Supercharger Vs Turbocharger

[Matty]

i have been looking at getting a jackson racing supercharger kit for my clubman, i didnt know that it made more power than a stage one avo kit.. just more reason for me to get one now.

According to whom? Note that dyno figures either side of the pond are vastly different...

You don't need big power to go fast, the old autorotor clubman of mine only had 118kw atw and i punted that around the island in 1.57 and I'm sure in the right hands it could easily have done a 1.54.

But when it comes down to it you'd want something that was easily upgradeable because you always want more.

After having a ride in a JR supercharged car i could not beleive at just how little HP it makes for the money. its very expensive HP per $ compared to even a stock greddy turbo kit. i certainly wouldnt bother with one. id look at a BRP MP 62 supercharger maybe though.

Why would you want to spend $4.5K when you could do a DIY setup for around $1K.....

I beleive a lot of people would be very interested if you could write up a post on 'how to' do this for that amount of coin

I agree the JR kit doesn't as its only an MP42 (and comes with quite poor components). The stageonetuning.com kit for the NB however (a bigger MP62) makes about 173hp at the wheels without intercooling according to brent the guy that runs BRP. The AVO stage 1 is only 120kw or 160hp at the wheels with intercooling according to their PDF with the dynochart. I'm not saying the AVO kit isn't good, but it is a grand more expensive and in base form the MP62 has a little bit more.

It's already been written up. All you need to do is subscribe to http://autospeed.drive.com.au/ to be able to read it.

thats good mate but now that i have subscribed do i just do a search "steve818 cheap install" or what??

[glen73]

I don't profess to being the author of the article.

Search for "DIY supercharger" or something along those lines.

If that doesn't work, just manually search through the technical articles. It's in there somewhere.

thanks

This is good, exactly what i wanted to know.

My current understanding is that, contrary to some opinions, a blower kit will be an easier install (ive seen the pictures of welding and cutting sumps and water return hoses... No No NOOOOO!) It sorta sits on the side of the engine, doesnt require any fancy manifolds/dump pipes, and my current exhaust will still be sufficient...

However, a blower will be limited by the pully and is a whole lot harder to tune easily, whereas a turbo (once established) is as easy to tune as turning a screw...

I have contemplated the idea of twin charging, and have hard of great results out of the old school supercharged 4AZE MR2's where they can run a lag free 20psi plus and pull tremendous torque figures out of very small blocks. However, have not heard of this being done to many other cars...

Again, apples and oranges. Find out what an unmodified car pulls on each of those dynos, and work out the percentage power gain... I bet you'll find the AVO is faster.

Agree with Matty US Horses are smaller than Aussie Horses. Ohh and a few over there also get into the bullsh!t of \"Corrected HP\".

I like turbocharging, though twincharging is also cool. Superchargers are a lot of hassle in my mind for little gain especially the JR kits. Ohh and the loss to a turbo is a lot less than a turbo. The standard rule on the positive displacement superchargers is that to make 100hp you need to need to make 130hp whilst turbos only need to make 105hp to make 100hp (IE 30 percent loss to 5 percent loss). Though different superchargers will all have different efficencies.

Sean: I got no sound to hear it but how much timing did you pull out of it. ;)

i dunno im just looking for something reliable, thats easy to install (and remove later on), and dosent really require much maintenance... I use my car as a daily driver, so i cant be off the road for days trying to fix things that have gone wrong.

I have been in contact with BRPerformance and they quoted me $3900 shipped to my door, for one of their kits... I know this isnt really cheap, and that DIY is cheaper.. but i just cant be stuffed mucking around going here and there to get things fabricated, sourcing parts , and so on.

I would rather just get a complete kit and install it over a weekend or something. I would probably go AVO stage one if it was the same price... but im not forking out the amount of money they want for it... im not chasing big power, i just want a little bit more reliable poke, that dosent require drastic modifications..

Here's something out of left field...the VW Golf now comes in GT form, which is a 1.4L twincharger, 125kw but mega-economy apparently:

I'm hearin yah comet, all going well I will probably order mine sometime in September. This is assuming the FM butterfly brace I have coming for the car makes the improvement I am seeking. Perhaps we will be able to compare notes .

Remember that BR's price doesn't factor in any duty in Aus, though I think if you get them to call the package "race car parts" the duty will be minimised (5-10%). The BR kit has plenty of upgrades and is a far better option than the JR kit. I have noticed that the JR kit has dropped in price now that the stageonetuning one has been launched.

As said, factor in import duties. I got slugged another ~$500 to get my ~$1600 coilovers in...

so two and a bit times that, maybe count on another $1000-1500 landed...
