Just another 450whp Turbo FT86 -- and NOW 530hp

[FRS Justin]

I really don't think its a brand specific failure considering N/A , Turbo and S/C have all failed for one reason or another...... So to place blame on a individual brand is probably more speculative than factual.

Graph was for a WRX which has better rods, he was saying it would be dumb to do the same thing on an FR-S.

I know what he was saying and what the graph was for. I was saying it was comparing apples to oranges because it had lower compression and much higher boost...

I said it would be foolish to try and run the same amount of boost on a stock bottom end FA20 and he said he was doing it already.

I said you can't have it both ways... If you're doing it already and it's not safe you're either not very smart or you WANT to see it grenade...

What if I told you... boost is irrelevant?

I can drop a 72mm turbo on the car and make 500hp on 7psi.

What then?

[seito23]

the volume of mixture, in conjunction with timing, fuel and richness is where the magic happens.

Wow... This discussion about boost and motors is really long but anyways...

Vit has tuned two of my three cars that I've had, and plan on him tuning my brz too. He knows his stuff, and has tuned many. He has a great reputation. He knows what he's doing. Plain and simply, he's awesome. Nice job on your frs Vit. Make my brz awesome like you've made my civics.

Note: take what he says Seriously.. He tunes for a living for a reason. He's not some random troll like us.

This conversation has become pointless lol.

To be fair, in between people giving Vit a hard time... Vit has taken it in stride and kept sharing some good nuggets of info.

The other stuff is just.

VE won't let you...


You can only fit so much air in 4 86x86 combustion chambers.. boosting it allows you to fit more...


Yes that turbo will flow enough air to make 500 hp at 7 psi, but there's no way you will ever get enough air into a 2l engine to make 500 hp at 7 psi...

*whoosh*

You should just stop buddy, because this post clearly shows you have no idea how turbos actually work. Again, PSI != CFM. You've been told this already, yet you're still arguing based on boost level.

Just stop... you're embarrassing yourself at this point.

VE? where's your TAF to show this isn't possible? I think you may be confusing volume and velocity. Our FA20 heads flow as much as some V8's, adjusting other variables 500hp is easy. Not breaking something in the process, that is why you hire guys like VIt.

You said,"You can only fit so much air in 4 86x86 combustion chambers.. boosting it allows you to fit more..." So which is it? only so much or boosting fits more?

Even if those COULD shock the piston and by extension the rod. <phrasing>
He is using timing AND PSI and boost by gear to minimize stress.

sit back and enjoy the show.

I never said psi equals cfm. I said the opposite...


Here let me spell it out for you.


you have three factors here...


You have the volume of air that will fit in the chambers... You have the volume of air that the turbo supplies at a given boost level, and you have the boost level.


Regardless of which turbo you have, you still can only flow so much air into the chamber.


With a bigger turbo, you have more flow at a given boost level, but there is STILL a limit to what the chamber can fit and flow.


To get to a certain level of flow, you HAVE to increase the boost level regardless as to what the turbo is CAPABLE of FLOWING...


SHOW me ANY instance of a 2.0l engine making 500 hp on 7 lbs of boost. You can't because it doesn't exist...


Jaden


The only way a turbo capable of flowing 35lbs a minute of air at 7 psi is going to actually be able to flow that air into a 2.0l engine AT 7PSI is if it's a compound boost setup and then your final boost level will be MUCH higher. You need to flow 35 lbs a minute of air into the engine to make 500 hp and I'm sorry, you just can't do that at 7 psi on a 2.0l engine

where is this magical 2.0l making 500 hp at 7 psi... brick wall?, you need to be looking in a fucking mirror.


The heads in this car are REALLY good at flowing air, but you AREN'T going to be making 500 hp on this car on less than 15 lbs of boost..sorry...


Jaden


p.s. so you're making 470 whp on your brz... What level of boost are you running again???? must be 6 right? stop, you're embarrassing yourself...lol Oh I know, you've got too small of a turbo...
