I tested again this morning to confirm my tests last week. My car definitely picked up speed after driving for a few days. Here is the Gtech printout. I am getting 0-60 times in the 4.4 second range now. One run was in 4.335 seconds! Again, this is on fairly worn tires. As I said before, my Gtech has been pretty consistant with my time slips at the track. Furthermore, I took a video this time so you can see for your self. Go ahead and time the video with a stop watch. Look at the speedometer. You can see car is making good speed with the JB2.

Furthermore, you can see the speedometer is at 112-114mph with when the 1/4 mile light flashes on the Gtech Pro RR. Additionally, the outside diameter listed for a stock 18" RFTs is 25.1" (830 revs/mile), and my General Exclaim 270/30/19s' are listed at 25.5" diameter (817revs/mile)..per the Tire Rack Spec Table. So you can see that even though the speedometer is reading high, it is probably reading less optimistic than average. So how many of you testing on your performance meters have actually seen your speedometer in the 114mph range at the end of the qtr mile? Also, FYI the Tire Rack also lists the weight of my 19" exclaims as being 1lb lighter than the runflats. With my bigger wheels. 19x9.5", the weight for the wheel combination is probably very similar.

To achieve this on pump gas, with a soft launch is remarkable. Again, to me, my improvement over stock is 3-4mph. Exactly consistant with a 35-40hp claim. This is within the range of the Juice Box claims. So if the previous version Procede puts out 25-29HP more than the Juice Box at the Dyno, it should be trapping at 111-112mph. I'm just not sure where all that "dyno" power is going?? And if the new Procede V2 really makes about 60HP more than the Juicebox, according to the Dynos, then it should trap at about 116mph. That is going to be impressive! Up there with the new 08 Vette. Lets see some test results from anyone on the Procede V2 soon! Also, I had planned on doing some side by side testing with the Procede 1.47 this weekend, but the owner had to reschedule. So maybe next week. Will keep you posted. In the meantime, I can't tell you how fast my car feels.
Some 93 octane, and DRs would definitely help my ET, but right now, I am mainly interested in the Power and Trap Speeds. I'm dying to go to the drag strip again, but this will have to do for now. Especially since they closed LACR. And to think the JB2 does this with the most limited amount of boost compared to the other alternatives. As hard as I drive this car, from 55F to 111F outside, with no CELs, etc, I'm pretty pleased with the results. Can you tell by the video?

Man thats great! I have been planning on getting JB also but I am just waiting cause I know this engine is new adn alot of r&D is still going on. But time is making me lean to the JB

[///M3NACE]

thats fookin sick! Zo6 vs 335i? some1 do it!

i'd like to check that out in person.

i have e92 with 6mt and Xede r6 - no exhaust, dp or intake.

pm me the location and time. i am in southern cal.

Definitely, Im sure others would love to see the results. Let me know if your available this weekend.

[BoostedBMW]

Make sure you guys bring a camera.

[f30er]

that video's awesome, i'm still trying to decide between Procede 2.0 & JB2 and that video's makin me lean towards the JB2....

[mayanh8]

That gtech looked to be dead on. Video seems to be in the very low 4 second 0-60 range.

[jcarlucci1]

Can't wait to see how the procede run will compare!

[Bimmer335i07]

Damn!

Why is your fixed shift point at 7900 rpms

Because the Gtech RPM pickup is inaccurate on my vehicle. Therefore shift points, TQ/HP, are not useful. Secondly, because the Gtech doesn't have an audible beep at the end of the 1/4 mile, I don't want any lights coming on the Gtech except for the one at the end of the 1/4 mile. So I set the shiftpoint light high enough so it won't ever be a distraction to me. If you remember, last week since my car became faster, I had to reset my speed marker way higher. It was set at 104mph last week, and I was braking before I hit the end of the 1/4 mile!

Seems like a skewed experiment to begin with.
I dont trust the Gtech for one second...
If i wheel spin while recording on my gtechpro ss- it completely screws up my timing
For example- One of the runs i launched at around 3.5k rpms wheelspinned for about 2-3 seconds.
By the end of the recording i did 0-60 in 4.3 seconds and the quarter mile at 12.6 @ 115 MPH on a stock car (yah right)
Want to buy Gtech to track slip comparisons ?

I already took mine to the track, it was unreal how close it was. Almost exact. Of course I thought there would be doubters, therefore I took the video too. Out of dozens of runs, mine almost looked like the same line on the graph (consistant). And then when I did the mod, the acceleration graph distinctly moved upwards. If you are spinning your wheels, or have hop, yes, that will throw it off. Besides screwing up your E.T. So in your case, maybe it is useless till you can launch smoothly.

Great work again hotrod. The car definitely looked strong in the video. Are you shifting yourself or letting the AT do the shifting?

Leave it in DS, shifting by itself. One push of the DTC button. It's so automatic. LOL.

umm hwats up with all the "jb with gtech" posts, did terry make a bunch of names, start posting with them, and then do this?

[Driver72]

Hey Hotrod, yes it is very common for the speedo to read higher than what the actual trap speeds are.
These BMW speedos show about 2-3 mph faster at 60-80 mph.
At triple digit speeds they are often off by 4-5 mph.
When I did my runs months ago at Famoso, my speedo on my sedan was passing 110 mph at the line, but my traps were 107+ mph.

And the diameter of your nearly worn out Generals are probably now equal to what the stock 18" tires are at new.

It's just the speedos that read so far off, but the odometers are correct.

[Cornhusker]

I'm pretty sure gtech's are a bit off.

My best procede v1.4 runs were 12.58@113.3 and 12.66@112.4, 0-60 on these two runs was 4.23 and 4.29

I think the only thing they're good for is for you to know when your improving.

Gtech is very accurate as has been verified in many tests. Moreover Hotrod knows how to use the unit. His reports are the most detaild and best source of acceleration info in this forum. Thanks for your effort.

So you think I really ran a 113.3? Sorry man, G-tech are NOT known for being accurate, they ARE known for being optimistic. BTW, my runs we're the best of 15 and they were at 4200 feet elevation. G-tech's are inaccurate. By at least 2 if not 3 or 4 mph in the 1/4. I'm sure there are plenty out there who will verify this. Trust me, I wish I ran a 113 @12.58 @4200 ft elev.

I'm not bashing Hotrod, it's just how it is. maybe he ran a 107 @ best. If gtech's are accurate, just have hotrod go to his local strip and duplicate it and I'll eat my words.

[radgator1]

Nice results!! 109 is crazy fast.

My car is definitely running very strongly with the JBs2 and definitely faster than my previous "chip". I also think the runs are probably accurate but what may not be accurate is the slope of the road you are running on. Even a little down hill will have a significant effect on ET and Trap speeds. I can't wait until you get back out to the track and see if you can get these great times on some official runs.
