How much power to beat a ZR1 corvette?

[zbrown]

What does a zr1 trap? Maybe 130? A 500whp FD should be faster than that easy enough

It appears that most nicely driven ZR1s are trapping in the 125-130 mph range (with 1.6-1.8 60ft), very few being outliers at over 130 mph. Source: http://www.corvetteforum.com/forums/c6-corvette-zr1/2808968-the-c6-zr1-1-4-mile-and-standing-mile-fast-list.html

My old 2800 lbs ~~435 rwhp FD trapped 126 mph, but with a much worse 60ft, and with much less seat time than the top guys in the above link.

If you guys are right i will beat him for sure, my old ls1 with 420rwhp went 11.6@127 on Hoosiers.   My new setup should be a lot stronger so I'm hoping for good results. 

[zbrown]

Sorry but no 485whp if you are only trapping that

[zbrown]

A true 500whp FD at normal weight will trap more than 130
Trap numbers = real rwhp

Comon now... I was making 435rwhp and trapped 128 sometimes even 129 . 

[zbrown]

Yup exactly ^^

[mattster03]

Oh... nm I thought you were calling BS on Paul.  Now I see the pos above that

It'll be close.  My FD with 565 rwhp was trapping about the same as the ZR-1's at the Mojave mile.  IMO they had slightly better aero than my setup but I had-400 lbs less weight.  I've driven both cars and when TC is active it feels like the racelogic cycles quicker than the GM system. It felt less intrusive under hard accel.

Now if he throws s snout, pulley, E85 and a tune at his you won't stand a chance......

[paul_3rdgen]

^ yeah I'm worried that he might be throwing a stage 1 lingenfelter kit on as we speak.

No E85 here that I know of.

I think you are right, the car might have made ~~ 435 whp at that point.

I did some highway pulls against my buddy's stock 08 z06 and his gearing always favored him on the highway over 100mph. By the time I was at the top of 4th gear he was a few cars ahead.

If it's from a dig you may be door to door for the first 1000 feet but if you are running a RX-7 rear end he will leave you up over 100.

Let us know

What are the specs on the car that you were driving?

Yep, Z06s and their curb weights are tough.
