Zano:
SSRE runs their ultra streets at 10.75 to 1 on pump gas only (93 octane).if they mixed their fules they could run a whole heck lot more compression on the street ( street engine)..call them yourself and ask them...
i am telling you without a doubt that you can run your car on the street at 11.3 compression....Mix your fuel 93 and 110...or get some 100 street blaze or something comparable...i have a drum of 104 unleaded octane Sunoco oxgentated fuel in my shop..its yours for $300.00...come and get it...your 632 will love it..it sells for much more than that....
This thread has taken a sharp 90 degree turn...your question was it too much compression for the street...the answer is 'NO' if your doing some weekend warrior stuff.......i have a 67 camaro with a 511 bbc...it has 14 to 1 compression...me and my wife drive it to the local cruise inn's and hamburger joints....i run 112 Sunco blue ( Supreme)....i also took it to the track and ran a 6.07 at 115 mph over a month ago...would i drive this car 200 miles one way..NO..but i will drive it locally all around town and BUST anything that gets in my way...LOL......or capbale of it anyhow...
see the car in the show off section
i am not trying to convince you either way....but i have ran some 11 to 1 Hot" street cars since i was in high school...and never re-greted it...we used pump gas back then and never hurt anything..didn't know any better..i would say Mix it today because stuff has gotten so high to replace....11 to 1 is on the high border side of being too much for opump gas but NOT too much for the street.."weekend warrior stuff"...
whats spending the extra $20.00 at the oump when your filing up?..speacially if your just catting around town on the weekends and screwing with rice burners....the extra $20.00 is worth the smell if anything.
besides what ya gonna do if it checks out to be a 11.3 compression motor ?..tear it back down and spend big money just to be able to pay $3.50 a gallon for pump gas ???...if i were you i would mix the gas and leave it alone and enjoy driving the car......just my opinion...
let us know what Ross says.....
Good luck and enjoy..
