i need some advise from the pros
if you dont mind me asking, what are your finding with tire pressure on street tire? this is an argument some of my buddies and me have. in my opinion lowering the tire pressure does very little on radial street tires and from experience lowering it to much will actually hurt you.
Tom your mph is def there and your driving def improved throughout the day. So you improved with seat time and Cecil is not the best track. I live 20mins from there.
Your 330 is def slow to give you an idea I ran a couple years ago in 2009 this slip on a full weight evo 9 GSR lift shifting on street tires fl red stock block stock trans stock suspension the following slip.
60 - 1.693
330 - 4.787
1/8 - 7.340
MPH - 95.97
1000 - 9.532
1/4 - 11.409
MPH - 116.09
This was lift shifting street tires with 424whp. I am in no way trying to be rude or insult you merely for comparison sake and suggestions.
First I'd raise your 2step that launch i launched @ 6200ish as I had a twin disc which I'm assuming you have at least a twin disc.
Second play around with tire pressure, pm me and I'll tell you what I like and starting points.
Third your shifting def needs to be quicker, those shifts seemed to be like save the trans shifts no offense.
Fourth practice, practice, practice!! More seat time you get the better you will do.
I'm only 20mins away from Cecil be happy to meet up hang out and do some racing with you. Especially in spring as I will be doing a lot of testing there to get my car dialed in for 9s on stock turbo.
Please don't take any comments or my comparison offensively. Only meant to be informative and some suggestions for you. Feel free to pm me anytime as I said, it would be great to meet you and go racing!! HTH!!!

about the tire pressure.. as stupid as this sounds, i dont even know what it is right now.. id have to check the tires. but they are i believe 28psi - but ill check.
yes ill def meet up with you there.
i have a exedy triple plate hd - and yes i am kind of scared to really fast shift after what happened in ohio.. my wedge collar popped off even with a fork stop. since then tho i added more wave springs and changed to a stm fork stop. so far so good.
i only got 6 runs in because i noticed i was low on oil and didnt wanna risk anything.

another thing - when i shift i push the clutch all the way in.. im sure that doesn't help either. i will use no lift to shift next time then that will at least put me in the neutral zone as far as shifting speed goes.. ill be the first to admit im not that quick of a shifter.
im more accuracy over speed i guess you could say.. i didnt miss a gear all day.
Nice job really for your limited experience, nothing to be ashamed of.
Couple of things. First, our normal BR 2.3 will go to 8500 rpm without a problem at all, depending on the power curve you are probably better off setting the rev limiter up to make use of all the RPM you can. I'd actually say set it at 8800 rpm and then just work on shifting it around 8400-8500 rpm and in 4th gear let it eat and run it out to the 8800 rpm, which should be more than enough. The RE11 isn't a horrible tire, I ran some OLD RE01's in 245-45-17's and ran 10.2 in the Bish, I suck driving so I'm just saying it's possible to go fast on that type tire. I got the car to 60' in the 1.6X's on them.
Shifting out of 1st sooner is NOT going to make the car faster. Your actual launch was good, didn't sound like it hit the tires too hard and sent them instantly spinning to the rev limiter, it takes a lot of talent but if you can practice you will find just lifting a touch and then sticking it back to the wood if it's spinning hard will usually stop the spin. You want to make sure you ride 1st gear out long enough that the tires STOP spinning before you shift to 2nd gear, do NOT try to shift to 2nd if the tires are still spinning. Hurts the trans and bogs the car.
The entire ET is determined (well not entire but most importantly) in the first 330' of the track that's the first 3 gears, you will be in 4th before the 1/8th mile and from there it's nothing to make finish the pass, that's why the MPH gain is nice.
Good luck, it just takes practice, thanks for chosing our parts.

the 2nd run i videotaped did exactly what you said. after that run i made sure not to do that again..
Also that's good piece of mind the engine will take those high rev's.. i got the rev limit set to 8500 right now in ecu flash. car feels real nice up there. engine is smooth as hell, couldn't ask for more out of a 4g63. im extremely pleased with every single product i run of yours on my car.
if you dont mind me asking, what are your finding with tire pressure on street tire? this is an argument some of my buddies and me have. in my opinion lowering the tire pressure does very little on radial street tires and from experience lowering it to much will actually hurt you.
the front are 18.. the one must be leaking or something. i wonder how long it was 12psi for. im glad you asked me to check that.

you cant shift before hitting the limiter in those conditions i was in.. the mph of the car wouldn't be enough.. it would drop out of the powerband no matter how fast the shift was because the mph of the actual vehicle rolling wouldn't be enough for the rpm..
do you see what im saying now? there's no getting out of hitting the rev limiter in that situation i was in.. the problem is, i was hitting the limiter to long.. i couldn't time it right.
but as you can see the slips i was slowly tuning the car and starting to time it better. i went from a 5.3 to a 4.8
for example, say you have a FWD car and you spin 2nd gear a lot.. if you spin and shift asap your rpm is gonna drop a lot in 3rd and bog down the car.. no matter how fast the shift is because you didnt let it spin 2nd enough to grab 3rd at a high enough rpm in the powerband.

when you do it correctly, and have traction from the launch till the top of first, you will see that shifting to 2nd early with a powerful car like yours will help your short times, but you need to shift fast and time it right.
I see what you're saying but i think you're confusing things... sitting on the limiter in 1st 'waiting' for the tires to stop spinning won't get you down the track faster. The idea is to launch the car without spinning and bouncing off the rev limiter. to do to that you need to modulate the clutch and throttle during the launch. it may mean only going WOT in 1st for a spilt second till you shift gears, but in no way do you ever want to be sitting on the limiter in the beginning of the pass waiting for traction. if you are then you need to modifiy your technique or setup.

.. i was trying to time the spin (like David mentioned).. you know how its spinning but the speed of the vehicle is still increasing, but you cant see the actual rpm because its tagging the limiter?i was trying to get it just right to where the 1-2 would be smooth and no delay.. most the time i was overreving it like you just mentioned, the 4.8 330ft was pretty damn close though.. i remember the car felt stronger going into 2nd on that run.
i didnt even think about working the gas with the clutch.. that probably would of helped big time. kind of like torque control.
I was saying the mph looks a little low based on your vdr results of 600, and I am aware that it is heavy. I didn't mean any disrespect by my observation

Lots of good info here. Subscribed for pointers also. I had my best 60fts on street tires set to 18psi though. On the stock clutch I was cutting high 1.5 60fts and with my Exedy twin sd 1.6 60fts. I haven't had a chance to test out my Exedy twin HD yet.
ya i dont know.. i thought it was mph'ing ok. it still had the wing on and stuff. the wheels are pretty heavy. what do you think the mph should be? and compared to whos evo thats full weight? the mph is #9 out of 20 cars on the mph list.. so i didnt think it was to bad. its got more mph in it yet also.. im gonna guess up to around 134 on street tires.. no clue on hoosier.
