm not going to race it till next season anyways, just a daily driver for now. Advice welcomed.

you could try retarding the timing, have you had it tuned??? doesnt the greddy kit normally come with 310cc injectors for there blue box's????

blue box isn't tunable, SOHC kit doesn't come with injectors - blue box is made to work with stock injectors.

look into that pump or retard timing. i have both and have run 10 with no problems. blue box, rc310s, aem fpr, walbro 255, 2 degrees retarded, NGK BKR6 plugs at .032, dsm 1g smic, profec b, apexi powerflow filter, 93 octane. no detonation thru-out the year at 7 psi daily.
what octane gas u running?

so retard timing 2 deg. at the dizzy, buy new plugs (BKR6E gapped at .030"), put in Gumout Regane FI cleaner and Walbro 255lph intank? anything else?

cool thanks, so it's a timing issue for sure, not from running lean?

You could also run bkr7e's just to be safe as well... works fine for me and a friend... both d16's with greddy kit

k, I'll get the BKR6E's because the 7E's are overkill for my setup. I'll also retard the timing 1 deg. at the dizzy, but should I do 2 deg.? Hopefully that should fix the problem without having to buy a new fuel pump.
