Help good numbers for a 12.60 pass ?

[Faspace]

I took my Buick to the track tonight for the first time
42 pound injectors
20 pounds of boost
93 tt chip
340 pump adjustable regulator
Built trans no brake
275/60 Mickey drag radials
780 o2s about half track dropping to 760 no kr
Just don’t know what to expect I feel my mile per hour is low
It is a 93 octane chip but I had a full tank of 110 just to be safe
12.63@103
1.64 60”
7.92 1/8
What are your guys thoughts thanks for the help in advance

I think your mph is low. When I ran my car 20 years ago, it ran a 13.06 at 106.

Do you have a hot wire kit for the fuel pump? Do you have the factory 342 gears?

That is a great time slip for your first time out!

You are very smart to have 110 gas, and you can increase boost at a pound or 2 at a time, and you will see MPH increase.

I "assume" the turbo is stock.

Like was stated above, get a hot wire kit for the fuel pump, and I would bump base fuel pressure 3-4 pounds to assure adequate fuel at the injectors.

Bet you will do better next time at the track!

Yes it has a hot wire kit it has valve springs and it was an open down pipe

Get a wideband and logger. Anything else is just guessing. On logs, first thing I look at is boost, KR, RPM, duty cycle, and fuel pressure. Most likely trans slippage or wrong fuel/timing for the chip/boost/gastype combo. Make sure KR sensor is attached. The 93 chip probably wasn't setup for fueling a race setup. Lock the converter with a paperclip and switch to the ALDL would help the MPH. I used to run 104 on pump 93 E10 at 16-17 psi on a stock setup TT 5.7/93 chip. Years ago I remember the trick to crank up the base fuel pressure to like 50+ and run way past what injectors were supposed to run for a given chips fueling. Even if you get the 5.7/6.1 TT chips and powerlogger, you only get like 8 fields to change. One of the reasons so many go for the XFI Sportsman,TT GN ECU, MS3, or Holley EFI etc. There really is no comparison to having a real engine management system vs 1980's technology. I'll never go back to a stock ECM setup.

Go with at least translator plus or other tuning device to adjust fuel /air delivery.

Do you know what your rpm was at the finish line? What's your 1/8th mph? Mph is low. You didn't happen to lift early?

780 o2s about half track dropping to 760 no kr

i dont like this at all.the 110 took care of the kr but i would advise looking at fuel pressure for a 1 to 1 rise.

 

[Mr.Spool]

12.63

i like this and your 1.6 60ft.

usually putting 110 in the tank with a 93 chip richens it up and usually loses power,but throughout the run not just up top.110 will handle more timing and boost but usually needs more timing than 93 to show power increases.please look at your fuel pressure and or give it more wot fuel from the tt chip.

hmm,that is your right but i have seen some really fast great running stock ecm cars.

 

[Mr.Spool]

Go with at least translator plus or other tuning device to adjust fuel /air delivery.

if he has pressure and octane the tt chip that he has will give him all the control he needs.there are 8/9 sec stock ecm chip cars that run a maf sensor.

 

[Mr.Spool]

Just don’t know what to expect I feel my mile per hour is low

the high end mph on a stock turbo is around 108/113mph at full weight.on a 1.5 60ft 12.0 ish can be had with 108mph

 

[Pronto]

Do you have a hotwire kit on it?

[Pronto]

Missed that. So a good fuel pressure test is in order then.

 

[Faspace]

Sorry I forgot to mention stock turbo and it has a maf translator on it also

 

[Faspace]

It would pick up a couple tenths and a couple Mph every time I would bump the fuel pressure right now it is at 40 psi with the line on at Idle Do you think it could stand to have more fuel pressure should I keep bumping it up until it quits picking the car up

 

[TurboTGuy]

Base FP should be 42 with line off.
