Numbers are great to post, but absolute values don't mean anything especially when every dynometer is calibrated with slight differences due to allowable tolerances. For example, people will provide opinions about those numbers were posted higher than their readings, or vice versa. While it's nice to have beast numbers, we focus on the uniqueness of the power delivery and power differences that are found between the factory and the JR kit. To this, we applaud Jackson Racing for producing a high quality kit that adds to the vehicle with no additional equipment absolutely required.

this thing is quiet. nice

Christmas is the season for making a list.

The CARB tune itself cannot be altered. However, you're able to load up any other maps you acquire from tuners with the same license.

In short, the EcuTek license allows you to tune however you want, but the CARB tune itself cannot be altered or used as a base map for further tuning. You (or your tuner) have to start from scratch or from other existing base maps.

I agree, I was more curious what the torque curve would look like for the final 200 rpm. If the torque was still going strong at redline, it could mean it's worth bumping the redline to about 8000 rpm. Just a thought.

That would be a noting feature, but we're not going to increase the redline simply due to reliability reasons. We short shift on track now simply based on our experiences with previous stock motors so there's no point in raising the redline for our purpose.

Yeah that makes sense given the engine failures you've had. Are you going to continue to short shift at the track with the JRSC on it?

Yes. There is a positive correlation related to how fast you shift, how aggressively your shift points, and how quickly you hit the gas which could affect the DI seals in a negative manner. In other words, it's extremely possible to recreate the failure, but the amount of time it takes to recreate the failure will vary based on engine to engine. There is much more to discuss on peak performance and sustained performance, but in general, I'm pretty sure 99% of the community doesn't feel like destroying components on their car all the time so we're here to prove there is a way to have high performance and good reliability too!

On a side note, this actually cleans up driving technique significantly and Mike has shown significant strides in improving his shifting technique due to this fact.

So I drove the car around on Monday-Wednesday this week, and here are my impressions street driving.

- The kit makes more power EVERYWHERE in the powerband, whether you're full throttle, or just gentle on the gas and driving completely normal.
-- Even at part throttle, the car pulls more than WOT stock. By a lot.
- The kit makes noticeably more torque, even when starting from a stop, so you'll need to get used to giving the car less gas when you start from a stop, or you'll slip the clutch more than you intended to.
- The kit REALLY pulls up top. After 6k RPM, you're REALLY moving.
- The kit's noise is virtually imperceptible to anyone who doesn't know what to look for.
- The low-rpm off-throttle noise is addicting, and people familiar with aftermarket centrifugal superchargers will recognize the noise.
- The kit doesn't suffer from heavy heat soak at all.

On a side note, I had some seat time in an Aston in the past few days. Dat V12.

thank you for your impressions on this kit, sir.

Baseline was 173HP is your baseline?

173whp is our baseline is 173whp

We're going to be using the CARB tune for a bit, but will eventually be getting the car tuned after we get more supporting mods.

As far as CARB goes, we're supposed to have zero further modifications that affect emissions. E.g., the catalytic converters need to stay, unless we get CARB approved replacements. It would mean that there would be multiple CARB stickers on the car as well.

The powerband doesn't look interesting, but I really need some seat time in one of these to make a choice. Torque valley looks great, but I can't get over the low numbers - though it puts things in perspective...75whp stock at 3K RPM? Yuck.

Would you say that's around 300chp, @CSG Mike? And just to re-confirm: on Cali 91, on a CARB legal tune, stock exhaust?
