Car was running great the night before but as soon as I got to cordova it started breaking up in 2nd,3rd, and 4th gear in the higher boost range......im starting to wonder if the E85 winter mix found its way into the car...

11.1 @ 1251.5 60 foot

Curious as to what that 11.5 pass would have been with a 1.5 60ft....

That 1.5 60' is insane, I would kill for one of those. Especially for 17" ET Streets. Which suspension are you on again?

Congrats on the times BTW.

The suspension (with the exception of solid subframe spacers) is BONE STOCk...and when I say stock.....i mean, its 20 year old stuff, lol

Ahh stock suspension makes sense... It actually helps to be honest since you get all of the weight transfer. I actually have trouble getting any decent weight transfer even on full soft on my Tein coilovers.

You are right there, just a little more boost/timing and you will see 10s!

I don't blame you, I still like the fine control of clutching and shifting.

Great lookin ride man!!

What Exactly was wrong with the th400?

Also I think you can cut that 60ft down a little more and also not get that small bog you got going on by holding that 2 step a little longer.

Personally I Pre-stage and Bring it up on the 2 step and roll into the stage light by using my ebrake to stop myself and also pre-load the drivetran so its not a terrible shock. I think your car has alot more down low. I would say a clean pass all the way your lookin at a 10.8

I'm actually running ET Street Radials.......big difference between that and just ET Streets (they are bias ply)

The size is 275/45/17's

I dont spin in any gear except for the launch

I really like driving the car around, its a street car. A th400 is 3spds, and 3rd gear is 1:1, which is identical to 4th gear in our Z32/RB trans......imagine trying to drive to the drag strip w/out 5 gear

Add to that.......the heat. When you have a pretty high stall converter, its going to be slipping ALOT. Slipping leads to heat, and that heat transfers right into the drivers compartment. On a 20-30 minute jaunt, I'd find myself sweating with the windows down

The unfortunate part about track days like the one I just attended is that its full of alot of novice drivers, who may not be familiar with the staging process, so rather than have my car sit on the 2-step for extended periods of time (for those of you who dont know, its not good on valves) I just wait until I see the yellows.......now if I was competitively racing, that would be a different story

I agree the car has alot more down low, but my whole goal is 10's in 'street' form.........to be perfectly honest, i didnt touch a THING in this car when i went to the track sunday, I didnt even touch the tire pressure. I literally unloaded my tools, went to tech, and pulled in the staging lanes.

I actually have my 2-step set to disengage off the clutch switch, so I wouldnt really be able to hold the 2-step out more........for some reason my VSS wasnt sending signal to the ECU otherwise I'd be able to set the condition for the 2-step to be on for anything under 10mph or so....

HAHA I understand about the Novice driver part! There at every track. Luckily at my local I get alot of solo passes which help esp with staging.

Wat I was referring to when i said hold your 2 step longer was just bringing it up on it a little quicker than you was. From what I was hearing in the video Your turbo was not getting spooled enough before you hammered it. I think if it was held about 3-5 sec longer it would pull threw that small bog and Honestly I think you could see a 1.4 60ft.

If your racing against Drivers that take a long time to stage. The way to bring it up without having to hold it forever and wait on them is pre-stage and wait on them to fully stage, Bring it up on the 2 step and roll it into the stage and then there is no waiting.

What rpm do you have it set at?

Its right around 6k right now.....

It looks like it was in full boost (25psi) on the launch, im not sure if you have the ability to see AEM logs, but here is the one on the 11.1 pass...

I have the 2-step enaged off of switch 3, which should be logged, so you can see when I dumped it

indeed

Theres a switch to turn on the mirror defrosters, and since I wont ever use that, I wired the line-lock into that switch for a 'stealthy' look

How do you know these guys who you view as novices arent intentionally burning you down at the line? J/K

you should probably just camp on the green and set up for a perfect launch. forget the RT to get a good ET.

Sweet!

So you're launching at 6k? Do you let off in first to get that traction back or are the tires just hooking up like that?

I also have line lock!! OMG!! It saves your brakes so much HAHA, I love it too, Its also good for when someone is riding your *** and you come to a red light!! I have been known to sling **** all over someone before LOL

I never worry about R/T unless I'm actually in a competition, which hasnt been for a few years.....when I was running my last actual brackets, I was cutting .05-.06 on the pro-tree

Man, you guys are making me miss the states bad. The best we can do here on Okinawa is a Gtec, but I'm not so sure how accurate it is. The roads here are so bad I spin all the way through 3rd on 275 nitto's I'd stab somebody in the face with a hot soldering iron to cut a 1.6 60', or even just limit my wild wheel spin to 1st gear.

Stock suspension is working that good for you, eh? Making me think about going to JY.

I really like your car man
