99 4V vs 01 2V???

[SPoole]

I have a 99 Cobra with a Novi 2000, and my friend has an 01 GT with a turbo. Both cars have similar power levels, around 600whp, but they have a lot of differences.
Engine:
Cobra is a built iron block 4V with Novi 2000.
GT is built aluminum block 2V with turbo.

Drivetrain:
Cobra is a T45 trans IRS and 4:10 gears.
GT is a T45 trans solid axle and 3:73 gears.

Suspension:
Cobra is full suspension, coilovers, cross member, frame connectors. This car is setup for road racing never even seen a 1/4 mile track.
GT also has full coilovers, and crossmember and not sure about frame connectors.
Both cars are running 315 R compound tires on 18" rims.

Interior:
Both cars stripped from the front seat back, and both have racing buckets, but the Cobra also has the extra weight of a roll bar.

So the question is which car do you think would be better in a run, and I would also like some facts about the weight differences with the iron block vs aluminum, 4V heads vs 2V, IRS vs solid axle, and roll bar.

Ideas, suggestions, facts???

should be a decent race

i say pull your balls outta your purse and run him...AND GET VIDEO OF THE RUN!

Lag from the turbo will hurt the 2v and the other car having the same amount of power without the lag should put it ahead. Also the 4.10 gears wont hurt either. My money would be on the supercharged car, given both drivers are equal.

Are you going to record this? Should be a good race! :thumbsup:

 

[evo connevo]

hmm, longer the race...the better the odds for the gt imo

 

[SPoole]

Not sure if we will film it, but I agree the longer the race the better chance he has.

Both are S/C technically, but I will agree the 4v Centri powered should win.

I think whoever jumps out first will hold off the other. I like 4 v heads for top end.

Centri and turbo are not that far apart as far as efficiency goes for F/I...if I remember correctly?

Thanks for the input so far..... Anyone know about the weight differences?
I am curious how much more my car weighs than his.

Not talking effeciency, but the turbo has to spool up where the S/C is pretty much instant boost.

Not if it's a centrifugal s/c, which relies strictly on rpms. Which means it also lags. Op from what you are saying, this race should be a really close race.

99 Cobra waas the lightest(unsure of 01) of the New edge Cobra's 3430 stock.

With a cast iron block you are adding 80 pounds..maybe? I found #3429 for the GT stock.

With all the mods you both have it is a tough call. At 600 rwhp a slight weight differences are probably not a huge deal.

:dw:

Sorry dude..most people forget that

Ahhh alright. Thanks.

Centri 4V should pull up top especially if the 2V has stock heads.

 

[SPoole]

Yes 2V stock heads and cams, 4V has ported heads and Comp Cams.

I actually think I have more lag than him because I will need RPMs for boost and he will start getting it as soon as he has WOT and load. I have ridden in his car before the bottom end build and he has very little lag.
It should be close but unfortunately due to weather and his motor not being in the car yet we will not be able to find out for a while.

I think the 01 GT will make a bit more power and will also have a weight advantage so as long as both drivers are close to even I'll have to pick the 01 GT for the win.

01 GT FTW in a close one.

its a novi 2000 not a positive displacement like a eaton/kenne bell/whipple etc... he won't have max boost untill high rpm's.

if ya'll run from a dig it will be close.

roll race from 45-60mph and i say the 2V takes the win.

the GT owner doesn't even have the motor in yet? :bored:
