Nice work pure and terry what fuel were you running and what kind of meth mix

[RingMeister01]

Nice work guys. That thing is a serial killer

We ran 100 octane with 100% meth in the M4. Not sure what Terry was running.

He told me he was down to about 13 psi from the normal 15 psi at sea level. That jives with what I was seeing on my car. I was about 1.5 psi down on average. That's life with a supercharged car.

This can give the outside car a small speed advantage at the start of the race.

It isn't as bad as it might look in the videos. It's as fair as anyone wants it to be. I made all my runs in the outside lane (GoPro mounted on right side), and there was plenty of room to adjust my speed after the turn. I'd always try to be ahead of the inside car when entering the turn while working towards the agreed start speed (40 or 50 mph depending). By the time we were pointed straight, we'd be even and at the same speed. It's all about gauging your speed properly.

I've had cars jump the start cones on me at the Airstrip Attack events. It really just comes down to the honor system. I try to be as fair as I can be, but maybe that's just me.

Straight from Drew.

While I have dynoed over 700whp, as Terry mentioned in his first post, unfortunately I was not making that when we ran, the car was actually boosting around 8-9psi on our runs, as well as Terry's, it's normally at 12-13 @ BW with this pulley, so I was probably around ~620whp on those runs, not 700whp, due to the manifold lifting up on one velocity stack in the front, it's quite common on these manifolds, unless you have brackets on all 4 corners holding it down, I only have them on the back.

Yes, the list is long.

I appreciate you clarifying that. I don't want to take anything away from the amazing work Jesse @ Pure Turbo has done, and I'm tired of this manifold issue, it's unreal that it's not completely fixed by now, because the car is finally all dialed in and performing well.

To be fair I never spoke to Jesse about it at the event so he wouldn't have known, he had already left, but after I ran Terry in the shootout I showed him the issue with the manifold leak, hence the reason he explained it in his thread when he posted the videos, which is a class move IMHO. Surprisingly the car still held 8-9psi, I got very lucky and still edged them out.

Terry actually brought it up it in that same thread you referenced:

Back from another great event from the guys over at Shift Sector. This time a 1/3 mile roll race at Willow Springs. The BMW turnout was impressive, tons of F80s and a handful of F10 M5s. Not to mention a few larger turbo N54s. They even let a few N55s in to race.

I ran our F80 M3 most of the day and it performed pretty well. I had to limit boost to around 25psi, which is around 570whp on a dynojet, to keep the trans from slipping. And traction was an issue most of the day. Some runs DTC would kick in in the middle of 4th gear which wasn't fun.

Most of my traps were 138-142mph with a best 60-130 of 7.6s. I ran better later in the day when I started doing rolls from 60mph for better traction. I didn't get many kills but I did manage to take home 2nd place in the BMW shootout. I lost to Drew in the finals by less than car, although he was also down on boost. We'll rematch at the next SS for battle of the best M3 platform.

... and Terry almost beat me! Before I had the issue, my car trapped 148 MPH at the event, the highest of any BMW or AMG there, also higher than Adam's Turbo S, (147) which beat or ran with just about everyone and for now easily pulled Terry's car.

Again, this is not to take anything away from the upgraded Turbo S55's, they are very impressive and eventually will surpass my car, especially in this 1/3 to 1/4 sprint format at Big Willow, but that's racing, higher HP cars have issues, just about everyone one of them, I was very fortunate to even get the win.

Also Terry and Jesse's Pure Turbo M3/4's had solid traps, that's the reason I had to run them in the finals, they out trapped all the other modded AMG's as well, so another all BMW final.

I care.

Agreed though, his car is impressive.

[Pure Turbos]

Thanks for the info Drew! What a fun day. The 3 of us dominated the AMGs. That's a win all around

No doubt Jesse, and a few of those AMG's are fast, I have a feeling at the next Big Willow 1/3 or 1/4 mile sprint event, it probably won't be me on the podium for the BMW/AMG shootout.

I agree run what yah brung, Drew still competed and won. But a lot of people actually care to know the details. The whole point is to compare these cars and power levels. Otherwise why even record videos. It is good to know the power levels of each car, to get an idea how the new M3/M4 are coming along in its very early stages of tuning. Just like how people want to know that Terry's Pure Turbo car was running about 5psi less than the other Pure Turbo car. His M3 was getting DCT slippage anything more than 25psi. Hopefully Terry can get the DCT problems sorted and Drew can get his problems solved for the next event. Then get some clean runs between the three at full tilt.

Yep, exactly.

But, that's separate from the manifold velocity stack/coupler issue, which has plagued my car for too long.

[Mike@N54Tuning.com]

Here are some videos from the BMS M3 development M3 running a JB4, PURE Turbos, and meth. Boost was reduced to 25psi due to transmission slippage and tire spin was an issue all day. They still managed to take home 2nd place in the overall BMW shootout!

[DLSJ5]

Fixed your post Mike since we are talking about reduced boost levels. Regardless the JB4, pure turbo combo is the real deal, and 2nd place with all the BMW and AMG cars that competed at this event is huge, he almost got 1st place!

Hey Drew,

I remember you having that issue way back when. Probably going back to the first Coalinga event. I figured you'd sorted that out by now. We didn't get to talk long yesterday, so maybe you just didn't mention it. I ASSumed everything was good with the car.

No problem man, yeah, I thought I had it fixed as well. Spoke to ESS they are sending me custom brackets for all four corners, should do the trick. Regardless in short sprints like that, I will still have to fight those cars off, especially if they were not at full potential, either. As mentioned, I think both were actually turned down for this event.

[MasterC17]

If we can get the DCT clutch slip issue solved with Gintani, I'll be purchasing a set of these turbos.

Geez...poor little 2 series...

What tune are you guys running? Jb4?

I was on Map 2 on 91 gas. All my morning runs where really horrible. I finally managed to squeeze a 1/4 tank of 110 and run Map 7. I was able to put up some decent runs towards the end. Thanks for posting up that sweet vid though I'm gonna be seeing you guys soon for my upgrade.

Afternoon run against a stock GT3.
