I have not seen that car in nearly a decade...

Anyways,
Power will be improved over when it was new - has one of our upgraded Wonder Bars to force-feed more air to the turbos

Hard to say if it would actually hit 205 without the Callaway AeroBody and the fact it is a convertible. If it were an AeroBody Callaway Coupe, no problem.

I hope this helps - you buying?

Yeah, I am in the market to buy one. Low miles, show condition. One of the reasons is, that I can get a vintage car certificate for it now, since it's rare and the 1st model year of this car car is 1984. Reg+insurance would set me back only around US$200 annually. But it seems like I will end up buying a C4 ZR1, since there are more of them available in nice condition.

That was a B2K. But it was also a convertible and if I recall, had the AeroBody

The Big WonderBar however, adds power and will in turn, add mph

Best of luck with your search - there are PLENTY of nice Callaways out there however, limited when compared to other C4s, that's for sure!

Pick up a copy of Corvette Enthusiast from a few years ago - the Article, Son of Sledge, and the King will give you a great comparison to the Callaway and ZR-1

Would you know which month/year of this magazine that would be?

The 1989 B2K had, what, 389 HP? The last ZR-1s had 405 HP and essentially the same body and they topped out at 186 MPH. So... yeah, no stock B2K would ever have done anything close to 205.

At 1st I automatically thought, that the engine has been modified. That was my 2nd question when I contacted the seller. I was surprised to hear "it's all 100% original". Then I said, it's not possible, he said it's 100% correct. I asked if this car is then faster then the current ZR1, answer was "about as fast". Even dough I am in the market to buy one, I would never buy it from such a seller. I guess, there are probably more issues with the car, if he can't be honest about such obvious and easily verifiable facts.

The b2k did have 575lbft of torque which is where the pull comes from. The ZR-1 had 405hp.

I do agree whole heartedly that a stock b2k can't do 205.

Why is it, when someone compares a ZR-1 to a Callaway, the highest hp is always quoted?

Why not quote the 375 hp from a comparable year?

Also, Callaway Corvette had 403 hp in 1991. Truth of the matter, it actually had more

I only quoted the highest ZR-1 numbers to make the point that if a similar car with more power can only manage 186 then that car would certainly not do 205.

Don't get me wrong, B2Ks are great. Their fatter torque curve gave them better real world performance than a similar peak HP ZR-1.

Actually, we were able to use 6th gear for top speed, as a result of having the massive torque output

ZR-1s topped out at ~180, and was done so in 5th

Yes, very true. Gearing falls under the general category "all things being equal" except I didn't meant so much literally equal, though the gearing was probably identical in this case, but more ideal. Because the L98 HP peaks at a lower RPM a taller gear works better for it.

Regardless, the ideal top speed of any vehicle comes at the engine's peak HP. If the gearing does not allow that then some speed is being left on the table.
