I did the same and verified the 3.69 gears were what the seller claimed.

My 2011 convert seems to pull harder off the line but the mid range is still weak. I suppose the only sure way to add some ponies is a dyno tune for $600 to $800.

Modern naturally-aspirated engines are rather well optimized from the factory due to the current horsepower wars and EPA requirements. $/HP for mods has risen dramatically over the past thirty years. It used to be one could expect 1 HP per $20 spent, now you're looking at $125-$150 per HP. Forced-induction engines tend to be quite conservative in tune for warranty reasons so big HP can be found for rather low prices.

If my ARK exhaust got me 10 HP, I'll be happy. Though it's heavier than stock parts it's 100% 304SS so it'll still be in use after I'm dead.

"IF" is the question here and at what RPM level is this achieved? Ten HP at 6000 RPM at the expense of torque at a much lower RPM range is worthless from my perspective.

Good point on the forced induction and I'm starting to think that a 335 BMW couple might have been a better purchase for me. I've had several Nissan products though over the years and love their reliability.

I'm hoping for 13.3's. So far 13.41 is my best with a 2.0 60ft.

Do you have test pipes or HFC? I also have NST underdrive pulleys with helped me run 12's and trap 108-109 consistently.

Thinking about getting a AL driveshaft from the driveshaft shop.

Did you see/feel a big difference with the underdrive pulley?

Your not tuned? If not that's your problem. Get your remaining mods and get tuned so you can hit 12's.

I just ran a 2016 V6 Camaro a couple of times from a rolling start to 70 or so and it was dead even..they're supposed to run 13.6 in the quarter. I suspect that from there on in he would have owned me.

Of course not! It was a roll race at the track, duh..


What's everyone doing to launch? I know this has been beaten up and down but I'm a good driver and just cant get out of the hole? My best 60ft is 2.4 and it makes me sad
