Hey Kevin, you should come to the car meet we have going on in Lewisville, November 8th! Did you know about it yet?

Can't wait to see what my brother's Trans Am puts down now. Last time it was around 297whp mostly bone stock. This time with headers and a dumped exhaust with no tune, we're expecting some loss on the low end and better power up high. This will make for a good baseline to compare how a tune will help (when he gets that done), and what an untuned 'bolt on' setup can do going up from a stock setup.

Oh and be sure to have some ear protection -- that car gets pretty loud!

P.s. time to update your signature/car specs.

At my dealership we put nitrogen in the tires of all of our cars. I can't say anything with regards to seepage, but I have noticed that nitrogen does result in a lot less "low tire" warnings once cold weather hits.

Ditto at Don Davis Nissan -- when I bought my '09 coupe they mentioned nitrogen in the tires. Something about being lighter and overall better. I still got a TPMS warning light once or twice when the weather changed over night but nothing repetitive. First and last car with TMPS + Nitrogen that I'm aware of, so I can't say if it was better or not in any aspect.

Welcome! I used to have a Nissan a year ago. Drove nothing but Nissans since '01 unti lthen (if you don't count my Neon which was my first and last foray into domestics).

BTW did David mention he prefers techs tighten his oil pan bolt with air tools? If you want to stay in his good graces and all...

Sampak, I'm on my phone and can't see images. What were the numbers?!?!

Hey man, sorry I came in much later in the afternoon so couldn't meet up. But yah my car put down 239hp/237tq. Torque's lower by ~15 ft-lbs than I thought, but might have been due to needing to start the pulls at over 4k RPM to avoid autotragic downshift.

Must say it was way better than I expected from my old car + Mustang's notorius reputation with lower figures haha.

Well, here is my dyno result!

Hah yup, it's pretty unusual for a Lexus to sound that way to most people, especially one that's 16 years old as it goes off from a light. It's not super aggressive or loud but I'm thinking of changing that up just a bit, and maybe get rid of some drone inside. Definitely fun to putt around with on a daily drive.

Do have any mods done to the Lexus?

Not myself, but the previous owner appears to have deleted the rear 2 mufflers, Megan EZ street coilovers (was slammed w/ 19s, I raised it up to where it is with factory 17s), and LED inner tail lights, dark tint all around and dark parking lights on the front there.

Yup I agree, as much as I enjoyed my '09 Altima Coupe 3.5, the 4.0 V8 in my Lexus is just more beefy, plus I get 2 more doors, for the same performance essentially.

Welcome! I have a friend at work who drives a modded 6spd 2012 GT 5.0 as well. A bit funny, he admits, being probably the 1 of 2 Asians driving 5.0's in DFW haha, and coming from imports (350z) but he swears it's overall more fun due to the insane power (plusit sounds awesome). Sadly he'll be out of town for the meet, or we'd get a good comparison of both your cars.

Anyway if you think you're good at rambling, you haven't seen anything yet.

See you Saturday!
 

Oh, and post up some pics mang!

Haha, wow old post!

I DID get the y-pipe shortly after, but even with an ebay exhaust (not the dual fart cannons, but the single in, dual out) AND RL Ypipe, I went up against an all stock '09 3.5 CVT coupe (like mine) and we were almost even up till 80 mph, after which it SEEMED like I pulled ahead just slowly.

Moral of the story - my car sounded awesome, but was maybe .05 seconds quicker than stock.

His turbo Altima coupe though...even with 3 adults seated that thing hauls...

I'll be there, most likely. (98 lexus gs400)
