supercharged 4.2 patrol
supercharged 4.2 patrol
well it's been a long time coming but i have finally finished the install of an eaton m90 supercharger and intercooler on my td42. what a difference so much low torque runs 9 pound boost max 2 pound at idle full boost at about 1500rpm

well the supercharger cost 350 intercooler 150 piping and other stuff 400ish. No video yet have broken the belt due to slippage, but will get another through the week so hopefully i will get some video up soon.
and to all those that want to know why a supercharger, whynot and i also have 2 other turbocharged cars so i thought this would be a bit different

i fitted a 600x300x65 intercooler between the grill and the aircon radiator

8" drive pully goes over the power steer pully and then the power steer goes onto the same belt as the supercharger. But with a modified pully and lowered by inverting the mount and turning the pump upside down with a remote canister.

have only driven it for about an hour so far but it gets off the line so much easier than my navara. I think it has more potential as i think it needs more fuel as it dead revs at 4000rpm so some more fuel will help, but i need a piro first also a pully change could see me up to 14 psi so some more there, and due to the pipe configuration i have it wouldn't be hard to add a big turbo for a compound system . I am also still running the standard exhaust. so my system still has bugs to work out and yes i think there is more potential in it but i can't directly compare it to another turboed GQ. Iwould love to run it on a dyno for some figures
anyone know a dyno in the ipswich area

Complete waste of time without a good exhaust and propperly tuned. The heat will build up pretty quickly. Run a boost valve to control your boost. I would not be running 14psi without dropping the compression a bit. And make sure you hook up all of your return vac pipes otherwise the bearings could drop out.
Why didnt you go a water to air intercooler? No lag at all.
Keep it up, we want dyno readings

The supercharger thing has been covered before. Good on you for having a go at something different anyway.
The main reason most wheelers dont use superchargers is for a few reasons:
- engine braking (remember, the supercharger is still pumping the air in as long as the motor is running)
- belt slippage
- maintenance of the supercharger
- nobody makes bolt on kits (there's a bazillion turbo kits though)
First thing i'd be doing brad is getting some extractors and a 3" exhaust pipe on there. Making sure your injectors and pump are up to scratch would be a good idea too.

yeh coxy, the exhaust is on the list and the belt slippage is of concern but i think i have it nutted out as i.m only getting a small amont on the drive pully, just need to move the idler pully a bitfor a bit more rap.
bigboy what bearings are you talking about and i dont have any lag as it is boosting at idle. also i went air to air as ther is a big diference in price and this is a budget build

i'm only new to supercharger's and i was thinking if you could wire up a on/off switch it give back ya engine brake's for down hill's or would it muck everything up like you said?nastytroll wrote:Why would you want it off? plus it will stuff up your air fuel ratio.
Easier option = lift your foot.
cheers

possible. i'm not sure if you can fit a clutched pulley to them but otherwise they can come with bypass valve which you can rig up easy enough. you can rig it to idle switch etc which can help with economy.swbGQ wrote:tell me if i'm wrong but can you wire in a switch to turn the supercharger on/off?
if you have a boost comp then air/fuel ratio won't be effected much.
ok thanks for that mate, main reason i asked is cos i'm thinking about supercharging mine for something different and i hav't heard of one in tassie yet, but i don't want to loose me engine braking for down hill'stweak'e wrote:possible. i'm not sure if you can fit a clutched pulley to them but otherwise they can come with bypass valve which you can rig up easy enough. you can rig it to idle switch etc which can help with economy.swbGQ wrote:tell me if i'm wrong but can you wire in a switch to turn the supercharger on/off?

Wouldnt you get engine braking anyway if you've got your foot off the throttle? Your not putting more fuel in so there wouldnt be any accel, thats the way ive always looked at it anyway.
As for the switch, not sure bout the mustang type but im pretty sure there the same as the commo one, but no there is no wires for the clutch, thats only on the toyota ones that i no of. I thought the bypass valve was inside the supercharger unit itself, and theres a vacuum line that connect to it and controls it, not a good idea to disconnect it tho.

good point mate, i guess 92mav will be able to tell us if his still got or if his lost his engine braking.SilverBulletBM wrote:Wouldnt you get engine braking anyway if you've got your foot off the throttle?

The Toyota superchargers have a clutch setup similar to an A/C clutch, and yes, you can flick it on/off as you please.
As for engine braking, when you take your foot off the accelerator pedal, you are cutting your fuel dosage back to the equivelent of an idle (maybe a bit more due to pump timing etc). When you have an air pump (the supercharger) feeding 2psi of air at idle (around 89CFM [600RPM]), basically you are loosing a lot of effective engine braking as the engine is being fed air rather than just free-running with an atmospheric pressured 89CFM.
Please, if there's any diesel/supercharger guru's here, correct me if i am wrong.

Yeah, Its like a Air cond pully with magnet, but anything over 5.5psi will break clutch.macneil wrote:he means for when you are going down a hill so you have engine braking of a N/A td42 then flick it back on when its needed..
u beat me 2 it.. and i belive its not an on/off switch its a clutch enguagement on the pully.. I think!
I installed this one on ecotec, clutch on/off but for more boost have to loose clutch

I cant say there was any difference in engine braking either. But ours was a petrol. We supercharged a the engine with a aisin supercharger of a (1ggze) toyota soarer engine. Got it from all jap imports for $300, its a fully sealed unit with a clutch and on/off wirring. Pretty easy to do. Basiacally the same as what youve done. Work out how fast the teflon coated blades can spin at, work out pully size back to your revs incase someone red lines it. Bolt pulley to engine, line up and mount supercharger with a tensioner.
I can definately see how 2 psi at idle will affect it though. If you can set it up back the 0 psi then it should brake normally.
Couldnt you make the same arguement with a turbo (exhaust enduced supercharger) as to when your braking and the revs are still up your creating exhaust pressure that is still adding boost?

I thought engine braking was also a result of the closed throttle making the engine work much harder on the intake cycle, ie it's drag due to the air intake being highly constricted. So if you have a supercharger in theory it is going to overrule that effect a bit.SilverBulletBM wrote:Wouldnt you get engine braking anyway if you've got your foot off the throttle?

But I guess it comes down to how much difference it makes in practice.
