Supercharger v Turbo????

[tjsmudger 2]

Right, I'm seriously considering a turbo or charger for my golf vr6. It's obd2. Has a replacement engine which has done 62000 miles and seems rude not to!

I wouldn't be able to release funds till spring to complete so this gives me the perfect opportunity to do some research and find what personal opinions members have, best way to approach it(new or 2nd hand unit), approved fitters and basically what price I'm looking at! I'm impressed with other threads I've read and see it as a great addition to a fantastic car! Any guidance with be appreciated and any positives to convince the wife will be great. (she is 80% there) many thanks.

It all depends what u want from the car and how much power u want ,

[tjsmudger 2]

Power!!!!!!!!!!!!!

[tjsmudger 2]

I want power to be there when I want it. Also it's nice!

[oldmandon 1]

From what I've read, turbo conversions give greater power, but they also seem to be more larey and less driveable. Plus the dreaded lag etc.

But as said, depends what you want the car for. general driver, drag strip beast??!!

When I get round to doing forced induction, my route is gonna be supercharger around the 300 bhp region. Should be more than adequate for most situations!!!!!!!!!!!!!!!!!!!!!!!!!

This has been covered so many times fact is chargers are more expensive all sorts of power can be reached from both. One thing to remember though is over build your 6 pot lump to handle the power.

is this after talking to me

turbo all the way! superchargers follow the factory power curve, where as the right spec'd turbo can come in whenever u want. turbos dont have to be an undrivable 500+ beast, but fact is they CAN where as it would take more work to get that from a s/c. plus a 2nd hand stage 1 or 2 s/c sets u back AT LEAST £1500.....jim potter got nearly 400 reliable bhp for that

vwvortex have a great 12v and a forced induction section thats really helpful, yanks are gd at this stuff! some good threads and clever people on here too

[tjsmudger 2]

Alreet Dan, yep, I want more power. I could go the option of buying a different car altogether but I enjoy my car too much. Plus I'm buying a kiddywagon after Xmas to ferry my brood around. Thus means I can play with my car a little!

Went to a rolling road again today. Was speaking to Carl, the lad with the mk2 with turbines!

[tjsmudger 2]

I want the car to have about 260, nothing to strenuous!

Buy this :- http://cgi.ebay.co.uk/Vr6-Supercharger-/250740071780?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item3a6145dd64#ht_500wt_1156 can easily see you that BHP figure with a few good tweeks elsewhere fits some arp studding and good gasket and you should have a reliable forced VR. I want 280-300 out of mine in the new year and have already started buying the bits needed and havent even looked at a charger yet. But for these amounts of power I would go SC

[tjsmudger 2]

I like the idea of supercharging, my little g40 was brilliant fun. Might sound dweebish this but does this simply bob on and would a competent mechanic be able to fit this, cheers Dave for the advice!

[richierich37 236]

interesting, i want! 8-|

[tjsmudger 2]

What's the cost of theses redtop injectors?

[CALICO 130]

red top injectors second hand are about £100-£150 not worth going turbo for that power you could get away with just bolting a charger on (1 days work for tony ) then maybe add injectors and remap later as funds allow if you then want more power later you will need to get a spacer plate to lower the compression

[Dave_ciw 507]

As my good mate calico has pointed out for the power your after injectors and remap are not essential. Run it as is for now and when you get use to or bored with the extra power gain you can add little tweaks to improve it and then its constant growth.

[tjsmudger 2]

So I can get my mechanic to fit this, without anything else being added? Brilliant if so!!!

[CALICO 130]

yes dont know if craggsy still has his for sale £1600 iirc bolt on job done till your bored and want more power lol

[tjsmudger 2]

Cheers Calico, thanks for your advice, much appreciated.

[CALICO 130]

i'm sure tomoz when the drunks are more sober (the peeps who run / ran chargers will confirm but im sure for the power you want you wont need anything else

[tjsmudger 2]

Sounds good to me, so as a stock engine then it is pretty robust then?

[Antihero1981 8]

yeah if you only want 260 then i would say charger...

[tjsmudger 2]

Cheers everyone. Charger it is. Roll on the springtime.

LOL, It amazes me how long turbos and S/Cs have been discussed on this forum (nearly 5 years!) and STILL people never mention, or take into account, the torque delivery differences between the two :-)

260hp isn't just 260hp. BHP is simply torque multiplied by rpm. You can get 260hp train engines that make 1000lb/ft torque and you can get 260hp racing engines that make 100lb/ft torque. Two engines with the same horsepower, but drive VERY differently.

Before deciding on an arbitary hp number like that, people first need to be clear in their minds what it is they want from their car.

In a typical mid-range drag race you tend get involved in on the roads, the turbo will be a 100 yards ahead before the S/C even knew what happened.

When you want to kick some tailgating chief off your backside quickly and effectively, there's only one tool for the job, a turbo!

The Rotrex '94 can achieve similar results if you're in the right gear and rpm, but it still has no where near the midrange clout of a similarly sized turbo and it needs to run a lot more boost to make the same bhp.

Lets not forget many of us gave up S/Cs in favour of turbos for that very reason.

Centrifugal chargers need a lot of revs to make boost and that needs to be factored in when deciding between turbo and S/C. Top end power is great fun, but is that many revs appropriate and usable in your local areas?

Someone mentioned 'lag' further back but that is the most common misconception about turbos often said by people who've never tried a proper turbo engine, let alone a VR6 turbo.

Turbos are all about torque and they are effortless to drive. If you only want 260hp, then a turbo has its place there too. It will feel a lot quicker than 260 of S/C because of the torque.

And why go to all that bother and expense for 260hp? The gearbox can handle 350lb/ft reliably, so why not go for 350-400hp and make the car a LOT faster? :-)

ah Kev I always look forward to your posts in these threads :)

[craggsy 91]

But you know when Kev speaks it's the truth.

But I can also vouch for the power delivery of the two. Don't get me wrong I loved my charged VR and if it didn't need so much work to get it how I wanted it I'd still be driving it. But the turbo R is a complete different animal.

The R32 is as good pottering about as it is on boost, and will give you that kick in the back when you gun it
