100 series 1hz supercharger

[dannyboy]

Has anyone ever heard of supercharging a 1hz. it would make sense to make all your power down low?

[skooter]

I have heard of it, but don't super chargers make the max hp up in the rev range? We had our 100 1hz turbo charged with garret turbo and inter cooler, and let me tell you it is a weapon now! It makes it's makes hp at about 21-2200 revs which is what we need for towing a bit trailerat highway speeds, we towed our BIG quad trailer which is about 6m long by 1.8 by 1.8 all enclosed from Perth to Walpole ( about 5-6 hrs south) and there are some massive hills in the road, and we literally didn't have to change down once!

Great Idea, and yes and being a driven mechanical device they do make power right from idle upward...........
I have had many supercharged vehicles over the years and they make great power no doubt about it, and as long as you don't get to greedy with the drive ratio's and run to much manifold pressure, the reliability factor is great.
They do however create more stress on drive components as the power is very quick to ramp up and as a result lots of load is placed down the drive train...........
The other major problem is the drive belts don't like mud etc going through them, so v belts sometimes can be more forgiving........
It is the cheapest power you will ever get.......as long as you are carful and are handy with some workshop machines...ie lathes etc to make the drive system.

Yes, I know a bloke... After it ruined 2 harmonic balancers, the 2nd which went through the radiator, he took it off and put it in the shed. Superchargers are also know to significantly heat the intake charge, something the 1HZ doesn't like.

Turbos are proven, reliable and will be cheaper to fit and maintain ;-)

If you are really keen on low down power, you could specify a slightly smaller turbocharger, but it will negatively impact your max. peak power too.

[Harb]

Superchargers should not be driven from the damped pully's on the harnonic balancer........
They should be driven directly from the centre hub, or if you wish, there are many aftermarket options.
The main problem you have with drive pulley's is crankshaft keyways, but that is only if you are running more than 1 atmosphere of boost and can be easily fixed by machining bigger or extra keyways in the crank.
But to be honest I have never done a keyway yet.
Intake charge heating is a result of compressing the air in the manifold, and is therefore similar to turbocharging, but starts earlier as a result of the earlier point of positive pressure in the manifold.
Intercooling/Aftercooling can fix that up, but it depends if you are looking for the utimate power or just a simple daily driver.........
But like greg said, if you want simple, and less hassle for the install, go with a turbo, they bolt straight on and perform, but you don't get that belt driven supercharged feeling that pushes you back in the seat right from idle....:D

Sprintex(Perth) make a kit especially for the 1HZ and it sits next to the exhaust manifold.It also come with its own drive pulley replacing the original harmonic balancer.

One of the benefits is they dont have to spool up like a turbo and give instant accelleration allowing you to shift up the gears at lower rpms.
I havent driven one but those who have say they are quiet and live up to the claims.
The screws inside are machined from a single lump of alloy down to very high tolerances ,so there is no seals to replace. The screws are teflon coated .
The kit enables the aircon and alternator to be used without shifting them.
I think on a 70 series you may hve to relocate the filter box,maybe not

The downside is $6K fr the kit + fitting if needed.

I wonder what happened to the alternator in that pic as it appears the supercharger bracket and tensioner occupies it's usual spot?

Also the intake pipe goes to the wrong side of the vehicle? If you have to relocate the air filter cannister, what happens to the snorkel?

Glad they have altered the drive system, however I wonder how good their harmonic balancer is, after all it's there to look after the crankshaft.

I once put a Sprintex on the 2H in the 60 series I had. When I did an engine swap to a 1HDT, I put the supercharger on a 1HZ 80 series that my father owns. After a few years he got hearing aids and we had to take it off because of the noise was irritating for him, but now he has new ones, he wishes he had it back again.
Both engines produced fantastic low down torque with 1.6psi boost at 600rpm, so much that the 2H was almost impossible to stop with brakes in 1st low, and would climb just about anything at idle without stalling. The linear boost means you dont get the same power surge at mid revs as you do with a turbo, and not quite as good at high rpm due to the power required to drive the supercharger (even though Sprintex tell me that the power draw is about the same as an a/c compressor) and the engines just felt much bigger in capacity. They were noisy and produced quite a whine, you could hear them coming from at least 500m away, sometimes a lot further.
The drive belts used were multi-V which were never a problem with mud, but I did break a tensioner once, fortunately only 1.5km from home, so I just kept driving with lots of black smoke from over fuelling. The pulley on the harmonic balancer is two parts with a rubber join to allow a bit of flex to reduce vibrations, and the spring loaded tensioner pulleys allow for the belt to slip when you shut down and the engine kicks backwards so it doesn't damage the screws. One issue I did have was the oil filler and level which was a standard type fuel filter with an additional cap on it, and the grease nipple for the rear bearing, both of which were capable of letting water in so I had modified those to suit 4WD conditions. I believe they are now a sealed unit.
I switched to a turbo engine, and will probably never go back to a supercharger again as the turbo is so much quieter, fuel efficient, has no maintanence, and power delivery is much better. I now have a 1HD-FTE with a few extra goodies to make it better again and it eats the supercharged engines, although I do miss the torque between 600-1000rpm.

Damo.

p.s.
That photo looks like the Eaton supercharger that they now use instead of the old "Sprintex" pump that they used to make, which had different brackets and was a slightly different shape.

[dannyboy]

i have heard you can buy superchargers from jap importers for cheap which would be the go as i have access to gear to make brackets and the like

[dannyboy]

im buying a 80 series 1 hz and have access to a free supercharger that is toyota branded does anyone know anything about them

[ROGQ]

is there any reason why you couldnt run a supercharger aswell as a turbo? that way u would get the best of both worlds. Or would it be too unreliable?

The new VW Golf (?) TSI is a supercharged & turbocharged engine. SO I guess ot workes for some :drink:

[cac]

dannyboy...i would suggest you have the supercharger off either a 4A-GZE (out of an eighties MR2) or maybe a 1GG-ZE...which to the best of my knowledge is a 2 litre straight six, but i am not sure what it is out of...

they are the more common ones you can find at the wreckers and the like for next to nothing....though toyota have put out supercharger kits for some of their newer engines....

combining a turbocharger and supercharger is nothing new really...nissan did it almost 20 years ago with the japanese spec micra....i am not sure how long VW has had the expertise to do so, but they haven't used it down under until fairly recently...

back on topic though....with a larger engine like the 1HZ...avoiding turbo lag is a lot easier than with a smaller four pot....IIRC the factory 1HZ turbo comes on boost at around 1500rpm

[BEU77Y]

I toyed with the idea... but like previously mentioned Sprintex wants $6g's for the kit.

Here is an interesting read
Cruiser 100 Supercharger (http://www.pps.net.au/4wdencounter/articles/supercharger_100.html)

Low down boosting is better but a mate has a home made turbo set up (Garrett TB34 I think) that's putting out 8-10PSI at 1200rpm. and is waste-gated at 15PSI from 1900rpm up.

[dannyboy]

i was thinking from a cost point of view i have a free supercharger i can use. the supercharger was going to go on my mate hilux (hilux v8 in the shed) but he has more than enough power now. i was thinking of using a blow of valve in a simular way to a wastegate to restrict boost if somethin causes it to over pressure.. do you think i should intercool it and what is better water to air or air to air.

how much was your mates turbo set up

[BEU77Y]

how much was your mates turbo set up

Garrett TB34 $1500 new
Garrett intercooler core $400 new
Exhaust pipe and muffler $300 (modified muffler after)
Air box home made for 3" K&N
Home made plenum chambers for intercooler
Exhaust manifold home made 40mm NB pipe bends and bits of plate
2 GU scoops $150?

About 4 weeks of arvos and weekends labour.:cry:

He put boost gauge points and temp probes just about everywhere, found a bloody steep hill (if anyone South Coast knows Huntley Hillclimb) and tuned it. He tried to load it up at a certain rev to check everything but it kept accelerating... even in 4th.

It's crazy to see the pats needed and they want to charge you $3500 at the shop. And that's for a kit that bolts straight on without an exhaust.. Not to mention the $2500 they want for an intercooler kit. Absolute ripoff.

It's on a GQ shorty with 33"s... and a I know a few people in the club with shop kits... not a patch on this thing... it FLYS! :D And he's too smart to compromise short term power for reliablity..built to last.

PS it had 420000 on it when installed... now got about 490000 and still looking good.

the vortech supercharger @ capa will give your 1HZ approx 240kw!! running at a 7 pound boost. intercooling is a must to. Got a spare 10 grand?

Sorry Eddy, but there's no way on earth a 1HZ will make 240kw on 7psi boost.

A word of caution here....centrifugal superchargers will most likely give you the majority benefit up higher in the rev range, not really where you want it for four wheel driving.

This is why, and where, positive displacement superchargers come into their own. They may not give you the same peak power and torque figures, but you will inevitably get a fat and flat torque curve from somethwhere very low in revs, typically 1000 to 1500. There is no point having massive peak power and torque at say 4500 to 5000 revs, where it's least useable. You are much better off having lower peak numbers in a useful rev range.

I reccomend a good study of the power and torque curves of both types of supercharger before you leap in.

I spent some time on this about a year ago, looking at turboing and supercharging engines, before deciding that centrifugal turbo's and superchargers weren't the way to go when a positive displacement supercharger would provide a much better outcome and much more driveable car.

Great info on supercharging and the performance gains found at low RPM's.

Has anyone put a supercharger on a 2H or 1HZ since this thread? I'm curious to hear your experiences, especially from those of you who did it DIY.

Cheers,

Rick

[FKT08]

Don't think a 1HZ will make 240kw even if you put two turbo's and a supercharger on it and if it did it would be for a very short time before you were waiting for a tow truck. Anyway who wants kw's isn't it torque we're all after:confused:

[StevenB]

just got an email back from sprintex, they don't do a supercharger kit for the 1HZ.

Anyone know of any one else doing a supercharger for the 1HZ, or would it need to be a custom job?
