I will keep you posted. I have ran 15.3 1/4 acouple of times.
I now have Tein Suspension, Hood scoop over the intake, soon Fidanza Flywheel, and ACT clutch Installed!! I hope to break 14's full interior ON 17's. I will rpbably run with my 16's just cause they are lighter!!
Oh yea i Ran a 15.3 with
intake, UD pulley, and cat back exhaust!!
13's on @ 5 psi is probably do-able, though that is probably not being to friendly to the tranny. Come to think of it, 13's seems kinda low for a 5 psi RS. Larry Ganz made some low 13 second passes at 6000 ft. and 14 psi (20% loss of power at that altitude), but maybe im just being pessimistic. I think that those would probably be HIGH 13's, depending upon other mods, such as a flywheel.
14's should be doable without new cams.(cam timing is a different story) You will have to optimize the setup for drag racing, clean up the intake tract, open the exhaust, optimize the suspension, alignment and most of all perfect your driving skills. .1 lost in the 60ft =.2 at the other end. Slipping clutches cost time and hurt the big end too. Clean up the shifting as much as possible, find the best shift points and soon you'll be seeing 14sec runs. Practice is key, consistency is the goal so that changes in setups are shown more prominently as opposed to drivers margin of error.
its possible but not easy. wolveRS from clubsi Si (i dont remeber his name at i-club its different though) recently ran a 13.9 running 5psi, and that was spinning out all the way through fisrt gear, thats right, he spun out all four tires. so he is capable of clicking off an even lower time.
with a good set up and ECU managment like tec-ii or haltech (which wolve DIDN'T have), 13's is obtainable on 5psi.
I raced a guy that was pulling a 14.85 quarter mile and won by about 2 1/2 car lengths. I had a decent start (spun the tires for about a second) which is probably the reason that I won. I was also being REALLY hard on the tranny by power shifting, but I dont do it very often, so im not too worried. My synchros are definitly getting a beating (going into third it grinds a little). Here is a list of my performance mods so you can kind see what I am running. Also I am at about 1500 feet in elevation.
Working Hood Scoop and vents
ScoobyRacing Torque Chip II
Direct Hits Ignition
Cat-Back Exhaust w/ Arospeed Muffler
Rallispec Cat-Eliminator Pipe
ClutchMaster Stage III Clutch
COBB Short Throw w/ CUSCO Bushing
H&R Springs w/ KYB AGX Struts
20mm Rear Sway Bar
Front Strut Tower Brace
STI Tranny Mount
STI Engine Mounts
Also when I raced him I didnt have the COBB intake or the Torque Chip, I had a Weapon R Intake when the race occured.
