Effects of heavy driveline componets with a n/a 4age?

[Zak]

I was thinking of making a few changes to my car, one was putting the quads back on my silvertop and running n/a for a while.

What kind of effect would the heavy 4agze fly wheel W58 and Hilux rear end have on the performance.

As far as I'm aware the standard ae86 stuff isn't really all that strong to start with, so the pro's would out do the cons?

I do have a T50 and T series rear end that I could put in, but would it be worth it? Considering I'd probably just break it.

Cheers

Why would you do that???? With all the heavy forced induction bits, it wont be as revvy as if it were fitted with the lighter flywheel and other reciproating bits, but it'll be fine.
Would be gutless as hell compared to what it is currently though! You'll really miss the low end torque.

Especially with the lowered compression

i remember when i broke the SC belt on my last 4AGZE, man that was some serious nana mobile shit.

[Zak]

Remember that the engine currently in my car is a standard silver top, 10.5:1 compression and all. So thats not a problem. The car just doesn't feel quite right with so much power, I never get a chance to open it up caus it goes to fast to quickly

I would like to do the turbo conversion at some stage, but I want to do it properly rather than just half ass it and cook the engine.

[rollaholic]

the SC is too fast but you want to go turbo? O.o

[Zak]

Yup, on a turbo, you can have a boost controller, on the supercharger, it's on or off and if I want any thing else, gotta change the pully

do you realise that the minimum boost on a turbo setup will still be more powerful that the s/c setup.

[Zak]

Yup, but it will be alot smoother, and nicer to drive.

my car, same dyno both times, s/c on 12.5psi = 101kw atw, small t3 on 10psi got 125kw atw.

same for mine 10psi s/c 91kw, 10psi turbo 131kw...same dyno

But get what you are saying zak re driveability. With turbo you can drive it n/a styles without putting the turbo into work, however with s/c it comes on straight away

[Mr Revhead]

maybe you should go n/a if your worried about having too much power

nothing at all wrong with the drivibility of a s/c 4age.... i hardly think slapping a turbo on it will make it any easier to drive. infact itll be harder if its got more power.
i sersiouly think if you go turbo itll be worse than now.
however your "worse" is exactly what most others are after!!

Thats it, if any of you went for a ride in my car, and how loud it is on boost, and backing off, I think you'd agree converting it would make a very big difference.

Not after any more power what so ever, just drivability.

err thats whats i said mate.....i was agreeing with you

and have actually been in your car before it was yours

hmm i have just uprated the turbo on my kp 60... 190kw atw wasn't enough..
anyway if you are going to turbo i'd rate the w58/hilux combo as it's what i gave behind the 1g.
If you are going to keep it s/c stick with the current setup as i'd say the hilux would sap a bit of power due to the reciprocating mass..

[rollaholic]

i'm pretty sure his cars already got the hilux / W58 setup in it, hes asking if he should put the lighter stuff back in as hes thinking about taking the SC off for a while.

[Zak]

Sorry mate, came out a bit wrong. Didn't intend to sound like a d**k

Was my car at the same stage it is now or one of the older engine setups?

[RS13]

Pretty sure Skewes had a hilux rear and W58 in his 4age DX, seemed to go alright.

[MR2SIK]

can you not have the s/c on a switch? stop the relay from engaging the clutch, flick the switch for when you want the power?
or get on of them rpm based switches set it to 5000rpm and call it vtak probably wouldnt help the drivability issue though lol.

I noticed the difference of a lightened flywheel in my old 4agze, can only imagine how noticable heavier gear would be on the 4age..

[Mr Revhead]

yes i would think a switch would be a better idea.

then you can drive it as a n/a 20v when you dont want the power
