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!!

what tires were you using and also how is that perfectpower ecu working out for you?

 

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,

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.....

 

nice, like you said you should have some left just in the 60'. It should be very close if not there. Good luck. whats your race weight?

 

that weather sucks

wait til the winter to bet some great N/A times I see 12.8 at 105 happening

 

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

 

congrats... great time...

Keep going...

 

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!!

 

here are some pics

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

Thanks

 

15x8? inch weld prostars

its what i have... they weigh 10-12 pounds for the rears

but i have the front runners, i guess you cant run those with yoru brakes... I had to grind mine to fit.

 

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!!

 

Wow! Do you have a dyno sheet?

 

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...

 

just found it.. here ya go

 

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
