Would a bolt on ls1/2/3 comfortably account for the new fpv s/c 5.0

[Bingo BIlly]

Having a look at times for bolt on ls1/2/3 on here it strikes me that they are comfortably faster than the new fpv s/c 5.0.

Im thinking about doing these bolt on mods but i would like to know what is the essential set of modifications to be able to easily account for these new fpv things

Im thinking full exhaust, tune, underdrive, otr cai and maybe a diff gears? Would we agree?

[feistl]

yeah pretty much, but there is a lot more to it than just power figures. Your also comparing stock vs modified, so not really an even comparision.

It doesnt matter what other cars are making, as long as your happy with the power your ride makes. Just because there is something out there thats "better", doesnt make your car any worse.

I never understood how something can be better or worse based on something else?

I think if the goal is to be faster than a stock FPV in a straight line, your mods are a bit pointless. Gain what you want to have a good drive and an engine that makes power the way you want it to.

Remember that the next FPV you pull up next to might just have a nice tune that will leave your bolt ons for dead. It will become very expensive always trying to keep up with the Jones'

Which engine do you have, LS1, LS2 or LS3? There will be a difference in the power out put of these.

Also what car is it in as weight will also play a part?

Still from what I’m reading about the GT, if it’s tuned you may find bolt on only is still pushing sh!t up hill.

I think you might need to change the camshaft, valve springs, valve gear etc, at least and stall speed if automatic as well.
Perhaps even the heads?

If we're going to compare apples V apples spend $1500 on both and lets see what you get.
Id bet an exhaust will cost more than that and yield only a modest improvement on a LS3.
The S/C engine is already making 355rwkw with a mild tune only and Herrods are confident nearly 400 rwkw from a serious tune ONLY, no other mods...

That's pretty serious bang for your $1500 bucks.....

Yeah, if you're the kind of guy that feels big by hosing a stock vehicle with your modified one, why not pick on a more appropriate target in the first place.

Maybe go bus or b-double hunting. Make sure you post up the results in the "Kills" section

or buy a turbo, make the piping yourself, put it on a ls3, tune it, then get the plates cyafpv

Yes spot on... i cant see the rationale or logic behind comparing a modified car with a stock one... Where do you draw the line?

all good & correct posts these ones

The answer is impossible to answer at the moment anyway. The new FPV has only been taken down the track by people who have had the car for one or two days. The real times will come in the next year as they start to hit the tracks by private owners.

There is no way your car with basic bolt ons can compete with a supercharger in all scenarios anyway. Roll on acceleration you will be flogged senseless. You will never make the torque the supercharger can at 2000rpm all the way to redline. Rev the ringer out of yours and you might have a chance though.

Come on guys, I think the OP was only talking about theoretical quarter mile times against these things stock.
I think he was just asking what you would need to do to a V8 Commodore engine to match the stock quarter times of these FPV's?

Well why mention a stock FPV S/C GT at all then? why not just pick a performance target they're trying to achieve and mod to achieve that?

Are they trying to achieve a performance target or try to find a way to feel better about the car they own compared to a stock GT?

He is just using it as a "Yard Stick".
He only wants to compare how fast these things are stock?
I can't see what reason there is for anyone to get upset.

Ok.. well like others have said it will be 6 months atleast before anyone really knows how damn fast the new GT is, suffice to say there's allot of potential there.
First yard stick? FPV have achieved a 0-100kph in 4.6 seconds so there is the first hurdle.
How you get that from a LS3? i'm sure you guys will know. 80-120kph in 2.5 sec is the next hurdle..
