300hp LQ4 and a 325HP LQ4 are the same. Tuning makes up that difference.

Hello Guys, last Friday when I picked up my engine, I had a 6L waiting for me on the dyno to tune. It's a completely stock engine with no mods, right out of the crate.

This engine put out 311HP and 351TQ on the first pull.

I wanted to see what timing did as it was increased:

Stock - 14-16degs : 311hp/351tq
Tuned- 20 degs : 350hp/380tq
Tuned- 25 degs : 356hp/390tq
Tuned- 30 degs : 357hp/392tq

Fully tuned with a/f ratio and max timing of 31 degs:
367HP/401TQ

Gains: 56HP/50TQ

There might have been a few more ponies left if we leaned it out just a few more points, but their wide-band wasn't working right.

Next time: stock 6.0L with 224/228cam and
FAST intake vs Truck intake.

btw just an fyi, the last 6L I tuned down there was an LQ9 that put out 441hp with a 224 cam, I was mistaken, I told you guys it was an LQ4.

later,

allen

So was this the LQ4 or the LQ9 that he tuned?

Same ratios. Essentially the same tranny with a few minor differences internally.

What is the difference between the LQ4 and the LQ9 is it just pistons? If I remember right they both run the 317 heads. Is there any internal difference,crank,rods etc. that are different?
