supercharger

[swordfishcoupe]

Now now, calm down lads

Yes, I think it looks a little better with the covers trimmed to fit (ok, quite a bit of trimming I beleive). But for me it comes 55% down to the price, but Tiler I don't beleive your charger was £6000 ish ?? I could be wrong but suspect yours is/was one of the early installs which while I am sure value for money, was considerabling more expensive than the current ones.

Tiler you car will always be a fine example of a really nice tweaked Monaro and hats off to the current owner.

Cheers
Steven

p.s. Alfa do make some very pretty engines with chrome headers. I have fond memories of a 3.0L v6 Alfa 164 Lusso (proper Alfa), but never bought it.

Right hand engine cover needs a hole cut in it for the vacuum/actuator thingy but the other one goes straight on. The SC sits in the middle.

I'm with you on the Alfa thing - lovely, lovely cars. For a while I drove a 147 1.6TS, it revved to 7k rpm and it was addictive to thrash it. It wasn't so fast to get you in loads of trouble either. I'm considering a 169 after the Monaro.

Reading all this about Superchargers, has anybody used a differnt type of one such as a centrifugal (Vortech or Procharger).
Would be interested to know how they compare in terms of power,power delivery, reliability and costs?

Stevie Turbo uses a Procharger to very good effect in his Ford Granada? Think he does 10 second quarters.

I think you can get big BHP from the centrifugal blowers but low down torque is not as good. Positive displacement blowers like the Maggie or the Harrop create max boost/torque from 2000rpm which is better for the road IMHO.

How about one of these? www.whipplesuperchargers.com/product.asp?ProdID=1230

Its worth reading up about the internals of the positive blowers before putting down the cash.
The 112 is an older model and not as efficient as the 122 which also moves more air, then there is a new tvs rotor set which harrop have made into a htv2300 kit, which is better again. The rotors, vane angles and clearances change between the models for optimisation.
The roots type blower is not as good as a twin screw, they look similar but the screw compresses the air internally in the rotors, while the roots just pumps air compressing it under the housing. At least thats how I understand it. Keene Bell website has loads of comparison info on it. But there are no twin screw options that fit under the bonnet on the Holden LS engines yet, only the Corvette.
The TVS isnt out in volume yet, so the 122 intercooled would be the best bet at present. Both harrop and maggie do them.

i've run a vortech for 30k miles now - hasnt missed a beat (touch wood) - bit messy changing the oil (sticky teflon stuff) but other than that great for road use.

torque low down isnt as strong as the positive displacement ones - which in my opinion is better (you struggle to get the power down as it is)-

rolling road figure of 530bhp at a lowly 5psi (before anyone says it - RR are unreliable... yeah yeah - so what it feels plenty fast) bare in mind hsv has different headers etc as standard over the monaros but is pretty impressive

cost - £3k - plus better mpg! quite a neat fit as well - look in classifieds its for sale regretably - not the best looking engine - agree old alfa v6 (before the holden dased new v6!) with chrome inlets looks and sounds ace - may be getting a sportwagon 156 v6 to replace the hsv

My god wormus get of the
Coz at the end of the day we all enjoy v8s fitted with a big blower.
It dont matter how ugly it is. Only joken.

Vortech TYVM

I've been fortunate to own 2 x LS2 Monaros, one with Vortech and one with Magnacharger. I found the former to be noisier than the latter, but the torque isn't as viscious low down. The Maggie is quieter and IMHO a better aka prettier (ahem) install. The headline numbers were vitually the same at the top end of the rev range.

Excellent post! Thank you. Just what we need

[I just want one]

What's the best thing about owning a Holden/Monaro?

Is it the fact you can fit 4 people in comfort with luggage (older cars) and still manage to pull away from most things.

Owning a V8 powered supercar for a while and then getting it supercharged and beating most cars on the road at least twice the price?

What have you had pull up beside you, and you've just grinned?

I've had loads, what have you had?

[mpb]

Thanks for the replies. Its good to hear about the pros and cons of various types of supercharger. It seems to be down to driver preference as both are similarly priced.

[crisisjez]

Having had both a 112 and a 122 on the same car I can deffo say the extra buck`s is well spent on the bigger blower.

Smoother, stronger, cooler and less wheezy top end.


Bottom line though guys


IF YOUR CAR AIN`T BLOWN......IT SUCKS

Just to resurrect this old chestnut

Does anyone have updated costs and comnparable dynos of the 122 / 112 and and updates on the decision making process?

(Sorry if info out there - have done search - just might be hidden)

Never took my Supra past the 400HP due to the vagaries of the turbo systems / ECU mapping out there - soooooo....

Now looking to go down the 500+HP route with the 2004 CV8 - probably later this year and just doing howework now

[ringram]

122 is more efficient than the 112, though the centrifugals, like vortec, ati procharger etc are even more efficient.
Do lots of searching on ls1gto.com, ls1tech.com, ls1.com.au etc. Your brain will explode with info, but once you collect the pieces then you will have something structured in mind

Try and drive one of each too. These days IMO no point with the 112. Id be tempted with a centrifugal for efficiency. But have gone for displacement instead.
Decide on your power goals and then figure out how best get you there for the best price. If you know you want something faster, then make sure it scares you. Otherwise you will want to spend more later

[stevieturbo]

Even a mild upgrade can seem scary at first.....

You need an upgrade that will scare you...time and time again.


Its quite shocking at what you can get used to though !!!!!! and always feel a need for more :S

So true!

[anonymous-user]

Oh yes. I pleaded with my wife to get a Monaro then I pleaded to get a blower, now she's just agreed to an engine rebuild for more power. I hope this does the trick as 520fwhp seems slow!

[Gas_Man]

I believe I heard somewhere (and please correct me if I'm wrong) that there was little point putting the 122 on the LS1 due to insignificant gains over the 112 (cheaper). I'm still trying to justify (only to myself mind) the cost of the blower. I don't mind spending the money, just hate the idea of picking the wrong one! (If you know what I mean)
Is there an unbiased (ahem) "best" option for an LS1. Up til now I THOUGHT it was an intercooled 112 set-up. Is that wrong?

[ringram]

Again.. depends on your power requirements. The 112 will move less air than the 122 and as we know airflow = power.
If you did heads and cam on a 112 it would blow a stock 122 away. Hell even just cam only with a 112 and the 122 is dead

Boost will likely drop as the engine will be able to eat more air naturally so you can up the gearing via a new pulley.

Like I say choose you power requirements and work back from there. I think a genuine 600fwhp would be fine, that should be into the 11's on the track easy with good traction.

So maybe thats a 112 with heads and cam, or a 122 with cam only etc. Im not sure I made that up. but you get the idea. You are better off to speak to the manufacturer or sponsors who have done it before. As I say take a setup vehicle for a drive or go for a drive in one. Otherwise you wont know what you want.

I took a vxr8 with 122 charger for a drive and it was pretty boring. Not sure on power, but not much over stock. Mysty posted up some gains and they were less than 10% from memory over stock. Blah blah, not going to lecture everyone on the importance of good fundamental breathing again.

Suffice to say if the engine cant breath properly in NA form how do you think its going to work trying to ram air past a closed door (valve) in a narrow corridor (port)

Get the baseline right then the supercharger will work better.
