Building A Domestic RWD V8 Roll Race Monster

[greasy]

They should be identical if they are putting down identical power...

What should be identical?

The race.

You are telling me a 650 RWHP FI car with an auto going through a 4K stall and a 4.56 gear would be the same on the highway as a 650 RWHP FI car going through a 6 speed and a 3.55 gear???

I thought we were talking about options on the same exact car.... Why don't you just get to the point? Are you confused about the outcome of a race or something?

 

[Turk]

And to answer your question, the stall is meaningless but we would actually still need more details. If the automatic is a 6 speed, it could still pull out a victory against the manual, if it's a 4 speed, it's fucked.

I did get to the point in the first post If you had to build a highway monster out of a domestic V8, what would you build? You said you would buy a C6Z.......still a ton of options out there. Entertain me......

Do you know how to have fun or does everything need to be an argument with you? :lmao:

Twin turbo Ford GT.

With 650-700 blower or turbo I'd stick with the mustang stock auto and stock 3.15 rear stock converter, or an fbody turbo with a 4l80 and a 3.05-3.30 rear gear and a fairly tight converter 3k or less stall

A turbo with a big stall will not have as good of a top end due to converter slip

Well if I had to build a car from the start, I'd probably get a C6Z. I'd have to investigate as to what makes more power, S/C or Turbo and which one builds power at higher rpms. I'd also get a cam that shifts the redline higher and builds more power at the top of the rpm band. In the C6Z, I think the rear end and trans gears are really good from the factory for roll racing so I'd just leave them alone.

There we go!

You'd stick with a 4 speed automatic? Those things are slow as shit once you get into third gear, you'd get roasted by something with less power and a 6 speed+.

Not the ones I've seen, wills car pulls pretty good, Eagles 3 speed did pretty well at the half mile as well

What numbers were they running and with what power? My guess is that there were cars out there with considerably less power running the same mph in the 1/2.

 

[1quick]

I honestly don't know what power either were at I was thinking eagle did 179ish

 

[Mook]

I think Dan did 174ish. I remember him saying the car was basically topping out

Interesting. I mean, you can definitely make a 3 speed fast, just would be faster from a roll if it had more gears due to power magnification. There gets to be a point, though, where you reach so much power that RWD won't hold it anyways which is why the lambos and GTRs dominate everything.

 

[Mook]

I miss that car. My neighbors definitely dont.

I don't know that much about the 6 speed manuals but I'd imagine you can't use all 6 gears under full power most the time the od gears are weaker, I know in the Mustangs with autos they only use the first 4 under full power

 

[Turk]

Not sure about American cars, pretty sure you can on imports though. My 6th gear is used to top my car out at redline.

 

[Ear Rak]

With a good tune, t56 guys can use 5th. 6th is risky territory, depending on your tune and gearing.

Well technically speaking, F=MA so weight matters just as much from 0 as it does at 100mph. The difference is that aerodynamics doesn't matter at all at 0, and a lot at 100mph. Unfortunately, power and weight are a lot easier to change/upgrade than aerodynamics.

I worded that poorly. What I meant was aero start to matter more than weight at the triple digit speeds we're talking about.

 

[Typhoon]

Twin turbo Ford GT.

This. If you have to build a domestic the Ford Gt is hands down the best roll racer we've got. Other than maybe a Saleen S7. It's aero, has a motor capable of a ton of power and puts the weight in all the right places.

Ill take a new 2016 8 speed auto Camaro SS and F2 procharger with cog belt setup and some drag radials........
