Ok... my 02 firehawk LS1 Auto trans.... looking to get some good opinions on what flywheel and rear wheel hp might be at. It will never see a race track (maybe once just to save the slip... but wont be beat on) and i dont really hotrod it. Just food for thought... and to create good friendly discussion.
Engine mods:
Long tube ceramic coated headers.
Full 3 inch exhaust with cat delete; resistored rear 02 sensors (i think); y pipe of unknown brand; single in dual out muffler unsure of brand but im told it sounds like slp loudmouth..... not sure has no visible markings.
Stock air box lid was modified by removing all the baffles and sanding smooth. Silencers still installed until i find a pipe to delete them.
Superchips cortex 2950 91 performance tune with 5 mph higher shift points and slightly higher line pressure. Fan speeds lowered (oem thermostat still... will get a 160 thermostat and drop fan speeds to 175/185 i think)
The tuner made a huge difference... three friends verified... it really did feel a LOT better... even if its all in my head... but it is a good bit quicker so i believe the hp gains...(roughly 20). Oh yeah... i was given it locked by a friend... he bought it used on craigslist and it was vin locked... so he gave it to ke instead of paying the 100 dollars on top of what he paid. I felt it was worth it. Also had another friend say if i didnt like it he would give me 150 for it unlocked.... win win.
So 335 flywheel hp stock. Add in long tubes... full exhaust... lets say 10-20 hp gain? A lid is good for 8-10 hp... i just modified mine so lets say 5 hp. Then the tuner... lets say 10 hp just to curb the mass of people who are smarter than me to waste money on a worthless handheld tuner and cut the advertised gains in half.. i will say.... 360-370 engine hp... 315 rear wheel...
How far off am i?
