We completed our first test on a solid roller 346 cu in LS1, and here are the results.

We had a balance problem. The engine is apart and getting some new design pistons,and some
other head work. We are going to try some other cams while we are at it. this is just a test
bed

This engine was built to run 8000 rpms. The LS6 manifold runs out of air at 6700.
This is why the hp flattens out above that. The cam should have a power peak at 7500.

We are shooting for a power peak of 7500 to 7600 rpms, and a peak rwhp of 500.
We are waiting for a new manifold to do this.

The thing to notice is that if this car was shifted at 7400 rpm it whould never fall
below 450 rwhp.

Stay tuned.

Thanks

Nice, if you need a an extra test car, let me know.

Very nice results from a 346 cube engine.

 

Heh... looks like I'll be swinging by LG in the next few days...

 

Holy schmoly Lou,that is impressive.

 

JMG5X-2, I mean JMX

I agree Can't wait till we get a better manifold. Just think about this: At 8000 rpms the pistons go up and down 133 times per second. So the manifold is trying to move air at that rate also. And the intake valves open and close 67 times per second. That is 67 pulses of air per second also.

But I love RPMs. We shifted our Trans AM C5 Race car at 9000 for qualifying!

This engine has a stock crank, forged rods and pistons.

PS, Jack (burnout) where have you been lately?

 

Very impressive Lou! this may be the Open Road Race motor I have been looking for!

On the intake issue, have you thought of maybehaving Hogan's build an intake for that motor? generally speaking a sheet metal intake is only really good for the stroker motors but if this motor is intended to run around the 8K mark sheet metal may be the way to go. Just my .02.

P.S. when you gonna let your kid navigate for me?

 

Even if you shifted 4th to 5th in a non Z06 car? ;-)
You especially should know what a pain in the a$$ that shift is on a road tack...

(watching solid rollers with interest)

 

What manifold are you thinking of using? Just Wondering.

 

The numbers are definitely impressive, when I visited LG last week I saw that dyno graph in person.

Im surprised nobody has asked the BIG question.... Spill it Lou, whats the cam specs

 

****This is in no way meant as a bash- Great results*****

Why are shops still spending R&D money on solid roller setups that require custom intakes ($$$$) to get 470 RWHP out of a 346 when 470 is attainable with hyd. roller?

Is it just for Higher RPM (more area under the curve?)

 

MEMEMEMEME I can answer that one......


Cause the 470 HYD setups ARE BULLSHIT Take it to the track

On a more serious note, this 470 was done wiht an LS6 intake and as he said, hes hoping for 500rwhp with an aftermarket intake. Solid rollers have a killer topend pull. DO some overlays on solid Vs hyd and check out the difference in power at different RPMS.

 

Very nice numbers, nice setup,

 

Gonna have to agree with Cammin even if the car pulls some great numbers it is always done with many tricks open headers, short belt, no air filter etc. Take the car to the track and a Solid Roller will walk all over those so called 450 plus hyd. motors.

 

Lou-
Is my LG 442ci solid roller done yet?

 

Because as soon as we get a better intake, that number will climb into the 500's... Also, try to rev a hydraulic cam that far.

 

Nice numbers lou, i'm confident that you'll hit 500rwhp soon enough.
