142mph 1/4 on stock shortblock L33
This thing is AWESOME, it was posted on tech.
The exact motor in that car holds the stock shortblock LS record in a 2600 RX7, 24.5lbs of boost and 855rwhp @ 8.67/167mph
142mph on junkyard 5.3 ..... - LS1TECH
Since so many people complained about my rx7 being so light, I built a 5.3/76mm daily driver car to have some fun with and be a great sleeper. It's a 1985 ford LTD with 6 mufflers and weighs in at 3700lbs with a whopping 2.73 gear in the rear. It's just a driver, not a race car by any means. I drove it 3hrs to another city for their true street race and made a few passes, this was the first passes on the car ever then drove it home in the rain. I was running it on a small drag radial, 255/60/15 as the car won't fit a bigger drag radial.
10.09 at 139.97 mph on 17lbs BOGGING off the line when I left really soft, just a 1.71 60ft, just leaving on the footbrake. I tried to leave harder on another pass and it went 142mph, but 60ft wasn't good. We still haven't leaned on the car, still just conservative, I think we have around 100rwhp more to throw at it.(especially with it open downpipe vs the 6 mufflers and with it leaving on the transbrake and in boost) The motor had 100k miles on it when I got it and we have about 5k miles on it with the turbo and LOTS of hard street miles and racing.
Once we get the slicks on it and more passes leaving on the transbrake plus turned up it should get interesting. At least this time nobody can say it's a light "race car" (even tho I drove the rx7 over 5000 miles last year, it's a "race car"). Also this is thru some 3.5" procharger intercoolers, I need to get a real intercooler and/or some water injection, I was seeing 200+ IAT's!
We did hide the setup quite well, which confused A LOT of people at the track!

The intercooler is under the car in front of the trans. Like 7 pages into the thread, there is a really nice custom made 32 gallon fuel cell in the trunk that is always full of E85......its packing 3 Walboros, lol.
