I'll let you know when it's confirmed. I'm trying to schedule a date when most members are free, but I didn't want Sundays in case of family time or even some who wanted downtime. But Kody likes Sundays. I don't mind either way, but you know me- just trying to accommodate and gather as many as possible.

Great numbers! Seems like with each pull the timing was advancing I'm guessing? How much time did you allow between runs, and was this done in 6th gear? I'm assuming this is with the tune installed also?

bnizzle - How does it feel on the road with 500hp at the crank?

bnizzle did you ever get a baseline stock?

I'd guess it would probably be around 350ish whp. Gaining 75whp and about +100hp at the crank with a couple bolt-ons and a tune is just insane. To think, another 10-12whp can STILL be had once RR Racing releases their intake.

I didn't do baseline. In retrospect comparing the numbers would be best to see how much was gained after each mod. But at the same time, it's more than just a butt dyno feeling for me. I see how much more speed on a corner I can take and how much faster I can accelerate from a dig or rolling. What I'd really like to do is get an open stretch and record my times. Members getting 3.8 0-60s is pretty darn amazing in my book, and 0-100 now become so much easier and without hesitation. And unlike the dyno, I'll get to see how the removal of rotational mass effects the speed times.

Do you know what's the difference among the pulls to have a 20hp and torque discrepancy? Were they cooled down vs hot pulls? Was the power decreasing/increasing with successive pulls? Nice numbers!

I think the kclv got better with every long hard pull until it capped out. The runs were 5 mins apart from one another

It was about 5 minutes in between each run. This gave Kody enough time to "place bets" on how high the next value of HP or TQ would be. We didn't have access to the timing, but I would presume so, given the increase after each run.

Honestly, the combination of I/E/H/tune really shows how capable this car is. I'm not after the most HP for an F or even a car in general. I just want consistency and reliability with the added power, and I've been enjoying the car more and more with the tune. But everything in moderation. Traffic in LA county still sucks, and I'm planning on testing my times against my previous track runs.

There is some enhancements that can be done to the car to gain more power, but couple this with losing weight and rotational mass, the competitive perspective will be even more enhanced than simply getting the car to 500 at the crank. The quick answer....I enjoy it greatly!

How do users measure this KCLV count? Need a datalogger, etc?

I think the only way is if you have Techstream which sucks because how many guys out there with F's are going to buy Techstream + cable to just find out the KCLV number?

I know it's beneficial and almost necessary to know your KCLV number especially with the tune to see if your timing is being advanced to the point where it is being seen and you can feel the increase not only butt dyno but also on a real dyno where the increase in timing will show the full benefits of the tune.
