terry.... i didnt watch all the runs yet but i think if you had downshifted one more gear or two, you would have probably pulled or at least hung with sherwin a lot more.

thats the thing i hate about these automatics, sometimes if your not at the right RPM and gear and you kick down, it'll downshift by itself - which to me causes a delay that isnt significant. i guess the shifting makes up for it.

We are misunderstanding each other, terry said about running JB2R on pump gas. So I was just clarifying that he said not to do that in some other threads....

Great Runs, and Comparisons....I look forward to more in the future....

Ah I see. I thought the R wasnt meant to be used with pump gas.

Shiv shouldn't do a 100 octane map, as it would be REALLY hard to have 100+ octane in the car.

He should do a 96-97 Octane map.

And there is no doubt v2 on 91 will pull a JB2 on 91 or 93 Octane.
As the JB2 runs equal with the v1.47 on 91 Octane and the JB2 doesn't seem to get the power gains on 93 Octane as the v1.47 does.

Every v2 car I've run in my v1.47 car, even with 93 Octane has pulled on me.

Hotrod and I are going to test the JB2R on a 95-96 Octane race gas mix vs. the v1.47 on 93 Octane next weekend.
Then we'll do a JB2R on 95-96 Octane vs. v2.02 on 93 Octane too once I get the v2.02.
I want to see what the JB2R does on race gas compared to v2.02 on pump 93 Octane for 93 Octane states.


Anyway, gotta run again, relatives coming over soon.

Happy Thanksgiving all.

He means that if you have the JB2R, you can still flip the switch for 91 Octane and enjoy a close to 40 hp gain. It's not like you can't drive your car on 91 pump gas once you have the system installed. It just won't be as fast when you flip the switch for 91 octane.. About even with a V1.47 Procede.

Yeah, I thought you had the same 2.02 map Shiv made 400rw on for some reason. No worries though, once I get a few more mods we can meet up again.

"R" needs 96+ octane, JB2 can run on 90/91 octane.

Here is the link:

http://s198.photobucket.com/albums/a...-Terry335i.flv



Here's the break down.

First off, let's say this, Terry's JB2R car and Sherwins PROcede v2.02 car were basically tied.

Now, let's clear up the air about the dyno amounts.
First off, doubtful Sherwin's car is making much more power.

He dynoed like 365 rwhp when he had catless DP's on v2.01 on Shiv's dyno.
He now has hi-flow cats which probably take away 10-15 rwhp but now has v2.02 which add 15+ peak rwhp. So I'd guess Sherwin would dyno in the 370-375 rwhp range on 93 octane
He did not have the same map as Shiv when Shiv trapped at 116.8.

Terry, on his JB2R with 96 Octane and his current set up has dynoed at 345 rwhp, but according to Terry, that dyno reads 10-15 rwhp lower than most.
So, I'd suffice it to say Terry, on a less conservative dyno would be in 360+ rwhp range.

That's within 10-15 rwhp of what I'd guess Sherwin would dyno on the same dyno.

So why were the races basically a tied if Sherwin has 10-15 rwhp more and same weights??
Automatic tranny. Faster shifts and lower final drive ratio overcomes the 10+ rwhp difference.

I've said it before and will again, the autos in the 335i just rock (for an auto).
Walked U saw me pull 1.5 CL's on JonMartin last night with my auto over his manual. Sure I had probably 175+ lbs less weight in my car, but he also has probably 15 rwhp more than me because of his catback.

I have not lost to a manual equipped 335i with similiar mods yet.

It was a fun time last night. Man was I tired getting home at 3 am!

More details in following posts.
Nice details...except: I don't think you can say for a fact that they tied due to auto vs. manual. Too many variable differences between the 2 cars.

Races are never really fair, as some cars are just faster than others with the same mods. WalkedU and I happen to have fast cars.. if you take my car against say a below average V2 I'd walk it, and if you took WalkedU against a below average JB2R he'd walk it. I think we felt it was a good enough comparo to call it a tie.

Hi Dennis,

Around 5-8 rwhp over 91.
