Hahn SS/TC hits 12's!
Here's the list of mods:
Hahn 3" CatBack
Hahn Prototype CAI
Hahn/BSR PPC Tuner
To get the power to the track, we used Mickey Thompson ET Street radials on stock wheels.
To get the power to the Mickeys, we used a new clutch we've developed. The stock unit just wasn't up to the task of being a steadily-dragraced car with sticky tires. It's wise to keep in mind regarding durability of the stock clutch...this car's been flogged since it had 500 miles on it, so the clutch may not have had much of a chance with such minimal break in. Plus, if anyone was going to find the limits of the stock clutch, it would be US! No other company so relentlessly dragraces their own equipment in the quest for not only bragging rights, but product development of the highest order.
The 12.95 you see here was the last pass of the night, and the only 12. I reeled off a string of 13.1 and 13.0 passes before nailing this one juuuust right. Funny thing is, it wasn't even my best 60' of the night, so there's def more to be had with more practice. The car was just perfect...I made 7 passes in just several hours, and she didn't even whimper!
My best 60' of the eve was a 1.93. The car is very challenging to launch, even with the Mickeys...when that 330 ft-lbs of torque hits the wheels in 1st, it just wants to break the tires loose...hard! I've been high 1.70's with FWD drag radials, but that was on a car I did a lot of laps in to get there. I don't doubt this one will follow suit!
MPH was decent, but with a mere 13.5 PSI in the Mickeys, I was definitely scrubbing off a MPH or three. A worthy tradeoff for the 12 second pass!
==================
Now, I've been off the forum for a while while tending to what has proven to be the most challenging summer in recent memory. Since we last spoke, I've developed and tested a 600 WHP TwinTurbo C6 ZO6, and been putting out about 620 WHP on our 2.0 Ecotec Sunfire (news on these projects soon too!). My son Adam joined the Air Force, so we are trying to squeeze as much out of his Sunfire as possible before he leaves
I was also off work for awhile, laid up with a bad back, and we've had a rash of equipment breakdowns, employee illnesses, and deaths in families...it's been a #$%$ adventure!I'm dipping my toe back in the forum waters now, and figured the best place to pick up was where I left off...with the TC development. Fear not, things have been happening in this TC arena too, and I'll have more to share very soon. We just wanted to first finish what we set out to do, which was show a TC could go 12's with just an intake, exhaust, and tune. Tires and clutch aside, it's still a pretty impressive accomplishment for a car with such simple bolt-ons! VIVA SS/TC!
So, I humbly request that if you'd like to speak to me about anything OTHER than TC stuff, that you PM me so as to keep this thread clean. Thanks!
