Pistons and rods etc keeping same compression does not effect performance. They do the same thing. Add to reliability. And they are both internal mods.

so drop in pistons lt1= bolt on?

I’m just here for the tuna, man.

So, your are saying that the LT1 rods and pistons ARE NOT reliable? Oh boy....

Wonder if that’s addressed in the C8 or it’s going to be the same situation? Could be little difficult to swap the pistons in a C8 but maybe they have been corrected, I don’t remember seeing a mention yet, but I haven’t looked too hard either.

The coyote opg get swapped out because some owners don't think they are reliable for their intended use. (2steps and limiters)

Wonder what TR is getting at with the LT1 rods and pistons here..... I'm not convinced they are unreliable.

I already said OPGs not a bolt on. Neither is drop in pistons. Im not sure where this is going. Usually tunes with boosted LT1s have to be concervative in order to protect piston, either by extra enrichment or less timing, same with coyotes at around 800whp. Once drop in pistons and rods get added most people will send it. So although those don't add power, they allow it. OPGs doesn't allow for more aggressive tuning. Lund wont say, "oh **** Carlos, you added OPGs and CS? Hold up let me throw extra sauce at it!", but likely would if I said I have forged rods and pistons.

If I keep the Mustang (trying to not buy another C6Z get my wife upset) I’m not swapping them out. It’ll be Hellion Sleeper kit but no opg’s.

I was looking at LT N/A vs F/I research last night and I ran across Pony Wars video (hadn’t seen it before) and from stock to the $5k budget the 17SS out dynoed, et and trapped the 17GT - in the 1/4 mile. Pretty straight forward the LT is a beast.

Then they added the Prochargers and said the Mustang wanted a more rounded build where the Camaro was looking for all out power and therefore they pulled the LT and replaced the pistons then did suspension work to the Mustang.

Then the LT dynoed 20hp more, but here’s where I noticed something odd.

This isn’t to knock anyone or car at all just observation on the video.

The Mustang ran quicker et and trap with less power and now they weren’t testing 1/4 mile as 2 previous times, they were testing 1/8 mile?

I’ll post screen shot they have in vid. Wonder why it went from1/4 to 1/8? They both (autos) should pick up 30 mph on the back of the track. Odd to me.

The tunes aren't conservative to protect the piston. They're conservative to protect the rings.

Ive mentioned several times ways to address that.

The lt dyno'd only 20 more hp.....tq is power. And it smashed the mustang in tq.

Now......using the power is another issue. All that tq is harder to control. Because tq is power.

They were having issues with the power of the camaro getting it to hook up.

Great series tho. I can't say i would choose some of the same mods but they did decent overall on how most mods those cars.

NoEngineNawledge

Probably why SXC’s car runs so well. Has a laundry list of suspension/chassis mods & not nearly as many “power” mods.

BlkMach1

Honestly don't care if its protecting the tooth fairy. Just going by what ive heard their vendors and shops say. My comment is still valid, IF Poppa had OPGs its no difference than a z06 with a "fixed" head. Still a bolt on car.

UltraZLS1

iTrader: (13)

not even close to valid

you are comparing a stock replacement part to an improved non oem one.

and first you say opg isn't a bolt on...but then a car with opg is a bolt on car?

you've lost me

Depends on the octane. You see lots of sub par running boosted LT1's because they are running 93 on stock fuel system. Tuners have them running 10-11 degrees timing, so they don't end up running very well because that low of timing just ***** on the engines efficiency overall. Lets compare...8psi 93 octane on 11 degrees timing vs a bolt-on E85 car running 29-30 degrees timing. Gee I bet the blower car makes slightly more peak but probably not much difference in average power. Part of the reason why I spent the money on a fuel system so I can run E85. My timing is around 21 degrees which is only 3-4 less then a stock LT1 timing map on 93 pump.

My advice is to stay away from 93 and run a mix of E or if no E then use Meth with pump. LT1 needs the octane and cooling so you can keep the timing up...makes a world of difference on the outcome. Not sure why so many have trouble grasping this. The LT1 can not even hit MBT with 93 pump NA, which is why they gain so much power from just a flex fuel tune and E85. So trying to add boost with 93 on a engine that can't even reach peak timing NA doesn't make a lot of sense in my mind. All these Supercharger companies try to sell kits claiming you can, but that is only because if added in the fuel system upgrades to the cost of the supercharger to do things correctly, the OEM probably wouldn't sell nearly as many kits.

Far as the argument of OPG or crank gears, if it's not a part that came in the engine then it's not SBE....bolt-on or not. Same goes for anything GM needs to help it support more power. You guys need to just let these Stips die...for real. Do what you need to do to make the car handle the power more safely within your budget. It don't bother me if Nanner had OPG, big deal. His car ran good I give it props.

Sxc has rockers?!
So non-bolt on car vs non bolt on car, Poppa absolutely ravaged that booty.

BlkMach1

Sounds like you're easily lost. Not a bolt on. For all arguments when it comes to adding power Poppa had a bolt on car. DB had or has a c6z06 that they basically went in to the heads to prevent it from failing during operation, they said nothing else was touched, I believe them, its still a bolt on Z06.

Once again, Poppa went faster with bolt ons than the other fella with the Auto LS1.

BlkMach1

If thats the way they want to go....Poppa wins anyways LOL.

sxc Z28

My car has stock rockers. Valve covers never been off. Good try tho NoEngineKnowledge living up to the name. Didnt yall see my mods above or we ignoring that now too?

Any bolt on coyotards in here beet my ol bolt on ls1 yet?

sxc Z28

So yall all lost is what youre saying lol

snake95

So if Poppa would have switched stock OPGs back on, then it would have been legit?
