Corvette ZR1 with minor mods and a safe tune nets 598rwhp

[monaroCountry]

GM has said that any further increase in HP will need a massive revamp of the cooling system, so do your calculations. That the engine can provide this HP on the dyno is not the issue, that is easy enough, but to keep the car in one piece might be more of a problem.

Someone else has said that the ZR1 uses a similar supercharger setup as the Ford GT (upgraded option). Apparently this supercharger is good for 700rwhp. Ive also heard that the cooling system can easily support that 700rwhp.

The cooling system myth that people started has already been debunked. It was originally said that the cooling system cant support a tuned ZR1. The mod above is a tune and full exhaust.

The clutch and transmission is also a proven 700rwhp setup.

The ZR1 has been over engineered. GM used a SC setup in favour of turbochargers because the turbos melted. GM also has one of the best and toughest endurance testing.

The CTS-V with 550hp uses a one brick cooling setup, the ZR1 uses two bricks.....

There are a lot of reasons. Engineering talent was never one of them.

For certain products of the company yes, but there are lots of their products have some questionable decision gone into them. Though if those were caused by the engineers or the bean-counters I can't say...

GTR is the new Godwin!

If you can't say then don't blame the engineers.

Are you saying that the engineers bear none of the fault for GM's current situation?

[RacingManiac]

having to work with their parts when developing our product I have to blame somebody.......some pretty silly design decision were made by somebody....

Are you forgetting the Chevrolet Cavalier? That was just...awful.

[Bleeding Heart]

Well... I don't know if you'll agree with me here

But... Aren't cars like the Corvette suposed to be just fun cars to drive... You'll sacrifice reliability and great engineering for the joy of driving the car...

It's just my opinion though...

[clutch-monkey]

well they're not exactly unreliable, although presumably that changes when you start shoving extra power through them

[Bleeding Heart]

So... what you're telling me is that the ZR-1 engineering couldn't handle the 620 bhp under the bonnet and they should lower the power output of the engine... Am I right there???

[f6fhellcat13]

No I think he means getting more than 620hp out of the engine would make it unreliable.

[clutch-monkey]

^ yep, especially if the cooling system stays stock, that's the part GM said could be the weakest link when looking for more power iirc?
i wonder if people will try air-to-air intercoolers on their ZR-1's

[RacingManiac]

packaging lots of cooling in a road car that makes 600+ bhp, especially one that started out as a car that was not designed for that, is probably quite difficult....just look at how many louvers and vents on the racing versions of these cars....

btw, Corvette IMO is one of the only product that GM actually do proper engineering work on(and spend real money on too). They really treat it as their real halo product and lots of innovations and technology goes into that.....and the upshot is that as a halo product it is an absolute bargain....

I would say their individual engineers are as good as any in the world. If mistakes were made (many were) they would be due to organizational goals and standards. Individually GM has many, many brilliant engineers. However, even brilliant engineers will fail if put in untenable situations.

If the car from factory have's this
Performance figures
Power 620 bhp / 463 KW
Torque 807 Nm / 595 ft lbs
BHP/Liter 101 bhp / liter
Power to weight 0.41 bhp / kg

This numbers are in the engine I guess, so what is the hp and tq in the rear wheels before the modifications?
Since to be that the car loss a lot of power from engine to wheels.
