Just out of curiosity which computer are you using? If your wastegate has not been ported, I find it pretty amazing that you can maintain 13 psi of boost. I sure can't. My guess is that you can run mid 12's on street tires with a good launch (60' time at 2.0 or less). It's very hard to tell someone what they might run because it greatly depends on the driver. If you've never drag raced this car before I would say you will most likely be in the 13.0 range. However, your car is definitely worthy of mid 12's.

hey silver,
i still have the stock ecu and i have not ported my wastegate....
my car keeps psi steady up to 15 pounds no prob...i dyno the car at 12 psi and dynoed at 287 at the rear wheels but i havent had the chance to dyno the car at 15 pounds yet...but maybe next friday i'll let you know how that goes....i have only tried my car at the track once...and i ran 13.6 at 10 pounds of boost but i still had the main cat on....i was runnin nitto's drag radials..my sixty then was 2.1 pretty shitty but it was my first time there so i was pretty happy i just havent had the chance to try the car with this new stuff and this much boost so i hope i can do at least a high 12....
thx

with slicks, consistently low 12's and high 11's--so if you can drive you better put on a roll cage...

most importantly--look at your 60' times, you should be at the 1.5 or faster...

goodluck

under 1.5's is pretty optimistic. I would say if you're in the 1.6-1.8 range you are doing well. It would take more than 15 psi to get in and below the 1.5's

Please tell me your stock ECU is remapped.

Sorry to tell you that you only have a metter of time before your engine goes - especially if you're running stock ecu that's not remapped. Maybe I'm wrong though since you put some money into the fuel system. With those mods I'd say 12.5 or so on Drag radials.

Your car is a low 12 second to high 11 second car. However, that will not last too long since your are running with the stock ECU. You are taking a huge risk on blowing your motor. For right now lower your boost and upgrade your ECU as soon as possible. You have a lot of great mods on your car and the next mod should definitely be an upgraded ECU. There are many great ECU's out there. For example, Power FC, Pettit Racing, and a Haltech.

What is this GREEDY I keep hearing about? Money isn't everything, you know...

Hey guys,
i got myself the power fc.....=)
but i have not tune it yet.....so it will be a while until i get that working......cause im gettin rid of my stock turbos and gettin the t-78 and street port my motor hopefully within a couple of weeks .....so it would be a waste to tune the ecu with the stock twins right???? cause the fuel maps wouldnt be the same....
so i've stopped my rex for the winter and its gonna get worked on for a while........
but my best time was this on the stock motor and stock twins runnin 14 pounds of boost on nitto's 555....
R/T .654
60 1.882
330 5.259
1/8 8.283
1000 10.788
1/4 12.83
MPH 105.65

this was at an elevantion of 4700 ft....in Salt Lake City,Utah...
so im assuming it will do low 12's in Cali....hopefully...

Not bad at all. Good 60ft time. However where do you have you boost gauge tapped into? Also what boost level does your PowerFC say you are running. I'm just thinking that your time & mph doesn't necesarly reflect 14 lbs of boost. You only need high 200s in the hp department to pull that time/mph. Either you aren't running that much boost, something is wrong, or that elevation is killing you! Like I said not bad ... good 60ft time.

Alx7

hey spyfish,
well during that run i was still running the stock ecu.....but that was the last time i ever run that high of boost....
i just barely got my power fc but i have not put it on my car yet...
cause im gettin the t-78 put in my car , sometime next month so i think it would be a waste if i spend alot of money tuning the POWER FC if im gonna go single ...cause the fuel maps would be completely different right???????if thats the case i'll just wait til i put the t-78 .....
both my boost gauge and my avc-r said i ran 14 pounds....
i think the elevation here is killin me... cause theres this RX-7 with a big t-88 here only being able to run ...
11.20 at about 115-119 mph....and his sixty foot is 1.5....so im thinking is the elevation.....
i would like to take my car to cali..and try it at sea level someday..
do you think i would do better???.

Well, Pluto is one of the people to bring in on this conversation, because he and Ari run in CO every year .... I know Ari does and I am pretty sure Pluto does too. You need to get him to compare and contrast the ETs at high elevation. That time of the T-88 car sounds a little slow, but I don't know the setup of the car. I think you will do better at sea level because your turbos aren't working as hard to maintain that boost pressure . . . wait you have a AVC-R ..... anyone know if the AVC-R does boost control by relative or absolute pressure?

I think you need to be running the PowerFC regardless, because it is way better than that stock ECU. Is the stock ECU remapped? I really hope so, else you are on the tight wire with your mods. You are correct the maps are going to be different between the sequential twins and a T-78.

Just slap that Power FC in your car already. It's extremely easy and will only take a few minutes to install. The Power FC base map is made to make an FD run really rich. You don't need to tune it right now, since you are going with a single turbo setup. You are much better taking off the stock ECU and putting the Power FC in right now.
