Low end turbo for V6

[RonBacardi8]

G'day all,

Most members have diesels so there is not much info on turbos for petrol.
Been thinking about increasing the power for the lux.
I was thinking about saving for a super charger but was told about a turbo which would work out a lot cheaper.
Being a petrol the low end torque doesnt really kick in until 2000 rpm. So if I got a turbo for low end power would it speed up getting my torque quicker or would it just jump in rpm quicker.
And what could I expect. I know a super charger is anywhere from 6K - 11K which is a lot.

Gotta love mods but where does it stop

Cheers Ronny...

you would find a turbo wouldn't help your bottom end power any better and if you wanted it to make more power down low with a turbo it would cripple your top end power because the turbo would then become a big restriction when the engine needs to breathe. if you want low down torque i'd hate to say it but diesel is where its at


supercharger is the cheaper option as there are kit available off the shelf where as a turbo kit would have to be custom made and i don't think you would see change from 12k.

Ok looks like a super charger then if anything.

Superchargers are always better for low down, and they are instant power as they are spooled up. Turbos are more low to high but have lag where it takes time to spool up.

What power increase could I expect?
And would I have to change my 2.5 inch exhaust, cats and extractor system?

Cheers Ronny

Your exhaust will be fine, you can fit just about any supercharger system to it, the problem/money comes in with the custom chip, and engineer's report,
If I were you idd look at top mount system not side as they are better constructed
I myself prefer the kit that runs the eaton mp90, as the supercharger itself comes with a 100,000 mile warranty
I have also herd of someone in Melbourne getting around with the Yellaterra charger on a prado with a ridicules torque cure
There also the TRD factory option if you want to keep warranty
But if your looking some big hp numbers look at the Capa kit it makes 365hp, if that don't put you in low to flat 13 sec mark I don't no what will.

so I will still need an engineer clearance for it to be legal?

I dont understand why you would need an engineers report for a bolt on blower?

Heres some info on the kit from Tradewind -

Here is an 11psi intercooled FJ CRUISER KIT sitting on the packing table

Dual BOV integrated into the 600Hp rated intercooler unit, watercooled supercharger with silent trans, high spec charger with light weight internals, single belt drive, massive radiator unit, BOSCH COBRA 12V pump, high flow AFM assy with air straightener and 3.5" intake pipe all going onto a delimited 1GRFE @ 6850rpm

This will be the most white knuckle FJ Cruiser ride on the planet that is boosted with sidemount charger kit.

This LLC supercharger has one real purpose - to be silent, the cooling jacket is to simply remove heat that would otherwise be removed by the air cooling system the supercharger is normally fitted with

The transmission cooling will lower heat load to the air going into the engine but not by too much, an intercooler is still needed.

Here is the one time slip i bothered to collect

60' was 2.054
330 was 5.909

1/8 9.166 @77.55

1000' was 11.957
1/4mile as 14.311 @ 96.11mph

I raced 2 vehicles capable of 12 sec passes and neither of them bested me to 330ft, I was extremely pleased to see that, with a shift kit in the trans I am certain I can put a 13 sec pass in the bag at 3.8psi boost.

Its amazing how far the front would rise up off the line, ran street tyre pressues with zero wheel spin, only bothered to stall it up once out of the 3 passes I ran. It takes very decent car to beat the Lux to 330'.

I can only imagine bumping the boost up even 2psi more for some very rapid runs.

That's right, even if it bolts on. You can't do much to a car theis days without one.
The only chance is that the TRD had one, and you might get away that way, but I still dought it

mph is not high enough for a 13 sec pass you'd at least want 105+ mph, but must say the 60" time is good

im thinking it would be the same in the other states but here in QLD you 100%need an engineers cert for it as you are changing how the car is written down on the rego paper...and the penalty up here for driving that without one would see you in court i reckon

Well, I ran a 13.7 last night on 5.7psi on the Raptor Kit with an auto Hilux V6, I think with some adjustments to the auto trans I can run 13.5 on the same mph. Had a great run against a Mazda RX7 turbo

Here is the data (59)
