Duramax???

[Camaromax]

thanks for the input again

camcojb - sounds like your the guy to be talking to on here about these diesels. So if you were to build an engine for this car with a target of around 600hp how would you go about it? Would you just add head studs, Do the above fuel mods you mentioned, and some programming?

I was looking at PPE's site and they show programers adding 425hp has anyone tested these? If so what were the result and what other mods were done with the programming?

Also camcojb they say that every 10lbs is 1hp so in a car weighing 300lbs less than a truck that 3000 lbs would be like adding 300hp. I am sure that is just an estimate but I would think that 3000lb difference would at least put the car in low 11s if the truck is in the 11s at all, possible high 10s. All while getting 23+++ mpg.

I would do the head studs since it's so easy with the engine out. I also would go with EFI Live instead of a PPE tune. Nothing against Dan at PPE, great guy and very good tuner. But his performance tunes are as much or more than EFI Live, and with his you can't do the tuning changes. With EFI Live you can change anything in the tune so if you want to try more boost, change the fuel, timing, etc. you have immediate access.

The biggest problem you'll have is traction. The street trucks that are the quickest are almost always 4wd, and there's a good reason for that. Even though the 4X weighs more and has more power loss down the track due to two diffs instead of one, they launch much harder and traction is way better. The 2wd trucks are rarely as quick as the 4X's, unless it's a drag specific truck, because they cannot hook 1100+ rwtq. You're gonna need slicks for sure for any track duty, and it'll still be a learning curve to get the car to leave decently. If you get it to hook well, you'll easily run 10's I would think, but not sure how easy that will be to do. Mileage, can't see any way you can't get well into the 20's on the freeway.

ok, this thread just caught my intererest beyond making suggestions.... mabe my euro-diesel suggestion was from only having ridden in a tuned Mercedes 400 CDI, vs a mild tune 24Vcummins, and the merc was infinitely faster and smoother...

but how much is a Duramax take-out engine... what manifolds do people run with twins.. fabricated logs?? what else, appart from the engine and a feed pump is required to make it run in a swap... how much does it weigh???

So some of my concerns now are:

1. Fitting in the engine bay due to height?

I am thinking possible dry sump to allow me to lower the engine down as far as I can so I can run a small cowl hood. If Chevy can run a dry sump on a production Corvette why shouldn't I be able to do so on my Camaro.

2. Traction???

What type of rear suspension to run? I am definitely not keeping the leaf springs I actually plan on doing some sort of custom frame. I am leaning toward using either a triangulated 4 bar or a torque arm style rear suspension, but I was thinking of only using a 285-305 rear tire???

3. Gear Ratio??

I am planning on using the Allison transmission so I need to figure out what gear ratio I will have to use to make the gearing similar to the trucks. to do this all I need is a rear gear ratio and tire size for the truck and convert that gear to be the same with the tire size I plan on running with the Camaro.


Please give any input on the above problems.

Thanks

1. should be able to, no idea where to get one.

2. good luck with traction..................

3. the trucks come with 3.70's but you'll need a much taller gear as the trucks have a 32" or taller tire.

How much does a Duramax/Allison weigh in comparison to an aluminum headed SBC or LSx and T56?

What would the car weigh when done?

That would be my biggest concern as well. How much nose weight are you going to need to make kit work. I am really impressed with my handling even with a big block, but I have a feeling you will have much more nose weight. I also have a DSE subframe. What are your plans in that dept?
