Yeah but its a whole lot more consistent and doesn't break. AMS really set the bar for fast street cars in the 1/4 mile, I hope someday they decide to get into mile drags too. Its not that safe but I bet with that kind of launch they could hit above 250 with the right gearing.

funny thing is, the launch doesn't look that dramatic. medium revs, a brief chirp, a split second bog and then away it goes. but it doesn't launch like the fast 1/4 mile evos of years past from the same shop. but that thing is moving. any car putting down that kind of power and hooking up is seriously going places.

I think standing mile races are very interesting... Cars like the TT Ford GT that dont boost until 6000RPM and then break loose at 140mph @.@

But yeah, that Lambo would eat the Evolution Mustang through anything that has a corner. I guess I don't really see the point in spending all the money on a drag car like that when you could put $20k into a foxbody and get the same ET (if not the jaw dropping MPH).

I love watching AWD cars take off when they are launched well. Wait.....wait...GONNNNNNEEEEEEE I agree with the general amazement at 10 and 140 from the GTR and the like. How's this for some perspective on the progress of psycho engineering in cars? It's an awesome feature

Notice 4 of the 6 generation leaders are turbo...I might see a trend?

I love boost.

Hmm, John shepherd did ams's trans. Is anyone else pushing these transmissions as hard as you guys? Surely there's a way to make it hold. Then, slicks

[JB]

Yeah we have our own in-house guy do almost all of our tranny work. Its the common problem with cars like this, you break something so you upgrade that, then you break something else farther down the line so you upgrade that, and so on. I guess we are just breaking things till we figure out what all likes to break.

I wouldn't be surprised if Shepherd could build it better since he has been doing transmissions for so long, maybe they will go that way one of these days.

Slicks will be stupid. If they can ever put down all the power in 1st and 2nd gear the race to run 7's in a non-tube chassis street car will be ovah...

[93redfox]

7's in a non tube chassis street car you say? (I think this one is just back halfed)



quick e.t.'s were 7.80s Drag Week '09. cooling issues have since been fixed lol, and it also did 241 at the maxton mile. not bad for an old bird (pun intended)

Eric Yost made his second appearance at Drag Week in Jeff Pearley's Firebird. Jeff is the former crew chief on Greg Anderson's dominant NHRA Pro Stock team. The Pontiac was a solid 7-second player, but it was a long week for the him, especially when he grenaded the transmission at National Trail. Fellow racer Rick Prospero had a spare TH400 and offered it to him, but it had the wrong case, so he gutted the good one in the pits and put the parts in the Firebird trans. With the help of a big group of fellow racers and presenting sponsor Rick Johnson of Gear Vendors, he got it together and made the drive to Muncie on time-and only needed a 14-something pass to win the class. But Eric went for broke . . . and broke, coasting to a 15.38 and handing the win to Mike Roy's Monte Carlo. That's gotta sting.


Combo: With a 4.125-inch bore and a 3.75 stroke, the ex-Lingenfelter engine uses what Eric called "old" cylinder heads force-fed tons of air from a pair of 76mm turbos controlled by a BigStuff3 system. The trans is a TH400 backed by a Gear Vendors overdrive, and the former Steve Grebeck chassis uses ladder bars and big Mickey Thompson rubber. Check out the cardboard airscoop they made to prevent overheating on the road.

also, this one is tube chassis, but epically awesome in that it's still driven like a street car:

Engine builder Mike Moran told him to change the lifters, but Larry thought they would be OK. After all, they'd only been in this twin-turbocharged 555ci Rat motor for three years. And it had only had to deal with thousands of miles of street driving on Drag Week for three years, multiple 7-second passes, and some occasional street driving. What could possibly go wrong?

Larry would be plagued by those old, tired lifters on Drag Week when he ate one at the second stop in Michigan. He fixed it, then had another failure in the middle of nowhere Michigan or Ohio, literally in the middle of a cornfield. Two lifters were toast, so he wired them up out of the way and drove to the next checkpoint on seven cylinders, cell phone rumbling to get new parts to the next destination. They got there, he swapped them, and his Drag Week legend continued undisputed.


Winners Doc Fox, Michael Roy,...

All we can say is 7.25 and 204 mph. Granted, they didn't occur on the same pass, but the fact that either of those numbers came out of a car that traveled 1,000-plus miles, while we watched, over country roads and interstates that many 12-second muscle cars would have a tough time traversing . . . what more can we say?
For the second year, Larry Larson's Chevy II is the baddest-assest, most awesome, no-doubt, no-holds-barred Fastest Street Car in America.

Combo: Larry's bullet displaces 555 ci and uses a Lunati/Oliver/JE bottom end and Dart 360 heads. Mike Moran built it and used a pair of 88mm Precision Turbos mounted to Larry's own headers to make all that power. A five-speed Lenco CS2 transmission is just drop-dead cool in a street car, and Larry built his own 9-inch rearend housing-and in fact, the entire car-at his Larson Race Cars shop in Oak Grove, Missouri. The tires are 33x18.50 Mickey Thompson ET Streets, and Larry doesn't change them when he gets to the track. The same tires used on the road are also used to run 7s.

240mph in a early 90's Firebird...balls!!

[93redfox]

yah, nuts.
