Headers and Intake will realistically add some PEAK 25-30 WHP. With Mike's dyno it was close to 40 WHP, he had a tunable strong CLS-5AT.

Also, I'm not building my car to be a "drag strip car." Just wanted to get the most performance out of my "semi luxury cruiser w/ some passing power"

If you really had no reason to reply other than to hate you need not reply again. I was looking for helpful responses, not ones bragging about a 20 year old Buick. :thumbsdn:

Ask typeR to dig-up the tape of the car burning the tires in first and second gear (with good tires).
Forget about peak/max HP unless you buy a 7-speed gearbox or CVT (or are interested in top-speed runs). Look to the tq/hp area gain (compared to stock) in the “useable” powerband.
The rod ratio is altered in a 3.5 and the intake air is moving a lot quicker at lower speeds (that longer stroke pulls on the air harder/earlier). Breathing at higher speeds becomes an issues and some upper end breathing design could push the peak HP a lot higher with a cam, head work, and other mods that would increase volumetric efficiency at 6K- to 7K- rpm.

With my old car (Grand Prix GTP) I was seeing consistent 60 ft's of 1.8, 1.9, 2.0 being the worst of them...this was with bulletproof axles, LSD, and slicks....but since I'm new to the CL's...what is considered a good 60ft? I've been racing for years, mostly American, and haven't gotten the CL to the track...I have all winter and early spring to mod...tracks don't open around here until about March

BTW, what year was your GTP and were you on the old Listserv Brian ran??

Voting "non-functioning IMRC" because my only "mod" was a hi-flow comptech air filter (and removed the resonator box from the intake path) and I was definitely in the (high) 14s. Then again maybe my car was strong and yours is a weak one? ![Dunno](https://acurazine.com/forums/images/smilies/dunno.gif)
NOVA had about 300lb weight disadvantage between our cars and he had CAI, headers, exhaust and I slightly pulled on him. Maybe it was a fluke but hey it happened.
edit - should have read the rest of the thread. so it was that. cool. glad that's fixed. =)
