measured at the rear wheels on dynojet. we disconected the prop shaft to the front diff.

 

we have not run it on a road course. my overall impression of the GTR is that it will take an average driver and make him faster while he enjoys feeling faster. the car is very forgiving.

heinricy has not driven it yet.

the V is a sedan, so no real comparo there. the zr1 is faster and performs better in almost every category stock vs stock, modded vs modded. however the average driver like me is going to be faster in the GTR. the zr1 requires a higher skill level for it to operate at the top of its performance game.

the ZR1 with mods is really fast from 80-180. we have seen 0-186 mph in 27 seconds. that is over 9 seconds quicker than a stock ZR1.

the GTR is going to have to get closer to 700 rw hp to be able to muscle with some of the big boys over 100 mph.

 

I got ya. I honestly dont understand it either. You would think a 60-130 pull would be quicker than whats being reported. I just know my car feels fast as hell from 0-60,70,80. Maybe a few things to consider.
1. Is the person that is driving the GTR in R mode all the way?
2. Is the car in the right gear for the speed or when doing the 60-130 pull is the car hunting or searching for the right gear?

I havent timed a pull in my car to really see what it does. Maybe when the weather gets better here i will do it. The way I would do it would be all 3 in R mode and then switch it over to manual mode so that I could shift it. Probably 3rd gear starting out at 60mph would be the right gear I dont know. I will get my G-tech out and do some runs to see whats up. I can do it stock and with a Cobb tune stage 1 to see the differences

The AWD isnt really a factor and causing drag because at that speed going straight the bias is pretty much all to the rear.

 

I agree with you there. There does seem to be a gap of 3-4 mph on the traps but there is also the same deal with a gap between dynos to with a car doing 390- 430 stock on the dyno

No one that I know of has done any worthy weight reduction because honestly there really isnt much to reduce. Other than what you said about seats and tires I dont know where else to reduce weight. Problem with tires is going to a non-run flat that there is no tires made out there in the sizes we need them

 

Hey Hennessey kinda off topic but the guy that transports cars for you delivered my GTR about a month ago. He is a Black guy with a Duelly truck and a covered trailer. Very nice guy he gave me your card and brochure about your place and tuning. He had a Black convertable Viper also going to you he said for tuning.

 

There are plenty of ways to reduce weight. The seats are easily a 100+ lbs reduction on their own. Just going to a PS2 or any non run flat is 20lbs. Then a straight cut exhaust could be worth as much as 50-60 lbs. Then the rear seats, battery etc. etc.

To guys that are trying to go faster, that is the first thing you do to utilize the power you already have, but no one seems to ever mention what they took out of the car.

 

I know about the PS2's but most that have tried them done like them and the exhaust I only know of 1 maker that makes a straight through design and people dont like them either(I kinda like it though because of the weight and also the straight design should help with power because of no bends too)
