My mild road race build by Byron Koury Racing Engines

* freshened ex ASA LS1 short block with Katech rod bolts
* stock 243's with ISKY 165-A valve springs
*Comp rocker trunion upgrade
*Crane 550/550 236/246 106 LSA
* 3 stage Aviaid dry sump system
* Performer RPM intake
* Holley 80541 650 cfm carb


On superflow engine dyno made:

487 HP @ 6400
451 torque @ 3900

400 plus pds ft torque from 3200-6400

We have found previously the EFI version with LS6 intake and stock throttle body usually makes a few less HP, but a bit more torque.

should be an excellent, reliable road race motor for club racing

Awesome.

sean.b

just double checking, and googling it does look like strictly an engine dyno, but that's the dyno that the flywheel bolts up to, right? that's not whp?

HP at the flywheel....not at the rear wheels

A guesstimate: 420-425 at the wheels

Interesting...thanks for sharing as always. What compression do these engines run?

bosco022

This one is a little over 10 to 1

Pump gas!

That was a big factor in my going with the ASA LS1 when I was looking for a GTA car.

Find some Pure 93 to fill the jugs and off you go.
