13.4 @ 108mph, 13psi, crappy 3 years old SP9000 225 tires.

No timeslip, was at drag competition in Croatia. Won
I thought I could go below 13secs, but there seems to be a problem in my car somehwere. I only dynoed 255whp/260tq at 12psi (with stock IC at that time).

 

One day I'm going to start seeing fast street driven rotaries, right?

The best trap in there was a LS1 powered 3rd gen 128mph.

 

13.03 @ 106.6
Stock motor, stock twins
Intake DP,MP, BOV, Peter farrell Purple box.

 

pluto got 127, that is fast

 

It is fast, but is it reliable? I would buy another 7 in a heartbeat if someone could get me 130mph traps with reliability.

 

1993 CYM
Pettit Ground Kit
silicone vac hoses
45kmi original on the car/motor
original tires from 1993

1/8th mi run here in Charlotte NC
60' = 2.01
330' = 5.61
660 ET = 8.58
MPH = 83.999

I think 13.0 or 12s is just a tire change away. The stock tires are hard as a rock and also suffer from dry rot.

 

Went 11.58 at 120mph with the new setup. It was pretty hot high 80's and the humidity was almost 90%. I can't wait to run the car when it's cool and low humidity.

Shooting for a 10 second pass....

 

13.59 @ 115mph granny shifting, on and off the throttle.....the rear-end squats too much even with the HKS DRAG setup......and the tires rub.

 

just ran a 12.9 @ 108 last night. It was 80 outside though. It was freakin hot as hell. I have a dp,mp,PFS,intake. I need to get my front mount and a vented hood to lower temps.

 

stock tires, and a 2.02 0-60 ft time.

 

Temperature 77 degrees
Peak boost reading 0.82 bar (11.8931 psi)
Street tires on 18's (Toyo Proxes T1-S)

60' 2.114
300 5.583
1/8 8.376
MPH 89.90
1000 10.785
1/4 12.804
MPH 112.67

And I did it while spanking a 2003 Mustang Cobra (13.636@106.83)

 

I ran a 12.971@111.92mph back in March. That was on Nitto 555's, stock twins, IC, and suspension. I'm on deployment right now, but I can't wait to get back to the States and hit the low 12's.

 

Went 11.24 @ 123.56 mph tonight. I am going to make a 10 second pass very soon

ET Streets with 15 psi in them. Launched at 5500 rpms. 16 lbs of boost.

 

ET=? how do you like the t-78? why did you get the heltech instead of the PFC?

 

Went 11.29 @ 126.14 MPH with a 1.59 60'. That has all the making of a 10 second pass. Will see if I can do it this week...

 

Sorry for the double post...

Made 5 passes on July 16th.

All in the 11's, all with traps at or above 122 mph. The final pass was a 11.29 @ 126.14 MPH with a 1.59 60'. I did cut a 1.57 60' on a 11.31 pass.

The car is ready to make a solid 10 second pass. Hopefully it will be this week.

 

Those are great times fastrx7man. Finally someone around here that can drive there car.

 

Street ported, Apexi Power intake, Downpipe,
Street tiers(goodyear Eagle F1), stock twins.
Boost was peaking(creaping) at 11psi
60ft 2.35s
1/8 9.2s
1/4 14.035s @ 103mph

Happy with the low 14... but i would had liked to get a high 13
But then again this was my first time at the strip.
Havent figured out on how to make good starts =(
Feelt like the rear was "jumping" on 1st and 2nd gear.
Also when should one shift? I shifted at 7k rpm on all gears.

How low do you ppl think iu could get with my current mods? Below 13.5s??

Dizzy

 

Dizzy, I ran 13.5 bone stock with a *boost problem*! With your mods you should have a Apexi Power FC and you should be running atleast 12.9 ETs. Hell my stock RX-7 has a 12.9-13.0 in it with some slicks so you should be running a solid 12.9 ET on street tires.


Shift at 7K in first gear, ride 2nd out to 8K then shift 3rd at 7500. Also, it sounds like you are getting wheel hop in 1st and 2nd gear. Try launching by bringing the car up to 4000-4500rpm and SLIP the clutch coming out of the hole. Also if you are on street tires GO AROUND THE WATER BOX and don't do a burnout. This will help you.

 

only have an 1/8th local

with a 1.66 60ft, i ran a 7.32 @ 96.59

this was done with a t78 at 16psi on a ported motor and nitto drag radials. i need more boost and et street. i was almost kicked out of the track for no cage. good thing i broke my diff housing on the next run or i woulda been kicked out

 

60' 2.19
330' 5.76
1/8mi 8.7@84.23
1000' 11.30@92.11
1/4mi 13.6@97.19

Running around 7-8lbs of boost(boost problem) and shutting down around the 1/8mi to 1000'. I was bracket racing and didnt expect the car to pull as hard as it did that time.

Can anyone estimate the 1/4 mile time if I would have stayed on it? a 13.2 or so?

 

Did my first runs at atco last friday here are my times ,
Please take note that I am running on half a turbo (secondary turbo does not kick in, after 4500K boost slowly bleeds off), and original engine with 110K miles on it.
