I wouldn’t call it blocking. But yes.

 

Cool, I saw the broken diff in Ding's video. I'm curious how the power curve looks generally. I've seen so many of the OTS supercharger kit dynos where they're peaky like the OEM engine. I'm assuming a turbo K24 has a nicer power curve. It looked like your S should be in the same ballpark as Ding's supra. Jackie clearly had issues and I think you still left some time on the table. Should be a really fun season.

Are you allowed to swap out the diff and/or trans in that class? Seems like those end up being the biggest issues, mechanically, when the S starts to get up there in power/speed. Though there have been shops that have built diff/trans swap kits, most of them seem to be really expensive. Aero seems to be a bit challenging too, in street classes, compared to newer cars that have flat bottoms, etc.

 

That was the entrance to pit in. What was he supposed to do, come across to open up the line and then cross the line to dive into the pits? That's how you end up with a high closing rate crash.

 

Yeah we have a nice fat torque band and relatively flat torque curve. I’ll try to find a dyno graph but we ramp in boost slowly for drivability.

I need to break my habit of always trying to be in the lowest gear possible in a corner, I think many times I would do better being a gear higher. Turns 5-6 in this video is a good example. On this lap I got lost in the gearbox and basically coasted through those turns as I tried to find a gear. But being in a higher gear I made up all the time on the run to 7 than other laps.

For power we are in the same ball park currently. We can currently run the car at anywhere from 385whp-530whp peak. The tune we were running on this lap was just under 500whp. I think when Jackie has his car turned down he is around 460ish and when he’s turned up all the way he’s at close to 570. But power is only half the story. We have a big weight advantage, I believe we are currently about 250lbs lighter than he is and that is hufe. But but but his trans is current a big advantage for him, I believe. There are pros and cons to all cars and it’s fascinating to see how differently they make speed.

For power we will be looking for a wider range of boost control to broaden the range of tunes we can run, both on the lower end and upper end. At PRI last year we saw electronic wastegates announced. I’m very interested in these, for the tuning possibilities but I don’t think our ecu can drive one AND keep drive by wire.

Yes we are allowed to swap trans and diff, but we are not allowed a dog box or a sequential. We are planning on addressing the driveline after the next round at autobahn country club. It should give us better performance and reliability but we will be adding weight, I think the tradeoff will be a net-positive for us. It is expensive to play at the front of these time attack classes but we have incredible competition in this class and that’s what makes it fun.

Aero is an area that everyone is developing quickly, the unlimited guys are building full 3d models of their cars and doing lots of cfd work, I hope street mod doesn't get to that point. We get a lot of help here from Zebulon MSC out of Colorado who have helped develop a whole new aero package for SuperK this year. We are going away from our alumalite splitter on AP2 bumper to a 3D carbon splitter on a CR bumper. We will bring small aero refinements to every event, at gingerman we had a prototype of our new sideskirts and even added yagi diveplanes to the bumper mid-event.

As Mike from Professional Awesome likes to say - Good aero packages come from making a lot of good, small decisions.

There is more than just us and Jackie at the front of this class though, RS Motors has a killer Evo, Shawn Krebsbach has a monster evo he is working on, Dewey has the boogeyman, if everyone runs their best on a weekend pick 2 of those 5 to miss the podium. There are several others knocking on the door and getting faster too. Nobody is sitting still.

that statement was mostly sarcasm... I mean you did ruin his lap, but like Chibo said, you didn't exactly have a choice. Didn't mean to offend anyone here.

 

Even though he was on the racing line, he didn't exactly "ruin" his lap. He didn't do anything to make him miss his braking zone completely. Yes, he would have made him sacrifice a little time, but by no means did he ruin the lap.

 

lol. Jackie is a great guy and a fierce competitor, but I am a little sore about the way that story was told in his video. The irony is that on one of his blown coupler incidents I caught him in the exact same spot as he was limping back to the pits, just one of those things.

 

I noticed that at the 2 minute mark of the video. It looks like you put it in 6th instead of 4th and got lost with what happened - I do that quite a bit with 5th instead of 3rd under side load. Awesome driving regardless - didn't comment on it initially because I didn't want to be "that guy".

 

no worries, I totally got lost in the trans. Funny thing is that all the time I lost I made up with an awesome launch down to the next turn.

this lap wasn’t supposed to be the fast lap. It was the first lap to feel out how the car felt all turned up, with the plan being to fun the fast lap next morning. We never beat this lap.

 

that could have easily been .5 sec... which is the difference between 1st and 3rd place. but who's to say that specific lap would have even been any faster, even if he did have an open track that corner doesn't mean he would have won. and if thats where the track exit is then what are you gonna do about it. like I said before it was mostly a sarcastic statement.

time to make another video showing jackie blocking

I really made that comment sarcastically, I didn't mean for it to cast you in a bad light or anything.
