10 second ZR1s

Very lairy cam... sounds like my Cobra replica. In addition to the cam, it must be running some pretty scary boost for a stock bottom end. That engine is on borrowed time with stock internals. So are the half shafts and diff, if they're also stock.VERY impressive though.

also worth noting that a guiy in the US recently put his C5 into the 8 second bracket (8.85 i think) and he is still running the IRS setup......
Chris.
It is worth remembering that the Z06 and ZR1 both use the same Tremec 6060 transaxle.
The ZR1 uses a close ratio gearset so that it reaches it's top speed in 6th gear. In the Z06, 6th is a cruising gear that gets you 40mpg on the motorway, but 5th is what takes you to top speed. Anyway, what I am saying is that the ZR1 has 638bhp and mamages just fine on effectively the same drivetrain as the Z06. Both cars have torque management programs in their ECUs which even when traction control is switched off, will cut in to save your expensive parts if it detects too much wheelspin or wheel hop.
LG Motorsports do a bunch of drivetrain components - I am sure other aftermarket tuners do too.
It seems that for their track packages they offer a carbon propshaft, uprated couplings, uprated clutch and remote clutch bleed kit.
No change to the driveshafts or transaxle. It does seem that there are alot of cars out there running 700bhp plus on stock transaxle.

Katech who build the factory Le Mans winning race engines do specify gearbox upgrades by RPM Motorsport for their most extreme "Track Attack" packages which make over 585bhp. Details of what RPM do the the transmissions are spcified on their website:

RPM Transmissions are used by Katech and Lingenfelter amongst many others.

Rockland Standard Gear do a "Tranzilla" transmission to handle extra grunt too.

Of course utilising the 6L80E auto would work well on a drag strip - they are strong and you can customize the shift points with FAST control boxes and flappy paddle kit. Much faster launch than a manual too!

My C6 suffers from wheel hop quite badly, which is a little irritating I must say. JenkinsComp said:

Any idea how much power the stock 6L80E can handle reliably? The old 4L60E was only just up to the job of the stock torque output on the C5. I've never driven a 6L80E with paddle shift... are the paddles responsive and can it be used as a true manual and be forced to hold each gear at both the low and high end of the RPM spectrum? Would've been nice if the ZR1 had the option of a true F1 style box ala BMW SMG/Ferrari F1 (as in 360/430 F1).The 6L80E can handle more power than the 4L60E but as to how much...I wouldn't be worried about sticking 600 horses through it.
You know it can deal with 450 without a problem so 30% more should be OK! The 4L80E's have been around for a while and those are what people are sticking behind the LSX blocks making serious power. The 6L80E is similar to the 4L80E except with 2 more ratios and more electronic control possibilities.
I drove a Corvette C6 Convertible with the stock 6L80E and also an Escalade, the upshifts were slow to respond to the button, downshifts better. With the FAST gearbox control unit, you can program the shifts to be as fast and responsive as you wish - instant.

RPM built 4 speed autos have taken some MAJOR power in the US. Try twin turbo LS7 (over 1000bhp) power! lolYou know it can deal with 450 without a problem so 30% more should be OK!

also a guy has run an 8 second pass (8.85) in the 1/4 using a 'glide and retaining the IRS!
would be really nice if you could get the 6 speed auto to give you FULL control of the box and have paddles. would make it a 6 speed sequential that can handdle BIG power......
