91 GTA Ramair2

I wish I knew what was up woth it But 16.11's is all it would do I thought these where suposed to be mid to high 14 car's.......
or low 15's at least.

I've seen l-98 time's vary from 15.40's-14.30's.

That's why i was a bit ticked when my L-98 was running so slow.
I my LO-3 wasn't that slow......

Rebuilt LO-3 with a 10.2:1 compression 3.73 gear's ran 15.60's all day long,in my 89 RS i used to have.....

But My L-98 hasn't had a tune up sence 1989.
So that's first on the list this spring.

Yeah a GOOD tune up with quality parts is always the first mod. Using brass contact parts(cap & rotor), spiral-core plug wires, AutoLite or Delco's, maybe Accels. Change fuel filter, PCV valve and run some "B12 Chemtool" Fuel injector cleaner,"just Pour It, and Floor It!", like it says...
Then, set the TPS(0.54volts@idle & 4.50volts @W.O.T. for MAF cars), Idle(air bleed), timing(specs on underhood sticker)
MODS:
K&N air filter with a cold air pipe, eliminating the stock restrictive canister & tubing.
air foil, remove MAF screens, port plenum just behind throttle blades, bypass the coolant lines past the t/b, adjustable fuel pressure reg, relocate the IAT sensor to inlet tubing, a good free flowing CAT & CAT-Back exhaust, shift improver kit, and if you have 2.73 gears, get at least 3.42's.
