Here are my dyno results for my IS250 6-speed 2008 with 7500 miles on the odometer.

All I had done to the vehicle is an HKS HI-power exhaust and Fujuita Intake. I had some free time at school so I was allowed to get my baby up on the dyno. The car sounded extremely awesome in the dyno room.

My buddy put up his stock 2000 Acura 3.2 TL and only made 176 hp and 172 tq.

Seems very low.
Especially after an Intake and Exhaust upgrade.

Neither really adds much power to these cars... some intakes might even cost power by sucking hot air.

An axle-back exhaust, even on a 350, only gains maybe 5-7 hp.

that is300 you race must not be tuned, i'm close to 200rwhp and i think 201ft/lb tq and if i'm not mistaken, the 250 isn't lighter than the 300 is it?

(K&N FIPK2, OEM headers, megan-y, borla cat-back)

your friend can't drive worth a damn, or his car runs like ass... according to the is250 door frame here at the lexus dealership the is250 weighs in at 4615lbs, while and auto is300 weighs in at 4300lbs. i'll update you on the weight if it's different on my 5spd

i'm not hating, i think it's a great car (it's just slow as balls)... just don't believe it will walk on my car. you're 315+ lbs heavier than me, and you're pushing like 25rwhp less than me... do we really need to do the math...?

i think lexus was stupid to not put a manual trans on the 350... ah well...

forget about just the weight.The IS250 is underated and tested differently.If you drive manual IS300 you should be able to edge out the manual IS250.Mazzuri dynos 196hp and 195tq or around those #'s with just headers nothing else.
