All the dyno tests on the C&L plenum are on 99+ gt's with PI heads of course and I'm sure everyone has already seen what I'm about to say on the c&l site but maybe some didnt so heres the link and they get decent gains on an almost stock 97 GT and they say mac Throttlebody but dont say the size...hmmm heres the link http://www.cnlperformance.com/plenum09.html

I'm gonna call C&L and ask what size MAC TB that was cause if its just about a stock 97 gt same motor in my 96 and with the 70mm tb plenum gave 7-10 horse and like 10-15 torque dyno tested that might make me feel alittle better about the plenum sitting in my room!!!

Those numbers are not too helpful without air fuel curves. Any gains could have simply come from them leaning out the A/F curve. I know they "claim" it was kept the same, but I like proof. Yes, I am skeptical of this product on 96-98 cars. A couple HP, maybe. 7-10hp, doubtful.
Plus, they are recording gains for parts of the graph where the TC wasn't even locked up. 15 ft #'s gain, lol. How many stock, auto, NPI 4.6's lay down 320+ ft lbs to the wheels at less then 2000rpm. That alone shows me that they are trying to pull a fast one over on customers.

lol true I'm just trying to make myself feel better for buying it last month though I havent put it on yet cause I want every tenth of a percent of horsepower out of this thing even if its 2-4hp and I dont know if I should go to the 70mm tb like they "claim" cause I dont wanna lose anything....

Hey guys, I have a 2000 GT, and perhaps I don't understand the differences in the power plants between my car and yours, however, I seem to have gotten pretty good results with the C&L plenum. I have very few mods, as you can see below, but my car seems pretty quick as compared to stock. I have noticed that it just seems to pull better all the way to redline.

My 1/4 mile times are in the very low 14's at 98 mph. I should be able to break 14 real soon with just practice and my 0-60 times are 5.55 to 5.65. This seems to be a marketed improvement over stock of mid-14s and 0-60 of 5.9. BTW, I have a 5 speed convertible, so I am pulling a little more weight.

I think people should be skeptical in general, and I think this debate is healthy. I wonder is C&L would take back products if you are not satisfied with results.

I will be adding the rest of C&L's intake bolt-ons very soon (Mass Air Kit), and I am looking forward to see how that helps. I really think that when that I happens, I will be taking advantage of the plenum and 75 mm TB that I have and will hope for even more improvement.

Good Luck!

Big difference in powerplants, you have PI heads which is 45 more horsepower over 96-97 and 35 more horsepower more then 98's.
