i'll need to get lotto ticket first . you need to take it to the track

 

?????

 

oh **** son. which engine is stronger internally though?? im sure someone knows

 

Should be the same minus the head. Cast pistons, forged rods, crank.

 

all aluminum though

 

The SS/TC will be far stronger internals compared to the LSJ. I mean come on, common sense says so with forged parts...

 

the lsj has forged parts

 

not the pistons. but i thought the lnf was the same way...

 

i know i was thinking the lnf and lsj were virtually the same with minor differences, i dunno though

 

i want to throw my 05 ss/sc on the dyno and see what numbers i make

its pretty much stock with an airbox mod but for some reason its faster then an 07 ss/sc and has a 1/2 car in a ss/tc
stock vs stock

 

nice numbers i wonder what mine throws down

 

tuned with HPT?

 

yup all hptuners

 

Nice numbers. Any chance you have a chart with SAE correction applied? Depending on atmospheric conditions standard can produce higher or lower numbers and SAE (usually a touch higher) and SAE makes it easier to compare to other cars on similar dynos across the country. Either way, I'm not half as interested in the peak numbers as I am in the overall curve. That looks really nice with no giant spikes and solid gains across the entire powerband.


Both engines use cast aluminum pistons, both of which (along with the rods) are made by Mahle.

 

so basically the power it can hold is basically the same as the lsj?

 

different engine. you cant tell

but im sure some redline or gxp dude should know

 

i know its a dif engine, but blackbird said they both had cast alluminum pistons

 

has nothing to do with it holding the same amount of power. head might flow more, rev limits, etc

 

It might be able to hold as well or better but there are some significant differences between the two engines. For example the pistons are both cast aluminum but the design on the LNF is completely different due to the direct injection nozzle placement. The LNF also runs a slightly lower compression ratio. The fueling system is also completely different and the direct injection setup with the resultant different flame front in the combustion chamber may prove to have significant differences in how the LNF will make power and what it can support. The LNF also uses the newer and stronger/reinforced Gen II block but still uses cast iron cylinder liners.

Both engines should have similar max power levels they will support but both will probably require upgrades if you really want to push them far and maintain the best reliability. When trying to make direct comparisons between the two you'd also need to consider things like possible uneven fuel/air distribution and high charge temps due to the blower on the LSJ contributing to internal failure when pushed too far, which should no longer be the case with the LNF and the new intake manifold and fuel setup.

There's lots and lots of variables. By the spec sheets they do look similar but a lot of factors may come into play in the power levels the internals themselves will be able to support.

 

eh it will pretty much be the same power wise, just probably a little better top end with the VVT probably hold a little more boost on pump gas with the 9.2:1 compression vs the 9.5:1 compression. mostly has to do with the tune and how big of a tard the driver is.

 

were not talking about the blower.

 

just throw a big turbo on it and lets see.....

 

ahh missed that...

thought hpt wasnt technically released for the ss/tc yet?

 

i think its been out for awhile i know psycostevo has been tuning them for some time

 

Yeah its out & supported in the newest public release, we should have the 09's in beta in a few days as well.
