Default New MRC record, 13.1 N/A

Went to raceway park tonight and broke my personal best of a 13.4 with a 13.1 @103.50 .And this is only with external bolt-ons.. Not bad for naturally aspirated!!! We plan on doing a little retuning and trying to break into the 12's N/A with only bolt-ons before my APS Tin Turbo comes in.... Stay Tuned!!

I was running MT Steet E/T's 26x10.5 .... The ECU works great but the reason we never sold them nationally is due to a check engine light that comes and goes... We have installed it in a few customer cars locally and have had great results but we were never able to track down the issue that was causing the light... I will have mine for sale once I install my APS TT so let me know if you are intersted!
Thanks,
Jason

Temp.70
Realative Humidity- 53
Barometer- 29.17

60' - 1.853
330- 5.434
1/8- 8.433
mph- 82.27
1000- 11.010
1/4- 13.191
mph- 103.36


There you go!
I am going to try this week for my 12.9... It was my first time with these tires and I only had 3 passes at the track. I know they are capable of low 1.7's so I should be pretty close to hitting the 12's N/A.....

As far as weight, don't ask!! I weigh 235 and the total with the car is 3520... So, I need to remove the motor or get my 110lb girlfriend to drive if I want to worry about weight reduction!! I only have until the end of September to break into the 12's N/A before I put on my APS TT..... I will go to the track next time we have some cool weather here...
Thanks,Jason

Hey Dan,
Thanks! I am shooting to hit the 12's with this same setup hopefully in the near future! A couple more passes on these tires and I know I will be there!!

Awesome times! What type of wheels are those in the back? Can you spec the size and offset?

Thanks

yea they are weld prostars like u said, came off a mustang so i believe they are 15x8 with a 5 1/2 backspace... The front runners i have access to require spacers and longer studs so I don't run them.. That was actually my first time running the ET's.. PLan on going back real soon and going for the 12's... I'll let you know!!

I don't have a scanner or camera handy but my last dyno pull came up with 261.5 hp @ around 6200 rpm's and 253.8 lbs of tq @ around 4700 rpm's.. This was done on a dynojet dyno.. Not bad for external boltons.. I will try to post the dyno in the near future so you can see the sick tq curve of my setup...

a bit hard to read but it is 261.63 hp @ 6198 rpm and 253.84 tq @ 4850... Obviously the dark blue line is the hp....
Thanks,
Jason
