I didn't think your exhaust mods were quite a 15 lbs savings either.

But if you weighed them than that's that.

In that case of the 36 lbs I'd say:

25 lbs is sport package
5 lbs is Sirius
6 lbs is Premium package (leather, folding mirrors).

The sport might be 40# more if you consider my factory 17" rims were maybe 5# lighter each than sport 18" rims. The exhaust was around 16# on the bathroom scale and I maybe added a pound with the cutouts. Maybe splitting hairs here.

Big picture, during those runs WalkedU and I were the same weight. If I were to line up with a 100% stock sedan with sport, leather, sirus, premium, etc I would be ~148# lighter, or ~165# if you consider rotational mass. If the drivers weighed the same.

Yup, but I think rotational mass is worth more than 1.35 lbs for every pound lost.
We both said we thought it was around 1.6 to 1.7 lbs for every 1 pound lost.
In that case the 148 lbs weight difference of your car would be about 180 lbs taking that into consideration.
But as you said splitting hairs, but still relevant.

Wait but most of the weight loss was with the rim hub close to the center of rotation. OK now we're really splitting hairs.

Driver 72, do we both have the same wheels and tires? You have 265/30/19's on the rear of your car also? And the coupe weighs what, 22lbs less? (About 3 gallons of fuel).
So we would probably be the same with you having 1/2 tank, and me a little over 1/4.

Yup.
Again, if you can try to make your 1/4 tank and be about 95-96 Octane (but no more).
I'll make as close to a 93 Octane mix as I can and try to be around 1/2 tank.

Good, that means I will only have to buy about 3 gallons of high octane

By the time you get home there will be none left, lol!

Nice videos! Looks like I need to get back to working on a 16psi map...

[Driver72]

Oh, BTW guys, for those who weren't there, even though these videos were edited, ALL the runs were back to back and took place within a 5 minute period.

see the thing i don't understand AT ALL is this...one map is a race map using 100+ octane...another is using 91-93 oct with more use as a daily driver.... i would think your pretty nuts to be driving every day putting race gas in and pushing the car to it's limits with race gas....makes no sense and seems very very stupid...now shivs map seems great for both everyday and track driving...it also has a lot more features and accomplishes this more saftly than the jb2r....i think it would have been A LOT more fair if it was a race map vs race map

Walked U was using the same mix as Terry.....At least that is what was stated in the start of the other video.....

for every 100 lbs on a 3500lb car it takes away about.1 0-60 and double the 1/4 so 175 lbs a lot of weight!!!! A LOT

It was basically 14psi vs 14 psi, both had race gas. The JB2 doesn't really have a race map, its the same JB2 with a totally seperate switching device to increase the boost almost to the level of the Procede. So it sounds pretty fair to me. And yes, when you are done with the race fuel, you have to take the extra 30 seconds to switch to just the JB2 operation. Its such a tedious ordeal! Its basically because in JB2R guise, there is no sophisticated timing control to rely on from an aftermarket controller. But for all that extra $$$, this is what gives the Procede the extra 50hp in Dyno power over the JB2R, isn't it?

This is the deal.

The JB2R requires about 95 Octane to run properly without issues.
Terry recommends 96 Octane to be safe.

The PROcede v2.02 needs just 93 Octane pump gas to run at full 100%, and has a slightly detuned version for 91 Octane states.

The other night, both Terry and Walked U's car had roughly 96 Octane in it.
Walked U didn't have to put the race gas mix in, and it probably didn't do much for him, as the tune he has is the default settings to run on 91 Octane.
True, if he had bumped the power up to the 100% across the board, he would of run even stronger.

He only put the 96 mix in so people wouldn't say, "yeah but he was on only 91 Octane"
Really that stock ECU and won't do much between 93 and 96 octane.
And since the PROcede v2.02 map Sherwin had is tuned for 91 Octane (not even the full 100%) the only power gain he got from using 96 Octane was what the stock ECU would adjust for.

I think we know the stock ECU will adjust a bit up for 93 Octane over 91, but again, it's doubtful it will give you much, if any, more power on the 96 over 93.


So, yes, for the runs to be completely fair on the tuner front, Sherwin would of needed to run a race gas map of the PROcede v2.02 (like the one Shiv had on his car when he trapped at 116.8 mph).
But since Shiv has not even officially released the v2.02 map, he surely will not release his race gas map yet.
Therefore the comparo was as close as it could be given the circumstances.

But I agree with you, that is the biggest drawback of the JB2R (needing to put race gas in all the time to use it and benefit from the extra power).
For many that's not an option if they don't have a station that sells race gas near them. For others it's a bit of a pain, as the only gas station that sells race gas may be a dozen or more miles away.
It's nice that the v2.02 can be run on 91 octane and get significantly more power than the standard v1.4x or standard JB2.

The weights of each car were about dead even when you took the passenger's weights into consideration.
The differences came with the mods and transmissions.

It would of been interesting to see if both cars were manuals or both were autos.
It's safe to say the autos are worth 1/2 to 1 full CL in these cars.
So cars with autos have an advantage right off the bat with that.

Keep in mind on pump gas the JB2R customer still gets ~40rwhp over stock.

But we arent supposed to run it on pump gas right?

Really?
I thought you could not safely run the JB2R map on pump gas?
I thought you recommended 95+ Octane and even on 93 it would/could cause problems and throw codes?

Unless you meant JB2 customer gets roughly 40ish rwhp over stock.
That I know to be correct.

Ya but terry was on the JB2R

So I tried my hardest to do an apples to apples comparison octane wise.

Once i get a 100 octane map should be better.

I think we all agree that on 91 pump vs 91 pump the v2 will edge out the JB2
