Also what is your current 60'?? (My guess is 2.1-2.2) getting that down will help too.. I need to look at my old time slips.. btu I know my most recent ones from the 89 I was cutting 1.79 60ft. Granted the L98 (even with a Miniram) is different the the LT5, but I know my first 60ft with the Zf6 in the 89 are probably 2.1 or 2.2

Re: What do i need to hit 11.9-12.2 range
MY CAR WITH ALMOST THE SAME EXACT SETUP RUNS BETWEEN 11.78-12.20@117.80-119.10. HERES WHATS DONE TO MINE PORTED BY COREY HENDERSON . HE CUT THE WALL OUT OF THE PLENUM ON THE INJECTORS 1 IN IN HE BLENDED THE HOUSINGINGS INTO THE 2 PORTS . ITS BIGGER PORTING THAN MOST DO BUT IT SEEMS TO WORK. ONE THING I SAW WHILE AT COREYS WAS THE AMOUNT OF HP A GOOD DYNO TUNE CAN NET . THE CAR AFTER PORTING BUT BEFORE TUNNING WAS 385.THEN HE STARTED TUNNING AND ENDED @409.9 RWHP AND 373.66 TQ. I WOULD TRY TO FIND SOMEONE WHO COULD TUNE YOUR CAR ON A DYNO. THEN GET YOURSELF A SET OF MT ET STREETS RUN THEM @16-18 LBS OF AIR . LEAVE THE LINE AT 2000-2500 SHIFT @6900 AND YOU SHOULD GET TO WHERE YOU WANT TO GO . YOU COULD CALL COREY 210 867 6286 ASK HIM HOW MUCH HE WOULD CHARGE TO DOWNLOAD MY TUNE IN YOUR PROM. HOPE THIS HELP .PS MY CAR ALSO HAS A FIDANZA FLYWHEEL

I like to run it as it would be on the street, nothing better than to open up the Road and Track summary and see all of the $100-200K cars your car can outrun. LGAFF 92 ZR1 #234 |
