that is awesome

[importkilla05]

ok were the numbers?

[coolguy3432]

@bigretardhalo youre right i completely forgot about the difference in domed and dished pistons. and i do know the block is the same..and yeah the lower compression would make more sense anyway for the blower application..my bad lol

[bigretardhalo]

@bigretardhalo Edit should say forged pistons not forged steel...

[bigretardhalo]

@coolguy3432 Compression ratio is more easily changed with a "domed" (higher C.R.) or "dished" (lower C.R.) piston. The block may be the same I thought I remebered it being different. I do know it has a forged steel crank, forged rods and forged steel low compression (8.4:1 vs. 9:1 stock) pistons instead of the stock cast steel crank and rods and hypereutectic aluminum pistons. Once you factor in the suspension/trans upgrades as well it is a bargain to just swap the blower.

@bigretardhalo the compression ratio should be the same given the same bore and stroke of the motor..and its the same block with stronger pistons and rods lol. and i know it is cheaper just to go ahead and start off with a motor that's already built to handle boost but it just dont seem right taking off the supercharger. and besides the stock non-lightning 5.4 is a pretty stout motor anyway bc many ppl with mustangs convert their cars to the 5.4 and immediately use nitrous or boost..so idk lol

[bigretardhalo]

@coolguy3432 Because the lightning has a stronger block, crank, pistons, rods, and transmission would be my guess... along with a low "boost friendly" compression ratio from the factory.

[coolguy3432]

haha yeah, i guess it's still better than anything ill ever be able to do

@coolguy3432 haha exactly what i was thinkin.still pretty cool though.
