So about a 35 hp increase..and a 41 tq increase

[Alpine335TT]

Well for the money I'm not complaining

[Boostin335]

if a jb2 car is making 305-310 whp and xede and v2 are suppose to make 360-370 whp..

I see and believe that jb2 cars are keeping up with xede and v2 cars.. but how is this possible.. "real world performance"

just dont see a 40+whp difference doesnt make a huge difference from a jb2 to xede/v2

[ArmyBimmerDude]

Something's not right here.....

[silvrevo]

click,,,,,,,,,, seems like a light switch just went on.

[Alpine335TT]

beats the hell outta me guys

[revah2]

Alpine, whats the difference is in STD correction. 304 SAE might be 310 STD

[musc]

Good job. Were you on 93 octane?

[RedGT3]

Taken from Terry's website.

the JB2 offers additional boost and significantly richer air/fuel targets. Gains average 35-45 rear wheel horsepower and 45-60 rear wheel torque.

What fuel are you runing 91 or 93?

Most xede dynos have been 310-320 whp range..nowhere near v2 numbers

What's more important than max HP figures is the area under the power curve. Anyone have the Xede/v2 power curves handy?

[Alpine335TT]

Yes. always 93

[e90AW335i]

Those results sound about right....Nice job....

If you dyno'd right after installing jb2 your ECU might not have had time to adjust.
Maybe you need to get another dyno in a few days to see your real gain.

You really have to look at the delta to get a better picture. Some of these higher HP #s probably had a better baseline dyno than 269 hp. Look back at Mr. 5s procede 1.47 with downpipes...he only had 326hp. I have seen stock PRocedes put down in the 330s. It's just a matter of what was gained, not the absolute HP #. 35hp is as advertised for a JB2 with no other mods.

I haven't heard much about JB2 hanging with V2s other than one match up where JB2R walked a V2. The JB2 is on par with PRocede 1.47 and the Xede, but I don't think there is enough matchups with V2 to make a fair comparison.

Drag times are all about conditions and drivers. A 40-150mph race using the similarly equipped cars is the way to go. Remember with the sport package, you have heavier wheels, tires, bigger brakes and heavier adjustable seats. A fully equiped car vs. a bare bones car can weigh a good 50-100lbs more I'm guessing...

Good point Sambonator. The JB2 curve mimics the stock curve, just with more power. The V2 curve is more peaky, but definitely improved over 1.47.

Im waiting to see 'ADHD' dyno results! JBS2 + DP's

Judging by CEAs track performance, the results should be impressive.

[boostin]

call me crazy but i don't think 35whp/41wtrq is bad at all for $375...

Your Crazy.......just messin with you, its a great deal for that amount....

[Noize]

That's substantially lower than I expected. With all the bench racing on here, I thought these cars were at least as fast as 1.47 or AA XEDE cars, but I think a 1.47 or XEDE car would walk away from a JB2 car.

I made 70whp with my v2 over stock, and on a Dyno Dynamics! With the 2.0.2 map, I expect at least 360whp on a Dynojet, and I'm 100% stock otherwise.

The fact the thing doesn't control fueling is the nail in the coffin to me.
