Very cool. Great work.

Nice sig BTW

 

That's an Avatar.

 

oh right. I think I'm still drunk.

 

at Avatar....

What size LSX are you considering building? Even though those turbos are rated at 1000hp each, on what size engine? If you have too many cubes they can likely choke before they make that power. And what A/R?
The 1200hp Hot Rod 4.8 turbos were the opposite.....small turbines and 76mm (I think) compressors.

 

Sweet build and my favorite body style!

 

The title of the thread should read:

"Project: No Talent"

 

Guy's turbo's cost more then some peoples whole kits! lol

 

I didn't try that per se, as I'm sure it would work as advertised. Just curious if anyone knew. In any case, I won't be testing the diff on anything more slippery than gravel/dirt lol

LSX376-B15. If the turbos can flow the air, I will build the engine to accommodate it. I've finally got a standalone matlab license again, so I've been working on a model for engine airflow estimation to back-calculate a camshaft profile to optimize for the turbos capabilities. Believe I saw an Evo make like 868whp with the 9180, so I should be able to double that. The truck has more drivetrain loss, but it'll likely be more efficient.

But experience is George's favorite word...it just felt right.

 

Indeed.


Nice. What I wonder about is the Evo is what, 2.5 liters or something? Twice the engine is only 5 litres. Will be interesting to see if those same turbos can move the air that a 6.2 will produce.

 

The evo was a 2.0l. The turbos don't know what size engine is feeding them. All they see is the exhaust flow. All else equal, a 2.0 at 10k rpm looks like a 4.0 at 5k looks like an 8.0 at 2.5k....etc. I may not be able to crank out as much rpm, but I really don't want/need to anyway. Max recommended rpm for that engine is 6600 which is still plenty.
