New T28 Pump Gas Time

[DSMPowerTSi]

I ran my car for the first time this season on Tuesday. The car was on 93 Octane and 22psi dropping to about 20-21. I'm pleased with the time slip but was wondering about my mph maxing at 108 and not going above 105 by the end of the night. I did a log afterward and found out I had peak timing of 10 degrees The car was tuned decently well but I guess the addition of cams made it run extremely lean. I also bested my 60' of 1.81 to a 1.66. Anyway, the run looked like this.

60' 1.699
1/8 7.889
MPH 85.93
1/4 12.444
MPH 108.35

I retuned the car back up to 15+ degrees of timing and plan on racing again tommorrow to better my time.

that is ####in awesome man. Keep up the good work.

edit: What track were you at? I'm also in jersey so maybe we can hit up a race day together.

 

[DSMPowerTSi]

Thanks for the reply. I race at Atco raceway. Its in Southern NJ past Chatsworth/Barnegat. PM me if you ever feel like taking a ride, im down there frequently.

 

[CanadianTSi]

Very nice ET...I wish I could drive like that

 

[Generation X]

Very nice times. Keep us posted.

I hope you don't mean your highest timing point was 10*!?

If you ran a 12.4 with peak timing of 10*, you will run even faster giving her more fuel. You're lucky you didn't blow your engine with 30+ counts of knock.

After the track I logged a pull and my timing peaked at 10 degrees. Two weeks prior I added cams and retuned it and had 17 degrees of peak timing. I dont know how it just got lean all of a sudden but it did. I had to add about 15% more fuel to get the timing to 15
I'm def going back tommorrow, hopefully I'll come back with a better slip

 

[WhiteCloud]

Just so you know, a good timing curve will peak closer to 20 than 10 or 15. If you're not getting at least 19 degrees of timing at 6500-7000 rpm, you're knocking enough that timing is being pulled--1 degree of timing for every 3 counts the knock sensor picks up on 2gs. Timing is power, and I am shocked that you ran a 12.4 with less than 15 degrees peak timing.

You must be a great driver! Very, very impressive numbers for a pump gas run on that turbo, IMO. Try using some octane booster mixed with pump gas before your next pass, and maybe richen your settings up a little bit That should put you right about where you want to be. But definitely fix that timing. You are taking some big risks with a stock motor if you continue to push the car this lean, and you aren't going faster because of it (pulled timing).

EDIT>> Nice work on that 1.66 60 foot as well Nothing better than hearing a nice *CHIRP*vvvvvVVVVVROOOOOOOOOOOOM* out of the hole--until you worry about all the drivetrain parts you just broke

Nice ET....!

You guys gonna race at E-Town, that is where I will be most since I am 30 min away. Unless I have to go to Island, which is not the best, but you get more than 3 runs (which on some nights at E-Town you won't). I will be there in my hoopty, nothing like a car that needs an entire front end, but is mechanically sound. Eventually when I get cash, but for now I love having such an ugly quick car.

See ya all there, look for the black talon, with a big FMIC, and the car looks like someone attacked it with a bat.

I should mention this is my first time racing the DSM, but I have raced Turbo VR6's and S4s in the past, so I finally came full circle (since my first car was a talon). So it should be a fun learning experience.

My friend went to Raceway park Weds. night. Paid $29 to race and made 3 passes. I pay $13 to run at Atco, race 10 passes, and watch for 4 hours. BTW, they paved the burnout box at raceway park to cement

 

[PGTred95]

I think me and some buddies are gonna shoot down to Atco after work today.
Not sure if I'm gonna run, but I'll probly be there none-the-less.

I'll keep an eye out for you. My car is also a 97, red, 24r, cf hood.

 

[Black95TSIawd]

I'll be at Etown April 23. Hope to see some of you there. Jersey representin.

I would go to Atco, but since I am 30 min away (North) from E-Town, Atco is pretty far from me.

I will have the beast running till I break axles, the car dyno'd around 450 awhp, at 27 psi and 17 degree timing on pump baby. Ugly but fast.

I need to get a damn cage in it now, so I will run it once at Island, hopefully they won't boot me, but E-Town will def boot me after one sub 12's run and no cage. I will be running all the time this summer so look out for a brother.

 

[Black95TSIawd]

dont the new rules state that you need a cage at 11.59 and faster for a cage? I think you'll be ok deer unless u plan on going faster and there is no problem with wanting to go faster.

 

[Nyconn18]

big ups for that time, really impressive with that turbo IMO. And i think e-town did change it cause my one boy on fri. was hittin 12's all day and they didnt kick him out... Hope eveyones at mitsu day!

 

[destruckeclipse]

That is great, this gives me a base for what times I can run with this sucker.

Its possible with the power the car makes, if I drive it perfect. ALso lets not forget that is on Pump, on C16 the car should have enough to run faster than 11.59, once again if I can drive it right. I would rather just cage the car anyway, since I drive it everyday and its just safer and once I hit the best ET I can get with boost, I will do direct port or maybe bigger turbo.

Awaiting that updated new time.

Anything yet?

2g ECU's have 16 degrees max timing at WOT, unless the timing is advanced by something else. ex. DSMLINK.

 

[WhiteCloud]

Hmm, I'm not sure how I get 19 or 20* near redline with my SAFCII and pocketlogger, then ...I assume he is using the same setup?

So did you ever take the car back for some more passes?

 

[CanadianTSi]

Obviously you have no Idea how the S-AFC works....

 

[DSMPowerTSi]

I went back to the track but didnt run a better time. The track conditions werent good at all. I managed to pick up 1mph in the 8th on one of the runs but I missed 4th because I was looking at the boost gauge . I'm gonna head back to the track after I take the cat. out

 

[WhiteCloud]

Obviously you're being a jackass for not contributing anything meaningful to this thread. Perhaps you'd like to enlighten us all with your infinite knowledge

So 98TsiAWD, are you saying he shouldn't be getting more than 16* peak timing even tuning with an SAFC? Maybe I'm missing something obvious, but I just don't understand that statement, since the whole goal of logging and tuning is to increase air flow without seeing knock (thus keeping good timing throughout the powerband if you're only logging with pocketlogger).

DSMPowerTSI, sorry you didn't get some better times the other night. Taking the cat out will almost assuredly be good for some extra horsepower

 

[CanadianTSi]

A stock car should see 16 degree's, but when you install an S-AFC and take out a bunch of airflow the ECU adds timing to compensate...that's why people get over 16 degree's.
