Would you run 87 in any other 11:1 engine? I wouldn't, and I wouldn't run 87 in the Scatty Pack (wish I had one).

Shoulda just bought the V6 Doc, then you could run spin tech oil and 87, but I know you wanted to look cool apimp



gM..... that ECU .... what’s the timing retard range ? .... and ORE blow a hole in the piston ! Switching back and forth ??!!

87 in an 11 to one motor ? ... there’s a famous OEM motor that was I think 11.2 and the OEM almost directed it to be 87.

QUITE HONESTLY... when I found out SOME PARTICULARS about the SP ... I almost kicked myself for buying it because the SP you cant put any type of trailer hitch on it. Like for hauling a small boat or utility trailer.

The LOOK ? .... how about that Charger GT ??!!
