subscribed for turbo install. sounds...interesting...what is the firing order?

it sounded different but I dont think that sounded anything like an exotic car. in fact I think it sounded a little worse

Sounds like a pissed off Honda..lol..

I think you can change the Firing Order with HP Tuners..but yes a different Cam would definately be needed.

I was pretty pumped to hear this thing finally and man am I let down. I feel a NA big cam ls7 sounds more exotic then this. Sounds like a chain drive single cammer honda.

The larger deg. spacing between power strokes also equals lower torque vs an cross plane v8 of equal displacement, one of the main reasons the flat plane crank was abandon for US V8's. Torque is what moves mass.

Horsepower sells cars..torque wins races.

Very true. Look at what the Audi team did with their diesel powered R18 (I think that's the name of it) with the diesel in it that made some crazy amount of torque but never spun higher than 5500-6000rpm.

That's spinning high for a Diesel..

Honestly, I couldn't find what it's redline is. So it might only be 4000 rpm, I honestly don't know.

I'm not sayin you're wrong..I've heard of that car and I know it was spinning up there.

I'm just sayin that's high for a diesel anything..in general..

Stupid. If the platform does not have an overhead cam setup, it is dumb to try and run that many RPMs on anything but a very high end race car build. Been proven time in and out that a pushrod motor has a very hard time controlling the valve train at 8,000+ rpms. Plenty of examples just on this website. Give me a 90 degree crank with this type motor any day. And no, it does not sound exotic.

I'd say you're the stupid one considering this motor is going in a tube Chassis 2010 Camaro... And no, you don't sound smart.

I think they have a pretty good idea what they are doing.

Dude, you're out of line.




So true. If I could find a cam that doesn't sacrifice low end for peak HP @ around 8K while using 2v heads, I'd be happy. Problem for me is the low end sacrifice it takes to do so on our motors (90* crank, pushrod).

I herd it went BOOM on the dyno

Jason Haines @ LPE

Drag racing pushrod engines have been going to over 10,000 RPM for over 15 years or more (Pro Stock, Pro Stock Truck and many other classes).

Road racing and circle track racing engines (short duration and endurance applications) pushrod engines routinely go to 8500 to 9000 rpm.

No specific RPM point separates pushrod from overhead cam engine in terms of maximum RPM capability - it is just a question of valvetrain mass and control pressure (valve springs, pneumatic springs, etc.).

For those that were talking about all the timing and firing order etc. That's why they're running Big Stuff 3.

meeehhhhh,


It can be done, and has been proven to be done well over 8k rpm's. Doing it old school with pushrods and 90* crank takes big $$$ too though. But, at the $/rpm and hp....I'm not completely sold that the 180 crank is really that much better than a 90*. Would really have to see what a 180* crank LS motor on nuts max effort could do before i was sold.

Have to keep in mind this one was specifically designed for FI.



It's not a tube chassis 2010. It's a SS 2010 to be raced in Real street 275 class....





Is this true!?!?!?!

CaptainDirtymax

5k rpm rev limiter iirc

there's a few sled pullers that are turning 5k+ rpm with lots of displacement. couple of Duramax's, quite a few Cummins. not as many Powerstrokes, but they're still out there.
