ZR1 in the 9's!
 

America was made just a little greater after Lingenfelter modified the ZR1.

Here is what a bolt-on Zr1 is capable of with a good driver, BTW I know they made at least (3) 9 second passes that day. Enjoy.:cool:

How was the trap speed and any idea whats done to it?

The car ran a 145.74 mph trap speeds. The car also made 2 other 9 sec. runs earlier that day trapping 144 mph. The car has stock: heads, cam, exhaust system, clutch, rear end gear and transmission. The mods include:

- LPE 8.5” diameter harmonic balancer – 11 rib
- LPE 2.60” diameter supercharger pulley – 11 rib
- Lingenfelter S&B air filter
- 4” diameter air intake tube with mass air sensor
- Ported stock throttle body
- Intercooler supercharger inlet modifications
- Double capacity intercooler heat exchanger
- Larger capacity intercooler reservoir system

The car is putting out about 200 rwhp over stock power levels. Dynoed 739 rwhp/740 ft-lb rwtq.

Another plus is that it runs the stock cats and would pass emissions testing.

Not to shabby in the 1/8 mile either, nearly 115 mph in 6.39 seconds.:D

That is an unbelievable run. I love that ZR1

wow nice set up and numbers! ;) Where did you run that car in Houston without getting tossed off the tracks? or was it a Private Rental?

Never mind, I see it was Maryland. Sorry for the previous post.

Impressive runs. Are those drag radials or slicks?

Wow that is sick.

Nasty...Wait till they go internal on one of these or even turbo:eek:

Wow....

Drag radials.

I watched that run first hand.:)

Impressive!!

Such mild modifications! WOW

Seriously impressive!
