as you all may or may not know i unfortunately inherited my brother's car back in 2005 when he passed away on a motorcycle accident. Since then its been a little difficult to really get motivation to work on the car and all but with much help and support from family and friends i started really working on the car again this year actually getting the car to its full potential.

just wanted to take this time and share the latest updates since Vegas 2007, it was good to meet a lot of you over in vegas this year and i appreciate all the kind words about my brother and the supra. the car at that time was tuned by Justin Nenni running 485 rwhp @ roughly 16.5 psi on pump.... the car actually made 527 rwhp @ 19 psi pump but was running lean and my injector duty cycles were at 90% per the AEM... , i had problems on the track with traction due to the zeal super function suspension being way too stiff as supranick can attest.... a 16 kg/mm spring is just not going to cut it for drag racing haha.

since then ive wanted to address the lean condition and suspension so this past week i finally had sometime to take the car into Creative Car where supranick works to do the whole fuel system and swap out the rear springs for softer springs.

the results so far on the dyno were awesome

car is now making 514 rwhp / 442.17 rwt @ 17 psi on 91 octane with a lot of fuel to spare surprisingly, i unfortunately could not stay for long as i was on my lunch break so i had to stop at 4 runs total

the car is scheduled to go back tomorrow night at dynoxtreme to do a c16 tune and after that i can officially say the car is finished, ill post the numbers for tomorrow.

And while im at it wanted to give my big thanks to everyone that helped me make this possible.

Hold on tight guys. Brian took it back to dynoxtreme today and put down such an impressive number, that i dont think Mike ever made such power out of one of his cars. Brian will fill u guys in tomorrow along with proof on paper and video! :evil2:

Mike would be proud of all Brians accomplishments thus far.

thanks guys i appreciate all the support , i was actually gonna post this yesterday but sarkis accidentally gave me the wrong dyno file

final numbers are 609 rwhp / 541 torque @ 22 psi on mix c16 and 91 octane fuels

why mix? i actually had problems burning straight c16, Justin was explaining that on small piston motors, the leaded fuel is harder to ignite than regular pump gas. Advancing the timing to pre-ignite the c16 worked but produced less horsepower all across the boards. Mixing the fuel yielded larger numbers than straight c16.

heres the graph, the big dip on th big run was actually because one of the straps came loose under boost, haha.

this shows both the pump gas curve from a few days ago versus the race gas curves.
