Possible V6 - 170 inch dragster project

so im looking at a new possible project.
when i was back home the plan was to build a chassis around one of the 60* motors ,mainly a 3.6 di motor or the 3.6 out of a caddy and run it with twin turbos.since ive moved theres no way in hell i could actually build it myself now.

i did come across a 170 inch roller for pretty cheap ( no body ) though so it got me to thinking.

the roller is setup for a 2jz but it looks like my 3.0L v6 may go in without to many headaches

so im thinking about getting it and d oing this project instead of putting my 3.0 into the firebird

either wich way it would only be a drag car, if i stay with the firebird it would be possible to see some street time, the dragster obviously not lol

what do u guys think?

my main thing is while it would be cool theres not really a class to run a dragster like that in,but even still im sure it would be a blast to drive down the track

Re: Possible V6 - 170 inch dragster project

Go look at Comp Eliminator vehicles. You'll see all kinds of weird combinations. 4 cylinder big blocks, inline 6's and even V6's. Not everyone wants or needs a big V8. They use odd engine types to fall into a particular class.

I've seen a 4.3L V6 in a 70's or early 80's chev pickup truck run high 14's. My basically stock 454SS barely can do that.

i need to get myself a current rulebook, hell i dont even have an old rulebook here, r nw maybe one of u guys could look up some stuf for me.

would a 3L v6 with twin turbos fit into anything in comp eliminator

any restrictions on turbo size ?
limited to single turbo?
and is e85 legal?

motor is currently setup to run e85 but if it fits into the class and can be competitive i could always switch to race gas

Re: Possible V6 - 170 inch dragster project

You would need to pick up a current rulebook as class requirements are always changing from year to year as racers keep wanting to try new things. I don't think there are a whole lot of Comp Eliminator classes that allow turbos and the ones that do are usually limited to one turbo. I don't think any class is allowed to use E85. I believe all these classes must run a spec race gas C12, C14 etc. Only a couple of classes such as Nostalgia Dragster are allowed to run methanol.

Personally, I doubt you could whip something up to be even close to competitive to run in Comp Eliminator. Just about all of them including the 6 cylinder rides are in the 9's or quicker. It would probably be cheaper to build a ProStock car.

I don't have a current NHRA rulebook but you could build something to run in SuperComp, SuperGas or in the ET class as those classes have very little limitations on what you can use as a powerplant.

I've seen a FED with a very mild SBC run 10's all day long. Staying out of the 9's means it doesn't need all the extra safety requirements and only being a mild engine, there's little to no maintenance.

Now just because the NHRA or IHRA don't have a specific class for what you're trying to build doesn't mean you can't built it. You can normally build just about whatever you want and run it in the ET bracket class as fast as you can make it run.

Before you buy the roller, make sure it has a current chassis tag or a guarantee that it can get one. It could be cheap for a reason. If it can't pass a chassis certification for any reason, it's stuck running 10.0 and slower. The welds could be fatigued, the tubing size or thickness may not be sufficient etc. Old chassis are usually retired for a reason.

Re: Possible V6 - 170 inch dragster project

chassis is only 2 years old from what the guys says,its out in texas so id have to drive out to look at it myself,im waiting n some measurements to see i the 60* v6 will it in it

the twins would have been more for appearance to keep everything symmetrical looking

the 3.0 i would use has a single gt45 on it and made over 500fwhp @ 22 psi. swap to a bw s475 or s480 and it would pick up some power

but it should run pretty well in a light chassis

fuel maybe a problem as i built this motor with the intent on running e85 or methanol, its a high compression high boost engine 11.03-1 cr with plans to boost it around 28-32ish psi

Re: Possible V6 - 170 inch dragster project

In theory it could be fun, but unless it fits some class it could end up a pretty big source of frustration also. Why is it being sold anyway? I'd be worried about problems there.
