Arrow C5Z06 (370ci/Race Gas) vs G8GT (TT/E85) *vid*

Traction issues for both cars, watch the 2nd run closely and you can see how bad the C5Z is swaying back and forth.

Got traction much?

Still pretty sweet to see a family sedan with a combo with A LOT left in it run away from a C5Z. Not exactly the easiest feat.

High Compression. 13.7

If this is the same TT G8 that the Procharged G8 raped it really puts it into perspective just how fast that white bitch is...

Nice runs, Z was swaying like crazy. I would have pissed my pants.

compression like that is useful when you have a fully built race motor reving high rpm. All that compression is doing in this car is ruining its streetabilty. Thats the kind of compression that needs octane even at idle or it will ping.

Compression makes up for displacement. Lets you run a much bigger cam without sacrificing as much mid range. Compression and RPM have nothing to do with each other. That sort of compression is just fine on E85. Ive seen that compression run on E85 quite often without any issues. Race gas is over kill IMO.

Not impressed with the high compression, big cam Z06... I would be rethinking that combo...

That 4200 lb G8 just brutalized it....

Shane's white G8 is definitely the monster outta that group.... THAT car is impressive to me...

That c5z would've done better with full bolt-ons.

Same car, same night. I just whored my vids out to Shane so he could make his video (I was the bumb yelling 123 in his vid haha). At least I get a cut of youtube checks for that.

Shane trapped 134mph best.

I understand how that works... but once you start getting passed 11:1....you start sacrificing your ability to run on pump octane for minimal gain. That whole "jack up the compression to make up for the spongeyness of the cam that is way to big for this motor" theory doesnt work. Ive been there... ive done that on one of my numerous motors. I personally prefer 10.5-11.0 for an N/A motor. Compression is a bit over rated in the modern era. Back in the 60s... compression and cubic inch were king...

Its pretty clear that the setup in this z06 isnt very good. Like HIO said, a full bolt on z06 would have done better.

Ive seen different, several times. Ill just skip the argument and agree to disagree. As for pump gas, that's just a choice. Like ive said plenty of times around me E85 is everywhere making it not a problem to run or "hassle". The z06 has stock head cast, and stock LS3 IM. It runs like it should IMO. IMO its running like it should.





what does this G8 trap anyways?

supposedly this is a mid 120s trap G8. It shouldnt take much for a z06 to get to that. Even if this car has stock head and stock intake, it should be plenty

In that case, i agree completely. Goes to show you how usless dyno #'s are. This car dyno'd 5xxwhp i believe
