Was under rated. Now I ask you. What are some other cars that were under rated as well. Here is my list.

98-02 LS1**
93-97 LT1
03-04 SVT Cobra
05-08 Mustang gt.

Your turn!

Do you mean under rated as HP figures intentionaly being stated low?

Or under rated as in not given enough credit by the media and general public?

As far as your list goes, I think the only one under rated HP wise is the LS1.

MAYBE the Cobra, but I don't know enough about them to say. Although I remember reading back in '00 or '01 or whatever how they were actually OVER rated, and didn't make advertised HP. Ford recalled a whole buch of them, IIRC.

I'd say the Buick Grand National and '89 Turbo Trans Am are two other GM cars that are under rated HP wise.

As far as the TTA, it was rated at 250hp/340tq and Car and Driver got 0-60 in 4.6 seconds and a 1/4 mile time of 13.4@101.

Since the L98 cars made almost that same power, and were mid 14 second cars at best, I'd say the TTA was definitely under rated. C&D thought they same thing, they estimated that it was more like 300hp.

Doesnt matter. Numbers or not given props. On another note I saw an 04 svt put down 387rwh stock. Id say thats highly underrated. Oh and I completely forgot about the TTA good call. As far as L98s go. I believe they were rated properly. Although I did see a stock one (90-92) go 14.0 at 99.

The SRT4 was underrated for power back when it debuted in 2003. Most believe it attributed to the fact Dodge ran it on a dyno with a hot intercooler. Needless to say, it like the 03-04 Cobras would dyno much higher than what was stated.
Also another boosted 4 banger, the Cobalt SS supercharged, for the most part their advertised HP tends to be their actual FWHP.

1996-1999 Oldsmobile Aurora - the ones with the distinctive dome shaped rear end. The V8 in the car was strong and it had the best interior. I loved mine - real pleasure to be in and drive.

supras are under rated as well IMO some people are believers, but next time i hear "dyno queen" im gonna bash my head until im retarded too, built they are known to go 8.45 in the 1/4 and top speeds of 250+ i wouldnt say thats a dyno queen

Alright alright, take it easy Cobra people...

I'll agree that the LT1s in the Fbody were underrated. mine dyno'd 245rwhp and 283 rwtq when it was basically stock. it had what i refer to as maintenance mods. ie an MSD cap/rotor on the stock optispark, MSD wires, NGK plugs, and a K&N panel filter in the stock airbox. i even still had the donkey dong thing. based on the 20% dl loss of an auto, thats about 306HP and 354TQ. pretty far off the 275/325 stock stats for what was essentially a stock car with new plugs/wires.
